I installed Firefox 4 on my new computer and am getting a banner on some web pages stating "Additional plug ins are required to display all the media on this page - I haven't had this problem until today; I have been using Firefox on my Macs for years.

I just bought a new MacBookPro to replace my 3 year old MBP. I was not receiving the banner when I was on my old Mac running Firefox 3.6.16.
The yellow banner seems to appear randomly. I got it when I went to https://artistsnetwork.tv/e-myvideos.aspx and https://bit.ly.com but not when I went to Hootsuite, Twitter or textbroker.com.
There is an "Install missing plugins" button on the right side, but I'm afraid to click on it since I don't understand what might happen to my new computer.

  • Additional plugins are required to display all the media on this page

    I realize plugins are not part of Mozilla, but Mozilla is giving me a looping error message that something is missing when I don't see at all that anything is.
    I receive this message when I am trying to play an audio file for transcription. "Additional plugins are required to display all the media on this page". I know the program uses QuickTime, and that is up-to-date, but not sure what other plugins it would need.
    There is an "Install Missing Plugins" button. When I click that, a Plugin Finder Service window opens and the message "No suitable plugins were found".

    Do you have the Windows Media Player plugin?

  • Additional plug ins are required to display media but when I click the tab to install missing plugins why does it tell me there ar no suitable plugins to install.

    When I am on Amazon.com, a message appears that additional plug ins are required but when I click on button to "install missing" plug-ins, it tells me there are no suitable plugins. I have downloaded "FreePriceAlerts" and a bar usually appears and I believe whatever plug-in is missing is preventing this from showing. When I use IE I have no problem.

    Can you post a link to the page where you have that problem?

  • How do I prevent the yellow bar from appearing across the top of Hotmail emails that says, "Additional plugins are required to display all the media on this page." I DO NOT want plugin. How do I get Firefox to stop sending message?

    Note: I did try to install the plugin just to see what would happen. When I clicked on "Install Missing Plugin" the next page said plugin could not be found---install manually. I clicked on manual install button and was directed to Adobe Flash Player - I already have current version of AFP installed.

  • I have been using Adobe Photoshop Elements 11 for two years. I got a new printer and installed it although I did not remove my old printer from my computer. I used this program and my new printer for quite a few months, but today I deleted my old printer

    I have been using Adobe Photoshop Elements 11 for along time now. When I first used the program I had a different printer than I have now. Although I changed printers I never removed the software from my old one. Now this was never a problem until today. When I choose a printer I still had option to use the old one but always chose my new HP Envy 5530 and Adobe never had a problem printing from that new printer. However today I decided to remove my old printer from my computer and now my Adobe cannot find my new printer.  How can I make it find the HP printer?

    Try this --
    Go to the bottom of the link I gave you, and you will see
    click that link and then click the chat button to talk to an Adobe agent

  • I seriously don't know what caused this to start being a problem until today it worked fine, but I added an exception for popups full question in DETAILS

    is there anyway to allow Firefox to allow pop ups from this 1 page of Facebook / well this 1 game https://apps.facebook.com/vampiresdarkside/ and not the entire pan in the Ass Pop up happy site, I cant see any sense in allowing popups from all
    apps.facebook.com
    and when I try to add it as the exception should be your program edits it to be that crap above instead of the exception I entered specifically,
    apps.facebook.com/vampiresdarkside/
    I seriously don't know what caused this to start being a problem until today it worked fine, but I added an exception for popups from this one site in Chrome and Firefox decided it wouldn't allow it popups from this part of Facebook and no I am not allowing all the FB apps to have popups I never had to before
    apps.facebook.com/vampiresdarkside/
    have popups after adding the popup exception in chrome, and no I did nothing to Firefox but it is kinda asking me to switch to Opera or some other crap browser with it acting like this, I modified the exception in chrome and Firefox now wont allow the pop ups it always had up until chrome allowed them WTF

    Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> 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

    I have been using Lightroom 4.4 successfully for over 2 years.  Just tried to import some new photos after a vacation and the application crashes when I click "import" every time.  Tried restarting computer.  Version says it is up to date.
    How do I get formal support for this from Adobe?

