[feature] Support for capturing browser requests, when proxies are added through browser extensions/VPN extensions are enabled.

Is your feature request related to a problem? Please describe.
First of all, hands down! This is the best requests-capture app I have come across in my life. The features,UI and almost everything is amazing and it fulfills all of my needs, what I need in an app like this.

However, one slight problem I faced is this: Let's take chrome browser for an example. As you already may know, there are many chrome extensions which gives us the ability to add proxies/connect to a VPN through the browser. One such extension which gives us the ability to add proxies (http/https/socks), is FoxyProxy extension. However if we add a proxy through this to the browser and browse pages, the browser requests will not appear in the reqable app. I experienced this same issue when using VPN extensions in the browser too. One such extension is Hola VPN extension Same as I said above, if we connect to any location as a VPN through this extension in the browser and browse pages, the browser requests will not appear in the reqable app.

Describe the solution you'd like
This behaviour is a little weird for me because if we connect to a proxy or a VPN outside the browser through any normal application, the reqable app will capture all the requests and show them as it is supposed to do. This issue only comes when connecting to a proxy/VPN inside the browser through an extension. So I really think it will be nice if the application had the ability to capture these requests too.

Describe alternatives you've considered
There is a software called HTTP Debugger This software does not have the ability to do even a fraction of things which reqable is able to do but we can capture these kinds of requests through this app without any problem. So I really think that it will be possible to implement this feature in reqable too.

Additional context
I do not know if this should be considered as a feature or a bug. Although I hope it is not that much of an issue and you will consider this request.
