"Copy clean URL" feature

We currently have a privacy feature to strip out identifying parameters across sites. Users are asking us to go further and remove anything that’s not needed when copying URLs.

For example, there are first-party parameters which are not in-scope for the existing query filter:

• Amazon has URLs like https://www.amazon.com/Echo-Dot/dp/B07FZ8S74R/ref=sr_1_1?crid=1JM4ODN4MKLZO&keywords=alexa+echo&qid=1654644603&sprefix=alexa%2Caps%2C136&sr=8-1 where only https://www.amazon.com/dp/B07FZ8S74R/ is needed.
• Twitter has unnecessary t and s parameters which seem to identify the application and user who shared the link.

There are also parameters which aren’t privacy-harming but which clutter shared links needlessly.

This should be opt-in to avoid surprising users who may be thinking that Brave is broken and unable/unwilling the copy the full URL from the URL bar.

I think this pollutes the context menu unnecessarily. What about having only one “Copy Link” on context that removes trackers by default, while in the settings an option “Allow trackers on copied links” if the user wants or needs it for some reason?

On a side note, totally against editing content from the clipboard, except explicitly enabling that as an option.

@evq also pointed out that we should also debounce URLs that people copy to the clipboard. So if you copy https://www.google.com/url?q=https://example.com, for example by copying it from Google Docs or Google Calendar, then it would put https://example.com into the clipboard.

So first, aggressively debounce URLs, then strip the query string down to just what’s needed.
