FF does cannot load servers, IE does and I did all suggested to no avail
This morning Firefox stopped connecting to servers without any obvious reason or change, issuing the "Server not found". IE works fine.
I went through all the 'server not found" troubleshooting to no avail:
- no proxy
- DNS prefetching
- IPv6
- had 4 different scans for viruses/malware -- clean
I prefer not to have to reset FF in order not to lose the config settings.
Any ideas? Thanks.

I also uninstalled security software to no avail.
Some problems occurs when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;
- Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
- Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see
Configure firewalls so that Firefox can access the Internet. {web link}
That wasn't it.
Turned out there was a temp hw issue which was invisible.
Don't ask me why IE did work.
