Tablet Pen Pressure Support for sites that use & support drawing tablets

[yota]

In whiteboard or drawing sites like tldraw & pixiv sketch where we can use stylus from a drawing tablet, the pen pressure doesn't work in Firefox.
I've included screenshot of comparison of pen pressure test using https://openprocessing.org/sketch/591905/ done in Firefox(left) & Chromium(right).
At first I thought this was issue from application/site because I don't use Chromium but I was told it's Firefox issue & testing it myself on both browser proves that.
Please include support for pen pressure as I use Firefox everyday & don't want to rely on Chromium.

I've been having this same issue whenever I try doing whiteboards or gartic phone with my friends- though instead of pen pressure, I just can't use my tablet/pen to draw at all on Firefox. My friend has the same issue, we always open a tab in Chrome just to do whiteboards/gartic. If they fix pen pressure, that might fix the general issue for drawing tablet users. What kind of tablet do you use? It could be depending on the type- both my friend and I use Huion (no screen).
