Firefox hangs on starrting on Mac

Firefox 147.0.4 (aarch64) "hangs" for 30 seconds to 1 minute when I launch it on my MacBookPro (OS Tahoe.26.3). Itwon't open the simple web page I have Firefox set to open when it launches -- and I can't navigate to any other web pages. When I try to interrupt, I get an Apple spinning beach ball until finally, Firefox opens that first page.

After working with Apple tech support, I have disabled a number of content barrier Extensions in Firefox-- which Apple tech support felt might have been causing this behavior. Nothing works. And I hesitate to run Firefox without some of them.

I tried deleting my Firefox user profile from my computer, but all that did was prevent Firefox from opening at all.

How can I stop this?
