I still like my NoScript, sometimes I just take it as an indicator of who makes shitty sites.
If I end up on a site that's completely blank and it isn't important for me to interact with it, Ieave.
Surprisingly even news sites often load better than most others with NoScript disabling everything on them, I guess at the end of the day they still really need people to read them otherwise they'd become completely irrelevant?

I've seen complaints (Reddit I think?)that it just makes it cumbersome to do stuff when there are cascading lists of domain opening as you enable one, but if you're the kind of person that permanently whitelists all of them at that point, I don't think any amount of add-ons are going to save you, but I do like puzzles so I don't mind figuring out what needs to be toggled for site to work.

The big downside is making payments on sites with silly amounts of 3rd parties involved (Im looking at you Costco), but it's a bit better than it used to be when there was concern about getting charged twice, now it's more like...don't get charged and wonder why they didn't process your payment.

Edit: is it NoScript or ublockorigin that blocks ads on prime video? It's one or the other which is nice if you're watching something on pc rather than TV, I guess I should test.

I'm a huge fan of AdNauseam, and TrackMeNot.

Tab Center Reborn (and some css to hide the top tab bar) for sidebar tabs.

I still don't care about cookies

Bitwarden

If you wanna go full degen then "Bypass Paywalls Clean" bypasses Paywalls on the websites with articles. Also "Old Reddit Redirect" is a must if you occasionally open page because it removes this stupid mobile app popup and goes around NSFW login requirement

ClearURLs is nice, it makes links a lot shorter and removes all the tracking junk from it. I also can't live without SponsorBlock and Return YouTube Dislike

uBlacklist is great for hiding horrid search results.

Dark reader. Dont wanna burn my eyes

I don't want to say its name, cause I worry (maybe unnecessarily) about making it a target, but there's a downloader for YouTube that's the only extension I've ever paid for.

Behind the Overlay.

I still don't care about cookies, Simple translate and Hoverzoom+. Sidebery is great too if you want a custom Firefox. Honorable mentioned, YouTube repeat button.

While we're on the subject, does anyone know of a way to block those scroll triggered pop-ups that are everywhere these days? You know the ones, you get a little bit down a page, then:

Any help is greatly appreciated.

next to ublock i also use Decentraleyes
(further protection aganst tracking,
probably a bit less mobile usage,
and otherwise 0 impact)

video background play fix
(prevents youtube from stopping if my smartphone is locked)

ublacklist
(prevents sites you hate from appearing in your google search results (mostly fandom.com for me))

Consent-o-matic. Auto decline gpdr popups.
