When your Chrome experience any problems (after performing a backup) can try to create a new profile to see if the problem can be resolved. Respectively, to deal with Windows, Mac and Linux, Google Chrome's default configuration file storage path is as follows:
- Windows 7 至 Windows 10：C:\Users\<username>\AppData\Local\Google\Chrome\User Data\Default
- Mac OS X El Capitan：Users/<username>/Library/Application Support/Google/Chrome/Default
If you need to edit other profiles, you can easily view the specific path. Each time when switching users (profiles), are to open the configuration file with a new Chrome window, then executed in the address bar :
chrome: // version, you can view the specific configuration file path.
