- Install Portable Firefox
- Customize it with stuff
- Update using original Portable installer
- Discover that your customizations were wiped
The problem is, from what I understand, that the installer will wipe the App\Firefox and App\Firefox64 folders. But a lot of customizations rely on additional files located in these folders.
Right now, to update Portable Firefox, I resort to installing a new version into a fresh folder, then copying its contents over my original installation. That way my customizations are preserved.
