firebug: awesome tool, high price.
in memory, that is. If you’re using firebug and simply flipped it on for everything (mostly so you could ‘tut-tut’ at the endless js errors of other sites), you are probably restarting firefox at least 5 times a day.
really, it’s worth just whitelisting the sites you’re actively working on. I find firebug indispensable (particularly the DOM Inspector functionality and the ‘Inspect’ button, which lets you *easily* see where CSS elements are coming from and make minor tweaks without reloading) but I’m *still* restarting firefox two to three times a day with just our current site activated for debugging. Previously, when I had everything on, firefox probably had to get restarted once every hour.
Interestingly enough, firefox is able to suck up more memory before it ultimately gets crashy — it’s eating up to 500-600M on my 1G laptop, where with everything enabled in firebug I was usually restarting by the time it ate 300M.
