Adjust Firefox Windndow Size

more options

Hi.. since I update to windows 10, I can't adjust the size of Firefox window, because the arrows don't appear.. I've unisntall the browser and install it again, but there's no way. The only moment when I can adjust it is if I click F11 go to full window, when I back to normal size again.. there are a few seconds when the arrows appears.

Thanks in advance.

Hi there...

Sometime I think when you Lock a Browser in screen mode it will be okay.


 1.  Web Developer submenu ==> Scratchpad

(or try Shift+F4 to open Scratchpad)

  2. In the Scratchpad window type window your screen width to fix size what you want.
  3. Press Ctrl+R or open the Execute menu and choose Run.
