Thread: Buttons from address bar and toolbar vanish in Mozilla

My problem with Mozilla Firefox is all buttons from toolbar and address bar vanish. This started after installing Opera. I able to surf Internet with Mozilla but buttons are not there. So can anyone know why buttons are disappearing? Any help will be appreciated.

I think opera installation is clashing with Mozilla Firefox. All browsers become default browser because of which browsers clash or may be opera has damaged files. So remove opera from PC and then check if Firefox works appropriately or not.

Try and update existing version of browser which is installed on PC. Many times files which are missing from system are replaced in update procedure. To update Mozilla Firefox, start browser and click Help. Choose "Check for Update" option. Now browser checks for all updates which are available for browser. If there is any update, then download and install it. This may solve the problem.
