I get this JS error when changing pages (any page almost) and it doesnt matter if FB is open or not: evalInSandbox:Error: Permission denied for <https://facebook.com> to create wrapper for object of class UnnamedClass
It is followed by a further JS error: Error: Permission denied for <https://facebook.com> to create wrapper for object of class UnnamedClass
What is going on?
Solved! Go to Solution.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
Yeah, the problem stopped under "restart with extensions disabled" so I went to help/troubleshooting information/reset and it reloaded with all my favourites, history etc intact. Thanks a lot
I started getting these two errors immediately with the 22.0 upgrade. I am also running NoScript 126.96.36.199 (auto-upgraded simultaneously with Firefox) and SocialFixer; but the latter should only run if I'm on a Facebook page. These errors happen on lots of pages. They stopped when I blocked "Facebook Connect" and "Facebook Social Plugins" in Ghostery.
The problem went away when I upgraded SocialFixer (and Ghostery, which was another automatic upgrade). Between auto-upgrades of add-ons and FireFox itself, it's hard sometimes to maintain control of what changes are related to what possible new problxxxx features. :-)
Case closed (for me)
The solution to fix this bug caused by Mozilla Firefox 22.0 update, you simply upgrade Social Fixer here: http://socialfixer.com/blog/category/releasenotes/
