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 would suggest zen browser [1] for those people.
Note that Firefox profile management is getting an overhaul right now, including an easy profile switching UI. I'm not sure when it will be landing in release, but it is being actively built!
I've tried to switch from Vivaldi to Floorp and there is some things that Firefox does that drive me absolutely nuts.
The main one is the behaviour of pinned tabs. Pinning in Firefox turns it into an icon that is harder to hit and doesn't even protect it from closing. This makes them essentially useless, they should be moved to the front of the tab bar and be protected from closing.
The second is that when you use vertical tabs the tab bar acts like a title bar instead of a separate entity. This means you can't double click to create a new tab, and trying to drag a tab often results in the entire window moving. I have to use Tree style tabs and disable the normal tab bar completely to prevent this.
There are also things that I don't like such as how downloads are handled and I've has issues with my session tabs being saved properly.
Profile is already available in Firefox(before chrome implemented it). Details on how to use it: https://support.mozilla.org/en-US/kb/profile-manager-create-...
Also in chrome, multiple profiles need multiple google account(If I understand the UI correctly)connected, but in Firefox no account is needed.
Arc has a built-in adblocker, so it depends if you're tied specifically to uBlock Origin (non-lite) features.
I'm not sure what other extensions would be broken in Manifest v3.
One feature that is missing, removed, from Firefox is PWA's/running sites as apps. This is super handy for low trust apps
I don't know much about Arc. But Arc users could give Firefox "Nightly" a try to preview new features coming up. It has vertical tabs and you can "pin" a few tabs at the top. Nightly also has containers already built-in, so you can have multiple accounts open for the same site in different container tabs.
In the past I've had a lot of issues with Google properties not working properly on Firefox -- either outright broken or using crazy amounts of CPU on Firefox but not Chromium-based browsers. Does anyone know if this is still an issue? I'd love to try again before I'm forced to by uBO breaking.
Firefox containers are amazing
I've been using Floorp for a while to get proper vertical tabs.
I don't know if this is what you meant, but as an alternative to profile switching, there are Multi Account Containers [1]. It allows assigning a container to each tab, and the containers are isolated from each other. If you have an MS or Google account for both work and personal, you can open them at the same time in different tabs.
