Firefox 7.0.1 won't install

I did have 7.0.1 installed when it first came out. About a week ago I noticed a plug-in that was working fine had a slight 'glitch' in it (roboform 7.5.3). .long story so I'll skip to the chase...Decided to roll back Windows Vista 24 hours to see if it might fix the Roboform issue. That's when things went south...Firefox would crash upon opening...something with system restore? I don't know...so had to download and install IE 9 just to get online. Now I have downloaded FF 3.6.23 and at least I have an old FF back but when I try to upgrade back to 7.0.1...no dice. Hope someone can help me!

As soon as I posted the message I realised the download had failed to complete. Sorry, I'm so daft but thank you very much for your help :-)

Latest Firefox (23.0.1) won't install

Firefox crashed (not uncommon) so I went through the restart routine.
It decided to install the latest version, got as far as "Checking Compatibility of Add Ons" and sat with the 'scanning green bar' sliding happily grpm end to end.
After 6 hours I gave up, did a CTRL-Alt-Del and it said it wasn't responding when I tried to close it.
tried several times, all with the same result.
I Googled "Firefox won't install" and ended up deleting the Firefox folder in Program files (there go my add ons and everything else), manually downloaded, manually started the install...
Exactly the same result...!!!
Win XP, SP3, Fujitsu Siemens Esprimo 3000
Troubleshooting Information doesn't work as I'm having to use Chrome...

I'm getting very confused (but I'm in my 60s and am not a techie, so maybe it's to be expected...
I can't "Cancel the operation of checking the plugins" as the CANCEL button does nothing. The only way I can do that is with Windows Program Manager, where it tells me that it's "Not Responding" so I "End Task" and finally it shuts down.
If I then run the Profile Manager, absolutely nothing happens...
"If the Profile Manager window does not open, Firefox may have been running in the background, even though it was not visible. Close all instances of Firefox or restart the computer and then try again."
As far as I can see, at this point in the proceedings, Firefox isn't running - it's not showing anywhere and I have no idea how to find it if it is 'in the background'.
I'd really like to retain the Bookmarks and Passwords, and probably some other things I don't understand, if I can (it's an old age/memory problem - all the important birthdays were in ReminderFox for example), so I have created a backup copy of the profiles folder on a memory stick in hope...
Within Application Data\Mozilla\Firefox\Profiles\uxbwtgou.default, there are five extensions files - extensions.ini, extensions.log, extensions.rdf, extensions.sqlite and extensions.sqlite-journal...
Do I delete all of these?
Thanks

Firefox 3.6.13 won't install on my MacBook Air

When I attempt to install 3.6.13, I get a message that I lack the permissions for some of the elements.

I also have this problem and it just started in the last week or so. It seems to be dependent on my home network and the problem only exists with firefox. I have used chrome and IE8 with no issues. I can verify tomorrow that it only exists in my network but one thing I was able to test is that the problem exists even on my linux boot. I am totally dumbfounded with this problem and I can't find anything that will allow the gmail page to load. All other pages I have tried load fine, all be it a little slower than normal but they load. If anyone knows of a difference between firefox and all other browsers on how it goes through the router I would appreciate the info cause I don't know of any differences.

Videos on BeFun.be won't play-plugin required-which one? Tried to download microsoft media for Firefox plugin and it won't install(show up in plugin list)

On site BigFun.be video requires a plugin. Which plugin? I have tried to download Microsoft video player for Firefox 1.0.0.8 and it does not take or show up under plugins.

Hello SuperMax52,
Thank you for contacting Mozilla Support. It looks like the videos on that page require a WMV player plug-in. Please take a look at the following article to install the correct plug-in to play this content.
[[Play Windows Media files in Firefox with the Windows Media plugin]]
Please let us know if this solves your issue.

Firefox 17 or 18 won't install on windows 7

when I try to install mozzilla firefox 17 or 18 with window 7 everything goes great until I select 'RUN' then a 'RUN AS' window opens, if i select "CURRENT USER' the installation terminates, if I select 'FOLLOWING USER' & enter a user name & password it isn't recognised & installation is stalled

I'm having this same problem. It gives to option to run as Administrator or as the current user. I have the current user set as the admin. So I select 'current user' and nothing happens.

Firefox stopped working and won't install after I uninstall and reinstall.

Firefox stopped working one day. It would not load anything. I followed the directions and completely uninstalled and then reinstalled Firefox. It goes through the process and then says Firefox will load momentarily. It never does. Also, what do you have against hiring people to answer questions in person?

It is possible that your security software (firewall, anti-virus) 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.

Firefox 3.6.14 won't instal

1.The update downloads OK
2. I restart FF to instal the update
3. It then opens another download screen and gets stuck (for hours) claiming it is 'Connecting to the update server').

