Despite the reviews claiming it doesn't work now, it does work on my side.

Doesn't work anymore. It's now useless. With 10 tabs open on my right, it can appear anywhere in there and not on my immediate right.

It looks like developer gave up on it since it's been about a year since it's last update.

Doesn't work inside tab groups. :(

Doesn't work when I open link in new tab

Doesn't work at all anymore for years now, so I finally give up.

New tabs are almost never opened right next to the current tab, but ANYWHERE to the right, which means you have to search the new tab AND the old one after stwitching tabs.

That's basically standard FF behavious, so I obviously don't need an addon for that.

Пользуюсь этим расширением много лет, работает отлично. Большая благодарность автору!

Does not work for me. Have only 1 tab open. I have two sites on bookmarks toolbar, which I have set to always show. As soon as I clicked to open one of the two on the bookmarks T.B., it opens on top of active tab. It did not open to the right of the active tab. I also went to about:config, but it was set for 'true.' Perhaps I overlooked something?

Does what it says it will do, thank you Developer, my tabs now open directly to the right thanks to you A++

Incredible! Instantly installed and instantly worked. I have NFI who in the hell at Firefox HQ thought I would like to swipe 50 tabs to the right to access a tab I'd only just opened, but this plug-in is the fix I have been wanting. Only just googled the problem, so my apologies if your brilliant solution has been aroumd awhile. All best wishes from Bonnie Scotland!
