Firefox won't open my default email program

I have imac desktop, OS X. Previously, FF would open my mac default mail, but now it will not. When I click on my link "check mail" it opens my "home page". Can you help

There is a fix for Dreamweaver, so it works in Firefox 3.6+ versions:

There is a $5.00 fee for that Dreamweaver fix. That website and the fix are not associated with Mozilla in any manner. Support for that fix is provided by that that website via email.

Firefox won't open links from other programs if already running

I've seen this reported many other places, but none of the solutions have worked. I am running Firefox v33.0.2 (current as of this message) on Windows 7 64-bit (fully updated). I did the following:
1. Completely deleted my profile;
2. Uninstalled Firefox, then manually deleted all remaining files on the system pertaining to Firefox and rebooted;
3. Gone into the Windows "Default Programs" control panel (DPCP) and told it to make Internet Explorer the default (giving it all of its defaults);
4. Downloaded a fresh copy of the installer and installed Firefox 33.0.2;
5. Let the installer set my default browser to Firefox;
6. Tested link opening behaviour (see below);
7. Let Firefox set itself as the default browser when it asked me;
8. Tested link opening behaviour again (see below);
9. With Firefox not running, gone back into the DPCP, and had it set all of Firefox's defaults;
10. Tested link opening behaviour again (see below);
11. With Firefox not running, set Internet Explorer to the default via the DPCP, then back to Firefox;
12. Tested link opening behaviour again (see below);
13. Repeated steps 11 and 12 with Firefox in safe-mode;
14. Repeated steps 11 and 12 with Firefox in normal-mode with a new profile;
The observed link-opening behaviour:
- Internet shortcuts (i.e., actual shortcut files on, say, the Desktop) open in Firefox without issue whether or not Firefox is already running. When this approach is taken, no additional firefox.exe processes are created. The process does not have any command-line parameters per Task Manager;
- Links clicked in Thunderbird open correctly if Firefox is not running: one new firefox.exe process is created, I get a new Firefox window and the link loads correctly. The firefox.exe process does not have any command-line parameters per Task Manager;
- Links clicked in Thunderbird yield the "Firefox is already running, but is not responding" message if Firefox is already running. In this case, I see a second firefox.exe process created. Per Task Manager, the new process has the command-line arguments '-osint -url "FOO"' where FOO is the URL I clicked.
From these observations I believe that the link hand-off behaviour is broken. I use a single profile using the as-installed shortcuts.
Intitial version: 33.0.2
Update: Updated to 33.1, still broken.

Under Tools > Options > Advanced look to see if the "check if Firefox is default browser on startup" Check this and then restart FF. If it isn't the default it should ask if you want to make it the default. Choose yes and it should open when clicking links again.

File, Send link doesn't open a new email. Using Firefox 11.0. Outlook 2010 is the Mailto default and W7 default email program. On the About:config page network.protocol-handler.external.mailto is set to regular font (not bold) "default Boolean true".

I assume you have tried toggling the setting in Firefox between Outlook and, say, Gmail:
orange Firefox button ''or'' classic Tools menu > Options > Applications
In the search box, type or paste '''mailto''' and pause for the list to filter.
Change the setting and OK to save it, then return to the dialog, change back, and OK again.
You also might want to toggle the setting at the OS level between Microsoft Outlook and the native Windows Mail client in a similar fashion. In Windows XP you could use IE's Options dialog, Programs tab, for this, but I'm not sure in Windows 7.
Since one possibility is a problem in your Firefox settings (including the possibility of interfering add-ons), and another is a problem at the Windows level (e.g., Registry settings), it would be useful to try to identify which one it is. One quick way to distinguish is to create a new Firefox profile. It will start up with all factory settings. You can switch back to your existing profile after testing.
First, I recommend backing up your Firefox settings in case something goes wrong. See [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
After closing Firefox, start up again in the Profile Manager as described in this article: [http://support.mozilla.com/kb/Managing+profiles Managing profiles].
With the new profile, can Firefox successfully create a message in Outlook?

When I click on an email address on a web page, a page no longer opens in my email program. Not sure if this is a problem due to Firefox or due to recent installation of Office 2010. I use a PC with Vista.

When I click on an email address embedded in a web page, a page would open in my email program with this address in the "To" line. I recently installed Microsoft Office 2010 and now when I click on an email address nothing happens. I am not sure if this is due to Office 2010 or a Firefox problem. I use a PC with Vista.

I had the same problem when i dl-ed a new anti-virus softward, but what I did help me reconnect Firefox again!
Here is what I did,
Go to open firefox browser-->option-->advanced-->network-->settings-->and change it to auto-detect proxy settings for this network!
It worked for you, hope it will work for you too =)!

