Unable to use several websites; all show the same error - NS_ERROR_FILE_CORRUPTED

Starting last week (with the 88 update?), I've had problems using several sites that I have to login to. It started with Outlook (Office 365), but now includes Zendesk and even the Firefox Account. In the case of Outlook, I got an error message. For Zendesk, I can log in but the page doesn't render. On the FF Account page, I get a message saying cookies and local storage aren't enabled, though they are.

In all cases, there's an 'Uncaught exception...NS_ERROR_FILE_CORRUPTED...' error in the console. I got outlook working by using localStorage.clear() and sessionStorage.clear() in the console, but it was a temporary fix.

I've disabled all extensions to no avail. Some of these sites work in FF safe mode (hence logging in to write this), but Outlook is unresponsive.

What's going on? Is there a fix?

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

You can check for issues with local storage (indexedDB).

This test showed everything working as normal. However, even after reinstalling FF the same issues are occurring.

Refresh Firefox - can't believe I didn't know about it. Seems to have done the trick this time.
