On FF10 Beta Channel, OSX 10.7.

Every few seconds the browser completely locks up for about a second, including when I'm doing something as simple as typing into a non-smart textarea. I have about 11 tabs open, and have tried restarting FF multiple times.

The pausing, over a period of 60 seconds, happens about 12 times, and pauses for about 1 second each time.

Going into safe mode and disabling extensions one by one seems to point at Visual Hashing. I assume it's doing something that is causing excess GC or gratuitous event handling.

Until Monday, I didn't have any issues. It seems that the nearest update to the Beta channel initiated this.

Please let me know what I can do, or what I can try, to help debug!
