About Flash and Java in OS X Lion

Hi.
I see that Apple released two different updates to remove flashback trojan. I have read that it depends on your installation and if you have Java installed or not.
I thought that Java was included in the OS, wasn't it?
Lion doesn't have it and you have to install by yourself?
Flash should be downloaded from Adobe's site, but what about Java? It's need to install it? Should be installed? What should be safer?
So, all new computers doesn't include neither Flash neither Java, or is it something related to a clean install?
Thank you!

So, Lion, anyway you get it, won't have Java intalled, right? It doesn't matter if you get a new Mac, if you upgrade from 10.6.8, or if you clean install Lion?
Correct.
No new Mac will bring Java anymore? It's due to security?
Well, sort of. It's also due to an agreement with Oracle that they would be responsible for Java 7 and higher, but they weren't quite ready when Lion was released (it's available now).
And what about Java preferences.app? If I try to use it, it ask me to install a Java enviroment...it's just a normal thing, right?
Yes, it's normal.
Is it really more safe to have it uninstalled?
Not today, but there are known vulnerabilities in the current version that someone might figure out how to exploit in the same manner as Flashback and a couple of other malware developers did with the last version.
What can I miss if I don't install it?
You will be told if you need it. There are a few applications written either partially or completely in Java (CrashPlan is probably the most popular). Some web sites still use it. A few banks and someone said they could not get into their AT&T account without it, but I've not had any problems. I read some statistics that slightly over 5,000 of the top 1 million web sites contained Java code, so not very many.

  • Question about Flash and Java in OS X 10.6.6...

    I am about to get a MacBook Pro this weekend (after having numerous problems with Windows and getting it to work with my hardware - that led to me thinking of buying a Mac. Nothing to do with viruses actually ;))
    Anyhow - does Snow Leopard 10.6.6 ship with Adobe Flash, or do I need to install Flash myself? I'm not too concerned with doing that (I prefer to as I know I'm installing the latest version - just like Windows!)
    Secondly - does Apple provide updates for Java as well? Do I need to install Java myself, or does Snow Leopard ship with Java pre-installed too?
    Lastly - this is just your opinions, but which out of Safari, Chrome, Opera and FireFox do you consider to be the safest (and securest) browser for Mac?
    Thanks,
    Xavier12.

    It is best to follow Adobe's instructions for updating its software, which varies by the product & versions involved. This usually works well but Adobe is one of those companies big enough to play by its own rules, sometimes ignoring Apple's developer guidelines or inventing its own API's instead of using the Apple provided ones that do the same thing, so there is a small chance things won't go as expected even when you follow the instructions to the letter.
    If this happens it is best to seek advice on a product by product, version by version basis.

  • 32-bit flash and java plugins freeze firefox and gnome on 64-bit linux

    I have installed FC13 64-bit and am running 32-bit firefox 3.6.8 so that I can run flash plugin.
    When I start 32-bit firefox 3.6.8 and go to site with flash or java applet, firefox locks up my gnome desktop necessitating a reboot of my computer.
    Firefox 3.6.8 32-bit
    Flash 10.1r82
    Java jdk 1.6.0_15 32-bit
    I have used a similar configuration on 32-bit FC13 with 32-bit Firefox 3.6.8 and everything works fine. No lockups.

    Hi!
    I finally solved this problem. The 32-bit libflashplugin required a 32-bit libcurl library that is not installed by default on 64-bit linux systems (at least not on Fedora). Once I installed 32-bit libcurl libs, flash and java plugins starting magically working.
    In my opinion, 64-bit Fedora has done a poor job with 32-bit compatibility viz a viz 32-bit libs. I will submit an improvement ticket to Fedora folks about installing more 32-bit libs on 64-bit distros.

  • Safari acts like Flash and Java are not installed, even though they are

    Even though I have the latest versions installed, websites viewed in Safari tell me that I need Flash and/or Java. I have searched the forums and tried every suggestion, with no fix:
    • Uninstall and re-install Flash
    • Re-install Java
    • Delete the Flash player cache (~ > Library > Caches > Adobe > Flash Player)
    • Repair permissions on the hard drive
    Flash and Java were both working fine until the 10.6.5 upgrade. Flash and Java both work in Firefox and Chrome on the same machine. (Everything is the latest version.)
    If anyone has a solution that will actually restore the use of Flash (don't really care about Java), that would be awesome! Thanks in advance for your help!

    Hi,
    Install the 10.6.5 Combo Update.
    Then launch Disk Utility. Applications / Utilities then repair disk permissions.

  • I continually get a Java error. I've uninstalled and reinstalled firefox and nothing has helped. I've updated flash and Java.

