Can't get add ons, addons video won't run 'no video support format'

I was trying to download a coupon printer add on, but it didn't download. Trouble shooting video wouldn't play because it said 'no video support format'.

Note that an 'no video support format' error is usually caused by web pages that use the HTML5 media player to play a video and either no suitable format is available or the server isn't configured properly and doesn't send the file with a supported MIME type.

You could try to see if you can open the video in a new tab via the right-click context menu (View Video).

  • CAN'T GET ADD ONS. XPINSTALL.ENABLED DOES NOT SHOW UP IN ABOUT:CONFIG LIST.

    ADD ON S TAB SHOWS LOADING, BUT NEVER SHOWS A LIST OF ADD ON S. LOOKED FOR "XPINSTALL.ENABLED" IN "ABOUT:CONFIG" SO I COULD CHANGE IT, BUT IT IS NOT THERE.

    If the Get Extensions tab in about:addons isn't working then you can go to the Add-ons website and search for extensions yourself.
    *https://addons.mozilla.org/firefox/
    The xpinstall.enabled pref default to true when absent and doesn't have any real effect in preventing to obtain and install extensions unless locked to false.

  • Can i change the link attached to "Get Add-ons button" on the About:Addons page?

    Hi:
    on the about:Addons page, on the left hand side, top there is this nice option/?button "Get Add-ons link"
    Is there a way to change where I am navigated to when I click it?
    currently takes me to this overall page, from about:addons
    I want to go directly to:
    https://addons.mozilla.org/en-US/firefox/extensions/
    to get there, i have to scroll down the about:addons page, and click.. clunky for me ...
    thankyou

    Put the preferences that you change in a '''user.js''' file, instead of doing that change in about:config, and backup that file. <br />

    Then when you create a new Profile, copy that user.js file into the new Profile folder.

  • Can't update add-ons, install toolbars or new add-ons, get desktop shortcut icons to work, delete desktop shortcut icons, or uninstall Firefox! Help!

    I have Firefox 3.6.3 running on a Toshiba Satellit laptop with Windows XP. I can't update add-ons, install google and yahoo toolbars, get any of the 3 desktop shortcuts to work or delete them, nor uninstall Firefox to try and start over. What a piece of crap! How can I wake up from this nightmare?
    == This happened ==
    Every time Firefox opened
    == Every time I try to use Firefox.

    Create a new profile as a test to check if your current profile is causing the problems
    See [[Basic Troubleshooting|#Make_a_new_profile|Basic Troubleshooting: Make a new profile]]
    There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins"
    If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

  • I have the newest version of Firefox 15.01 and I wanted to add some add-ons but they won't open up.

    I have firefox 15.0.1 and my addons won't load. I wanted to add something new and all it does is keep working like it's busy trying to open or load them but nothing happens. It's been like that for over 4 days. I can't add any new add ons at all. What's going on?? I

    Do you mean the Get Add-ons tab on the about:addons (Firefox > Add-ons) page?
    If that page isn't working then you can visit the Mozilla Ad-ons site directly.

  • How can I get the best quality video on YouTube?

    I tried what you posted from another poster, Steve, but had a problem at step 2, the part in red.
    2. Import this AVI file into Windows MovieMaker, place the file on MovieMaker's timeline and Publish (to your hard drive) a 
    WMV, dvd-quality (4:3 size) PAL 3,0 M.
    When I click Publish, the only option I get is "YouTube" and "Get Add Ons".
    Since the option I was told to take didn't exist, I clicked "save movie" and then "high definition 1080p".  Hey I'm just trying to figure this stuff out.  I'm new to it, so I picked the highest quality I could find.
    Well, the result is a movie on YouTube that is OK, but nowhere near the quality of the movie on my computer. Just for fun, I uploaded the AVI file to YouTube from MovieMaker.  It was a huge file, it did upload, but the quality was still not there.
    So, I return to my original question, which is almost the same as the originally posted question:
    How should I save video with Premiere Elements to get the highest quality video to post to YouTube?  The videos were taken in AVCHD format, but after editing, I don't know the best rendering option to get the highest quality video when viewed on YouTube.  The videos look great on my computer, but on YouTube, the video is really degraded.
    Thanks for any help!
    I have an i7 processor, 8 gigs or RAM, and am running Windows 7 x64.  Video editing is with Premiere Elements and my video camera is a Canon HG10 that shoots AVCHD.

