I've noticed a weird (I suppose Flash related) memory leak when using the new FireFox browser on OSX 10.5. It happens after prolonged viewings of Flash video on the site, so I switched to Safari 4.

The memory leak is no longer an issue, but I cannot stay logged in for very long at all. Sometimes I can stay logged in for an hour and other times I can only stay logged on for seconds.

Any of the other few Mac users on here experiencing this issue?
