All search options and the ability to add/remove/edit and get more disappeared. I uninstalled Firefox for politcal reasons in April, then reinstalled it (after a bit of research convinced me my protest was better aimed elsewhere.) The search bar failed to work. These all failed: > sudo apt-get remove firefox > sudo apt-get install firefox > sudo dpkg-reconfigure firefox > rm -Rvf ~/mozilla/firefox* menu-->help-->troubleshooting [reset Firefox] nor [open profile directory] SOLUTION: When searching for version numbers in dpkg, I noticed two packages for firefox > dpkg -l | grep firefox ii firefox 29.0.1 amd64 The Firefox web browser rc firefox-solydxk-adjustments 29.0.1 all Firefox adjustments for SolydXK > man dpkg confirmed my suspicion that the solydxk tweaks to firefox may have been broken by removing and installing firefox. (rc indicated neither properly installed, nor uninstalled.) > sudo apt-get remove firefox-solydxk-adjustments > sudo apt-get install firefox-solydxk-adjustments Everythings working now. dpkg shows both packages installed correctly. > dpkg -l | grep firefox ii firefox 29.0.1 amd64 The Firefox web browser ii firefox-solydxk-adjustments 29.0.1 all Firefox adjustments for SolydXK I don't know how many Debian forks (Mint, Solyd, Ubuntu, Librenet, etc) might be similarly affected, but I thought I'd get this out there since I know at least one Mint user has seen it this past March.
