Similar to bug 370860 but still happening even after that one has been fixed in 18.104.22.168 bug 370860 dealt with a lot of slashes ('////////....') and the URL in question here is a lot of text ('aaaaaa....'). Reported as a crash on Full-Disclosure, but I and several F-D readers only see a CPU spike. http://archives.neohapsis.com/archives/fulldisclosure/2007-05/0005.html Turning off the phishing protection option in prefs makes the problem go away.
Testcase originally from http://www.critical.lt/research/opera_die_happy.html Had to zip the testcase for size, access it using Mozilla browsers as jar:https://bugzilla.mozilla.org/attachment.cgi?id=263384!/opera_die_happy.html
If there's an easy fix and we need a re-spin for some reason it would be worth getting this one into 22.214.171.124. But since there's an easy workaround (turn off phishing protection) and it's just a resource hog and the similar bug 370860 required re-writing JS bits as C++ I don't think this is a true blocker.
I'm indeed seeing a crash, when I'm closing the tab with the long url, I was using a Bon Echo build of 2007-04-27. I'm getting useless talkback ID's, though: Talkback ID: TB31715490M msvcrt.dll + 0x378c0 (0x77c178c0)
I did manage to crash once (TB31715128), which looks like bug 282660.
It's likely that the patch on bug 368998 fixes this performance issue.
On my trunk build, the above jar URL takes about ~5-6 seconds. But you can always make a longer URL and the time is still going to be linear w.r.t. URL length.

that stack would be bug 282660. If it's reproducable, it'd be greatly appreciated if you added some logging and figured out what it means for the script to be null.
bug is fixed in firefox 126.96.36.199 ?
not fixed. Changelog++
Depends on: 368998
Severity: normal → critical
Target Milestone: --- → Firefox 3 M9
Priority: -- → P3
Target Milestone: Firefox 3 M10 → Firefox 3 M11
Is this really still unfixed?
The latest Linux nightly doesn't crash, but it does take a long time and chew up CPU.
Not blocking on this bug for final ship. Would take a safe enough patch if one comes through.

The original test case now returns a 403. When trying to open the jar URL from comment 2, I get: "Unsafe File Type The page you are trying to view cannot be shown because it is contained in a file type that may not be safe to open. Please contact the website owners to inform them of this problem. Please contact the website owners to inform them of this problem." Since it cannot be reproduced anymore, I'll close this bug.
