I’m having the problem periodically.

I’ve also tried diabling all related plugins (Better Greader and Stylish and GreaseMonky), without any success. Sometimes a reload of google reader helps, sometimes it helps waiting some hours.
I visit other pages, where I deffinitely don’t use style scripts and they too sometimes and only sometimes render strange like if Firefox doesn’t know how to parse css or page layout.

Could it be a bug in Firefox?

You need to go to the options in the menu for Firefox.

Once the options pop-up comes up select the Privacy tab and in the ‘Private data’ section click the ‘clear now’ button (the last button in the privacy tab).

In the new pop-up select the check boxes next to Cache and Authenticated Sessions and click on the ‘clear private data’ button.

Close all the windows and pop-up and restart Firefox. Start Firefox again and you should be able to access Google Reader.

It did not work for me the first time around but when I ran through the steps again it worked!

Let me know if it does not work for you.

I would definitely like to know why this happens. Seems like the cache or cookies used by Google Reader are faulty or is it something else?

Please let me know by emailing me at pali dot madra at the rate gmail dot com.

I stretched it out to a 2g, but ended up taking it out due to job concerns and the possible horror of actually chipping one of my teeth.

And excellent name, ps!
