• When I try to print, and the HTML document firefox downloads only a blank page.

  I sent some documents in pdf format. I chose to download, the download arrow fired to the blue. I was then able to select the file. Opening the page print the normal browser and I was able to print. I need to reprint pages and this is where my problem comes in. Now when I try to select the firefox file shows that it is downloaded the file but when I select the downloaded pdf firefox only to download the doc again and displays a blank page.

All my downloaded pdf files types changed html firefox for documents adobe acrobat documents. I can now print what I want. I know that technically it does not really solve the problem of firefox regardless of this issue, but this allowed me to print my docs and that's what really mattered to me. Thanks again for your help.

• Poster off-screen at the start of Firefox

  Hello. I'm having a problem with Firefox 8. I've updated just now. At first, everything seemed fine, but only today, when I opened Firefox to browse the Internet, never, it seems, although I heard him running. The window itself disappears whenever I tried to access Firefox, despite always on display in the preview window. In addition, whenever I clicked to open firefox, several windows appear to have opened to the start page of Mozilla. Despite this, none of them will appear on the desktop when enlarged. I tried to access Firefox via the Manager tasks, restart my computer several times, had tried to get Firefox in safe mode and even re-installed and uninstalled Firefox itself three separate times. I also tried to use Ctrl-Alt-Delete and Ctrl-Alt-space-M and these corrections that I met to try to resolve this problem, of which none has solved this problem Firefox is the main browser I use. It's frustrating for me that I can't access the browser. It seems to work, else the fact that I can't see what I'm trying to access something other than a miniature preview displayed when I hover over the icon on the desktop. Is anyone else having a similar problem, or is that what I'm doing wrong?

  I ran the antivirus scans on my computer, which is only a few months old and this doesn't seem to be a hardware problem. If anyone has any advice, solutions, or just the same problm, entry would be well appreciateed. I'm close to the end of my tether if it continues to be. I thank very you much for any help you may offer. I would be extremely grateful that I can't access my information for troubleshooting this issue due to the above question. I apologize for the inconvenience.

  Edit: Starting from 27/11/11, I tried also back to previous versions of this browser to see if that fixed this issue, all to nothing does not. I've uninstalled and reinstalled this browser several times, always with no end to the problem in sight. I decided to leave Firefox uninstalled for now, out of pure frustration with this issue. I really love Firefox, but it is of no use to me if I can't access the content I am trying to see. I hope this problem is solved in the future, because to switch browsers threw me for a bit of a loop. Thanks again for your time and consideration in this matter.

  Use Restore or expand in the context menu of the icon in the taskbar to set the focus to the Firefox application if you do not see it.
  
  Open the system menu via Alt + space and see if you can resize the window.
  If it works then close Firefox (file > exit/Quit) to save the setting.

• File download opens at the start of Firefox

  I just reinstalled Firefox on my Mac. Now everytime I open the program the .dmg file appears on my desktop and the dialog box where I needed to drag the firefox icon in my Applications folder appears. Firefox starts and works fine, but it's embarrassing to have these as two other pop up on my desktop as well. What should I do to get rid of these things?

  Make sure that Firefox is installed correctly.

  Open the Firefox disk image (DMG) file and drag the Firefox program in the folder of the application on your hard drive.
  
  You should not double-click the Firefox application to run from the disk image and drag it out of the DMG file instead.

• the free mozilla Firefox download

  I'm not able to download Mozilla Firefox on my computer. Since my browser Internet Explorer in Windows 8, I hit the free download button and he says 'Thank you for downloading' but the program does not start. I'll download and Firefox is not.

  Thank you, Fred. I appreciate your advice. Your comments on malware and how the download of Firefox should "do all the work", made me think that maybe I had a deeper problem. So as an experience, I tried to download Google Chrome and it's the same thing (Nothing!). So instead of throwing my computer in the trash, I tried REFRESHING it ("refresh your PC without affecting your files" read). The process took time, and I have to reload programs like Microsoft Office and my HP printer, but it FIXED THE PROBLEM! Hallelujah! Then I went back to this link that you sent me for Firefox and downloaded without problem. Thank YOU for helping me see that maybe there's a solution out there.

  Update: Firefox beta 34 disappeared completely from my computer. I finished the download version 33 and everything seems OK now. Still have no idea what happened past.
