How to Remove Duplicate Bookmarks in Firefox

When you find an interesting website, TrishTech.com for instance, you add it to your bookmarks list so that you can visit it later easily without having to look for it. In Firefox, bookmarking of websites can be done either by pressing the hotkey Ctrl + D or by right-clicking over a page and selecting Bookmark this page. But sometimes we bookmark a website more than once, without realizing it. This results in having the same website bookmarked under different categories multiple times. If you want to remove the duplicate bookmark entries, then you can can make use of the Bookmarks Deduplicator plugin for Firefox.

Once the extension is installed, you can go to the Firefox Addons Manager, by pressing the hotkey Ctrl + Shift + A. Click on the Options button next to the Bookmarks Deduplicator extension.
