This extension does not work.

Doesn't work for Deliveroo links.

(Somehow Deliveroo links for restaurants override the usual open link in new tab behavior, though I can still right-click on the link and select "Open Link in New Tab" to force it to open in new tab. This was why I was looking for some add-on such as this, but unfortunately this add-on did not work.)

Also, this add-on doesn't work for bookmarks.

browser.tabs.insertAfterCurrent is now workings correctly!

It doesn't seem to work.

Works exactly as it should after setting the correct option. Must go to FF's 'Manage Your Extensions' page > Click the three dots [...] next to this addon > Select 'Options' (or the 'Options' tab on the 'Manage page) and select "Open a link to a different site on a tab" or "Open all links with tabs" depending on your preferences.

Simply put, it does not work. At all. No matter what you do, or how you do it, it will not work.

It doesn't seem to work at all

Works most of the time, still get a javascipt(0) error very often though

Javaで遷移しない
javascript:void(0);

Doesn't work with all links but works good enough.

Does what it says on the box. Naysayers probably failed to set the options CORRECTLY
