I put some data into
storage.sync and can read it from the same device. On other device I have logged in with my firefox account, on both devices I have checked “Addons” flag in sync settings and then pressed sync button (this one) on both. After this I can read my data on the first device but on the second
storage.sync is empty.
Both firefoxes are desktop versions. How should it be done?
And is it ok that reference said I can store up to 100KB but I managed to put and read almost 5MB? (still on the same device)
