All snark aside, Firefox is probably the last browser you should use if you care about extensions (or other functionality) not being broken on purpose or arbitrarily removed with no notice, recourse, or opportunity for feedback.

Firefox has done this to me multiple times. As someone who uses a web browser as a tool for both business and pleasure, and as someone who does not appreciate flag days forced on me for no good reason, I am perfectly happy and have been encountered far fewer surprises with a chromium fork.
