Unistall Firefox 4 to get FF 3.6.15 back.

I installed FF 4 and found out that most of the plugins I rely on haven't been updated so I uninstalled it thinking it would revert to the previous version but it didn't. I didn't choose the option to get rid of personal folders or whatever that option was when uninstalling. How do I get the previous version back? I use and rely on the plugins I have/had. Thanks in advance for your help.

To roll back:
First, back up Firefox settings: [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information].
Next, download and save Firefox 3.6 to your desktop for future installation. http://www.mozilla.com/firefox/all-older
Close Firefox 4, and uninstall it. Do not remove your personal data and settings, just the program.
Then finally you can reinstall Firefox 3.6. Unless you have installed an incompatible add-on, it should pick up where you left off. If there are serious issues, please post back with details.
Note: I haven't actually tried this myself!

When I clicked on Firefox IE opens instead. How do I get Firefox to load? I tried a system restore but it didn't work and I have scanned for spyware and viruses. I unistalled firefox and reinstalled and asked it to launch firefox when done and IE start

When clicking to start Firefox IE starts instead. I have unistalled Firefox and reinstalled and thought I removed IE also but it still opens. I don't know of anything I would have changed or done that would have started the problem.

Try to delete the files in the temp folder.
Download and save the Firefox installer to the desktop and start the installation with a double-click on the desktop icon.
You can find the full version of the latest Firefox 25.0.1 release in all languages and for all Operating Systems here:

I am trying to unistall firefox 20 and install the newest firefox version but it won't unistall. It remembers all my data if I install again.

I am trying to uninstall Firefox 20 and get the newest version which I think is version 21? It will not let me unistall it when I go to the start menu and hit on unistall a program and then choose Firefox. It shows, " Please wait while firefox is unistalling," but it never uninstalls. The green bar never moves. I tried to uninstall it manually and then install firefox 21 but then firefox 20 came back up (after I installed the new version) with all my saved data. It looked like it did before I uninstalled it manually, or thought I did.
I don't want any of my data. Just a fresh page!
I just want the firefox startpage, no google, yahoo, etc... I can't figure this out. Apparently, i am more technically challenged than previously thought!
If anyone can help, please let me now. I run Windows 7 pavilion notebook.

*Clean Reinstall
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 to see if this helped you!

I installed Firefox 3.6. Since then, I am unable to open pdf documents in Firefox. I get a black page. I tried opening the same document in Internet Explorer. It worked fine. I recently installed Nuance's pdf reader and thought that might be the problem.

I recently installed Nuance's pdf reader and thought that might be the problem. Uninstalled it. Still have the problem with Firefox.

Every time Firefox opened

How about if you right click on the PDF and select Save Link As..., and then open it locally from within Reader? Does it work ok then? That might be a workaround until the issue within the browser is resolved.

When I try to download applications such as Internet Explorer, Yugma, and iTunes in Firefox, I just get a window that says "save" or "cancel", but never one that says "run" so I don't think it's actually installing anything. It shows up in a "download" window, then the icon shows up on my desktop. When I click on it to launch it, it says "open with" and I get the same "save/cancel" window. It's a continuous circle. What am I doing wrong??
== This happened ==
Every time Firefox opened
== I don't know. I never downloaded apps through Firefox until all of a sudden Internet Explorer didn't work. ==
== User Agent ==
Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 1.1.4322)

What application are you choosing to open the files with?
Because of how integrated it is with windows IE should work. If it's not working, something more widespread could be wrong with your computer that would also prevent other browsers from working properly. Of course we'd love you to stick with Firefox, but you should get help with IE, too.

Installed Adobe dlm add-on and now Firfox will not open. I see the process starting in Task Manager but no window opens. Unistalled Firefox then re-installed but still no luck. HELP ME!

I installed Adobe dlm add-on and now Firefox will not open. I see the process starting in Task Manager but no window opens. Unistalled Firefox then re-installed but still no luck. HELP ME! I do not want to use IE! I presume it has something to do with Adobe DLM as ever since then it is not working.

