I have a good number of add-ons enabled and more disabled than I can count on my Firefox Sync account. I need my toolbar layout synced with my Firefox Sync account so I don't have to re-arrange everything on my toolbar the way I want them to be to each time I get a new device or need to reset one of the devices I have. Additions to Firefox Sync are surely what I want the most added to Firefox for Windows, macOS and Linux here today, September 27, 2018.
