Firefox Portable

Microsoft Compliance

Submitted by lonpm2 on August 4, 2022 - 6:56am

My employer has now implemented a Microsoft check to ensure that we only run an up-to-date and supported browser. The portable apps version of Firefox fails this check. The alert message states that Chrome, Edge and Firefox are supported apps and that Firefox needs to be newer than version 91.
However I checked help in the version of Portable Firefox that I have and it states it is at version 103.0.1. It shouldn't fail the check therefore as far as I can tell.

I just downloaded FirefoxPortable_103.0_English.paf.exe from The web page shows SHA256 Hash: 7c4bf6c69abb778ae7f64130e8873246ffcc117c4f8bdc9d8f0cede4731365a8 (English).

My local check gives a SHA256 hash of 31F738DE4B2E668A45F9DD24356ED377AC5ED38B1CE9E4AC755B0C513AAD6C41

When I click on the PortableApps Antivirus Scan link (which passes the 7c4... hash ), VirusTotal gives me a Not Found, but when I search VirusTotal using the 31f...hash, it comes up with:

Question about how to update Firefox Portable.

Submitted by gaveitatry on May 22, 2022 - 12:00pm

There have been a few times when I updated Firefox Portable through the browser itself. But the vast majority of the time, I use the PortableApps program to update it. Is either fine, or should I only do it through the PortableApps program? The reason I ask is because it would be faster to use the browser instead because it usually takes 1-2 days before the PA program prompts for an update. And if I did it through the portable browser, I probably wouldn't ever have to launch PA since Firefox Portable is pretty much the only PA program that I use.
