In the news feed;
User picture thumbnails, album pictures does not enlarge. However, pictures of shared external and internal pages and some external video thumbnails do enlarge. Is this a know bug to be fixed in the new version?

All these three check boxes are checked under the settings:
Popup bigger versions of profile pictures on mouse over
Popup bigger versions of photos on mouse over.
Popup full-sized versions of external images. beta

Versions:
FFixer 2.3.1
Firefox 7.0.1
Greasemonkey 0.9.12

Same goes for me, and has been for awhile now. Pretty annoying since you never know what's going to pop up now until it happens.

You're using old versions of FFixer, Firefox and Greasemonkey.

FFixer Latest: 0.3.1.4 Beta (http://www.code-poet.net/userscripts/beta-versi...)

Firefox Latest: 8.0.1

Greasemonkey Latest: 0.9.13

Updating to the latest FFixer beta should solve your problem. If you're having other problems like the timestamp and etc, you can also refer to this thread: http://userscripts.org/topics/88868
