Allow Mullvad Browser to be set as Default Browser

[robinkleem]

Firstly, thank you for providing an important tool in the ongoing fight for personal privacy.

Due to the current installation method, Mullvad Browser can not easily be set as the default browser for a operating system. That is to say, Mullvad should be the browser that launches when URLs are clicked in applications running on the Operating System.

While the approach required will likely be different from OS to OS, I would imagine that if a viable approach can be found for Linux, Windows and MacOS, it would help with the day to day usage of the browser.

With regards to Linux, if the app was packaged as a Flatpak it would likely be identified by the OS as a acceptable candidate for default browser. In a sense, this is similar to Issue #6

Please accept my apologies for clumsy writing as English is not my mother language.

speaking from a windows experience - I use firefox portables a lot, and TB of course. These are not installed - they are simply unpacked and the option in the UI does not work (because it points to the firefox.exe and not the wrapper or portable.exe - and you end up creating a new default profile). In order to set a portable as default, you need to hack the registry.

I don't think this is something that will ever be addressed, it's been a known issue upstream since day 1 - for example https://gitlab.torproject.org/legacy/trac/-/issues/12763

I think you can run ./start-mullvad-browser.desktop --setDefaultBrowser to set Mullvad Browser as your default browser.

Which OS are you on?

On MacOS you can easily set as default browser in settings.

macOS is the exception here. 🙂

Hi. Thank you for the suggestion. I tried it and it did not work. I am running Linux (specifically Ubuntu 22.04).

Thank you for the insight. I understand the comments and perspectives of the posts that seek to isolate the browser as much as possible from the primary OS. However I still think that enabling this functionality would allow for a nice convenience trade-off and a set-and-forget configuration that would allow all future links clicked somewhere in the OS or applications to launch in Mullvad Browser without any thought.

This takes me back to the consideration of packaging Mullvad Browser as a flatpak which would then allow people to self-select the small convenience vs privacy trade-off.

But then of course then there is the need to support multiple package formats which the devs would understandably want to avoid.

No clear solutions, but I still think the ability to enable Mullvad Browser as the default for the OS would be a boon for many.

Hi. Thank you for the suggestion. I tried it and it did not work. I am running Linux (specifically Ubuntu 22.04).

Try this:

1. Open a Terminal and download the latest release for your current user:

   cd ~/.local/share && wget https://mullvad.net/en/download/browser/linux64/latest -O mullvad-browser.tar.xz

2. Extract the content of the downloaded file into a mullvad-browser folder:

   tar -xvf mullvad-browser.tar.xz mullvad-browser

3. Delete the downloaded tar.xz file as you don't need it anymore and enter the extracted folder:

   rm mullvad-browser.tar.xz && cd mullvad-browser

4. Launch Mullvad Browser with the --register-app flag, this should register Mullvad Browser as a desktop app for the current user:

   ./start-mullvad-browser.desktop --register-app

https://retiolus.net/posts/how-to-install-mullvad-browser-on-linux/

[ghost]

4. Launch Mullvad Browser with the `--register-app` flag, this should register Mullvad Browser as a desktop app for the current user:
   `./start-mullvad-browser.desktop --register-app`

thank you, it works on arch for me

[iferca]

I was able to --register-app and to set Mullvad browser as default browser in Linux (Pop OS) using something like this:

xdg-settings set default-web-browser start-mullvad-browser.desktop

But the prolem @robinkleem mentioned in the original report regarding not being able to open a link with existing configuration still persist. I can get mullvad browser open when clicking a link, say in the terminal, but the link is not passed to the browser.

Have anyone solved this issue?

[Ylevo]

One solution is to use a URL router software such as BrokenURL as default browser, which allows you to set what browser to use on a software or even domain basis.

Do you know any alternative to BrokenURL for Linux?

[AutonomousCat]

I don't trust BrokenURL considering it's not FOSS.

Here's a Windows registry tweak for Tor, however it's from 2015 so it's likely outdated. https://tor.stackexchange.com/questions/4125/setting-tor-browser-as-default-browser-in-windows

Is anyone reg-savvy enough to modify this for Windows 10 and Mullvad Browser?

[Victor239]

Do you know any alternative to BrokenURL for Linux?

Junction, it's available as a Flatpak. However note it works best with other Flatpak-based browsers, if you use it with non-Flatpak browsers then it'll open the browser but not the webpage itself.

Thanks a lot for the tip. MB is available on Flathub, so I installed it from there and with Junction it works fine (Pop OS 22.04).

