Hello sid176,

Try clearing your Java cache, and History.

If you're not sure how to do that go here. --> I'm a Link.

If you still have problems, and are running a 64 bit processor you may want to install Waterfox instead of Firefox. If you do install Waterfox, you should update your plugins.

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

• Don't make any changes on the Safe mode start window.
• https://support.mozilla.org/kb/Safe+Mode

Try to disable hardware acceleration.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
• https://hacks.mozilla.org/2010/09/hardware-acceleration/

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.

You can also try "Disable the hardware acceleration" in the Flash Player.