    I have used Firefox as my default browser for many years. I've recently started getting a Java error message. It pops up continually. I have updated flash and java. I have uninstalled and re-installed Firefox and nothing has helped. I have had to start using Chrome instead of Firefox which I don't care for but I don't have the java error with Chrome. How do I fix this problem? The error reads as follows:
    Java Script Application
    Error: syntax error

    Your '''JavaScript''' error has nothing to do with the Java plugin . It is likely caused by an added extension (the earlier forum threads [/questions/944619] and [/questions/943088] mention disabling or updating the Social Fixer extension will resolve the problem).
    You can read this article for help troubleshooting your extensions: [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]

  • Help Please. OS 10.5, Safari 5.0.6, Flash and Java

    Hi.
    I am very frustrated right now.  A few days ago, I upgraded my MacPro to OS 10.5 .  Everything seemed to be working fine until all of a sudden a fe days ago.
    Now Flash and Java don't work.
    I get an error message saying missing plug-in.  So I went to the adobe page to download the latest version.  The only thing that would happen on that page is the banner in the middle frame disappeared and nothing would download using Safari.  I opened Firefox and it was able to download it.  I  ran the uninstaller, then installed the newests version, 10.??? (Newest on allowed on my computer)
    I rebooted the computer to be safe and opened Safari and still no flash, same message.  It works fine in Firefox and Seamonkey, just not safari.  I checked for  plug-ins and it doesn't show up.   It IS in the OS preference, but there is nothing I can see to do.
    Flash makes way to many things work to just ignore it.  Please help.
    I have repeated this step more than once to no avail.   
    Secondly, Java.  Java is not installed anymore.  It WAS and I was having a problem with the window opening and staying open.  I adjusted a setting not to open the window, then it stopped completely.   I backtracked and undid the do not open window and still doesn't work.
    I found a Java testing page and this is what I was given - "The page “Java Tester - Is Java Enabled?” attempted to load Java content, but Java is unavailable or not installed."
    I am now downloading Java again from the apple page, 1.6.0_33.  However, one poster said not to use it at all.  It's difficult to do many things with no Java at all.
    Please advise.
    Thank you in advance for your help!

    Now, follow my standard upgrading advice:
    Get a bootable, external HD (preferably FireWire, since it's 40-50% faster than USB 2 and designed for data transfers), make a bootable backup/clone before updating/upgrading, and ensure that it's bootable and works like the original. That allows you to revert to the previous good state without having to reinstall or reset anything. See these for details:

    http://www.thexlab.com/faqs/installswupdates.html
    http://www.thexlab.com/faqs/backuprecovery.html
    If you only have a Time Machine backup, ensure that you can reliably restore it to another disk/volume/partition before updating/upgrading.

  • What is the minimum browser requirements for Captivate 5? (Specifically Flash and Java)

    I create a Captivate from and upload it to our LMS. When employees access the course it takes a long time for it to load. My IT department is asking what is the minimum browser requirements for Captivate 5? Specifically Flash and Java. This is occuring on PC's and a Citrix environment.

    Hi there,
    Thanks for reaching Adobe Community. Please accept my apologies for the same.
    There is nothing in specific. When you say it takes a long time, do you mean on the LMS or locally as well?
    Try updaing the Flash Player.
    You can download the Falsh Player Versions from the below link:
    http://www.adobe.com/support/flashplayer/downloads.html
    Which browser you are using?
    Also what objects you have in your project?
    Does it have widgets or heavier graphics?
    Also are you using any particular preloader? Have you tried using the default.swf preloader?
    Thanks!

  • How do I enable flash and java on firefox23 as I have the latest versions installed yet the plugin page shows "disabled" with no option to enable

    I have updated to Firefox 23 and it disabled my Java and Flash plugins. I then updated these to Flash 11.8.800.94 and Java to Version 7 Update 25. Now these are showing up on the plug in page but are showing "disabled" with no option to enable. How do I enable them to view content on the web.

    Thanks Philipp but i have already done that and the content started working...
    However, when i closed and restarted the browser it returned back to the same settings...
    I dont think that should happen, but anyway thank you for the solution. At least I can use it by resetting the values if need be
    Appreciate your help

  • Issue with usb flash and removable hard drives in Lion. (also an install tip)

    Having an issue with my usb flash and removable hard drives.  I plug them in and Lion does not display all my files/folders, I take it out and plug it into my snow leopard machine and all the files/folders are there, does anyone have this issue?
    It does it on my macbook pro which was a snow leopard upgrade to Lion and it does it on my macbook which was a clean install of Lion via a bootable flash drive.
    The computers both work great in all other aspects, so there were no errors on installation. It's plain and simple, some files/folders are not showing up that are present on the drives and viewable on all other non-lion OS's mac and PC.
    Also a word on installs, I highly suggest doing a clean install (delete and reformat drive them install Lion vs a snow leopard ugrade) my machine that was a clean install (macbook) runs 50% faster and smoother than the upgraded one (macbook pro).

