1. VimFx 0.5.12 from https://addons.mozilla.org/en-US/firefox/addon/vimfx/
2. Change "browser.tabs.remote.autostart" to true and restart Firefox.
3. View a page, e.g. Wikipedia.

In a second or two, Firefox hangs.

When the hang happens, I see the line with "ABORT"; some time later, the rest appears.

"kill -ILL" leaves the "plugin-container" (AKA "Browser") process around.  I had 30 of those piled up.

Thanks, Aleksej. This hang is probably related to or a duplicate of bug 1010737.

Thanks for finding the regression range, Aleksej. There are a few suspicious bugs in that pushlog:

* bug 1037374 - Update Add-on SDK
* bug 1031609 - e10s add-on shim
* bug 1017323 - e10s add-on interposition

Aleksej: does VimFx still hang your browser with e10s enabled?

hi akhodakivskiy, if you have any questions about add-on support for multiprocess Firefox (e10s), just drop by the #e10s IRC channel on irc.mozilla.org. MDN also has a good introduction:

https://developer.mozilla.org/en-US/Add-ons/Working_with_multiprocess_Firefox

Thanks for heads up, I will investigate this.

No, 2014-08-30-03-02-04-mozilla-central-firefox-34.0a1.en-US.linux-x86_64 does not hang.  But VimFx keys do not work.

Just to be clear - the current hanging issue - is it a problem with e10s implementation, or something wrong about the VimFx addon? As I understood there will be backward compatibility for older addons..

Aleksej, thanks for bisecting the hang fix. Nothing in that pushlog range stands out (to me) as an obvious hang fix, but at least the hang is gone. :)

Anton, from Aleksej's comment 8, it sounds like the hang is no longer a problem, but VimFx has some other problems with e10s. We will try to maintain Firefox compatibility for older addons, but many addons will require fixes to work well with e10s.

I'm closing this bug WFM because we've received other VimFx bug reports (like bug 1095748), so presumably those testers' browsers are not hanging. :)
