User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10 (.NET CLR 3.5.30729)

My Browser-Cache setting was 0 MB. I switched it to 10 MB to test something.
I switched it back to 0 MB and Firefox crashed.
When i start it again and want to make the settings back to 0 MB it crashed again.
I can fix this, when i fix this in about:config under browser.cache.disk.capacity manualy (the 10MB are still there). Don't know why this happens, but its the second time that it will be happen.

Thanx for that, this is entirely unrelated to the cache itself, it's a core bug. Punting to XUL for lack of a better place.

Comment 5

[Nochum Sossonko [:Natch]]

What are the steps to reproduce for this bug? Can you tell me exactly where you are changing this setting?

Comment 6

[Achim Töpfl]

I test this on a second pc and its the same there.

Reproduce (in German Version):
1. Go on Extras->Einstellungen->Erweitert
2. Offline-Speicher change from 0 MB to 10 MB and ok them.
3. Go to Extras->Einstellungen->Erweitert
4. Offline-Speicher change from 10 MB to 0 MB and ok them.
5. Crash
6. Restart and do Point 4 again.

Fix:
1. Go in about:config
2. Change browser.cache.disk.capacity to 0 manualy.
3. Not it's under Go on Extras->Einstellungen->Erweitert->Offline-Speicher 0 MB
4. But when you do Step 1-4 again it crash again!

I'll hope you understand my bad english :o)

Fix 3. "Now it's" not "not it's"

I don't have a German version of Firefox, can you translate what those Options are?

[Achim Töpfl]

Don't have the english version.
I'd make a screenshot for you: http://img34.imageshack.us/my.php?image=bugkau.jpg

Where the arrow is, i'd changed the value.
