Firefox Portable

Hi, I feel like a fish out of water here, surrounded on all sides by what is essentially a windows-centric site..I am a dyed in the wool user of that other OS.. Linux, ( Ubuntu).. I am here basically out of sheer frustration..There are so many iterations of portable apps for Windows and yet Linux is lacking.
In particular I have spent days searching for a portable version of Firefox that will run exclusively from a USB..
I have an Appimage of Firefox that runs , mostly from a USB, but it still insists in writing to folders in the home directory on a PC..

I am currently running Firefox Portable 93.0 on Windows 10 Pro x64. For a while now (earlier versions of Firefox Portable) until now I cannot print anything from the browser. All other browsers on my system (Chrome, Edge, Brave) and regular applications print fine. I have combed the internet searching for help but not finding my specific problem. I have repeatedly stopped and started the Spooler service with no luck. Doesn't matter what content I'm trying to print, either. I would very much appreciate some help. Thanks much!

Hi. Can I launch an instance with the specified profile? The "-p" switch doesn't work.

Hi,

I was hoping that 78.14.0esr was released but instead, the new version is firefox 91.1.0esr.

Is there any plan to release 78.14.0esr?

I was using esr because I hate the new interface and the delete of the "vie image" option. So I won't use the 91.1.0esr.

Thanks in advance

Like the title says, and when I restore Win 7 from an image, FF won't start the first time. I think it balks at there being old stuff in its C: drive stashes.
FF is on my computer's E: drive.
I'm afraid to use it on somebody's computer, especially if they have FF too.

Hi,

I had to rename firefox.exe so:
- firefox.exe renamed to firefoxP.exe (for both x32, x64 arc)
- firefox.exe.sig renamed to firefoxP.exe,sig (for both x32, x64 arc) (I DO NOT KNOW IF THIS IS REQUIRED)
- FirefoxPortable.ini copied next to FirefoxPortable.exe
- FirefoxPortable.ini Key "FirefoxExecutable=firefox.exe" changed to "FirefoxExecutable=firefoxP.exe"
All working OK

Buenos días.

Desde que Firefox Portable se me actualizó hace pocos días a la versión 90.0 han dejado de funcionarme las páginas de Gmail, Google Calendar y Contactos de Google. Accedo pero no me cargan, por más que actualizo, o no me funcionan, todas las opciones, especialmente el acceso a las aplicaciones de Google o a la cuenta de Google. Sí puedo, por ejemplo, leer los correos. La barra de la izquierda de Gmail, de etiquetas y Reunión, tampoco me funciona...

Trying to install add-ons, I get "An unexpected error occurred during installation."

The Firefox is portable and I was able to install add-ons in the past.

Hi all, I'm new here, but I used firefox portable since months ago...

In our company, we use a frozen version of firefox to maintain java and flash.
I've been testing portable firefox (same version, ESR 52.9) for a while, and found one problem when, inside portable firefox, I try to open and eml file...

It's say that Thunderbird is already open, I must close it before open this attachment. Same message when trying to open a second instance of portable Firefox (but this is not the problem). Thunderbird in our computers, is not portable.
