Also the "Subscribe to this feed using" dropdown doesn't really work.

ABout to file the same so confirming for Win 7, 32 bit. Occurs on Aurora 44 and Aurora/Beta 43, NOT on 42 and 41. Confirmed by others on Win 8.1 32 bit and OS X, reported as working though on Win 10 64 bit.

STR
1. Visit a website that has an ability to add an RSS feed, like http://www.theregister.co.uk/.
2. Click the RSS icon (if placed on a toolbar or elsewhere) or click  "Subscribe to this page" in the Bookmarks menu.
3. Click the "Subscribe now" button on the resulting page.

Expected results:
The ususal "Subscribe with Live Bookmark" dialog appears and user can add the feed.

Actual results:
Nothing happens, Browser Console shows error message above.

I have a vague recollection of Gijs spotting a bug in this code lately, so perhaps this can be duped somewhere?

This really needs to be a separate bug - the original bug is about e10s on Nightly, which doesn't apply to 43. Can you file one? And can you clarify what settings you have for subscribing (ie what is the default handler that "Subscribe now" would use) and/or provide steps from a clean profile?

That was bug 1228282 but comment #2 sounds quite different - it sounds like the UI otherwise shows the feed normally and works...

Per comment #0 this (the e10s issue) is bug 1109714. I fixed a small bit of the e10s stuff for the feed UI in bug 1183296, but not the subscription.

Ok, talked this over on IRC and it turned out to be caused by enabled e10s (default for clean profile, apparently), so the same bug. Thanks and sorry for confusion. ;)
