For this part specifically, if argue you’re trusting the distro packaging anyway because they provide pretty much everything you install anyway. Whereas f-droid is a separate entity from whatever operating system you’ve installed.
The rest of your comment, about potential lag in updates and unsupported builds in case of support tickets, is spot on, though!
I felt better off with it using it when it was hardened with an easy to use script that’s well trusted. If Arkenfox dies I’ll give Mullvad a shot as my main driver, but I try to split out my internet use between two browsers, so I dunno if it would be appropriate to put all my eggs into the Mullvad Browser basket.
I hope the project finds a new maintainer. That being said, it’s not like the current version cannot be used for the foreseeable future. It’s just a user settings file and it is not security-critical in any way. I’d be surprised, in fact, if some of the tweaks are still relevant or necessary.
In any case, fighting browser fingerprinting is very much an uphill battle. Even with JS completely turned off, a far more drastic measure than anything Arkenfox does, the combination of IP + user agent is probably enough to reliably identify a large proportion of unique users.
What do you mean by “it defeats its purpose to combat fingerprinting.” ? I was under the impression that Mullvad Browser + Mullvad VPN is great for anti-fingerprinting because of PG’s recommendation?
I think what they’re saying is that the anti-fingerprinting capabilities that Mullvad browser has may make it too inconvenient to use as main browser. This is usually said about Tor.
I guess the confusion stems from labeling a browser as a “main browser”. What you consider as your main browser may not be what someone else considers as their main browser. Eg, if all you do is surf the web, I think Mullvad is just fine. If you want to stay logged into websites, though, use another browser, as @win11.shading291 said.
I suppose this makes me glad I pivoted my model in how I use browsers. Chromium variants (Trivalent/Vanadium) for logged in usage, and Mullvad Browser for anonymous non-Tor browsing.
I am pretty sure that what @win11.shading291 meant with „don‘t use MullvadBrowser as main browser because it defeats the purpose to combat fingerprinting“ is that if you use MB while still logging into websites the anti-fingerprinting is not worth anything because when logging into websites / being logged into websites, the website can uniquely indentify you anyway. Therefore, it defeats the only purpose of anti-fingerprinting.
Plus yes it isn‘t as convenient as non TOR Browser / non MullvadBrowser too.
