Side Tabs is an add-on for Firefox that changes the position of tabs open in your browser from the top bar to the side. Unlike the traditional format (While tabs positioned at the top of the screen), with this extension they become vertical and displayed on left side of the application. Side Tabs stands out for proposing a different way of displaying the tabs open, however, it fails in a big point. Side Tabs hides the overlaid portion of your browser and thus your browser window becomes really small. But it gives you more usability if you work with many tabs at once as it makes it easier to access them frequently from the sidebar. Thus it’s effective to boost your speed. More to read.
During our test, the application worked perfectly and can be an good solution for those who usually have many tabs open at once in Firefox. The fact of placing them all on the side allows greater control and also facilitates the visualization of titles of the open pages. You can also be able to create a new tab simply by clicking on the + sign from the top of vertical list. Another useful feature is you can use CTRL + TAB shortcut to switch between tabs in Firefox so it will also allow to remove one of the great Firefox add-on, CTRL +TAB toggle for Firefox.
When you install Side Tabs, opened tabs menus goes to the left side of Firefox instantly. However, you can change the default position of the sidebar to right side from Firefox button> Add-ons > Options (From Side Tabs) and activate the Display tabs on the right and see the tabs to the right of the window.
