FF doesn't recognize printer after installing java

I am running FF3.6.12 and everything was working. I had to download java so that I could access an online auction and then FF quit recognizing the printer that had been working prior to java. FF tells me I need to load a printer and I follow the screens to load my network printer and when I print the test page it works. I then try to print ion FF and up pops the box telling me I need to load a printer and asking me to go through the same process again......

You can try "Reset all user preferences to Firefox defaults" on the [[Safe mode]] start window.
* http://kb.mozillazine.org/Resetting_preferences
Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.

Why is it my macbook air will not print coupons after installing java?

why is it i cannot print coupons from my macbook air after installing java?

Hi JDP86,
Thanks for using Apple Support Communities.
If your printer is wireless-capable, you should first add the printer to your network. Use the printer's control panel, or temporarily connect the printer to your Mac via USB.

Unable to Print After Installing Adobe Acrobat Reader Upgrades.

. What software version of Abobe Acrobat Reader should be used for an HP PhotoSmart Plus printer? I currently have Adobe version 9.3 installed. I receive pop-up notices to install new Adobe Acrobat Reader software upgrades. I have installed the software upgrades and then my HP PhotoSmart Plus printer was unoperational. I deleted the Adobe software upgrades and my HP PhotoSmart Plus printer began to operate. I contacted HP technical support and was told there is no compatibility issues between Adobe Acrobat Reader and HP All-in-One Products. It might be a problem with the specific Adobe software upgrades. HP requested that I contact Adobe support for problem resolution. Has this problem ever happened to you? Any problem resolutions would be appreciated.

After installing Java 7 version 21 Safari no longer sees Java

The Computer is running 10.7.5 fully patched. After installing Java 7, version 21 from Oracle Java and VPN no longer work. Everything looks OK in the Oracle Java control panel and Safari does not have Java plug-ins disabled. Removing and reinstalling Java have not solved the problem. Ive also went to http://javatester.org/version.html done the Java tests. However it does not even show that the Java plug-in is active or for that matter inactive. Any idea's other then not to use Java that I must use for VPN and WebEx?

I have the same problem. Called apple today since this seems to be a problem with Safari. Apple wanted 63 USD to help me solve this. Been trying to figure it out for a couple of days now but no luck.

After upgrading to Mac OS Lion, even after installing Java manually, some web pages don't download and appear blank whereas Firefox works

After upgrading to Mac OS Lion, even after installing Java manually, some web pages don't download and appear blank whereas Firefox and Opera work. Can someone help?

Might be a third party Safari addon that was compatible with Snow Leopard but not Lion that's preventing pages to load. That add on may not have any effect on the other browsers, just Safari.
Read here > Safari: Unsupported third-party add-ons may cause Safari to unexpectedly quit or have performance issues
Also, if you have Little Snitch or Peer Guardian or anti virus sofware installed on your Mac, that might prevent pages to load also.

Unable to print after installing the new Quicktime upgrade

I can not print to my Epson printer after installing the new Quicktime upgrade on my PowerBook G4 (1.67 GHz, OS X Version 10.4.11). I have re-installed the driver from Epson (several times), and have safe booted and reset my permissions but it will not print. My printer is a Epson Stylus Photo R1800. When I print, it just gives me this message... "Looking for Printer 'EPSON Stylus Photo R1800' "

Latigna, welcome to Apple Discussions.
Here's a similar problem on the same Epson printer. http://discussions.apple.com/message.jspa?messageID=8928421

HT5717 Application crashes after installing Java 1.6.0_51

Our Electronic Medical Records application now crashes upon start up after installing Java 1.6.0_51.
How do I back it out so I can re-install the previous Java version that works with out software?
And I am referring to the runtime to run .jar files.

I resolved the problem by going to the eclipse project properties page and removing the 1.6 jre library in "Java Build Path" (Libraries tab). I then clicked on "Add Library..." and selected "JRE System Library." I then clicked on "Installed JREs ..." and eclipse gave me an error to the effect that it was deleting the JRE because it was missing. I clicked OK to the warning. On the "Installed JREs" page I clicked "Search..." then navigated to the /System/Library/Frameworks/JavaVM.framework/Versions/1.6 directory and chose it. I was then able to select JVM 1.6 and life was good.

After installing "Java for OS X 2013-004" update, Java apps don't work anymore as expected

After installing "Java for OS X 2013-004" update, Java apps don't work anymore as expected.
Windows of Swing apps don't display all GUI elements.
After replacing System/Library/Java from a Time MAchine Backup, everything works normal again.
Is this update corrupted?

