[Fixed] Firefox Portable gets an error when turning off automatic updates

Same issue here
Paul vP

I can confirm the issue. And I've determined that it's due to the custom AppID. Turns out Firefox uses it in multiple ways. For background, Firefox and Thunderbird changed the way their AppID works and broke taskbar pinning. To fix it, I added it back the way it was but this broke Thunderbird itself so Thunderbird Portable uses a simplified one (ThunderbirdPortable). Firefox only encounters this error when trying to write to the update settings json file (which it can't write to because the AppID contains backslashes).

To fully fix this, I'll need to push an update out to Firefox, Thunderbird, and the Platform to properly handle it all and preserve the ability to disable updates. I'll continue working on it tomorrow.

As per user goveto (and confirmed by me) it also causes: "I just updated Firefox Developer Portable to 85.0 Beta 1, and I'm having the following issues in the address bar.

1. When you click Page Actions (3 horizontal dots), the pop-up shows an empty box.
2. Bookmark this page star button is missing."

I've compiled an updated launcher (FirefoxPortable.exe). The launcher, code, and GPL are included in this zip:

https://portableapps.com/downloads/temp/FirefoxPortableTaskbarPinFix-202...

This should fix the issue with being unable to set update preferences as well as the issues with Dev/Beta having the three dots menu fail. Please test it out and let me know if this works for you.

Note that the AppID for Firefox Portable will be changing so this won't work with your existing taskbar pins and the pin will change once the official release is out.

This should be fixed in Firefox Portable 84.0.1. Please report back and I'll start pushing this out to all channels.

This is also fixed in ESR 78.6.0 Rev 2

This is now fixed in all channels with the release of Test 85 Beta 4, Development 85 Beta 4, and Nightly 86 Rev 2.

I am not using the same version, so I do not know about this problem.
But, I do not want it to be updated itself automatically also.

So, I use "search" on the "App" folder, to find out some files then modify them.

1. Renamed the "updater.exe(there are two of it)", "updater.ini(there are two of it)",
"update-settings.ini(there are two of it)" and "update-config.json" by adding ".jpg"
after the end of the extension letters.
For example: rename "updater.exe" into "updater.exe.jpg",
rename "updater.ini" into :"updater.ini.jpg".

2. After that, open "channel-prefs.js" by notepad, and edit the last
sentence into " pref("app.update.channel", "default"); "
(There are totally two "channel-prefs.js" , we must edit both of them.)

3. After I had done the above, the portable Firefox cannot update itself forever.

Thank you.
