Brave on iOS for example implemented this 2 years ago:

"Auto Shred lets you automatically delete data for specific sites [...] You can configure Auto Shred to happen when all tabs for a site are closed, or on browser restart. Auto Shredding on Site Tabs Closed means that whenever you close the last tab for a site, Brave will automatically Shred that site’s data."

Firefox including it is likely just reducing the steps required.

Ads shown on search engine results pages, including Google, Bing, DuckDuckGo and other search providers

There are many subpar adblockers available both built into browsers on iOS and as extensions. uBlock Origin Lite for Safari remains the best mobile adblocker on iOS, I suppose.

Firefox does not block:

Sponsored content on the Firefox Home or New Tab page

So block ads unless it impacts their revenue sources.

1. Safari supports extensions

2. WebView, the thing most browsers on iOS are required to use in most places, does not directly support those same extensions. In other words, there is no simple options to allow the same extensions.

In other words, Apple makes it harder for alternative browser to support extensions by requiring them to add their own support. That wouldn't be an issue if Apple allowed alternative browser engines but since they don't (in most places) then it's arguably an added hurdle.

Firefox on iOS has a terrible problem with its autocomplete (I think they replaced the algo with a janky Llm-style autocomplete). When I type “news” into the url bar, it will suggest one of it’s marketing partners (or whatever) but incorrectly such as: newsyorker.com

I dont ever visit The New Yorker but even after clearing caches and site data the problem still persists. I can delete the app and the problem goes away for a short while.

I left a review on the App Store about this and the person (bot?) they hire to respond to reviews asks me to open a ticket. No! How about you port my review over as a ticket and fix your damn software.

I guess I'm not surprised, but it's still annoying.

Now, I can finally watch pirated content without the suspicious ads popping up all the time. (^-^)

on android, f-doid fennec and all other forks do! it's not even hard, so in my view this "is a feature" for mozilla.

then, further remember one person from the board was involved in AdBlock extension who charged firms 1mi to "whitelist good ads". my emoloyer at the time paid under a nda.

still better than nothing (and who am i kidding? 99% here chose to use chrome on their main machine)

(I ask because I want to use one of these for my own app - I don't care which app is nicer to use.)

I've never been able to block their phone-home stuff using about:config

wrt the native adblocker, I like the idea, but I suspect that companies will now be unified in code targeting the adblocker (or the entire browser) to preserve their revenue.

(there was a precedent - when "Do Not Track" was turned on for all users in the browser, companies used that as a reason to ignore it)

It may not yet be available to all users.

Not me, bummer.
