Java won't work on Firefox, while it works on Safari on a Mac.

I have a MacBook Pro and downloaded Firefox 3.6 for it. Now I've realized that Java plugins won't work in Firefox for some reason, while they do work in Safari that came with the Mac. The problem wouldn't be with Java, since it works on Safari.
The Java-related plug-ins I have installed in Firefox are the Java Embedding Plug-in 0.9.7.3 and Java Plug-in 2 for NPAPI browsers.
When I go to a page that contains a Java applet, there is no error, the page says it's done loading, and there's a blank spot where an applet is supposed to be.

Actually, I have both plugins installed in Mac OS X 10.6, verified by entering '''about:plugins''' in the SeaMonkey 2 Location Bar (address bar)
Java Embedding Plugin 0.9.7.3
 File name: MRJPlugin.plugin
Java Plug-In 2 for NPAPI Browsers
 File name: JavaPlugin2_NPAPI.plugin
This is a new iMac computer I just set up last week running OS X 10.6.4 with all current Apple Software Updates. I have SeaMonkey 2 installed on it, but not Firefox.
I have Java 6 Update 20 ( 1.6.0_20 ) installed, verified by going to the test link in the KB article I posted above,
http://javatester.org/version.html
Java 1.6.0_20 (referred to as "Java for Mac OS X 10.6 Update 2" on the page cor-el linked) should be available from Apple's [http://support.apple.com/kb/HT1338 Software Update] feature.
Another test link you can try (from about:plugins):
http://browserspy.dk/java.php
I think that the Java Embedding plugin is something that Mozilla includes with all its current browsers (Firefox, SeaMonkey, Camino) based on: http://plugindoc.mozdev.org/OSX.html#Java
...which links to http://javaplugin.sourceforge.net/

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).

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 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.

Why are flash games not working properly on Firefox, while they work perfectly on other browsers?

I own a MacBook os x 10.5.8 Intel core duo.
My problem started a few weeks ago, I tried playing a flash game, first it came up that i didnt have flash, which I did, so I ran an update but I already had the latest version.
I gave up on the games on that page and went to newgrounds.com, but turns out everytime I try to play a game the controls wont work properly on any game.
I thought it might be my flash, so I went to chrome and played the same game, no problems, to opera, no problems, to safari also no problems. So the problem is my firefox and the flash plug in? I already uninstalled it and re installed it, downloaded it again and followed every piece of advice I could find about this, nothing works.
I appreciate some help with this matter, I like working with firefox, wouldnt want to change to other browsers.

Hi gorgonzola357, there are some platform-specific differences between Windows 7 and MacOSX that may be relevant.
Have you tried disabling the new protected mode in Flash 11.3, since that feature is currently being debugged? See this support article from Adobe under the heading "Last Resort": [http://forums.adobe.com/message/4468493 Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?]

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).

Soical buttons not working in firefox & Chrome but OK in Safari

My webiste has been up and running for a month now but I've now noticed (among an array of other Muse bugs... aaaggghhh) that the 'Facebook Recommend and the 'Pin it' social widget buttons don't work in Firefox and Chrome but they do in Safari?
http://www.thinksmartresumes.com.au/parthorus-resumes-design.html (freebie tab)
Also on this page, the 'LinkedIn share' button works fine in Safari and Chrome but not in Firefox? See screen shots...
The Muse Team (ie Danni Beaumont) clearly state in all the tutorial videos that they guarantee multi-platform user friendly code.... I spend half my day finding bugs between different browsers? Not happy.

I am having similar issues - the URL that the plugin insists it wants to have complete (with http:// at the front) is being concatenated with another "http://" when it is rendered on the page.
This is the URL I have in the properties for the button:
But this is the URL that shows up in the Share dialog:
If I take the http:// OFF the property for the button (so, I start with "www...."), the widget doesn't render. I get an error that the thumbnail can't draw.
Yes, annoying.

URL Does Not Work in Firefox, but DOES Work in Other Browsers

The following URL does NOT work in Firefox. However, it DOES work in Internet Explorer and Google Chrome:

Animation will not work in Firefox. It works in Safari.

I created an animation and uploaded it to wordpress.com. Using Firefox, I went to the website to play the animation. But the animation wouldn't appear. I checked it again using the Safari browser. And the animation appeared and it worked fine. Why will it not work in Firefox? I uploaded the newest version of Adobe Flash and installed it. And I have the most recent version of Firefox on my Mac computer. Will someone fix my problem please? Thank you.

