Firefox 3.0 tends to crash upon Firebug error message

When I load a page and Firebug detects an error (like Javascript variable not defined, syntax error in Javascript, or so), it simulates a breakpoint at that location.

If I overlook this and just try to go on, Firefox seems to crash. The only way to prevent such crashes is first to respond to this simulated breakpoint by clicking on the blue arrow to ignore the breakpoint and proceed running.

If I forget to do this, then FF will soon more or less crash. It seems that in the background Firebug is still waiting for input. If I stop Firefox (by clicking the X in the top-right corner), then I cannot re-start it before first having removed a remaining task (named "Firefox ") from the Windows task list. After I have removed this remaining portion from the task list, I can restart FF and everything seems OK.

(To me it seems that this remaining task named "Firefox" is actually (a part of) Firebug, but I am not sure.)

Version info:
* Firefox 3.0.1 (Dutch localised)
* Firebug 1.2.0b7
* Windows XP Professional SP2.

Firebug is a Firefox add-on (I never heard of it until today). Do you need it? You can always disable it, and see how Firefox works.

 

Of course I can disable it, and I sometimes do. So I can indeed say that I need it.
But it is a good Javascript debugger. Especially the latest version hits on completely unexpected flaws where IE only hangs, or reports "an error" with no further information understandable by normal people like me (maybe a line number that is far off).

The problem I reported seems to have to do with the internal task management (or thread management?) in Firefox. The "remaining task" in the WIndows task manager is named "Firefox ", but I would not be surprised if it actually is a protion of Firebug.

 

Considering that add-ons are not integral part of the browser, anything can happen. I, often, contacted developers of add-ons and themes, and, generally, I got satisfaction. They are not always aware of everything, and they need feedback.
And, yes, what is in the task manager would be called Firefox, as it has incorporated the add0on.
