Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Unfortunately, safe mode, no difference. BUT if using my vpn, even to my own country, it works fine. This is not the wanted solution. Even https://www.google.com/ doesn't work:

I wanted to add an screen copy of the error message. If I would post it in dutch it wouldn't be so understandable for everyone. So I changed he Firefox interface language. Didn't work. Then I used a VPN to the UK. Didn't work either. Then I changed the Search language into English and.....no error appeared anymore????!!!! Switching back to dutch doesn't give problems anymore.

But Switching vpn off and all the problems back again. Even https://www.google.com/ doesn't work any more. Attaching a jpg doesn't work either.

VPN is now switched on and I upload the error screen dump again. Will it work now? No. Without screen dump?

I called for more help.

Hi Fred,

How long takes it posting a response here before it becomes visible?

I have done a lot of things. Safe mode Checked Hosts. Google could be blocked. Run a total virus scan, Checked with malwarebytes.

Nothing helps and nothing is found. So I will reinstall windows from scratch. The more because a friends laptop doesn't have this problems on our network.

Thanks for your help

Rob

As told in the other question, I'll reinstall windows.
