I have had about:config >dom.storage.enabled, set at false for a week or so now. There were no problems until the ff 3.6.12 update yesterday morning when I began having the same problems as all of you. I allowed all scripts, problem still persisted so I went back to about:config, toggled dom storage to true and voila, chat and compose started working again. Just to check, I switched it back to false and it stopped working again. You can use the add-on betterprivacy to autodelete dom storage cookies but it looks like google will no longer allow you to disable them completely.

Perfect - solved the problem. Thanks!

Hi yeltb, I followed your instructions but whether I have dom-cookies set at true or false makes no difference in my case. I still can't compose or reply to mail while in the standard format. As for others, it works OK in basic HTML. I also have 3 other problems with Firefox which I assume are probably related to the same problem? 1) When I click "Add content to my zoo" I am not taken to the page where I can do this. I just get a white page with a few lines of text on it. i.e.

      . My Content
      . My Details
      > Read myZOO help  .... etc.

2) I can't view any video on the home page. Clicking on the arrow either does nothing or just refreshes the home page. 3) when I download any file, the download box pops up but nothing gets entered in it. It just stays blank, even though the download does occur. Regards, Ducatiman

I just tried this solution (set to "true") and it DID FIXED THE PROBLEM in Firefox 3.6.12 I also disabled auto-delete DOMStorage in Firefox config, just to be sure. Yep, upgrading to Firefox 3.6.12 was the problem.

Thank you for the fix!

This solution worked for me, as well (compose email, etc. stopped working late afternoon 10/29.) What I'd like to know is how/why this worked, and what the "out of the blue" change was on Fri. evening (no upgrades at that time).

Not sure WHY it stopped working but, I have noticed that I cannot automatically add passwords - not sure if it is connected.

I'm running windows xp still, not win 7. So I'll wait until firefox and or google have a solution as I'm not willing to void any warranties. I'll also send this to gmail so they can take a look at it and make a fix.

Fixed the problem - thanks yeltb

Thank you! Works just fine now!!!

Thanks. That works.

Thank you !!! That solved it for me.

All I did was ..... uninstall Gmail notifier and Problem fix.
