Firefox Portable

This issue only occurred on one of my two computers where Firefox Portable is installed, so I'm assuming it was a fluke file corruption or the like. But here is the full popup message:

Hello,

I am looking for a way to get rid of the following popup:

"Firefox can be updated to a newer version"

I have deactivated the auto updates and possibillity to update in general as i've seen in other posts.
But i can't find the proper setting for this not to show up.

Hello
I am new to PortableApps, I am looking to create a portable app for Firefox (or chrome) that I can use with a website that uses Flash. How do a created that it doesn't prompt for the flash player every time. I am also looking to be able to copy this to multiple computers.

Thanks for the help.

Windows 10 Pro 1909

I need to be able to run it (or another portable browser) and "regular" Firefox at the same time.

Hi all - being fairly new to this Forum, I'm hoping you more experienced users will be able to help & advise me.

I had Firefox Portable ver 78 working just fine, on my 64 bit PC. When I run the Firefox78.exe from the installed folder it opens in 64 bit perfectly. But if I click on a link in an email (after checking it's safe!) or in a file of saved website links, Firefox opens in 32 bit minus all my add-ons. I don't want to run 32 bit, only the 64 bit version, but how can I force Firefox to always open in 64 when I click on hyperlinks?

Why the option "Refresh firefox" does not work in portable version? https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-s...

Any help?

thanx

I need to edit firefox registry keys to make some changes but I can't figure out from the docs where they are actually located. They say they are there but they don't where they are located.

I found something called FirefoxPortableSettings.ini but there is no key section.

Thanks.

I used this program to make my FirefoxPortable2ndProfile as my default browser : https://www.winhelponline.com/blog/register-firefox-portable-with-defaul...

But now when I open an an external link from another program I always see "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

I don't start with -no-remote and don't have MOZ_NO_REMOTE in Environment Variables either.

Since version 80.x Firefox Portable is not able to display some atlassain.net pages, e.g. login page to https://teleconnect.atlassian.net (no public page, but login screen should appear).
It regards to newer pages of atlassain.net, older pages seem to work correctly.
The Firefox 80.x installed version (Win10) -not the portable one- does not have this problem.
Any idea?
Thank you
