i guess that the Skype Extension/Plugin for Firefox
That's not a plugin... over to extension-compat for now.
Component: Plug-ins → Extension Compatibility
Product: Core → Firefox
QA Contact: plugins → extension.compatibility
Version: 1.9.1 Branch → 3.6 Branch
This is the Skype web add-on which gets installed into the extension folder of the application directory. Its installation is enabled by default when installing or updating Skype as what I can read from different Skype forums.

Given by the crash reports this crash only occurs for Vista and Windows 7. Windows XP users are not affected.
OS: Windows XP → Windows Vista
The core-counts report in http://people.mozilla.com/crash_analysis/ suggests this is a threadsafety bug:

  SkypeFfComponent.dll@0x440c3|EXCEPTION_ACCESS_VIOLATION (1071 crashes)

(though 6% is a relatively high count for a single core machine).
Looks like this is related to a new version of skype:

... probably one that shipped recently.
This is now the number 2 TopCrasher for Firefox 3.6.  Has Skype been contacted?

I submitted a support request to skype and hope they follow up here in the bug, or contact me.

Isn't SkypeFfComponent.dll the Skype Toolbar? While having a quick search on Google a lot of results point to that piece of Addon. Sadly I wasn't able to download that because of a broken download link.

Marcia, I have seen that the toolbar was installed on the QA machine in the lab which I have prepared with WinDBG. Can you point to the url of the toolbar to download or send me/attach that file?
Hi
It seems this might indeed be due to the Skype extension for Firefox. We are looking into it. 
Can anyone reproduce this problem? Any steps that reliably produces a crash?

Best regards
Peter Kalmström, PM Skype Toolbars, skype: peter.kalmstrom.nu
Peter, can you give me a link where I can download this version of the toolbar? That would help me a lot. I can try to reproduce it afterward.
Hi Henrik,
http://go.skype.com/dc.clicktocall
After some consideration we have found that this bug is actually fixed, but we have yet to release the update. Please let me know if you can reproduce the crash.

Best regards
Peter Kalmström, PM Skype Toolbars, skype: peter.kalmstrom.nu
Peter, I will try to get it reproduced. Btw. is there a download location for the new beta version?
Henrik,
No we currently do not have it available, we should within a few days though.

Peter, this msi installer does not contain the Skype toolbar for Firefox. When I click on change the only toolbar which is shown there is for IE.
#3 top crash in very early firefox 3.6.2 crash data.  Peter, any update on availability?
Hey guys, 


I just reinstalled a fresh version of windows 7, the newest skype client, and the latest version of firefox. 

I used to be having issues with a nvidia driver crashed the FF, since the reformat, i have had 1 firefox crash due to this skype extension. 

When I get home from school today in about 6 hours, I will try reproducing the crash the skype extension creates.
http://crash-stats.mozilla.com/report/index/0225a38d-f1f5-4946-a77e-808402100327

Very wierd, This crash happened right after i restarted my cpu, I stared my eve-online client, and then started firefox, it loaded the default google page, and I clicked on my "myspace" bookmark in the bookmarks tab, the FF client then crashed and submitted the report. 

Before my reformat I had always had trouble with the myspace site causing crashed for some odd reason, this may be unrelated, but I wont rule it out either. 

Will do some more browsing on and off the myspace site and others to try and reproduce again.
Joshua, can you please give me a link from where you have downloaded the Skype toolbar for Firefox? I'm still waiting for an answer from my comment 17.

Henrik,

This extension was automatically installed when I downloaded the skype client. I have just reformatted my computer, I downloaded firefox first then used ff to download skype. It auto installed the toolbar plugin and asked me to restart fire fox.

I hope this helps.

Are you still looking for a copy of the skype client? I am bug report 578206 and have been having this crash quite frequently. I still have a 1.6MB executable in my downloads folder that I downloaded and installed from Skype.

SypeSetup.exe
File Version 4.2.0.155

I have uploaded a copy to one of my webservers. Let me know if you no longer need it, so that I can delete the file from the server.

http://www.theten.co.uk/SkypeSetup.exe
FYI, I just worked with a woman on the phone on this. She's running Win7, Fx 3.6.6 and has version 4.2.0.5198 of the Skype extension installed (she just recently installed skype). She called us because Fx would crash often (but not always) when opening it up from a shortcut on her desktop. The shortcut took her to her MyEbay page FWIW. I looked up her crash reports and they point to this bug. I had her disable the extension (no option to uninstall).
I just experienced this crash on Windows 7, however, I have the latest version of Skype installed (4.2.0.169). I also noticed that it is currently number 2 on the top crashers list for Firefox 3.6.8:

http://crash-stats.mozilla.com/topcrasher/byversion/Firefox/3.6.8

Why is the Skype toolbar still crashing Firefox if the bug has been fixed?
Assignee: nobody → peter.kalmstrom
I looked at a sample of 100 recent crashes.
100% of the crashes are when SkypeFfComponent.dll| version 4.2.0.5016 is around.
a 36% of the crashes are at address 0x10000000 and then there are a variety of other crash addresses.

http://www.skype.com/intl/en-us/get-skype/on-your-computer/windows/ says latest version.

