OS: Windows 10 Pro 64-bit with all the latest Windows updates installed; running Windows version 23H2. Firefox release I'm having problems with: 137.0.2. Just upgraded to release/version 137.0.2. The first time I open Firefox each day it takes about 2 to 3 minutes for ANY website to load. Sometimes when a web page does eventually load none of the images display. I have tried same websites using Google Chrome AND Microsoft Edge. Websites don't have problems loading using either of those 2 browsers unless I have Firefox open in another window. If they load slowly, as soon as I close Firefox, web page load quickly in Chrome or Msoft Edge. Not a RAM problem because I typically have around 20% of my RAM being used. Did not have any of these problems using Firefox version 137.0.1. UPDATE: Thought maybe it was one of my add-on/extensions so I checked for updates. Four needed updating. Made the updates and website still no loading properly.
