Maintenance update.

The "Did we get it wrong?" links now open the feedback form on reallyfree.app directly, with the site and the dot colour already filled in, instead of handing off to a mail client.

Internal: the seal tooltip is now built with DOM methods instead of an HTML string, and the add-on declares its data collection categories for Firefox 140 and later.

First public release on AMO.

ReallyFree marks search results with a coloured dot so you can see, before you click, whether a "free" site is really free: green means really free, yellow means there's a catch and we name it, red means it costs money, grey means we could not tell. Click any dot for the reason.

No account, no sign-up, no email, no payment. The extension does not send us the words you type into a search engine — only the addresses of the results shown on the page, so the verdicts can be looked up.
