SAFE MODE

• https://support.mozilla.org/kb/Safe+Mode
• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

In Firefox Safe mode these changes are effective:

• all extensions are disabled (about:addons)
• default theme is used (no persona)
• userChrome.css and userContent.css are ignored (chrome folder)
• default toolbar layout is used (file: localstore-safe.rdf)
• Javascript JIT compilers are disabled (prefs: javascript.options.*jit)
• hardware acceleration is disabled (Options > Advanced > General)
• plugins are not affected
• preferences are not affected

TEST

If no issues : Create a new profile as a test to check if your current profile is causing the problem.

• https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem. Never work with original files.

If you use Adblock Plus then try uBlock Origin as a replacement to see if that works better.

When my roommate uses my computer using the same Firefox browser to login to his Facebook account he can see all the posts in the same Facebook group. We are both members of the same Facebook group.

So apparently it has something to do with my Facebook account when using the Firefox browser. And when I use another browser with my Facebook account like Chrome or Edge, I can see all the posts.

My only solution is to use Facebook on Chrome or Edge when logged into my Facebook account so I can see all the posts in groups. I'll be using the same computer.

So your roommate is not using a separate Profile then, is using yours ?

My roommate is using his own separate Profile on Facebook. He uses Firefox on my computer. We are both members of the same Facebook Group. With AdBlockPlus enabled in the Add Ons of the Firefox browser Facebook will not let me see older posts in the group but with AdBlockPlus enabled with the Firefox browser it will let him see older posts in the same group when he is logged into his profile on Facebook.

I need AdBlockPlus to block the ads that are in YouTube before each video plays. It's more important for me to play YouTube ad free than see older posts. If I need to see older posts on my Facebook account I'll have to look at them on the Chrome or Edge browser where AdBlock Plus does not exist.

Yes, AdBlock Plus is causing the problem, but I don't know how to use UBlock Origin to block the ads that play on YouTube before each video. Will it do that?
