hello leo, on your android phone go into the system's settings app & into accounts & synchronisation (might be worded slightly different on different android devices), go to firefox sync & tap on pair a device.

on your desktop go to firefox > options > sync > set up firefox sync > i have an account which will show you a 3x4 character code that you'll have to enter into your android device in order to complete the process.

Thnx! I tried to find this in Firefox menu :-)

Sir: I have this same problem. I get all the way to the step where the 3 boxes of code show up.

I have a set of code on the computer and a different set of code on my cell.

Both say enter this code.....enter it where.???.. the boxes are full of code and neither permit me to add - delete. add any code.

Now what.???

hello CasaRuidoso, do you want to set-up firefox sync for the first time? then my steps above won't apply to you, since they cover pairing a device to an already existing sync account.

to set-up sync initially, please use the following steps of instructions instead: How do I set up Sync on my computer?
