Firefox wont open .jpegs. but .jpgs do.

My Firefox 3.7.10 wont display .jpegs. It will always ask whether to download the file or open with whatever application. .jpgs work fine every time, so it doesnt appear to be mime types. It happens on every server.
When i go ahead and tell firefox to open those files with itself, the same thing happens.. it just wont display .jpegs for some reason.
I had the same problem with version 3.6.7 and i deleted the mimtype.rdf file in the application data directory. It WORKED! but now it is happening again, and i deleted the same file, restarted, and it still wont display .jpegs.

You should never select Firefox if you get an "Open with" download dialog. That will never work, otherwise Firefox wouldn't ask. If you ticked to do that automatically then you need to reset that action or you end up with Firefox opening endless windows or tabs.
See "Reset Download Actions": http://kb.mozillazine.org/File_types_and_download_actions
A possible workaround is to use this extension:<br />

Every time I try to go to any web-site I get an error msg that Firefox wont open up but after a minute or two it opens after all ?

Lets say I click on G-mail on my desktop shortcut. After a couple of seconds I get a box in middle of screen that says Firefox cant find that web site. Then the site will open up after a minute or so ???????????????

Hi,
If it was installed as a Firefox extension you can try to '''Remove''' it in Firefox '''Tools''' ('''Alt''' + '''T''') > '''Add-ons''' > '''Extensions'''.

On the other hand, if it was installed as a Windows application or Internet Explorer application, you may have to uninstall it via the Windows OS Control Panel, or via the browsers concerned. The [http://answers.microsoft.com/ Windows support] would be helpful.

Firefox wont open and the task manager wont open as well

My firefox wont open and when i try to fix it by managing profiles, it wont start up. when i try to go through the task manager it also wont start up. i dont know what i can do to fix this. ive tried uninstalling and installing tons of times. i just dont know what to do

Clint:
Welcome to Apple Discussions.
In terms of the Firefox issue. Boot the computer and log in. Then go to Apple Menu > System Preferences > Accounts > Login Items and see if Firefox is listed there. If it is, then select it and click the minus sign at then bottom left. The reboot the computer and try to launch Firefox.
A couple of other things to check. Open a Finder Window (Commnand + N when in Finder) and look in the sidebar. Do you see a white disk-like icon named Firefox? If you do, click on it, drag the Firefox icon into the Applications folder, then eject the white disk icon.
If neither of the above work, hold down Command + Option + esc. Do you see Firefox in the list of items to Force quit? If you do, select it and Force quit.
Please let me know if any of these work.
In terms of Dashboard, do you have the install disk for the OS you have installed?

Firefox wont open -= wont let me uninstall because I need to close Firefox!! I have Windows 7. I've been using Firefox for years.

Firefox wont open. When I try to uninstall it says Firefox is already running. When I go to task manager there is no Firefox process or application running

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

Thank you.

Firefox wont open as it cannot find the file HELP!!!

My firefox wont open, when i click anything to get on firefox it comes up with windows cannot find firefox
== This happened ==
Every time Firefox opened
== randomly after i shut down my computer once ==
== User Agent ==
Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; AskTbBT5/5.8.0.12304)

1. Close Firefox completely. (File->Exit on Windows/Linux, Firefox->Quit on Mac)
2. Rename the Firefox installation folder or move it elsewhere.
*Windows: This is usually C:\Program Files\Mozilla Firefox. "Mozilla Firefox" can be renamed to "Old Firefox"
*Mac: This is usually Macintosh HD/Applications/Firefox.app. Macintosh HD/Applications can be opened in Finder, and Firefox can be dragged to Trash.
*Linux: The install location varies based on distribution and installation method. Linux distributions usually don't put Firefox in its own folder, so this method can't be used.
3. Download Firefox again from www.mozilla.com and install. (Installation instructions for Windows, Mac, Linux )
4. If this fixes the problem, you can optionally check the old install folder for global extensions, components, or corrupt/locked files.

firefox wont open periode so please how can i fix the probleme

See [[Uninstalling Firefox]], try the [http://firefox.com/all-older.html older version], or the [http://firefox.com/beta beta]. If nothing happens when you try to launch or uninstall any of these versions, try these malware removal links:

Firefox wont open. firefox.exe is running but will not end

I can not for the life of me get firefox to open ive read count less problems threads and none of there fixes work. I have clean re-installed more times then I can count. Ran ESET, spybot, malwarebytes, repeatedly and got nothing and even try uninstalling them still nothing. what happens is when I start firefox I will get a loading icon for 3 sec then nothing and when I open my task manger firefox.exe is there but its not using any cpu and has 3000k of mem. When I try to end firefox.exe it will say it worked the first time but it will still be there, when I try again I get assess is denied even cmd TASKKILL cant kill it. everything else on my computer is working fine with no problems, Chrome which Im using right now works fine. the only time i can get firefox to work is in safe mode with networking other then that I cant get it to work for jack.

