Firefox Portable

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.

Hello,
I regularly use Firefox Portable (currently v. 89) and I am confronted with this issue.

If I quit Firefox Portable normally and restart it, it loads in a decent amount of time (maybe 10 seconds before it loads a page). Same behaviour on the desktop version of Firefox, by the way. Likewise if I close my session but don't turn off my computer.

User has successfully used a third-party tool to register FF portable as the default browser in Windows.

User wants to be able to retain this setting while launching other instances (different versions) of FF portable.

When AllowMultipleInstances=true is set in .ini, the default browser setting no longer works correctly. For example, clicks to hyperlinks in the system or via other apps will now open the wrong FF instead of the default instance.

About FF v89 that it was a major UI change, a major cock-up IMHO.
For the past few years, after the last UI change and it was working well up to v.88 I was using Aris' userChrome.css tweak to keep my tabs below
the address bar {no Bookmarks bar, turned off in the drop-down} from over at GitHub.
Now v89 has destroyed it and over at mozzillazine guys like me are scrambling to try to find ways of fixing it.
It seems that the silent majority, me included, like our tabs on the bottom and Mozilla themselves is not listening.

I get a white screen with a thick blue bar at the top and nothing else. It just sits there unless I manually go into the Task Manager and kill it. This started with FF 90 beta. Previous versions updated fine.

PS: I always use the PortableApps built-in updater to update.

Hello to all!
I used many years version 2.0.6.0 of executable file FirefoxPortable.exe and all was good, but i have a problem with extensions(plugins), every time when i prepared my build with all extensions and copying in another place i need again INSTALLING ALL EXTENSIONS.
This thing very boring for me and i need to be updated for the new build of the FirefoxPortable.exe 2.3.0.0 and problem with extensions solved.
I was been very Happy

I'm trying to update Firefox portable and get the message "Extract: error writing to file omni.ja"

I've tried using the regular updater as well as downloading the installer package and am getting the same error message.

Any help appreciated.
