Firefox will not open links embedded in Microsoft Outlook emails - why

Firefox is set as my default browser. When trying to open a website via a link in an email, I get an error message that says "This apperation has been canceled due to restrictions in effect on this computer".

This is usually caused by a problem with a registry key.

Firefox will not open links

if i try to open a link in firefox, it will not open unless i right click and select open in a new page

Reload the webpage while bypassing the cache using '''one''' of the following steps:
*Hold down the ''Shift'' key and click the ''Reload'' button with a left click.
OR
*Press ''Ctrl'' + ''F5'' or ''Ctrl'' + ''Shift'' + ''R'' (Windows and Linux)
*Press ''Command'' + ''Shift'' + ''R'' (Mac)
Let us know if this solves the issues you are having.

Run As Administrator Firefox will not open links in emails

When Firefox is opened with Run As Administrator links in emails will not open. Is this normal?
Using W7 Firefox 23.

'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* Open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Once you get the pop-up, just select "'Start in Safe Mode"''
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''

FF 3.6.12 will not open links from external sources (Outlook, Dreamweaver, Digsby, etc)

I have just upgraded to Firefox 3.6.12 and links clicked in an external source will not open in Firefox.
Firefox is set as my default program for web browsing. I have tried to open links from Outlook, Dreamweaver, Digsby, and other programs.

I have the same issue, opening links from external programs like Word or Thunderbird does not work. This used to work before the update to 3.6.12

Firefox will not open links in gmail, but Internet Explorer will. Firefox is the default browser. The tab of the site it is trying to open reads: https:/w8mbn4 or https:/...urw8nbn4. No errors in the Error counsel are reported. Help!

I put in the WOT Addon, but Uninstalled it with not improvement.

I have exactly the same issue. After FF upgraded on its own to version 5, it won't open from start menu, taskbar, desktop icon, or even by pressing firefox.exe in program files directory. It does so by pressing a link at msn messenger, inside Outlook etc.
Disabling all addons, didn't help. Moreover, I can't start FF in safe mode or start profile manager (Start > Run> firefox.exe -ProfileManager).

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 a link in a new tab after I right click and then click on open link in new tab

When I right click A bunch of new options pop up and firfox will not open links in new tabs. Safe mode did nothing.

What do you mean with ''A bunch of new options pop up"''?
Can you open a new tab by clicking the plus button on the Tab bar?
Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test.

Firefox will not open new window after clicking on link

if I click on a hyperlink in an email message (Apple Mail) then Firefox will not open (if not running).
== This happened ==
Every time Firefox opened

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

Firefox will not open after unlocking Sempron

After upgrading to a new motherboard and unlocking Sempron processor, Firefox will not open. I have tried Firefox (safe mode) and rolled back to a previous version, but to no avail. It worked fine when I ran the Sempron 140 as a single core (even overclocked to 3.17ghz) on Biostar A785GE motherboard. I cannot find a crash ID to link to.

Maybe you restored to a version of Firefox that crashes or still have a virus problem.
(irrc some Firefox versions specifically had problems after Windows restores)
Follow up checking for malware and then try re-installing Firefox. I would also suggest you make a copy of your [[profiles|profile]] including all folders and sub files and put it somewhere safe as it may assist in restoring your bookmarks and information.

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?<br>
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:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
Please report back soon.

Firefox will not open without restarting computer

I do not shut down my computer as we use "Log Me In" so I and another person can log in from wherever we want, anytime. About 5 months ago the problem started. I can open FF when I come in every morning, but when I come back in the afternoon or later in the evening, Firefox will NOT open.. It does nothing.. I can click to open, use the drop down and select open, nothing happens. I have to restart my computer every afternoon in order to get Firfox to open.. So I have begun transferring all my links to IE as it does not have any problme like that.

Firefox will not open any new tabs since windows update

I have windows 7 64, and recently, when windows automatically updated, my firefox will not open any new tabs, manually or when opening a link...

Uninstall the Ask toolbar and it should work again. There is a compatibility issue with the Ask toolbar and Firefox that prevents new tabs from being opened.

Firefox will not show links to flv files. I get the error message for each flv file: "File not found. Firefox can't find the file at (path) .flv." Any mov and swf files in this same path will show. I can see the videos in Safari so the paths are correct.

Firefox will not show links to flv files. I get the error message for each flv file: "File not found. Firefox can't find the file at http:// (path) .flv." Any mov and swf files in this same path will show. I can see the videos in Safari so the paths are correct.

Is this a webpage that contains a link to a flv file? Please post a link to the page and tell us which link(s) are the problem flv files or else post a link to the .flv file itself.
Alternately, click on one of the sample FLV File links on this page and tell us exactly what happens:
http://www.mediacollege.com/adobe/flash/video/tutorial/example-flv.html
It might also help if you post the exact error message, including the path to the flv file.
'''Note:'''
Depending on how you have Firefox set up, clicking on a FLV File link will either save the FLV file to your computer or Firefox may open it automatically in an external application right after downloading (Firefox may ask you first). Firefox itself can't play FLV files so you need a "helper" application (or a plugin for flv files, if ther is one. You can see if Firefox is already set up to download or open FLV files by going to Firefox Preferences and looking in the Applications list. Find the FLV file type in the list and, if the action is "Open with", it should show the application that can play FLV files (e.g., VLC Media Player or Perian). See [[Managing filetypes]] for more information.

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.
