Script Errors Since Updating Firefox
Firefox is basically useless at the moment. I cannot lose another work day due to this issue. I'm on Windows 7 and just updated to Firefox 37.0.2 two days ago. Since the update, scripts have been slowing down page loading to almost nil. I haven't loaded anything new to my browser in the last two weeks. I'm not going to sit around testing a bunch of crap so please don't even suggest it. Either someone has a fix for this issue or please tell how to go back to the previous version of Firefox. If I don't have this problem resolved by the end of the day, I'm done with Firefox.

Hello,
The Refresh feature (called "Reset" in older Firefox versions) can fix many issues by restoring Firefox to its factory default state while saving your bookmarks, history, passwords, cookies, and other essential information.
Note: When you use this feature, you will lose any extensions, toolbar customizations, and some preferences. See the Refresh Firefox - reset add-ons and settings article for more information.
To Refresh Firefox:
- Open the Troubleshooting Information page using one of these methods:
- Click the menu button
, click help 
and select Troubleshooting Information. A new tab containing your troubleshooting information should open.
- If you're unable to access the Help menu, type about:support in your address bar to bring up the Troubleshooting Information page.
- Click the menu button
- At the top right corner of the page, you should see a button that says "Refresh Firefox" ("Reset Firefox" in older Firefox versions). Click on it.
- Firefox will close. After the refresh process is completed, Firefox will show a window with the information that is imported.
- Click Finish and Firefox will reopen.

Do those script errors show the name of the script?
Are that scripts running on the web page or do they have a chrome:// URL indicating that an extension is involved?
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
- Do NOT click the Reset button on the Safe Mode start window
Hi - I completely uninstalled Firefox then reinstalled. Then I performed the Firefox Refresh as suggested. The problem seems to have gone away. I opened a bunch of tabs to test and so far, so good.
Thanks for the help!
