I've been using Librewolf for more than an year now, and Im using Mullvad Browser (MB) only for log into my e-mail and stuff more personal like that. Since Mullvad gives some very good filters about privacy, i'm using MB for these purposes.

However, i been thinking if i should use Mullvad Browser as my main daily driver browser. However, i need to use a dark mode/reader, since i like to have eyes and for me is super uncomfortable not using a dark mode.

I'm using the dark reader on librewolf, and i know this is make me more finger printable , but i cannot use a browser without a dark mode.

My question is if, either with a dark mode/reader on mullvad browser, this is better than librewolf in terms of privacy and security. Mullvad is more quick than librewolf in update terms , for which i search it. And other thing i know i can do, is create multiple profiles on mullvad and librewolf, to compartmentalize the things i visit / search... (for example, one profile only to check my emails, one for normal browsing, and so on.... )

and btw , on ubuntu, which is the better way in terms of security and privacy, to install the mullvad browser? via .deb ? snap? flatpak?

ty in advance
