Firefox 29 Does not Appear to Support Java 8 Plugin

Why won't firefox recognize the Java 8 plugin after a fresh install. I have FF 29. I had to install Java 7u55 instead. I even uninstalled Java 7u51 prior to the attempt.

Your issue is that you are running a 32-bit version of FireFox. I do not know if there is a 64-bit version for windows, but try looking for one.
Hope this solved your problem!

I wish to unistall Firefox so I can make a clean install to get rid of all the Yahoo tabs, but Mozilla Firefox does not appear in the list of programs in Window

I have tried the suggestions posted in mozilla support for removing Yahoo from the new tab and the default search, but I have not been successful. So, I thought I would uninstall Firefox from my computer and make a clean install. However Mozilla Firefox does not appear as one of my Currently installed programs in Control Panel\ Add or Remove Programs, and C:\Program Files\Mozilla Firefox\uninstall\helper.exe does not open or run. I fear I may have been the victim of some ?Yahoo malware. Any suggestions gratefully received.
I have Firefox 22.0 and my computer runs XP sp3.

Do you have the Default Tab extension?
Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.
*https://support.mozilla.org/kb/Safe+Mode
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
Use the SearchReset extension to reset some preferences to the default values.
*https://addons.mozilla.org/firefox/addon/searchreset/
Note that the SearchReset extension only runs once and then uninstalls automatically, so it won't show on the "Firefox > Add-ons" page (about:addons).
If you do not keep changes after a restart or otherwise have problems with preferences, see:

Firefox does not appear on screen when started from the start menu or the shortcuts, but task manager says the process is running.

No - I get the message basically saying "Can't run program while Firefox is running. Please close down Firefox & try again".
I rebooted my computer and it all works now - but that's weird it was happening before. Kinda weirded out that it happened at all.
To avoid that happening again, I still wanna know what to do to avoid it or fix it for next time. Thanks

Firefox does not appear in "all programs"

In my all programs list firefox is not there? I can find it by going into "computer" and looking for it there.
When I setup the install, I checked off "add ff to Start menu and task bar, neither of these occured.
There is no option to start ff in safe-mode.

Right click context menu does not appear only for Java 1.7, AWT TextField

I have been debugging some issues that an application has been having with Java 1.7 versus older versions. A new problem I have encountered is that the right click context menu does not function in any TextField. It works fine when running/compiling it with any previous version of Java. I have tried coding a simple test with a Frame, Panel and TextField to see if it might be something else in the more complex application that was causing it, but the simple test class has the same problem.
I have searched for other people having the same issue, but I have not found anything comparable. This seems like a huge change from one version to the next and I am surprised that I am not finding this mentioned anywhere else. Can someone point me to anything that discusses this issue that I am having? Does 1.7 require I implement my own context menu? I realize AWT is old technology, but this is an old, fairly complex application that doesn't use swing, and that is not going to change at this point.
My simple test:
import java.awt.*;
import java.awt.event.*;
import java.util.*;
class testF3 extends Panel
public static void main(String args[])
    Frame f = new Frame();
    Panel p = new Panel();
    f.setLayout(new BorderLayout());
    f.add("North", p);
    TextField tf1 = new TextField("", 20);
    p.add(tf1);
    Dimension medm = f.getSize();
    medm.height = 100;
    medm.width = 200;
    f.setSize(medm);
    f.setVisible(true);
}

In the past few days since upgrading to 4.0.4, the entire right-click context menu for links is gone and replaced with one item: "Copy Link" The "Open In New Tab" item, along with some other context items, is no longer there.
That's actually a problem with your particular installation of Safari, b. I've got all the contextual menu entries with my 4.0.4.
I helped fix one of these recently here at the forum. Try the procedure from the following post (it got back Tho's missing contextual menu entries):

Firefox does not open and support article has not helped

Firefox will not start when I click on the icon on my desktop but it shows up under Processes in the Task Manager. I have read the related support articles, but it has not solved my problem. I have previously been using Firefox normally.

If it opens in safe mode, you may have a problematic add-on. Try the procedure in the [[Troubleshooting extensions and themes]] article.

After update to Version 29.0, Firefox does not open Confluence Office Connector plugin Edit in Office links in

After the update from V28, Firefox stopped opening the Confluence Office Connector plugin Edit in Office links. These links continued to work from Internet Explorer and work again after downgrading from 29.0 to 28.0. Clicking the link results in no action from the browser to open the link.

It's a known bug of the extension. See [https://jira.atlassian.com/browse/CONF-33469 Atlassian's forum] for updates.

Firefox does not appear in 'set program defaults panel in Win 7', running firefox 4.1

Go to Tools -> Options -> Advanced Section: General Tab. On the bottom there is System Defaults. Click Check Now to see if Firefox is the default browser. Click Yes on the pop up window.
Firefox is now back in the list for default programs and it your default browser again.

