When I wrote v1.12.x I was concentrating on fixing Google's broken Gmail Greasemonkey API rather than the best possible performance. I've gotten reports that Firefox slows or even crashes for some people. I am 99% sure that this is because of the way the new API I wrote checks for Gmail state changes, etc. It currently checks for a change in the main element every .2 seconds, going through and getting the entire main element wrapper all over again. This would indeed cause slower older machines to have a little trouble.

I will be tweaking the new (post v1.12.04) so that it stores references to static document elements the first time it finds them instead of re-searching the entire DOM every time. I will also slow the checks to every .4 or .5 seconds instead of every .2. All of this should help improve performance.

To those of you having trouble with this, sorry about that, and I hope you will bear with me until I can get the next version out.