Hello. Thank you for the information. I checked if the flash plugin is activated in the Firefox browser using your instructions. And it is active. The problem seems to occur with all of the flash containing web pages in my wordpress site. My art machine animation and other animations on the site do not appear when the pages load. I checked other websites containing swf file animations and they work.
I'm providing the information that you suggested. And it is as follows...
Operating System: OSX Yosemite, version 10.10.3
Web Browsers: Safari, version 8.0.5 (10600.53.17)
                                  Firefox, version 37.0.2
                                  Chrome, version 42.0.2311.90
Problem: In my wordpress.com website, none of the .swf flash files will appear using the Firefox nor Chrome browsers. But they do in the Safari browser.
Direct link to the problem sites are as follows: Firefox- 3 Art Machine | Nora Christians
               Chrome- 3 Art Machine | Nora Christians
               Safari- 3 Art Machine | Nora Christians
The code that I used to upload the .swf file to wordpress.com is the same for all three browsers. I didn't write any different codes for any specific browser.

Windows 7 cleartype NOT working with Firefox 6 (it worked with Firefox 5)

As soon as I upgraded to Firefox 6 on Aug 16, 2011 - the Windows 7 cleartype stopped working within firefox.
The text now looks blurry and light. I disabled all addons, tried safe mode. It was always the same thing.
To fix this, I manually downgraded to Firefox 5. As soon as I did this, the cleartype was back. The text was dark, the way it always was.
I have the same addons with both versions and I've tried to repeatedly install both versions, but with the same end result. Windows Cleartype doesn't seem to work in Firefox 6 (compared to Firefox 5).
Firefox 6 is amazing, but non-compatibility with Windows7 cleartype is a big issue. One of the best features of firefox is the tinkering it allows with it's fonts, and the clarity of text it allows. Sadly this doesn't work in Firefox 6.
I've downgraded to Firefox 5 for now. Hopefully this will be resolved soon..

I had the exact same issue after updating. I even resorted to downgrading yesterday after not finding any decent work-around for this, but when it forced an update today upon starting Firefox I just had to clear this up. Here's what you can do:
# Type '''about:config''' in the address bar.
# Type '''gfx.font''' into the filter bar.
# Focus on the following parameters: '''cleartype_level''', '''enhanced_contrast''', '''gamma''', '''pixel_structure''' and '''rendering_mode'''. Forget about the rest.
# Press Start and type '''regedit''' into the search field.
# Once there, choose the following: ''HKEY_CURRENT_USER - Software - Microsoft - Avalon.Graphics - DISPLAY1'' and note down each value represented in the data column within the brackets. For example, my '''ClearTypeLevel''' value is 100, '''EnhancedContrastLevel''' is 400 and '''TextContrastLevel''' is 2.
# Now that you've found these values, go back to the configuration in Firefox and right click on the '''cleartype_level''' parameter, and choose Modify. Now enter that very same value from before (100, for me) in there. Do that with the rest of the values. I put my '''rendering_mode''' as 2, which could coincide with the '''TextContrastLevel''', but it might not, but the '''rendering_mode''' values range from -1 to 5, so see which works for you.
# To change the '''gamma''' and '''pixel_structure''', go back to the '''Registry Editor''' like before, but this time follow this: ''HKEY_LOCAL_MACHINE - SOFTWARE - Microsoft - Avalon.Graphics - DISPLAY1'' and note the values within the brackets from there.
# Replace those values to the ones in the configuration and you're all set!
If you want to read more about those configuration parameters and their values, [http://kb.mozillazine.org/Thunderbird_6.0%2C_etc.#Font_rendering_and_performance_issues here's] a great article of sorts about it. It's about Thunderbird 6.0, but everything mentioned there correlates with Firefox 6.0.
This is as close as I've gotten to the text looking like it's supposed to and if even this doesn't work for you then I'm open to any and all suggestions anyone might have : /

The youtube player won't work in Firefox. It works fine in IE. I rebooted Firefox & rebooted my computer, but all I get is a black screen where the player should be (no picture, no controls). Can you help me out

Players in other sites are working.

Hello!
First you might want to check about:plugins to get some information about your Flash plugin status.
If your plugin version is stated there along with more information - it means that its installed. Furthermore, if the plugin is outdated, well, this can be the first cause of the problem. Please go to http://www.mozilla.org/en-US/plugincheck/ . I your plugins is outdated, please update.
If the problem persists, try creating a new Firefox profile see where it gets you.
More information here https://support.mozilla.com/en-US/kb/Managing-profiles
If still no go, we'll have to send your data to our dev team, meaning filling a bug in bugzilla under the core product and plugin component https://bugzilla.mozilla.org/ . but i hope we won't get there.
Please let me know if any above worked for you
Cheers!

Flash is updated but flash applications don't work when viewed in Firefox, while they work in IE

in several applications, there is a flash application that doesn't work -- flash movies don't play, etc. I checked Tools and it tells me that Flash is loaded and current. I'm stumped. This is a brand new computer.

See http://kb.mozillazine.org/Testing_plugins
Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
See:
* [[Troubleshooting extensions and themes]]
* [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
