That particular one is done as of October 2022. However, it looks like you are doing more intensive work on your phone than I am on mine. Perhaps I just lack imagination, but I never could figure out what I could do with tasker to improve my usage, and I understand what it can do. It’s just my life apparently doesn’t demand such solutions.
I personally never experienced the issues described in Firefox. Perhaps I was just lucky. I will say that Chromite is definitely snappier than Firefox. If you haven’t tried it yet, take a look. It is chock full of privacy protecting features, too.
