Chosen solution

Make sure that you do not run Firefox in full screen mode (press F11 or Fn + F11 to toggle; Mac: command+Shift+F).

If the menu bar is hidden then press the F10 key or hold down the Alt key to make the menu bar appear.

Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible: "View > Toolbars"

Can you post a link to a public page that doesn't require authentication (log in) to access it?


Reload web page(s) and bypass the cache.

  • Press and hold Shift and left-click the Reload button.
  • Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
  • Press "Cmd + Shift + R" (MAC)

Clear the cache and the cookies from sites that cause problems.

"Clear the Cache":

  • Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"

"Remove Cookies" from sites causing problems:

  • Tools > Options > Privacy > Cookies: "Show Cookies"

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

I TRIED - NOTHING WORKED

Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)

WHAT IS "R" - THE LETTER R ?

HOW DO I START FIREFOX IN SAFE MODE AS DESCRIBED ABOVE?

more options

If pressing Ctrl and the F5 key didn't help then pressing Ctrl and Shift and the letter "R" won't probably help as well to reload and bypass the cache.

In Firefox 4+ versions you can use one of these to start in Safe mode:

  • Help > Restart with Add-ons Disabled
  • Hold down the Shift key while double clicking the Firefox desktop shortcut (Windows)

Does that only happen on that specific website or do you have similar problems on other sites?
