firefox cannot connect to internet
I've been using Firefox 67.0 (64 bit) on Ubuntu 18.04 without problem until yesterday, when firefox stopped loading web pages. I can't even open the page for my ADSL modem, which is connected directly to my PC. Firefox sits there with a blank page waiting to connect, and doesn't seem to time out.
I downloaded Firefox 67.0 (64 bit) from the website and installed it in my home directory, and that version works perfectly, but the version that I installed from the Ubuntu repository does not. It looks like some kind of permission problem, but I don't know where to look. Disabling the firewall using UFW has no effect.

Try to create a new profile to test if your current profile is causing the problem.

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

Can you at least open about pages like about:about that lists all available about pages?
Anything useful in the Browser Console?
Yes, I can open about: pages, but nothing else

That was it. Something in my profile was causing the problem.
Steps to fix the problem: 1. Backed up the old profile and exported bookmarks 2. Created a new default-user profile 3. Deleted the old default profile 4. Copied the extensions back over to the new profile 5. Test the new profile 6. Imported bookmarks from the exported file.
