Firefox recently caught a virus when I opened a supposedly reputable website, so I had to uninstall and reinstall Firefox. Now, several of the previous features are gone. Most notably, the bookmarks icon (three bars) that used to drop down to show all my saved bookmarks now does nothing. In addition, I am no longer able to edit the names of my bookmarks. When I fill in the blanks in the "edit bookmark" function, the OK button is greyed out and not active.
