Contextual filter on taxonomy view using URL
Create a view, Create a page display and set it's path to features/%

Then add a contextual filter: Taxonomy term: name.

That's it! when you visit the page /features/blubbles page, if there is a taxonomy term named blubbles, the views will display the fields you have added. You may add a validation criteria (while adding the contextual filter) to limit terms to an specific vocabulary.

However you might want to consider using panels too. After enabling panels, page manager and views content panes modules, you can create a page and set it's path as features/%term (notice the arg is %term not %) set it's type as String.


Add a display to your view of type content pane
Add the contextual filter, taxonomy term: name.
In configuration section of the views display there is a 'argument input', open it and set type of argument from panels argumen
In the opened configuration popup, select second argument as the name is second parameter in your path. you may select from panels context too if you can configure the panels accordingly.
Go to panels configuration page, add content to one of regions, select views panes not regular views!
Visit the panels page, done.


This way you have more control over your page. you can create another views, such as a view directly showing nodes, filtered by a taxonomy. you can send the term name just like you sent in the views above. 
In the first view it's not a good idea to show nodes if you are only planning to display the term fields only once.

This question : Contextual filter with a block view is about views blocks and contextual filters. I still suggest using pages. views content pane will play role if a block for you.
