I Hate Tabs - SDI for Firefoxby jscher2000

If you use a version of Firefox that has a Windows menu, you may prefer not to have multiple tabs in the same window. Give this extension a try.

If you ever used the Chrome extension "New Tab, New Window" or "Tab-less", this one uses the same APIs (detect new tab => create new window for that tab).

Note: This extension does not hide the tab bar, nor menu commands related to tabs. If you want to hide those, you could consider using custom style rules in a userChrome.css file. I posted an example here: https://support.mozilla.org/questions/1237154#answer-1164247


BUG ALERT: The Customize tab does not work when moved to a new window. In order to use Customize, you'll need to temporarily disable this extension on the Add-ons page, Extensions panel. After you finish customizing, you can re-enable it.