"avoid using Java in a web browser at all,..."
Good advice.
"...old Java apps/applets that aren't written to modern specs ..."
The stand-alone Java Swing applications, that don't display their GUI elements after installing this update, have been written according to modern standards. With Oracle Java7, and with Java6 from Apple prior to this update, they run absolutely flawlessly.
This is absolutely Apple's fault.

My mini (late 2012) 2.3 GHz i7 with 16 GB, not loading images after installing Java that I need to run FileMaker Server 12.

I'm running yosemite on a mini (late 2012) 2.3 GHz i7 with 16 GB, my problem is that after installing Java that I need in order to run FileMaker Server 12, apps like Safari, Mail or even App Store, stop working properly, the mayor problem is that NO images load and Safari start saying that the pages are not loading because the connection with the server stop working. The only way to fix it is to re-start the computer.
Any idea to resolve the problem.

Firefox doesn't recognize FLASH after update, no matter what. Also says to update plugins but there are none to update listed?

I have downloaded & re-downloaded FLASH, but after I updated my Firefox to 22.0 it no longer recognizes FLASH is installed on my computer. It also keep telling me "Some plugins required by this page have been blocked for your protection." When I check the plugins, the 3 listed are up to date, and the other 3 are marked "research" - which doesn't allow you to update them. I cannot discern that any of those are what is being blocked. When I click on Details, it brings me to a list of "Modules bloqués" and it's all listed in French...which would be great if spoke French or lived in France, but alas California is in the USA. My Java is updated, enabled & not blocked in any way. My Shockwave Flash is disabled & it will not give me the option to Enable it; I also cannot find a way to reinstall it or find a plugin to help me. !@#$%! So frustrating that this new "update" is useless. I hate 22.0.
What do I do now?

Your System Details List shows that some plugins are blocklisted and Flash is included:
# plugin.blocklisted.flash: True
# plugin.blocklisted.java: True
# plugin.blocklisted.nppdf: True
Which version of the Flash plugin do you have installed if you check that in Firefox/Tools > Add-ons > > Plugins?
You will have to update Flash to make it work.
You can find the latest Flash player versions for Firefox on this page.

My hp4530 will not print after installing Yosemite

After installing Yosemite my printer will not connect because it is not "found" by my macbook pro. I re-installed the driver, but that hasn't worked. What else can I do? I've restarted, unplugged . . . all the obvious things haven't been successful.

Hi Bella,

After installing Java 6 update 11 for OSX 10.6, unable to open .jnlp files.

Appears to download application then quits without an error message. When clicking on the .jnlp file again, nothing happens. I can go into java preferences and remove the application from the cache, but it does the same thing, redownloads the application then doesn't open it.

After doing some research, I found a plugin for Google Chrome that will put current page you are on into an Internet Explorer wrapper with Java 6 installed in it. Its called Rndr and I have tested it on OSX 10.8 and 10.6.8 and it appears to launch any java plugin or .jnlp webstart app in the browser itself.

Java is notoriously responsible for many vulnerabilities, if you must run it then these are the instructions:
Turning on Java
Why will Applets not run after getting Java through Apple Software Update?
Apple disables the Java plug-in and Webstart applications when the Java update is done using Software Update. Also, if the Java plug-in detects that no applets have been run for an extended period of time it will again disable the Java plug-in.
To enable the Java plug-in
Go to Finder > Applications > Utilities > Java Preferences.
In the Java Preferences window check the box for Enable Applet plug-in and Webstart applications.
Installing and updating Java
I DO NOT have Mac version 10.7.3 (Lion) or higher. How do I get Java for other Mac versions?
For Java versions 6 and below, Apple supplies their own version of Java. Use the Software Update feature (available on the Apple menu) to check that you have the most up-to-date version of Apple's Java for your Mac.
I DO have Mac version 10.7.3 (Lion) or higher.
Users of Lion Mac OS X 10.7.1 and 10.7.2 should upgrade to 10.7.3 or later versions via Software Update, so you can get the latest Java 7 version from Oracle.
Download page here:
https://www.java.com/en/download/manual.jsp#mac
Why is Java 7 available only for Mac OS X 10.7.3 and above?
The Java Runtime depends on the availability of an Application programming interface (API). Some of the API were added in Mac OS X 10.7.3. Apple has no plans to make those API available on older versions of the Mac OS.
