Firefox Portable

Hey
Sorry if this is a repost.
What's the best way to register a portable app lets say Firefox on Windows 11 as a Standard browser?

Update: When making FF as a Standard browser in the app itself I am able to add it in the win 11 standard apps panel.
Unfortunately it opens now with the clean default FF profile. Any solutions for that?

Hello,
I am using Firefox Portable version on my desktop computer. I want to copy the "FirefoxPortable" folder (extracted from the installer) to either another location on the same computer or another computer or usb drive.

And which files are not needed for normal run?
eg.? Data\profile\datareporting\archived

The last known working version is 117.0.x...

Hopefully there's a work around, otherwise I will revert back to 117.

I've just tried out Firefox 115.4.0 legacy...When I try to start it on my Win 7 system, I get an error message stating 'Firefox 116 and later require Win 10.....run Firefox legacy 115 instead'

When I press yes, it produces the same message.
I have had to go into the Firefox64 directory to start Firefox from where it starts normally.

Also, I have downloaded the legacy and the ESR version of Firefox, As I'm using the legacy version, do I need the ESR version?

Thanks.

Hello:

When I click on Help and then About Firefox I see the message 'Checking for updates' and then I get 'Failed to check for updates'

I have manually installed FF 115.3.1 and know 115.4.0 is available. Using Win10 and FireFox is on a portable USB stick

Here are the Enterprise Policies.

FF Portable 115.4.0esr (but also going back to at least 115.x.x if not older versions) Win7SP1 x64

For various purposes, I used to drag 'n drop shortcuts from FF URL bar, into folders. That stopped working after a FF update. Researching it, I found it worked again by launching FF portable with -no-deelevate on the shortcut to it.

For years I've been running multiple instances of Firefox portable with no problem. As of version 119.0, I've run into an odd situation... if any other instance (BTW all instances are the same portable version) is launched after the primary instance (the one I always have running) it just opens another window of the same primary instance. Which is obviously a problem because the primary instance is the one always running. However, if I launch one of my secondary Firefox portables first (ones I only use ocassionally), then my primary one will launch as it should.

I got an error upon upgrading from 115.0.3.1 to FirefoxPortableESR_115.4.0_English.paf.exe on windows 8.1. "Firefox 116 and later requires Windows 10 or later. Would you like to run Firefox Legacy 115 instead?" answering yes launches 115.0.2.

I'm running Win7 with FF ESR 115.3.1 portable and wondering what's the difference between that and FF Legacy 115.x?

Thanks, John.
