Chrome to Firefox is a relatively easy switch, especially for those that don’t depend on Google sync. The main sources of friction for me were the lack of a good profile switching UI (solved with a browser extension that mimics the Chrome menu), and weird security requirements for homemade extensions (IIRC if you want to have the extension persist after restarting Firefox, you need to sign the extension, which is a pain)

For users switching from Arc, there is no good alternative, but Firefox with Sidebery and custom CSS comes close.

I love Mozilla, but I’m concerned about its future. Since 80% of its income reportedly comes from the Google search deal, do they have a plan to replace it after the recent ruling? And can they maintain their current level of autonomy while doing so?

uBlock Origin + Multi Account Containers makes Firefox enjoyable to use.

Main reason I'm still using Chrome and can't switch to Firefox: https://connect.mozilla.org/t5/ideas/feature-suggestion-fire...
