Browser Tamer

Why

Browser Tamer acts as a browser proxy on your machine that catches links you click and redirects them to a browser or browser profile of your choice.

The main difference comparing to other products is that it’s tiny (less than 1.5mb exe, ~2mb RAM), completely free, blazing fast, and never uses more than 0% CPU or any CO2 (makes it good for the 🌎). It works on green energy and even the oldest hardware you can find. It also does not track you.

Installing

You have a few options:

• direct download (installer or portable)
• with winget: winget install IvanG.BrowserTamer
• with scoop: scoop install bt

Then launch main executable, configure rules, and it’s ready to use. In order for Windows to redirect all URL clicks to Browser Tamer, you need to set it as default browser.

BT needs 3 protocols set as default and displays the status in the status bar on the bottom.

If any of them is not default, you will see them highlighted in red and a status message saying “… protocol is not handled by Browser Tamer, interception will not work!”.

Unfortunately, Windows 11 made it more convoluted to change default browser from user interface, but it’s still easy to do.

In order to get to the default browser configuration in Windows, you can follow a shortcut by going to Tools, Windows Defaults.

This will open different windows depending whether you are on Windows 10 or 11. Microsoft provides official instructions for Windows 10 which are trivial to follow - just pick Browser Tamer from the dropdown menu. Or in case of Windows 11 windowscentral.com has a good guide to follow too. I might find a way to set default browser automatically, but Microsoft actively prevents external programs to do that without user interaction for now.

Configuring

Default Browser

By default, BT takes the first browser it finds and opens all the links in it.

Default browser is highlighted in red in the browser tree in the configuration interface (see picture on the left). In this case it’s set to aloneguid@outlook.com profile inside the “Microsoft Edge” browser.

To change the default browser, just find the profile you are interested in and press the “heart” button (see arrow pointing to it on the picture).

The only case when default browser is not used is when an URL is matching one or more rules (see below) or you are picking a browser manually (see below).

Rules

All the links that do not match any configured rules will open in the default browser, however that’s not very interesting and not why you installed this utility in the first place.

To open a link in another browser, you need to create a rule.

A rule is a single line in the Rules section. It simply says that if a link contains text you’ve typed in, then open the specified browser. It is case insensitive so a line mydomain will match mydomain.com, MyDomain.com or https://blabla.mydomain.com.

You can keep adding as many rules as you want, they are always case-insensitive and match any part or the URL.

Picker

Picker is a visual prompt that asks which browser you want to open a link in specifically, instead of matching a rule.

To open the picker, hold ctrl and shift buttons while clicking a link to display a window similar to this:

Then simply click the browser you want. Browser Tamer also remembers how many times you have picked one browser or another, and sorts the presented choices in that order.

Picker is also shows automatically when more than one rule is matching a specific URL.

Supported Browsers

All the browsers known to the world are supported. Out of the box Brower Tamer detects:

• Mozilla Firefox. Including private mode.
• Microsoft Edge “Edgium” (Windows 10/11 default). Including profiles and incognito mode.
• Google Chrome, including incognito mode.
• Brave.
• Vivaldi.
• Opera.
• Other browsers based on Chromium or Firefox may be autodetected as well, as they register themselves in the system in a similar way. Users have reported successfully using Slimjet, Avant, Chromium as well but I suspect the actual list is way longer.

And if that’s not enough, you can always add your own custom browser if it’s not discovered or installed in an unsupported way (like a portable install). Note that scoop is famous for screwing up browser installations, so most probably you will need to customize it in some way.

Browser Extensions

You can optionally install an extension for Chrome that help to redirect links from inside the browser to local instance of Browser Tamer.

FAQ

Export/Import Configuration

Starting from v2.7.2 configuration is stored alongside bt.exe in bt.ini file. You can back it up and restore on the same machine or with some luck on a different machine.

Prior to v2.7.2 configuration was stored in the Windows Registry. If you have to export current configuration to a file for memories or just to back it up, you can still do that:

reg export "HKEY_CURRENT_USER\Software\Browser Tamer" backup.reg

reg is standard command, that will create backup.reg file you can import elsewhere or just open in text editor. To import later use reg import.

Version History

Note that VirusTotal reports BT as malware, and here is my explanation why. It’s totally up to you.

Since v2.5.4 I’m also uploading installers, mostly to increase the reach on platforms like winget as they do not accept portable uploads. There is no other reason to use installers, they do not do anything other than copying files.

Thanks! You can always email me or use contact form for more questions/comments etc.
