Talk:L1® Model II Power Stand Firmware Updates
Just an FYI from a Mac user.
The first download of this 1.3 ".bos" for the powerstand I did with Firefox, and the Updater application did not recognize the format. I used Safari to re-download the file and it was then 'recognized'.
The various browsers can have a number of "default" actions which might take place after a download, as well as differences in how they browsers set the 'file type' for an "unknown" file name extension, so it's a little difficult to tell what was different without a lot of further testing ... but I have similar issues with downloading "geocaching" information (works flawless with one browser but not the other).
