Inside tab groups, the new tab doesn't open right next to the current tab but two tabs to the right.

Works as intended with some problems, especially in newer versions. Be careful since it can crash Firefox if you're using Wayland in Linux.

Still working great on Firefox 133, thank you!

It works, except for the fact that it jumps you to the end all the same. Fixing that would make this perfect. Much better than the default, though.

browser.tabs.insertAfterCurrent didn't work for me, but this works perfectly

Wonderful. This addon is still needed If you want to open your tabs in recent-to-last order if opening many of them at once ()

Addon developer not willing to continue development due to allegedly no cooperation of Mozilla. Addon superfluous with browser.tabs.insertAfterCurrent being in Firefox now, and Mozilla apparently not appreciating this addon-developer for his time.

browser.tabs.insertAfterCurrent does NOT work as I expected. If I middle-click to open, say, 3 links from a page, the tab order will look like this "(current) (1) (2) (3)". browser.tabs.insertAfterCurrent works only when using Ctrl+T or clicking the "New Tab" button.

But this extension works perfectly! If I middle-click to open 3 tabs after installing this extension, the final tab order looks like this: "(current) (3) (2) (1)" i.e. the last opened tab is closest to the current tab.

needs to override firefox "jumping" to the right most tab.

It's not immediately convenient for the tab to be added immediately to the right of the current tab if firefox does the disorienting thing of jumping all the way to the right of all 70 of my tabs anyway.

using browser.tabs.tabMinWidth in about:config to try help.
