Firefox Portable

I realized that the Firefox, Thunderbird, and SeaMonkey Portable launchers aren't fully portablizing paths within prefs.js. They portablize the drive letter, so you're good if you use it on an external drive or locally. But they were never updated to portablize partial paths so they'll work properly from a synced cloud folder between PCs or if you move the PortableApps directory.

I logged into Kucoin (Crypto exchange) through firefox portable.

In 3 minutes all my funds were transformed into BTC and transferred to another account.

I lost all my funds.
Afterwards I saw that when I logged-in, in parallel another instance logged in in China (time UTC+8).

Pay attention. The software is not safe to be used.
I will ask "PortableApps.com" to respond about this unacceptable issue.

Almost every time it starts it's asking to restore previous session even though my option is set on starting with new tab. Changed 1 to 0 in about:config as someone suggested - same thing...Aside from general slow start-up, works fine otherwise and closes without warnings or errors. I shut off power to the PC daily. Any ideas?

Nearly a year ago I installed FirefoxPortable on PC1 in some directory on disk E:. Now I copied it to PC2 to some directory on the C drive. Firefox on PC2 didn't recognize existing profile folder, let's call it 'ProfileNew', instead it automatically created new folder 'profile' in 'Data' directory. I ran 'about:support' and saw that in 'profile folder'.

Been using Firefox portable just fine for months, but now my Bookmarks bar is gone and I see this:

"The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem."

A long time ago, I moved PortableApps.com and FirefoxPortable to my D drive. I did this because I also had OBSPortable installed and I could not get OBSPortable pinned to the taskbar from the USB Drive. Once I moved FirefoxPortable and OBSPortable to the D Drive, both would pin no problem. But this week, I uninstalled OBSPortable. I'm just using FIrefoxPortable now. And I want to install OpenOfficePortable too. I'd like to move both of these to my USB Drive, but I'm running into a problem where FirefoxPortable won't pin to the Taskbar from the USB Drive. Any idea why?

Sorry, i speak Englisch only little.
Update from 94 to 95. Avast told Win32.Evo-Gen[Susp]

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.?

FireFox portable still writes data in %ProgramData%\Mozilla relating to the updater...
