I've submitted a few bug reports when Glitch/Firefox starts to hog up obscene amounts of RAM. I have the debug Flash Player installed, so I'm hoping/assuming that my reports would prove helpful in figuring out how and why this is happening.
Should I keep submitting bug reports when this happens, assuming that you're getting valuable information from the debug Flash Player reports? Or should I just knock it off since I've submitted the bug a few times already?
