Firefox creates local profile adding to portable

Submitted by SomebodyToLove on December 8, 2021 - 8:15am

Windows x64, Firefox 78.15, copied on local system disk
I have quite strange situation: when I run Firefox from shortcut, it uses profile from ...\FirefoxPortableESR\Data\profile as expected, but when I press a link from email, it switches to %APPDATA%\Roaming\Mozilla\Firefox\profile which is definitely not what I want. Moreover, I see all that bunch of mozilla folders in %PROGRAMDATA%, %APPDATA%\Local, %APPDATA%\LocalLow and %APPDATA%\Roaming. So what's wrong with me/Mozilla/outer space etc.?

PortableApps.com Platform is not updating Firefox Portable on one computer.

I have two laptops.

Acer Aspire 5, which is really old.

Acer Nitro, which is an entry level gaming laptop.

If you remember, many months ago, I was having some issues with Firefox Portable. I forgot what they were. But I did a clean install and started over and did everything right that time. So there shouldn't be any issues.

So anyway, I've been getting a lot of update alerts from the browsers on both computers and have been constantly launching PortableApps.com Platform to update the browser.

Two versions of Firefox

First post, newbie.
I have Firefox ESR 52 installed on my desktop (for old school reasons, eg Classic Theme Restorer), and would like to try latest Firefox Portable ESR. I would install it to the same 8 GB flashdrive that has my mail client: Thunderbird Portable Legacy 3.1 (great little program, clean functional interface, never any issues). There's over 7 GB of free space on this flashdrive.
Couple of concerns:
Any way to set Firefox Portable to be the default browser which launches when I click on a link in an email in Thunderbird Portable?

[Fixed] Firefox Portable sometimes doesn't load addons

Like the title says. I only use Tabliss, Dark Reader and uBlock Origin. These never gave me problems until recently when I updated Firefox Portable to 92.0.1 or somesuch, and, updating to 93 after that didn't make the problem go away. If I close Firefox Portable and open again right away, the addons load normally. The issue could be related to Sandboxie-Plus, as it always occurs after I emptied the sandbox, but it also happens sometimes (sometimes frequently) if I run Firefox Portable unsandboxed.

[Closed] Firefox Portable 93.0 "Another instance of Firefox is already running."

With the AllowMultipleInstances=true in FirefoxPortable.ini (that's in my C:\FirefoxPortable folder along with the FirefoxPortable.exe file) when I try to open a 2nd instance it gives the same error popup dialog again that I also got a few months ago when I was still on a (slightly) earlier version of Firefox Portable, and that used to be fixed in an updated version until it came back as of 93.0.
