The wider point here is that you can only use FF as long as Mozilla can fund it and Mozilla can only fund it as long as Google funds them. At some point, it will be cheaper for Google to pay monopoly fines than funding Mozilla.
Technically, both Chrome and Firefox are adware too, since Google's main business is ads, and Firefox/Mozilla get a lot of money from Google to display Google as a search engine in Firefox (an ad :) )
Firefox doesn't sell BATs, in-browser notification ads, or new tab takeovers. The closest you can get is a pinned site in the new tab page (new installs only) and ads in Pocket, or whatever they're calling that new tab thing these days.
Calling Firefox adware is a stretch at best, and disingenuous at worst. Adware doesn't mean that the software survives because of one advertisement that that user can turn off.
Looks like I'm getting a ProtonMail ad every few new tabs. I never noticed because I've never looked at the new tab page. Doesn't noticeably slow it down to have the ad there, luckily.
I love how quickly the goalpost moves from "No ads" to "Only opt in ads" to "Ads can be disabled with two clicks."
Quit coping and just admit it, Brave is adware. If you like it, that's cool, totally your choice. It's fast, performant adware. But it's adware all the same.
When we're talking about reasons to switch browsers, then saying they both have the same behavior is not whataboutism. It's extremely important context to the complaint.
It's good enough when some terrible lazy web designer only tested on Chrome. It does nothing to protect against the future when Google decides they are sick of people trying to get around their Ad Block ban and change the license because no one has any real alternatives anymore.
Also blocking is not as good as intentionally poisoning with something like Ad Nauseum
No Chromium fork developer not called Microsoft have the resources to maintain a web browser engine.
But focus on the license overlooks a more important threat. Google made Web Environment Integrity so services could require approved devices, operating systems, and browsers. Resistance led Google to remove it from desktop for now. But they kept something like it in Android. And they will try again.
I've been using Chrome with uBlock Origin Lite and not even once I found a case when this version of uBlock was behaving differently (as less efficient) than the "full" uBlock Origin
Maybe I'm just lucky, but even this argument is quite ... meh
I've found it a bit like "what car did you drive in to work with today" in that any typical current and working car is not going to be a stark difference to a high end car in terms of how fast you get there... but you'd definitely notice a piece of crap with a donut, broken heating, and screeching brakes causing you problems if that's what you were comparing instead.
I.e. I can count the number of times I said "wow, uBO Lite didn't make this site usable but loading up Firefox with uBO and it worked fine" on one hand. At the same time, if I ever look and compare how much is actually getting blocked, uBO is definitely blocking way more. Doing a side by side compare of dozens of sites it becomes easier to see minor differences I wouldn't otherwise have noted, but may not have mattered as much.
I commented about this a few weeks ago here about this, but essentially: v2 allows you to block things you can't see, but you still probably don't want, like folks hiding cloud analytics behind CNAME cloaking to allow it to appear as a first-party site rather than Google Analytics, for example.
You won't "feel" this in your day-to-day browsing, but if you're concerned about your data being collected, v2 matters.
That's not sucking at blocking thats YouTube intentionally adding a delay to make it seem like their experience is degraded when it isn't. If you turn the slider up to full it only happens very rarely.
I'm sure this will all change eventually though and YouTube has a loophole planned so ad blocking on manifest 2.0 is impossible.
I'm not really sure of the actual mechanism, but on Firefox with a fully updated block list the delay doesn't seem to happen for me. Whereas I could never quite get rid of it on Chrome. This was a while ago, though, when they first introduced it.
I use uBlock Origin with Firefox on Linux, and it seems like that delay happens maybe on 30% of the YouTube videos for me, with no rhyme or reason to which ones. And reloading the same video multiple times show consistent behavior if it loads fast/slow, not sure what's going on.
AFAIK Manifest v2 is still part of the chromium codebase, and there is an intention to continue supporting it, depending on how difficult that turns out to be.
