If you are using several web browsers either on one computer or multiple systems, you have probably noticed a few features that one browser supports, while the other does not.
The only option to get access to useful features in browsers that do not support them is to install browser extensions which add them to that web browser.
This is obviously only working if extensions exist that offer this functionality, and if the extension API of the browser supports these features. If that is not the case, then it may not be possible to use browser-specific features in another web browser.
One of those extensions is the Classic Opera add-on for the Firefox web browser. It adds a number of Opera features to the Firefox browser. Most of the features it adds are supported by Opera but not by Firefox.
While you may notice that some are supported in a different way, Shift-click to close tabs instead of middle-clicking for the same effect, others are not and are unique to the extension.
The Firefox add-on adds the following features to the web browser:
As you can see, most features are tab and toolbar related. One of the biggest issues that users may run into is that there is no option to disable select features added by the extension. If you do not want your bookmarks toolbar above the tabbar, then you cannot install the extension as you cannot change that. The same goes for the address bar underneath the tabbar.
If you like that layout, or do not use the bookmarks toolbar or navigational toolbar in Firefox, then you may find the extension quite useful.
Classic Opera adds several interesting features to the Firefox web browser. The main issuer here is that you cannot customize the feature set as there are no options to do so. It is either take all or none, and that is problematic if you like some of the features but do not want to use others.
