Chosen solution

That issue can be caused by corrupted cookies.

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"

Thank you very much cor-el. You just save me lots of time looking for the problem myself or deleting FF completely...

Under Tools, Firefox has no entry called "Options"...so this solution doesn't work...

more options

Instead of Tools > Options use:

  • Mac: Firefox > Preferences
  • Linux: Edit > Preferences
  • Windows: Firefox > Options

Press F10 if the menu bar is hidden on Windows and Linux or use "Firefox > Options/Preferences"
