Strip tracking params before sharing links

[gudvinr]

Is your feature request related to a problem? Please describe.

Many sites add tracking tags as query arguments. Notably, utm_* tags google uses, fbclid facebook uses, etc.
While browsers may strip these either natively or using extensions, other apps can't. So if you send links from RSS reader, you might end up with horrendous links

Describe the solution you'd like

Parameters can be stripped. I understand that manual parameter maintenance can be tedious but fortunately, there are third-party solutions available.

Firefox, for example, does this with ETP enabled (which is by default). Arguments are supplied from this URL. However, list is rather short and doesn't cover many options.

There is also an option to use filters from adguard/ublock origin which provide $removeparam option. uBlock origin serves "AdGuard URL Tracking filter" from here which can be seen in their repo.

Implementing parser for generic ad-filter lists would be suboptimal but rejecting everything other than strings starting with $removeparam and extracting arguments with /^\$removeparam=([^,\n])+$/ gives this:

These are domain-agnostic parameters which are constructed from adguard's general_url.txt.

Further improvements might include extending filter to also parse domain-specific rules as /^\$removeparam=([^,])+,domain=(.+)$/

List can be added as URL param to the settings so users might use their own if necessary.
