I use Firefox with standard security options and the uBlock Origin Add-On on my Android phone and I virtually never see what you describe, bar the tracking consent nag screen ofc. Maybe we visit vastly different web content?

I guess if my experience was as much degraded as yours I wouldn't bother with the web anymore, so yay for AI summarizers, at least for the time being. And don't get me wrong, a summarizer is a workaround, not a solution.

There is an extension called "I still don't care about cookies" that mostly solves the nag screens (There's also a similar one that doesn't have the "still" in its name but that one was bought by an ad company and enshittified.) AFAIU it usually accepts the cookies though, so you should combine it with something that clears your cookies periodically.

Sometimes it breaks the site so that you can't scroll or something, but that's quite rare. And most of the time it's solved by a refresh. Very infrequently you need to whitelist the site and then deal with the nag screen manually. A bit annoying, but way better than rawdogging it.

Works on desktop & mobile.
