But this is the SUPPORT MOZILLA forum.

Yes, it is tech support. "How to." That's within the limits of the product: settings, add-ons, workarounds, etc. Support cannot address issues like:

• Whose idiotic idea it was without giving us the OPTION of single OR double padding??
• Why do we have to look online for the hacks and workarounds to remove this most idiotic and controlling change??
• Please bring the single padding back NOW or I will completely switch to Chrome or simply will stop updating firefox!

What is the feedback/communication channel directly with the Mozilla DEVELOPERS?

It's on the Help menu within Firefox: Submit Feedback. That takes you to the site where you can find a lot of feedback has been given on this issue already. Tightening up menu spacing is one of the most popular ideas on the site: https://mozilla.crowdicity.com/post/720482

Ok, so that's the feedback. What about communication?

Submitting feedback, which is what this forum does indirectly anyway, is not "communication".

"Communication" is a two way street: the sender sends a message and then the receiver replies to it.

People can post their "feedback" on the City Hall community board or on the nearest lamp post with the same effect as posting it on a site that accepts feedback with no reply.

I am not interested in proving feedback - I am interested in having my questions answered which is communication.

It's like Facebook - you can submit all the feedback you like - you will NEVER receive a reply addressing your concerns or resolving your technical issue, unless you are reporting fraud, misconduct or breach of privacy and security.

No wonder people are leaving Facebook in droves.

Hey there!

Please see https://support.mozilla.org/en-US/questions/1342447 for how to remove the double spacing.

Hope I helped!

Kind regards,
