  • Very poorly made extension, don't install! It causes a huge slowing of the page. On almost every page I visit, I have a yellow warning window on the top (it's from Firefox, it's not a malware) saying that Diigo causes big slowing down. Plus, I'm more and more unhappy with this service, it's too expensive, and free account is way too limited. Worse and worse.
  • Very usefull!!
  • In last versions of Firefox (at least in Firefox Web Developer Edition, which is were I had this installed) this extension has/causes a memory leak, at least with you have too many tabs. It devores all the memory available and then, the machine get frozen and I need to reboot :). It goes from 6-7 gigas of normal usage (in my PC, because the software I have usually running, of course) to all my 16GB, in 1-2 minutes. It's crazy.
    I uninstalled it, because, in fact, I'm not using this extension for a while, but I just comment for you to be aware of it.
    Probably, this extension not being updated since last November doesn't help at this.
  • thanks for app ok
  • Thank you for this app, very helpful, buy it ever month.
  • Long time user here. Extremely useful addon but the firefox version needs some more constant love... kinda feels second to chrome.
  • This is a great add-on I've been using for several years as a premium user. That said, it seems the development of the Firefox version halted or at least slowed down. The last version in Firefox is from Nov 8 2017 vs July 2018 for Chrome. I've noticed several bugs and things that do not work anymore. Judging by the ratings in both platforms it seems Chrome users are getting a better experience. This is unfortunate for me, as I like Firefox better than Chrome. My rating is in good faith for now but if they let the Firefox version die I will drop my subscription.
  • No longer works for me in Firefox (running on Linux). For several WEEKS, clicking on ico asks for login, goes to web site, logs in... then clicking on again icon will *very* briefly display the working menu, but that is quickly replace by a login prompt. This will repeat forever. The extension never understands that I have logged on. The product is now useless for me. EDIT - The problem seemed to be a conflict with the add-on "First Party Isolation." I disabled that and I can now log on. The Evernote add-on seemed to have a problem with First Party Isolation too. But not of my other add-ons.
  • your own structured library for quick reference.
  • Very easy to mark sites, and then create an outline is amazinf
  • I am continually told that Diigo Web Collector is slowing down my Firefox browser. Is there a solution for this as I like using both products.
  • Excellent!
  • Top notch tool for managing a lot of dissimilar information. Helps me track things and respond intelligently.
  • This is the web storage system that I have wanted for many years. Annotate webpages (like Edge wishes it could). Easy to use. Good system for adding tags, searching, organizing links. Access it from any browser. The add-on for Firefox seems to work perfectly. I would give it 6 stars if I could.
  • There are annoyances, such as excessively poups but it is interesting to try. I have all my bookmarks there, so I cant to change.
  • Wonderful library tool, practical, and great support
  • Amazing help with learning and organizing research!
  • I use Diigo since 2009, to have on hand all the bookmarks of pages I want to keep, for future revisions. Indisputably Diigo is the best.
  • Fantastic!!
  • Just awesome!
  • Excelente por donde lo mires.
    Muy útil cuando necesitas sacar notas o apuntes de varios sitios web y no te interesa andar copiando o resumiendo dicha información.
    Lo uso en el ámbito académico y profesional. Me da mucho resultado.
    Sería muy positivo mejorar la integración con Safari de MAC OS, eso no funciona del todo bien.
  • Closed sourced vendor lock in. During export they do not add commas into tags, added date, modified date, do not escape < > inside description so totally breaking import into Firefox. During export into IE they do even less. Firefox sites shows it is MPL, but it is not. Diigo does not properly supports Firefox on Ubuntu.
  • I have used it for over 10 years and it is perfect for keeping and organising information on the web.
  • good plugin
  • easy, fast, useful, clean. Great tool to organize informations.
