It worked for a long time and it was great. But no longer works for me. I'm using Windows 10, latest update on Chrome and I do work at a school behind a firewall.

only works when chrome doesn't update. I need my stuff to open in one tab at work and every time there is a update it does not work.

An extension that does what it claims to do. Excellent!

Recently, more and more popups have been infiltrating. Might have something to do with manifest v3. What a shame.

Finally, one that works well! +1 :)

Melhor extensão para o Chrome do gênero. É a única que coloca a pop-up numa aba imediatamente ao lado direito da aba que chamou a pop-up. Outras extensões colocam lá na última aba. Enfim, um trabalho primoroso que merece nosso like e recomendação.

Doesn't always work, e.g. if a tab is already open because you clicked a link and then clicking the same link that would open the same tab with the same "_target", the popup opens as a window, the old tab gets closed correctly but the new popup should also be moved to my active window.

Warning: This makes all "restore session" tabs and tabs from other devices etc all open in one window too! Also, it is buggy when opening a mobile phone session on PC, it opens one tab in one window and the rest in another. I currently have a single window with hundreds of tabs which I'll have to sort out manually due to this extension. Because of these issues, I unfortunately cannot use this extension.
