User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8.1) Gecko/20061010 blub Build Identifier: Lightning 0.3 Build 2006100618 on Thunderbird 188.8.131.52 It's not possible to open a .ics file with a double click. Additionally there is no error message stating that this is not possible. Reproducible: Always Steps to Reproduce: 1. Double click on a .ics file 2. Select thunderbird as application Actual Results: Nothing happens Expected Results: events in the .ics-file should be added to the calender
I can reproduce this bug in Lightning 0.4a1 build 2006103107. Opening a .ics file using Thunderbird with lightning installed does nothing, not even a warning message.
I think we can confirm this. If Lightning is the only calendar application on the user's machine, then we should be associated with the ICS files on that machine.
Since MS-Outlook delivers .ICS files, I would think this should be a critical fix in Lightning.
dupe of bug 362285?
Four years old and 31 votes, yet no movement. Sigh. This would also handle http://getsatisfaction.com/mozilla_messaging/topics/automatic_opening_of_icalendar_ics_email_attachments. Thunderbird already supports opening EML files on the command line (#242959) and its possible for extensions to process command line arguments (http://support-calendar.1097866.n2.nabble.com/Open-ics-files-with-lightning-td3769107.html).
Seems like there's an issue as to how to interpret opening it. It could mean you want to import the events into some calendar, or it could mean you to create a new calendar + calendar subscription. Other bugs, possibly duplicates: bug 261460, bug 423374, bug 359807 Looks like there was a command line handler rewrite that got abandoned...

They got this working for VCF/vCard files in 646638, can you build on what they did for ICS/iCalendar?
Sorry, here is an actually link to the bug 646638 (forgot the bug keyword) Also related (but not implemented yet) is Bug 694891 - File opening should be extensible
The patch in bug 646638 is the easy part, we could probably add a command line handler that fixes that quite easily. The hard part is actually registering this with the OS. On windows we can't just do it natively, we have to use a helper app that requests UAC access. The helper app being used for Firefox/Thunderbird is currently a nsis script that isn't very much extensible. We could probably change that script to add parameters as to what extensions should be added, but I could imagine it coudl become a source for exploits.
It has occurred to me that _where_ you double click is not clear in this ticket. (ideally double click on a .ics in the OS would be great) BUT, For me the main frustration is that I cannot double click an .ics attachment in an email from within thunderbird - it asks me what app to open it with, when I'd prefer it was handed to Lightning to load or import. Generally meeting invites work OK (accept decline) - but sometimes I recieve .ics files (from mac Outlook), which has an empty body, and an .ics attachment. Thuderbird/lightning doesn't seem to identify it as a calender entry (there is no accept/decline option presented for the message) - (a mac mail client seems to load it OK if you click it) - so from within thunderbird, I end up with an .ics file I can't do anything with. my next step is to either save it locally and then import it (forget it!) better would just be able to double click the file (within Thunderbird) and have lightning at least try to do something with it - or tell me that there is something wrong with the file format When I read the email in thunderbird (empty email with an ics attachment), thunderbird doesn't seem to be able to do anything with the .ics attachment. Here's the contents of the meeting.ics file from Mac Outlook / Entourage: BEGIN:VCALENDAR VERSION:2.0 PRODID:-//Microsoft Corporation//Outlook for Mac MIMEDIR//EN METHOD:REQUEST BEGIN:VTIMEZONE TZID:Canberra, Melbourne, Sydney X-ENTOURAGE-TZID:51 X-ENTOURAGE-CFTIMEZONE:Australia/Sydney BEGIN:DAYLIGHT TZNAME:Daylight RRULE:FREQ=YEARLY;INTERVAL=1;BYDAY=1SU;BYMONTH=10 TZOFFSETFROM:+1000 TZOFFSETTO:+1100 DTSTART:20111002T020000 END:DAYLIGHT BEGIN:STANDARD TZNAME:Standard RRULE:FREQ=YEARLY;INTERVAL=1;BYDAY=1SU;BYMONTH=4 TZOFFSETFROM:+1100 TZOFFSETTO:+1000 DTSTART:20120401T030000 END:STANDARD END:VTIMEZONE BEGIN:VEVENT UID:DEC40C2B-0ECD-4670-B04F-A2CEA3EFC8AE X-ENTOURAGE_UUID:DEC40C2B-0ECD-4670-B04F-A2CEA3EFC8AE DTSTAMP:20120209T044900Z DTSTART;TZID="Canberra, Melbourne, Sydney":20120214T080000 DTEND;TZID="Canberra, Melbourne, Sydney":20120214T090000 LAST-MODIFIED:20120209T044900Z SUMMARY:Haydn DESCRIPTION:As discussed….