Comment 10 for bug 1676164

Some days ago Mozilla released Firefox 57 which completely disable classic ("LEGACY") extensions. I think that real enterprise users are not happy with this new feature. Users do not need bells and whistles, they need to do their work with stable user experience and without security vulnerabilities. Firefox users can’t repair car while driving it.

The current status of porting LEGACY extensions to WebExtension are located in Google Spreadsheet (https://docs.google.com/spreadsheets/d/1TFcEXMcKrwoIAECIVyBU0GPoSmRqZ7A0VBvqeKYVSww/htmlview). The percentage of WebExtensions is not too high.

According to this fresh AskUbuntu question "How do I downgrade Firefox v. 57 to v. 56?" (https://askubuntu.com/q/977138/66509) - the problem is critically actual nowadays.
We have 12000 views of this question for 36 hours.
The accepted solution is mine: it suggests to install Firefox ESR from PPAs (jonathonf or mozillateam).

But stop and read it again. Why users should use PPAs for most common software such as web-browser (Firefox is actually default web-browser in Ubuntu)?
What will happen if these PPAs become compromised?

Debian already has Firefox ESR for all supported versions.

So I (and other users from AskUbuntu) kindly ask you (Ubuntu developers) to make official ESR package and put it alongside bleeding-edge version. You can make partnership with Mozilla Team here, I think.

I posted the similar question to the new community.ubuntu.com (https://community.ubuntu.com/t/firefox-esr-package-is-really-needed/1970).