Problem now fixed with release of 3.6.15

Firefox Sync doesn't recognize my version of Firefox, won't install

Whenever I try to install Firefox Sync, it tells me "You are currently using Firefox 3.0.13," won't install, and suggests that I upgrade. However, I'm using Firefox 3.6.10, so I don't know how to resolve this. (Yes I tried downloading and installing the upgrade... this is still the result.) Any ideas?

Awesome suggestiont. Your solution worked perfectly and it was a breeze. Thanks!!

Firefox won't open, thought maybe deleted, updated all plugins, still no Firefox so downloaded Firefox, but won't install and message box keeps saying to close Firefox so it can install. HELP!

Last night my Norton told me to get rid of some of my programs so my computer would run faster. My computer was given to me with many programs already installed, and it is hard to tell from the names of programs what they actually do; but I figured if I could remove, then I could re-install if necessary. I removed a few before my brain was able to scream STOP. I cannot now remember which ones. No doubt this has everything to do with Firefox's "absence." (I do know that I did not remove Firefox itself, but possibly a program that plays a supporting role.) I'm dizzy trying to "fix" this, and if I was not able to LOL, I'd be crying all night! Thanks for any help.

Do a clean (re)install:
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* 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.
Your bookmarks and other profile data are stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder] (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

I followed your help directions on "Corrupt extension files" under "Unable to install add-ons", foolishly deleting the files you told me to. Now firefox won't open. I tried reinstalling firefox but it still won't open. Now what do I do?

I was trying to install the SEOQuake add on. After clicking install Firefox would hang up saying the script had timed out and asking if I want to stop it or continue. Didn't matter which option I chose nothing would happen. The only way to stop it was to close Firefox and restart. Tried restarting the computer. Still wouldn't install. Tried installing the Outwit add on and got the same error leading me to conclude it was a problem with Firefox, not the add on. I found this help page <http://support.mozilla.com/en-US/kb/Unable+to+install+add-ons?s=addons+won't+install&as=s> and did everything it told me to. Finally at the end I got to "Corrupt extension files". I foolishly deleted the files you told me to and now Firefox won't even start! I tried reinstalling Firefox and it still won't start. Tried restarting the computer. I have no idea how to get back to where I was let alone install the add ons I wanted to install. Please help. At this point I'd just be happy to be able to get Firefox working.

See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
Create a new profile as a test to check if your current profile is causing the problems.<br />
See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]]
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)<br />

Firefox won't install on Windows 7 64-bit.

I just installed a new hard drive on my system with Windows 7 64 Bit OS. Same that I used on the old hard drive that crashed. I downloaded the installer, and have tried to run it both with and without administrator permissions (by right clicking on the file). the UAC asks me if I want to proceed, i say yes, I get a flash of some window and then . . . . nothing. I have downloaded a another copy of the executable, with the same results. I am using my laptop to post this.

Firefox is normally pretty simple to install. Look at any security software you have installed is any of that somehow blocking or preventing the change.
* Please list all security related software you are using ?
Ensure it is a genuine copy of Firefox from for instance

Tried to install Firefox 14.0.1. Won't install, says I need XP, but I have XP.

Downloaded Firefox 14.0.1. Would not install. Got message: "This version of Firefox requires Microsoft Windows XP SP2 or newer."
I have dial-up and it took an hour to load, now it won't install. Very frustrating, particularly as I have Windows XP. Why won't it load?
Thank you.

Make sure that you do not run Firefox in compatibility mode.
You can open the Properties of the Firefox desktop shortcut via the right-click context menu and check the "Compatibility" tab.
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.

Firefox won't install for all users in Windows 8.1; only installs for administrator

Since moving to Windows 8.1, I have been unable to install Firefox for multiple users on this laptop. Firefox installs only for the Administrator (me), and does not appear on any other user account. When I try installing from one of the other user accounts (after entering my administrator password), it simply won't install.

Check that Firefox isn't set to run as Administrator.
Right-click the Firefox desktop shortcut and choose "Properties".
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
* Privilege Level: "Run this program as Administrator" should not be selected
* "Run this program in compatibility mode for:" should not be selected
Also check the Properties of the firefox.exe program in the Firefox program folder (C:\Program Files\Mozilla Firefox\).

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.

Adobe Reader 11.0 won't install through firefox - click save and then nothing else happens

Adobe Reader 11.0 won't install through firefox - I click save file when requested it switches to Step 2 of 3 but nothing is there and I have waited for a very long time for it to load. Anyone else have this problem?

Hi Pat,
After your last email I decided to continue to trouble shoot the problem and finally found the answer from another user. Oddly enough when using Firefox it will default to a location on your computer to save downloads. If it encounters a problem it doesn't identify it, the program just "loops" back to the start of the download sequence. Once I changed the folder that the downloads are sent to the original way of upgrading occurred without fault.
I will go back into the discussion group and credit you with the answer because I really appreciate your assistance.
Thank you, Jim
