Fix for firefox crashes on flash contents when using libflashsupport in hardy

Sponsored Link
If you start using Firefox 3 with Flash, odds are good that you'll experience Firefox crashing every few minutes while loading Flash. It seems Pulseaudio (Hardy's new sound system) is triggering a bug in Flashplayer, which causes Firefox to crash. Since Flash is closed-source software, there's no chance Ubuntu is able to fix the problem in time for Hardy Heron's release.


First you need to download and Install nspluginwrapper from here

Now you need to install libflashsupport using the following command

sudo apt-get install libflashsupport

Now Run the following commands

sudo apt-get remove --purge flashplugin-nonfree

sudo apt-get install flashplugin-nonfree

Now you need to Restart firefox

    hey thnx for the nspluginwrapper, its working good so far for me, i’ve been watching alota videos on youtube jus to see it crash cuz thts wat always happen when i go there, but to my surprise i havent had one crash yet.
    this plugin is a life saver, the only drawback is it makes the video loads jus a lil bit slower than usual but thts bearable
    thnx again !

    I had problems with Firefox and IE crashing all the time. I’ve just upgraded my laptops RAM from 512Mb to 2Gb and it’s stopped crashing. My guess is that a lot of internet sites now have videos and gizmos etc running on them and my RAM wasn’t man enough to deal with it.

    I found found what seems to be the source of this problem for Ubuntu Users:


    I disconected my screen saver and since I have not had a single crash in any programe:
    “as well as firefox my other programmes, games or applications would close(crash) from time to time but now its been 36 hours of crash free sailing .
    Hope this works for you guys

    OK I have found that the screen saver option is not the real problem BUt i have reduced the crashing by quite a lot! how ? you ask!

    ok listen UP people: the Idea came to me when someone mentioned that it was happening to machines running in “parallel Ram” mode!


    and (i think this did it) I INCREASED THE AMOUNT OF RAM RESERVED FOR VIDEO FROM 30 TO 100

    The result?:
    1.A lot less crashes(firefox is still bugging a little but rare other progs. clean)
    2.I can watch movies full screen with no choppy images or sound displacement

    I hope this works for you guys, all the best to you all


  5. I am on Hardy, and these directions worked perfect!

    Thank you, UbuntuGeek!

    I’m on Hardy as well, but I ran into trouble. Looks like the step “sudo apt-get install flashplugin-nonfree” fails with a 404 error.

    The current link on Adobe site is where you can get install_flash_player_10_linux.deb and install via “sudo dpkg -i install_flash_player_10_linux.deb” I was able to use flash without restarting FF.

    Yes, firefox craches and crashes and crashes and crashes across various versions regardless of activity. It did not do this in the past but IE did. And then some snotnose kid name firefox said “look at me, I have the testicular sufficiency that ie lacks, I’m perfect.” And the world fell in love–probably even fondles firefox’s keyboard and all. But just as Microsoft familiarity bred customer contempt firefox is doing the same thing, perhaps more, verging on hate with a vengence. Hang out a suffer if you want.

    Today IRON is where FF was about the time of FF v01. By my reconning we have a couple of years of clean sailing before IRON screws up as well. Its software, the company will declare you to be the revenue center that supports their product regardless of its condition.

    this tip didn’t do jack for me…

    My experience .. FF 3.04, crashing on flash intensive sites including rotten tomatoes, eddiebauer, etc.

    I reinstalled the latest Flash .. no help
    I disabled flash .. no help
    I disabled the AVG Safe Search … NOW NO PROBLEMS!

    I use AVG anti virus and in it’s latest incarnations it installs these browser “aids”. While I have liked AVG in the past it seems they are becoming as intrusive as Norton or McAffee is/was. Not exactly loving AVG’s newest stuff.

    You results may vary but this works for me.
