Firefox Portable

I need to edit firefox registry keys to make some changes but I can't figure out from the docs where they are actually located. They say they are there but they don't where they are located.

I found something called FirefoxPortableSettings.ini but there is no key section.

Thanks.

I used this program to make my FirefoxPortable2ndProfile as my default browser : https://www.winhelponline.com/blog/register-firefox-portable-with-defaul...

But now when I open an an external link from another program I always see "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

I don't start with -no-remote and don't have MOZ_NO_REMOTE in Environment Variables either.

Since version 80.x Firefox Portable is not able to display some atlassain.net pages, e.g. login page to https://teleconnect.atlassian.net (no public page, but login screen should appear).
It regards to newer pages of atlassain.net, older pages seem to work correctly.
The Firefox 80.x installed version (Win10) -not the portable one- does not have this problem.
Any idea?
Thank you

Ok, so please someone tell me I can open a large fraction of my around a hundred tabs instead of opening each one individually with the extremely marginal FF sync?

The new version broke too many of my extensions in a way that made it super unstable and unusable?

One of the reasons I like Firefox Portable over regular Firefox is that it allows me to restore my previous session, where lots of information and tabs that I am using, with it's passwords and all that, are already loaded.

The problem I am having is that sometimes, when I have to exit and load FF portable again I get the message that there was a problem and need to reload. An the problem is just there: when I reload all my previous sessions and all its data disappeared.

Firefox portable 68.10 ESR is available to download on here but not Firefox ESR 68.11 and ESR 68.12.
Is there a different link to download those two versions?

I've been using Firefox Portable 65 for awhile and just went to Firefox Portable 72. It works perfectly except I can't seem to open links in 72 - it still wants to use Portable 65. I have tried changing the fle associations to 72 and it still opens 65. They are in two separate folders. I don't want to use 65 but I don't want to totally delete it. How can I unregister it for urls and html and so on and have 72 open them instead? Firefox defaults are grayed out in Windows (7) default programs and are all on my old Firefox 56 (desktop type) that I use from time to time.

If I use Firefox portable on mobile.de I see no pics. This I got on an update. Now I try to use the old Version. I have found an old copy
that I am using on C:\FirefoxPortable\. To get no Update message I have created a fiele policies.json and saved it in the folder
C:\FirefoxPortable\App\distribution
the contend is:
{
"policies": {
"AppAutoUpdate": false
}
}
This works, I do not get a Update message.

I removed gtk3 from my distro and Firefox portable would still run/work....

However The Tor browser which is also portable does not run without gtk3 and it is based on Firefox ...

what is going on here ?

I run a dual boot system - Ubuntu and Win10. Most of my time is spent in Ubuntu so my skills for transferring FF profile data into portable FF are a bit rusty.

Today I made new FF portable app "installations" on the Win10 system. I copied active profiles from the Ubuntu system and pasted them into the Win10 FF portable apps folders.
