loading pages
When I want to access a particular page the page appears and then immediately disappears. In another instance I can get to a site but some of the links won't work. When I try and use the link the page appears and then quickly an error 500 Message appears. These problems don't exist If I switch to ms edge. This of course is a pain to have to switch prowsers to reach these pages particular with the site that I can enter but can't use some of the links. Would really appreciate your help

Error 500 may be caused by network issues at your end. But since the websites are opening in MS Edge we can rule that out.
Can you please try the Safe mode/troubleshooting mode of Firefox to see if you are still facing the issue? Go to menu > Help > Troubleshoot Mode
Refer to the KB article Diagnose Firefox issues using Troubleshoot Mode for more details.
If the issue still persists in Troubleshooting mode then please check if the issue still occurs when you use a new profile
- Create a New Profile New Profile.
- Close all the open instances of Firefox browser
- Relaunch Firefox by running the following command firefox.exe -P.
- Select the profile created in the first step
- Once the profile loads please make sure that you do not add any new extension or change any Firefox setting in the new profile before proceeding.
- Now check if the websites load properly.

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.
- switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes

You can check for issues with Enhanced Tracking Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.
- click the shield icon for more detail and possibly disable the protection
You can check the Web Console for relevant-looking messages like blocked content.
