Since updating to version 6.02, a non-fatal message appears when starting Firefox. Message is: "Using registry key: Software\AppDataLow\1fd1c56". Clicking "OK" results in Firefox loading. Frequent page redirects to random sites. No change after backing up profile with Mozbackup 1.51, uninstalling/reinstalling Firefox, then restoring profile from Mozbackup. Modest improvement after regedit deletion of registry key, but it reappears. Malwarebytes found and removed Win32:Adrotator, but problem persists.

I have used Mozilla for longer than INternet Explorer and think it's great. However, since installing Webroot Security Firefox has routinely started crashing. Not always in the same place or with certain sites, but randomly. I emailed Webroot who said it's not a problem they have encountered, but they issue reguar updates - blah blah. I usually use Norton which is fine, but we have so many PCs / Laptops at home it made sense to buy a bigger licence product.

Netflix support says I have to contact you, since my browser might be corrupted? I have uninstalled and reinstalled Firefox, same problem. I just get this same page, listing the system requirements, all of which I meet. I have Windows XP 64 service pack 2, and use Firefox 11. I tried to check my plug-ins, and tried to update Silverlight, but again got a message that I didn't meet system requirements. Very frustrating!! This is the message I constantly get: Instant Watching System Compatibility Complete System Requirements

To watch instantly, youll need a computer that meets the following minimum requirements:

   Windows
       Windows XP with Service Pack 2, Vista or Windows 7
       Internet Explorer 6.0 or higher; or Firefox 3 or higher; or Chrome 7 or higher
       1.2 GHz processor
       512 MB RAM
   Mac
       An Intel-based Mac with OS 10.4.11 or later
       Safari 3 or higher; or Firefox 3 or higher; or Chrome 10 or higher
       1 GB RAM
   Chrome OS
       A Google Chromebook with Chrome OS 13 or higher

I just installed Firefox 4 to replace version 3.6. I prefer to keep 'bookmarks bar' on no matter which version I am going to use. In Firefox 4, the stop/go/reload buttons have been combined into one button, and are attached to the right edge of the location bar. In its default setting, you can easily see the combined button. However, when I keep 'bookmarks bar' on bard and below the location bar, the combined button disappear. Why? Is there any way to keep both the combined button and 'bookmarks bar' on board?

I've given the basic information. My screen is messed up since I installed version 4. The location of the lines changes as I type, or as I change pages. And also areas get blocked out as I move the cursor.

Every once in awhile after closing Firefox 3.6.13 the process continues to run. The way I discover this is my CPU temperature monitor is increasing from 36C to 50C, so I open the Task Manger and see that it is using 50% of the CPU, slowing down the computer. I am running XP Professional 64 bit SP2 with all the latest updates on an Intel E8400 3.0GHz overclocked to 3.6GHz and 4GB dual channel DDR2-1066 at 800MHz. This happens only occasionally, maybe once or twice a month. I just end the task and the temperature of the CPU drops and everything is normal again.

I just built a new system, loaded all files and installed all need software, but one...Firefox. Came to the site, clicked to download the 3.6 version and I got a message saying "File Corrupt." I cannot install Firefox or even start the download of the installer for some reason. Then tried to disable my firewall, and still continued. I love firefox and would like to be able to continue use with this program...

There is a registry key that can be edited to have IE do this. Is there a way to have Firefox pop up a dialog box asking what I want to do with the PDF file? Here is the IE registry key: [HKEY_CLASSES_ROOT\AcroExch.Document.7]

  "EditFlags"=hex:00,00,00,00

I am using Firefox 4.0.1. I have checked the settings on my browser under Tools / Options / Tabs and "open new windows in tabs" is set. However, whenever I click on a link on a website, Firefox opens the link in a new window. This occurs even if I right click on the link and choose the option to open the link in a new tab instead of a new window.

This behavior began just recently. To the best of my knowledge, none of the add-ons have updated recently.

Firefox is not responding to scroll requests sent by my Lenovo USB optical mouse via the Scrollpoint. (FYI the Scrollpoint functions pretty much like the Trackpoint on a Thinkpad keyboard, giving it 360 degree scrolling much more fluidly than any wheel on an ordinary wheel mouse.) The Scrollpoint commands are recognized quite well in just about every other program I use, including word processors, email programs, and especially other browsers such as Opera. I have, in fact, switched to Opera as my main browser until this feature issue is resolved in Firefox. Thank you for your support.

When Firefox 4 (final) was released I tried it on Windows 7 and it worked fine. I decided to downgrade back to Windows XP 64 on the same machine and found Firefox would usually unexpectedly close roughly 5 to 10 seconds after launch, with no error message or crash report. If I open it several times it works fine eventually, as if it does not close after about 15 seconds it doesn't prematurely close at all.

MS Silverlight is apparently required to stream Netflix. Streaming has stopped working for me every since Firefox upgraded to 10. MS says Silverlight will only work with a 32 bit browser.

Firefox 4 installed on Win 2K3 R2 server OS fails to play radio streams that play just fine on the same machine using IE7. Server has just been rebuilt with fresh OS install and may need plugins? Popup player appears but produces no sound - animated buffering icon simply spins and spins and spins . . .
