Was wondering if anyone here uses grease monkey, primarily using Firefox. I have been running scripts on Firefox using grease monkey and it will crash on me....either Firefox will crash but will somewhat continue to work..ie : downloads will finish and I can move other windows around, the windows in or out of the screen can be moved about via track-pad...and then the whole computer will crash OR it just crashes and gives me a message in three languages to hard boot my computer. When I reboot I get one of those kernel messages. What kind of damage is done to the hard drive from doing hard boots? Using Firefox 5.0 and mac osx 10.5.8. If anyone body knows anything about this and could lend some advice, that would be tops. Thanks.
