Firefox is back. It's time to give it a try

Extensions. Back in the mid-to-late 2000s Tax Mix Plus was released, I had it configured so that after a configurable number of tabs appeared on the tab row, a new row would be created, up to a configurable number of rows after which I think you'd have to start scrolling the tab rows. You could also unload tabs and have them only load when clicked on, thus the memory usage was typically inconsequential even though my laptops back then only had something like 256MB - 1 GB of RAM. I had a tab colorizer installed too. Thus formed my habit of accumulating tabs.

Later on TreeStyle Tab came out, and I've used that ever since. I've got 501 tabs right now (thanks tab count extension), I usually go on purges every so often when it gets around this high and close large groups of them, reading some before closing, bookmarking many of them before closing with a current month/year annotation and other tags, so I can get back down to a more reasonable ~100-200. Even if it didn't have its tree collapsing functionality (I've got 25 tabs collapsed in a tree right now related to setting up and using some new software I started doing last night, it takes up one tab of space when collapsed) I would still use it just for the fundamental insight that with widescreen resolutions being standard vertical screen real estate is much more important than horizontal real estate. Admittedly that's not as big an insight anymore with 4k screens (and I use a big 42inch one). Anyway with TreeStyle Tab I can have tabs that are on the left side of the browser, that grow down, with scrolling, but I can still read the titles of each tab unlike in Chrome where each tab after ~10-20 is just an icon (at best).

The URL bar is also just superior to Chrome's. It's not called the Awesome Bar for no reason. The table at the bottom of https://support.mozilla.org/en-US/kb/awesome-bar-search-fire... has a list of commands you can use to match things -- I actually often have that page in my sea of tabs since sometimes I forget a couple sigils but I found it immediately with ctrl+L + "awesome %".

This submission's title is kind of hilarious. Firefox never went away, I started using it pre 1.5 on a Windows 95 machine and though now I use Chrome/Chromium for some things I've never felt the need to leave Firefox. Well, except until recently with the Quantum updates, ironically. For my personal desktop, I'm still pre-Quantum, it works just as it always has, while on my other machines I've been giving the new Firefox a fair chance and am just hoping it gets better. The tree tabs addon port especially isn't as good, I really miss my right click context menu for noscript, etc.

Google Optimize requires both Chrome and a browser extension (which isn’t available for any other browser) to work.

I've used the snapshot versions as my primary browser at work and home at least since... (referring again to KeePass, checking creation date of credentials for some vivaldi related thing) ...beginning on April 2016, and for me it has worked great.

I might not be the heaviest of the heavy users (figuratively speaking :), for example I have total of 3 Chrome extensions installed (uBlock origin, some exif viewer and Google translate), so I am not aware of things that may not have worked correctly.

I used to use Opera (first 12, then the Chrome version of Opera which I didn't like), and then switched to Vivaldi when I found out about it.

I really like and use Firefox. Just the pdf-viewer is subpar – especially to Safari. If I print Latex-made pdfs from the browser, the font looks odd. Also I can't zoom properly/continuously in via my Mac Trackpad. Can anyone recommend a plugin with a better pdf-viewer for Firefox?
