455906 - Support severities for blocklist entries

Status: VERIFIED FIXED

(Toolkit :: Add-ons Manager, defect)

Description

[Dave Townsend [:mossop]]

The add-on blocklist service needs to support the concept of severities for blocks and allow for customising what level is a hard block and what is a warning.

Comment 1

[Dave Townsend [:mossop]]

First round of this patch is on its way and will cover notification when the blocklist is updated for plugins and add-ons and notification during installation of xpis.

Plugin detection and add-ons detected during startup will not have any notification in the first patch, instead those that are blocked above the threshold will be app disabled, the others that are still listed in the blocklist will be disabled but can be re-enabled later by the user.

Screenshots for UI review to follow...

I need a skim over the words used in the example screenshots, my wording is probably not right, trying to clarify the difference between the soft and hard block to the user is not easy.

User attempts to install an xpi that is soft blocked

Shouldn't the default button be cancel since we are recommending not to install soft blocked add-ons?

Comment 10

[Jennifer Morrow [:Boriss] (UX)]

These look pretty good.  I had a few suggestions, which mainly attempt to be more consistent with our language and description to the user of what's going on.

1. New items have been hard blocked

In this screenshot, I think it's a bit unclear whether the the user is disabling the add-ons by restarting, or whether they have already been disabled.  The texts says they have "now been disabled," and the text asks the user to "disable and restart."

Mossop, have these hard-block addons been disabled at the point the user sees this message, or are they disabled at the next restart?  If the former, the message should be more informative - telling the user what has happened and clicking OK.  If the latter, then even if the user dismisses this message the add-ons will still be disabled at the next restart - that's more of a "later" than "cancel," which suggests the user is canceling the block itself.  I'd change the title of this window based on which one is the case as well.

2. New items have been soft-blocked

The language we're using to describe soft-block addons here is inconsistent.  We haven't verified them as dangerous, so my though is that we should be steering more towards they "may be a security risk" than they are "dangerous add-ons."  I would change the text to "It is highly recommended that you restart with these add-ons disabled for your protection."  Would change title to: "Warning: Add-ons may be instable or insecure."

3. Some soft-block, some hard-block

As with #2 above, I'd change text to:  "The add-ons that have been verified as security threats have been blocked.  It is highly recommended that you restart with the other add-ons disabled for your protection."  Would change title to "Warning: Add-ons may be instable or insecure."

4. Soft-block install

Would change title to: "Warning: Add-on may be insecure or unstable"

5. Hard-block install

Would change title to: Warning: Add-on cannot be installed."

You must restart for them to be properly unloaded and so the user be safe. Once this dialog appears they have been marked to never load again but they remain in memory till the next time Firefox is closed.

I'm a little wary of just describing things as potential security risks. We use the blocklist to cover both security and stability issues, there isn't one word to describe that I think. I also don't think we will be adding things to the blocklist unless we have verified them as a problem. Another problem is that the user can change what level the block becomes soft or hard, meaning the specific issue with an add-on could be different.

These titles feel very inconsistent with what we use elsewhere in the product to me.

Comment 12

[Dave Townsend [:mossop]]

Attachment: patch rev 1

Still need to do further revisions on the strings but that shouldn't stop us getting the code reviewed and it's not the smallest patch in the world...

There are a couple of interface changes to note. nsIBlocklistService has additive changes and shouldn't break any existing js users. nsIExtensionManager has a breaking change, however the method removed should never be getting called by anyone. If that is a real problem though we can just leave it in and make it do nothing.

There will probably need to be a change to the blocklist url, that will come when the server side is updated.

I've created the new blocklist.xul UI for the notification, list.xul was getting too overloaded for it to make sense anymore.

nsIBlocklistService.idl has been moved to the gecko tier to make it visible to the plugin host (final location still to be determined). This allows the plugin host to check for blocklisting when it detects new plugins as opposed to the blocklist having to go through the entire list whenever it changes.

Updated the test for bug 455906 to also cover notification for plugins, and added a test for the new notifications including blocking and warning.

jst, can you review the changes to nsPluginHostImpl.cpp. Also bsmedberg said you might have a better idea of where to put nsIBlocklistService.idl?

Comment 14

[Jennifer Morrow [:Boriss] (UX)]

Thanks for the helpful clarifications, Mossop.

1. New Items have been hard blocked

The language regarding whether or not the add-ons have been blocked is still a bit confusing.  How about for the text under the list:

"The add-ons that have been verified as security risks have been blocked, but a restart is required to remove them completely."