    I had the best success using the John Cloudman method from the link you posted.  The video was much better quality  on YouTube (in my opinion) with this method than the method of going to Movie Maker etc. I tried John Cloudman's Frame widtht of 1280 and Frame Height of 720 and then frame width 1920 frame width by 720.   I found 1920x1080 better quality on YouTube than Mr. Cloudman's 1280x720. 
    I pasted in the part of the link below that I found most useful. A big thanks to John Cloudman for posting this!!
    John Cloudman offers further advice:
    From the Share tab,  choose Personal Computer and then QuickTime.  Choose the Cable Modem,  DSL preset and then click the Advanced button.
    From the  settings window, do the following:
    b Video Tab
    *Video  Codec: H.264
    *Quality: 100
    *Frame Wdith: 1280
    *Frame Height:  720
    *Frame Rate: 29.97
    *Field Order: None
    *Pixel Aspect  Ratio: square
    *Set Bitrate: checked
    *Bitrate: 8000 kbps
    b  Audio Tab
    *Audio Code: AAC
    *Output Channels: Stereo
    *Frequency:  44kHz
    That should generate a .mov file that Youtube will  handle correctly.  You can modulate that Bitrate to reduce the amount of  data size, and  you can modulate the Quality number to reduce the  encoding time. I  wouldn't go lower than 3000 kbps for a bitrate or  below 50 on Quality.  Hope this helps everyone!

  • Windows 7x64 FF 28 renders internal "Get Add-ons" page as text only

    Setting up five new Acer Veriton E430G Windows 7 x64 desktop machines for work, each has been Windows live updated to latest spec as of end of March '14. All were brand new factory pre-installed Windows 7 x64, all have had the same set of software individually installed, Adobe Flash player, Adobe Shockwave, Acrobat Reader, QuickTime, Oracle Java 8x32 and x64, Picasa, 7-Zip, LibreOffice, Skype and of course Firefox 28.0. All have the exact same behaviour in that when the "Welcome to Firefox" first run page displays, it displays in text only with a large grey box "No video with supported format and MIME type found. If you go to Tools\Add-Ons\Get Add-ons, the internal page displays in full text only as well - no graphics, same problem when you load "Plugins" page and click "Check to see if your plugins are up to date", the following page/tab loads as text only.
    After taking one of the machines brand new out of box and creating an Acronis snapshot of the entire drive [factory install before first run] using it as a test install, I played around with a number of software / driver / updates / Firefox add-ins scenarios trying to get to the bottom of this. I have come to a dead end in as much as all runs great within Firefox, web pages from all internal pages and many on-line websites render correctly when I load a previous version of Firefox [v26.0 or v25] rather than the latest v28.0 onto each of the machines, I tried v27.01 & v27.0, these gave the same text based pages. This has been replicated successfully on the other four machines with all of the above listed latest software versions installed [no AntiVirus software installed yet as not fully in use in Office yet], change nothing else other than load the latest version v28.0 Firefox and the problem reappears.
    I did for the sake of completeness test the brand new factory install just past 'first boot set-up' and first time desktop hello, let everything settle and installed Firefox v28.0, [tested with v27.01 & v27.0] this too exhibits the exact same text only page rendering on internal Firefox pages. Yet again, over install Firefox v26.0, clear history and the same pages start loading correctly.
    I am open to suggestions regards a fix for this as I really do not want to leave the machines with old version Firefox installed on each desktop. I would also prefer not to allow each member of staff to install Google Chrome. The on-line web pages that were found to be loading as text only within Firefox 28.0 were tested and rendered correctly within Chrome 33.0.1750.154 and IE 11, this would indicate something to be clashing with Firefox or Firefox not behaving with something else. I would like to get this resolved.

    Minor update and workaround but still no fix: installing and uninstalling testing versions of Firefox again - if I stick with the bare Windows 7 Acer factory install clean out of the box [temp turn off Microsoft auto update], attach an Ethernet cable to give me internet, install Firefox 28.0 I get text only [are these pages css base?] pages for internal "Get Add-ons" page / "Welcome to Firefox" 1st run page / Mozilla "Plugin Check & Updates" page.
    If I then flush all history and close - over install 27.0.1 and repeat all of the above I get then same results. Flush all history and close again, over install 27.0 and repeat all of the above - same text based results, flush all history and close again, over install 26.0 and repeat all of the above and we have a winner. Firefox 26.0 does not have a problem displaying any of the pages correctly.
    Working my way back up version numbers again, flush all history, close Firefox, over install 27.0 and repeat all of the above and we are back to text based pages.
    I have tried a forked version of Firefox - "Pale Moon - v24.4.2" on the same machine and this gives the exact same text based results. Would this then not indicate that it is something in the base coding or settings of Firefox that has been changed after Firefox v26.0?
    Chrome and IE are displaying these Add-ons and Plugin Checks pages with no fault, why not Firefox 27 /28 ?
    In the interests of curiosity I decided to try some of the beta builds, namely 28.b9 and 29.0b7 - unfortunately same text based results :-(
    If I cannot get this to work correctly with these machines I may have to concede and let the Office users select Chrome which I really do not want to do.
    Can I run any more logs files and upload them to assist in diagnoses of this problem for a hopeful fix?

