After reading your blog regarding Firefox support for "Legacy" add-ons: https://blog.mozilla.org/addons/2017/02/16/the-road-to-firefox-57-compatibility-milestones/

I would like to request to delay the removal "Legacy" add-on support until the release of Firefox 60. This allows users of existing "Legacy" add-ons to switch to Firefox ESR 59 and continue to have "Legacy" add-on support AND security updates for quite a bit longer.

I use the add-on Password Hasher (https://addons.mozilla.org/nl/firefox/addon/password-hasher/) to generate and enter all my internet passwords, and the ending of support for this add-on will be a major problem for me as I require this to login to all my website accounts. I also love to use the "Legacy" add-on Classic Theme Restorer (https://addons.mozilla.org/nl/firefox/addon/classicthemerestorer/) which is also endangered by the change.

Thank you for your consideration.

Dude, you're singing to the choir here when it comes to "requests". Very few (or none) of the people who make such decisions ever grace us with their presence. You can let Mozilla your thoughts on any topic concerning Firefox via Help > Submit Feedback ...

IMO, as far as pushing back the "demise" of Legacy extensions to the next ESR release - it ain't gonna happen. That would commit Mozilla to (close to) another year of support for those extensions; something that they just don't want to do.

But there is going to be a version of "Nightly" that continues support for Legacy extensions, but I don't recall the details.

Thanks. I also submitted the feedback form.

The current Nightly build disables Legacy extensions by default and has a pref named extensions.allow-non-mpc-extensions , but I have no idea how long this will last.
