1027967 - [e10s] "Cloud to Butt Plus" addon doesn't replace text and also causes 10-second browser hangs on every page load

Status: RESOLVED WORKSFORME

(Core :: General, defect)

Description

[Chris Peterson [:cpeterson]]

"Cloud To Butt" is a simple addon that changes the world "cloud" with "butt" on web pages. It doesn't work in e10s because it can't access the page content from the chrome process.

hi Danodemano, 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:

I think the page hangs are a regression.

I bisected the hang regression to Nightly build 2014-07-16:

Bill: in that regression range, do you think this hang is most likely to be caused by your add-on interposition (bug 1017323), your add-on shims (bug 1031609), or the Add-on SDK update (bug 1037374)?

I just tested cloud to butt and it works for me. It is very slow, but this is expected as it traverses the entire DOM. I'm going to close this bug.
