I use a program called SUMo from kcsoftwares.com to keep my programs up to date. I notice with Firefox Portable, SUMo checks what is the current version of FirefoxPortable.exe that is in the FireFoxPortable folder. However, if you use the Help>About menu from within Firefox Portable to update, FireFox Portable does update itself ok but does not update FirefoxPortable.exe, meaning that SUMo still thinks that Firefox needs updated.
If I download the installer from portableapps.com, then the installer does update FirefoxPortable.exe, but it is easier to update from within Firefox Portable.
Should FirefoxPortable.exe not also be updated, when using Firefox Portable to update?
Should I post on kcsoftwares.com and ask them if SUMo can check instead what version is in the folder FirefoxPortable>App>Firefox64>firefox.exe, as that would show the correct updated version?
