To open new tab as First Tab doesn't seem to work, it opens as Last Tab, same behaviour as open as Last Tab. Otherwise most things else seem to work great! I initially wanted the open as First Tab, but will try "open to the Left Side of Active" for a while now, think it will be perfect actually! Firefox version: 76.0.1 (64-bit)

Awesome plugin, very needed! Missed this a long time.

I use these preferences:
New Tab Open at: Last Tab (default)
After Close, Change to: Last Active Tab

This is perfect because:
1) Ctrl+T and the PLUS SIGN button do the same thing: create a new tab at the end of the tab bar.
2) After closing a tab, the last active tab becomes active.

Enhancement request: make the preferences sync using Firefox Sync.

I recommend another extension that complements this extension: "New Tab Beside": it allows Ctrl+1 to open a new tab next to current tab.

Ja das ist ja super, vielen Dank. Sehr hilfreich!

So basic! I like it that this makes it easy for me to change how I want my tabs to behave without tweaking about:config. Install this plus Tab Session Manager and Undo Close Tab if you're missing Tab Mix Plus.

Much needed functionality. Shocked that this isn't a standard option in Firefox.

Danke!
