Firefox Portable

i have many different firefoxportable in different folders. but recently this keeps happening whereby launching a 2nd firefoxportable will launch the 1st instance and thus a blank new window of the 1st instance instead of the 2nd instance.

Closing the 1st instance will resolve this but this shouldn't be happening. why is the 1st instance interfering with the launch of the 2nd instance?

these are the settings in all of my firefoxportable dirs:

When I copied FF 85.0.2 to another computer, it lost its settings AND its add-ons. I had to do them all over again.

Assuming it was keeping them in Windows 7, I searched C: for Firefox. I got these on the source computer but they could be from past Portable Firefoxes:

C:\Program Data\Mozilla
C:\Users\MyName\AppData\Local\Mozilla
C:\Users\MyName\AppData\Roaming\Mozilla

The target computer isn't available right now.

Of course everything is supposed to stay in the Portable Firefox folder, so it's pretty serious.

Thanks.

Just updated to 86.0 but Firefox Portable 86.0 does not ask to save logins, whereas 85.0.2 did beauryfully. What happened? Cannot find anything on the Mozilla's pages. Any tips to solve this?

This is a brand new laptop with great specs. The vast majority of my programs are on my older laptop, and I only use this new laptop for the bare essentials. So no chances of viruses, etc. I only have simple programs like Notepad++. So it seems too often, most of the time, just opening a new tab in Firefox Portable will cause the browser to not respond. And then normally one could move the mouse cursor around and go to another window or go to Task Manager and force quit the Firefox Portable exe.

[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
