firebug affects firefox performance? well…duh, i guess.
ive been experiencing a noticeable downturn in firefox performance recently…not only performance, but general experience getting effed up over time and required restarts of the app. tab performance, cursor performance…everything was just out of whack but could be remedied by a restart of the browser.
on a whim i decided to disable firebug and only enable it for specific sites on an as-needed basis. I guess it makes sense, all of the extra stuff it does in with the page cache that things could get out of whack or slow down. Maybe it’s a placebo. Maybe I did something else and its a coincidence.
Any takers?

I had the exact same experience. The slow down only occurred after hours of browsing JavaScript intensive sites, but it was exactly as you describe. Completely disabling Firebug solved it, but only turning it off in the Firebug menu did not.

Yap, I can confirm this, too. With Firebug my Firefox slows down over time. Without Firebug this doesn’t occur.
Typical memory leak behavior really.
