Do this! I procrastinated on switching from Chrome to Firefox for several months because I wasn't sure how much time and effort it would take. I set up a monthly donation to Mozilla during this time because it was easy and supported browser diversity.

When I did finally switch, it turned out to be pretty easy and fast to transfer my bookmarks and passwords to Firefox, and there are some features like the built-in containers and add-ons like Tree Style Tab [0] that I find pretty valuable.
