Default browser redirector

This script on Windows sets itself as a default browser and redirects the link protocol handlers HTTP, HTTPS, and FTP for opening links in different browsers with custom arguments.

Qualifications

• Are you a power user who uses multiple browsers?
• Do you want to keep browsing sessions separate for different websites?
• Do you want to control which websites open in which browser and in either a new tab or new window?
• Are you tired of manually copying and pasting links into the correct browser?

Requirements

• Python 3.10+
• Windows

Installation

1. In the "src" directory, run "Install default browser redirector.bat" as administrator.

2. Start > Run (Win + R) > ms-settings:defaultapps.

   Start > Settings (Win + I) > Apps > Default apps.

3. Default browser redirector > Set default file types or link types for HTTP, HTTPS, and FTP > Set default.

Config file

The script and config file are installed to the "%AppData%\Default browser redirector" directory.

The "browser_rules.json" file contains the browsers and the rules in JSON format.

The first browser will be the default browser if no rules apply.

Browser property

• Each browser provides a path to the executable. However, the "clipboard" property does not require it.
• An optional arguments property can be a single string or an array of strings.
• If the clipboard value is true, the URI is copied to the clipboard.

Rules property

• The rules property is an array of strings or objects, containing text, regex, arguments, and clipboard properties.

Regex property

• The regex property can be a single string or an object, containing pattern and flags properties.

Examples

An example "browser_rules.json" file is provided and must be edited with your custom values.

• Opera is the first browser, which is used as the default if no rules apply.
• Vivaldi opens for github.com, stackoverflow.com, twitch.tv, ups.com, and zillow.com.
• Google Chrome opens test.tld using the "Profile 12" profile.
• Mozilla Firefox opens firefox.com using the "default" profile and copies the URI to the clipboard.
• Thorium opens discord.com and Private.tld in a new incognito window and public.tld in a regular tab.
• Microsoft Edge has no rules and is ignored.
• For the "clipboard" property, clip.me is copied to the clipboard only instead of redirecting to a browser.
