Hi.

Ever since I upgraded to version 123.0.1, I am constantly getting slowness on websites stuck in "Performing a TLS handshake..." Eventually the websites load, but it's frustrating. I have read about the various solutions and have tried the following: Disabled IPV6 Refreshed Firefox Reloaded Firefox Disabled and removed all extensions Restart in safe mode Create new profile

This was not happening in version 122 and before. Microsoft Edge does not have this problem, but I prefer to use Firefox. I am running Windows 11 Pro. Any ideas?

Thanks

I have set my DNS over HTTPS setting to OFF from the default and it has fixed the issue. I am using ExpressVPN's DNS servers for my queries. Like I mentioned earlier, this was not an issue for me in earlier versions of Firefox. Only since I upgraded to 123.0.1.

Thanks

Hi,

It appears to be related to ExpressVPN. When I disconnect from the VPN, all is ok. Once connected, the issues happen. Is there setting in Firefox under DNS over HTTPS that I should be at. It currently is set at Default Protection.

Thanks

Hi,

Is there setting in Firefox under DNS over HTTPS, or anywhere else that I should have set to allow me to browse while connected to my VPN and not be stuck on "Performing a TLS handshake"? The solution to disconnect defeats the purpose of having a VPN.

Thanks
