Recently my chrome glitched and tampermonkey just stopped working. I uninstalled and then reinstalled extension (with hope that scripts stay in place), but my scripts got deleted. Luckily I have a backup of profile directory. So how I can restore them?


Not clean backup but something. Go to:

%LocalAppData%\Google\Chrome\User Data\Default\Local Extension Settings\dhdgffkkebhmkfjojejmpbldmpobfkfo\

And find file 000003.log or similar. This file stores whole history of changes of all userscripts. Just search for website name, that uses your script.

    I have a very similar issue. However, 000003.log appears to be a binary file. How can its script history data be read in plain text? – MJH Nov 27 '16 at 4:38

    @MJH I just used Windows build-in Notepad. – hlcs Nov 27 '16 at 6:39
  • Strange. When opened in Sublime Text 3 it appears to be binary data, but when opened in Notepad it appears to be text (rather difficult to read, though). Thanks. – MJH Nov 27 '16 at 6:50
  • This didn't work, the file is empty after the new installation :( – Jay Feb 2 '19 at 16:04
  • Agreed, this will also not open on my machine. But it does seem to be the correct file. I will work harder :D – Jamie Hutber May 26 '19 at 21:51

You can use this python script to extract your scripts from the profile backup folder:

  • Please read the question again carefully. Your answer does not answer the original question. OP is using Windows not Linux or OS X – DavidPostill Nov 28 '16 at 12:57

    @DavidPostill And what is the problem with installing Python for Windows? Another option is to boot a Linux Live CD. – derjanb Nov 29 '16 at 19:52
