After upgrading to FIREFOX 133 everything became a mess !!

Most pages will RANDOMLY not load and show “Security Connection Failed” message, indicating mostly one of this two errors Error code: PR_END_OF_FILE_ERROR Error code: SSL_ERROR_RX_RECORD_TOO_LONG Additionally and consistently trying to access Amazon makes it think I am a Robot, and shows a page with a Captcha but the images do not load (Image attached) 1Password fails in some pages (Such as CNN), the page shows an error message when userid & password are filled in, rendering it useless. NONE of this happen on previous versions of Firefox or on EDGE with the updated Norton360

I have tried: - Uninstalling, deleting all files and re-installing both Firefox and Norton 360 - Deleting the Firefox profile and starting from zero - Using Firefox without any Extension, it works for a while but then fails (memory overlay issue ?) - Loading a few extensions, again works for a while but then fails. If more trhan 4 or 5 extensions are loaded the problem is immediate (memory overlay issue ?) - Turning off Norton sometimes helps get to a page, and when turning it back on keeps working … Sometimes it does not - - Checked all indicaytions on support article https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect without any luck WHAT TO DO ?

Thanks, but had gone through that.

Yesterday going through another support article, tried to follow a recommendation to completely delete rules for Firefox n Norton Firewall, and allow rules to be created again automatically.

Curiously under Program Control there were multiple rules, like if new ones had been created but older spurious one still remained, and even with the Firewall turned of they might have been the cause.

I decided to "Restore to Default" all rules, completely uninstall Norton 360 and re-install it again, and everything has worked fine since.

You can check the connection settings and check for possible issues with a Proxy or VPN service.

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

If you do not need to use a Proxy to connect to internet, select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.
