From the bugs marked as duplicate:

Steps to reproduce this bug

1. Go to http://www.bwin.com (for example)
2. Wait a few seconds or try to click on any flash button

Also, i don't believe it's very friendly to mark the original bug reports as duplicates of your report, which is actually more recent. Shouldn't it be the other way around ?

[evivbulgroz (fremichel)]

sorry but I didnt mark the original bug reports as duplicate ,or it was unintentional ; I just reported this bug via apport and that's all i did . I'm sorry if I made any error.

[Alfredo Matos (alfmatos)]

Ok, my bad then. Maybe it's a feature.

I can confirm that bug

[emorrp1 (emorrp1)]

I can confirm this bug when using the gnash plugin, only occasionally leading to a full crash, more often than not just either collapsing or blanking the flash content area. Removing the plugin, then installing the non-free adobe plugin (labelled as version 9.0 r115) solves the problem.

[Guillaume (bou-gui)]

Not for me ; i do no use Gnash plugin but Adobe plugin.

[Pedro Villavicencio (pedro)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your crash report didn't yield the required information. Please go ahead and submit a new crash report if it crashed again with the latest available package. Thanks in advance for your cooperation and understanding.

[Alfredo Matos (alfmatos)]

I do not agree with closing this bug as invalid.

The apport stack trace might not have yield the necessary results. But this is still a very important and annoying bug. I am prepared to provide more info than just the apport information.

Please note that this has 7 duplicates, and possibly more, see bug 192070 and bug 196248. This is definitely not a random won't debug won't fix bug.

What more is needed to debug this ?

[Guillaume (bou-gui)]

With the site http://www.bwin.com, i always have a crash of Firefox.

Firefox 3.0b5
FlashPlugin non-free 9.0.124.0ubuntu1

What kind of informations can i give for more help ?

Another test with the bwin.com site, launching Firefox in a console ; here is the error message :

[akshaydandekar (akshay-dandekar)]

just wanna ditto the bug.

[emorrp1 (emorrp1)]

Just some more info about its reproducability:
https://www.bwin.com/ crashes without fail approximately 3 seconds after the page seems to have finished loading, this happens in forground and background tabs, with and without mouse action
http://youtube.com/ crashes infrequently, always upon loading a video (i.e. if the video has started, you're safe), reloading the same video will not reproduce the bug

various other sites crash very rarely: http://www.miniclip.com/ http://www.megavideo.com/

flashplugin-nonfree 9.0.124.0ubuntu1
firefox 3.0 3.0~b5+nobinonly-0ubuntu1

hope this helps

[Petr Vasilyev (p-vasilyev)]

I'm having exactly the same problem with symptomes, described by Philip.
http://www.bwin.com as well hangs my firefox with 100% chance.

firefox 3.0~b5+nobinonly-0ubuntu1
flashplugin-nonfree 9.0.124.0ubunutu1

[Alfredo Matos (alfmatos)]

I think we need to reopen this, since it is so easily reproducible.
I don't see any debug symbols for firefox-3.0, what are the steps to get proper debug information for firefox+flashplugin ?

[LordSavage (lordsavage)]

Same here but only on youtube i think.

[Alfredo Matos (alfmatos)]

This is currently being followed up elsewhere also, I believe. See bug 212877.

[John Vivirito (gnomefreak)]

Does moving usr/lib/libflashsupport.so file away fix anyones issues.
For nest bug reports Please only one crash file per bug report and please dont comment on a bug saying its the same without having a crash report to back up the statment as i see 3 bugs in this one bug report. if the workaround i gave doesnt fix this for them please file a new bug report and attach crash report or backtrace.

[Petr Vasilyev (p-vasilyev)]

John,

moving usr/lib/libflashsupport.so did solved my problem, now I firefox doesn't hangs on bwin.com. I'll add a comment later if I'll notice failures.

P.

[Alfredo Matos (alfmatos)]

Moving libflashsupport.so out of the way fixes my issues. Thanks a lot.

The problem is that it is not easy to debug firefox, and apport is failing (invalid retrace). So it would it would be nice to have some understanding of how to provide useful backtraces, even if just to tell apart bugs. If not, then most of these bugs just look all the same. Open Flash => crash firefox...

If it's any help: I've duplicated the bug on Ubuntu 7 and 8. It seemes to be more frequent on Ubuntu 8. I've replicated it in both Firefox 2 and 3

[Steve Scaffidi (sscaffidi)]

I haven't had it happen with Firefox 2, but FF3 it happens quite frequently.
That's only on Hardy though. I haven't tried FF3 on Gutsy.

[Michel D. (ninharsag)]

Since I have moved /usr/lib/libflashsupport.so (i renamed it) i don't have crash anymore with Firefox 3b5 in Hardy (i never had this problem with FF2+gutsy)
Today i just watch about 80 video on Youtube with 0 crash.

Thanks a lot!

[Artur Rona (ari-tczew)]

Sometimes I have got this same bug, when I go on http://wrzuta.pl and click play.

[Adrian Petrescu (apetresc)]

I can also confirm this bug on Ubuntu Hardy on a Macbook Pro.

[xplong (xplong666)]

I confirm the problem... Renaming, deleting or moving /usr/lib/libflashsupport.so solves the problem for me

[Mingxi (yaomingxi)]

I can confirm the bug on hardy beta. moving /usr/lib/libflashsupport.so solves the problem but after moving all the flash menus and controls don't work anymore. Attached is the crash report.

[Corey T. Brochu (cbrochu)]

Just a little bit of info on the nature of the flash crash for youtube. If you quickly change pages just while the video is loading, it will usually be fine, and will consistently crash with a page change shortly thereafter.

 This seems to be related to the way Firefox handles data for each plugin with multiple tabs, because opening a youtube page in another tab will not result in any problem whatsoever, just close the old one afterwards and you're set. So, either something is backing up in a buffer somewhere or old data is overwriting the new ...

[thanhluan001 (thanhluan001)]

I confirm that bug

[Jason Golley (jasongolley-comcast)]

I can confirm this bug. (Hardy w/ Firefox 3 beta 5)

Happened to me when switching from home page to profile on MySpace.

Recreated it though as a guest, simply browsing the site, and then, following Corey Brochu's experiences, was able to recreate on You Tube.

[Steve Dougherty (sdough)]

Confirming. This explains the random crashes.

[harrisonpowers (harrisonpowers)]

was it a good thing i reported? it seems like it was a common issue.

I just reported a crash as Bug #218987
https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/218987

I think it might be the same as this bug. I will try to reproduce using the steps listed here.

[Samnsparky (samnsparky)]

I confirm this bug with Adobe's Flash Player. It randomly happens when viewing YouTube videos.

[harrisonpowers (harrisonpowers)]

i just apt-get upgrade'd to get a new flash and firefox that work with
youtube. check it out!

[rogmorri (frontporsche)]

I was able to easily reproduce bug#194774, and now after renaming /usr/lib/libflashsupport.so, I can no longer reproduce that bug either.

[Matthias Andersson (matthias-andersson)]

I've noticed that about 1:3 or ½ the times I try to play a video (at any location) the browser suddenly segfaults. Even when streaming .asx-files there is a good chance the browser will crash.

[Ketil Vestby (ketil-vestby)]

The reason for inactivity on this bug: On the latest versions of Flash and Firefox in Ubuntu, the problem is non-existand.

[Ketil Vestby (ketil-vestby)]

Fix is released by Macromedia making better Flash plugin, and probably also by the Firefox teams making an hardened Firefox.
