Firefox stops upload or download until mouse moves

FF7.0.1 on Win7 Pro-64 Another strange behaviour: sometimes FF stops transporting (uploading or downloading) until mouse is moved.

Very strange is, that it will do to move the mouse hovering over any FF window or FF download window, even WHILE ANOTHER (non-FF-)WINDOW IS THE ACTIVE WINDOW and in front of a FF window.

This doesn't depend on specific sites and happens on different sites. And it happens only once in a while, once-twice-three times a day.

Any idea???

Chosen solution

In FF 7.0.1 that bug/behaviour shows up with hardware acceleration ON and OFF - no difference. Now - since two days with FF 8.0 - downloads seem to run as awaited, without stops. I'll test a couple of days, and if this issue is disappeared I'll mark this thread as solved.

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 (safe mode, new profile) already, but didn't get any solution.

Thanks for that new idea: I will deactivate hardware acceleration. So, I got new hope ... ;-)
