Hello,

please try Diagnose Firefox issues using Troubleshoot Mode

That is a problem with the Shockwave Flash plugin.

You can check for problems with current Shockwave Flash plugin versions and try this:

• disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
• disable hardware acceleration in the Flash plugin

I have tried all the solution, but with no success

Do the crashes still occur when you disable the Shockwave Flash plugin?
