Mulongo oyo etiyamaki na archive. Tuna motuna mosusu soki osengeli na lisalisi

Recently, when I opened a website (any website) with Firefox, it opens, then 'disappears' into the side of my screen. I can't get the webpage to display normally.

After years of problem-free browsing on the same computer, Firefox now opens up to the taskbar, then you can see the page move over to the right of the desktop, then disappear. Cannot get it to display in center of screen as normal. This happened for the first time about a month ago. We uninstalled Firefox, updated to the most recent version and reinstalled. All was well until yesterday. Doing it again. IE works fine.

  • Use Restore or Maximize in the right-click context menu of the Taskbar icon to set focus to the Firefox application if you do not see the Firefox window.
  • Open the system menu via Alt+Space and see if you can move and resize that window.

If that works then close Firefox (File > Exit/Quit) to save that setting.

the suggested solution didn't work for me, I tried both safe mode and manual removal of the localstore.rdf file. I can still only open the FF window as maximized. :(

We tried the suggested too, with no result. Still opens, then you can see it 'shoot over' to the right side of the desktop, where it is irretrievable.

Did you try to open the system menu via Alt+Space after you've set focus to Firefox by right-clicking Firefox on the Taskbar and choosing Restore?

If Firefox is maximized then you first need to un-maximize to be able to make changes to that (hidden) window.
The system emnu should open on a visible position and allow to resize and move that window.
