Portage par pvrz

Portage is a universal browser data migration tool. Export your browser's data to a single portable file, then import it into any other browser running Portage — whether you're switching browsers, moving to a new machine, or keeping two browsers in sync.

What you can export

• Bookmarks (full tree, folders preserved)
• History (with timestamps)
• Cookies (so logins carry over)
• Open tabs (reopened on import)
• Sessions and reading list
• Installed add-ons (as a reinstall checklist)

How it works

Pick what you want to export, optionally encrypt it with a passphrase, and download a single .portage.json file. On the destination browser, install Portage, drop in the file, and choose what to restore.

Privacy

Portage runs entirely on your device. It does not send any data over the network, has no analytics, no telemetry, and no remote endpoints. The export file is saved to your local downloads folder — what you do with it after that is up to you. Optional AES-256-GCM encryption is available if you plan to move the file across an untrusted channel.

Why the permissions

• Bookmarks, History, Cookies, Tabs, Sessions — to read the data you're exporting, and to write it back on import
• Management — to list installed add-ons for the reinstall checklist
• Access your data for all websites — required by the cookies API to read site cookies during export
