OK I just deleted MS Security update KB 2310138 and tried to revert to Firefox 98.02 Not sure who is causing the problem I now see that Firefox wants to update Still deciding who the issue is with so I will install MS and post my results

OK I just installed MS Security update KB 2310138 and Firefox loads as desired In my settings it proclaims Firefox 99 was installed but below it asks me to install Firefox 99 That is NOT going to happen until I see a response

Well the issue of Firefox 99 update is not that the update is not functioning By that I mean it was loading only to the Task Bar It is loading so SLOW that the monitor screen is taking more than 30 sec to paint the screen I have 64 gig of RAM and a 4 Gig new Graphics card So I deleted the 99 update and tested load time to paint the screen It paints the screen in 6 to 10 sec with Firefox 89.0.2 I am sorry to say I find others posting other sites with the same complaint and these are people with super high end graphics cards and way more ram not sure about the ISP provider Sorry I am not going to be polite about this Clown Camp updates Do you even test this on other machines ? Sorry if I am wining about 10 sec vs 30 sec You need to focus on load times
