Mullvad Web Browser: Can its advanced privacy features cause harm for the user?

Good morning,

Could a website detect a user who is using a browser that’s particularly strict on allowing what the website can and can’t learn about the user and then restrict the content of what that user is able to see on the website. E.g a user using Mullvad browser?

I’ve never used Adblock or any other ad blocking technology because I’ve always been paranoid about websites altering what I view on their web sites because they’ll detect I’m using some kind of ad blocking technology.

Youtube has been slowing down videos of users who are running adblock technologies. Could this happen with other websites as well?

In other words, can too many privacy protections in a browser actually harm the user and prevent or limit them from accessing 100% of the content on the website or as YouTube has done, by slowing the browsing experience?

Thank you for reading my question!

Edit: I just changed the topic to specify Mullvad Web Browser and not Mullvad the VPN.

if you define harm as websites being shit if you don’t let them invade your privacy then sure, privacy protections can be harmful

i guess it also partly depends on your threat model, whether accepting random sites trying to fingerprint you to not get content hidden is worth the tradeoff

Yes they can. Many sites block Tor Browser. But, IMO, the risk of websites changing content based on browser adblocking is much less than not blocking ads and trackers. Also, most websites don’t do this because it ends up being fairly resource intensive to do this and without clear benefit to the website (except perhaps in some cases such as YouTube or other media sites). You are much better off just using Mullvad Browser or uBlock and firefox than not.


Article of what I mentioned:

I’ve never even tried the Mullvad browser because of this fear. I’d really like to try it as it’s so popular here, but this fear holds me back.

Firefox is my main browser.

You can always just try it! It’s free and you can easily uninstall it if it doesn’t fit your needs. Outside of any website breakage concerns (which you can always test for yourself by just browsing with it), the other thing I’d keep in mind is that you probably don’t want to entirely replace Firefox with it, as it’s not good for stuff you need to stay logged into, given it clears everything on close. I use it for pretty much everything that falls outside of that category (quick searches, opening links sent by others, etc.) and it works great alongside Brave for the things I need to stay logged into or where a browser history is a genuine positive (longer research sessions etc.).

It was an adblock-plus issue.

Again, as everyone here point it out. Only use uBlock Origin.
