The way it should be. Thanks!

Works for me. Thanks.

Thank you, Dietrich. Been using this indispensable extension for years! However, I now have an ongoing problem where I'm having to reinstall it each time I restart FF, because opening a new tab will always go to the end of my tabs if I don't. Currently using Always Right Version 10.1.6.3 on Firefox 57.04. Any solution to this problem?

59.0.2 (32-bit)
After some time working correctly, just recently I find tabs opening at end of line again.

~~~~~~~~~~~~~~~~~~~~
It's absurd this isn't the default.

Using Nightly [now 58.0a1 (2017-10-07) (32-bit)] sometimes ctrl_T goes to end-of-tabs instead of the next slot,

Just now, I did ctrl_T from the frst tab, it went to th end of the line; I moved it back manually.
Next I tried it on a mid-tab: fine, it went to next slot.
Tried again on first tab, this time it worked properly.

I suspect it's a photon glitch, some module not loading in time without being checked. Is there a way to ensure it works always?

Additionally, when I ctr_T on the first tab in the visible row, it not only creates a tab, but shifts focus to it (which is an assumption too far), and moves the current tab leftwards out of view. So I then have to move left again to see where I was.

The search function also changes focus to the search page rather than opening it in background. So, if I need to search for several items on a page, I have to go back & forth each time.Could be another piece of slack thinking by mozilla.

pls make affect on open a link by middle click

I figure out in order to make it work, browser.tabs.insertRelatedAfterCurrent have to set to false.

Exactly what I need
I never understood why this choice was not available in Firefox settings.
Thanks for your job!

Thanks Dietrich, the addon seemingly works great. Could you make something similar; an extension which does so when tabs are closed, the focus is switched to the last active tab?

Have been using this add-on for a few years now. Super useful and it annoys me that the default action in Firefox when opening a new tab is to put that tab at the end. I open many tabs at once so it gets very crowded fast in the tab bar. This addon helps to not lose the new opened tab.
Thanks!

Installed another similar addon, doesn't work as smoothly as this one.

A very useful addon which I use a lot. Unfortunately since 2.0.0 icm FF 53.0.2 64bit and Windows 10 it isn't working anymore :(

I miss it very much..
