Starting this morning, I get 'access denied' or 'unrecoverable error' on many sites. These are sites I frequently visit: retail, air travel, etc. Edge doesn't have this problem but I prefer not to use edge if I can help it. My Firefox is uptodate. So is my Windows 10.

"You don't have permission to access..." errors are characteristic of a firewall that protects the server against misuse and this firewall thinks something is suspicious about the HTTP request. If you use a proxy or VPN then try to use a direct connection. Select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

  • Settings -> General -> Network: Connection -> Settings

You can try to clear the Cache and remove the Cookies for websites that cause problems via the padlock button or via "3-bar" Firefox menu button (Options/Preferences) to see if that fixes it.

I've also seen cases where having "Resist Fingerprinting" enabled was causing this issue.

If this all doesn't work then you can try "Forget About This Site" in the right-click context menu of an history item.