\n LOCATION:BlueOlive ORGANIZER:MAILTO:email@example.com SEQUENCE:0 ATTENDEE;ROLE=REQ-PARTICIPANT;RSVP=TRUE;CN="FirstName Lastname";PARTSTAT=NEEDS-ACTION:MAILTO:firstname.lastname@example.org X-MICROSOFT-CDO-BUSYSTATUS:BUSY X-MICROSOFT-CDO-ALLDAYEVENT:FALSE X-MICROSOFT-CDO-INSTTYPE:0 BEGIN:VALARM ACTION:DISPLAY DESCRIPTION:REMINDER TRIGGER;RELATED=START:-PT00H15M00S END:VALARM END:VEVENT END:VCALENDAR
Another place is ICS files in Firefox, that is where I run into them all the time (Southwest, Meetup, Facebook, etc). Outlook and iCal handle them easily. For TB I can easily bind the ICS type to TB using the normal Firefox dialog, then Firefox happily passes it on the command line. Unfortunately Thunderbird then treats it like an attachment. So if you could do the "easy" part I would actually consider it to be a huge improvement. For OS level, in Windows even if TBird doesn't create the mapping itself, users can easily do a Open With then selecting Thunderbird in the applications list and checking "always use with this type of file". So its a simple use manual step to meet all the user needs.
In TB 10.0.2 and lightning 1.2 on windows7 this issue is still very much alive. I changed the file association on windows for the ics file type to TB, and I got rid of the file association in the TB Attachments option...now when I double-click on the attachment it opens in a text editor. If I save it to the file system, and then double-click on the file, it opens up a mail window. Lightning doesn't see the ics at all, even I manually import it using the Events and Tasks menu item.
I agree with David Taber... this is still an issue. to accept an .ics event into Lightning from a webpage I have to click the link, then select open with Thunderbird (treats it as an attachment in new email), then send it to myself. Then I get the accept/decline option upon opening the email I had to send to myself. Too many steps! I would expect to click the link, open in Thunderbird, see the accept/decline option.
(In reply to Mike McDougal from comment #22) It's cumbersome enough but not nearly as cumbersome as described in comment #22. - in browser right-click the .ics(-link) and select "save as..." to save the .ics somewhere on your machine - in TB with Lightning select "Events and Tasks" -> "Import" and point to the stored .ics Done.
see my comment #19. I've found that some mail clients (macs usually - send an ics file that isn't identified by thunderbird) - then I end up with an ics file that I can't seem to do anything with easily. - I want lightning to pick this up. I understand there are complexities, but there must be a happy compromise RE comment 23 Done. Easy? - try and explain this to a customer. Cumbersome to a user = they won't use it. Answer: give up on Lightning and recommend they use outl$$k - these issues are more important than many people realise I'm afraid that these days, Calendar entries need to be a one click item. (in emails, on your file system, or in websites) - two click at most. right click, save here, option a,b,c click here, do that... simple.? NOT simple enough to your average user I would like to, but I cannot offer this to our customers until TB and Lightning improves its integration with calendar ics files. Integration with Outlook seems to be ~OK, but ics files from outlook for mac or macs in general still needs some work. Improving ics file handling would help alot.
I think ICS should be as follow: 1. User doubleclick .isc file 2. TB opens 3. - If only one calendar is in TB add the event to that calendar - If more than one calendar exists, ask to user to which calendar it should be added I don't see why something else should happen....
I agree with André.
(In reply to haydnlowe from comment #24) > RE comment 23 > > Done. Easy? - try and explain this to a customer. Cumbersome to a user = > they won't use it. No, certainly not. I never said it was easy. But a lot less painful than what comment #22 describes.
