I frequently get the "Firefox can't find the server" error message.
I frequently get the "Firefox can't find the server" error message. Refreshing the page normally causes the page to load, although sometimes it takes more than one try.
I have checked my connection settings. IPv6 and DNS prefetching are disabled, as recommended by this article: https://support.mozilla.com/en-US/kb/Firefox%20cannot%20load%20websites%20but%20other%20programs%20can?s=Firefox+can%27t+find+the+server+at&r=1&as=s

You can try to reset (power off/on) the router.

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.

I did that before I posted, but it didn't resolve the problem.
I'm wondering if this might be an issue with my ISP, router, or modem. Later, I tried browsing in Internet Explorer (painful!) and occasionally got the same error.

This problem has cleared up on its own, so I assume that it was on my ISP's end.
