283246 - Hang when trying to login to Yahoo

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Ray Trent]

For the last week or so, whenever I try to login to my Yahoo account Firefox
hangs, and if I stop it by clicking on the "X" close button it crashes (or at
least the QFA pops up as though it were a crash). This has worked in the past,
but suddenly stopped.

If it's helpful, here are a few TB ids from these pseudo-crashes: TB3871599G,
TB3871548Y. 

It doesn't seem to matter how I get to the point of needing to login, any
attempt to do so hangs FF for me. E.g. replying to a Yahoo Groups or
finance.yahoo.com message, logging in via the URL above, viewing a restricted
Yahoo Group, playing Yahoo Games, etc., etc.

I've tried a few obvious things like flushing my caches and cookies, to no
avail. Now that I think about it, I should probably try a fresh profile... I'll
post results if that is different.

IE works fine, so it's (probably :-) not related to Yahoo's servers or my
account there.

So, perhaps predictably, it WFM with a new profile. That's a somewhat
unsatisfying answer, though, as I have extensive bookmarks, history, settings,
AdBlocks, cookies and other state that I'd really prefer not to lose. 

Is there a good way to copy the user-specific stuff from one profile to another
(while hopefully clearing out enough of the junk to fix this problem)?

BTW, it also works if I start up in "Safe Mode", but not in "Extensions
Disabled" mode.

See Bug 269814 "add repair feature to Firefox profiles"

Ok, this problem goes away if I uninstall AdBlock. I have some sneaking
suspicions that perhaps yahoo is getting cute about adblocking. 

So, not sure whether to close this bug or not. The crash when I close FF in this
state is still a real crash, but perhaps it can be attributed to the extension
rather than FF... Is anyone able to analyze the TB?

As a rule bugs in extensions are not handled in Bugzilla.

If you think that it is a bug if an extension can cause Firefox
to crash (as opposed to removing functionality), you might want
to open a Bug Report on that, preferably with a test case.

I've tracked this down to my AdBlock filter set. Switched in the standard
FilterSet.G and WFM now.

Anyway, I'm closing this. I might open a bug for the resulting crash if you
close FF while the page is stuck, because I've seen a lot of
crash-on-close-while-hung situations lately... but I'll see if I can narrow it
down more first.
