GMail, Google search and Youtube stop working after 5-10 minutes

Over the past day or two I've been having an issue with various Google products where they work normally after a fresh restart of Firefox but then fail after a period of time. In Gmail, I get an error at the top of the main page saying 'Oops... the system encountered a problem (#001) - Retrying....' at first and then saying 'Not connected.' later. In Youtube, it starts off as thumbnails not loading but clicking through to the video still works. Eventually it stops working and clicking through to a video says 'Not connected to the internet'. Google search will load at first but not go anything when clicking search. Later it won't load at all.

Closing Firefox and reloading it will let everything start working again for a little while, but it stops working properly again within 5-10 minutes.

Loading Gmail in a private window seems to work and stay working. I haven't tried this with Youtube or any of the other google products.

I haven't noticed any issues with any of the other websites that I would use normally.

So far, I've tried disabling hardware acceleration, I've cleared cache, cookies and history. At the moment, I've manually removed my profile, uninstalled Firefox, reinstalled it without any addons or using Sync and the problem is still occurring.

This is with Firefox 99.0.1 (64-bit) under Windows 10. I've been using Edge so far today and haven't run into the issue with Edge. This is on my work laptop that's connected to a domain and is using Sophos Intercept X endpoint protection.

I hadn't tried that yet. Mousing over the Enhanced Tracking Protection icon within gmail showed 'no trackers known to Firefox were detected on this page'. I've turned it off for gmail anyway, but this doesn't appear to have changed the behaviour. It's still failing to load reliably or stay connected.

Did you also clear the cache/history and try again? And also disable all Addons to see if something is blocking sites.

Already cleared cache/history a couple of times. No addons are even installed at this point. I've uninstalled, deleted the profile and reinstalled with no luck. Same issue.

Still works in private browsing mode though, which is odd.

Edit: Just trying the cache/history/cookies clear process again. So this is now a fresh install with a newly cleared profile that has been used to log into gmail, had the enhanced tracking protection turned off, history/cache/cookies cleared, firefox restarted and trying again. Currently it's loaded and I'll keep an eye on it to see if it fails.

Means something is installed that is blocking in non-private mode which only runs limited resources.

Right, understood.

Looking at about:addons, there's nothing listed as being installed. The only things listed under Plugins are OpenH264 and Widevine

So my process for hard-resetting the install earlier was to uninstall then delete the Mozilla folder out of %APPDATA%/Local /LocalLow and /Roaming. Is there anywhere else that I should be looking?

Is there a specific clean slate reinstall process that I should be using to verify whether it's happening on a basic install or whether it has been caused by something else?

Well, it's still definitely having the same problem.

This is still with my previous profile deleted and a fresh install. No add-ons installed, no plugins beyond the default, all data cleared and firefox restarted after turning off the enhanced tracking protection. Hardware acceleration turned off.

If anyone has any ideas for further diagnostic steps that I could take, I'd really appreciate it.

My PC went through a restart and update process over the weekend. Figured I'd try again.

Still a clean install of Firefox with no addons, enhanced tracking protection off, hardware acceleration off and with nothing else running on the PC, gmail loaded fine, worked for 5 minutes or so and then failed with the same 'oops... the system encountered a problem' error.

I've now switched over to using Chrome in the interim and that has been working fine, as did edge. I don't have a private browsing window open with Firefox at the moment, but I suspect it's the same as before because I've never seen it fail in a private browsing window.

Does anyone have any suggestions for any important differences between a clean install of firefox with a new profile and all cache/history/cookies cleared vs opening the same tab in a private browsing window?

Update to Firefox 100.0 today. Still seeing the same issue.
