Have used this Add-on for years but the Find Next and Find Previous arrows are dead. Rated 4 out of 5 stars

Have used this Add-on for years but the Find Next and Find Previous arrows within the Find Bar are greyed-out and renders this Add-on as unusable. I wish there was a fix for this so I can continue using it with FF 55. Thanks!!

Otherwise, this is one of my favorite add-ons since search engines no longer highlight cached keywords which makes this Add-on a must.
