TabsafeBest OneTab alternative: free, and for Firefox
Updated
For Firefox today, Tab Session Manager is the free OneTab alternative you can install. Session Buddy is the mature choice on Chrome, and Workona suits project work. Tabsafe adds snapshots and backup files kept outside the browser, runs on Edge now and is in review for Firefox.
Why people leave OneTab
OneTab is free, simple and widely used. People leave for three reasons: they want a backup that does not live only in the browser, they want automatic saving instead of a button, or they want history they can search. Some Firefox reviewers also report losing lists (see our recovery guide); those are individual reports, not tests.
