When I middle-click to open a link in Chrome, I like the tab to show up right next to the tab I’m on, not all the way at the end of the row of tabs. The Tab Position Customizer extension worked great, then it disappeared from the Chrome Web Store. For the past few months I’ve been using the development version of the extension that I salvaged. But it’s gotten annoying to have a pop up window asking if I’m sure I want to use the development extension every time I start Chrome.
So I published it in the Chrome web store for all to use. I only use the open tab on the right option. I have no idea if the rest of the options work as advertised. If you want to make any changes, the code is on on Github.
