i have that problem on my pc but i was watching youtube then fallout new vegas nexus then i closed it and then start playing a game then when i opened firefox again it was flickering between connecting and new tap

Guys, i have been encountering the same problem as well. I tried a few tips online like turning the hardware acceleration off and clearing up my cache but none of the solutions have worked for me. I would be thankful if someone could help me with this as FF is good for nothing as no site would open. THANKS!

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do not click the Reset button on the Safe mode start window or otherwise make changes.

You can use one of these to start Firefox in Safe mode:

• On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
• On Mac, hold down the Options key while starting Firefox
• Help > Restart with Add-ons Disabled

If it does work in Firefox Safe-mode then disable all extensions (Tools > Add-ons > Extensions) and then try to find which is causing it by enabling one extension at a time until the problem reappears.

Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
