The majority of these crashes are all on Win 7 hardware. In the last week I only see one Win Vista crash.
I found a possible way to reproduce this bug:

1) Install Load [url=]Tabs Progressively 1.6[/url] or 1.61pre to a Nightly build.
2) Open this feed with Google Reader: (just an example, I have many feed that crash).

It should crash your browser.

Crash report example:
Bug related:

Now the question is, the extension need to be updated or the bug?

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:7.0a1) Gecko/20110530 Firefox/7.0a1
The right link to extension above is

Bugzilla need to add a way to user edit their posts (bug 540).
(In reply to comment #2)
Your crash report indicates that 81 other extensions were installed too. Could you repeat your test with a profile that has only LTP installed and post the crash report?
Sorry, for the poor report example. I was able to reproduce this problem in a new profile, I forgot to get the right link. I tried a new profile again, similar behavior, but a different crash:

Firefox 7.0a1 Crash Report [@ mozjs.dll@0x4255c ]

Browser restarted several times, but don't crash anymore. I'm confused now! Anyway, if I found a way to reproduce it again I will report here.

Sorry for wasted your time here.
