Although it is true that Firefox posts/comments can get tiring, I think you replied yourself. Google is killing adds-blockers, who knows what will happen with chromium-based browsers. Turns out Firefox has nothing to do with chromium, plus they care for privacy, plus it works great and the list goes on.
I find it obvious people will recommend it, even more here, on Lemmy. If you don't like it, downvote it, keep scrolling or just don't click the post.
My own recommendation: mod it, this way you can download and play any PSP game you want, also de PSP is able to run PS1 games natively so yep, you can also play the PS1 library (with a few exceptions).
You can also install homebrews or even retroarch. It's a magnificient console to play retro games on the go.
For me, the psp and the psvita are ones of the best handleds out there. Perfect size and so much to play!
