I cannot get firefox to launch

I cannot get firefox to launch. I have tried to uninstall and reinstall without luck. Yesterday I did notice that my menu bar was missing and tried to reinstall a Google toolbar, but, had to close the computer before it was finished. Not sure if the two are related.
HELP PLEASE :-)

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.
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data when uninstalling.
* 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.

Have tried to uninstall and 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.

I can't get firefox to launch I'm getting a java script application - bbyln is nt defined

I can't get firefox to launch. I'm getting an error report:
java script application - bbyln is not defined

[ I've solve ] Well, I was too upset from the errors of babylon, sometimes it didn't allowed me to browse internet and oftentimes it ruined my new(default) tab opening parameters, so finally after damn research i figured it out how to get rid from these errors.; these files (software /errors) weren't visible anywhere e.g. control panel, system32 etc. i got em from C:\......, then i deleted em and got a complete calm. so here you go and remove both things;
C:\Program Files\Mozilla Firefox\searchplugins (bbyln.dll).
C:\Program Files\Mozilla Firefox\extensions (bbyln folder)
after to remove (babylon) relevant files restart your Mozilla firefox. WAIT. WAIT. don't forget to complement me...just say loudly....Well done dude, You're Genius ....O_o....!!!!
Sure, it'd be helpful because its not me its my experience talking to you.

I cannot get firefox to download -- a box comes up about firefox being a binary file (?) and do I want to save it or cancel -- I was told to save it, which I did but, after saving, I tried to get it to download again and this same box came back up

Cannot get firefox 4.0 to download - saved binary code download - download still doesn't work - cannot use computer until this is resolved

For Flash, could you try downloading the "full" installers from this page:
https://www.adobe.com/products/flashplayer/distribution3.html
In the first table, there are two rows for Windows: one for the ActiveX control for IE, and one for the plugin for Firefox. You might want to grab both. And try the .msi files instead of the .exe files to see whether those work better.
Will either of those install?
It's odd that on a newly rebuilt system your More System Details shows that you have a user.js file, which is an optional settings files used to override your previous session settings. This is not part of the standard Firefox installation, so if you did not create that file yourself, you may want to investigate or delete it. This article has more information on that: [[How to fix preferences that won't save]].

I cannot get firefox to open, could security setting interfer? I use AVG

On Wednesday 9/28 Comcast changed my modem and now I cannot get Firefox to open, when I click my mouse on the icon I get a brief hourglass and that quickly goes away and Firefox doesn't open.

The extension(s) that AVG installs can certainly be a problem, disable "AVG Safe" for a temporary solution, but it is better to reinstall AVG without the Link Scanner component, and as always be vigilant in rejecting additional crapware, please review all of the following but particularly information concerning "AVG Safe".

I cannot get Firefox as my homepage, it's covered by Xfinity. Please help.

''duplicate - locking - https://support.mozilla.com/en-US/questions/835447''
When Adobe updated it shut my computer down. When it restarted Firefox was not available. I uninstalled Firefox and reinstalled it but still cannot get Firefox, still nothing but Xfinity.
How do I get Firefox back as my homepage?

Xfinity made itself your Firefox Start Page? You can change that. Check out the tips in this article: [https://support.mozilla.com/en-US/kb/How%20to%20set%20the%20home%20page How to set the home page | How to | Firefox Help].
If that doesn't stick, it's possible you have an Xfinity add-on. You could check here and disable it if you find one:
orange Firefox button ''or'' Tools menu > Add-ons
On the left side, click Extensions
Any luck?

I had to change a password stored in Firefox, and now I cannot get Firefox to remember a new password.

As stated, I was required to change a password, yet the old password still appeared in the field, so I went into settings and deleted the old one, but now I cannot get Firefox to save the new password. And yes, I have wasted a lot of time attempting the "solutions" on the help sites, but nothing has worked. Thank you for any help.

Make sure that you do not run Firefox in (permanent) Private Browsing mode (Never remember history).
*https://support.mozilla.org/kb/Private+Browsing
The website may be using autocomplete=off to prevent Firefox from saving form data like name and password.
You can remove autocomplete=off with a bookmarklet to make Firefox store form data like names and passwords.
*http://kb.mozillazine.org/User_name_and_password_not_remembered
Note that Firefox won't auto-fill saved form data automatically when autocomplete=off is used, so you need to double-click the empty name field to get a drop-down list.

I cannot get Firefox to maximize from the toolbar after the update.

I have had no issues with firefox opening on my pc (running windows 8) prior to today. When I signed in there was an update (firefox) and I immediately noticed that I cannot get Firefox to go fullscreen from the task bar. If you hover over the firefox icon you can see the tiny window with the page loaded, but I cannot get it to maximize. I uninstalled and re installed twice to no avail. Chrome and Internet explorer work fine, but I need my Firefox up and running for work!! Please any advice will be highly appreciated! Thank you.

I will also add that I have a laptop running windows 8 that got through the update with no issues. I just checked and firefox updated to the latest version and works fine.

I cannot get firefox to read a .chm file. Old Netscape does, explorer does, chrome does. How can I get Firefox to read a .chm file?

In Firefox 24.0 -> Tools -> Options -> Applications, I cannot choose a program (hh.exe) to read .chm files. When I choose to open a *.chm file I have only the option of saving it, not to open it. Other browsers like Explorer, chrome, even old netscape 7.2 allow me to open it and the program finds I presume the hh.exe file and away you go. I cannot find a way to get Firefox (my favorite browser) to read chm files.

''As I recall, Netscape 7.2 was a hybrid version made long after AOL shut-down their Mozilla programming operations, and that version incorporated some Trident code used by IE - which might explain the CHM compatibility.''
''Not sure why Chrome handles it, though.''
http://en.wikipedia.org/wiki/Microsoft_Compiled_HTML_Help <br />
Microsoft Compiled HTML Help is a '''Microsoft proprietary''' online help format, consisting of a collection of HTML pages, an index and other navigation tools. The files are compressed and deployed in a binary format with the extension .CHM, for Compiled HTML. The format is often used for software documentation.
There used to be a CHM Reader Add-on for Firefox - https://addons.mozilla.org/en-US/firefox/addon/chm-reader/ - but it hasn't been updated since June, 2008 / Firefox 3.6. <br />
Sorry, Mozilla doesn't support "proprietary" formats such as that.

I cannot get firefox to access any web pages, main menu appears frozen

I have downloaded the most up to date firefox but cannot get the Start page to search for anything

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.
See:
* https://support.mozilla.com/kb/Server+not+found
* https://support.mozilla.com/kb/Firewalls
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.

I cannot get Firefox to retain my homepage after following the correct procedure.

I have used the same homepage for several years. Now, all of a sudden, <www.searchqu.com/406> seems to have highjacked my homepage. I cannot get rid of it. I have gone through the procedure of going to Tools/Options/etc., to reset my homepage to my chosen one. I have clicked OK, opened new tabs, clicked on the homepage symbol and everything appears to be OK, however the next time I open Firefox, www.searchqu.com/406 appears as my homepage. I would like to remove/uninstall/delete or otherwise get rid of www.searchqu.com/406 altogether or at least hide it from Firefox's view. Any help ??

See these threads about searchqu:

Rename or delete formhistory.sqlite (plus formhistory.sqlite-journal and formhistory.sqlite.corrupt and formhistory.dat, if they exist) in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder] in case there is a problem with the file that stores the "Saved Form" data.
This will remove all saved form data, so you may want to rename formhistory.sqlite to formhistory.sqlite.sav or move the file to another folder in case you need to recover some saved data.
