You can make the menu bar in Firefox semi-transparent like Google Chrome. When you type an address or search query into the address bar in Google Chrome, the drop-down list of history and search suggestions that appears is slightly transparent. Nothing extreme, but it adds a nice touch.
Here’s a quick trick that can make your Firefox menu bar semi-transparent like in Google Chrome.
Follow the steps below (note: this is for Windows only):
1. Close your Firefox.
2. Open your Firefox profile folder by entering the following in the address bar in Explorer or in the Run command:
%appdata%MozillaFirefoxProfilesSee the screenshot below:
3. Open the default folder, and then open the Chrome folder in it.
4. Open the userChrome.css file in an editor such as Notepad. If you do not have a userChrome.css file, open the userChrome-example.css file instead.
5. Add the following code to the end of the file:
#PopupAutoCompleteRichResult[type="autocomplete-richlistbox"]
{
opacity: 0.9 !important;
}6. Save the file as userChrome.css in that same folder.
7. Open Firefox, and now your Awesome Bar’s drop-down list will be transparent. Actually, it may look even more awesome than Google Chrome’s address bar!
