[Bug 230922] [NEW] Firefox grays out and crashes

[shanen (Shannon Jacobs)]

Public bug reported:

Binary package hint: firefox

I'd be pretty shocked if this is a rare crash, but I'm not sure how to
describe it. I'm not sure how to find which previously reported bug it
belongs to. I'm not sure how to diagnose it better. I followed the link
about debugging procedures and the link about Firefox, but I'm not sure
where to begin with that. Right now the only thing I'm sure about is
that Hardy Heron is worse than the previous release. This is not good.

I can describe the fatal behavior pretty well. I normally work with
several Firefox windows open. One of them apparently get overloaded and
and all of them become grayed out and unresponsive. Sometimes they
recover, sometimes not. If not, I can usually force Firefox to close.
When I restart Firefox, it sometimes remembers the previous window
configuration, and sometimes does not. The problem seems most likely to
be triggered by a webpage that involves Java or Flash video.

Visual effects are currently set at Normal, so the graying out behavior
is specific to this setting. Sometimes I am running with no visual
effects and in that case Firefox just freezes. I think the problems are
more frequent with this setting so right now the only diagnostic I can
think of is to try setting the visual effects to the Extra setting to
see if that makes things worse.

I don't know if this is related to the white screen of death which is
affecting this same machine. However, I am sure that those crashes seem
to be worse under Hardy Heron (compared to Gutsy), and that I do have to
do more things to get back to the running state now.

On other machines running Hardy Heron, I don't see exactly the same
problems, but the Hardy Heron machine that I use second most frequently
definitely has serious problems with the JavaScript in Firefox 3. The
really nasty crashes seem to be limited to this particular Sharp machine
(so far and knocking on wood).
