Thank you.

What exactly is your local DNS setting? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1796979 Title: Intermittently can't connect to the server Status in Mozilla Firefox: New Status in firefox package in Ubuntu: Confirmed Bug description: Intermittently while browsing old and new sites, I run into a Server Not Found, "Hmm. We’re having trouble finding that site.", "We can’t connect to the server" page. To workaround I will often hold down the enter key to rapidly re-attempt to get to the page or close the tab, try again, and repeat until I get through. The latter is successful much more often than the former. Running in a new Firefox profile and in safe mode seems to make no difference.
