I use a lot of extensions, but am pretty sure this is the one that had this feature: When resizing the browser window by pulling it larger or smaller, the window size and viewport size would show up in the lower right corner of the website. It was awesome. Now, on the latest update of this app, it's gone away :-(
I know I can get a similar thing by doing 'inspect' in Chrome, but that's tedious.
Is it just hiding somewhere or did you really get rid of it?
