When I click add-ons it briefly shows then disappears
I am trying to access my Add-ons. When I press the three horizontal bars (top right) and click Add-ons they briefly show then disappear.The Add-ons are working but I am not able to access them. This has only happened since Firefox updated

Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A
Do these work?
As to the 'three horizontal bars,'
Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
The problem is not there in safe mode. The add-ons appear as they should
Please Refresh but do this 1st:

- https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles
then
TEST....... If no issues then Extensions which need to be added back in 1 at a time and tested ..... Or it is your Profile : Make a new one and test ...:
If is your Profile :

Note: Any customization will revert back to default, you will also need to reinstall Extensions.
Please let us know if this solved your issue or if need further assistance.
It could be the work of one of your add-ons, or it could be Hardware Acceleration.

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.
Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.
If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.
Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.
It is possible there is a problem with files in the profile folder that store the extensions registry.
Delete the extensions.* files (extensions.json, extensions.ini, extensions.sqlite) and delete compatibility.ini in the Firefox profile folder with Firefox closed to reset the extensions registry.
New files will be created when required.

You can check if there is a update available in case of issues.
- click the cogwheel button (left of the Search bar) on the about:addons page to "Check for Updates"
If this didn't help then delete add-ons.json and possibly prefs.js in case there is a problem with preferences.
You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

I think the problem is in the latest FireFox update. When you try to access Add-on manager it says not compatible with FF Quantum
Let’s do a full clean re-install;
Download Firefox For All languages And Systems {web link}
Save the file. Then Close Firefox.
Using your file browser, open the Programs Folder on your computer.
Windows: C:\Program Files C:\Program Files (x86)
Mac: Open the "Applications" folder. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac
Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux; https://support.mozilla.org/en-US/kb/install-firefox-linux
If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ Do Not remove the profiles folder.
Look for, and rename any Mozilla or Firefox program folders by adding .old to them. Do not rename the Mozilla Thunderbird folder if there is one.
After rebooting the computer, run a registry scanner if you have one. Then run the installer. If all goes well, remove the OLD folders when you are done. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.
