Firefox will not open .aspx files. I can open them with IE. What's up?

I updated Java, uninstalled and then re-installed Firefox. It will not open .aspx files. Internet explorer opens them just fine. .pdf files open fine also. Don't know?

How would I change the aspx to pdf? As far as going to the menu/applications, I don't see an aspx in the list? Sorry, but I'm pretty rank in this department. Maybe it is the website and not Firefox, although as stated, IE opens them fine.

Firefox will not open even with new profile

When I attempt to open Firefox nothing happens on screen. I have created a new profile still no joy. In the Windows Task Master Process window Firefox.exe is shown. I have attempted to update Firefox no joy I have uninstalled and reinstalled Firefox still no joy. I know that it is working in the background but where and how can I bring it to the foreground

Hi cor-el, and thanks
Have checked the Firewall that is ok and have allowed any mention of Firefox to have Internet acess , still no joy, I am using Zone Alarm.
I do not get any messages when I attempt open Fire Fox just the browser does not open. I can see in the Task Manager that Firefox has started and is sitting idle but no Browser window.
I End Task in the Task Manager before I attempt to start Fire Fox again after I have made any changes such as the changes to Zone Alarm as mentioned before. Then I attempt to start Firefox again and still no joy.

Firefox will not play Yahoo videos.I can play them on Safe version of Firefox. What is wrong?

I cannot play Yahoo videos on Firefox.
I can play Yahoo videos on Safe version of Firefox.
I can play videos on other sites (CNN,Fox,....etc.).
I recently updated to the latest version of Adobe Flash.

You were on the right track. However, It was the No-Script Extension that was causing the problem. I went to the No-Script Options then General tab and checked the box "Allow top-level sites by default".
I had noticed that as I kept trying to play the videos, a No-Script message popped up about something (don't remember exactly what it said).
The Yahoo videos now play.

Firefox will not open at all. Google Chrome main browser.

Google Chrome my main web browser with Comcast as home page.
Now Firefox will not open at all. What do I do. Delete Firefox and reinstall is what I think?

Yes, i would try reinstalling Firefox first.
A few other basic trouble shooting things you can try is this:
Run all Windows Updates, install all needed service packs, etc.
Update your graphics driver (Firefox uses your graphics card for some rendering, and an out of date graphics card driver can cause problems. [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Update all your plugins (Flash, Java, etc.): [http://www.mozilla.org/plugincheck/ http://www.mozilla.org/plugincheck/].
Download and Install MalwareBytes Anti-Malware, run a full Scan. [http://www.malwarebytes.org/ http://www.malwarebytes.org/]. This helps check that there are no viruses on your computer causing issues. You can uninstall this program after you clean off any infections.

What do I do to view images on CS5-64 when it will not open them?

The program will not open images, either directly or from Bridge. Using Win 7 on a Dell PC.

Strange, after rebooting, both Ph CS5 and Bridge are working again. Thanks for getting with me.

Since updating last time Firefox will not open new tabs unless I right click on a link. It won't open them via file or the tab at the top of the brwoser. Anyone know how to fix this?

Since updating last time Firefox will not open new tabs unless I right click on a link. It won't open them via file or the tab at the top of the brwoser or usinf ctrl + t. Anyone know how to fix this?

I can press ctrl for a new tab but otherwise a new tab does not open. I actually need help regarding this new Synch which apparently will be in Firefox automatically in an upcoming version so I am asking how that will synch with people who use LastPass-of course because I use this very successfully and really am not eager to change the set up that I have in place at this time.
I have read through endless FAQ trying to find anyone else who has this question or concern but have found nothing. Can you please tell me how that service will get along with LastPass which does basically the same thing as Synch-it is probably spelled wrong as it looks wrong to me but if I click back to where this issue began, I will lose all of this question so please respond for the upcoming service synch.

Firefox will not open, try to reinstall and message states firefox must be closed before install can begin.

firefox will not open. when i try to reinstall firefox the process stops. the message tells me to close firefox before i can proceed. but firefox is not running.

Prez,
I too have had this problem a few times with several different versions of FF.
What you need to do is to open a window to Task Manager (Ctrl-Alt-Del) and on the 'Processes' tab look down the list for Firefox, highlight the entry, then click "End Process". Accept the warning that pops up. You should then be able to uninstall.

