This is the best addon for sorting tabs. You're able to sort them from the tab bar itself rather than through a popup on the toolbar.
There are also many more sorting options than in other competitor's addons.

This extension is simple to use and covers all major needs at sorting tabs.

Many times it happens that you have a series of tabs opened in the reverse order and you need to reorder them in the correct order. As the number of tabs increases this can be a real pain in the ass.
A typical example is when you try to load in a new installation all the synchronised tabs from an older installation (when you move to a new computer or you have to reinstall Windows). If you had 400 tabs in you old browser, those 400 tabs will open in the reverse order!

So it would be great to have an option in the tab context menu to "reverse the order of the tabs to the right".
Why to the right of the current one? because a typical situation is you already have several tabs opened and then you open several tabs at once and they get opened in the reverse order. So you want to reorder only the newly opened tabs and not all tabs and those tabs will be the rightmost tabs so you can execute the command on the leftmost tab of the group and Click-Tab-Sort will understand what tabs you want to sort.
