Yes, I think this came up in the developer meeting on Friday.
As you can see below, it's gone people. Removing and re-adding it's not going
to bring it back. You can blame upstream.
well, I worked on abrowser quite a lot but got into big issues
the system that we use for the privacy settings pannel on about:newtab has
been removed upstream
the replacement requires a whole rework of the feature
it is far from trivial
so I think we should just release without that feature for now
it also cannot be reimplemented as an extension
I think we need the updates to the package just for security sake
and we will have to work on the feature replacement whenever
