How to completely uninstall webstorm on ubuntu [closed]
According to the WebStorm documentation, the config is stored in ~/.WebStorm9
So assuming you did not change the default location: from the command line run
rm -rf ~/.WebStorm9Update
For versions around the year 2020 you should go to the ~ and find .config and .cache folder and then delete your specific folder version inside JetBrains folder:
~/.config/JetBrains/<product><version>~/.cache/JetBrains/<product><version>
