I have tried a few of the fixes on the forum, but none have worked.

Hello azazelblackraven,

Probably a rhetorical question, but do those few fixes include going to the 3-bar menu => Customize and see if the icons are there ? And if they are : drag them to the toolbar  ?

You can check the Browser Console for messages related to these extensions.

• "3-bar" menu button or Tools -> Web Developer

Yes, that was rhetorical. But thanks for the thought.
