sometimes firefox will start, then do nothing, no options, can't locate YouTube, will often work normally after a restart, what's wrong
firefox 69.0.1 on a HP8000e SFF3 Ghz, Ice dragon works normally when I switch from a 'dead' fiirefox, but does not allow adblock plus. When I return to firefox, it usually works normally. Not sure if it's me or firefox. Have tried refreshing and lost themes and settings. It didn't seem to work for long. Thank you for any assistance. Will try with extensions disabled next time it occurs.

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.

Thank you.
Resetting did not work, no error messages, seems to be running but won't do anything. If I exit and start Ice Dragon, then return to Firefox, it will work normally. Windows 7, 32 bit, Firefox 69.0.1. When it is working, will not clear the cache and cookies on shutdown, requires manual clear, usually gets to 1 GB used fairly quickly, so I often have to go to options and clear it myself. Otherwise works pretty well.