"A lot less painful"? This is typical of a techie attitude that condemns products. What's needed here is simple, seamless handling of calendar files. How it should work has been described by several commenters here. It's not adding any value to make comments amounting to "Here's another way to do it, it only required 7 steps, not 12!"
"It's not adding any value to make comments amounting to "Here's another way to do it, it only required 7 steps, not 12!"" I recently switched from Outlook to Thunderbird and was trying to figure out how to use the ics file. This page was the first result on google but I was a bit dismayed to find out this has not been fixed. I was happy to see the work around provided by Marcel. I DID add value and was very helpful. At least to me it was. And it was certainly way more valuable than your worthless post. Marcel, don't let idiots keep you from posting helpful suggestions here.
(In reply to Kirby from comment #29) > Marcel, don't let idiots keep you from posting helpful suggestions here. No worries. I care very little about people who intentionally or unintentionally misinterpret my clear statements. Doesn't "It's cumbersome enough but not nearly as cumbersome as described in comment #22" and "I never said it was easy. But a lot less painful than what comment #22 describes" make it clear that I'm everything but pleased with how one currently has to work around the issue? It certainly does.

A clever way is to right click in the mail content then select Convert > Event.
No way to import directly from shell like: thunderbird -event file.ics ?
Actually it is not *that* user friendly. But the worst thing is that Thunderbird don't show me the .ics file, I just have a message : "This message contains an event"
I've tried this under kubuntu, but no luck: http://superuser.com/questions/382022/how-do-i-get-thunderbird-to-open-an-ics-attachment-directly-in-lightnings-calen OPTION 1: 1. Open the "Today Pane" ie. the Events panel on the right hand side next to the email list. 2. Drag&Drop the ics-file onto that pane. RESULT: does nothing for me. OPTION 2: 1. Convert to -> Event RESULT: doesn't work, because it doesn't show / read the info from the .ics file so I have no idea for when the invitation was. +1 for comment #33 or any solution that doesn't involve saving the file out, and then importing the ics into the calendar.
Here's a workaround to mail yourself the file easily. Create a shell script that takes a filename as an argument, and do something like: mutt email@example.com -s "ICS event mail" -a /path/filename.ics < ./default_ics_message.txt ...with the filename being the argument for the file obviously. Then a right-click on the file and open it with the script, and when the mail arrives you should be able to jsut accept the event. I had to do this because .ics files opened with https://addons.mozilla.org/en-us/thunderbird/addon/lookout/ aren't seen by the calendar. I do have a problem with the charset, which is set to en_DK.utf-8 but umlauts get killed anyway. mutt -e to set the charset might work (need to test), see http://stackoverflow.com/questions/6805783/send-html-page-as-email-using-mutt
Using Thunderbird 17.04 the method where you drag the .ics file into the Events Panel works. comment#35: > OPTION 1: > 1. Open the "Today Pane" ie. the Events panel on the right hand side next > to the email list. > 2. Drag&Drop the ics-file onto that pane. > RESULT: does nothing for me.

[...] Could you please then do the easy part? I'd do it myself but I'm little acquainted on the Mozilla patch process. We can leave the hard part for later, if ever, and/or give some instructions to the user on how to register with the OS manually.
(In reply to David Rees from comment #8) > Four years old and 31 votes, yet no movement. Sigh. 6 years old and over 100 votes, yet no movement, Sigh. Ps I am trying to sort something out for someone, and all we can get is the body_part_1.ics. Dragging into the event panel does not work for me on Thunderbird 24. I can not get an import calendar ( I am using a calDav calendar tried creating a local calendar) All I can do is create a new calendar with the .ics file not much use. Naturally the calendar shows up perfectly in the users outlook and since it is from our main global client, we can not ask them to stop using exchange. Finally found the menu item Menu (thing on right hand side) Events and Tasks (not File which allows you to create a new calendar) Import ... Select the file to import Time wasted about 6 hours so far
As for the moment (TB 25, Lightning 2.7b1) I can't even import .ics files over the "Events and Tasks" -> "Import" menu. I tried two different events, one wouldn't raise an error but would not import either (just nothing), the other event triggered Server Error 412 on my CalDAV-Server (Davical). dragging the ics file in the event panel doesn't work for me either. I don't agree with cs's choice of words (comment #28) but I think he's right that opening ics-files is something users encounter more and more often and it should be as smooth as an experience as possible.
