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.

[Fixed] Firefox Portable Nightly download error

Submitted by HolyDemon on May 14, 2022 - 2:34pm

Firefox Portable Nightly has a corrupted or an incomplete download file. when downloading straight from, a 1.6MB installer is downloaded and while using that, it shows ''ERROR. file not found 404''. using platform to install nightly shows the error message. only in the case of ''FIREFOX PORTABLE NIGHTLY'', other Firefox variants are fine.

After upgrade to v100 FFportable not usable any more! Retrieve Bookmarks?

Submitted by pstein on May 7, 2022 - 3:40am

I used Firefox Portable (from PortableApps) a long time without problems.
I setup automatic updates.

So my FF updated automatically from v99 to v100.

When I started this new version an error popup appears;

Error: Platform version '100.0' is not compatible with
minVersion >= 99.0.1
maxVersion <= 99.0.1

and rejects to proceed with start.

This is a bug.
I guess its because FF does not understand a 3-digit version number

Ok, I expect that Firefox PortableApps will be fixed.

But there is another problem:

How to run 2 instances of FirefoxPortable simultaniuosly?

Submitted by temptest on May 1, 2022 - 5:24am

I want to run FirefoxPortable and FirefoxDevPortable at the same time but when I try to start the second browser it says Firefox is already running.
Is it in any why possible to run both at the same time?

It is possible to run FirefoxDevPortable and then start an normally installed Firefox instance. So it is possible to run 2 Firefox at the same time, but I want to run 2 Portable version of Firefox.

Matterport VR not opening FF58

Submitted by mozfan on April 10, 2022 - 1:12pm

Matterport used to open and work well, I just had to allow access, but suddenly it no longer opens showing a black screen. Still works in Chrome, but not in Pale Moon. I don't remember modifying anything, did a system restore and started in safe mode - same thing. The only thing that may have changed was Chrome downloaded something - a new version? - without my knowledge. However, the system restore did not reverse whatever they may have done. I'd hate to sssswitch to Chrome every time I need to open a VR link...

Any thoughts? Thank you
