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.

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...
