Good concept, have used in the past but removed for now. As others have noted, it opens the New Tab settings page rather than the selected New Tab. Also, removing the add-on didn't work.

Update to reply to developer response: "New Tabe Override still works." I'm giving you feedback that it doesn't, I could give you more information (Firefox on Dell laptop running Win 10 etc.) but a blanket response like that is odd. Why would I bother leaving this comment if I'd not had an issue?
To clarify "removing the add-on didn't work" in response to your answer - I just clicked on the remove button and the removal path (menus etc.) appeared but the add on was still present on Firefox. I did this a couple of times before it eventually went. Other add-ons have been successfully removed first time. I mentioned this because it seemed like useful feedback, I'm not smart enough to either develop apps or know whether it's possible for them to have an issue that can interfere with the removal process, although I have worked alongside software testers for enough years to believe that all kinds of unexpected behaviours can sometimes occur with software, so any feedback is usually useful in case the issue is a defect that impacts others, rather than just a temporary glitch or problem with the machine or browser.
It certainly could be something broken on my system, I'll be on the look out for any other apps not removing properly, thanks for the tip.

Does not load external css when used with local file due to firefox security limitations

I've been using this extension for a while and haven't had any problems. In fact, I consider it as essential. Very simple to use.

Does the job

absolut unverzichtbar bei jeder Neuinstallation!

espero que todo sea bien

Great APP but...

A couple of months ago after a Firefox update (IDK around the 100 update or so?) if I want to reopen closed tabs I cannot do so if I first open a new tab.

All that will 'reopen' will be new tabs.
It will reopen previously closed tabs otherwise, so it isn't a problem if as long as one remembers the bug.

Are you aware of this? - To developer.

Appreciate your time & indeed your App, TY.

Extension works perfectly except for keeping focus on the URL bar when the new tab is opened. I specifically wanted this addon for a website that would already have user input upon loading, and when it focuses on the URL bar I can't type in said user input.
