I don't remember what I've used before uBlock Origin, but since its appearance it's basically solved the ad blocking on Firefox and became the de-facto standard for the browser.
You probably lost all your users to it, rather that they all stopped using FF.
Most likely AdBlock Plus. It was basically the standard until they started allowing advertisers to pay to not have their ads blocked.

That usually means that whoever utters it was just looking for a sycophantic excuse to go with the bigger threat because it is more convenient to them (for now).
The problem is that anyone trying to actually be better is usually inconsistent and hypocritical at some level as in that "you criticize society, yet you participate in it" comic.
If you attempt to filter out all traces of hypocrisy from your trusted sources, you wind up listening to the absolute worst people.
The people trying to do better are usually the ones struggling with conflicts and inconsistencies.
on Android phone tried many, most recently was using Kiwi Browser, then for some time Firefox until they fucked up UI, so moved to Cromite, though my phone broke (never buy Google Pixel again, first broken phone after 15 years with smartphones and various brands including very low budget), so now I am on my old phone which for some reason doesn't support Cromite, so I am back at Firefox temporarily
Even today it is difficult for me to use Firefox, Mullvad, etc. When I used to use them, almost every time my machine became slow the solution was to kill Firefox.
EDIT: It's true folks, I would love to be able to use Firefox as my primary browser. But all my experience with it (and I used it for more than a decade) has been dogged by its sluggishness.
Speaking personally I have used Firefox pretty much exclusively for 20+ years, always on low-end hardware. It's been years since I last had any performance issues.
I don't even think its about number of tabs. Just yesterday and today, Mullvad browser takes minutes to load a set of about 7 pinned tabs (with no other tabs) on startup, whereas Helium (which is based on Chromium) loads in a second or two close to a hundred tabs.
However, occasionally I'd run into sites with terrible performance issues. Facebook [0] was often insanely slow on Firefox and would sometimes freeze up entirely.
I wanted a Chromium-based browser but didn't want Chrome, Edge, or Brave. I ended up landing on Vivaldi and have been happy with it so far.
[0] Yeah, yeah, ridicule me all you want for still using Facebook, but I enjoy it because I don't have shitty friends.
I know, I know. The community keeps pretending this isn’t an issue for the last, hum, 15 years? But it is, and for people that are looking for a tool and not for a statement, it quickly drives them away from Firefox back to Chrome browsers.
If I manually close it no issue.
I also do not, and have never, experienced this. I've been using Pixel phones since the 3a in 2019/2020.
I'm still going to use Firefox, I just hope the battery issue I experience goes away.
yeah I love Firefox - but it takes a lot of memory + drains battery faster
