Ask Before Opening URL on Linux

Today I opened Thunderbird to check my email, and without confirmation, it opened Firefox to a donation webpage. That's fine for Thunderbird, but I don't want any program just being able to open URLs without confirmation. This is a security breach. On Android, I have multiple browsers and no default. Whenever an app wants to open a URL, it asks me which browser I would like to use. I also have the option to not open the URL at all. How can I get this same kind of functionality on my Linux desktop? EDIT: Perhaps there is a small Linux program that I can set as default browser, and it intercepts URLs, and prompts me for a browser to open with?