Default email program setting won't stick

Hi,
I use Outlook 2011 on my MacBook Pro, with OS 10.7.5. Often when I click a mailto link (or choose "send as email attachment" in Word), Mail launches instead of Outlook.
I know how to change the setting for default email program in both Outlook and Mail. The problem is that the settings I choose do not stick. Somehow, Mail turns itself back into the default email program.
I could uninstall Mail although some people suggest this is a bad idea, and in any event it seems a bit of a cop out. I guess my preferences are corrupted? Will Preferential Treatment help?
Thanks for any suggestions,
LDS

I have the same problem. Changing the default option in Mail doesn't fix it (nor does selecting the option in Outlook to make it the default).

Firefox won't open, says profile may be missing or inaccessable, help pages not helpful

Firefox won't open at all. I get a "Profile Missing" window saying "it may be missing or inaccessable". This morning my connection quit mid-reset while it said it was going through everything and not to turn it off, since then it refuses to open. I tried everything I could think of. Tonight I managed to open an ancient IE and am here now, tried as much of the "Help Pages" suggestions as the site sent me to (none were what my computer has even though I'm running XP), but nothing fixed the problem. I removed Firefox and then re-installed, twice, it still won't open.
HELP!

I can find NO "profiles.ini" file anywhere. When I open the "default library" there are none of the files you say should be there.
I have tried a whole new download to update, it won't open because there is no profile.
I tried removing the program and re-downloading, still won't open.
I am not tech savvy enough to do much of the messing around you are suggesting. I need someone to help!
Also - this site is about the least "user friendly" site I've had to deal with in ages!
I should have been able to reply to the email, but you didn't allow that, too.
I need someone to somehow walk me through what to do. HELP!

Firefox won't open links from Mac Mail

Like everyone else Apple Mail links will not open in Firefox if it is already open. Clicking a link brings FF to the front but no page loads. Links work if FF is not open. Links work if command is pressed whilst clicking the link (opens in new tab in background).
Problem occurred after 32.0.2 update, it appeared to briefly resolve itself after 32.0.3 update, but stopped (I think) on next reboot.
Have monkeyed around for ages with different combinations of default browser and rebooting.
Will abandon FF and go back to Safari if this isn't sorted soon - shame.

I just want to link to these earlier threads so you don't get a lot of duplicate suggestions that have already been covered there:
* [https://support.mozilla.org/questions/1018542 Firefox won't open email links after update to version 32]
* [https://support.mozilla.org/questions/1023202 No tab opens when I click on a link if any Firefox window is already open]
(There might be others, but those are the ones I've seen)
Work is proceeding on [https://bugzilla.mozilla.org/show_bug.cgi?id=1017595 Bug #1017595 – Links from external applications sometimes fail to open when Firefox is hidden] but as you can tell from the title, this is focused on the problem of Firefox not coming out of hiding from the dock or coming out of hiding but not loading the page. If this also occurs when Firefox is not hidden at all, there may be a secondary issue. But hopefully solving the one will solve the other. Unfortunately, I don't know whether it will be in time for Firefox 33.

Read Mail button on the toolbar doesn't open my default mail program

I've just reinstalled Firefox 17.0.1 (and everything else) following a crash. I'm running Windows 7 Home Premium, with Windows Mail (not Live Mail) set as the default email program and I've added a Read Mail button to the Firefox toolbar: all this is exactly as it was before the crash. Windows Mail is selected in Tools/Options/Applications/mailto, and also runs perfectly from its desktop icon.
However, clicking on Read Mail doesn't open Windows Mail as it used to.
I get the message "The application could not be found, please use Toolbar Buttons's options window to correct this". I'm not clear on what it is I'm being directed to do. What and where is the "Toolbar Buttons's options window"?
Many thanks.

That did it. Thanks very much indeed.

How do I make other email programs my Default Email programs in Windows XP?

I'm not the most tech savvy person, but I've researched this, and haven't found the solution yet. Doing a search it tells you to go to Start>Control Panel>Add or Remove Programs>click on Set Program Access and Defaults>Click the Drop-Down menu under "Custom."
Then under "Custom," there's a heading in bold titled, "Choose a default e-mail program:"
I look to choose Firefox, but it doesn't exist. There are 3 options given.
1) Use my current email program, which is checked. (but how does it know what it is?)
2) Outlook Express (off to the right checked off is "Enable access to this program.")
3) Windows Live Mail (off to the right checked off is "Enable access to this program.")
- I know Firefox does not have email, but I figured someone out there has a similar problem and can help.
** I'm trying to add Yahoo, Gmail, and Aol mail to this list, but I have no idea how to do it.
** I've already changed the program used to open email links in the Firefox browser settings: Tools>Option>Application>scroll down to "mailto" and there are options for Yahoo, Gmail, Aol mail.
** On the Set Program Access and Defaults menu as I explained above, there are other headings in bold. The one above the "choosing a default email program" is "choose a default web browser." Firefox is an option there, so I didn't have to add it.

