I get a JavaScript Application error message that appears multiple times on most webpages and I don't know what the problem is.
Here is the error message:
[JavaScript Application]
evalInSandbox:Error: Premission denied for <https://www.facebook.com> to create wrapper for object of class UnnamedClass
The message pops up multiple times whenever I reload certain pages.
The problem does not happen in Safari or Chrome.
I've restarted Firefox but it does not help.
Let me know if there is anything I can do to make the error stop.
Thanks!

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).
- Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.
hello flabs, this is likely caused by an outdated extension. in case you have the social fixer addon installed, please update it to the latest version that is available at http://socialfixer.com/blog/category/releasenotes/.
