Here's how I find meaning of Arabic words quickly using Chrome address bar.
Chrome -> Settings -> Search Engine -> Manage Search Engines -> Other Search Engines -> Add.
Now add filling up the form with the followings :
Search Engine : habibur.com
Key world : ar
URL : https://habibur.com/word/?q=%s
Click Save and done.
Now whenever I need to find the meaning of an Arabic word, I type on Chrome URL bar "ar Google helps too, but frequently I find this dictionary more helpful.