Version 4.2.0.187 File size 18 MB. Official release. Release date: September 6, 2010. File name: SkypeSetup.exe

I'm not sure why the version number is higher than the latest version offered on the site.  Peter, can you comment on that?


I'm pretty our guidance should be for firefox users encountering this crash to update to the latest Skype to fix the crash.   If anyone spots a crash on a the current version offered for download or one later than 4.2.0.5016 please post in the bug.
Internet archive doesn't help to point out when 4.2.0516 would have been offered on the skype site.

http://web.archive.org/web/*/http://www.skype.com/download/skype/windows/

maybe the SkypeFfComponent.dll version and product version can differ.  Can anyone with skype installed report back on the version if SkypeFfComponent.dll when they have the latest product version (4.2.0.187) installed?
Hi, All...

I can tell you that I am running Skype BETA 5.0.0.123 - while there is no issue with Skype itself, these crashes still happen in Firefox.  Now that I know it's related to Skype, I can disable the Skype / Firefox connection - or I can leave it, if it would be good for testing / debugging purposes for someone.

Thanks...

Andy

Still early to tell, but it looks like the soft block is starting to have a positive effect on the daily crash rate.   down from 8000 crashes per day to just under 6000 crashes per day on all skype crashes.  A few things complicate the numbers.  One is that a data migration for the crash system happended on Saturday and we may be missing a few crashes from my data sample there, and second is that most of this is over a weekend when usage and crash reporting is generally lower.   I'll update again in a few days with some more data.
Follow up on https://bugzilla.mozilla.org/show_bug.cgi?id=546632 – we don’t believe there are any bugs in our Skype release that start from 5.0.0.6483 onwards that have resulted in crashes stated above, specifically:

Marking verified for branches since it is now blocked in all versions.
Keywords: verified1.9.1, verified1.9.2
Crash volume has been around 5800 for the last couple of days so the affect of the soft blocking might be diminishing.  Hopefully we will see further declines in the crash rates and I'll update in another few days.

re: comment 42

There is one signature that is exclusively on version 5.0.0.6483

SkypeFfComponent.dll@0x1a260|EXCEPTION_ACCESS_VIOLATION_READ (62 crashes)
    100% (62/62) vs.  13% (22826/175979) {AB2CE124-6272-4b12-94A9-7303C7397BD1}

          0% (0/62) vs.   4% (6590/175979) 5.0.0.6906

The volume on this signature seems to be running 60-100 crashes per day.

And there continues to be crashes showing up on 5.0.0.6778 and 5.0.0.6906
Is 5.0.0.6483 a newer version than 5.0.0.6778 and 5.0.0.6906?

Here is a list of signatures where we see 5.0.0.6778 and 5.0.0.6906 showing up.

I spun off bug 629033 to deal exclusively with crashes that affect 5.0.0.x versions of the toolbar.

We should also spin of remaining bugs that deal with performance issues and hidden installation.  Does anyone know if bugs are on file for those issues?
still very slow progress in reducing the number of daily crashes.  it's inched down from 5800, to 5700, and 5200 crashes in the last few days.

I also checked about how many of these crashes had e-mail address, and it looks like only about 80-90 per day have contact info so it probably doesn't make sense to set up the e-mail auto responder for this one.
Why is this added to blockers? It is not a Firefox bug, but a Skype.
Kev, Boris and the skype team have been working on this.  As of this week all crash bugs are fixed with the latest build of Skype.  We are working with Boris , please let us know if there's someone else at Mozilla we should be working with to close this bug and confirm the fixes.  thanks
Whilst you say the crash bugs are all fixed on 3rd Feb, there were still 49,000 crashes in the last 2 weeks:
https://crash-stats.mozilla.com/report/list?range_value=2&range_unit=weeks&signature=SkypeFfComponent.dll%400x440c3&version=Firefox%3A3.6.13

Is it just a case of people not updating to newer versions of the Skype Firefox toobar? Might putting the toolbar on AMO help make sure that people get updated sooner?

Also, to add to the problems, it would seem that the softblock hasn't done much, since people are just pressing cancel without reading it, which doesn't disable the extension (bug 523784) - and so they aren't even seeing the advice to update their version of Skype on the blocklist info page.
Yes crashes are fixed in latest version. And yes we'd very much like to put the latest toolbar on AMO to force the upgrade.

Ah, this one. I am resolving as works for me since they provided a new version that works. There have been subsequent crashes pop up and we have new bugs logged for those.
