Update to firefox 138.0.0.1856

Known issues:

• There is an unusual gap above the tab bar when enable menu bar.

Changing locale:

• In about:config Toggle extensions.langpacks.signatures.required to false
• Toggle xpinstall.signatures.required to false
• Toggle intl.multilingual.downloadEnabled to true
• Toggle intl.multilingual.enabled to true
• open the langpack for target locale (eg firefox-70.0a1.en-CA.langpack.xpi if you want an en-CA locale).
• In about:preferences click "Set Alternatives" under "Language", move desired locale to the top position, click OK, click "Apply And Restart"

I never said the browser would support Windows Vista. However, if you insist on running it on Vista:

• Set the environment variable MOZ_DISABLE_CONTENT_SANDBOX=1.
• If the installer or browser becomes unresponsive, run taskkill /f /im firefox.exe.