Firefox will not open after attempting to upgrade to v5, sys restore didn't help

Was running 3.6 with no problems, but trying to upgrade today apparently broke it. The upgrade failed for some reason (the old .exe is still the only one in the Firefox folder & I can't find any files newer than April 2010 in there), but no matter how I try to run it, nothing happens - Firefox will not open, period. I tried reverting to last week with sys restore, scanning for malware with Malwarebytes, but still nothing happens. I'm using WinXP 5.1 media edition SP2 (yes, it's been around a few years but it works for me). I'm now using Chrome which seems to run just fine, tho I miss all my plugins.

Hi lwhealon
try from Start > Run > and type to check 1 of :
firefox -safe-mode
"C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode '''or'''
"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -safe-mode
(to enable the Run box in win 7 see: [http://blogs.msdn.com/b/tims/archive/2006/09/18/windows-vista-secret-3-bringing-back-start-run.aspx enable Run box win 7] )
also check if [http://kb.mozillazine.org/Firewalls Firewall] or/and other security software blocking firefox start (like ad-blocker, web-accelerator etc).
[http://kb.mozillazine.org/Kill_application With Firefox completely closed] (probably because you can not start it), open the [http://kb.mozillazine.org/Installation_directory application folder] (by default, C:\Program Files\Mozilla Firefox on Windows) rename firefox.exe to firefox1.exe, then double-click firefox1.exe. If Firefox runs without problems, it could indicate that your firewall is blocking Firefox.
good luck

Firefox will not open to home page as directed in options and settings. Opening in safe mode makes no difference, either. Any ideas?

Firefox will not open to home page as set in the settings. Even in safe mode, it still will not open to home page as directed. It seems to want to open to last set of tabs, even though that is not the way it was set in settings. It seems as though the settings do not have any impact on the way it behaves!!!

Create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.

Do a clean reinstall and delete the Firefox program folder before reinstalling a fresh copy of Firefox.

Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

Firefox will not open on my computer

From sometime last night to today (11/18) Firefox will not open when I click on the shortcut link from my desktop. I've tried to add another profile by clicking on start/run/firefox.exe but that doesn't even work. What would be the next step?

Do any error messages display when attempting to open Firefox? 
In the task manager, is the <code>firefox.exe</code> process running?
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:

Firefox will not open...please help.

My Mozilla Firefox will not open any windows, although it does start and show as running in my task manager. I have uninstalled and reinstalled it twice now and restarted my computer twice.
I CANNOT start Firefox in safe mode by holding down shift or using the "firefox/safe" in the run box.
I've tried it with applications closed, and open....I've tried it online and offline, I tried to run it in compatibility mode, I checked my computer for viruses...nothing helps.
I have read every troubleshooting item here but they only say try safe mode, or do something from Firefox when it is open such as reset it. I have no add-ons or extensions on Firefox and it just worked yesterday...also my computer is brand new Windows 8.1 12GB ram 2TB harddrive and everything else works fine.
please help

The firefox will not open new windows

My firefox will not open new windows. It opens new tabs. The problem is in the windows.

Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do not click the Reset button on the Safe mode start window or otherwise make changes.
*https://support.mozilla.org/kb/Safe+Mode
If it does work in Firefox Safe-mode then disable all extensions (Tools > Add-ons > Extensions) and then try to find which is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

I upgraded from 3.6.13 to Beta 4.0 and now Firefox will not open at all I tried to uninstall to start again but it will not uninstall either it does nothing.

I uninstalled Beta 4 and re-installed 3.6.13 now Firefox will not open at all I tried to uninstall to start again but it will not uninstall either it does nothing, I have been using Firefox for a long time but cannot resolve this problem can anyone help and give me a solution please. As I use Firefox as my web browser it is very frustrating.
The fact it will not uninstall appears to be something completely new as nobody I know who uses Firefox has ever encountered this in the past.

Did you check your security software (firewall)?
A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.

I have no navigation bar and firefox will not open in safe mode to reset to default config. Reinstalling doesn't work. Any help please.

I have no navigation bar ever since I closed it to gain more space on the screen. It won't re-open. Firefox will not open in safe mode, but opens immediately in normal mode with the new improper config, so I cannot reset to default config. I erased Firefox and re-installed and it still opens with the same faulty config. Why does Firefox not give me the safe mode dialog box, why can I not re-open the nav bar, and how can I do these two things, please? Firefox is currently unusable for me without a nav bar and without access to the default settings in safe mode. I cannot research the extensions I'm running since I have no nav bar to go to Tools, Add-ons, Extensions.
