Move your OneTab lists into another tab manager
Switching tab managers is scary because the lists are years of saved links. The safe way is to export first, import second, and only then stop using the old one.
Import OneTab lists
In OneTab, open the page for importing and exporting URLs and copy your lists as text. Keep a copy of that text in a file somewhere, so the old data is safe whatever happens next.
Open Plainware Tabs’s vault and choose Import.
Paste the text, or choose the file. Plainware Tabs recognises OneTab’s format, including titles that contain a vertical bar.
Look at the result. It tells you how many lists and links were imported, how many were already in your vault, and how many it skipped and why.
Open a few of the imported lists to check them. Imported lists are kept until you delete them, so history clean-up never removes them.
Other things it can import
- Session Buddy backups, in both the newer and older formats.
- Bookmark files exported from Chrome or another browser, and a live bookmark folder (Chrome asks for bookmarks access at that moment).
- Plain lists of links, one per line.
- Plainware Tabs backups, encrypted ones included.
Why this is safe
- Imports only add. They never delete or overwrite what’s already in your vault.
- Importing the same file twice reports “already in your vault” instead of making duplicates.
- Nothing is skipped silently. Skipped entries are counted and shown.
- It works on your computer. Your lists aren’t uploaded.
Limits
Formats can differ between versions, so check a sample of lists after importing. Restoring a list reopens its links as normal tabs. It can’t recover pages that no longer exist, and Pro’s dead-link check is how you find those.
