Features Tooltivity's expert score for the 'Features' aspect of each extension. | 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. ![]() | 9.0 AdBlock Max offers comprehensive functions for blocking advertising, including pop-ups, banners, and video ads. Ad blocker ![]()
These additional functions are hidden at the bottom of the settings and can be activated. There is also a website whitelist on which no advertising should be blocked. ![]() Privacy Security Winner in this category |
Performance Tooltivity's expert score for the 'Performance' aspect of each extension. | 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. | 8.3 Basically, the extension runs smoothly without any performance problems. Page load times are shortened by blocking advertising. Winner in this category |
Design Tooltivity's expert score for the 'Design' aspect of each extension. | 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 The design of Diigo is outdated and could use a modern refresh.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. | 8.8 The user interface is clear and intuitive. In particular, the filter customization options are very clearly displayed in the extension pop-up. Winner in this category |
Value for Money Tooltivity's expert score for the 'Value for Money' aspect of each extension. | 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. | 9.0 If you take a closer look at the extension in addition to the basic functions, you will see how many additional functions are available. As a free web extension, the price/performance ratio is very good. Winner in this category |
Ease of Use Tooltivity's expert score for the 'Ease of Use' aspect of each extension. | 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. | 8.0 The tool is uncomplicated and easy to install. Due to the well-designed method of a slider for the strength of the filter mode, preferences are easy to configure for everyone. Winner in this category |
Security & Privacy Tooltivity's expert score for the 'Security & Privacy' aspect of each extension. | 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. | 8.5 AdBlock Max offers privacy protection through the additional function to prevent tracking. The extensions' data is protected by industry-standard measures. Winner in this category |
Conclusion A summary of our findings and final thoughts for each extension. | Diigo is a handy tool for collecting stuff from the web, like bookmarks, highlights, and notes.
| AdBlock Max is a good tool for anyone who wants to block advertising quickly and easily. It also has additional features for those with a little more technical knowledge. Unfortunately, these are somewhat hidden for beginners and are described via external GitHub links.
