YouTooltip

Adds a tooltip containing information about videos and playlists when hovering over a YouTube link.

Currently supports Firefox only.

Notice: In Manifest V3 (now the current version), you will have to manually grant YouTooltip permission to run on webpages. You may either grant access to all sites, only individual sites, or only when clicking on the toolbar button.

Privacy policy

YouTooltip does not send user data to me nor use any analytics. I don't care for your browsing habits.

YouTooltip does store statistics on your computer; however, you may delete and/or turn them off at any time.

YouTooltip does make requests to either Google's API, Invidious' API, or Piped's API for video and playlist information; however, no identifying information is shared. Requests always use HTTPS. The data that is sent to the API of your choice is the video and/or playlist ID's, field options, and an API key (where necessary).

Other notes

The default API key(s) that YouTooltip uses are my own, and I have the right to disable them at any time for any reason. In addition, Google may also disable them at any time for any reason. You may choose to provide your own API key, but you are responsible for its use.
