Mozilla Firefox Slow

  Issue in Mozilla Firefox 38

Mozilla has released Firefox 38.0.5 which contains a fix for this problem (Release Notes). To update your version, see Update Firefox to the latest version.

After the recent update to Firefox 38, some Windows users may notice that Firefox responds more slowly while you type in a search, enter a web address, or navigate its controls, than its prior versions.
Mozilla is currently working on a long-term fix, but if you are affected, you can take these steps to fix the issue yourself:

Turn off hardware acceleration

1. Click the menu button and choose Options.
2. Select the Advanced panel and the General tab.
3. Uncheck Use hardware acceleration when available.
4. Click the menu button and then click Exit
5. Start Firefox the way you normally do. 
6.
