Version 0.5 adds a new toolbar button to set a default position and size for new resizable windows if you don't like where Firefox is placing them. Too many buttons? To remove an add-on button, either:

OMFG I can finally control the size of new Firefox windows!! I no longer have to worry about smaller sized popups (or going full screen) overwriting the default new window dimensions. Thank you so much!

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Change New Maximized Window to Resizable does not require any sensitive permissions.

Risk impact analysis details

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Change New Maximized Window to Resizable has earned a fairly good reputation and likely can be trusted.
