264745 - Navigating using Find Toolbar can cause browser deadlock

Status: RESOLVED WORKSFORME

(Toolkit :: Find Toolbar, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.3) Gecko/20041017 Firefox/1.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.3) Gecko/20041017 Firefox/1.0

As of the nightly from Oct 16, 2004, using the find toolbar (and more
specifically, find as you type) to navigate (i.e., type to select a link and
then press return to follow it) can case the browser to enter a deadlock, where
it uses no CPU and I have to use e.g. the Windows Task Manager to kill it.

Reproducible: Sometimes
Steps to Reproduce:
1. Visit a web page with a few links, preferably where the links take a little
while to load. http://www.mozilla.org/products/firefox/?en-US&act=1 "works" for me.
2. Make sure "Begin finding when you begin typing" is enabled.
3. Type e.g. "Beware" to select a link on the page.
4. Press return, to follow the link.

Actual Results:  
After a short while, the Find Toolbar will time out and close itself. If that
happens while Firefox is still waiting for a reply (I'm not sure about the exact
timing here though), the browser will deadlock. The throbber stops spinning and
the find toolbar doesn't actually disappear. The window close button works, in
that it closes the browser window, but the Firefox process is in fact still
running and has to be killed manually. I can easily reproduce this with a build
from Oct 16 (on a clean, though not freshly created, test profile), but I
haven't been able to reproduce it on an Oct 15 build.


Expected Results:  
The Find toolbar should close and Firefox should continue waiting for/loading
the link.

I can confirm this, but I suppose it is a dupe of
https://bugzilla.mozilla.org/show_bug.cgi?id=264747 .

can you still reproduce the bug with Firefox RC2 ? If not, please resolve it as
worksforme. Thanks