Hi all, I had the same problem too. My colleague using a Mac with Outlook sent me ics files. I found out that Outlook for Mac is using a line inside the ics file which seems not be allowed. The line was: X-ENTOURAGE_UUID:2AC6BAE8-F948-473D-816F-6F6C75860CEE When I saved the ics on my desktop, opened it with an editor, deleted the line a dragged the ics file to my calendar it worked well.
This issue is an evidence of incapability of open source development. Mozilla claims there is nothing left to be developed for an email client.... but this piddling issue is not yet solved... after more then 7 years that I reported it. What a shame. At least it gives me something to laugh about every time I still receive an email somebody commenting on it....

Just opening a feature request won't guarantee you that features will get done: start a bounty, help developers in getting resources or learn to code and implement this yourself. Whining on a bugzilla thread will only annoy developers and spam some innocent people, so please don't do it. That being said, this would be a nice feature to have indeed, developers is there anything we can do to support you?
I'm sorry I can't offer immediate help right now, but I'd be happy to mentor anyone willing to fix this bug.

It should be how Mozilla works. Mozilla is currently begging for donations on its Google homepage, even though it had a net income of US$21.6 million in 2011 (source: Wikipedia), 600+ employees (source: Wikipedia) to develop its small handful of applications and a huge, expensive headquarters in the heart of silicon valley, just down the road from Google's HQ (source: Google Maps). Conversely, many of us have full-time jobs, give our work voluntarily to the community, deal with bugs reported to us in a timely fashion and thank our users for their efforts in reporting them to us. Forget bounty: Mozilla has enough Bounty to sink an armada. What it needs to do now is adequately maintain its products. Nuff said.
Sorry, this is not the forum for governance discussions. Please understand that Lightning is a community project which is supported by Mozilla with a certain amount of release engineering and hosting only. We do not receive money from any of the donation runs Mozilla is doing and I am doing a large part of the maintenance myself. Money is not the solution here, we need a strong community to support and contribute to Lightning. Following the Mozilla spirit, Lightning is a good example on how every individual can make a difference. I understand you want this bug fixed, but this is not about maintenance, but about adding new features.
I wish there was a fund reserved only for lightning development that we could donate funds to. Since this is a community project as stated above that would feel much better than donating money to Mozilla and having no idea if the funds go to the "right" project.
(In reply to Philipp Kewisch [:Fallen] from comment #46) Thanks for explaining, Philipp. That's very helpful information for us. I don't think anybody who is querying this issue believes developers of Lightning are at fault; and we must thank you for the development and support you've put into the product from which we all benefit. But I think I must disagree on this point: > Sorry, this is not the forum for governance discussions. This discussion is about solving the problem described in the bug. If the show-stopper is governance, this discussion should be about establishing that (which it's done) and fixing it, in order that the bug is fixed. > Please understand > that Lightning is a community project which is supported by Mozilla with a > certain amount of release engineering and hosting only. We do not receive > money from any of the donation runs Mozilla is doing and I am doing a large > part of the maintenance myself. Money is not the solution here, I would say that money is clearly the solution here: you should be allocated some to improve the product. Lightning is the reason many people use Mozilla Thunderbird. As I mentioned above, a company that has a net income (what would be called 'Profit' in another company) of US$21.6 and massive offices in Silicon Valley can afford to develop its assets, and has a vested interest in doing so. It is morally wrong for a corporation in their position to rely on the generosity of volunteers for a core part of their service offering. There are community projects which rely on voluntary contributions by necessity, but there is no justification for Lightning to be one of them. > I understand you want this bug fixed, but this is not about > maintenance, but about adding new features. I agree. It's about adding new features to keep the product relevant. > we need a > strong community to support and contribute to Lightning. Following the > Mozilla spirit, Lightning is a good example on how every individual can make > a difference. There are different kinds of contribution. Coding is one of them, and not everybody has those particular talents or skill-sets. Reporting bugs (and feature requests) and using a product (especially one from which the [Mozilla] project derives indirect income) are also contributions. Campaigning to Mozilla to fund Lightning properly would also be a contribution, and a valuable one in my view. I think we need some guidance about how (and to whom) to direct such a campaign.
