Let's start with the toolbars. Do you have any of the toolbar area, including menu bar, tab bar, etc.? If nothing appear, check that you are not in full screen view. The F11 key switches between full screen and normal views.

If an individual toolbar is missing, you can try one of these methods to display it:

• right-click a blank area of the tab bar
• right-click the new tab "+" button on the tab bar
• tap the Alt key > View menu > Toolbars

Any luck?

Regarding your bookmarks list, there are 4 possible ways to get at the list:

• Drop-down menu from the classic menu bar or orange Firefox button
• Drop-down menu from a toolbar button
• Bookmarks Sidebar (Ctrl+b)
• Library dialog (Ctrl+Shift+b or "Show All Bookmarks")

Could you check and report back on which ones are working and which ones are broken?

Thanks. Tried to follow your instructions but was not real successful. However, I did use the F11 button and saw the effects there. Regarding the bookmarks: I went to them and noticed that they all presented with a full page except one which I reference frequently. So I deleted the bookmark and then re-entered it and then it worked. I'll try again tomorrow to make sure it functions. Can't believe how many hours I spent trying to figure this out. Again, thanks for your time and trouble.

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot.

Opening in the sidebar is the default for bookmarks that are created via a link or button on a website. You can check the properties of a bookmark via the right-click context menu in the sidebar (Ctrl+B; Command+B on Mac). In the Bookmarks Manager (Bookmarks > Show All Bookmarks) you can click the More button in the Details pane at the bottom right. Make sure that "Load this bookmark in the sidebar" is not selected.
