Following is a copy of the stderr output from Mozilla Firefox startup [scripts] where the Firefox is running under Linux on the HP laptop, and the X11 display is running on the Sony Vaio laptop under WinXP - Cywin-X, it is.
Not having looked these up, yet, I'm reasonably certain that the first two - the nss-shared-helper errors (or information messages, depending on your POV) are coming from the Linux host configuration - that 'NSS_[...]_SHARED_DB' business harks back to ... was it Netscape 3.x under RedHat Linux?
The Pango-WARNINGs are doubtless a function of the X11 Font Configuration for the Cygwin X11 server - that would mean a problem on the WinXP host - needs the X11 font server configuration tweaked to correctly serve Pango fonts.
The last error message - the one tagged with the [NoScript] identifier is clearly a Javascript error from a Firefox Add-On (NoScript) which is probably doing something like assigning XML values to User Interface Document Object Model elements.
If you fix any of these, and record the fix in a blog, wiki, or other online media, email me (or post a comment here) and I will link to your site. Meanwhile, this will just have to wait until iut becomes a priority.
