Firefox... taming the beast part 2 !!

@Ghot my primary goal is to change the size of the Firefox UI itself with the about:config change and not the zoom size of the webpage. I already have "browser.compactmode.show > true" enabled but the Address Bar and Icons are still too big for my liking running a preferred system resolution of 1920 x 1080 @ 150% DPI.



Goal is to make everything in the Red box + Tabs = UI smaller forcing Firefox itself to display independently at 125 DPI while maintaining the system at 150 DPI, sorry if my post sounds confusing that's why I give never give directions (People would get lost). As you know when you change system the DPI it affects all applications.

Best I've been able to do with Firefox itself is this...
Actual size...



How I did it... I'm not sure. Everything I've done is in post #1 of this thread.


I think this is a job for @das10
He's good at... pixel adjustment. See post #294 for example.

Yeah my original intent was only to see if you already knew about the "about:config > layout.css.devPixelsPerPx > Edit > Change value tweak and if it may be useful to you or others.

Yeah, you want @das10
He's the best we got in that area. ^^

Re: the "layout.css.devPixelsPerPx" setting, I have already been using that setting (I personally set it to 1) as per post #246:

Firefox... taming the beast part 2 !!

But I am afraid I don't know how to set the size of the Navigator Bar alone as you have indicated in your image.

(pn: there are some more settings in the link in post 247 Welcome )

@das10 the "layout.css.devPixelsPerPx" setting you mention in post #246 does exactly what I want and was just happy it also changed the size of the "Navigator Bar" to my liking.

Coming soon... available on Nightly, now...
