Created attachment 8857084 [details] Browser Console Error I see an XML Parsing Error: undefined entity location error in the browser console when trying to install.
Vasilica, would it be possible to run mozregression again? The only thing remotely close to addons is: > Kris Maglione — Bug 1335180: Fix race in browser_ext_tabs_reload_bypass_cache. r=mixedpuppy But that just fixes a test (...for webextensions).
(In reply to Mike Taylor [:miketaylr] from comment #2) > Vasilica, would it be possible to run mozregression again? Performed again but I received the same result. That's all I can get from mozregression. The tool stops because there are no more inbound revisions.

Andy, would you be able to find someone to look at the regression range to identify what could have caused an XML Parsing error in an overlay.xul file? Thanks!
I'd rather people focus on WebExtensions, rather than a XUL overlay add-on with that number of users. Is there some reason we should take the time to look at this?
Nope, that's fair.
