Where Does OneTab Store Saved Tabs?
OneTab keeps saved tab lists in per-profile browser extension storage only, with manual export as backup.
Last updated
OneTab stores tab lists in extension storage inside the profile that saved them. No account exists and nothing syncs. The export produces a plain list of URLs.
That local-only design makes OneTab fast and private, with one sharp edge. Profile wipes erase years of saved tabs silently. Treat the export file as the actual archive and refresh it monthly.
Where OneTab stores this, by platform
%LocalAppData%\Google\Chrome\User Data\Default\Extensions (per profile)
Tab lists per profile with no cloud. Export URLs regularly. Import restores groups as links on the new profile. Profile loss without export is final.
~/Library/Application Support/Google/Chrome/Default/Extensions (per profile)
Same local-only model on Mac. Firefox builds keep it under ~/Library/Application Support/Firefox/Profiles. Duplicates and named groups survive export intact.
Frequently asked questions
How do I move OneTab lists to a new browser?
Use the export in the OneTab page to save URLs, then import on the new profile. Tab groups travel as plain links. There is no account or cloud to pull from.
Does OneTab sync across devices?
No. OneTab stores everything locally in that profile. Losing the profile without an export loses the lists. Export regularly if tabs are your task manager.
