Not hard to land in a tab with Firefox complaining that it doesn't know of an FTP handler. Google Scholar returns results to papers hosted on FTP all the time.

Not hard to land in a tab with Firefox complaining that it doesn't know of an FTP handler. Google Scholar returns results to papers hosted on FTP all the time. On the other hand, as annoying as this is, this is the one time that maintenance overhead actually makes sense to justify removal (out of all the times Mozilla has invoked that excuse), given how nonstandard FTP is and how kludgy the implementation has to be.
