Firefox freezes when parsing invalid HTML. I came across this bug using the
mangle.cgi script. I'll attach a testcase in a minute.

The "freezeng" testcase WFM with both fresh trunk and 1.7.x builds (20041024) on
Windows ME.

Most probably it was fixed by the mozilla_die1 fix for bug 264956. 

I'm not marking WORKSFORME yet, until someone using WinXP confirms WFM.

Reporter, do you use the latest Java? Do you use extensions?

WFM with Mozilla/5.0 (Windows; U; Win 9x 4.90; en-US; rv:1.7.3) Gecko/20041024
Firefox/1.0.
Java 1.4.2_06, Windows ME.

I'm not the reporter but I strongly doubt this is a Java bug.

Comment 7

[Pavel Penaz]

Oops sorry, I didn't try this with a new profile. It seems Adblock is
responsible for this freeze, with Adblock disabled the testcase does not crash.

Comment 8

[Jacek Piskozub]

OK. Marking then as INVALID per comment 7 by the reporter.

Comment 9

[Robert Parenton]

Adblock exposes a Java bug that is fixed in Java 1.5.0 that causes hangs.

Comment 10

[Jacek Piskozub]

Robert: I have Java 1.4.2_06 and no hang on three new different mozilla.org
products.

Comment 11

[Robert Parenton]

I'm not saying that was for the cause, but Adblock does expose some Java bugs
you don't normally see that were fixed in 1.5.0.

Comment 12

[Jacek Piskozub]

OK. So maybe they were fixed in 1.4.2_06, too. Butbthat still does not make it a
mozilla.org bug.