    Yes, you can use your backup disk drives in the manner you describe, but Apple provides conflicting information on the subject.
    From Mac Basics: Time Machine
    Time Machine can’t backup to an external drive that's connected to an AirPort Extreme, Time Capsule, or a drive formatted for Microsoft Windows ...
    From Time Machine doesn't back up to AirPort Extreme AirPort Disks
    Time Machine in Mac OS X v10.5 or later can be used to back up to many kinds of Mac OS Extended-formatted drives, but you cannot choose an AirPort Extreme 802.11n's AirPort Disk as a Time Machine backup volume.
    However, you can choose Time Capsule AirPort Disks or internal disks as a Time Machine backup volume.
    They have yet to resolve this discrepancy.
    All other available technical details regarding Time Machine's use seem to indicate that a USB HD connected to Time Capsule should meet Time Machine's requirements. For what it's worth I have been using an external HDD connected to the Time Capsule's USB port and it seems to function just fine.

  • Can we built connection between flash and JAVA?

    Hello i m a flash developer. I need a solution to improt java class in flash.
    Is there any solution to connect java and flash. Plz reply ASAP.

    Hi,
    I have created a java class in EJB now want to import
    it in Flash and want to use the object of the class.
    Can u give me any program to do this?Huh?
    What do you mean?
    Why do you want to import an EJB into your Flash app?
    It's impossible to do such a thing you know.
    Also EJBs are not meant to execute on any client end.
    Those are server end beasts.
    From the Flash application you should call remotely the EJB through a servlet.

  • Flash and java games not working

    hi,
    when i try to play online games that uses flash or java, they wont load, flash games just show the red F, IVE TRIED DOWNLOADING FLASH FROM ADOBE, but that didnt work, ive tried updating my software to the latest version, that didnt work either. ive also tried the update app, but none were found.
    the phone is a nokia 5800 music express,
    any help would be apppriciated,
    many thanks ,
    wayne.

    The flash app you're trying to play has to support Flash Lite, otherwise it won't work. Flash content has become pretty demanding in terms of hardware required to run it smoothly, or run it at all for that matter...
    The question here is, did the content you're trying to view/play work before, and on which mobile phone? If you never had success in using the same flash/java apps/applets on any phone, then trying to solve your problem is feasible. If not - most likely you've run into a demanding app(let) which simply needs the full Java RE or Flash, and it won't work with mobile Java or Flash Lite.
    Careful what you wish for... You just might get it.

  • App store and Java broken on Mountain Lion?

    Hi all, so I just purchased a brand new 13" Macbook Pro, the first thing i did was install Mountain Lion on it, (it came from the factory with Lion) so i have no time machine backups to revert to. Here are my problems 1.) I can't download anything from the appstore, no matter how large or small of an app. 2.) Java will not download, when I open java preferences it prompts a dowload which after reaching about 15 mb it will say the download failed because the file was corrupted. The same thing happens when I try and manually initiate the download through Terminal. I spoke with several Apple reps and they all said that I would have to reinstall Mountain Lion (as far as I can tell there is no way to do this without a backup). So is there a way to fix this without reinstalling Mountain Lion? If not how do i reinstall. Any help is greatly appreciated
    Thanks

    I can't download anything from the appstore, no matter how large or small of an app.
    Open System Preferences > Security & Privacy > Security > General
    Click the gold padlock icon to make changes. You may be prompted for your admin password.
    Select:  Mac App Store and indentified developers
    I spoke with several Apple reps and they all said that I would have to reinstall Mountain Lion (as far as I can tell there is no way to do this without a backup).
    You can reinstall OS X using Mountain Lion Recovery but it shouldn't be necessary.

  • Flash and Java constantly do not load/work in Firefox, despite having the updated versions of all three programs. Why?

    Java and Flash on web pages do not work, and I have to switch browsers in order to use certain pages. I would rather not do that if Firefox could handle Java and Flash applications. Sometimes, my browser just crashes altogether when trying to use a Java or Flash application.

    I am not sure how to link these discussions, so below I am pasting the post that helped me. And here is the link:

    This is not a problem specific to Lion, but most recent OS X versions. Regularly I receive email formatted as HTML, which includes JPEG images embedded within them. These images are technically attachments, and as such, Mail.app displays them as a placeholder. Other mail apps will display these images inline, regardless of them being an attachment, remote image or otherwise.
    How can I make these images load automatically?
    MacBook, Unibody, Mac OS X (10.7), 750GB, 7200RPM WD HDD, 4GB RAM 
    This solved my question by louse101  on Jul 26, 2011 3:47 AM 
    No-one replied, but I found a solution on another board. Run Terminal (do a Spotlight search if you don't know where to find this), and type:
    defaults write com.apple.mail DisableInlineAttachmentViewing -bool false
    This will force Mail not to disable inline attachment viewing. Obviously, to reverse this, simple replace 'false' at the end with 'true'.
