Some people may find the fact that Firefox opens a new tab on the far right of your tab toolbar a blessing and some might find it a curse. It really has to do with how many tabs you are look at, in one single browser. For those who are cursed today, I have your solution. The Tabs Open Relative extension changes how new tabs open up, which means no more tab surfing for you.
Once installed, the Tabs Open Relative add-on for Firefox will make all new tabs open to the right of the current tab, rather than the far right of the tab bar. Of course, this only applies when you are clicking links on a page. In the case where several new tabs are opened in a row without switching tabs, each subsequent tab will be opened to the right of the previous one, so as to keep them in order.
So if this sounds like the solution to the tab navigating curse you’ve been living under, be sure to pick up this extension via the Firefox Add-ons site. It is an easy way to fix this tabbed browser nuisance.
