Embedded pull-down menues are extremely slow to open since the last update, how do I fix it?
I use a Microsoft mouse, functioning well in other environments, Windows 7 latest update. Using down an up arrows work when I succeed to highlight the menu but sometimes I don't.

You can try to disable hardware acceleration in Firefox.
- Options/Preferences -> General: Performance
remove checkmark: [ ] "Use recommended performance settings"
"Use hardware acceleration when available"
You need to close and restart Firefox after toggling this setting.
You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
No, the error seems to have disappeared. Can I remove the problem permanently?
It could be the work of one of your add-ons. Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)
In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.
Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.
If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.
Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.

Thanks. Had no time to test until today. Turning off hardware aceleration solved the problem. Have not yet checked if there is an update for my graphics hw.