Button: 

"Remove Add-ons and Restart Minefield"

2. New items have been soft-blocked.

Mossop said that soft-blocks are for verified problems, not just potential risks, so I agree the language should be stronger. Only potential problem with the current form is that "the dangerous add-ons" seems to imply a subset of those listed in the box.  And, we've already said that they may be unstable or insecure (above the box)  So, how about for text under the list:

"For your protection, it is highly recommended that you restart with these add-ons disabled."

3. Some hard, some soft

To be consistent with above:

"The add-ons that have been verified as security risks have been blocked.  For your protection, it is highly recommended that you restart with the other add-ons disabled."

4. - 5. Soft & hard block install

After looking through Firefox's other error messages, the language in these in their current form looks good!

> Button:

This isn't really appropriate since we aren't removing the add-ons we are simply blocking them from loading. They will still appear in the add-ons manager and the user can later update to a new stable version.

Fixing up the patch for the other bits now.

Comment 16

[Dave Townsend [:mossop]]

I'm also going to add a warning in the add-ons manager for items that have been warned about: "This add-on may expose you to security risks."

Comment 17

[Jennifer Morrow [:Boriss] (UX)]

Re Comment 15: 

Fair enough.  How about:

"The add-ons that have been verified as security risks have been blocked, but a
restart is required to disable them completely."

Button: 

"Disable Add-ons and Restart Minefield"

Updated screenshots for the previous views above, these should be good to go now I assume. This is the warning in the add-ons manager that hopefully will notify people that they shouldn't be using certain add-ons.

Slightly better view. The warning displays even when the item is unselected to indicate to the user that they are running with something that may be dangerous

Add-ons manager warning when unselected

One possible way to draw attention besides the already overloaded exclamation point (which is really to draw attention to there being additional info) is to use a different background / text color for add-ons in this state... just a thought.

Also, did you intentionally make the text right align as in the screenshot?

I'll chat with Boriss about this since we have all sorts of different ways we want to draw attention now and she has already been thinking about some of them. I think for now this will probably do but if something good comes up I'll add it in.

> Also, did you intentionally make the text right align as in the screenshot?

That is how those statuses have always displayed on mac

Comment 27

[Jennifer Morrow [:Boriss] (UX)]

These all look good, let's push them out.  

Re Comment 26 - I do think there's better ways to highlight add-ons in this list, but since this is already standard perhaps we should deal with this in another bug or overhaul it completely when we fix the add-on manager.

I'm surprised there isn't a bug on this... they should all be left aligned and there should be an exclamation point image to the left (red for issues such as blocklist, incompatible, etc. and green for info such as update available).

Sorry I can add the exclamation point to the warning items, I hadn't noticed it wasn't there. I'll try to figure out where the right align came from

Comment 30

[Dave Townsend [:mossop]]

Attachment: patch rev 3

Adds the red notification for the warning state.

The right alignment on mac came from bug 397723, specifically http://bonsai.mozilla.org/cvsview2.cgi?diff_mode=context&whitespace_mode=show&root=/cvsroot&subdir=mozilla/toolkit/themes/pinstripe/mozapps/extensions&command=DIFF_FRAMESET&file=extensions.css&rev2=1.33&rev1=1.32

I'll catch up with Boriss later and see what she thinks about that, I'll file it separately if it warrants a change.

"expose you" seems wrong though it may be appropriate since using you may indicate to the user the importance of this. "This add-on" seems somewhat superfluous in that all other messages within the add-on don't use "This add-on" since it is obvious in order to save space. I'm a tad concerned about how elsewhere stability and security problems is called out and that here it only states "security risks" since if it is important to call out both elsewhere then it should be just as important to call out both here.
I'm not happy with it but it is a start:
Known to cause security or stability problems.

Can you provide a screenshots of the case where the add-on is disabled and selected / unselected to the blocklisted.label is also shown?

Attachment: selected disabled add-on with warning

Currently it still displays the warning message even when disabled. Perhaps a better option there might be to hide the warning message but display the warning dialog when they try to enable the same as when they install? Or maybe only the warning on selection when disabled.

Hardcoding the color will cause problems with custom themes (in this case if my list background color is red then the text won't be displayed
Also, this appears in blocklist.css and the class blockedLabel is only used in extensions.xml which does not include blocklist.css.

