Cant get Firefox to use other GPU

[GrayK1tsun3]

I have an R7 260x GPU and I recently bought a GTX 970. I'm using both of them without SLI or Crossfire so I can get Firefox to run on the weaker R7 260x while I game using my GTX 970. I got the game to run on the 970, but I cant get firefox to use my R7. Firefox runs on the 970. No matter what it will not use the R7, so the R7 just sits at 0% while my 970 is struggling at 100%. anyone have any ideas how to fix this issue? help would be much appreciated. thanks.

Mixing AMD and NVIDIA GPUs is not recommended. The drivers can be difficult to get right.
