Some of the tweaks require modification to your userChrome.css and/or userContent.css files located in the chrome folder within your profile folder.
Please note:
- Changes made to the userChrome.css and/or userContent.css files can NOT be undone once saved. Therefore before making any changes to the userChrome.css file make a back-up copy first.
- IMPORTANT: Close Firefox before saving changes made to your userChrome.css and/or userContent.css files. Firefox writes to these files upon exit and will override any changes you made if not closed first.
- WARNING!!! DO NOT REMOVE the line which starts with: @namespace in the userChrome.css file
- This file should only be edited with a text-editor such as Notepad or Notepad++. It is NOT recommended using MS Word or similar Word Processor applications. For best results we recommend using the ChromeEdit Plus Extension. The extension will automatically locate your userChrome.css and userContent.css files and open them in an external editor. You will be able to modify these files, save your changes and restart Firefox.
