This is the seventh beta release of Firefox for OS/2 and OS/2-based systems which updates Firefox to the latest release of the 38 ESR lifecycle. The Beta 7 release also fixes a couple of regressions from the previous Beta 6 release, brings the Open in New Tab functionality back, improves font rendering furthermore and enables MP4 video playback in HTML5 content using FFmpeg libraries.

Note that starting from this release, we no longer support manual installation of Firefox requirements from ZIP files and therefore the corresponding information was removed from README.OS2. You should use either the Arca Noae Package Manager or the YUM command line tool to install the following packages in order to be able to use the Firefox application:

libstdc++6 nspr nss libicu pixman cairo pango fontconfig freetype libkai

If you don't know how to do that, you will find more information in the Installation section of the README.OS2 file (the link to the online version of which is given below).

NOTE. In this release we temporarily disabled printing using native OS/2 printer drivers due to technical reasons. An attempt to print to any printer using the Print Dialog will cause a warning message box saying "An error occurred while printing". You may still print to PDF or to Postscript if needed (see README.OS2 for more details about printing).

The CHANGES.OS2 file contains a more detailed list of changes.

The README.OS2 file contains software requirements and detailed installation instructions.


  1. If you find a bug (which is likely), please create an issue at the issues page. But before you create a new issue, be sure it is not already reported by searching through the existing ones using the Search field at the top of this page.
  2. When Firefox crashes it creates a trap report that may contain useful information for the developers. These reports are saved in .TRP files created in the directory where firefox.exe is installed. By default these reports contain only basic information. In order to make them even more useful (and therefore make a fix for your problem much more likely) please do the following:
    • Install the latest EXCEPTQ runtime from (currently, this one is the latest).
    • Install the Firefox symbol files by downloading the firefox-dbgsym archive from the link below and unzipping it to the same directory where you installed Firefox.
    • Make Firefox crash again and attach the resulting .TRP file to the issue describing your problem.
