I installed Firefox 3 recently the day it was released. It was very stable. I tried RescueTime for the first time a few days after that. I noticed that FF3 started to crash randomly all the time. It even crashed while running in safe mode. Not able to figure out what was causing this, I suspected RescueTime and turned it off. I noticed that FF3 works fine when RT is turned off. This could be a bug with RecueTime. Please have a look at this bug, since it means that I won't try RT until it's fixed.

I'm running FF3 and RescueTime on WinXP (with all recent Service Packs installed). I've noticed this crashing behaviour on both my work PC and laptop, both of which are running the same mix of software.

I've just downloaded rescuetime and installed it, and when I try to run it (with both rescuetime.exe and rescuetimestart.exe) it gives me the same error message:

"Rescuetime has encountered a problem and needs to close. We are sorry for the inconvenience."

I reinstalled it and still the same message. I've looked for a log to send y'all, but I don't have any idea of what to send!

As far as I know, my .net is completely up to date. What version does rescuetime run best on?
