This Chrome extension allows users with too many tabs open to hit the One Tab button and collapse all tabs into a single spot. This allows users to visit relevant tabs when necessary while having them all listed in a single tab. By doing this, you can save up to 95% of your memory because of the reduced number of tabs. Still, you’ll have any previously opened tab at your fingertips. Best of all, the One Tab extension is free of charge and perfectly secure. One Tab Website [Official Site]
