Tahoe has been giving spinning wheel on Firefox browser since updating it. You switch from spotlight to Firefox, there's the wheel; leave computer alone for sometime and comeback there's the wheel. I want this mess fixed.

Similarly on iOS, Safari bookmarks don't expose all folder names but only "Bookmarks" and "Favourites" as default. Why do I have to do another extra tap to expose a single folder that I have to save bookmark in? Why cannot at least five folder names be exposed? Another absurdity is while saving a fullpage screenshot after cropping it, you have to click the checkmark "emoji" which is otherwise blank with no description, and then comes a sub-menu to save as pdf or photo; why cannot those four options be presented as is on the main menu?

You are definitely not alone:

While there are a few overlapping/similar issues being alluded to in those threads, it definitely seems like something is going on re: task switching. There are also a couple of tricks mentioned that might fix some specific issues related to bookmarks or graphics acceleration, but no silver bullets so far.

I have similar issues with Firefox on Linux, I don't think it's a macOS exclusive problem. Unfortunately it's hard to tell which problems are caused by which component when all of them are unreliable enough that they could be the culprit.

The Firefox issue sounds like a Mozilla issue, not an Apple one. It’s not like Apple doesn’t ship betas for developers to catch issues like that.
