This undead add-on intrudes on _every_ text box, yet FF states that it's not installed. Am I cursed for eschewing the upper case? If I ever added it, I've since removed it. Its omnipresence taunts me.

When using with Google Docs, the highlight in the text field shows less than half the times it's supposed to, while in Edit mode. When using the side bar to select corrections, if they are not highlighted the document scrolls down to random pages some times. And sometimes when going back to the document from the side bar, it had a yo-yo effect when trying to scroll at first.

Very handy corrections.

There too much lag with this app while typing