I had this problem for a couple weeks as well and it was extremely frustrating considering we use firefox for all our company tasks. Here is the solution:
First of all if you have no bookmarks you want to save, then go directly to step 7. If you want to save your bookmarks first, then follow these steps.
1. Shut down the computer
2. Reboot and open firefox
3. Go to Task Manager, right click firefox.exe, and click END PROCESS TREE
4. WAIT 30 SECONDS! Then Double-click the shortcut to try and open firefox again
5.Repeat steps 3 and 4 until firefox finally opens (trust me, eventually it will)
6. Once it finally opens, backup your bookmarks,
7. Download a copy of firefox from there website
8. Uninstall from programs menu and make sure to check the box REMOVE ALL COMPONENTS
9. install the new copy and BOOM! it works
If it doesn't work, you're an idiot. If you don't want to reinstall firefox, then you're out of luck. Good Luck!

When I try to open Firefox I keep getting a message in a box entitled Profile Missing. Can someone help?

I recently upgraded my hard drive from the original 80gb to a MomentusXT 500gb Hardrive. I reloaded Snow Leopard, and transferred everything back onto my MacBook Pro with an Iomega external hardrive I use for back up. Everything else is working including Safari. But when I downloaded Firefox, it loads, and when clicking on the Firefox icon I get the message "Your Firefox profile cannot be loaded. It may be missing or inaccessible." Can anyone help me with this issue?

Check that you still have the default profile as listed in the file profiles.ini as Default=1.
If profiles.ini is present, but the profile that is marked in profiles.ini as Default=1 is missing then delete profiles.ini to make Firefox create a new default profile.

How do I get my "save and quit" back after updating to the latest version of Firefox on a PC?

How do I get my "save and quit" back I do not like having to close all my tabs and loose all that every time I close out of firefox. When I got the latest version of firefox I lost the ability for firefox to save my tabs when I close out of it. I have to go through the process of opening all my tabs and refinding the sites all over again each time I load up firefox. I can not find the place to change the settings to being back the way they were before firefox got the latest version. I want my "save and quit" back.

Firefox 4 saves the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session. 
You can use "Firefox > History > Restore Previous Session" to get the previous session at any time. 
There is also a "Restore Previous Session" button on the default about:home Home page. 
Another possibility is to use:
* [http://kb.mozillazine.org/Menu_differences Firefox (Tools) > Options] > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"

I'm trying to download the latest version of firefox. I get a pop up window that asks me what to open it with. I've tried adobe reader 9, acrobate reader 5, and real player. None work

OK, I'll take you through what happens. When I click download firefox 4 I get a pop up window that asks "what should Firefox do with this file?"
Below I have two choices:
_Open with (choose)
_Save File
So I go to choose and pick an application.
So I choose Acrobate Reader 5.0. Acrobate gives me a popup that says "Acrobat could not open firefox 4.0-4.dmg because it is either not a supported file type or because the fire has been corrupted....
So I try download again (I should point out that I am currently running Firefox 3.6.16) The popup that asks me to choose a file to open firefox 4.0.dmg pops up again.
So I choose Adobe Reader 9. Nothing happens. So I cancel.
So what application should I go to to open Firefox 4.0.dmg

I have Firefox 9 and getting yahoo 'freezing' on a number of processes like opening mail or loading attachments - can anyone throw some light on my challange pls - thanks :)

Yahoo seems to freeze in a number of ways - opening some mail (no particular type), adding attachments to outgoing mail, it also seems slow in loading some Ebay emails and stalls for a few seconds.
There are also some stalling type issues with some pages that I open in the browser as well - particularly FB or Ebay
I have cleared the cash, closed and reopened Firefox and I get rid of cookies and super cookies on each closure.
Is there anything else I can try to clear the issue?
Many Thanx and Happy 2012 to all :)

When I click onto the firefox webbrowser, I get the message "firefox has stopped working, windows will close the application to find a solution to the problem " This has been going on for several days, I've had to go back IE to access web pages

When I click onto the firefox webbrowser, I get the message "firefox has stopped working, windows will close the application to find a solution to the problem."

I had this exact same problem. I found this fix and it worked for me.
Step 1:
Browse to C:\Program Files (x86)\Common Files\Apple\Apple Application Support and copy the filen named QTMovieWin.dll.
Step 2:
Browse and past that file into C:\Program Files (x86)\iTunes.
Hope this helps you. I wish I could remember where I saw this originally so I could thank them.
Good Luck.
Anthony
