after uninstalling and reinstalling on windows 8,firefox still only opens on the taskbar where I can view it in thumbnail but when I click on the taskbar firefox icon it will not open up to full desktop view. I know it is open because I can hover over taskbar icon and thumbnail view appears.

hello kuulaa, please try the following while all firefox windows are closed: press windows-key + R and open %appdata%\Mozilla\Firefox\Profiles\. a explorer window should open, in there go into the <randomstring>.default folder, search for a file named localstore.rdf and rename or delete that file.

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

You can use one of these to start Firefox in Safe Mode:

  • On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
  • On Mac, hold down the Options key while starting Firefox
  • Help > Restart with Add-ons Disabled

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window.

Did you try to maximize the Firefox window to see if that make it come in view in case the window is off screen?

You can also try to open the system menu via Alt+Space.
