Remove duplicate bookmarks in Firefox
Bookmarks are both my bread and butter and also the bane of myÂ existence. Honestly, I began collecting them in the mid 90's and still have the same file, although a steadily added-to version of it.
In the early days I backed up the file to a CD and later an external hard drive. Then Xmarks came along to save me. Now Xmarks-like ability is built right into browsers like Chrome and Firefox.
However there are two big problems with my growing 15 year old collection -- it contains duplicates and it is rife with broken links. Today I want to look at a way to solve the former and in the future we will tackle the latter.
Update: Bookmark Duplicate Cleaner is not compatible with Firefox 57 and newer. We suggest you use the compatible Bookmarks Organizer instead. Bookmarks Organizer detects duplicate bookmarks but also broken and redirecting bookmarks. End
Bookmark Duplicate Cleaner
A Firefox plugin called "Bookmark Duplicate Cleaner" is the tool I decided to use for this task. Once installed, it is accessible by clicking on the Tools menu and then BookmarkÂ DuplicateÂ Cleaner.
The app will immediately pop up a box that displays two columns. The left shows the duplicates that have been found and clicking one will display where it is duplicated within the right column. The bottom gives you an option to open the bookmark if you care to double-check it. However, the Delete button is probably what you will want to use in the vast majority of occasions.
The extension is very simple to use, but if you have a lot of duplicates found then you may expect to spend some time here. However, if your bookmark file has become asÂ unwieldyÂ as mine then apps and extensions are pretty much the only way to solve this problem.
If you are looking for a Chrome solution then you may want to check out SuperSorter which can do a similar thing. As for Bookmark Duplicate Cleaner, it is new -- version 0.1 -- but it holds some promise and will likely provides quite a bit moreÂ functionalityÂ in the future. For now, though, I still found it useful in cleaning up some of my multitude of bookmark problems.
