Which add-ons and extensions do I disable and enable to permit files to be uploaded to e-mail as attachments?

Each time I attempt to attach a file to an e-mail, I receive the following error message "your file upload has failed, please try again". I use Windows XP and have removed Firefox and reinstalled the browser to the latest version as well as a previous version. I am wondering whether an add-on or extension needs to be disabled or enabled that would allow any file to be attached.

Worst case senario is to use trial and error. Disable all and enable one by one.

Please update your plugins to the latest version. Check to make sure you are up to date:
