  1. Confluence is a pure Java application and should run on this platform provided the JDK requirement is satisfied. 
  2. While some of our customers run Confluence on SPARC-based hardware, Atlassian only officially supports Confluence running on x86 hardware and 64-bit derivatives of x86 hardware.
  3. Ensure that you configure your Confluence MySQL database to use the InnoDB storage engine as the MyISAM storage engine could lead to data corruption.
  4. HSQLDB: Confluence ships with a built-in HSQL database. While this database is fine for evaluation purposes, it is somewhat susceptible to data loss during system crashes. Hence, for production environments, we recommend that you configure Confluence to use an external database
  5. Internet Explorer 8 and 9 do not support the drag-and-drop functionality of HTML5. As Confluence relies on this functionality, the drag-and-drop experience in Internet Explorer 8 and 9 is not complete.
  6. The latest stable version of Firefox is also supported.
  7. The latest stable version of Chrome is also supported. Chrome does not have WEBDAV / plugin support so features such as Edit in Word for attachments will not work. Please refer to CONF-23322 for information on the progress of the issue.
  8. The latest stable version of Safari is also supported. Confluence does not support editing in Mobile Safari on iOS devices (such as iPhone and iPad). Please refer to CONF-19523 - Getting issue details... STATUS  for information on the progress of this issue.
  9. Confluence is tested with these versions of Internet Explorer in standards-compliant rendering mode, not compatibility mode. Enabling compatibility mode may cause problems because it emulates older, unsupported rendering modes.

    Firefox is now up to version 10, but this page only refers to version 6. Does this mean it hasn't been tested for Firefox compatibility for some time?

    Drag-and-drop doesn't work on Firefox according to this page: Using Drag-and-Drop in Confluence. Worth noting this here, as this would seem to be a compatibility issue?

    PS. Are you aware of a log of spam comments on this page? Doesn't look good.
