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. ![]() Winner in this category | 7.0 SetupVPN offers basic VPN functions with limited free access. With free access, you have the choice of 5 countries to log in to for 30 minutes at a time. When using the premium version, these limitations do not apply, but here too there is a lack of advanced security features like those offered by competitors. |
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. Winner in this category | 4.5 SetupVPN offers basic performance for occasional use. The free version has limited server locations, but the premium version offers better speed and reliability. |
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 The design of Diigo is outdated and could use a modern refresh.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. Winner in this category | 7.0 The design of SetupVPN is simple and intuitive. However, the layout in the free version is very dubious and annoying due to the excessive number of advertisements. 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. Winner in this category | 6.0 In this category, the extension performs completely differently if you are looking for a free or premium extension. |
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 Setting up the extension is straightforward. A connection can be established immediately after installation and you can even test whether the connection works. Nobody should have any problems here. 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. Winner in this category | 5.0 SetupVPN offers only basic privacy protection, with limited security features. However, the many advertisements in the free version raise concerns about data collection. Many who use a VPN want to use it precisely so that their data is not stored. From our point of view, a VPN service with such many advertisements is very dubious. |
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.
| SetupVPN is a good choice for users who are only rarely looking for a simple, free VPN service. While it offers privacy features, it has strong drawbacks, such as dubious frequent advertising and limited free access. For those who need more robust privacy and security features, the premium version might be worth considering, but there should be better alternatives. Overall, we agree with the current reviews from other users that there are much better alternatives. |
