The Firefox extension is being worked on, although we wait for more APIs and such.
It is feasible in many ways, as I discussed here.
Also, depending on the implementation of the SAFE librairies in the extension, the option of farming could be more or less easy to implement.
The importance of a small farming capability is real and it’s a good way to “have a foot in the door”.
@davidswords we will gladly accept your help!
