Popup To Tab

Hate it when websites open their portals in a popup window because they're so special and need to hide the back and forward buttons?

With this add-on you can now turn a popup window into a tab and merge it into your main browser window. That way everything fits neatly into your tabs and you don't have windows flying everywhere.

The next time you have a popup open, simply click on the toast notification that shows up to merge the popup window into the main browser window.

You can also click on the extension icon in the toolbar on the main browser window too.

Bonus:

I am pleased to report that this extension requests no discernible permissions, so you may use it in complete confidence.
