Java is not working with Firefox (but is working with Safari)

My computer is showing that Java is not enabled via Firefox. When I try to go into Tools/Add-ons, I see that there is no Java plug-in on that list (though I previously had no problem with Java). When I run software update on my Mac, it tells me my software is all up to date. Not sure what else to do. Java is working in Safari, so the problem is clearly with Firefox. I've tried disabling all my plug-ins, and clearing my cache. Nothing has helped.

Apple has removed support for the Java Plugin2 with the latest Java Update 10 for OS X 10.5 Java version, so the Java plugin is no longer available for Firefox versions and other browsers like Google Chrome that require the Java Plugin2.
There will be fix for this in Firefox 6 or in Firefox 5.0.1 if that version will be released, so that Firefox will find the plugin again.
I don't know if all Java applets will still be working on OS X 10.5 with this fix (Apple recommends updating to OS X 10.6).

Farmville will not load using Firefox, but it will with IE, for over a week now.

Farmville will not load using Firefox, but it will with IE, for over a week now. I have cleared the cache and cookies multiple times, updated flash player, did a virus and malware scan, allowed java script, allowed mozilla in the Windows firewall, contacted Zynga multiple times, and yet Farmville still will not load using Firefox, my main and preferred browser. I'm very frustrated and want this fixed.

Thanks for the advice cor-el, but if you would read the info I posted, I already did that, SEVERAL TIMES. That's not the solution unfortunately.

The visitor counter on my website no longer works on Firefox but still works in ME. How do I fix it?

I have a free visitor counter (by easycounter.com) on my website. It has been working fine in both Firefox (3.6.16) and MS Internet Explorer.
Yesterday, I noticed it no longer works with Firefox but still fine with MS IE.
Earlier in the week I did download a few add-ons recommended by Firefox.
Can anyone advise what the problem might be and how to fix it? The code for the counter is still intact on my page at www.qsl.net/ve3bdb.
Thanks in advance.
Incidentally, the page now takes forever to load when using MS IE, but I don't know if that's related.

No problems here with that visited counter on your website.
Which extensions did you install?
Start Firefox in [[Safe Mode]] to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Appearance/Themes).

I cant play videos on Facebook with Firefox but I can with IE. I am using Firefox 4.0.1

I cant play videos on Facebook with Firefox but I can with IE. I am using Firefox 4.0.1

Firefox now always stores the old session, and you can access it by going to the History menu and selecting "Restore Previous Session"
If you want Firefox to display the message to save the session, it can be turned back on by changing some preferences.
# Type '''about:config''' into the location bar and press enter
# Accept the warning message that appears, you will be taken to a list of preferences
# Locate the preference '''browser.tabs.warnOnClose''', if its value is set to '''false''', double-click on it to change its value to '''true'''
# Repeat this for these 3 preferences '''browser.warnOnQuit''', '''browser.warnOnRestart''' and '''browser.showQuitWarning'''
If you always open the last set of tabs, an alternative approach is this:
# Click the orange Firefox button, then select options to open the options window
# Go to the General panel
# Change the setting "When Firefox starts" to "Show my windows and tabs from last time"

Hello,
Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache.
Note: ''This will temporarily log you out of all sites you're logged in to.''
To clear cache and cookies do the following:
#Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
#Under "Time range to clear", select "Everything".
#Now, click the arrow next to Details to toggle the Details list active.
#From the details list, check ''Cache'' and ''Cookies'' and uncheck everything else.
#Now click the ''Clear now'' button.
Further information can be found in the [[Clear your cache, history and other personal information in Firefox]] article.
Did this fix your problems? Please report back to us!
Thank you.

Java pulgin is enablesed and still not working with firefox but is working with my explorer browser

Java 1.7.0_10 from Oracle Corp is working with my Explorer but when I go to a sight with Firefox, it shows that its not installed. When I go into Firefox's plug-ins, it shows that its enabled....How do I fix this?

Your plugins list only shows the Java Deployment plugin and not the Java plugin. 
A possible cause is that the Java installer failed to create the necessary registry keys that Firefox uses to scan for plugins.
See this page about a possible JavaFX installation causing this.

