About a week ago, Firefox began updating itself every time I started it upon powering up, then it wouldn't connect to the internet. Other browsers, including Chrome, Epic, Yandex, & Edge, connect to the internet. I read the advice about interactions between FF & antivirus. Bitdefender (BD) & Windows 11 are up to date. Until today, I could wait a few minutes, FF would connect, then I'd sync FF, extensions would return, & everything was fine. Today that stopped working. I went to FF settings & selected "no proxy," & that didn't help. I turned off BD, & that didn't help. I reset Windows network, & that didn't help. I turned off the computer then turned it back on, & that didn't help. I ran a complete system scan, through BD, & that turned up nothing. I'm out of solutions. Please help. Thanks.
