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.

This is something what i missed from chromium. but can you make it support maximize window modes? And also, where is github page for this one? perhaps issue tab is better for these kind of questions.

Love the app. I would love to see this have a feature where I could add other add ons. I have these two add-on 'Always on top' & 'Windowed Fullscreen' That would make this the perfect way to browse.

It is very useful addon. Thanks for your efforts. I am using it on debian linux, Firefox 60.4.0esr. After the latest update it won't work anymore. Nothing happens when i click at toolbar icon or select page context menu item.

16-01-2018: Still not working on debian linux, Firefox 60.4.0esr. How can i privide additional info to help you? May be i can look something in code inspector?
Get back to Version 1.0.2, working pretty fine.

Works great with my window manager, saves me a lot of space when having multiple windows open.

Works perfectly, thank you.
