I am currently use Firefox V3.6.13. And set it up for auto-upgrade. However the recent upgrade to V3.6.13 gives me some headache. All PDF downl= oads=20 will be saved without the ".pdf" as the file extension (all old version wor= ked=20 just fine), which makes my computer doesn't recognize the pdf files. I can manually rename the file to a *.pdf, but with tens~hundreds pdf files= =20 downloading/day, this bug is really annoy. Anyone got a clue on how to fix = it?=20 After this issue is fixed, I am going to turn off the auto-upgrade feature = since=20 every new Firefox hot-patch introduce more bugs. Funny N.
