This only started happening today. For instance if i have 5 firefox minimized and i go to open a fresh one just to check something real quick along with my new firefox opening all 5 other firefox become un-minimized and my real quick checking just became a task of re-minimizing 5 pages of firefoxes.

This issue can be caused by an extension that isn't working properly.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.

See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.

  • Use "Disable all add-ons" on the Safe mode start window to disable all extensions.
  • Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

>In Firefox 4 Safe mode also disables plugins (Tools > Add-ons > Plugins) and hardware acceleration (Tools > Options > Advanced > General)
