Breaking too much of the site. Media doesn't load for the most part. I will just use Facebook in a virtual machine from here on in.

The the first time use all fine. Now is impossible surf into de FB platform w/ this ext enable. Very slow reponse, page not load completly, need hit f5 over 10 time for get page full loaded. If I disable this etx. FB run perfect. But w/out isolating :(

Please, fix this issue.

big likeeee. very gooooood. thanks

No settings or temporary disable available. Wrecks every page with an embedded instagram post - wish I could allow instagram on a temporary basis where required. It's a heavy and painful app and the site management feature is cumbersome to tweak. This is a pretty painful add on by Mozilla - as a long time firefox user this puts me off using your browser actually.

I love the spirit of this extension - but after extensive use, it appears to be the root cause of a number of frustrating Firefox issues in daily life: gmail (oops error 1) in persistent tab, loss of the ability to use search engines within the navigation bar (ie. searches stop executing), loss of website navigation in the navigation bar (cannot resolve DNS name, as if the GET method is interrupted).

Removing this extension resolves all of the above issues, I would be an avid user if it didn't come at the expense of FF stability.
