1107467 - e10s - sometimes input fields autocomplete doesn't work with OmniSidebar and Puzzle Toolbars addons installed

Status: RESOLVED DUPLICATE of bug 1102410

(Firefox :: Extension Compatibility, defect)

Description

[Luís Miguel [:quicksaver] (not reading bugmail)]

Expected: go to facebook.com, and the login field should give you a list of saved logins/emails to use there.

But if I install OmniSidebar (1.5b4: https://addons.mozilla.org/firefox/addon/omnisidebar/versions/) and Puzzle Toolbars (2.0.1b2: https://addons.mozilla.org/firefox/addon/puzzle-toolbars/versions/), after restarting firefox that autocomplete will never appear.

This is not easy to reproduce, I usually need to restart firefox a bunch of times until the autocomplete stops working. But a user of OSB can reproduce the issue much more easily, and with just OSB installed in a clean profile. This is not an issue in non-e10s mode.

I also have no idea what could be causing this from within the add-on, it doesn't touch any input fields at all or cancel any events. https://github.com/Quicksaver/OmniSidebar/blob/master/resource/modules/utils/content.js is loaded in all browser's content processes via the global message manager, and then all these extra scripts are loaded through it: https://github.com/Quicksaver/OmniSidebar/tree/master/resource/modules/content. But because I can't always reproduce this bug, it's very hard to pinpoint exactly when/what is causing it (if it is even any of those scripts...)

BTW, I'm on Windows 7 while the user is on Windows 10.

Thoughts anyone?

The user who first reported this to me did some extra testing with DownthemAll 3.0b5 (DTA) and Adblock Plus 2.6.6.3878 (ADB):

> 1. Disabled all addons except ADB, autocomplete works. Tried
>  restarting browser a few times, autocomplete works.
> 2. Disabled all addons except DTA, autocomplete works. Tried
>  restarting browser a few times, autocomplete works.
> 3. Enabled both ADB and DTA, autocomplete stops working. Tried
>  restarting browser a few times, autocomplete never works.
> 4. Autocomplete works on every restart with all addons disabled.

> Adblock together with Omnisidebar breaks autocomplete. If I run them
> individually autocomplete works fine.
> This is just weird…

This is very similar to what I can reproduce on my side. I'm starting to strongly doubt this is related to the add-ons themselves (or at least that they're the absolute cause).

I'm not sure the summary should limit this bug to only those add-ons, as both me and another user could reproduce the issue with only AdBlock Plus and DownThemAll add-ons enabled (although I can't trigger the bug at all today, no matter what add-on combination I use... I wish I had better STR...)

Hey Quicksaver - I'm pretty sure this got fixed with bug 1102410 - can you confirm that this is fixed in a recent Nightly?

That's probably the reason for my comment 2 then. I've already e-mailed the other user who first reported this to me, and who could also reproduce this more faithfully, for confirmation. I'll post here as soon as he replies and I'll close the bug if he confirms it as well.

The other user confirmed to me everything is fine now as well.
