Send Tab URL by Kevin Sangeelee

This add-on serves two purposes.

By default, it lets you submit the current tab's URL to my server for inclusion in a search engine of non-commercial sites that I'm building . If you find an interesting page, you can easily submit it with a single click (no click-bait or social media though, the search engine is designed to discard this automatically).

Alternatively you can configure the add-on to submit to any server you choose, as long as your GET request handler sets the appropriate CORS header. So you can use it to build your own personal database of interesting links.
