I am trying to use the tree style tree expansion for Firefox. When I install the tab bar appears at left side as it should, BUT the tab bar appears at the top too. I understand it has to do with the userChrome.css: Questions: 1. The css file is supposed to be created in this folder: C:\Users\jssch\AppData\Roaming\Mozilla\Firefox\Profiles\ 6p6hqx7v.App1d96b2329ff34563bd901f480a66632f\storage\permanent\chrome I that the correct location customized for my pc. 2. Could you supply the correct code for the css file. I am assuming I can use Notepad++ to create the file.

Thank you for your assistance. My email is jsschwab2002@gmail.com

The \storage\permanent\chrome is used for local storage (indexedDB).

The chrome folder should be created in the main profile folder. Primary location used for the main profile that keeps your personal data (Root Directory on about:profiles).

  • ~/Library/Application Support/Firefox/Profiles/<profile>

You can use the button in "Help -> More Troubleshooting Information" (about:support) to go to the current Firefox profile folder or use the about:profiles page (Root directory).


More info about userChrome.css/userContent.css in case you are not familiar:

You need to set this pref to true in about:config to enable userChrome.css and userContent.css in Firefox 69+.
