Shift Between Preset Window Sizes in Firefox with ResizeIT

Do you need multiple different “exact-size” windows for web-design work or other activities throughout your workday? Then see how easy it is to switch between sizes with the ResizeIT extension for Firefox.

Before

Here is our pre-extension test browser set against a 1280 x 1024 pixel sized background. Notice the position and size of the browser versus the wallpaper…

Options

As soon as you have installed the extension and restarted Firefox it is recommended to immediately access the “Options”. These are the default settings for the four window sizes that you can switch between.

For our tests we selected for “Position” in relation to all non full-screen sizes and made a slight change to the “Alt + 2” listing so that it was close in size (and proportional) to our browser’s size in the screenshot above.

Once you have made any desired changes click “OK” to save your new settings.

ResizeIT in Action

Here are the results of our settings. The “Alt + 1” keyboard shortcut setting of 300 x 300 pixels…

The “Alt + 2” keyboard shortcut setting with our altered browser window size of 869 x 651 pixels…

The “Alt + 3” keyboard shortcut setting of 1024 x 768 pixels…

And finally the “Alt + 4” keyboard shortcut setting for full-screen.

Now if you are wondering if you can enter in unique and/or unusual custom sizes the answer is yes. Just for fun we altered only the “height setting” for the “Alt + 1” keyboard shortcut. Enter in the appropriate pixel size(s) and click “OK” to save your settings.

Here is the result of the size modification. Custom sizing makes this an extremely useful extension…

    I was looking forward to using this but neither this one, nor Smart Resize work for Linux. Arggghhhhh!!!

    For our tests we selected for “Position” in relation to all non full-screen sizes

    …because you also don’t know how to make it save different screen positions for the different sizes, right?

    No pattern seems to be able to save one window position without rewriting the other two. Your how-to article doesn’t address this problem. Any advice?

    @Adam – It bases the positioning for all the non-full screen sizes on where you have Firefox at the moment…

    When you select for “Position” in the options that only tells the extension to hold it in the current position and does not store multiple “saved positions” for all the non-full screen sizes.
