When I download a file, Firefox removes the file extension. I mean, if I download "something.pdf", it saves the file as "something". I didn't have this problem before yesterday.

Any help would be appreciated...

Edit: But I can open them by right click and open with. Only problem is the file name. I barely used my home pc in last two days and I'm really curious about what happened. I tried to reset everything revelant to downloading and file extensions in "about:config". But no difference...

Did you check that the folder you're saving the file into is not configured to hide file extensions? –  Justin Pearce Dec 28 '12 at 19:24

your files extensions removed or just not shown?? –  Christopher Dec 28 '12 at 19:32

@JustinPearce: Good question, although that option is not folder-specific. –  Karan Dec 28 '12 at 19:43

if you double click the file and it opens correctly, then "Hide Extensions" is enabled. –  Chris Nava Dec 28 '12 at 19:50
    
Of course they're removed. And when I rename them and add the file extension, they open correctly... –  s.alem Dec 28 '12 at 20:03

The most radical solution and worked. Thanks a lot. But I wish I could know why that happened... –  s.alem Jan 1 '13 at 0:06

Not enough rep to post a comment, apologies. It might not have to do with you or your browser. The website might have just posted an update that now forgets to put the extension on the item. This happens a lot more then people realize with bad testing or no testing. Can you replicate the issue on another computer. If you can replicate it on another computer, I would send a note to the owner of the site.

It's not about the website, because i've already tried differents websites. I can't replicate the problem, because I have no idea what's wrong... –  s.alem Dec 28 '12 at 22:22
