Hi

With regards to Linux, there are two "versions" of Firefox, the one you can download from Mozilla or the version that came with, or that you can download for, your Linux distribution.

If you are using a Mozilla version, you should have the data choices when you go to about:preferences#advanced and look under Data Choices. If you are using a version from your Linux distribution, these choices may not be there as the "distro" may have decided to make some changes in getting Firefox ready for Gentoo.

I am glad to hear that you are interested in providing telemetry data, this helps make Firefox better. I recommend you take a copy of your Firefox profile (details as to how to do this can be found here) and download a Mozilla version.

I know that Ubuntu recently changed its versions of Firefox so that they provide telemetry, and possibly if you feedback your experience to Gentoo, they may consider doing this as well.

I hope this helps, but if not, please come back here and we can look into a different solution for you.

Seburo, thank you for the quick reply.

I am using the Gentoo packaging system, Portage, provided Firefox. (Acutally it provides Firefox source-code, patches, and instructions so Portage can automatically compile Firefox on my system. Takes about 30 min. to compile.) I've posted on the Gentoo forums, I wonder what happened between Firefox 46 which had the telemetry data choice and 47?

Hi

If this is a packaged version, the people that work on Firefox in Gentoo will have the answer to this.

Until I moved to using a very early test Mozilla release of Firefox, I was using a Ubuntu package and the move to include telemetry data in that package happened very quickly. Chances are Gentoo could do this as well.
