For months now I have been plagued with issues regarding Flash content in my browsers. Regularly when I try to load (e.g.) a YouTube video, the browser will hang and I have to kill plugin-container.exe to regain control. Also, an issue which always occurs is a 3-5 second delay when I switch to full-screen video mode on YouTube, BBC iPlayer, or any other streaming Flash video.
I have searched for solutions to no avail and have tried disabling hardware acceleration, clearing my cookies, new browser profiles, reinstalling Flash itself, etc.. I am very much open to suggestions now, please.
My system info is: Windows 7 x64, 16GB RAM, 3.2GHz Intel quad core, 2 x Nvidia GTX 580 in SLI. I doubt it's a performance issue. I am running Comodo Antivirus/Firewall but disabling this does not help, either.
Any help is massively appreciated. Thanks.