    Thanks for the response.  The application was crashing.  A Windows message was displayed showing "Lightroom.exe has stopped working", "Windows can check online for a solution the problem.". Etc.
    I just launched Lightroom to check the exact message for this reply - and the Import worked.  It had failed dozens of times before. 

  • I have a mid2009 MacBook Pro for which I have been using a USB WD HD for Time Machine.  I'd like to get a wireless HD  and start a new Time Machine backup for this Mac and retire the 5  year old WD drive.  Can I start over?

    I have a mid2009 MacBook Pro running Mavericks for which I have been using a USB WD HD for Time Machine.  I'd like to get a wireless HD  and start a new Time Machine backup for this Mac and retire the 5  year old WD drive.  Can I start over?

    no archive/ backup is perfect, HD clones can be set to make incremental additions, same as time machine however, though they are more time involved in doing so.
    See the + and - of all data backup/ archives below and "spread it around".... or the "dont put your eggs all in one basket" philosophy.

    Data Storage Platforms; their Drawbacks & Advantages
    #1. Time Machine / Time Capsule
    Drawbacks:
    1. Time Machine is not bootable, if your internal drive fails, you cannot access files or boot from TM directly from the dead computer.
    2. Time machine is controlled by complex software, and while you can delve into the TM backup database for specific file(s) extraction, this is not ideal or desirable.
    3. Time machine can and does have the potential for many error codes in which data corruption can occur and your important backup files may not be saved correctly, at all, or even damaged. This extra link of failure in placing software between your data and its recovery is a point of risk and failure. A HD clone is not subject to these errors.
    4. Time machine mirrors your internal HD, in which cases of data corruption, this corruption can immediately spread to the backup as the two are linked. TM is perpetually connected (or often) to your computer, and corruption spread to corruption, without isolation, which TM lacks (usually), migrating errors or corruption is either automatic or extremely easy to unwittingly do.
    5. Time Machine does not keep endless copies of changed or deleted data, and you are often not notified when it deletes them; likewise you may accidently delete files off your computer and this accident is mirrored on TM.
    6. Restoring from TM is quite time intensive.
    7. TM is a backup and not a data archive, and therefore by definition a low-level security of vital/important data.
    8. TM working premise is a “black box” backup of OS, APPS, settings, and vital data that nearly 100% of users never verify until an emergency hits or their computers internal SSD or HD that is corrupt or dead and this is an extremely bad working premise on vital data.
    9. Given that data created and stored is growing exponentially, the fact that TM operates as a “store-it-all” backup nexus makes TM inherently incapable to easily backup massive amounts of data, nor is doing so a good idea.
    10. TM working premise is a backup of a users system and active working data, and NOT massive amounts of static data, yet most users never take this into consideration, making TM a high-risk locus of data “bloat”.
    11. In the case of Time Capsule, wifi data storage is a less than ideal premise given possible wireless data corruption.
    12. TM like all HD-based data is subject to ferromagnetic and mechanical failure.
    13. *Level-1 security of your vital data.
    Advantages:
    1. TM is very easy to use either in automatic mode or in 1-click backups.
    2. TM is a perfect novice level simplex backup single-layer security save against internal HD failure or corruption.
    3. TM can easily provide a seamless no-gap policy of active data that is often not easily capable in HD clones or HD archives (only if the user is lazy is making data saves).
    #2. HD archives
    Drawbacks:
    1. Like all HD-based data is subject to ferromagnetic and mechanical failure.
    2. Unless the user ritually copies working active data to HD external archives, then there is a time-gap of potential missing data; as such users must be proactive in archiving data that is being worked on or recently saved or created.
    Advantages:
    1. Fills the gap left in a week or 2-week-old HD clone, as an example.
    2. Simplex no-software data storage that is isolated and autonomous from the computer (in most cases).
    3. HD archives are the best idealized storage source for storing huge and multi-terabytes of data.
    4. Best-idealized 1st platform redundancy for data protection.
    5. *Perfect primary tier and level-2 security of your vital data.
