I was going to post this as a question but it's clear the browser does not have this function so it fits better as a suggestion. It's something I took for granted in my previous daily browser (IceDragon) but have been frustrated by its absence in Opera.

Scenario: You're browsing a particular theme but don't have time to read every page you found so bookmark the ones remaining for the future in their own folder. A week later you're interested in that theme again and are browsing similar pages but again run out of time, you bookmark the remaining pages which may include the same pages from the first session, but in a different folder.
The next day you have ample free time and view the most recently bookmarked pages and click the bookmarks button to un-bookmark them as you have now viewed the pages.

Problem: But the bookmark button only removes the most recently added bookmark for the page, not the older instance that's also saved in a different folder. Six months down the line you might be browsing that theme again and end up viewing pages you'd already absorbed because you have them bookmarked still which means they're unread to you.
Even bookmarks added to the same folder are treated as individual instances. I added a BM for a Youtube video earlier this week and inadvertantly added the exact same one a couple of days later. I watched the video yesterday and as usual unchecked the BM icon to delete the bookmark but I note this morning the first bookmark I added for the video is still there. This is what led me to search for the function to "delete all with one click": Opera doesn't have one as far as I can see.

Suggestion: While I can see how this feature might be annoying for some who want to keep pages forever, I'd at least like it as an option to remove all identical bookmarks with a click of the heart/bookmark icon. Like I said, I took it for granted in the previous browser but it prevented me accidentally retreading the same steps. And if I do happen to come across a page or video that I'd previously put aside "for later", it also tidies up my saved BM's folder by removing age-old instances of the bookmark after I've read the page.

Thanks for reading, and for your consideration!

@burnout426 said in One click removal of identical bookmarks.:

As an alternative to a built-in feature (and not one-click like you want), you can try some of the extensions at https://chrome.google.com/webstore/search/duplicate bookmarks?hl=en&_category=extensions.

That's better than nothing, thanks. Started using the top-rated one "Bookmark Dupes". It requires a periodic manual search but does solve the problem i was having. Thanks again.
