no scrolling after update
All of a sudden, after Firefox on my Mac desktop updated today, I can no longer scroll on any webpages with my mouse. The right click button also doesn't seem to do anything.
I saw other problems about scrolling that said to delete cache/cookings and did that, but it didn't work.
I can only see the vertical scroll bar on a page if I resize the window, and even then, it only stays up briefly.
Is this an issue with the update itself or did something likely happen on my end only? What next?
