Firefox stopped working with my VPN on when I updated my OS to Sonoma, yesterday. I use PIA for my VPN. I have done the following, so far, restarting my system several times between trying these things: Checked that internet connection and modem are fine. All pages load in Safari, with VPN running, but I prefer Firefox. Checked the Network settings for my Mac. Ensured that No Proxy was selected. Cleared my Firefox cookies, cache and history. Tried running in troubleshooting mode, turning off all extensions. Tried turning off Advanced Tracking Protection, which I usually run on Custom. Refreshed Firefox. Finally, I turned off my VPN and, viola, all sites work. Turned it back on, and can’t navigate, again. For instance, I tried to open YouTube, and got a blank screen. Turned off VPN, and got to main YouTube page. Turned the VPN on and tried to log in…nope. Turned it off and logged in. Turned it back on and tried to open a video….nope. Turned it off and opened the video…etc., etc.. I very much wish to continue using both Firefox and my VPN. Can you suggest a course of action? Thank you for any advice you can give!!
