Terrible cursor lag with Firefox 12.0
I was holding out with version 3.6, but finally gave in and upgraded to 12.0 last night. MISTAKE. From the moment I did so, I started getting terrible cursor lag--including double images of the cursor, which made it look like each letter was enclosed by 2 cursors (the "old" cursor image on the left, and the new one on the right), like this: |a| This was so distracting it made it difficult to type. The problem has happened on numerous sites, including Google Groups, Facebook and YouTube.

hello, as a first step to diagnose the issue please start firefox in safe mode once and see if the problem is occurring there too - in order to rule out the influence of any addons or hardware acceleration.
Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
It is highly unlikely that my problem is caused by "add-ons or hardware acceleration," because the ONLY thing that changed from one minute to the next is that I upgraded Firefox. I have all the same add-ons I had with 3.6 (except for 2 that were disabled because they're incompatible)--so why would they be causing a problem with 12.0?
I am doubly angry over this, because while I was on this site posting my question, I was INVOLUNTARILY "upgraded" to 13.0, despite the fact that I had unchecked the automatic upgrade option! And I had thought Mozilla was better than the Evil Empire. Clearly I was just being naive.
System Restore, here I come.
well, hardware acceleration wasn't used in firefox 3.6 but is present in current firefox versions - so it might be an issue here, but in order to find that out, it's necessary that you do this basic troubleshooting step...
