Here are my issues, in order of priority, with the first issue being the one I care to have addressed the most. -I'm OK with the downloads being moved to this awkward new "Library" window. However, the main issue I have right now is that the Library window doesn't appear automatically upon starting a download. I'd like it to. Please point me toward an option to allow me to do this or please implement this, since it seems to me to be a necessary feature for this transition, considering helpful functionality was lost. -I'd like to be able to hide the left panel with a toggle button at the top. This would help to complete the convenient and compact visible UI for checking download progress. -The downloading progress bar in the Windows taskbar should be on the "Library" taskbar button instead of the main Firefox taskbar button, to indicate that a non-website file is being downloaded and it's visible in the Library window. -Please re-add "Open File" to the right-click menu for downloaded files in the Library window. I realize double-clicking on the files works to do this, but it's not obvious and I used to right-click and click "Open File". -There is an ugly and pointless column on the left side of the right-click menu for downloaded files. As you can surely tell, I was satisfied with the "Downloads" window that existed before this version and I would definitely prefer it with its full functionality (which is still not addressed by the addon, https://addons.mozilla.org/en-US/firefox/addon/downloads-window/ ). Also, frankly, I would prefer the nice functionality to be inside Firefox without any addons. Having the window appear upon downloading a non-website file is a very user-friendly feature and should still be accessible at least optionally.
