Adding URLs to firefox visited history links
2014-07
Is there any way to add links to firefox history like bookmarks? I want Firefox remember those as visited links without opening them
No. You can open the links so they are shown in the history, your alternatively you can use bookmarks. The sole purpose of history is to list what you've shown. Because it is not common to use history as bookmarks, there's no way you can add links to the history like you can with bookmarks.
Have you looked into combining history and bookmarks?
I want to prevent or block URLs of specific domains from being saved or shown in my history. I want to be able to go to these certain websites normally, just not have them saved and not have to use private or incognito mode.
For instance, I don't want any of Google's search result pages to be saved in my history since then when I use the awesomebar I get a lot of Google's search results, which are of no use to me.
Of course I can keep on deleting them, but I would like a way to specify that any URL starting with www.google.com shouldn't be saved.
I still have yet to explore how this can be done manually.
But for now you can use HistoryBlock Addon. I believe it answers your requirements.
Either of these should help:
