Java suddenly is no longer working on Firefox, even though it says it is enabled

Just today, I have noticed that Javascript, and anything related to Java will not run on Firefox. I've looked far and wide, uninstalled JavaFX, reinstalled Java 3 times, attempted everything, but no matter what, Java will not work and Firefox will report the Applet is running fine.
I'm running the latest version of Firefox, along with Java SE7 U17, which is the latest version of Java. Is there any way to fix this? Also, Java has also ceased to work on my computer itself, but it is most noticeable on Firefox where I can't use scrolldown menus, or view videos that require Javascript (It either prompts me with "Plugin/file not found" or it simply doesn't load). I can still view YouTube videos.

Disregard.
Problem solved itself after waiting a day, and reinstalling Java while restarting the computer inbetween uninstalling and reinstalling.

Why does user_pref("capability.policy.default.Location.href", "allAccess"); no longer work in FireFox 4? How can I re-enable this feature?

On upgrading to FireFox 4 from 3.6.15, I noticed that my capability.policy.default items in the prefs.js file were no longer working (the custom site that I run locally needs access to this attribute, amongst others) - how can I go about returning this feature back on?
Example CAPS entry:
user_pref("capability.policy.default.Location.href", "allAccess");
I've had to downgrade again to 3.6.15 until I can get this to work.
Tested on Windows XP (SP3), and using existing/new profiles in FF 4.0 and using prefs.js and user.js - nothing can get the Javascript code to read the location.href and getting an error generated in the error console.
Also tested on Mac OS X 10.6.7 with FF 4.0 - still no luck getting capability.policies to work.
Please help...

I've been beating my head against this problem for a few hours, and I finally solved it. I'd been trying to set a capability policy using the "magic" default policy, and nothing would work - I could disable properties and functions of the Window object, but not the Location object.
It turns out that if I set a custom policy name, and named the specific sites I wanted the policy to apply to, it works! The only hitch is that you'll have to build a whitelist of sites that are allowed to have this kind of access, instead of allowing any site to access it by default. I think this is prudent security policy, in order to prevent XSS attacks.
So, for your case, instead of this:
user_pref("capability.policy.default.Location.href", "allAccess");
use this instead:
user_pref("capability.policy.policynames", "hrefaccess");
user_pref("capability.policy.hrefaccess.sites", "http://example.com http://www.example.com");
user_pref("capability.policy.hrefaccess.Location.href", "allAccess");
I haven't tested this code, but a similar implementation for my problem did the trick. I hope this helps!

Can't get flash working on firefox even though plugin is installed.

I am trying to get flash to work with Firefox on my mac OSX 10.6.8 VM. I had an old version of flash and I just updated it. According to adobe's help page (http://helpx.adobe.com/flash-player.html), the most recent version *is* installed but the animation on that page doesn't appear, nor does any other flash-based site seem to work. In the add-ons page, shockwave flash is present, and the setting is "always activate." In every way it seems to be successfully installed, but firefox has no idea it is there. Flash works just fine for Safari. I've uninstalled and reinstalled flash completely, several times. I've restarted my VM at different points during this process. Elsewhere on this site I found advice suggesting that I try to delete pluginreg.dat. No dice. If I check the about:plugins page it states that flash is present and enabled. But it simply doesn't work.
The only possible thing I can think of is that while flash is installed in the default directory, firefox is in a custom directory. (I use this VM for automated browser testing so I have several versions of firefox installed. Flash isn't working on any of them.) Any advice?

Sadly, that icon doesn't even appear for me. I can click the empty space where the icon should be and select "settings" but the settings box won't appear. I tried in the safari I have installed on the same vm, the settings box would appear but I couldn't actually click anything or make the box respond. This appears to have been a known issue with flash v10.whatever but I'm on v13. Is there another way to access this hardware acceleration option for flash? I already have it disabled for firefox.

Fallback for Spengo not working for Firefox even though it works for IE

Hi,
I am using firefox, 3.6.8. I am trying to connect to an AppServer which uses SPNEGO as an external user. I have a fallback set up so that if it is an external user and SPNEGO fails, the AppServer will revert to Applicate Security which is simple BASIC authentication.
The fallback works ok for IE but not for Firefox. If I try to access the site, firefox just tells me:
SPNEGO Authentication not supported on this client and the fallback never happens.
== This happened ==
Every time Firefox opened
== When I first tried it

Did you try any of this:
https://encrypted.google.com/search?hl=en&lr=&tbs=qdr%3Ay&q=%22firefox+SPNEGO%22&btnG=Search
Also, update your Java to the current version and clean out the old Java Console Extensions. See:

Facebook and Slacker no longer working with Firefox. Still work with Explorer. Until a week ago problem did not exist.

I am for about one week not able to input information on Facebook. Also the Facebook page appears in a huge font. Regarding Slacker I do not see any available online radio stations. Until about a week ago everything worked fine. At present I can work with Internet Explorer, but at present can no longer work with Firefox.

No longer works in firefox

why does my Adobe acrobat no longer work in firefox?

Hi lynettec,
When you say Acrobat doesn't work in Firefox, do you mean that you can't view PDF files in the Firefox browser? If so, please see View PDF files in Firefox without downloading them | Firefox Help
If you're referring to the Acrobat online services, they are supported in Firefox, so I'd would need a little more information about what's happening to get to the bottom of the problem.
Best,
Sara

Flash no longer working on Firefox after update

Moments ago I installed the Flash update after it came up on my screen asking to update, after doing so Flash is no longer working on Firefox, it works fine on other browsers. I cant view videos, look at flash objects etc. It was working perfectly fine before up untill the update. Anybody know how to resolve or fix this issue?

Dear Chris:
Yes, turning off Protected Mode indeed solves the problem!
Specifically, we today (June 9, 2012) installed the new Adobe Flash v. 11.3.300.257 on several Windows 7 PC's, all running Firefox v. 14 (Beta), and none of the Firefox installations would confirm that the installation was performed successfully. For example, the Adobe Flast test/about site, https://www.adobe.com/software/flash/about, would not work. And, likewise, YouTube videos and other Flash-encoded videos did not work either.
So, we tried your suggestion to disable the new Protected Mode, and it worked. That is, every single machine on which Flash did not work in Firefox now functions perfectly. So this conclusively demonstrates that there indeed is some kind of bug in the implementation of Protected Mode.
Can you please let me and the other Adobe users know when this is fixed. Thanks.
Also, could you likewise let us know the risks of turning of Protected Mode (although we really don't have any choice, as Flash will not work on Firefox with PM turned on).
Thank you. Much appreciated.
Kind regards,

Download Pull-Down Menu in Web App Olive ActivePaper Daily 4.0 No Longer "Works" in Firefox 10

I have a paid subscription to the online edition (aka "e-edition") of the Raleigh News & Observer, http://www.newsobserver.com/. In Firefox 10, I am no longer able to download the pdf of the paper; the download pull-down menu in web app "Olive ActivePaper Daily 4.0" no longer "works" in Firefox 10 on Win XP or Win 7. This was not a problem in Firefox 9 and earlier. The pull-down menu continues to "work" in IE8. A valid username & password is required to do the download. The ''only ''change made to my Windows XP system was the upgrade from Firefox 9 to Firefox 10.

The thread "Keynote Cancelled Shutdown: how do I troubleshoot?" has recently posted a possible solution but is there an explanation or a fix planned?

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).

Parallax no longer works in Firefox 16+

I created a Parallax ( scrolling interactive images in layers which tells a story) about 10 months ago or so, it works in every browser and at that time it worked in firefox 10-ish. I just saw today that it no longer works in Firefox 17 or 16, it doesn't scroll at all. The Parallax is in an iframe container ( not sure if that matters ) and it looks like the iframe has been squashed in height.
Thanks,
Sam

Yes it will break. Don't swap one for the other; use everything for now to cover your bases
*-moz-transform
*webkit-transform
*transform
So older Firefox will see -moz-transform, Chrome and Safari will see webkit-transform and new Firefox will see transform. When webkit changes then Chrome and Safari will see transform instead of webkit-transform. Then one day in the future you'll be able to remove the prefixed versions and just use transform.
Make sense?

Java 7 Update 11 Not Working with Firefox

For me, the problems described in the thread "Java 7 Update 10 Not Working with Firefox? " Java 7 Update 10 Not Working with Firefox?
are continuing with Java 7 Update 11.
Windows 7 64 bit
Firefox 18
The problem is that "Java(TM) Platform" is missing from the plug-in list.
I've uninstalled Java 7 Update 11 and reinstalled Java Update 9 which correctly installs the plugin and restores Java functionality which was broken immediately upon installing both Java 10 & 11.

So why not using Ju11 ? You can workaround the issue. It would sucks but still be safer than using Ju9.
Also ask Mozilla forums if Firefox has options where to search for plugins.
Or try 64-bit Firefox.As I explained in both threads ...
Java 7 Update 10 Not Working with Firefox?
Java 7 Update 11 Not Working with Firefox
... neither jre7u10 nor jre7u11 are working ... and they are BOTH broken with the same problem ... "Java(TM) Platform" pliugin is missing from the plug-in list. It cannot be enabled, because it simply is NOT there. A suggestion was made the jre7u12 will be the "fix" for this issue ... so I installed the Update 12 Preview and it sis ALSO broken, no "Java(TM) Platform" in the plug-in list.
The ONLY Java version that actually works for me is jre7u9.
As far as installing Firefox 64bit ... I see no future in installing a browser that has been discontinued.

Even though Mozilla relented due to backlash, I continued development will be a somewhat low priority.

RoboForm Lite no longer works for Firefox 17 windows 7 and server 2008r2

Greetings,
RoboForm Lite no longer works for Firefox 17 windows 7 and server 2008r2 I tried to reinstall but none of the tabs function . Thank you for your assistance

'''roboform_firefox:'''
The original poster (OP) reported his/her OS as Windows 7 in the body of the question, therefore, your solution would be of no use to the OP. You can also see the OS for the system used by the OP to post the question to the right of the original question in this forum .
Additionally, using an old version of Firefox is ill-advised as old versions contain uncorrected security vulnerabilities. Roboform has been very good lately in keeping their products updated for new Firefox releases and any problems with their products should be reported to them so that they can address any issues and release an update if needed.

I have the latest version of firefox and it is running under win 7 pro.
it was working great since I installed it 3 weeks ago and I use it every day.
the error reads:

Since installing Flash update today, Flash no longer works on FireFox (works fine on IE)

As prompted, Adobe Flash update was installed today. Since installing , Flash no longer works with FireFox (works ok with IE);

Hi guys - for me this helped.
Close Firefox - open Internet Explorer - got to the Adobe Flash Player Site:
http://get.adobe.com/de/flashplayer/
In IE you can see there is the 64-bit version - (in Firefox there was just the 32-bit version) - got to: (others)
http://get.adobe.com/de/flashplayer/otherversions/
choose your system and version
download it via internet explorer and install the adobe flash player
restart firefox and it should work.
helped me after wasting one day of my life to find a solution, alle sites work just fine now.
hope this helps.

Nofocus script no longer works in firefox 5

Does anyone know why the "nofocus" script is no longer working in Firefox 5?
I got sick of Yahoo hijacking my cursor, so I did some looking and found a script (below), which is added to your user.js file. It worked just fine in FF4 and 4.1. When I updated to 5, however, it stopped. Any ideas?
Here's the script:
user_pref("capability.policy.policynames", "nofocus");
user_pref("capability.policy.nofocus.sites", "http://www.yahoo.com/");
user_pref("capability.policy.nofocus.HTMLInputElement.focus", "noAccess");

Looks that CAPS are no longer supported for DOM Events like that.
