Personally I tend to avoid running untrustworthy programs outside of a sandbox or VM.

what does that mean? are you not running any programs at all? you cannot know just by looking at the name if a program reads such sensitive info. and its not unlikely that some developer figured it would be a good idea to include it in automatic crash reports

yes, this is sensitive information. its like your fingerprint, you cannot change it. I think its quite obvious. web browsers firefox is fighting to hide more and more that even indirectly could lead to identification. websites can’t read this ID, this is just a comparison.
