I just wanted to put an exclamation point on how well Reader View has evolved in Firefox. Sometime back I posted a criticism (fully justified) about the audio reading functionality of Firefox and I avoided its use (switched over to Edge browser for that use) but recently used the feature in Firefox 119.0 successfully.
What a miracle this is now! It worked beautifully, the highlights of the paragraph on the page and the light underlining of the words spoken was just near perfect.
Thanks to the developers at Mozilla for this feature and a vast improvement over past iterations of this function. Great job
