Gnome - Extensions - Install GNOME Shell extensions manually

Visit the GNOME Extensions website and download the extension with the latest version.

NOTE: Extensions can be downloaded and installed later, even without needing internet.

Steps

Extract the downloaded file.
Determine the the actual extension subdirectory name to create or use.
- Open the metadata.json file, and look for the value of uuid.
- IMPORTANT The name of the directory where the extension is to be installed must be the same as the value of uuid in the metadata.json file.
Create the directory where the extension is to be installed.
- This would be ~/.local/share/gnome-shell/extensions/xxxxxx directory; where xxxxxx is the uuid value determined above.
Copy the extracted extension files to ~/.local/share/gnome-shell/extensions/xxxxxx directory; where xxxxxx is the uuid value determined above.
Restart GNOME Shell. Press Alt+F2, and enter r and press ENTER to restart GNOME Shell.
Restart GNOME Tweaks tool as well.
- You should see the manually installed GNOME extension in the Tweak tool now.
- The new installed extension can be configure or enabled in the Tweak tool.
