Firefox Community Forum

I've disabled extensions, changed settings, and reinstalled multiple times, but Firefox won't quit stuttering constantly. Other browsers work fine on my computer, and Firefox doesn't seem to be using much memory.

I have 5 windows open in Firefox, yet only 1 of them is visible/accessible on the Windows Taskbar.

I know there are 5 windows open as Troubleshooting Information reports "Multiprocess Windows: 5/5"

Sometimes when I launch Firefox, the other 4 windows will be visible, and this current one will disappear. If I go to Recently Closed Windows and open that window, it will appear, but the other 4 will be hidden again.

Other times, I will launch Firefox and one window will be invisible, and it won't appear unless I close all the other windows, then it will suddenly appear out of nowhere.

I am having trouble downloading documents. They never finish loading and if they do I cannot download them to a file. Also when I exit firefox it isn't closing correctly. It brings up the last session. It keeps telling me it is still running even though I am exiting.

When I first open Firefox I have noticed the past few days that if I try to click on anything on the menu bar right away I get a not responding error message and I have to end up shutting the program down. If I wait a few minutes the menu bar does work normally.
