Remove 'Delete Bookmark' from bookmark context menu
Due to the proximity of 'Edit Bookmark...' and 'Delete Bookmark' in the bookmark context menu, I have accidentally deleted bookmarks on several occasions.
I know it's possible to undo deletion of a bookmark in the Library window, but I'd prefer to avoid accidentally deleting bookmarks in the first place. So I'm wondering if it's possible to remove 'Delete Bookmark' from the context menu, at least in the browser window. It doesn't matter whether or not it would remove the option from the context menu in the Library window. As long as I could still delete bookmarks with the Delete key in the Library window it would be an improvement. Alternately, if there's a way to have a confirmation dialog appear when deleting bookmarks that would also be acceptable.

Thanks for the response, but it doesn't seem to be related to my question.
You can add CSS code to the userChrome.css file in the chrome folder in the Firefox profile folder to hide this menu item.
#placesContext_deleteBookmark { display: none !important; }
It is not that difficult to create userChrome.css if you have never used it.
The first step is to open the "Help -> Troubleshooting Information" page and find the button to access the profile folder with the random name (xxxxxxxx.default-release).
You can find the button to go to the profile folder under the "Application Basics" section as "Profile Folder -> Open Folder". If you click this button then you open the profile folder in the Windows File Explorer. You need to create a folder with the name chrome in the profile folder with the random name (name is all lowercase). In the chrome folder you need to create a plain text file with the name userChrome.css (name is case sensitive). In this userChrome.css text file you paste the text posted. On Mac you can use the TextEdit utility to create the userChrome.css file as a plain text file.
In Windows saving the file is usually the only time things get more complicated because Windows can silently add a .txt file extension and you end up with a file named userChrome.css.txt. To avoid this you need to make sure to select "All files" in the dialog to save the file in the text editor using "Save File as".
You need to close (Quit/Exit) and restart Firefox when you create or modify the userChrome.css file.

In Firefox 69 and later you need to set this pref to true on the about:config page to enable userChrome.css and userContent.css in the chrome folder.
