I actively tried to switch to Firefox this year, but couldn't due to issues with saving tabs on sudden shutdown. Due to a separate issue, my apple laptop was crashing and restarting a couple times a week. Several times Firefox was not able to restore the browsing session, and I lost all of my tabs :(
All of the browsers (including all of the Trident based ones) have had this issue for me. Most of my browser hopping in the past was driven by losing a session, being unable to recover it, and moving on to the next browser hoping it is more stable now.
Nowadays I aggressively save to bookmarks. Still a lot of tabs open, though.
