Mullvad is much better privacy wise than Librewolf, its also snappier and has faster security and privacy updates. The only thing you really lose out on is Firefox sync (if you enabled it on Librewolf). The new identity button helps you reset to a stock state and allows you to circumvent fingerprinting (such as the fingerprinting used for enforcing bans) trivially. Mullvad takes Tor Browser's approach to heart, while Librewolf takes Arkenfox's changes to heart. Its factual that Tor Browser is the most private browser, so emulating aspects of it is certainly the way to go.

Some things you will probably find annoying:

• Its so good at stock that you shouldn't customize it much if you don't know what you're doing.

• Letterboxing is hard to get used to

• Without nonstock modifications, its not suitable as a daily driver in my opinion, its a privacy tool first and foremost with stock settings. When you make it nonstock, it becomes very good as a daily driver but you really must be as minimalist as possible in your alterations. Take only what you desperately need, and make sure your settings do not interfere with the normal function of incognito mode which will essentially set the browser back to stock for you fingerprint wise by disabling cookies, history, extra addons, etc.

Some things you will like:

• Librewolf is sort of bloated feeling stock. It doesn'f feel as quick and snappy as Mullvad does.
