Your best bet as far as I'm concerned is to make sure you have Flash Player, the graphics driver and Windows up to date.

If none of the solutions help, try resetting the browser, or better yet: create a new profile first and test it to see if you are experiencing issues with Flash Player using it as well.Īs I said earlier, there are so many different solutions that it is difficult to list them all on a single page.

Note that this workaround may have security implications on the system.

Note that this will not help on Windows as Flash Player is hard coded to run in its own process. You also need to set to false if you do.

Search for and change its value to a higher value. Type about:config and hit enter in the address bar. Update your operating system with the latest patches.You can get the latest drivers for NVIDIA and AMD by following the links in this sentence. Update your video card driver to the latest version.To do so, load about:addons, switch to plugins, and disable those that you do not need. Disable other plugins that you do not need, especially Silverlight.To do so press Alt, and select Help > Restart with Add-ons Disabled. The easiest way to run a quick test is to run Firefox in Safe Mode as this will disable hardware acceleration for that session. If you have the latest version, try uninstalling it and install it anew afterwards.Note that Shockwave Player is different from Adobe Flash Player. Make sure the latest version of the plugin is installed on the system.supports playing locally downloaded/stored *.swf files (as long as they're not published for the AIR desktop runtime) + thanks for /u/PornoOnMyAppleIIe for pointing out the hidden option to enable this. If it works for you then consider enabling this option yourself in 'about:config' browser DPI scaling is disabled due to poor flash support for high DPI displays. no flash updates/no browser update (update system deliberately crippled so practically will work forever) You can use my already packaged portable version of Firefox from this link: In addition to the tutorial I also had to break the Firefox update services, because at some point it would update itself silently and break the flash plugin. Following this tutorial I've managed to put together an older portable Firefox browser (ver.70) packaged with an older Flash player (that doesn't contain the time bomb).
