How to enlarge firefox ui without enlarging websites?

I use 125% dpi in windows so everything is nice and big for me but Fx ui is too small. Fiddling with layout.css.devPixelsPerPx does help, wetting it to it's default -1.0 state makes every website and images on them out of proportion so it has to be manually set to 1.0, that makes websites display at 100% dpi but it also makes firefox display at smaller ui size. I want Firefox UI to become bigger, is there some addon for that or ADVANCE measure via about:config for this?

PS: I don't look for noob advices PS2: I'll add image comparing windows menu sizes and MS Edge Ui size with websites at 100% dpi compared to firefox. I wanted to upload the image here but since it doesn't work here is a proper link to imgur for it: http://i.imgur.com/79TQqDM.png

Type about:customizing<enter> in the address bar. Look for Show / Hide Toolbars at the bottom left.

There should be Button Sizes under that.

Sorry about that. I use this add-on; Classic Theme Restorer (Customize Australis) {web link} Restore squared tabs, appmenu, add-ons bar, small button view and more on Australis UI (Windows/MacOSX/Linux + Fx 29+).

This will restore many of the things the last upgrades took away.

You can look at this extension to adjust the font size in the user interface.

You can set a global zoom via the Options/Preferences of the extension (about:addons or the Tools menu) that modifies layout.css.devPixelsPerPx. Modifying layout.css.devPixelsPerPx affects user interface and web pages (global zoom). Use an extension to correct the appearance of web pages if necessary.
