I have been using TrustFax with my Windows PC but am considering
changing to Ubuntu Linux rather than go to Windows Vista.
Will I be able to use TrustFax with Firefox and Ubuntu Linux? Will I
be able to upload OpenOffice .doc files and fax them?
trustfax does not support Ubuntu Linux at this time.
Although trustfax is a web based application (no software to install), the browser is the biggest issue with the trustfax site. The operating system will effect how the browser will operate when accessing some web pages. So your Linux and Internet explorer may work but it is not listed as a supported browser and operating system on TrustFax.
