Bookmark & URL Utilities
Look up where popular tab managers store data and what to export before you remove or replace one.
Runs entirely in your browser. Nothing leaves your device.
How it works
- Search for your tab manager or choose it from the list.
- Read where the extension stores sessions: local extension storage, IndexedDB, bookmarks, or cloud.
- Follow the export steps before uninstalling or testing a replacement.
- Use a matching converter when the site has one, or fall back to a standard bookmarks export.
Why tab manager storage matters before uninstalling
Chrome extensions can save data in several places. Some use extension-owned local storage or IndexedDB inside your Chrome profile. Some use your browser bookmarks. Others sync to a vendor account or to your own cloud storage. Those choices decide what survives when you remove the extension.
The risky case is local-only extension storage. Chrome normally removes that private storage when an extension is uninstalled, so saved sessions can vanish with the extension. A profile backup may help experts in some cases, but it is not a migration plan. The practical move is to export first, open the exported file, and only then uninstall.
This checker is intentionally static. It does not inspect your browser, read installed extensions, or upload anything. It gives you a tactical checklist for known tools and a generic rule of thumb when your extension is not listed: local extension storage is fragile, bookmarks and cloud accounts are more portable, and an export file beats hope.
Frequently Asked Questions
Why do extensions lose data on uninstall?
Chrome removes an extension's private storage area when the extension is removed. If a tab manager keeps its saved tabs only in the extension's own storage inside Chrome (technically called chrome.storage.local or IndexedDB) rather than bookmarks or a cloud account, uninstalling can delete the saved sessions too.
Is that local extension storage ever backed up?
Not in a way you should rely on for migration. Chrome profile backups may contain this data, but restoring it is fragile and extension-specific. A real export file, bookmarks file, or cloud account sync is safer.
How do I move data between extensions?
Export from the old extension first, preferably as JSON or bookmarks HTML. Convert that file into a standard format when needed, then import into the new extension or into browser bookmarks. Never uninstall the old extension until you have opened and inspected the export.
Is this list current?
It is a static lookup with a last-verified date on every entry. Extension vendors can change storage models and export menus, so treat this as a checklist and confirm the current export screen inside your installed extension before uninstalling.