Hello blacy001, if you have an enable firewall try to remove any rules that blocks firefox access.
you can also check your graphics drivers, see: [https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration#w_search-for-and-install-new-graphics-drivers Search for and install new graphics drivers]
thank you

Hi, my firefox wont load websites but other browsers like internet explorer , chrome can . This problem occurs when i use my company's router ?

my company have two internet connection ; 1 is dsl connection , firefox working fine on it ; 2 is my company's own cisco 2911 cisco router with internet connection , firefox wont loading pages except just the homepage of google.com and that's it , and the problem is that whole company is using company's internet connection which means that firefox is death for all of us.
Reseting firefox works but just for one day and after that it stuck again. also tried other solutions like malware removal , re installing firefox etc but not worked
Thanks for any kind of solution

thanks alot for your quick reply fredmcd
i have searched alot on the internet and got the solution , it was a thread known as "l.yimg.com". every time i open a website ,it stucks in "transferring data from l.yimg.com" , so what i did is;
1) End the process "random.exe" from task manager
2) Delete all the history and cookies of the infected browser.
3) Opened Registry Editor and delete these malicious entries:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall\ L.yimg.com
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall\L.yimg.com \DisplayName L.yimg.com
HKEY_USER\.default\environment\temp
HKEY_USER\s-1-5-18\environment\temp
HKEY_USER\ s-1-5-19\environment\temp and so on
4) Search those malicious files on your hard disk and completely delete all of its components.
%AllUsersProfile%\{random}
%AllUsersProfile%\Application Data\.dll
it really worked for me , if anyone have the same problem then try it , hopefully it will work for you too.

Firefox wont open EML files for me any more.

I have saved some files on a flash-drive that I have opened in the past that will no longer open. They have the Firefox logo next to them but they wont open. They say they are EML files but now I can't open them.

Opening a .eml file depends on the email software that you use. For instance, Internet Explorer can now open .eml files since they are basically formatted in the same manner as .mht files are. Simply change the filename extension from .eml to .mht, and the file can now be opened on Internet Explorer. If you have Outlook, simply click the file and it should open easily in the program. If Outlook is not your default application that opens .eml files, simply right-click on the file, choose Open With and then select Outlook Express. Using Windows Mail, simply drag and drop the .eml file into one of your folders and click on it to open it.or u can use a FIREFOX EML file viewer software .

'''The past 2 days, I can't open my firefox Acct; I.E. opens fine but get Error with NO number, just says, can't find firefox something to do with a server?? I have windows 7 64 bit if that has anything to do with it.?'''

My itunes wont open! but my quicktime player works fine! help please

my itunes wont opena dn ive been told that if my quick time does not open then people have solutions but what should i do if my quicktime opens fine its just my itunes that wont work??
pleas help me i appreciate it

hi ho!
well i did what u suggested and the itunes only stayed there for about 10 seconds...
hmmm. i don't really like the sound of that. it's consistent with the malware problem (it seems to be a Qoologic variant) that has been causing "error-less" itunes launch failures for a lot of people since late October.
however, there are at least two other fairly common causes of error-less launch failures (and some rarer ones), so the diagnosis can be a bit tricky. look through the diagnostic procedures and treatment suggestions given in this post here:
http://discussions.apple.com/click.jspa?searchID=349706&messageID=1211446
if you do get itunes launching using the MSCONFIG technique, let us know the names of the start-up items you you have to disable. (letter-for-letter-capitalisation-for-capitalisation. include the filename extensions of the start-up items.)

Firefox wont open after closing

I Have Firefox 7.0.1 when i close down firefox it will not open the next time i try to use it.the only way i can get it to work again is to restart my computer then reinstall it.i have to restart my computer because it tells me firefox is open and i have to close it before reinstalling.any help would be great as i am a firefox fan.

Use task Manger or something similar to find and kill the process ''firefox.exe'' , you should then be able to restart firefox without needing to restart the computer or to re-install firefox.
* see [[firefox is already running but is not responding]]
You will need to sort out the reason behind the problem, try reading the above article it may help. Note always to exit firefox by using
*Firefox Button -> Exit

Firefox wont open for windows 7

I have downloader firefox installed and wont open the solution of the start task bar end processes will not work because it requires you to try and open again. wheni click on it it acts like it will load and nothing happens. new computer with regulare kapernsky checks no other issues. it was working orginally then just stopped i have uninstalled and reinstalled already with no success any answers?

Enable the guest account in Windows 7 and see if itunes will open in that account.
This will tell us if it's a user-specific problem, or system-wide.
Then work through the steps here,depending on what you find in the guest account.

Firefox initally opens fine , but when I try to open another tab Firefox hangs or I get an unresponsive script message

firefox initally opens fine right to my homepage. Then a few minutes later it starts hanging and I cannot scroll or do anything until it connects. Similarly when I try to open a new tab, the new tab either hangs forever, or I get an unresponsive script error message. I have tried resetting firefox and starting firefox in safe mode. nothing seems to help.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try these free programs to scan for malware, which work with your existing antivirus software:
