Mozilla revealed recently that it would integrate Hyperlink Ping Tracking in the Firefox web browser and enable it by default.
Simple Ping Blocker is a new browser extension for the Firefox web browser that blocks any pings from being sent when links get activated in the browser.
It is quite puzzling that Mozilla would enable ping tracking in Firefox by default without user safeguards. Options could include highlighting links with the Ping attribute in a special way, displaying a prompt to users when they first encounter Pings, or better yet, disabling the feature by default but asking users whether they would like to opt-in when it is encountered.
Ping is not enabled yet in Firefox and the add-on does not do a thing right now because of that. You could bookmark it to keep it in reach or install it and deactivate it until Mozilla enables Ping to activate it.
Note: uBlock Origin users don't need the extension as the content blocker comes with Ping blocking functionality. Chrome or Chromium users may also install Ping Blocker.
