HI, Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox are most probably caused by a recent Flash update and/or a malfunctioning browser plugin such as Real Player.

In order to remedy the problem, please perform the steps mentioned in these Knowledge Base articles:

• Flash Plugin - Keep it up to date and troubleshoot problems

• Adobe Flash plugin has crashed - Prevent it from happening again

• Flash 11.3 doesn't load video in Firefox

Other, more technical information about these issues can be found under these Links:

Please tell us if this helped!

Hi,

Thank you for your quick response.

I check out. Created extra profile, checked protected mode. The URL www.classicalkusc.org/stream/listen.html still failed to load (it is audio only).

Surprisingly video on http://forums.adobe.com/thread/1018071?tstart=0 works.

I already contacted KUSC, they did not find any bug in their software and in chrome it works fine :-(

Any additional hints?

Open the website, right click on the middle of the page and choose Page Info

In Page Info > Permission

• Choose " Allow"

Hi, I select "allow" especially for flash on page information but it still does not play any music.

btw I visit this site with previous FF+flash combinations 402 times (according to page information) without any problems - issue is either since last FF (25.0.1) or flash update (11.9.900.152).

Could you try with Flash Beta version

Are you using adblock or flash block?

whether youtube is working fine?

Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

• On Windows you can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
• On Mac you can open Firefox 4.0+ in Safe Mode by holding the option key while starting Firefox.
• On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
• Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Once you get the pop-up, just select "'Start in Safe Mode"

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.

Thank you.
