If you visit the official Google Chrome extension gallery you notice that there are quite a few ways to sort the extensions. It is for example possible to display extensions sorted by popularity, date or rating. If you compare those filters to the ones offered at the Mozilla Firefox add-ons portal you notice that some filters are missing. This includes extension categories and the ability to only list languages that have are available in a specific language.
If you go to the Chrome extension gallery you notice for instance right now that six of the ten extensions on the first page of the recent filter are not in English.

There is no option to display only English extensions or extensions in another specific language. The second missing filter is a category filter. A user looking for security extensions or social networking add-ons has currently only the option to either look through all the extensions to find one that is related to that category or to perform a search hoping that the keyword will list all the relevant extensions that are available.
Both options are not that reliable or at least very time consuming. The Chrome gallery needs categories and language filters, something that the developer’s should borrow from the way Mozilla offers those on their pages.
Several third party Chrome extension websites, such as Chrome Extensions, use categories to list the extensions.
