Firefox Portable

In the latest Firefox (regular) and FF ESR the updating options have been changed. Now the only "option" is "automatically install updates". If you try to tick the other option "check for updates but let you choose to install them" this warning box pops up "Firefox encountered an error and didn’t save this change. Note that setting this update preference requires permission to write to the file below. You or a system administrator may be able resolve the error by granting the Users group full control to this file.

Could not write to file: {$path}"

Can't find an answer but maybe I use the wrong search terms in which case I beg your pardon and ask for links.

Hi all, had a quick look around support forums / Google / DDG but can't seem to find others having a similar problem.

I'm using the latest portable versionof Firefox (83). Under Help > About Firefox, it identifies itself as Firefox 83.0 (64-bit). However when I log onto Shopify, they identify my browser as Firefox 78 and recommend an update. I then check some of those 'What's my browser?' websites which also identify it as FIrefox 78. They however also incorrectly identify my OS as Windows 10 when it's 7, so go figure.

I just got the FirefoxPortableESR_78.5.0_English.paf.exe file and the PortableApps.com files and installed on my ancient Sony laptop that is running Windows XP (last updated edition). The PortableApps installs well and shows me the FireFox app inside the list. I run it (both as user and as administrator) , it puts up the Firefox splash screen then exits with no error message. I have asked that errors go to the "log file" but I cannot find the location of the log file.

Is there some magic setting to get it to run on WindowsXP?

It looks like the way Firefox handles its AppID changed recently which broke taskbar pinning with the PA.c Platform. I've put together an updated Firefox Portable launcher that will properly allow existing and new pins to work again. It's a zip file with an updated launcher and the necessary code.

Please let me know how it works for you.

In order to make the menus wider I tried to setup a suitable userChrome.css file.

According to some suggestions I put an empty userChrome.css file into (new) folder

<PortableAppsFirefoxfolder>/Data/profile/chrome/

and put the following statments in there


.bookmark-item[container] .menu-iconic-text {
max-width: 600px !important;
width: 600px !important;
}
* { background-color: orange !important; }


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.
