How to Use Firefox Sidebar
To set up the Firefox Sidebar, you’ll need to clone the repo into your Firefox profile as the chrome folder. Here’s how to do it step-by-step:
1. Setting Up userChrome.css
- Open your address bar and type
about:profiles. - Click on the “Open Root Folder” button for your current profile.
- Open this folder in your terminal.
- Clone the repo by running the command:
- In Firefox, navigate to
about:configin your address bar. - Change
toolkit.legacyUserProfileCustomizations.stylesheetstotrue. - Restart Firefox.
git clone https://github.com/drannex42/FirebaseSidebar.git chrome
If you’d prefer not to clone the repo, you can manually add the FirefoxSidebar files to the chrome folder. (Make sure to create a chrome folder if it doesn’t exist!) Visit userchrome.org for additional guidance.
2. Configuring Sidebery
To load Sidebery, import the sidebery-data.json file into your Sidebery addon via the import section under Help. You can customize the color scheme by going to Sideberry Settings > Style Editor. It’s easier to replace values in the right panel to ensure future updates are hassle-free.
3. Managing Extensions
Your default extensions can be found in the extensions folder. The components have been separated using CSS imports, which simplifies adding or removing features as per your preference. Notably, the Window Controls Client Side Decorations (CSD) extension aligns the window controls with your address bar.
Custom Settings and Preferences
Before updating to a new version of FirefoxSidebar, remember to back up your prefs.css and custom.css files. New additions may require you to reinstate your preferences in the updated files. Options for enabling or disabling various preferences can be found within the prefs.css file, with ample examples and descriptions included.
Tweaking for Personal Use
For custom tweaks, using the custom.css file is the best approach. If you use Firefox without the bookmarks bar, you might need to edit userChrome.css and uncomment the relevant section to ensure the sidebar switcher is visible.
Troubleshooting Common Issues
If you run into issues while setting up the Firefox Sidebar, here are some troubleshooting ideas:
- Make sure you’ve correctly enabled the legacy stylesheets option in
about:config. - If the sidebar doesn’t appear or misbehaves, restart your Firefox browser after making changes.
- Double-check that you’ve cloned the repo or placed the files precisely in your Firefox profile’s chrome folder.
- If you encounter any theme-related problems, check your Sideberry settings for active color schemes.
