Stack Overflow Indentation++ di Nathan

An Add-on that enables rich IDE-like tabbing and tab-shifting when editing questions/answers in Stack Overflow and Meta Stack Overflow.

It uses spaces (not tab characters) when you tab, and defaults to 4 spaces. It also adds a pretty gradient border to the text area.

Click on the extension in your toolbar to open up the settings, where you can change the spaces-per-tab, disable the border gradient, and disable the whole extension temporarily if you'd like.
