Ask HN: One feature that you wish Mozilla didn't remove from Firefox?

Privacy.

Silently opting users into ad telemetry data collection is pure evil and makes me sad to see, given how awesome and pro-indidual M used to be.

There's "Open Image in a New Tab" so "View Image" is not "really" gone: https://bugzilla.mozilla.org/show_bug.cgi?id=1690030

- FTP

- Syndication feed (RSS/ATOM) "sniffer" (or whatever the hell it was called).

I know that's 2 things but I couldn't choose between the two in enough time.

The workaround for firefox extension is to use firefox developer version with addons collection.

Last I checked about:config did not work for me on stable android firefox .

There was no reason to remove ftp.

The ability for add-ons to customize the GUI/Chrome!
