The problem is still there. Thank you

FF is mega slow to find the site, then super fast.

What site? Is this with all websites/pages, some, a few?

Make sure you are not blocking content.

Many site issues can be caused by corrupt cookies or cache.

All websites. I will dump the cache, cookies, and history again today

I just dumped ALL of my cache, cookies, and history, and had to re-login again. It helped a ton, but Chromium is much much faster. Thanks

You can check the timings in the Network Monitor.

You can check the Web Console (Tools -> Web Developer) for messages about blocked content and about the presence of mixed or unsafe content.

You can check the Network Monitor to see if content is blocked or otherwise fails to load.

• https://developer.mozilla.org/en-US/docs/Tools/Network_Monitor

If necessary use "Ctrl+F5" or "Ctrl+Shift+R" (Mac: Command+Shift+R) to reload the page and bypass the cache to generate a fresh log.

You can check the connection settings.

• Settings -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.
