Updated FireFox on Windows 11 and everything went to hell

[KS Toronado]

Before update very seldom would I see ads, now I'm overloaded with them that it slows this old computer down.

Under settings in the FireFox menu I found this "All add-ons have been disabled by safe mode.
Adblock Plus - free ad blocker (disabled)
Block YouTube™ ads, pop-ups & fight malware!"

Disabled about 10 add-ons total.

Did internet search to turn back on, followed instructions and nothing came back on.

How do I opt out of personalized recommendations in the Add-ons Manager?

To turn off personalized recommendations in the Add-ons Manager:

Click the menu button Fx89menuButton and select Settings.
In the Privacy & Security panel, scroll down to Data Collection and Use and un-check the box that reads, Allow Firefox to make personalized extension recommendations.

Makes me wonder if what I clicked on to update FireFox was really from them, it had been popping up on my screen for about 2 weeks to update and finally hit update, now I wish I hadn't. How do I get Adblock Plus and the other ones up and doing their jobs again?
Thanks in advance, Mike

On Edit........
Forgot to mention below where it said " "All add-ons have been disabled by safe mode." and listed everything they turned off was this Recommended Extensions list, almost like they're promoting or selling something that does the same stuff that they just turned off. That's why I keep wondering if the update was really from FireFox.
