Do exactly what it say. A good feature could be to be able to open a windows without toolbar with a shortcut of firefox

Does what it claims, with a Tool menu option, context menu option, or toolbar icon. I find it really useful on my 55" monitor to have sites I want to monitor open with the maximum space for the site, tucked off the one or other side of my main work area. Highly recommended.

does what it says it should. Really helpful on wide screen computers when doing horizontal type work, which is to say, most work you'd do on a computer! word processing being the top contender.

Windows created by this extension are ignored by Windows' window snapping feature. Any way around this?
Edit: Win+arrow snapping shortcuts work.

Exactly what I've been looking for!

It does a very simple thing, and that thing is extremely usefull in a lot of contexts.

This plugin is perfect! Simple and easy to use.

Woah! It just does what it does!

super useful for screenshoting screen

I can't emphasize enough how useful this feature is for people who easily get distracted and who want to still maintain full control and customization of Firefox with side bar, huge toolbar and favorite bar with lots of items. This is effectively a distraction-free mode, which every browser should include.

More people should know about this

Nice tool to focus on contents

Nice, but could you please add the option to HIDE titlebar ( like #navigator-toolbox { visibility: collapse !important;}), but for the window without toolbar?
And please add this command to Bookmarks context menu also.

Amazing shit.
