Firefox and Thunderbird installed, but not in usual place
I have restored my Windows 10 Home (64), deleting all previous installed apps during the process. Hereafter Firefox and Thunderbird are downloaded and installed.
I did not find the 2 Apps in the usual program folder, and they do not appear in START->ALL APPS.
Searching my computer, I found Firefox and Thunderbird in these locations: Firefox: C:\Program Files\WindowsApps\Mozilla.Firefox_121.0.1.0_x64__n80bbvh6b1yt2\VFS\ProgramFiles\Firefox Package Root Thunderbird: "C:\Program Files\WindowsApps\MozillaThunderbird.MZLA_115.6.0.0_x64__h5892qc0xkpca\VFS\ProgramFiles\MZLA Package Root\thunderbird.exe"
My question: is this the usual place or have I mixed things up during installation ?
