Sites using flash/shockwave cause Firefox to hang.

If the shockwave flash plugin is enabled on version >22, visiting a site that contains flash content will cause Firefox to hang/react extremely slowly. I've tried disabling all add-ons with no effect. I'm using shockwave flash 11.2.r202.310 but it doesn't seem to matter when version of flash I use.

Re: Sites using flash/shockwave cause Firefox to hang.

Please ensure that your Firewall/Antivirus program(s) are not interfering with how Firefox connects to the internet.

Ensure that your internet connection is strong and fast.

Does this issue occur on other internet browsers?
Does this issue occur on all pages containing flash content?

Re: Sites using flash/shockwave cause Firefox to hang.

Make sure that Flashblock or one of the other extension aren't the cause of this hang.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window.

Thanks for the replies guys.

ComputerWhiz: No firewall or AV installed on my laptop.

cor-el: Nothing works. It is the shockwave flash plugin + >=v23 that is the problem. I've tried safemode, I've completely deleted everything eg moving the .mozilla directory and started a virgin firefox with the same results.

OH NO!

You don't have any antivirus or firewall programs installed and active on your computer!

Purchase/download a firewall and antivirus program as soon as possible!

Then run a full scan of your computer's hard drives.

Your Adobe Flash Player could have been damaged by a virus or malware.

There is no need of a AV on Linux at all, or much malware (some rootkits, not very many) to infect it.

@Waka_Flocka_Flame

Thank you for that information. I didn't know that. Up until a few months ago, I didn't even know what Linux was.

Sorry about my above answer.
