Hi,

I'm new to firefox, I'm trying on this new linux based config to change from chrome to firefox, and I've got an error on most of the different website I'm trying to join : "Hmm. We’re having trouble finding that site." For short it's the server not found error, but I can access thoses websites from an other browser.

I'd like to solve this problem, I already tried ipv6 disabling, and dns prefetching enabling from this help page : https://support.mozilla.org/en-US/kb/server-not-found-connection-problem and it still not resolve my problem.

It often resolve alone half an hour after I started firefox, but it is way too long...

Thanks a lot for helping me !

Matthieu

PS : domains I can't access : github, my school website, youtube sometimes...

Soluzione scelta

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?


Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

If the problem goes away with the computer in Safe Mode, the problem is with one of the other programs on the system.

As a test, disable your protection programs.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own. ....

I don't have avast, kaspersky, or anything else trying to watch my connections. I had already found most of thoses links, but none can give a way for me to solve my problem.

It could be the work of one of your add-ons, or it could be Hardware Acceleration. How to disable Hardware Acceleration {web link}

Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.
