Previously when I would download a file, the download arrow at the top of the browser window would be green and when I clicked on it it would bring up a window showing all of the current or previous downloads that I had not cleared out. Now, the arrow might turn green briefly, but then quickly goes grey, and when I try to click on it, nothing comes up. In order to see the download window, I have to go to the Firefox menu, and click on the word Downloads.
