Why does Firefox, AND ONLY FIREFOX 145.02 fail to load ANY AND ALL websites after Windows 11 pro x64 startup? I have to close Firefox, restart it, then close and restart it at least 3 times before websites will load fully. AND IT IS NOT A WINDOWS 11 PRO x64 issue.

Thanks, as always, I appreciate any help,

I have Firefox on two Apple devices- IP address location and speed is fine on one but IP address on the other is nowhere near where I live and the processing speed is very slow.This IP address appears blocked on some sites. I am not operating a VPN. Safari on the same machine works fine, with correct location and good speed. I have tried all the Fixes that I can find on line without success. Firefox is up to date.

Why can't I send outgoing email on my BT Premium email account from within Thunderbird, when the Norton VPN. I get a timed out or policy block message. Somewhat perversely, it works when the VPN connection is on. although you warn that VPN connections may be rejected.

Any info or ideas?

why is it a web site accessed couple days ago, now times out trying to re-access it another day?

i called the web place in question and their system is up.

thank you

The operating system is Windows 11, and the following content is configured in the HOSTS file on the C drive: 192.168.10.10 www.simon.com 192.168.20.10 www.simon.com There are two private network servers providing website services, with server A's IP at 192.168.10.10 and server B's IP at 192.168.20.10. Then use Firefox to browse the website www.simon.com and set up Firefox's network.dnsCacheEntries、network.dnsCacheExpiration、network.dnsCacheExpirationGracePeriod Three configuration items are 0. When accessing normally, www.simon.com points to 192.168.10.10. When the 192.168.10.10 server fails, will it redirect to 192.168.20.10. What is the latency for switching domain names in Firefox? What is the mechanism for switching?
