Firefox Nightly: Fix “Oops! your browser seems to have cookies disabled” error with Google services

I have three versions of the Firefox browser installed simultaneously, including Firefox stable branch, Nightly and a special UX build. I use Nightly for my regular browsing tasks very often. Yesterday, I noticed that the browser was preventing me from using the Google +1 service and Gmail as well and Google was showing me the following error message: Oops! your browser seems to have cookies disabled. Make sure cookies are enabled or try opening a new browser window. I had not changed any settings and cookies were enabled, however, the error still continued to occur. Here is how I fixed it.

  1. Open a new tab and enter the following text in the address bar:
    about:config

    Confirm that you will be careful if a warning message appears for you.

  2. Enter the following text in the filter box:
    http2draft
  3. You will see the network.http.spdy.enabled.http2draft parameter. Just set it to false by double-clicking it and restart the browser.
    http2draf

Now Google services will work properly in your browser. This will disable the HTTP 2.0 web standard support, which is in a draft stage at this moment and not ready for mainstream use. If you are interested in the details, refer to Mozilla's bug tracker.
