[Mark Finkle (:mfinkle) (use needinfo?)]

added blocking nom so this gets some attention quickly

I can't reproduce the hang. It's a very quiet site for me.

Comment 3

[Matthias Versen [:Matti]]

wfm in Seamonkey trunk and FF3.5b4
removing blocking because blocking should be only requested on confirmed bug reports.

Comment 4

[Robert Longson [:longsonr]]

WFM too, both 3.5 and trunk on Windows.

Comment 5

[mozilla]

Also hanging in Safe Mode

Comment 6

[Robert Longson [:longsonr]]

You can load just the svg bit via http://svgopen.org/2009/pics/header.svgz does that hang for you? If so can you construct a reduced testcase?

Comment 7

[mozilla]

The .svgz has the same result.
I gotta run now.
I hope to have time to build a reduced testcase tomorrow

Comment 8

[mozilla]

If i use Opera to load the .svgz and save it local and then load it with Fx3.5b4 there is no problem.

Comment 9

[Robert Longson [:longsonr]]

That rather rules out the SVG component. Something going wrong for with your installation in uncompressing the stream perhaps?

Comment 10

[mozilla]

I guessed there would probably also be a .svg instead of .svgz version on-line and guessed right: http://svgopen.org/2009/pics/header.svg
This has the same result, Fx3.5b4 hangs

Comment 11

[mozilla]

i tried a Fx re-install without luck

Comment 12

[Matthias Versen [:Matti]]

reinstalling doesn't fix any errors in 99% of all cases.
http://support.mozilla.com/en-US/kb/Safe+Mode
and a new profile
http://support.mozilla.com/en-US/kb/Managing+Profiles
are the things to do in such a case.

Comment 13

[mozilla]

Comment #5 shows i already tried Safe Mode.
Even went back to a single monitor setup for a bit.

Comment 14

[Matthias Versen [:Matti]]

I have a dual monitor system as well.
You could try to create a windbg stack trace for the hang http://developer.mozilla.org/en/docs/How_to_get_a_stacktrace_with_WinDbg
use an additional "!analyze -v -hang"

Comment 15

[mozilla]

I've downloaded windbg to get the stack trace and will get on it, but shouldn't the Mozilla crash reporter do this? (I guess that depends on where on the crash/hang spectrum it is happening).

I can open the content in a background tab without hanging, but as soon as that tab is no longer in the background ...

Comment 16

[Matthias Versen [:Matti]]

The crash reporter is for crashes and not for hangs

Comment 17

[mozilla]

I just realized that, on which i did a few tries with a lot of patience and at one point managed to close the troubled tab. I'll give that another attempt while looking at resource use.

Comment 18

[mozilla]

Attachment: WinDbg log

Did what you asked. See WinDbg log file. Hope it helps

Comment 19

[mozilla]

My CPU is stuck at about 50% and my mem at about 128M while waiting for the troubled tab to close. Just in case that is of any use.

Comment 20

[Mike Beltzner [:beltzner, not reading bugmail]]

Works fine for me on branch nightly, OSX.

Did you try a new profile?

Comment 22

[mozilla]

No, i didn't

Comment 23

[Tyler Downer [He/Him]]

Please create a new firefox profile.

Comment 24

[mozilla]

Updating to Firefox 3.5 Preview didn't make a difference :-(
I'll look into how to (temporarily) work with a new profile

Comment 25

[mozilla]

With a new profile i don't experience the hang.
But of course i can't miss my history and all.

Comment 26

[Robert Longson [:longsonr]]

I don't think this bug is valid then.
