Language Problems with automatic firefox updates

Last week, when I updated the company's portable version, I found that FF had changed to the English version.
"Firefox 3.5 XML parsing error: Undefined entity" occurs.

I got a Chinese patch.
However, after the upgrade at home on weekends, FF found that the upgrade was still in the Chinese version.
There is no XML parsing error.

In retrospect, it seems that the language prompted during the upgrade is different.
Tested, indeed:

This is a prompt for the company's portable version to automatically update

This is a prompt for automatic updates at home.

It seems that the configuration is automatically updated.

Update. ini found in firefoxportable3/APP/Firefox /.
There is a line in it

[Installation]
Locale = en-US

It is probably here.
Change

[Installation]
Locale = ZH-CN

Restart ff and update automatically again
Haha, the Chinese version is prompted!

Now the problem is solved!

PS:

Both the home and the company use a portable version.
I remember that although the portable version of the same FF version was under
However, the download source may be slightly different.
Resulting in later differences

For example, the screen at startup:

The company has always been

The home has changed
