By default Firefox Find searches on all the things availble within the open window i.e both text and links. What if you want to search only the text in links or hyperlinks ? Just hit Win Key + single quotes ( ‘ ) and you would see quick FInd ( links only ) search box appearing at left bottom of the browser window.
Just type in and you would see searches being made on Links only. Its really cool and never knew it existed unless I accidently hit it.
PS: In case you have any text editor in browser or any other window which conatins editor it might not work. At least did never worked for me.
