Firefox Portable

[Issue] Using the "set as desktop background" feature I noticed that the "Desktop Background.bmp" is stored in the AppData \Mozilla\Firefox\ folder actually the FirefoxPortable new image is also overwriting the Firefox resident setting.
There is any workaround to avoid this issue ?

I am on a work computer and when I go to Help and About Firefox, I cannot check for updates. It says Updates disabled by your system administrator. Why does this happen in the portable version?

Also I cannot put the PortableApps.com Platform on my PC since it is blocked by our IT department so the method above was the only way to quickly check for Firefox updates.

On my old laptop, I installed Portable.apps Platformer to "C:\Programs\Portable Apps". I then used it to install Firefox Portable and was able to successfully pin it to the Taskbar, no problem.

On my new laptop, I can install Portable.apps Platformer to the same location "C:\Programs\Portable Apps" and be able to pin Firefox Portable to the Taskbar, no problem. But the thing is, I want to install it to my USB Drive instead which is "G:\".

Good afternoon,

(1) Background:
I have three portable Firefoxes working together.
Every month, I update the portable Firefoxes by deleted the old folders named "App"
and the old exe files named "FirefoxPortable.exe" , then download their new version
to replace them.

(2) Issue:
This time, the Firefoxes cannot MultipleInstances.
The "second opened Firefox" cannot launch itself.
When I open the second Firefox,
It just opens a "new Firefox windows" of the "first Firefox" instead.

Hi. For the last several months, I have been running Firefox Portable and Waterfox Portable at the same time. Then today, I experimented with Firefox Portable and Waterfox Full Installation at the same time. The problem is that both Waterfox browsers, Portable and Full Installation, are extremely weak browsers. There is a video cam website that I visit and if I just open one person's webcam it can freeze on occasion. If I have two webcams open, it freezes up a lot more. I can forget running my own webcam. But none of these problems exist in Firefox Portable

We are working with Firefox Portable ESR 78.6.0 on windows 10 OS
We want to write logs in a txt file. To do this, we used window.dump ("txt") in js files.
we have set the configurations from about:config :
"browser.dom.window.dump.enabled" to true and "browser.dom.window.dump.file" : "c:\file.txt". (we tried other locations)
the result is always : the file is created but it is still empty.
Is there another configuration to do or another way to redirect the console log output to a file?

Thank you.

I've always been able to check for updates manually in Firefox Portable. However, now when I go to Help and About Firefox, the program no longer checks for updates. It says Updates disabled by your system administrator.

Is there a way to fix this so I can check for updates again and continually updating the program?

Thanks!

I know there's been more than a few posts about multiple instances of FFP but I don't recall seeing one that was my specific question. Most involved different versions or an installed version and a portable version. I am wondering if it is possible to run multiple FFPs of the same version just from different folders. I have tried the AllowMultipleInstances=true parameter in the past but that just resulted in a link being clicked from outside FFP opening Firefox in a new window void of extensions and theme and all that. That isn't what I am after.

The installers for Firefox 84.0.1 in the languages Simplified Chinese and Turkish are corrupt / truncated on the server.
The Installers for other languages are all about 120 MB in size, but those two are 102 MB and 94 MB in size respectively and are failing their integrity check.

The hashes of the downloaded files are matching the listed hashes, but the files are corrupt, so, the problem is server side, not just a bad / incomplete download.
