I had to uninstall Firefox (SpeedBrowser would load when I opened), now Firefox won't install after several hours of loading. Is there a setting I need to fix

I tried several times to install Firefox. I have Win7 and it wont install.

Hello yolanda.alexa, you have to uninstall the SpeedBrowser from your windows programs, go from Start/Windows > Control Panel > Uninstall a program > right-click any related to Speed Browser > Uninstall.
also please try these free programs to scan for malware, which work with your existing antivirus software:

Firefox becomes very sluggish after several hours of usage

In the past 2 weeks, after several hours of use, firefox becomes very sluggish. Cannot switch tabs easily. Cannot type emails easily, etc. If reboot computer, works fine at first, but again, after several hours, becomes sluggish again. This happens to both my computers which are on a network. A technician suggested a virus, but have not seen any virus messages. Use AVG 2013 virus software.

A possible cause is security software (firewall,anti-virus) 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 and the plugin-container 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.

Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

Firefox won't install after uninstall

Hey all,
I just bought a new 2012 rMBP and a local authorized computer repair shop transfered over my data from my old laptop, which was a macbook as well. The only reason i had them do it is because my old laptop was subject to severe water damage, and I had no way to access the HDD
Anyway, he transfered over my apps, files, and everything. Firefox was transfered over as well. I uninstalled firefox by dragging it from the applications menu to the trash, and then downloaded the current copy (the one that was installed on my old laptop was 6 releases behind). I go to install the newly downloaded copy and it tells me there is already a firefox installed, and i can replace, leave it alone, or stop. If I pick "replace" it gives me a message of:
"The operation can’t be completed because some items had to be skipped. For each item, choose File > Get Info, make sure “Locked” is deselected, and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access, try again."
I've searched for firefox files and there are none.
Where do I go from here?

Back up all data if you haven’t already done so. Before proceeding, you must be sure you can restore your system to the state it’s in now.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the page that opens.
Drag or copy — do not type — the following line into the Terminal window, then press return:
sudo chflags -R 0 /Applications/Firefox.app
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning. If you don’t have a login password, you’ll need to set one before you can run the command.
Try the installation again. If it works, you can quit Terminal.

Firefox won't install after downloading.

I recently was having troubles with Firefox, I was running Firefox Beta 18 - it started saying it could not update. So after repeat failed attempts, I figured I'd uninstall it and re-install a fresh version. It will download, I can find the file folder, but even when I try to run it as an administrator it won't open the installer. I downloaded three different versions, all do the same. I'm currently running Windows 8 and have had Firefox for over two years on Windows 7. When I upgraded to Windows 8 it transferred seamlessly with no problems. I'd like to be able to use Firefox again.

You can try booting the computer in Safe Mode with Network Support. This can be done by opening msconfig.
# Enter Desktop mode by pressing Windows Logo + D
# Windows Logo + R
# Type ''msconfig'' and press Enter
# Click on the ''Boot'' tab and choose Safe Mode with Network
# Click Apply/OK
Then restart your computer and it should automatically enter Safe Mode with Network Support. From there, find your installer and try running it again. When it's done, make sure to go back to msconfig and uncheck Safe Mode.
Finally, restart the computer.
Hope this helps!

Firefox 4 wont even start up now. how do i uninstall firefox 4 and install previous version

want to know how to uninstall firefox 4 and install previous version. also where to get download of previous version

Your problem is caused by the Ask Toolbar which you have installed. There are compatibility issues between Ask and Firefox at the moment.
Please do the following to ensure a clean installation. 
#Use Internet Explorer to download Firefox 4.0.1 from this link: [http://www.mozilla.com/en-US/firefox/fx/?ref=logo Download Firefox 4.0.1] and choose "'''Save'''" when you see the prompt. Then save it to your desktop. ''Do not choose "Run"''. 
#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. 
Next, click the Firefox button and go to Add-ons, then Extensions. Find the Ask Toolbar in there and click "Remove".
If you would still prefer to use the previous secure version, use this download link instead of the one to v4.0.1: [http://www.mozilla.com/en-US/firefox/all-older.html Download Firefox v3.6.17] Otherwise the installation procedure and removal of the Ask Toolbar is the same.

I having same problem is there a solution ?

I wish to install Mozilla Firefox as my Browser having re-installed XP Home Edition on my 'old' Dell losing my Service packs, so Firefox won't install.

As I am on the early XP, without any Service packs, I want to up-date to SP3. The Microsoft Website won't offer any help. Firefox won't install and I need a prompt to send me in the right direction.
I am using IE version 6.00 and it is refused access to updates because it is so old.
The 'old' Dell runs well but had suffered my bad management one night resulting in the need to re-install XP. It is my second PC and I am running 8.1 on my newer machine, so I can access help topics.
What is my next step please?

See if this works to get the XP2 and XP3 updates.

What is the Firefox start page looking for when it tells me I'm not using the most current version and need to update Firefox? The check for updates button says my version is up to date, but the start page disagrees. Is there a setting I need to adjust?

Okay: My start page is the one Google provides: http://www.google.ca/firefox?client=firefox-a&rls=org.mozilla:en-US:official and frequently it has a note underneath the search box that "You're not on the latest version of Firefox. Upgrade today to get the best of the Web!" But when I check for updates on the About Firefox window, it says my Firefox is up to date. So what is the start page looking for? Is there some setting I need to adjust? Or is this a Google marketing ploy to get me to switch to Chrome?

I tentatively think I have the solution; this is for when the session id value 'thing', in about:config, referred to in other answers is already on the default/rest state.
I am assuming, I don't what to imply certainty in-case there is a value wrong in our browsers, that the problem stems from the fact that our homepage is no longer the default for Firefox.
So, go to 'Options'>'General' and delete the homepage. This will reset it to the new address, which is 'about:home'.
I hope this helps some people.

New yahoo mail no response when compose email or reply to sender is selected EI9 browser works ok , is there a setting in Firefox? thanks.

When I upgraded to the new yahoo mail I found I was unable to compose new emails or reply to senders. When I select these functions nothing happens. Internet explorer 9 works fine.
I have McAfee Security Center firewall etc.
I have not noticed any other problems with the Firefox browser.
I contacted yahoo mail support and they tell my email account

Thanks...

When I try to get online, my computer reboots. I had to uninstall Firefox 5 and go back to Internet Explorer.

I had to update some drivers. After doing that, every time I try to get online with Firefox 5, the computer automatically reboots. I had to uninstall it.

I see. Well, I just tried to make IE my default browser, but it did not solve the problem. I receive the same script error when I view the image. (I may not have explained this thoroughly enough at first - I do get to view the image after answering the error message, but the print button embedded in the window doesn't work. Before, I never had a problem with viewing or printing.)
I imagine that at this point I will either need to communicate this to the IE people, or possibly revert to an older version of IE.
