While Firefox has many small imperfections compared to Chrome, the big point IMO is that Firefox is not preinstalled on any large consumer OS/device besides Linux.
It has many little details that aren't as good as Chrome but I don't know how much that affects adoption. Even if it does, that last bit of polish is very expensive to fix and they would need users or another mechanism to fund it.
I would focus heavily on getting Linux to be more mainstream. There is already growing momentum behind Linux and a lot of room for organizations (like Mozilla) that can typically execute on long multi year strategies better than the anarchy of FOSS. There's a lot of work to be done on all levels - partnerships, marketing, technical, finance etc. so people in all roles could contribute.
Maybe that would even play out outside Mozilla, like people leaving and joining other companies that push OSS ahead until it gains enough users for Mozilla to be relevant again.