What do you think about going with blocklistedhard and blocklistedsoft instead of blocklisted and warning? My concern is that warning is too generic and can be applied to other things.

I see now that it is getting the blocklist.css from blocklist.xul which though somewhat confusing is ok. The comment regarding color still stands

do we really want to have an IDL that knows about plugins, app names, toolkit names in xpcom/system? wouldn't /toolkit be more appropriate?

The plugin host cannot use it if it is in toolkit. As I've stated I'm open to better suggestions for where to put it but it must be in the main build tier.

A note describing what this pref does would be a good thing.
Also, severity doesn't describe the purpose very well and elsewhere the term level is used.

Would it be worthwhile to change this so it has an includeDisabled param? If so, how about naming it getBlocklistedItems and updating the description accordingly?
If not, I think getNewBlocklistedItems is a better name though I'm fine with it as is.

Another thing that concerns me is that typically getETC methods don't perform additional actions such as enable / disable items as this does.

I was going for matching the add-ons manager UI. On OSX we increase the font size. Elsewhere we bold the name. I've updated to match.

Yeah this is annoying, gone with bold italics which stands out ok though not great.

I've updated everywhere to use the soft term as appropriate.

I'm not sure it is worth it. Really I'd prefer to get rid of this method, it only exists because the blocklist service can't get what it needs without learning RDF which I don't want to do. I've renamed it and added a note to the comment that people shouldn't be using it

Yeah I was trying to differentiate between EM items and plugins, probably not all that worth it.

Hopefully we should never hit it, only if someone were to do something weird with the window I think, but there is no harm in adding it.

I'll have to see what that does. I'm a bit wary that we might start making changes to extensions.css not realising they impact the blocklist dialog too. As far as I understand it the extension.css inclusion in extensions.xml would only affect the bindings. I might be wrong there though.

Yeah that isn't ideal. Not many non-get methods return things though. Maybe |updateAndReturnBlocklistedItems| though it's a bit long?

I'm fine with updateAndGetNewBlocklistedItems or just getNewBlocklistItems with a prominent note in the idl that states specifically what happens to the new blocklisted items when calling this method.

softBlocklisted.label is the only string with the form "security or stability", all the other strings have "stability or security". Maybe it could make sense to have uniformity across all strings.

Attachment: test blocklist

(In reply to comment #59)
> Dave, do you have any tests that you can attach here that i can verify by hand?
>  Thanks

Sorry forgot to add this. This is the basic test I was developing with. It includes extensions:

DOM Inspector at severity 3
Storage Explorer at severity 3
Nightly Tester Tools at severity 2
Fire Gestures at severity 1

Also plugins:

Anything with "DivX" in the name at severity 3
Anything with "Silverlight" in the name at severity 3
Anything with "QuickTime" in the name at severity 2
Anything with "Shockwave" in the name at severity 1

By default anything at a severity lower than 2 will only be warned about, equal to or above will be blocked, but this is controlled with the extensions.blocklist.level preference. You can just set extensions.blocklist.url to the url of this attachment and update the blocklist in the normal way. When it is updated, you should be able to adjust extensions.blocklist.level and extensions.blocklist.enabled and it should automatically update the state of items.

One issue I am aware of is that if the add-ons manager is opened when the blocklist updates it often won't display the restart message as necessary, reopening the add-ons manager would solve that. This is an old issue though.

I should add that if needs be I can put together a blocklist the blocks any particular items you like for testing purposes, just let me know what you need.

Thanks Dave.  question: does blocklisting severity levels affect the versions of the plugins?  or as long as its a quicktime plugin severity 2 (using your example), all versions of quicktime will be affected?

The simple test blocklist I have there will block any of those add-ons regardless of the version. We can block different versions of a single add-on at different severities though if we choose.

Comment 64

Attachment: Incompatible Extension Screenshot

I'm Unsure how to trigger the hard block dialog from comment #50.

I have set the blocklist pointed to the testcase in comment #60, and restarted.   i then installed Fire Gestures (sev level 1) and Dom Inspector (sev level 3) from addons manager.

1) Fire Gestures gave me the soft block installation error as expected.   Check.
2) But Dom Inspector gave me the "incompatible extension" with Fx3.1b1 error.   Is that right?  Shouldn't I be expecting to see the Hard Block Error dialog instead?

(FWIW, if the blocklist is not enabled, Dom Inspector installs just fine without an error)   Screenshot of error attached.
