Cocoon is a Firefox Browser add-on which protects you from virus from web sites and offers secure web experience. I downloaded it after reading it from one of those tech blogs (sorry I forgot which one) and decided to try it two days ago but then it messed up my current open tabs. Now that I closed all those open tabs (I was able to retrieve them), I decided to give it another try.

I logged into my Cocoon account then opened this blog’s dashboard to prepare this post. This is what I got.


It won’t load the Visual tab’s icons. I thought there was an error so I saved the post as draft then reloaded but still no sign of the icons. I tried again then I got this page.

reviewI do not know what ICAP server is but I never got this page before. I reloaded and got the dashboard sans the icons. I logged off Cocoon and reloaded this page and see the result.


The icons are back.

I won’t use Cocoon again because I’m a blogger and I need access to those icons. Cocoon couldn’t even pass my “test.” I’d rather have a less secure web experience than not be able to access the basics of the sites I frequent to.

Other things I noticed about the add-on:

  • It slowed browsing although not significantly
  • It slowed the browser when I use other add-ons (1Password in particular)
  • It doesn’t save your browsing sessions when you close the browser.
  • The preference only offers the following when starting the browser: blank page, Cocoon history, Cocoon places, Cocoon mailslots, and your homepage.

    Hi Karen,

    Sorry that you had so many problems with this plug-in. I also had problems blogging in July with Cocoon – there were myriad ICAP errors and sometimes it would post and at other times it would not.

    The company was very aware that shortly after releasing their new anti-virus scanner that overall problems increased. They have been working diligently on resolutions and this month Cocoon has been pretty reliable.

    I hope you will check it out again and add to this blog post your current findings. Also there is feedback (from within the Cocoon GUI) where you can send the developers feedback. They are also on Twitter, Facebook and have a contact form at

      I contacted Cocoon using the feedback and gave them the link to my review 🙂 I will try Cocoon again one of these days and see if it’s any better.
