Most of these browsers use the enterprise policy of chromium.

For a year, but it will be extremely difficult for them to maintain mv2 after jun 2025.

Proton is great but I do feel wary from putting all my eggs in one basket again.

Definitely Syncthing.

Great app to sync my phone with my laptop.

Seems like a good browser. The only issue is how maintained will it be. Also, librewolf has been released and maintained properly and is proven time and time again. Not sure how different it is from LW.

One solution that comes to mind is Odoo

But you will have to check it and see if it has the things you look for.
