[Mar. 15 update: added information about Firefox ESR 52 64-bit]

Mozilla Firefox 52 Extended Support Release (ESR) is certified as a Windows-based client browser for Oracle E-Business Suite 12.1 and 12.2.

What is Mozilla Firefox ESR?

Mozilla offers an Extended Support Release based on an official release of Firefox for organizations that are unable to mass-deploy new consumer-oriented versions of Firefox every six weeks.  From the Mozilla ESR FAQ:

What does the Mozilla Firefox ESR life cycle look like?

Releases will be maintained for approximately one year, with point releases containing security updates coinciding with regular Firefox releases. The ESR will also have a two cycle (12 week) overlap between the time of a new release and the end-of-life of the previous release to permit testing and certification prior to deploying a new version.

Maintenance of each ESR, through point releases, is limited to high-risk/high-impact security vulnerabilities and in rare cases may also include off-schedule releases that address live security vulnerabilities. Backports of any functional enhancements and/or stability fixes are not in scope.

At the end of the support period for an ESR version:

  • the release will reach its end-of-life
  • no further updates will be offered for that version
  • an update to the next version will be offered through the application update service

E-Business Suite to be certified with Firefox Extended Support Releases Only

New personal versions of Firefox on the Rapid Release channel are released roughly every six weeks.  It is impractical for us to certify these new personal Rapid Release versions of Firefox with the Oracle E-Business Suite because a given Firefox release is generally obsolete by the time we complete the certification.

From Firefox 10 and onwards, Oracle E-Business Suite is certified only with selected Firefox Extended Support Release versions. Oracle has no current plans to certify new Firefox personal releases on the Rapid Release channel with the E-Business Suite.

Plug-in Support removed in Firefox Rapid Release 52

Mozilla has removed plug-in support in Firefox Rapid Release 52.  This means that the Rapid Release version of Firefox cannot run Forms-based content in EBS. 

Firefox Extended Support Release continues to offer plug-in support.  End-users who need to use Forms-based content in EBS must run the Firefox Extended Support Release. 

Plug-in Support removed in Firefox ESR 52 64-bit

Mozilla has removed plug-in support in Firefox ESR 52 64-bit. This means that the Rapid Release version of Firefox cannot run Forms-based content in EBS. 

Firefox Extended Support Release 32-bit continues to offer plug-in support.  End-users who need to use Forms-based content in EBS must run the Firefox Extended Support Release 32-bit version. 

Will EBS offer an alternative to plug-ins?

Yes. We are working on an update to EBS that allows Forms-based content to run in browsers that do not have plug-in support.  See:

When will the new Java Web Start alternative be released?

Oracle's Revenue Recognition rules prohibit us from discussing certification and release dates, but you're welcome to monitor or subscribe to this blog. I'll post updates here as soon as soon as they're available.   

EBS patching policy for Firefox compatibility issues

Mozilla stresses their goal of ensuring that Firefox personal versions will continue to offer the same level of application compatibility as Firefox Extended Support Releases. 

Oracle E-Business Suite Development will issue new E-Business Suite patches or workarounds that can be reproduced with Firefox Extended Support Releases.  If you report compatibility issues with Firefox personal releases that cannot be reproduced with Firefox Extended Support Releases, your options are:

  1. Deploy a certified Firefox Extended Support Release version instead of the Firefox personal version
  2. Report the incompatibility between Firefox ESR and Firefox personal to Mozilla
  3. Use Internet Explorer (on Windows) or Safari (on Mac OS X) until Mozilla resolves the issue
EBS Compatibility with Firefox ESR security updates

Mozilla may release new updates to Firefox ESR versions to address high-risk/high-impact security issues.  These updates are considered to be certified with the E-Business Suite on the day that they're released.  You do not need to wait for a certification from Oracle before deploying these new Firefox ESR security updates.

    Worth noting that ESR releases will no longer be supported by Mozilla from early 2018


    "In case you’re not yet ready for this transition to happen, the ESR (Extended Support Release) of Firefox 52 will continue to support these plugins until early 2018."

    So if like us you have users on Firefox, it may be time to transition to a different browser completely rather than moving to an ESR, otherwise you will be having to do this anyway in a few months, depending on when Oracle release their fix for this issue.

    It makes it quite hard to plan without a date from Oracle when they will support non plugin browsers.

    One thing you may want to mention upfront is that the 64 bit version of firefox 52 ESR doesn't support NPAPI either. Please install the 32 bit version of the ESR to run EBS. I found this out after installing the 64 bit version.

    Thanks; good suggestion, Greg. I've updated the article with that information.
