Can't open firefox since downloading 5.0
I can open internet explorer; but since downloading firefox 5.0, I can't open it.
A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, 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 and the updater process.

Can't open firefox after download. What's up with that?
Two weeks ago Firefox quit downloading attachments. Tried every online fix I could find and nothing worked. I uninstalled and installed the latest version. Program seems to download and it installs an icon on the toolbar but when you click on the icon nothing happens. I don't have time at work to debug a defective product. What a colossal waste of time. Why must software companies continue to dick with something that works perfectly and make it more and more complicated and unusable. I hate Internet Explorer but at least it works.
hello dowens, since this can sometimes be caused by malware active on a system, please run a scan with different security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes], [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] & [http://www.microsoft.com/security/scanner/default.aspx microsoft safety scanner].

I selected the option to download the Numbers upgrade and left it to do it. About an hour later I needed Numbers so tried to open the application but got a message saying the upgrade was in progress. Same several hours later. I rebooted my Mac and tried again with the same result. I went back to Upgrades & selected Numbers but it appears to have been installed yesterday so I can't re-install.
I wish I had a dollar for every person who claimed there was no way a file was saved in a later version only to find out it was.
If you post a link to it someone here will save it back for you. -

Download of Firefox 21 crashed, reboot no good, can't open existing nor download 22
I downloaded 21, then tried to open Firefox. I received a popup saying I had to reboot the computer. I did this several times. I still can't open Firefox or download another version. I keep getting the reboot message. I've thought of uninstalling and starting over, but I don't want to loose my bookmarks. What can I do?
NOTE: You will not lose bookmarks by reinstalling Firefox.
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.

I downloaded new Firefox but now can't open Firefox at all. It says it is not supported on my system. How can I get the earlier version which I deleted?

Downloaded Firefox 4 to my Mac OS10.5.8 and now can not open Firefox.
Downloaded Firefox 4 to my Mac OS10.5.8 and now can not open Firefox. The processor is 1.25 GHz Power PC G4 and 768 MB DDR SDRAM memory. Is it possible to go back to an earlier version that was running very well on my Mac?
Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox

After some time I realized I can not open Firefox anymore.
I have always used Firefox as my default browser and I really like their features, it's the best browser for me, but for 2 weeks I haven't had the possibility to open it.
I have tried many ways, such as try to open new tab, or try to open new windows, or try to open new private session but none worked. It's impossible to load Firefox. I have been searching on different sites to finally resolve my problem but it didn't help me at all.
I also reinstalled it many times but the same problem.
Thanks in advance and any help will be welcomed.sorry for the inconvenience caused to you. This may not be a problem with the fire fox instead this may be a problem with your computer.
Plz check your computer for virus mainly "Trojan". download an antivirus and run a full scan and also be updated to latest fire fox version. -
I can't open PDF files, can't open, update, or download Adobe Reader. (I had it until recently.) None of the "helps" seem to help. I can't even open Adobe Reader now.
Ignore the instructions about "edit options", to install Adobe Reader download the installer from http://get.adobe.com/reader/ and run the installer. Alternatively, a direct link for the latest version of Adobe Reader is:
http://ardownload.adobe.com/pub/adobe/reader/win/9.x/9.3.4/enu/AdbeRdr934_en_US.exe
The following article should help you set it up - [[opening PDF files within Firefox]]. -

Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can initially skip the step to create a new profile, that may not necessary for this issue.

