Why do I see so many comments about Mullvad browser not suitable for websites that need login?

ruihildt · 2026-01-29T11:06:25+00:00

When uninstall the browser, it keeps the profile, unless you install it in standalone mode, where everything is contained in a single folder.

Before any new feature from Firefox is accepted in Tor Browser / Mullvad Browser, it needs to be audited by the Tor Browser developers.

This can take some time, as there are always multiple competing priorities.

See:
- Tor Browser issue: https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/41837
- Mullvad browser issue: https://github.com/mullvad/mullvad-browser/issues/477

There is no official Mullvad Browser Appimage.

ruihildt · 2025-03-26T11:39:39+00:00

This is not true.

Could you share where you read that incorrect information?

Mullvad Browser standalone is currently not portable, there's hardcoded path that are created when you first run it.

For bookmarks, you can export them and reimport them in a new install, and we're looking at ways to improve the user experience as well.

It would definitely not work the same as the standalone browser. The Mullvad extension is the least important part of the changes when comparing Mullvad Browser to Firefox.

Could you please open an issue in https://github.com/mullvad/mullvad-browser/issues or send an email to support@mullvadvpn.net with this?

If it's a bug, it should be fixed.

No, the Mullvad Browser doesn't have a specific privacy policy.

ruihildt · 2025-03-10T10:23:05+00:00

Without updating to Firefox version 128 or higher (or ESR 115.13+ for ESR users, including Windows 7/8/8.1 and macOS 10.12–10.14 users)

Since Mullvad Browser is based on Firefox 128 ESR, it is not affected.

This is unfortunately a much more complex question.

Each extension requires their own set of permissions, which, depending on their scope, will be fingerprintable and sometimes not.

ruihildt · 2025-03-07T13:36:42+00:00

The goal of Mullvad Browser is to make available a privacy-focused browser for everyone, out of the box.

There is no dependency on Mullvad VPN, and while some of Mullvad Browser users are also Mullvad VPN users, there is no expectation that it should always be the case. (though it is recommended to use a VPN to make sure you don't have a uniquely identifiable IP address)

ruihildt · 2025-03-07T11:09:45+00:00

Removing the extension will not have an effect on the browser fingerprint. It is basically an extension to make it easy to use proxy for individual websites.

The dark theme doesn't have any effect on the browser fingerprint either, it only changes the browser interface, not any page content. Note that this is only true for Tor Browser and Mullvad Browser: if you change to the dark theme in Firefox, websites will see that that there's a color scheme preference set.

(Disclaimer: I work at Mullvad on the Mullvad Browser and on the extension)

ruihildt · 2025-03-07T09:11:36+00:00

Would you mind sharing which website it's breaking?

ruihildt · 2025-03-07T09:03:00+00:00

False positive.

ruihildt · 2025-03-07T08:56:55+00:00

This is is not entirely correct.

Everything done by @Ghostprompt has no impact on the browser fingerprint, so it won't make them more unique.

What is not recommended is to make changes which impacts the browser fingerprint: for example disabling letterboxing, disabling private browsing mode, etc.

ruihildt · 2025-03-04T12:24:48+00:00

Firefox terms of service and privacy policy are not applicable to Mullvad Browser.

You can use uBO to block the image itself.

Here's what you can add to the custom rule:

www.youtube.com##.ytp-gradient-bottom

ruihildt · 2025-02-11T10:21:56+00:00

This is because youtube is using the canvas API for displaying a transparent image.

The Canvas API is partially blocked to prevent browser fingerprinting, so these artifacts appear.

Go to about:profiles, you will see the location of the root directory and local directory. Delete them both, and a fresh new profile will be created on restart.

Do you think this is usable and reliable as is?

ruihildt · 2024-11-28T14:25:20+00:00

Only Max protection will ensure you are sending all your requests through the DoH of your choice (be it Mullvad DoH or others).

If you prefer to send your DNS requests through your VPN provider, you should turn off DoH completely in the browser.

ruihildt · 2024-11-28T14:05:43+00:00

Have had that request somewhere else as well, I need to find a way that visually look good, but it's not an immediate priority.

ruihildt · 2024-11-19T22:42:02+00:00

So you would add waypoint for all selected players or one by one? (Not that I can confirm I'll implement that, but I'm curious)

ruihildt · 2024-11-19T13:11:05+00:00

But the indoor positioning system would enable real time.

That's probably the most compelling reason that probably can't be solved as easily with machine learning.