  • "Get add-ons" page on "add-ons manager" in russian instead of english.What to do?

    "Get add-ons" page on "add-ons manager" in russian instead of english. How can i change that specific page back to English.

    In case it's a weird glitch with obsolete cached files or broken cookies, you could open the Add-ons site directly and do the usual:
    https://addons.mozilla.org/
    (1) Bypass Firefox's Cache
    Use Ctrl+Shift+r to reload the page fresh from the server.
    Alternately, you also can clear Firefox's cache completely using:
    orange Firefox button (or Tools menu) > Options > Advanced
    On the Network mini-tab > Cached Web Content : "Clear Now"
    If you have a large hard drive, this might take a few minutes.
    (2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:
    * right-click and choose View Page Info > Security > "View Cookies"
    * Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"
    In the dialog that opens, you can remove the site's cookies individually.
    Then try reloading the page. Does that help?

  • I can't open add ons. mac 10.5.8.

    This issue is caused by an incompatibility of Personas Plus 1.6 with the Google Toolbar.

  • Add-Ons Manager Tab won't go away

    Using Firefox 10.0.2 on a brand-new Mac Mini running Lion 10.7.3.
    Every time I open up Firefox, it opens in two side-by-side tabs. The one on the left is my home page; the one next to it says 'Add-Ons Manager' and it simply tells me the add-ons I've installed and so on. How do I get rid of this tab? I can click the X and it goes away, but it reappears every time I open Firefox again. I can't find anything in the settings that obviously gets rid of this for good.

    Click on something below the Get Add-ons menu item on the left side of the Add-ons Manager tab.

  • Can't install add-ons on IE11

    Hi,
    I tried to install an add-on from my Chinese bank's website (Shanghai Pudong Development Bank) and after I get the black-ish screen prompting for authorization the website starts loading and then just hangs. I had the exact same problem trying to install
    an add-on from the online malware scanner eset (.eu), the pop-up with the scanner just hangs after I'm asked for authorization.
    I tried disabling my antivirus, disabling Malwarebytes, un- and reinstalling IE11 (turning it off/on) and nothing.
    In China it is not rare to see people using Windows XP, so I don't see them updating anything soon.
    I could really use some help here! Thank you all in advance.

    Hi,
    Could you please share a screenshot or guide to find and install this add-on on this site with us (I haven't used the Shanghai Pudong Development Banke), so we can know whether this is a common issue or specific issue. or you can try this add-on in another
    IE 11 (if you have) to test this issue.
    If this is not a common issue, then it might be caused by other add-ons installed in your IE 11, as a test, I suggest you disable all other add-ons, then test this issue. Tools\Manage add-ons, or launch IE by running 
    iexplore.exe -extoff
    keep Windows up-to-date, especially for IE.
    Meanwhile, you can clear the SSL state under Internet Options\Content, clear the browser history, cookies, ect, or reset IE, check if issue persists.

  • Firefox 14.0.1 Get Add-ons stuck on "Loading"

    I just purchased a new computer and, in utter spite of Internet Explorer, have downloaded trusty ol' Firefox. Unfortunately, the Get Add-ons is stuck with a bubble that says "Loading" but never actually does.
    I am using Firefox version 14.0.1, downloaded directly from the Mozilla site. I have let the thing load for almost an hour, and nothing has happened. I have tried clicking on "Extensions" or "Appearance", etc. but it hasn't helped. Every time I go back to the Get Add-ons tab it will simply say "Loading." I have also tried doing a search for a specific add-on, only to get the same thing, but in the "Search" tab.
    I have also tried rebooting the computer, rebooting Firefox, and uninstalling and reinstalling Firefox (i kept my preferences, etc. when I did this).
    Does anyone have any suggestions? I really love Firefox and I hate to think that I would have to find another browser to use because I can't download Adblocker Plus.

    Only had to remove the extensions.sqlite, and it fixed the problem perfectly. Thank you very much.