Bugzilla is for technical discussions that are specifically for fixing this bug. The discussion you are bringing up here is very general and could happen on any other bug. Even if there were funds, this is not the first bug I would fix. There are various bugs out there that need to be taken care of to provide stability. Adding a new feature is nice, but if alarms cannot be dismissed in some cases, invitations are not processed correctly or updates are a nightmare, there is no point in double-clicking on an .ics file in the first place. Lightning has always been a community project, so this is nothing new. Other companies have funded Lightning in the past. For a while Mozilla was doing so for one developer. This was connected to Thunderbird being funded, which is no longer in Mozilla's focus. If you can convince Mozilla that Thunderbird is a product that brings Mozilla's mission forward and contributes to the success of the company, then this is a first step to allocating company funds to Lightning. Given their focus on Firefox OS and related technologies, I highly doubt this is going to happen in the near future. This is my last post on this topic on this bug. If you want to further discuss this, please use the newsgroups. https://groups.google.com/forum/#!forum/mozilla.governance would probably be a good start, as your issue is more of a general Mozilla issue. Personally I'd rather see you use the energy to lead QA efforts, manage support or blog about project updates and statistics.
We've gotten a request in Fedora (https://bugzilla.redhat.com/show_bug.cgi?id=1058074) to register thunderbird with lightning as a calendar app. We can certainly do this, but I don't think I want to until it does the right thing when opening a vcal file.
(In reply to slmingol from comment #37) > Using Thunderbird 17.04 the method where you drag the .ics file into the > Events Panel works. It doesn't work in Windows 7 unless you hold down the CTRL key while you drag the .ics file on to the Events panel. It seems to me that the code for opening ICS files is already there, it just needs to be re-jigged so that double clicking an ICS file will open it. Obviously i realise its not going to be that simple to do, but it should be easier than starting from scratch if the code to open the files is there already. > comment#35: > > > OPTION 1: > > 1.

Hi Philipp, I'd be willing to be mentored. Is there anything specific info or pointer? I've tried several times to help but the codebase appears pretty daunting. Thanks Mauro
Hi Mauro, sorry for the delay. I'm happy to hear you would like to work on this bug. Note that a complete solution might not be easy, but we can start with the simple parts. First of all it would be helpful to even allow importing or subscribing to calendar files using the command line. There are two paths to consider when passing a file to Thunderbird/Lightning. It can either be imported (e.g. copied to an existing calendar or a new storage calendar), or it can be subscribed to (e.g using the ics provider, just subscribe to the file so that changes are being made directly in that file). Maybe it would make sense to create an import dialog that explains and provides these two options. We could use it for bug 167255 too, although it doesn't have to be a wizard as mentioned there. When Thunderbird is started with the command line flag, then this dialog would show up and allow to select how to handle the file. Some optimizations can be made, e.g. don't offer subscription if the file is in a temporary directory or Downloads folder. Once we have this, we can go for the next step and figure out how to make Thunderbird (with Lightning) the default application for .ics files. I'd suggest turning this one into a meta bug and filing a new bug that blocks this one to create the dialog. Does that sound like a plan to you? Feel free to ping me on IRC if you have ad-hoc questions.
Is there anything I can do to help getting this problem resolved?
This a problem for me as well.
This bug affect me as well. Please add ability to import ICS files to Thunderbird.
I have the same problem. I get often mails in HTML format and links for ICS file download. In TB, when I click to download those file, TB asks, if it should be opened in "Thunderbird (Mail)" or save it. There are no other options for the application to be opened with. If I choose to open with "Thunderbird (Mail)", then it is being opened as attachment. Instead, TB could have asked, if I would like to import with Lightning or as an attachment. Also, another default application as an option would have been a solution (e.g. "Thunderbird (Lightning)"). I am using Ubuntu 14.04 LTS and have the TB 38.5.1. Workaround is to save the file somewhere and import ICS file, which takes unnecessarily more clicks and temporary files.
It would be very useful indeed.