Hi the-edmeister. Thank you for your response.
How come in several screen shots I've seen online searching for this solution in XP, the default email programs listed contain at least one of: yahoo, gmail, and aol?
I understand they're web mail portals, but they are still appearing under the "Default Email Program" heading in "Custom."

Tried to use Restore to return to pre-Firefox4 but now Firefox won't open and won't uninstall.

After trying to maneuver the new Firefox 4.0 for a while and giving up, I wanted to go back to the 3.6.1.6 version. I used the Restore feature to try to go back to the pre-Firefox 4.0 dowload. Since then, Firefox won't open. I have tried to uninstall Firefox 3.6.1.6, which is listed in my installed programs in the Control Panel, but it doesn't do anything. At this point I don't know what to do. I want to re-instate the 3.6.1.6 version on my computer. Thanks.

You're in a bit of a pickle here because you can't use System Restore to revert to 3.6.16. You probably now have version 1.9.2.x which is in part, files which were not removed when you installed FF4
What you can try and do is use System Resore to undo the last restoration which should take you back to 4.0 again. If that fails, see this article: http://kb.mozillazine.org/Uninstalling_firefox
If the undo restoration is successful, do the following to revert to 3.6.16
Go to [http://www.mozilla.com/en-US/firefox/all-older.html Download Firefox v3.6.16] and download it to the desktop. If necessary, download the file with IE8 and choose to save it to your desktop when you see the prompt.
Then go to Add/Remove Programs, scroll down to Mozilla Firefox and remove it, choosing to keep your bookmarks, customizations etc., (don't checkmark the box).
Then reboot and delete the folder called '''Mozilla Firefox''' at this location: ''C:\Program Files\Mozilla Firefox''
Finally run the installation file you downloaded to the desktop earlier.
Your bookmarks, customizations etc., are maintained in a different location and will become available to you again once you complete the installation.

Then it just sits there forever, spawning and killing new processes. Firefox never appears.
Any ideas?

In order to test the problem, I think my suggestion is better; at least as a first try. Without Firefox running and without ~/.mozilla; no misconfiguration should prevent Firefox to run. The options you suggest will try to disable any problematic configuration. It can be usefull if you need to start Firefox to fix a configuration problem; but as a firt try renaming the ~/.mozilla is better because you are sure that Firefox can't read anything that can hurt it. Only after having figured out that a bad ~/.mozilla is the cause of the problem, we can try to fix the configuration (or restart with a new configuration).

Firefox won't open after re-installing and can't remove from control panel. What do I do?

After a storm and short power failure, I started having trouble with certain sites loading, and pages moving slower. I emptied my cache and defragged and ran total virus/ malware scan, but still had problem. (Pages loaded fine on AOL) I decided to uninstall Firefox and re-install to help fix problem. I did this, and now Firefox won't open, no matter if I double click, right click (open), or go through "all programs". I tried to uninstall and re-install again, but now I can't get it to respond through my control panel, either.

Try the procedures in the [[Firefox will not start]] article.

Firefox won't open following update. Can't open Profile Mgr, even when using entire directory path in cmd line

I'm running Firefox on a Windows 7 machine. Firefox won't open following the latest update. I've read the help articles and it seems like I need to create a new profile because my settings have likely been corrupted. I'm unable to open Profile Mgr, even when using entire directory path in cmd line. I've tried the following commands in the command line:
firefox -p
"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -p
Nothing happens with either command.
I'm also running Norton Internet Security. I read a help article Re Virtual Browsing features possibly causing a problem. The article said to check the virtualization setting in the internet security software and to clear the virtual cache. I went thru all of the settings menus in Norton Internet Security version 21.6.0.32 and I didn't see anything that looked like 'virtualization" settings, so I assumed that this doesn't apply to me.
If you have any ideas, I'd sure appreaciate your expertise!!

hello arcandl, when firefox isn't launching after you double-click on the shortcut this is sometimes also a sign of malware being active on a system.
you might want to try running a scan with some different other security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] and [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] which are specialised in removing adware and browser hijackers.

Firefox won't open for me. I keep getting the errors listed below:

"Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."
Nothing is running. I've killed all the firefox processes, restarted, uninstalled and reinstalled.
What can I do?
Thanks

Did you delete the profiles.ini file?
*http://kb.mozillazine.org/profiles.ini_file
You can use this button to go to the currently used Firefox profile folder:
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
*Windows: %AppData%\Mozilla\Firefox\<br>C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\
*Linux: ~/.mozilla/firefox/
*Mac: ~/Library/Application Support/Firefox/
You can use one of these to make Firefox create/use a new default profile:
*Delete the profiles.ini file to force Firefox to create a new default profile
*Use the Profile Manager to create a new profile
*Use "Choose Folder" when you create a new profile to select the location of a lost profile and recover this profile
