You can install Tab Mix Plus Addon and if you change some settings of opening new tabs, it will work with the original google toolbar (of course after you succeed to install and enable the old google toolbar). I have tested it on FIrefox 25 with changing some settings of the Tab Mix Plus after it gave me the same symptoms of yours.

For all who are curious how to make the old google toolbar enabled in recent versions of firefox see this link:
