PSA - You need to ACTIVATE weekly challenges - it's not automatic
I see a lot of people confused why their fire kills aren't being counted in Far Cry 5 for the weekly challenge.
Weekly challenges need to be activated. I'm on PC and I use the overlay (shift + F2) to bring up the Ubisoft Club and select challenges.
There is also a guide on the Ubi support website:

PS - if you have a problem with the game or a suggestion for improving it you should submit a support ticket asking for the info to be relayed to the Dev team. Complaining about stuff on the forums is one of the least effective methods to get the attention your issue deserves. Seriously the more people request additions or report bugs via the support system the more likely those items will be addressed. Or you know keep yelling into the wind... cause that's really worked well for the last few games...
