Firefox can't load
Firefox can't load is already a subject that I know, is answered here : https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can
But I need help, because I've tried everything inside, and my firefox is still buggy. I am on a point that I consider turning my back on Firefox because It's been months since I try and try again to solve it and I don't see a light of hope.
Problems I have are especially on youtube, and google searchs.
Here what I've tried : - Reinstalling firefox - Refreshing firefox - No color theme in firefox - Deleting all plugins, extensions - Desactivate proxy setting (I don't use a proxy) - network.dns.disableIPv6 is set to true - network.dns.disablePrefetch is set to true - I wiped my history and cache - Internet firewall states firefox is on white list
I have no problem of performance on others browsers - google chrome for example.
Please, could you help me ? Thanks.

For a problem with G and youtube that could be a problem with the TLS 1.3 Early Data feature also known as Zero Round Trip Time Resumption (0rtt). Try changing this preference to false in about:config. You may have to restart afterwards. security.tls.enable_0rtt_data
Did you recently uninstall an application that was using Visual C+ runtime components?
You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.
See "Visual Studio 2015, 2017, 2019, and 2022":
You may also have to install the Visual Studio 2013 Redistributable Package. You need to reboot the computer.
Thank you for your suggestions, but It didn't help very much
Also, based on your link, I checked here : https://learn.microsoft.com/en-us/answers/questions/84775/vcruntime140-1-dll-was-not-found and used this : https://www.techpowerup.com/download/visual-c-redistributable-runtime-package-all-in-one/ to reinstall a bunch of Visual Studio products. Doesn't seem to impact me positively after a reboot, Firefox takes more than 20sec to open on youtube (and shows : please connect to internet) on first try, whereas Chrome takes 3sec and works like a charm.
I tryied to reinstall 2013 / Visual Studio 2013 here https://www.microsoft.com/fr-fr/download/confirmation.aspx?id=40784
Also, I used scannow and DISM.exe. Slight improvement, but not completely okay.
One more info, that could maybe help... after loading youtube 1 time, loading a 2d time goes quicker. Do you see something else I could try ? Thank you
Boot the computer in Windows Safe Mode with network support to see if that has effect.
