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.

It works fine... for a while. I have 3 windows where it's supposed to be without toolbars and every once in a while after rebooting, one of those windows loses its configuration and i have to launch that windows again without a toolbar. Gets annoying after a while.

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

It's a pity that it doesn't just hide all the bars in a window, it just opens a new window for a given tab, but it does the job well.

There's still A BAR across thew top. I managed to hack it tho :(

Exactly what I've been looking for!

Using Firefox 96.0.3 and it does not work for whatever reason. Bummer.

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

Please, add the option to hide the title. It appears even when the option is deactivated, and be able to close it with Ctrl+Q or something.

It does exactly what I wanted! Although, I can't use it because it always gives focus of the window it creates and it's on top of all the other Firefox windows.

It would be 5 stars if I can minimize it, or hide it or change focus to the "main" Firefox window.

Nice tool to focus on contents
