998078 - [e10s] "StumbleUpon" add-on does not work correctly with e10s enabled

Status: RESOLVED FIXED

(Firefox :: Extension Compatibility, defect)

Description

[Brian Carpenter [:geeknik]]

While playing around w/ e10s in the latest x64 Nightly build, I noticed that the StumbleUpon extension does not work correctly when e10s are enabled. The Stumble! button works (this fetches another website and loads it in the browser), but the rating buttons (thumbs up/thumbs down) do not work. I do not see any errors in the console and I have verified that the ratings do not work by visiting my StumbleUpon profile and checking to see if the sites show up in my list of likes/dislikes.

5 months later and the Stumble! button no longer works. When you click it, the following appears in the Browser Console:

GET https://sb.scorecardresearch.com/p [HTTP/1.1 200 OK 25ms]
StumbleUpon error message:

Kyoki, are you the maintainer of the StumbleUpon add-on? Your add-on does not work with multiprocess Firefox (e10s). If you have any questions about e10s support, just drop by the #e10s IRC channel on irc.mozilla.org. MDN also has a good introduction:

I'm not familiar with Kyoki, but a gentleman named Don is the current maintainer of the StumbleUpon extension for Firefox. FYI, I've already made them aware of the issue a few months ago.

In the most currently Nightly w/ e10s enabled and the Stumble! button works again, but when I click the I like it! button, I see the following:

TypeError: getBrowser(...).docShell is null stumbleuponOverlay.js:14048

The corresponding line: 

var webShell = getBrowser().docShell.QueryInterface(Components.interfaces.nsIDocCharset);

Just trying to keep this bug current. Folks from StumbleUpon should have eyes on this now.

We are beta testing an update for e10s:  https://addons.mozilla.org/en-US/firefox/addon/stumbleupon/?src=ss#install-beta

Looks v4.19b1 has added e10s compatibility and I've tested it and it works, so I'm going to mark this as fixed.
