Mid June, I began to experience a 6 or 7 second delay or lock up of Firefox when loading a web page or typing in a box like this one.  It happens when the page is loading or when opening a new tab.  I have updated to the newest version of Firefox.  I have un-installed form control panel and started over from a new install.  No change.  My copy of Mozilla 1.7.13 does not do this.  Neither does IE version 6.  I get the same error repeatedly on the Error Console I do not know what it means.  
Error: [Exception... "Component returned failure code: 0x8052000f (NS_ERROR_FILE_TOO_BIG) [nsIFileOutputStream.init]"  nsresult: "0x8052000f (NS_ERROR_FILE_TOO_BIG)"  location: "JS frame :: file:///C:/Program%20Files/Mozilla%20Firefox/components/nsSessionStore.js :: sss_writeFile :: line 2026"  data: no]
Source File: file:///C:/Program%20Files/Mozilla%20Firefox/components/nsSessionStore.js
Line: 2026
When I use the evaluate button it opens a page and highlighted is this:
                 createInstance(Ci.nsIFileOutputStream);
Can anyone help me

Most likely a problem with my computer.  However only happens with Firefox so I'm looking to you for help.
Thank you.
I don't even know what a theme is so it must be default.

Go to your profile folder (see http://kb.mozillazine.org/Profile_folder for how to find it) and delete the files sessionstore-1.js, sessionstore-2.js, etc.
