2023-05-19	MNK	Omg this an absolute LIFE SAVER. I'm currently trying to make edits to a site I'm making for someone and realized from feedback that we were seeing things differently (I have a 2560x1410 curved monitor. They have a 1920x1090 laptop. Does not compute). Tried to find an easy extension that would change my windows so I could view a window similar to how they were seeing it without having to change my display settings every time, mess with the window sizes to get that /just right/ dimension, or download unnecessary software when I only want my firefox windows to be changed. This extension not only allows me to input my desired width and height, but also name it and create shortcut keys. Love love love. As the creator has said multiple times in the other reviews, please make sure you understand what purpose this extension does before dismissing it as not working. Maybe it doesn't work for you because that's not the purpose it's trying to serve -- it just so happened to serve me and my idiotic thinking that everyone obviously is looking at a window in the same dimensions I am. Edit: Cool to see it's still being updated despite last review being 2 years ago. Haven't come across any bugs yet but nice to see it's still being overseen.

2020-12-15	Mardus	The extension shortucts interfere with Windows special character alt codes, such as when I want to type Alt+0149 for a bullet, the window resizes to one of the user-defined sizes as soon as I press 1 after 0 when holding the Alt key down. I cannot change this in Firefox versions earlier than Firefox 66, as these older versions do not have an extensions shortcut manager. I recommend making Shift+Alt+[number] the default instead of Alt+[number] in future versions of WindowSizer.
