I get the "Server Not Found" error on a regularly visited website, even after following the troubleshooting tips.

On all other websites I visit, I have no trouble. There is one - which I visit regularly and require to visit for my work, which shows up as a Server Not Found error. It took months to discover it was MY problem and not the website's. I cleared my history and was able to access it...until the next day. I found a couple of troubleshooting tips and tried those and they worked...until the next time. This is pretty frustrating and it is only with this one website. Can't I add it to a whitelist or something? Is there such a thing? Thanks for any help.

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

  • Hold down the Shift key and left-click the Reload button
  • Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
  • Press "Command + Shift + R" (Mac)

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: "3-bar" menu button or Tools > Add-ons > Appearance
  • Do NOT click the "Refresh Firefox" button on the Safe Mode start window

Try to disable IPv6 (check for other possible causes as well).

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History > Show All History" or "View > Sidebar > History").

Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks and history and cookies and passwords and cache and exceptions, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.
