My computer crashed and I reinstall it over a new disk with chrome and the OneTab extension. However, I can't find where OneTab is storing my data under my former disk. I used this answer Where does Chrome store extensions? to go to the folder but there is no file dated close to the computer crash (and I used it on a daily basis).

    if you are here, but you were looking for Firefox information. There is an [official page for it](http://www.one-tab.com/firefoxRestore). – aloisdg Sep 14 '16 at 13:11
  • I've moved to a different tool because Firefox has converted the extension data storage to a db file.. https://superuser.com/a/1714380/388883 – alchemy Apr 04 '22 at 03:39

I found it after using onetab and than searching for all files changed on that minute... So to restore one-tab from one computer to another you need to do this:

  • use one-tabe
  • search for C:\Users\XXXX\AppData\Local\Google\Chrome\User Data\Default\Local Storage
  • find these 2 files:
    • chrome-extension_chphlpgkkbolifaimnlloiipkdnihall_0.localstorage-journal
    • chrome-extension_chphlpgkkbolifaimnlloiipkdnihall_0.localstorage
  • kill chrome so you will be able to back up 2 files in the directory
  • change the recent changed files extantion
  • copy the old 2 files from your backup to the folder
  • restart chrome

    I didn't understand the "change the recent changed files extantion" point, could you explain please? Which files do we need to change and what extension should we use? – user3641702 Apr 20 '17 at 09:17
  • just copy and replace, take a look at Fotis Dimanidis's comment if you have multiple profiles – Gaston May 03 '17 at 21:18
  • There must be some other possible location for OneTab to store its data. It's working properly on my Vivaldi browser, but among the four `chrome-extension_*.localstorage` files I can find on my entire disk, none of them seem to contain its data. – Daniel Saner Nov 27 '17 at 09:37
  • When reopening Chrome, it's possible to press the Undo closed tab keyboard shortcut `CMD + shift + t` keys on a Mac. This often brings back the last Chrome session. Sometimes you'll see a blank OneTab window as well as the recovered window. – Nik K Apr 01 '20 at 16:27

    It appears the extension files are in a new location as of 2021 June: c:\users\xxxxx\appdata\local\google\chrome\user data\default\local extension settings. You should copy the entire folder chphlpgkkbolifaimnlloiipkdnihall to the same location on the new computer. – eafpres Jun 12 '21 at 20:02

Restore OneTab on Mac

Bailed me out when after using Cocktail (a system cleaning utility) to clear out logs/caches, etc.

The two files mentioned above for PC above are the same for Mac.

The same file path is used on the Mac:

/Users/your-user-name/Library/Application Support/Google/Chrome/Default/Local Storage

  • Quit Chrome.
  • Select the two files in the finder.
  • Enter a Time Machine back up; it will automatically locate them,
  • Choose the latest date before you wiped out OneTab,
  • Do a Restore, copy over the old ones.

That's it. Back to normal.

    In a multi-user Chrome setup the files lie in: /Users/your-user-name/Library/Application Support/Google/Chrome/Profile 1/Local Storage – Foti Dim Nov 19 '15 at 08:57
  • Which "the two files" are you referring to? – Alejandro García Iglesias Oct 09 '17 at 23:19
  • The instruction totally saved my day! I think these should put into the official FAQ page of OneTab extension. – AJ H Feb 07 '18 at 08:46
  • @AlejandroIglesias Could be any two files in `/Users/your-user-name/Library/Application Support/Google/Chrome/Default/Local Storage`. It will helps you to locate to the path in Time Machine. – AJ H Feb 07 '18 at 08:49
  • i lost all my one tab after upgrading macos to 10.14.5, then i restore /Users/your-user-name/Library/Application Support/Google/Chrome/Default/Local Storage/leveldb (remember backup first) from timemachine, and the miss tabs are back. – 0xTang May 15 '19 at 03:40
  • I got the leveldb folder and contents copied, is there a way to read it in a human language? My company have blocked all chrome extensions so no failure has occurred but unclear on to get the last good copy – shicky Aug 11 '21 at 12:38
