Firefox Open New Tab Next to Current Tab
If you have a lot of tabs open, it’s very irritating when you open a new tab with Ctrl + T only to have it be opened at the very end of your tabs. For a long time the way I used to work around this was to duplicate the tab that I was in and then change the URL .
Turns out there is a way to change this default behaviour in Firefox. Open about:config and change broser.tabs.insertAfterCurrent to true. This setting seems to also override browser.tabs.insertRelatedAfterCurrent, so if you have the browser.tabs.insertAfterCurrent set to true, this will also be true irrespective of it’s value.
