Yes

I use it for some tasks at work that don’t function correctly on Firefox (for whatever reason our local intranet doesn’t play nice with FF) but other than that, I am almost exclusively using Firefox.

Now if someone can come up with a better search engine than Google…

Does Vivaldi count? In that case, daily. I did install Firefox recently to try it out again, though.

I use it for a couple things, although my primary browser is Firefox. I use Google Workspace for my business so I have a Chrome profile set up for that. Another business I’m involved with uses M365. It’s easy to set up another Chrome profile for that. I like to keep work separate from my personal stuff and this setup works well for me.

I use Chrome, but Firefox on my android phone. I have had ublock origin installed since the beginning. I only really use it because I manage my YouTube and Google accounts through it, and its handy for sending tabs between my macbook and PC, as well as the various other workflow features I’ve come to rely on over the last decade or so.

Though I recently heard this was a feature on Firefox now. I used to use Firefox prior to chrome, about 15 or so years ago. I’ve been intending to switch back recently but haven’t got round to it yet.

I have Chrome configured as my default browser, armed to the teeth against any possible misbehaviour such as no Javascript. Anything that tries to open a website automatically goes there, and if it wants to work properly has to get onto my whitelist or gets its URL copypasted into Firefox.

I use Firefox as my main browser. It doesn’t seem to like not being my default browser and complains regularly about it, but there’s no way to explain my setup to it so I have to keep saying “no” to the prompt (to be fair it’s only at update time when this happens, and even then it’s occasional so no big deal). JS is on by default but I still have uBO, Enhancer for YT, I don’t care about cookies, and a few other extensions.
