And sadly web became so dominated by Chrome that some pages simply don't work correctly under Firefox. I'm not going to switch bank or my mobile operator just because they suck at properly designing websites.

My son just got his first computer -- a windows pc. He has edge and firefox installed, but no chrome. I told him he cannot trust google :( and should avoid their software as much a possible.

- Search results are not highlighted on the scroll bar, which means no information on grouping at a glance, and can't just scroll to the relevant part. I have to go through matches one by one.

- Font rendering is subtly broken as always. A specific example is font-variant-numeric: tabular-nums, which seems completely broken at least for -apple-system (.SF NS Text); as a result a data aggregation site of mine which I read all the time looks awful, larger numbers may be narrower and vice versa. (Oddly, font-variant-numeric: tabular-nums seems to work for "Fira Sans" on MDN; I haven't found another font it works on.)

- With developer tools open, pages are really slow.

I'm probably forgetting something else.

(I should add that I also forced Safari upon myself, which is a shitshow, problems too numerous to list. Until Google completely removes ad-blocking capabilities I need, Chrome is simply the best there is.)

It's super annoying. This is the state of things at my workplace and it's ridiculous.

OMG I thought I was the only one running into this exact same problem! This has been a deal killer for me.

And FWIW I run into the same DNS-like issues with Firefox on my home network, which uses Cloudflare's 1.1.1.1 DNS. Perhaps it is something to do with the way my company provisions my machine, I don't know. All I know is that Chrome has no issues. I've made efforts to track down the issue but it's ultimately not worth my time.

My personal machine is a Razer Blade.

Also, Chrome works fine.

How about a sane Profile manager? This is something I use heavily on Chrome. The "about:profiles" UI doesn't cut it.

Also when I use Firefox on my non-work Fedora machines (and this is going from Fedora 21 to 29) it seriously chews up memory and CPU. Facebook (yeah, I know) is rendered unusable after about 30 mins. And as other post(s) have pointed out, video playback can be a bit janky. These machines aren't slouches either, i5 ~2.5Ghz 4th or 5th gen, 8GB RAM, SSD, and dedicated graphics cards.

I'd love to switch, but these are things that are deal breakers.

What's your thoughts on Multi-Account Containers? I think it's better to use if your use case for multiple profiles is to keep sessions separate (i.e., keeping work and personal logins to clearly identifiable tabs / windows)

It's not as thorough compared to switching entire profiles but sometimes the above is sufficient. (ex: your history, add-ons and bookmarks are still under the same profile)

I haven't played with MAC (Multi-account Containers) yet but I understand they're a lightweight version of Profiles that can co-exist in a single browser session and have a bunch of neat features (like auto-binding certain sites to certain containers when visited). Would recommend trying out if you've been dissatisfied with the previous approach.

2013 intel chip+integrated graphics runs like a champ and with lower memory usage than chrome (though I am blocking all the ads, which does significantly change performance everywhere).

I don’t want to use Chrome, but I still wouldn’t call that very great.

I've been running Firefox for over a year now on my Kubuntu desktop and haven't had that issue. Not with pre-Quantum or post-Quantum Firefox.

Also, some tabs will continually use more and more memory due to poorly-written JavaScript. That's not really Firefox's fault but Chrome seems to be much more aggressive in shutting those sorts of things down (which can be annoying because if you go over that threshold in your own JavaScript it'll stop working and you'll get ambiguous resource errors in the console).

My tabs might be using a lot of memory though (React + Redux gets reloaded an awful lot).

Regardless, I’d expect my browser to be smart enough to know that allocating even more memory when the system is out and it already uses 12GB is probably not desireable.

Yep, to be honest this is probably me. I use UBo, but I'm willing to make do with less effective rule-based blockers as long as the most obnoxious and intrusive ads are blocked.

You must not have used any recent version of Firefox. It has vastly better and more useful Dev Tools compared to Chrome, especially in regards to the frontend. Firefox Quantum is also significantly more performant.