I can't open Firefox. The home page doesn't come up, I just keep getting the Crash Reporter asking me to restart/quit but every time I do this the same message comes back. I've not been able to use Firefox for days now.
Since a few days we have a lot of crashes with [http://www.trusteer.com/product/trusteer-rapport Trusteer Rapport]. If you have this program, try to disable it and see if that stops the crashing.<br>
You can stop Rapport using Start Menu > Programs > Trusteer Rapport > Stop Rapport<br>
You can ask their helpdesk when an updated version of their product will be made available or, if you don't need this software, uninstall it.<br>
http://www.trusteer.com/support/en/report-problem<br>
If you do not have Rapport, then we need to have a crash report ID. When you send Mozilla a crash report it just puts it in a giant database. We have no way of looking it up without the Report ID. I have no idea what is wrong without looking up the crash report. Please get the Report ID of your latest crash report.<br>

I can't open iTunes since i did the last update in 10.6
I had the same issue, I trashed the application, not any libraries, or anything else. I then downloaded the ITunes apllication, and by the way this also happened with iphoto. Did the same thing, it asked to select library and I put in the old one. Then it worked fine.
BACK UP FIRST! -
Can not execute Firefox. So I updated it and reinstalled it. Then I reset it. For a couple days it worked fine. Now I am back to square one. Can not open firefox again.
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox and any leftover program files and then reinstall Firefox. Please follow these steps one by one:
#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) and confirm all upcoming messages.
#Now, uninstall Firefox by following the steps mentioned in the [[Uninstall Firefox from your computer#w_uninstall-firefox|Uninstall Firefox]] article.
'''IMPORTANT:''' On Windows, the uninstaller has the option to remove your personal data and settings. Make sure that you do '''not''' check this option; otherwise all of your bookmarks, passwords, extensions, user customizations and other Firefox [[Profiles|user profile data]] will be removed from your computer.
After uninstalling Firefox on Windows, delete the "Mozilla Firefox" program folder, located by default in one of these locations:
* '''(On 32-bit Windows)''' ''C:\Program Files\Mozilla Firefox''
* '''(On 64-bit Windows)''' ''C:\Program Files (x86)\Mozilla Firefox''
#Go to the Windows Start menu and click on "Computer".
#In the Explorer window that opens, double click Local Disk (C:) to open the C:\ drive.
#Find the "Program Files (x86)" folder or "Program Files" folder.
#* On 32-bit Windows, double-click the '''Program Files''' folder to open it.
#* On 64-bit Windows, you will see a "Program Files (x86)" folder AND a "Program Files" folder. Open the '''Program Files (x86)''' folder.
#Look for a '''Mozilla Firefox''' folder. If you find one, right-click it and select ''Delete'' and confirm that you want to move the folder to the Recycle Bin.
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.

Firefox just changed out of nowhere. I can only open firefox once... I used to have atleast 2 browsers up using them both on different sites, but now I can't have but one firefox browser up (not tabs, but firefox pages) Also when I am trying to upload images on ebay or any other site nothing happens... nothing pops up. I click it over and over and nothing even pops up. This is exactly what happens with the firefox browser in my first question... I can click the firefox icon a million times and nothing comes up. My tabs are all gone and it doesn't show anything like I had before this all changed? Did I reset everything some how? I do not recall clicking anything to go back... I do remember clicking an update because it kept poping up so I did it and that is the last thing I remember before this happened! UGHHH!
As I asked previously are you able to have tabs open as a window by using the right clicking option ?
When you close Firefox you should use
*'''Firefox button -> File -> Exit '''
Are you doing that ?
I suspect what may be happening is Firefox is hanging as it closes down.
* see [[Firefox hangs or is not responding - How to fix#w_firefox-hangs-when-you-quit-it]]_firefox-hangs-when-you-quit-it
* this explains how to check & if necessary kill the process [["Firefox is already running but is not responding" error message - How to fix it#w_end-firefox-processes]]_end-firefox-processes
A related possible problem is that you may have built up many copies of the restore files. These are stored in the Firefox profile. The easiest method of finding the profile location istouse
*use '''Firefox button -> Help -> Troubleshooting Information <br /> -> [Show Folder]'''
*see [[Profiles - Where Firefox stores your bookmarks, passwords and other user data]]
You need to look for the files ''sessionstore.js'' and numbered duplicates of that. Delete them.
* see http://kb.mozillazine.org/Firefox_hangs#Multiple_sessionstore.js_files
