Server not found
I am receiving intermittent "Server not found" messages. And I'll have to try to access the web page by doing a web search for it, then sometimes that doesn't work so I'll have to do something else. I am typing the web address correctly. I don't have trouble with IE9

The way I fixed it was entering the DNS server addresses into the TCP/IP properties - after that the problem vanished and no more "server not found"

The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.
You can try to decrease the value of the pref network.http.max-connections from 255 to a more modest setting like 30 as used in Firefox 3 versions.
This didn't work. Let me clarify a little: In January I started using Firefox as primary Web Browser, at that time it was Firefox 3 I then uddated to Firefox 4, 5, 6, 7, & 8 as they came out. I just started to have the issue with Firefox 8 which I updated to last week. Attached is the Error Screenshot

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
See:
I fixed my Firewall settings and it still doesn't work.
What are the connection settings?
- Tools > Options > Advanced : Network : Connection > Settings
See "Firefox connection settings":
Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
See:
It is set not to use a proxy. IE is set the same way so thats not the issue I'm going to check the second part (profiles) now and I'll let you know.
Hi, It looks like the new profile works, but I want to give it a day or two because the issue was intermittent. If the new profile works how do I know which files are corrupt?
The new profile works. How can I determine which files to transfer and which files to not?
Did you install extensions in the new profile?
It is best to only copy some personal data that you need like bookmarks (places.sqlite or restore the bookmarks from a json backup) and passwords (key3.db and signons.sqlite) and saved form data (formhistory.sqlite).
Thank You.
