What browser do you use and why? 🌐

Firefox:

• It's pretty fast and stable now
• Better ad blocking and privacy than Chrome by a mile
• Uses own rendering engine which is important to keep the web standard based and not implementation based
• Has good, reasonably customizable UI and scales well to the 50~ tabs I have open
• Doesn't flood the system with 50+ processes because I have a lot of tabs

brave for ad blocking

• Firefox for daily use and front-end web development (dev tools are so good)
• Chrome for work things (we use Google Drive, Calendar, other tools)
• Safari for when I want to look at a page and don't want to clear all my cache, cookies, etc. 😹

Vivaldi for personal browsing, chrome and Firefox for work.

Vivaldi is just a joy to use due to the tab stacking, shortcut customisation being easy and other handy features built in.

I mainly split my time between Safari & Firefox:

Safari:

1. Well-supported by Apple
2. Minimalistic and clean interface that matches the OS X UI/UX perfectly
3. Very customizable (to an extent), I love the way extensions are placed in the toolbar (just wish the were more of them)

Firefox:

1. Very very customizable
2. Loads of plugins
3. Private and stable
4. Good dev tools

If you want to go fast, use safari, but if you want to go "Feature Fast", use chrome because is far ahead from the others, it let developers provide better experiences .. and the only reason to use Firefox it's because you don't like google !

Opera GX (windows only, i think). It has some nice features such as:

• Clicking on the tab title gets you to the top and clicking it again takes you back down to where you where at. This is great when you're on a long article.
• Workspaces: it lets you have groups of tabs separated in workspaces. They are like tabs located on the left side. Great when working with many tabs.
• Instant search: CTRL+Space lets you make a quick search on the web or in your opened tabs titles. Very useful to find a tab.
• Integrated VPN

There are some other cool features too

Firefox ! Normal et Dev edition. (Dev edition to separate to Sync account and install unsigned extensions). Because it's FOSS, because as a dev the experience is better (contexts, devtools organisation, "Edit and Resend" XHR feature, lot's of extensions (addons.mozilla.org is opensource too)), non profit foundation behind and because I don't trust Google so Chrome is no exception. The design is great and the possibility to customize colors through color.firefox.com is very cool). For non tech users, it already blocks 2000 known trackers (like Google Analytics) (what should be already done with ublock origina and privacy badger if you have installed them).
Because Firefox Sync is very useful !
And to tests web apps with multiple accounts the different contexts possibility is great.

Edge, for the ability to "install" web apps and alt+tab to them.

chromium: work
chrome: work break (youtube)
firefox: personal

The reason I don't use FF for work is that it seems to have memory leaks if I leave the debug tools open (which I often do).
