when i try to open up a new tab with any method crtl-T or go into the file and click for a new tab or just clicking the + sign on the tabs part all do nothing. it seems like this  has started to occur after the recent patch. but the tabs will still work if i use crtl-link so by clicking on a link with ctrl pressed a new tab will open, other than that nothing else i have found to be wrong.

Works for me on Mozilla/5.0 (Windows NT 6.1; rv:2.2a1pre) Gecko/20110331 Firefox/4.2a1pre.

You should install the latest version of Firefox:

Try using an empty testing profile. (Don't install any addons into it)

Try disabling all your add-on until you find the culprit!

Based on comment 3, this is most likely an add-on bug.

found that after disabling some addons the issue is resolved.

so something from maybe download managers stuffing up the program.
