Mac Big Sur 11.2 broke Firefox!

I was using Big Sur 11.1 and Firefox with no problem. Tonight I "upgraded" to 11.2 and Firefox won't open. I used Chrome to download a new install of Firefox (85.0) and it still won't work. When I try to open Firefox it flashes up on the screen just for an instant, then closes. The Firefox icon in the Dock at the bottom of the Mac screen still shows a lighted dot below it, indicating that it's running, but I cannot open the browser.

I gather this 11.2 Big Sur update is brand new (like in the last couple days, I guess.) Anyone else experiencing this?

Thanks

Oops...nevermind. I did a manual restart of the system and it works now.
