Hello

I just upgraded to Firefox 33 and I noticed I have very high CPU load on about:home page. I assume this is because of the integrated Firefox game. When I visit any other website CPU is normal.

Start Firefox in Safe Mode {web link} While you are in safe mode;

Type about:preferences<Enter> in the address bar

Select Advanced > General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites. Are there any problems?

Then restart.

If there are problems with the snippets on the about:home page or you otherwise do not want to see those snippets then you can set the browser.aboutHomeSnippets.updateUrl pref to an empty string on the about:config page.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

Delete the storage\persistent\moz-safe-about+home folder in the Firefox profile folder with Firefox closed ("3-bar" Firefox menu button > Exit/Quit) to remove snippets stored in IndexedDB and make Firefox use a default snippet set. You can reset the browser.aboutHomeSnippets.updateUrl pref via the right-click context menu to the default value to re-enable the snippets and make Firefox recreate the moz-safe-about+home folder. You need to close and restart Firefox after changing the value of the browser.aboutHomeSnippets.updateUrl pref.

You can use this button to go to the currently used Firefox profile folder:
