I stopped using Firefox because all my apps did not work on it. My Salesforce app, for example, didn't work on it. Part of my VOIP, which I depend on, does not work on it. And when I called support, all they say is to use Chrome. I'm not an assembly language programmer so I can't go to the bare metal to figure it out. That's what Firefox is supposed to do. I don't have time to figure any of it out, I have a job to do. Maybe it is my fault that some toggle is switched wrong, and I gave a cursory DuckDuckGo search to try to figure it out, but after an hour of looking, fruck it, I got other shlit to do, man. Plus, Firefox is slow as molasses over the last year, so much so that I have to reboot several times a day. Starts out ok, but gets up to 100% disk and 100% memory usage. Using Chrome, it works fine without maxing out disk and memory. I've used Firefox forever, and would prefer to keep using it, but it's just reached the tipping point for me this year. It kills me to go to chrome (Brave, actually) and I kept using Firefox a long time after it started giving me issues. But at some point, just gotta let go. I know that the incompatibility is caused by Google on purpose, it pisses me off, but I still have to get work done. What can one do?