[FeyrisTan]

Anybody figured this out yet for windows? I can do it when having a second browser installed via regedit. But I don't really need a second browser.

[Thorin-Oakenpants]

just right click html, htm, pdf if you want (etc), for each filetype

• choose open with > choose another app > choose an app on your pc > browse for path\Mullvad Browser\Browser\mullvadbrowser.exe , click always and be done with it

* choose `open with` > `choose another app` > `choose an app on your pc` > browse for `path\Mullvad Browser\Browser\mullvadbrowser.exe` , click `always` and be done with it

That doesn't fix clicking a url outside of the browser and it opening in not Mullvad Browser fyi

[Thorin-Oakenpants]

true :) I actually registered my portable FF as a program, and may have modified reg entries to point to FirefoxPortable.exe instead of firefox.exe (if you directly start firefox.exe it doesn't know where the profile is and creates a new one - you won't have this problem with mullvad)

TBH, I'm sure exactly what I did on win11. I already had installed firefoxes (nightly, dev) so I may have piggybacked on them

I am not vouching for these links, I already had a RegisterFirefoxPortable.exe from many years ago

• yes, I used this on Win 11
• https://www.winhelponline.com/blog/register-firefox-portable-with-default-apps/
• https://portableapps.com/comment/249909#comment-249909
• it's basically just a bunch of reg entries

I can do it when having a second browser installed via regedit. But I don't really need a second browser.

which means you know how to do it already. Having a secondary browser installed is no big deal IMO :) In fact it's very handy

[steel-steven-87]

Has anyone from the team looked into this? I have the same issue. I can't seem to find a way to set this as the default browser in Linux.

[AutonomousCat]

I just had a thought.

I understand the primary answer has been essentially - "upstream thing", but considering Mullvad Browser isn't within the exact same scope of Tor, I think it would make sense to stray from that where it makes sense.

[AutonomousCat]

I'm also curious if there's been any other Tor upstream things that have been overridden. Is #70 one of them?

[ruihildt]

Has anyone from the team looked into this? I have the same issue. I can't seem to find a way to set this as the default browser in Linux.

@steel-steven-87 This is indeed something we're looking into.

See: https://gitlab.torproject.org/tpo/applications/mullvad-browser/-/issues/87

[ruihildt]

@AutonomousCat We will do things differently from Tor Browser where that makes sense.

The next major release will contain an updated Search engines list.

[BlackRock-99]

It is very weird that this feature is deactivated. Looking forward to seeing it back

[benn125]

Setting browser as default through manually editing Windows registry... Mya, it's a so-so approach. I even prepared a .bat script for this. But, that's not really the way it should have been...

Really hope that the default browser setting can be made available in the near future, all browsers have this option.

[ruihildt]

As mentioned previously, this is planned.

[AutonomousCat]

Any ETA?

[Kenny606]

Note I generated this reg file by dumping the keys created by the FireFox Portable VBS script I modified for Mullvad Browser. So you can modify the reg file above OR use this VBS script, you obviously don't need both.

Here's a a .reg file from Windows 10 that should work find on 10/11 that should work fine. Obviously you'll need to replace the file paths to reflect your setup.

I take no credit for this script, it's simply the one Thorin pointed out previously which I adapted to my needs. However I did fully review script for anything unneeded and everything looked good to me. Tested it on Windows 10 with both the REGISTER and UNREGISTER functionality.

Instructions: Save code to .vbs file in root of Mullvad Browser folder then double click on the VBS. If the script is sitting in the wrong folder and can't find the Mullvad exe it will simply error out make no changes.

I'd like to show support for this issue. I am playing with Mullvad after having used Brave or other Chromium forks for years and I am pleasantly surprised to see that FireFox has made their browser considerably faster, more resource efficient. However, despite switching, I still have to copy+paste URLs over from other browsers when I click a link on any other application, which sort of defeats the purpose.

My biggest problems with it have been that Mullvad is too close to the Tor browser, which is portable and is designed for people whose personal safety may depend on the browser not exposing them or allowing them to be tracked. However, on Mullvad, it has been difficult to turn off some anti-fingerprinting settings which are required to actually use it effectively (such as U2F keys).

Mullvad would benefit from having an installer with two standards of security: "I want a private browser" that is a standard installation ready for work out the box, and "My life depends on it" which is more strict (and honestly you should just be using the Tor browser anyways).

Thanks!
