Firefox Portable - mailto Path Adjustment Not Working

Hello,

I found an issue with Firefox, Portable Edition regarding portable application associations.

According to your documentation:

> "The path will be adjusted automatically as you move PCs."

I configured mailto to use ThunderbirdPortable.exe (using Use other... and selecting the launcher, not thunderbird.exe) exactly as described in the documentation.

However, after going to another PC (or even changing the drive letter), the stored application path is not adjusted automatically. The mailto association no longer works until I manually browse and select ThunderbirdPortable.exe again.

This appears to be inconsistent with the documentation, which states that the path should be updated automatically when moving PCs.

Could you please verify whether this is a bug or if there is an additional step required? If it is a bug, I would appreciate it if it could be fixed in a future release, as portable application associations are an important part of the portable experience.

Thank you for your time and for maintaining Firefox Portable.
