Current link context menu on the one hand is too dense - I'd move all extension in a separate group, and also not dense enough -instead of 3 same lines for opening a link (that waste a lot of space on the left forcing the text to not fit in a single line) I'd use a single line with full width, bigger height that has 3 sections with only icons and section width depending on the use frequency (eg, private tab could be smaller, new regular tab would be biggest)

So something like this

Ideally you should be able to apply fully custom styles to these menus, reorder/group/position however best fits your use
