I don't have VBox installed and that file is there in my system. xulrunner is what firefox uses for all of its UI and configuration. (at least that is what I know) $ yum deplist firefox | grep xul provider: xulrunner.x86_64 1.9.1-0.20.beta4.fc11 provider: xulrunner.x86_64 1.9.1.9-1.fc11 dependency: libxul.so()(64bit) provider: xulrunner.x86_64 1.9.1-0.20.beta4.fc11 provider: xulrunner.x86_64 1.9.1.9-1.fc11 dependency: xulrunner >= 1.9.1.9 provider: xulrunner.x86_64 1.9.1.9-1.fc11 provider: xulrunner.i586 1.9.1.9-1.fc11 provider: xulrunner.x86_64 1.9.1-0.20.beta4.fc11 provider: xulrunner.x86_64 1.9.1.9-1.fc11 dependency: libxul.so()(64bit) provider: xulrunner.x86_64 1.9.1-0.20.beta4.fc11 provider: xulrunner.x86_64 1.9.1.9-1.fc11 provider: xulrunner.x86_64 1.9.1-0.20.beta4.fc11 provider: xulrunner.i586 1.9.1-0.20.beta4.fc11 >> I don't know what to try next. I have been using fc12 for a long time successfully for quite a while Any help or advice would be appreciated. > > Is it possible for you to check if XPCOM files related from VirtualBox > conflict with Firefox/xulrunner ones?. Maybe something not compatible > from VirtualBox is loaded instead of the right one. > The OP should first try 1. starting firefox in safe mode `firefox -safe-mode' and see whether any of the add-ons are to blame. 2. If that doesn't work, try looking for unreleased lock files for firefox. $ cd ~/.mozilla $ find -type f -name '*lock' If any are found delete them and try again. 3. If none of the above works try creating a new user and start firefox there. And finally if none of the above work appeal to the collective knowledge of the list with the results from the above. > HTH, > > David -- Suvayu Open source is the future.
