brilliant. all i need for my browser for "sticky" windows.

Perfect for Google Sheets and Docs to make them look more like real Windows apps.

Exactly what I was looking for! One click and I was done. Brilliant!

This addon has a huge potential! You should make that the windows automatically get miximized, pixel sizeing in the opitons not always do the work. Also, you should work on getting a full screen view, but without hidding the windows bar, so it looks really like a Web App. Hope you take this suggestion.

This worked littlebit better than others what makes the same here, so thank you :)

I wanted to pop out a music video playlist from youtube so I could have a small screen on my desktop. This add on allows me to to that. Thank you! :)

Does exactly what I needed, thanks

This add-on is perfect for running a web application in a separate browser window as if it were a native app (like a "PWA" for the desktop). On Linux, it's quite convenient to use this add-on with e.g. the Outlook web app instead of https://github.com/julian-alarcon/prospect-mail and the Microsoft Teams web app instead of the Linux client, which crashes a lot. With this add-on, there is no need to install an extra electron-based app that runs in its own little web browser (i.e. electron), when I can just run it in a separate window of my existing browser.

I was looking for something that worked like Chrome Apps for Firefox. This is even better! It works on any tab without configuration. One click and instant app window from any tab. Perfect!

OK. Resizable to any size!!! Wow! This is the absolute best, no comparison to those little window thingies that only get so big and that's it.

Great extension that I hope lasts forever. Would be awesome for Chrome also.

I would gladly pay a little for this if I had to.

Now for suggestions. Make it (easily) possible to revert to normal browser window, instead of just closing, and It'd be just perfect .

Now, where can I donate to the author?

only problem is the window wont dock like normal windows and you cant use the full screen button

I love that there's a light and dark version of the icon, it would be nice if it detected the background color automatically, but I don't know if it can be done.

Please add a keyboard shortcut and this will be a 5/5 extension!

This is what I was looking for, but if there could be a keyboard shortcut it would be perfect.

Popup works, but can't snap at screen edges like others do. Would be nice to add snappable windows.

I have looked and looked for an extension or a script of some kind that does this. It's amazing for multitasking when you can stay within the same browser, or when you just want that little extra screen space. Very, Very, Very well done.

I use this add-on (in pair with web-app) every day, but I don't understand why I can't maximize or minimize windows (on Ubuntu and Windows this options there aren't, but seems that on MacOs works as example picture shows) and why these popup windows remain constanlty over other ones no-popup.
I prefer that developer will integrate these features as soon as possible (or integrate infos in order to obtain the same effects on other platforms).

good add-on!
... but a 'always on top' function would be great if it were possible !!!
