My sleep timer (for long running Flash streams)
# wait 1 hour kill flash turn off LCD
sleep 3600; killall npviewer.bin; xset dpms force standbyI restart FF every week or so to keep its memory usage down. I typically have 30-50 tabs open at a time. Is it because I use flashblock?
I actually had a lot more problems with the nspluginwrapper and 32-bit Flash in a 64 bit Firefox (black box after one or two uses of Flash) than I do with the 64-bit Flash build.
It's, admittedly, gotten a lot better over the years, and the 64-bit troubles really only lasted for about 1.5 years (between the time when I moved to 64 bit OS and Adobe released a mostly working 64 bit Flash build; I used a 32 bit Firefox for most of that time). But, it's still pretty common for Flash to cause issues. Going to full screen mode would instantly kill Firefox until just a few weeks ago...and even now, there's no real point to going full screen since it'll be choppy and sluggish, anyway. (And it can't just be the scheduler or the video drivers, since VLC and other media players can do high def full screen without issue.)
Seems to work on my machine, for the most part.
