Features	8.5 Ad blocking: The free version blocks annoying advertisements on websites. With the premium version, additional functions such as the blocking of cookie banners or pop-ups can also be activated. Privacy and Security: AdBlock blocks third-party trackers on every Website and protects your privacy. It also blocking malicious ads with malware, scams, and cryptocurrency miners. Sync & Backup: With the Premium version, whitelists and user-defined rules can be synchronized across Chrome profiles.	8.5 Diigo offers basic features for a highlighter and bookmarking tool. It works well and we were able to highlight most websites and they were recreated when revisiting them. The highlighter popup makes it easy to highlight text offering 4 colors. It looks like this: We would have wished to have more color options. Also, note-taking and the tagging functionality are working, but its design does not look appealing. The dashboard where your highlights are stored works well and gives you an overview of all your highlights.
Performance	8.0 The ad blocker extension generally works without slowing down the browser on most websites. However, recent changes at YouTube have meant that AdBlock has not yet managed to ban ads from YouTube again.	8.0 Diigo performs well in terms of highlighting and syncing across devices. The fact that highlights are always synchronized can cause some loading delays. It's not as fast as other highlighters that use an offline-first approach, but it works reasonably well. However, the unreliable link creation feature and the simple sidebar outliner design need improvement.
Design	8.5 The user interface is clearly laid out. With the premium version, you can also use functions to make individual adjustments. You're in control of the look, feel, and font size of AdBlock with easy-to-use controls. There is also the Image Swap function, which will still block ads, but it will replace some ads with pretty pictures of cats, dogs, and nature.	7.0 The design fulfills its functionality. The design of Diigo is outdated and could use a modern refresh. The lack of a nice overview of all your highlights on the page itself means you have to open the dashboard on diigo.com instead. The dashboard on diigo.com is okay, but other highlighters like Web Highlights have a much nicer user interface.
Value for Money	7.5 The free version offers good value for money. Compared to other competitors, the premium functions may be somewhat more expensive. Some premium functions are offered free of charge by other providers.	8.0 The free version of Diigo offers basic features and is fine for most users. The paid plans are reasonably priced and similar to other highlighters. However, we think other highlighters offer more value for the same price.
Ease of Use	7.8 Installation is done in one click. However, you are immediately redirected to a website that informs you that payment is required to use it. However, this is only a voluntary donation. Basic functions are used from this point on. Some settings are set to allow non-intrusive ads and special ads on YouTube, for example. This must first be actively switched off in the settings.	7.8 Diigo is fairly easy to use, but the sidebar outliner takes some time to get used to. You can't see all your highlights on the page itself, so you have to go to the dashboard on diigo.com. We wish there was a sidebar to quickly access all our highlighted pages, like in the Web Highlights extension.
Security & Privacy	9.0 Strong privacy protection through the premium feature malware blocking. The privacy policy is transparent without any indication of data being passed on.	7.5 Diigo takes reasonable steps to protect user data. However, since you need an account and your data is stored in their database, absolute protection can't be guaranteed. We think a highlighter should work without needing to sign up, but this feature is missing in Diigo.
Conclusion	AdBlock is a reliable tool for blocking basic ads. While it blocks most ads and still protects your privacy by preventing tracking, recent updates have failed to prevent ad videos on YouTube. It's a good choice for anyone looking for a simple and reliable adblock extension.	Diigo is a handy tool for collecting stuff from the web, like bookmarks, highlights, and notes. It’s a good deal with its premium plans, but the old-fashioned design and limited highlight colors might be a turn-off. If you want something that looks nicer and offers more customization, check out alternatives like Web Highlights.