Java plugin not loading in Firefox 4.0b11, works fine in 3.6.13

Java plugin isn't loading in Firefox 4.0b11, but it works fine in 3.6.13 (and in Google Chrome too). It worked in Firefox 4 before, but broke somewhere around beta 5. libnpjp2.so is not really in the plugins folder, but is a symlink: /usr/lib/mozilla/plugins/libnpjp2.so -> /usr/lib/jvm/ia32-java-6-sun-1.6.0.12/jre/lib/i386/libnpjp2.so. When run from the command line, I see FF trying to load the other symlinked plugins (most totem related) but failing because they are amd64, and FF is built in 32bit. But no messages about libnpjp2.so (which IS 32bit).

this method works for Firefox 4.0 b11..!! [http://www.oracle.com/technetwork/java/javase/manual-plugin-install-linux-136395.html Manually install java plugin....]

Java is not running in Firefox, but runs in other browsers.

I am trying to run java in my Firefox 3.6.13 browser.
Java works perfectly in Internet Explorer, but I rather use fire fox.
I have java installed, and it appears in my (about:plugins) page as all enabled.
yet when I go to the java website to detect java, I end up watching the swirling bar go on forever and then it reports I have no java installed.
Every page that uses java appears blank, the page loads around the java perfectly, but its just an empty space where anything java is.
I made sure to check the control panel and make sure it is enabled for mozilla family as well as the next gen java is selected. unfortunatley no matter how many times I uninstall java/fire fox, and re install, Java will not work

The ''' "Search" ''' box isn't going to do you any good, you need the '''Run''' box. There isn't a "file" in the Firefox Program Files folder that you can use to launch the Firefox SafeMode. ''Firefox 4.0 has a fix to get around this problem in Vista and Win7, so you won't have to activate the '''Run''' box.''
See if this works in Windows 7:

My chatt on parelliclub don´t work with firefox but it works on explorer why?

When I go into chatt at parelli the java load and then everything gets black so I can´t chatt anymore with firefox. I have allways could before. So I tried the explorer and there it worked.

Did you ask "parelliclub" if they are compatible with Firefox 3.6.8?

Using my Web.Mail account with demon (THUS). I can NOT login using Firefox but I CAN with (choke) Internet Explorer. The login names and passwords ARE correct.

Initially, the Demon support desk asked me to reset all my browsing history which did nothing.
I tried Internet Explorer (7.0.5730.11) and this too failed initially but after several tries, I managed to log in and collect my mails.
I then logged out and tried Firefox, which failed (Incorrect log in name or password).
I immediately tried IE again and got in first time.
In Firefox (TOOLS, OPTIONS, SECURITY, EXCEPTIONS), I set web.mail.demon.net to permit the site any access that might have been denied.
The user name and password ARE correct (that would be too easy) but Firefox seems not to send one of these correctly ??? or is not sending something I.E. does.
aarghhh

From the Safari menu bar, select
Safari ▹ Preferences... ▹ Extensions
Turn all extensions OFF and test. If the problem is resolved, turn extensions back ON and then disable them one or a few at a time until you find the culprit.
If you wish, you may be able to salvage the errant extension by uninstalling and reinstalling it. Its settings will revert to their defaults. If the extension still causes a problem, remove it permanently or refer to its developer for support.

Some logins don't work in Firefox but do work in other browsers

I have a couple of sites that the logins don't work when I use Firefox but work perfectly if I use another browser such as Chrome or IE. I have tried uninstalling and reinstalling firefox including reinstalling back levels but nothing works. Any suggestions?

In what way are those sites not working?
Clear the cache and the cookies from sites that cause problems.
"Clear the Cache":
*Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"
"Remove Cookies" from sites causing problems:
*Tools > Options > Privacy > Cookies: "Show Cookies"
Also check the cookies exceptions to make sure that you aren't blocking cookies.
If clearing cookies doesn't work then it is possible that the cookies.sqlite file that stores the cookies is corrupted.
Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete other present cookie files like cookies.sqlite-journal in the Firefox Profile Folder in case the file cookies.sqlite got corrupted.
*http://kb.mozillazine.org/Cookies

Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do not click the Reset button on the Safe mode start window or otherwise make changes.
