Features & Capabilities

Bookmark Detector is a lightweight Chrome extension designed to help you maintain a clean and organized bookmark library by automatically detecting and removing duplicate bookmarks upon creation. Whenever you add a new bookmark, the extension checks for previously saved bookmarks with the same URL (ignoring differences after the '#' symbol) and removes duplicates instantly while notifying you about the action.

The extension includes a convenient on/off toggle, resetting with each browser restart, giving you control over its operation. It prioritizes your privacy by not storing or sending any data. Bookmark Detector is an essential tool for anyone looking to avoid clutter and maintain a streamlined browsing experience. The source code is openly available on GitHub, welcoming contributions and bug reports.

I like avoiding duplicate bookmarks. I guess, once installed, it will work without noticing. So I tried to bookmark a site I already bookmarked, to see what happens. "When at least one is found, it will remove the freshly created bookmark and show a notification about it" The new bookmark was made and the old one is gone. I thougt it must be the other way.??

I don't know how to activate it, maybe it only works when adding new bookmarks? There is one thing i would like, I can't find it anywhere. it is a bookmark addon that goes through all your bookmarks and tells you first which ones work and which ones don't, because some bookmarks I've had for more than 20 years and they don't work anymore, only going through 500+ is a hassle to remove individually. Perhaps this could give option to auto search all bookmarks and in the background test them out to see if they are working or now malicious links instead. Testing if they not only work but if they are malicious links or not?

Is Bookmark Detector Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Bookmark Detector requires very minimum permissions.

Risk impact analysis details

Medium Access to bookmarks may provide insights into user preferences and interests but generally carries low risk.
Medium ******* ******* ************* ***** *** ** ******* *** **** ******* ****** ******** *******

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Bookmark Detector has earned a fairly good reputation and likely can be trusted.
