Question What is Data Leak Blocker Extension on Firefox?

[lokamoka820]

When I was checking HiBit Uninstaller browser extension manager I found a new installed extension called "Data Leak Blocker", and when I checked my Firefox extensions I didn't find it, it is also shown on CCleaner browser plugins tool.

What is it? Is it installed by default for every Firefox user, or there is something wrong on my side?

These comments suggest that the extension is an internal add-on, possibly added in 143.0.1:

• 1988533 - data-leak-blocker addon release can't be created in shipit
• Glean Dictionary

I am running the 140ESR version, and it still doesn't have it.
