Firefox extremely slow

[mubs]

Maybe an update did it, but for the past few weeks FF has been extremely slow. Takes minutes to load a web page. Chrome does it in under a second. I uninstalled and re-installed but that didn't help; though it did say it is preserving my settings, bookmarks etc. I don't remember seeing an option to obliterate everything and start over.

I use FF for SF, YT and a few other web sites, and Chrome for everything else. Chrome doesn't seem to be good at remembering cookies when defined as an exception, like SF, so I don't have to login again & again. That's because both browsers are set to clear all cookies and cache on browser exit, except of course the exceptions.

Look under Settings --> Privacy & Security --> DNS over HTTPS. Try turning that on or off to see if that makes a difference.

As an aside, Firefox and Brave are the only two mainstream browsers with ongoing support for thorough ad blocking. I've found no combination of settings on Chromium derived browsers like Chrome or Edge that actually work to provide the same level of safety.

Of course I can put an ad blocking appliance in place on site and that's definitely a good option for desktop systems but I still want the blockers to work on systems that move between networks.
