Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Log into any website with multiple accounts in one window
Pro Projects function removes the need to log in
With the new release (as of Dec 6th 2016), you can save a group of "Sessions" with logins stored to a Project, which you can launch with the click of a button. "Projects" eliminates the need to spend time setting up your workflow every day, so you can get right to work.
Pro Save a set of isolated cookie jars into a project
Pro Color coding for session organization
Different sessions are distinguishable by color for easier organization. You can also rename sessions to fit your needs.
Pro Group your cookie jars
Pro Developer tools for each session
The developer tools work just like Chrome, except that you can separate dev tools by session.
Pro Assign a different proxy to each tab for international sites
Pro Designed specifically for web development
Is the only browser I know with features specifically oriented to aid web development out of the box.
Pro Can be launched alongside Firefox (release version)
Some might find that useless, but that's very practical to dedicate a browser to development.
Pro Standard complaint
AFAIK, Firefox is the most HTML/CSS/JS standard complaint of all the browsers out there.
Pro Feature rich
This browser is the most feature richt browser for web development out of the box.
You can restrict the bandwidth in "Responsive Design Mode" to see how the page performs under unoptimal conditions.
It has predefined profiles for e.g. Ipad, Galaxy S9 and lots more.
Pro Ready for work right out-of-the-box
Pro Fast
It's Firefox. It's fast.
Pro Beta channel
As this branch of firefox uses a beta channel of firefox releases, you will see if future versions will contain breaking changes and give you time to react.
Cons
Con No essential tools for web development
Con Doesn't support linux
Supports only windows and mac
Con Closed source
Proprietary software makes it harder to port, study, and do further edge-case testing without breaking terms and possibly getting sued. It even makes it harder to test on multiple OS platforms, some with varying ability for rendering.
Con Heavy
Since it has a lot of tools to support debugging and web development, it is considerably heavier than the standard version of Firefox, definitely I don't recommend it for standard web browsing.
Con May be unstable
Since it is a release channel between beta and Nightly, it may be unstable.
Con Lack of support for source maps in blobs
Still a bit buggy support for CSS source maps coming from blobs. The team is working on it though, and the fixes will eventually land in the production code.
Con Not based on Chromium
If you don't want to make your website support non-Chromium browsers, this can be a problem.
Con This project is not yet available for Android
The developer edition is not available for mobile devices, though the beta and nightly channels are available, and can be used for testing future versions of Firefox.
