if i am watching youtube or something sometimes the browser will stop responding. it only happens when i click another link or press the back button. Does anyone else have this problem and can it be fixed?

i use slackware 12.0

What other plug-ins do you have installed ? For example mplayer-plugin is know to cause crashes when used in combination with flash player plug-in.

application/x-mplayer2 mplayer2 asf,asx,asp Yes

this?

how do i turn it off

did you install mplayer-plugin ? If so, where and how ? (where did you get the package from, was it source or binary ?)

i haven't installed anything on my comptuer except for flash
the plugins i have are from my default installation

I have this problem as well -- some people say to leave another browser window open on a flash page (I have not tried this to see if it works). I have the mplayer plugin as well as flash and really couldn't live without the mplayer plugin (it plays basically anything I throw at it, unlike most of the other video plugins. If you have a suggestion though, feel free.). It only crashes sometimes upon exiting flash pages, not every time, and Firefox's session manager reopens all of the open tabs upon relaunching, so I haven't looked that far into it.

How and where did you install the flash plugin ?

mplayer-plugin is actually designed for use with only mozilla and not firefox. You can try many other solutions such as mozplugger, media player connectivity extension, and xine-mozilla plugin.

I have both flash and mplayer-plugin and I have not noticed this problem (yet). I am on slackware 12. I got the mplayer plugin from linuxpackages.net. I installed flash by downloading the flash9 from adobe.com
http://www.adobe.com/shockwave/downl...h/English.html
then just untar the .tar.gz file and copy libflashplayer.so to /usr/lib/mozilla/plugins/ directory. You don't seem to need the libflashplayer.xpt. It works without it. Try it this way and see if it helps. Uninstall the flashplayer you currently have first.

What worked here:
Put in your Firefox start-up script (/usr/bin/firefox) this line (when FF is not running!)
No more flash crashes since then.

Hello,

I also have this problem. I have Firefox 2.0.0.4 installed with mplayer-plugin 3.45 and Flash 9. I got the mplayer-plugin as a pre-compiled binary from linuxpackages.net (I think). Sometimes it will cause the brower to freeze up - in which case I open a terminal window and kill firefox and that works. Usually it will cause the whole system to freeze in which case I have to manually kill the power to the computer and reboot - not a situation I am thrilled about; ctrl-alt-del would be bad enough, but just killing power is worse! When the system freezes I can't do nothing - not get a new workspace to open a terminal, not terminate the program with any key combos, not exit X with key combos, not reboot the system with key combos, nothing - the system is dead in the water. Definitely not something I expect from Linux - let alone Slackware.

Hello,

Does anyone what that does and why it would work?

I haven't tried the XLIB_SKIP_ARGB_VISUALS fix yet, but a but of googling suggests that it disables composite extension for firefox or something like that. A bit extreme I think, to disable an X thing just for a program. But I guess I will try it.

H_TeXMeX_H, I think you are incorrect here. I have the "mplayerplug-in" plugin working fine with Firefox (which is a product from Mozilla). I went to their website and in their screenshot section they show the plugin working in Firefox. If the official website has it working in Firefox, I think it's pretty safe to bet that it's supposed to work in Firefox. And, to further prove this, I tested the flash plugin in SeaMonkey (the other Mozilla product) and it also froze (it also has the mplayerplug-in plugin, because the plugins reside in the same directory for both Firefox and SeaMonkey). So although there might be a conflict, it's definitely not strictly a Firefox problem.

I will try the XLIB_SKIP_ARGB_VISUALS workaround and get back to you (it's hard to test this bug because it only happens sometimes). There have been reports of this working on Ubuntu with no mention whatsoever of the mplayerplug-in, and I must assume that at least some of them had the Flash plugin without the mplayerplug-in (although I can't be positive). However, I really don't think it's a plugin conflict here -- I think it's strictly a Flash thing.

You might be right ... I don't really know. What hinted to me that it was designed specifically for mozilla was on their site they say " Applications other than mozilla are not supported." And the fact that it can cause these kind of problems let me to further believe that it only supports mozilla, even tho it also seems to work with firefox.

Yeah, I just checked the mozilla plugin site and they list mozillaplug-in as untested in both firefox and seamonkey. It works for me so I guess I'll stick with it anyway.

As for the Flash thing, I tried the "export XLIB_SKIP_ARGB_VISUALS=1" workaround and it seems to work. It's hard to test this bug because crashes only happen ~10% of the time, but I think I tested it thoroughly enough to say that it works. I've also enabled compiz to make sure everything still works fine regarding DRI/composite extension etc. and it seems to work as it should. I got the feeling from the Ubuntu bug report that the workaround disabled something to do with the composite extension but everything seems to be working as normal in compiz (although I don't normally run compiz anyway because of stability issues [mostly regarding GTK apps in KDE], but I figured I should test it out anyway).

I don't know anything about stuff like this, just know it works for me and haven't seen any side effects (but I never use compiz).
Like T3slider mentioned, it's a work-around you can find on several Linux-fora and I never read about negative side effects on these sites, so I guess it's pretty safe.

BTW, never had FF crashes due to flash on SW 10.2 and 11, it popped up on SW 12, on both machines...
But if you Google a bit, the problem turns up on other distro's and other versions of Slack, so I don't think it's related to 12.

BTW 2, on this machine I haven't got the MPlayer plugin installed, and before adding that line to /usr/bin/firefox, I had flash crashes as well (sometimes). Which of course doesn't necessarily mean that this plugin has nothing to do with it, but it's certainly not the only cause (AFAIK).
