I used it in a prior iteration, both at work and on my home computer. At this time my current employer doesn't use Mozilla Firefox as our default browser.
One of the things I like about Mozilla Firefox is its ease of use. The interface is very intuitive, and easy to manage my favorites and saved history with.
Pros
User Interface
Ease of Use
Good data management
Cons
I found the browser was unstable sometimes.
Loss of bookmarks if there is an upgrade to my operating system.

For a good experience at home, I recommend Firefox. For work purposes, with regular or irregular updates to our systems, it made Firefox unstable, and difficult to manage. There were several instances where Firefox started up and froze for minutes at a time, again mainly due to upgrades. I suggest a full review of impacted systems before every upgrade, and keeping restore as an option, fully backing up everything before an update.
Mozilla is excellent at what it does, but third-party updates, particularly in Windows, sometimes cause it to malfunction.
Mozilla Firefox is used as our alternative testing browser for validating our ERP and various web applications. The rendering engine helps troubleshoot very tricky issues we couldn't debug otherwise with Chromium engines. Things like animation adjustments, JS stepping, network and cache inspection, and CSS rendering on mobile and various screen resolutions.
Pros
Debugging
Video Playback
Customization
Cons
More Customizable UI Sizes
Vertical Tabs
AI Tools

Mozilla Firefox is hands-down the easiest to use web browser for troubleshooting web development adjacent issues and for certain employees who need assistance. We use it for handling network related issues as well as for users that have accessibility issues with certain websites. Mozilla Firefox has more accessibility tools built in than any other number of tools packaged with Mozilla Firefox.
