Package: iceweasel Version: 38.2.1esr-1 Severity: important
Hi. It seems Iceweasel keeps files that have been e.g. uploaded to some website (e.g. Google+) open for arbitary times (sometimes they're closed fast sometimes I waited 20 mins and nothing has happened). The effect is e.g. that one cannot unmount filesystems on which those files are. After killing Iceweasel, the files are of course closed and unmounting works again. Cheers, Chris.