Firefox does not recognize the last java update and some videos cannot be played and some sites do not load. What to do?

After the last update of Java, whenever checking addons, the report that is given is that the plugins "Java Deployment Toolkit 7.0550.13" and "Java(TM) Platform SE 7 U55" are outdated. Some videosites don´t load at all and some videos simply are not played. Any ideas of what goes on? (BTW, have already checked if the sites are down and no, they are not down).

Firefox does not "Appear"

I was running firefox 10 and it was hanging up when I was on Facebook playing Farmville. When I shut the computer down, Adobe Flash Player updated and it seemed as if Firefox updated (but I just updated it the other day). After Windows 7 reboots, the Firefox icon appears in the taskbar and the computer acts as though firefox is there - when you click on the taskbar icon you can hear it minimizing and maximizing. When I try and start firefox in Safe Mode, the icon in taskbar is there but it says "Problem loading page." I've tried to reinstall Firefox, to no avail. Can anyone help!!! I HATE using Explorer!

Open the system menu via Alt+Space and see if you can resize that window.
If that works then close Firefox to save that setting.

Firefox does not show up in the start up menu after dowloading

Every time I download Firefox I look in the start up menu and I can't find any file of Firefox. I have to download it every time I want to use the internet.

I'm not sure why you don't have a "Mozilla Firefox" desktop shortcut after you download and install Firefox. You said that Firefox does not appear in the "startup" menu. You should be looking in the Start '''All Programs''' list for a Mozilla Firefox icon (you may need to scroll up or down). If you don't see it, open the C:\Program Files (x86)\Mozilla Firefox folder and then right-click on firefox.exe and choose either "Pin to Start Menu" or "Send to -> Desktop (create shortcut) if you want a Desktop shortcut and it's missing.

Adobe Reader plugin :This sentence "le fichier ne commence pas par '%PDF-'" appears when I try to open some (not all) PDF files within Firefox (does not happen when I download the file)

This sentence (in french version) "le fichier ne commence pas par '%PDF-'" appears when I try to open some (not all, mainly bigger than 1Mo) PDF files within Firefox (does not happen when I download the file)

You mention Thunderbird, has the PDF file been emailed to you? If it has this support page from Adobe may help - http://www.adobe.com/fr/support/toptech/acrobat/319294/

I am trying to use a website that requires that my computer have the lastest version of Java, which I have updated and installed, however Firefox does not recon

I am trying to use a website that requires that my computer have the latest version of Java, which I have updated and installed Java 7 Update 51 (64-bit), however Firefox does not recognize that I even have Java on my computer. My computer is 64-bit
When I run "Verify Java Version" it show nothing is installed... but it is, I know that for a fact because it shows in my "Control Panel/Programs/Programs and Features".
When I go back to the Java Download page, the following message is visible:
"We have detected you may be viewing this page in a 32-bit browser. If you use 32-bit and 64-bit browsers interchangeably, you will need to install both 32-bit and 64-bit Java in order to have the Java plug-in for both browsers."
My question is this:
Is there a way to change my Firefox browser from 32-bit to 64-bit.... because it appears that this is way Java is not functioning properly?

Firefox needs 32-bit plugins, so you'll need to install 32-bit Java for Firefox.
No, you can't change Firefox from 32-bt to 64-bit. There is a Nightly 64-bit version (alpha) of Firefox, but it is used only to test for regressions until development is resumed.

The password save prompt box does not appear on logging in to certain password protected webpages; is there another way of adding their passwords to Firefox sync?

Dear Firefox tech supporter,
I am Currently running:
Firefox v6.0.2;
Windows 7 fully updated at 19 Sept 2011 15:45 GMT;
Norton Internet Security 2011 (using Identity Safe) fully updated at same time as Windows 7;
Extensions to Firefox-
Norton Toolbar 2011.7.1.3;
Symantec IPS 3.1;
Add to Amazon Wish List Button 7.1;
Minimap Addon 0.3.13
Plugins
The usual suspects from Microsoft, Adobe, Wacom, Apple and Google, all of which are checked and no updates currently found.
With webpages such as <https://shop.avanquest.com/members/?company_rs=51>, PayPal and Windows Live e.g. after correct login details are entered into the online form and login is performed successfully. The "key" symbol does not appear to the left of the "awesome bar", neither does the password save pop up box and so the login details for the site cannot be saved in Firefox sync.
This is not specific to https secure sites, as I have been able to save the passwords for several https secure sites and conversely, I have been unable to save the passwords for some http non secure URLs. I have ensured that, whilst trying to enter a page or site into Firefox sync, it has the only tab open.
There does not seem to be a way of manually entering website details (URL, User Name, Password etc.) into Firefox Sync; how can I save the password details for such sites?
Thanks in advance for your help,
Chris Morris
