This is the direction we should be moving in.
Bravo.
It's great to see, but ClearURLs works better for me so I use that more.

It would be even better if it would do that automatically when hitting Ctrl+C in the address bar.
As someone who cares about privacy but has the intelligence of dirt, what does this do?
URL's can have tracking/surveillance/data harvesting codes appended to them. This option removes those.
I wish it was a bit more aggressive. For that I have an additional plugin ClearURLs (as linked by someone else in the replies BTW), but don't know if its actually better or not.
It is pretty lame. I have a far more aggressive one written in python that I use in a shell window. One of these days I want to rewrite it in JS and turn it into a firefox extension.
It's the bane of being built-in. You don't have an extension page to explain to people that the link might not work anymore. You certainly also can't assume that your users should know of such a possibility, because this can be clicked by any user.
I guess, there could be like a workflow where it opens the URL in a new tab and asks you, if it still works, but that's also a good way to ensure your less techy users will not press that button again...
Nah, the Firefox thing just seems to have one or two rules, like remove utm_whatever=something parameters. If you expand that to 10 or 20 rules, some of which are site specific like cleaning ALL the parameters from ebay links and doing some similar rewriting with Amazon links, removing gclid and fclid from everything, retrieving the content of a few of the more common link shorteners and cleaning -that- up, etc., you can get a much less trashy experience with maybe 1 page of code. Adblock already does some of that with its site filtering. You don't get everything, but a little bit goes a long way.
Well, apparently this is the list of parameters it strips: https://searchfox.org/mozilla-release/source/toolkit/components/antitracking/StripOnShareLists/LGPL/StripOnShareLGPL.json
That would be rad if you did.
Never cleans it the way I want
I assume this strips the utm parameters?
Yeah, and a few other such parameters where it's pretty clear that they're only used for tracking.
I don't think it strips UTM parameters specifically - I think it's limited to parameters that track you individually?
Hmm, apparently this is the list of parameters it strips: https://searchfox.org/mozilla-release/source/toolkit/components/antitracking/StripOnShareLists/LGPL/StripOnShareLGPL.json
So, yeah, it's only some of the UTM parameters (+ some non-UTM parameters).
And you brought the receipts too :) Indeed, looks like it's blocking the ones that might potentially identify you, not more generic ones (like utm_content=top_banner or whatever).
