About OneTab
OneTab is the simplest tab saver in our picks, and the only one with a Safari option. Click its icon and every open tab in the window becomes an entry in a single list. The tabs close, and you can restore them one by one or all at once. The store listing claims this cuts memory use by up to 95 percent, because the pages are no longer loaded. That is the developer's figure and we did not test it.
The developer is OneTab Ltd, a UK company named on the Chrome listing, and the extension is free. Chrome shows about 2 million users and Firefox about 161,000. Safari users get a free OneTab app on the Mac App Store, version 1.87, last updated in November 2024.
The listing says tab URLs are never sent to the developers or anyone else, except through the optional share as a web page feature, which uploads a list. Chrome's store label says no data is collected. The code is closed, so none of this can be checked against source. OneTab suits occasional tidying. For automatic sessions or workspaces, look at Tab Session Manager or Workona.