    #3. HD clones (see below for full advantages / drawbacks)
    Drawbacks:
    1. HD clones can be incrementally updated to hourly or daily, however this is time consuming and HD clones are, often, a week or more old, in which case data between today and the most fresh HD clone can and would be lost (however this gap is filled by use of HD archives listed above or by a TM backup).
    2. Like all HD-based data is subject to ferromagnetic and mechanical failure.
    Advantages:
    1. HD clones are the best, quickest way to get back to 100% full operation in mere seconds.
    2. Once a HD clone is created, the creation software (Carbon Copy Cloner or SuperDuper) is no longer needed whatsoever, and unlike TM, which requires complex software for its operational transference of data, a HD clone is its own bootable entity.
    3. HD clones are unconnected and isolated from recent corruption.
    4. HD clones allow a “portable copy” of your computer that you can likewise connect to another same Mac and have all your APPS and data at hand, which is extremely useful.
    5. Rather than, as many users do, thinking of a HD clone as a “complimentary backup” to the use of TM, a HD clone is superior to TM both in ease of returning to 100% quickly, and its autonomous nature; while each has its place, TM can and does fill the gap in, say, a 2 week old clone. As an analogy, the HD clone itself is the brick wall of protection, whereas TM can be thought of as the mortar, which will fill any cracks in data on a week, 2-week, or 1-month old HD clone.
    6. Best-idealized 2nd platform redundancy for data protection, and 1st level for system restore of your computers internal HD. (Time machine being 2nd level for system restore of the computer’s internal HD).
    7. *Level-2 security of your vital data.
    HD cloning software options:
    1. SuperDuper HD cloning software APP (free)
    2. Carbon Copy Cloner APP (will copy the recovery partition as well)
    3. Disk utility HD bootable clone.
    #4. Online archives
    Drawbacks:
    1. Subject to server failure or due to non-payment of your hosting account, it can be suspended.
    2. Subject, due to lack of security on your part, to being attacked and hacked/erased.
    Advantages:
    1. In case of house fire, etc. your data is safe.
    2. In travels, and propagating files to friends and likewise, a mere link by email is all that is needed and no large media needs to be sent across the net.
    3. Online archives are the perfect and best-idealized 3rd platform redundancy for data protection.
    4. Supremely useful in data isolation from backups and local archives in being online and offsite for long-distance security in isolation.
    5. *Level-1.5 security of your vital data.
    #5. DVD professional archival media
    Drawbacks:
    1. DVD single-layer disks are limited to 4.7Gigabytes of data.
    2. DVD media are, given rough handling, prone to scratches and light-degradation if not stored correctly.
    Advantages:
    1. Archival DVD professional blank media is rated for in excess of 100+ years.
    2. DVD is not subject to mechanical breakdown.
    3. DVD archival media is not subject to ferromagnetic degradation.
    4. DVD archival media correctly sleeved and stored is currently a supreme storage method of archiving vital data.
    5. DVD media is once written and therefore free of data corruption if the write is correct.
    6. DVD media is the perfect ideal for “freezing” and isolating old copies of data for reference in case newer generations of data become corrupted and an older copy is needed to revert to.
    7. Best-idealized 4th platform redundancy for data protection.
    8. *Level-3 (highest) security of your vital data. 
    [*Level-4 data security under development as once-written metallic plates and synthetic sapphire and likewise ultra-long-term data storage]
    #6. Cloud based storage
    Drawbacks:
    1. Cloud storage can only be quasi-possessed.
    2. No genuine true security and privacy of data.
    3. Should never be considered for vital data storage or especially long-term.
    4. *Level-0 security of your vital data. 
    Advantages:
    1. Quick, easy and cheap storage location for simplex files for transfer to keep on hand and yet off the computer.
    2. Easy source for small-file data sharing.

  • I have been using firefox successfully for some time but now it will not open. I deleted firefox and re installed it but it still will not open. What happened??????

    I have been using firefox for over a year with no problems. All of a sudden it has quit opening. I thought it might be something in my computer so I uninstalled firefox and reinstalled it from your web site. It still will not open. What do I do now???????

    A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
