'OneTab' is my favorite Chrome extension. I backup regularly OneTab data in Windows 7 following this link:


But today, I can't find OneTab data in that path.

Is anything updated in Chrome or OneTab? If so, Where is OneTab data?

Thank you.


On the Mac the location is now in a database file located in your users folder

~/Library/Application Support/Google/Chrome/Profile 1/Local Storage/leveldb/ files here...

Not sure if all the files here are dedicated to OneTab, but restoring the whole folder worked for me. You may need to check for other Profile folders, or perhaps the default instead of my "Profile 1" folder. A shortcut to the folder, open terminal and execute the command

open ~/Library/Application\ Support/Google/Chrome/Profile\ 1/Local\ Storage/leveldb/

Your OneTab data can be found at C:/Users/<Username>/AppData/Local/Google/Chrome/User Data/Default/Local Storage/leveldb. Just replace <Username> with your user's username.

I also created a Python script to automatically back up your OneTab data.


More information found in the link above.


This seems to be the latest place where the files are located:

C:\Users\yourname\AppData\Local\Google\Chrome\User Data\Default\Extensions\chphlpgkkbolifaimnlloiipkdnihall


Looks like the path has changed since then.

Now, the localstorage file resides in ~/Library/Application Support/Chromium/Default/Local Storage (on Mac, but it's easy to guess the equivalent on Windows


On (mint) linux, the path to the OneTab data folder appears to be:

/home/<user>/.config/chromium/Default/Local Extension Settings/chphlpgkkbolifaimnlloiipkdnihall


/home/<user>/.config/google-chrome/Default/Local Extension Settings/chphlpgkkbolifaimnlloiipkdnihall

Copying this folder from chromium to chrome (after chromium access to chrome sync API was recently disabled) adds all the titles and options associated with OneTab links.
