That is an indication of a problem with an add-on that is not compatible with Firefox 4 beta. You can try disabling your extensions until you find the one causing the problem. See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems for more details on how to fix this.

I see by your user agent string that you have the Ask toolbar, I don't think that toolbar has been updated to work with Firefox 4, try disabling that one first.

I got an error message while copying a text and pasting it into google translation section on Firefox 4.0 Beta. It says "Do not have enough storage space to process this command." This happened after doing some copy and paste work. I mean it didn't happen at first.

There are three successive error messages before firefox starts. With the RC version the browser will load, in Beta 11 it would open but not connect to the internet. These are the messages.

These addons were recommended and I installed them, Addon Compatibility Reporter and Feedback. This is when the problem first occurred.

I get similar errors. When I log onto some of my most used sites, the images don't appear and the site is almost entirely text. This does not work with bitmapped link images on sites like http://news.nnyln.net/feedback.html where I depend on the newspaper articles for genealogy research.

When I go to sides like http://www.cdcovers.cc/list/dvd/a and try to download cover art, if get a "TypeError: 0ticket undefined" message.

How do I correct this?
