I welcome the change to the new technology, but as many dev make add ons in their spare time, could you make some incentives for them to update to the new tech?
With the new version of today, 55, the Firefox browser is greatly faster, but many of my add ons, which are a crucial part of my browser experience are of the old technology and will sease to work after 57. As many of the developers write their add ons in their free time, I think for a smoother transition you could make some incentives for the developers to update or hire developers yourself that help the add on devs to rewrite and renew their code to fit the future versions.
I really hope you consider that as me and many other Firefox users are already freaking out at the perspective that many of the add ons will be incompatible in november.

Lots of add-ons are already compatible with Firefox 57, and many more have add-on developers are working hard to make sure they have compatible updates out in time for 57.
Unfortunately, this breaking change needs to happen. It's something we've put off for many years, and announced over a year ago to make sure that developers have plenty of opportunity to upgrade. This change will actually make it easier for add-ons to work in Firefox in the future, as once they are using webextensions the chance that a Firefox update will break your add-on in weird ways becomes less likely (In theory, it wouldn't happen at all but you never know). Now that things are moving to this new ecosystem, then we will be able to provide a better environment for add-on devs in the future
There are quite a few add ons that will sease to work,
I will especially miss Roomy Bookmarks, except if Mozilla considers integrating its function to Firefox 57 https://addons.mozilla.org/de/firefox/addon/roomy-bookmarks-toolbar/?src=userprofile
I really got so used to it
Is there any way to make a suggesion to Mozilla Dev to integrate something like Roomy Bookmarks into FF57?
BTW, I see this issue is coming and many Firefox users will either stick to the old version (which no security conscious person would do) or move to another browser, because the problem of many add ons failing will create conflict for many users who, like me, appreciate the Firefox ability for a wide range of modification. This issue hasn't been resolved because not only every addon dev have the time to completely rewrite their code, but also like in the case of "Roomy Bookmarks" according to the dev, what he has written on the add on site is that the new technology is restrictive in that it is impossible to transfer the add on.
I've been a user of FF since day one (literally) and if that issue isn't resolved, I probably will have to change to Chrome.
