247149 - Browser appears to lock up if too many extensions are installed.

Status: RESOLVED DUPLICATE of bug 245610

(Toolkit :: Add-ons Manager, defect)

Description

[XeRXeS]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040614 Firefox/0.9
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040614 Firefox/0.9

I was installing a variety of extensions for the newly released FF 0.9 (from the
official site, under the verified 0.9 section, to ensure that incompatible
extensions would not cause any problems) and found that once I had installed
around 20 or 21 extensions, the browser would display a "Finalising Extension
Install, this may take a minute.." window, and sit there indefinately. I left my
computer for over an hour to run some errands, and it was still sitting like
that when I got back. 

At first I thought that it was because I had tried to install all of the
extensions at once, but when I clean-installed and did them all individually, it
still locked up when I hit a certain one. Thinking that I had located a
conflicting/buggy extension, I clean installed again, and skipped it, but around
the same number of extensions later, the browser locked up again.

When I absent-mindedly opened another browser window while the message was up,
it opened fine, and when I looked at the extensions manager, it had loaded some,
but not all of the extensions. I closed both and repeated this process, and a
few more had loaded. I repeated this a couple more times, and all but one
extension had loaded. Eventually I uninstalled the extension because it would
not change status ("This extension will be installed the next time you restart
FireFox"), and FF appeared to open fine.

However, when I went to install the extension again, it still sat on that
message, meaning that I cannot bypass that limit. Even worse, when I removed a
couple of extensions to "make room" for it, it then went back to the "Finalising
Extension Install" lockup, and I had to open another browser window and
uninstall it.

Reproducible: Always
Steps to Reproduce:
1. Go to the official extensions site listed in the release notes
2. Install about 21 or so extensions from the list
3. Restart browser

Actual Results:  
"Finalising Extension Install" lock up, no further action, even after long
period of time.

Expected Results:  
Finished installation and opened browser.

Was using the default theme, and standard Windows XP configuration.

identical to bug 245610 which I had filed some days ago. Then it was easy to
lock up with two specific extensions only.
