Prevent firefox from using HTML5 player in Youtube.

How do I prevent firefox from using HTML5 player in youtube and use flash player instead? I am not sure what advantage HTML5 has over Flash. I noticed that Flash plays smoother than HTML5 and there is also a difference in quality of the video at low resolution. HTML5 does not seem to have smooth streaming compared to Flash. I may be wrong and I am ready to learn the advantage of HTML5 over Flash. But until then I wish to revert FF to its previous behavior of playing in flash.
If there is no way of bypassing this player (html5), how do I set it to ask before I allow it to play the video? I dislike videos playing automatically as soon as I open the link or any websites (reason why I set Flash player to 'ask to activate').
Thank you for your generous help. :)

I found info here
* http://www.ghacks.net/2014/07/17/google-enforces-html5-youtube-firefox-33-newer/ <blockquote><snip> .... What this means is that Google will enforce the use of HTML5 video on YouTube for all Firefox users who use Firefox 33 or newer on their system to do so (Note this means Firefox Nightly currently, but on Tuesday also Firefox Aurora).
Update: Google seems to have delayed the change. Firefox 34 users can switch players right now on the site. .... <snip></blockquote>
In fact must choose earlier than 33 so I used

  • Ho to prevent firefox from blocking Flash player

    Dear All,
    I cannot get Firefox 5.0 to use Adobe Flash Player. When I run http://www.mozilla.com/en-US/plugincheck/ I always see the message "For your safety, Firefox has disabled your outdated version of Flash. Please upgrade to the latest version." The thing is, I have the latest version of Flash plugin (10.3.181.34) installed. I have tried uninstalling the Flash plugin (including using the uninstaller form Adobe's website) and installing it again (there are no errors reported during installation) without effect.
    Here is some more background in case it's relevant:
    +Installed Firefox 5.0 after clean install of Windows 7 Ultimate 64-bit. The computer is on a Windows domain.
    +I manually copied some files (bookmarks, etc.) to the newly created profile
    +When prompted to install Flash player I did so. The installation had no effect in that Firefox keeps asking me to install the plugin.
    +Other plugins work fine (I have a limited set of standard plugins).
    +I have tried reinstalling Firefox (even an older version 3.6.18) and the problem persists.
    +I manually added the entry "dom.ipc.plugins.enabled.npswf32.dll" in about:config, with no effect
    +There is no mention of Flash in about:plugins
    I have exhausted the solutions I have seen suggested in various places on the web. I would greatly appreciate if somebody could help me sort this issue out - I love Firefox but it's impossible to switch to different browser every time I need to view Flash content.
    Best,
    S.

    Thanks for your interest, guys.
    Maybe we are getting somewhere.
    In HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins
    I do not have the reference to FlashPlayer.
    Is that surprising given the following registry entry for FlashPlayer:

  • How do I prevent Firefox from using random, incorrect icons? (Win8.1)

    I have this strange problem where Firefox (v30.0) is using random, incorrect icons both in the GUI and on certain web pages (especially Gmail). When I use the mouse to hover over the icon it then switches to the correct icon. I've tried restarting Firefox, reinstalling Firefox, reinstalling Firefox with reboot, nothing helps. I can't find anything on this in user forums. These seems to have just occurred in the past 2 weeks, not sure if there was a Firefox update involved.
    Thank you for the help!

    You can try to disable hardware acceleration in Firefox.
    *Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
    You need close and restart Firefox after toggling this setting.

    How can I prevent Firefox from cleaning my clipboard at exit (exit or closing firefox) ?
    I am using FF 9.0.1 and the problem start from FF 5.0

    You can't prevent that.<br />
    If you've placed data on the clipboard in Firefox then you need to paste that data in the other program, if that is your intention, before closing Firefox.

  • How can I prevent Firefox from re-installing test pilot?

    I had removed the test pilot extension and its feedback button in Firefox 4.0b9. I let Firefox upgrade itself to 4.0b10 and didn't notice that silently re-installed it.
    I was typing in another application when suddenly that window was minimized and the focus shifted to a Firefox "new test pilot study" window that popped up. Even if I had given permission for that software to be installed, that is rude.
    I am not willing to trust that if I disable this logging software that it will stay disabled the next time I upgrade. I will remove test pilot again. '''How can I prevent Firefox from re-installing it?'''
    One way might be to set extensions.rdf read-only. However, I do not wish to lose the ability to install add-ons, I merely do not want anybody (including Mozilla) to install an add-on without my permission.
    https://bugzilla.mozilla.org/show_bug.cgi?id=519357 doesn't seem to address this problem as test pilot is a known component. Its not a plug-in so I can't modify the plugin scanning settings to prevent it from being loaded. Is there some way I can reliably supplement http://www.mozilla.com/en-US/blocklist/ with a local block list file? If so, would I have to update that whenever a new version of test Pilot is released?

    I'm not sure what you mean by "re-directs e-mails." Are the recipient addresses changing between the time you address the message and the time it is sent?
    If you could provide more information I think that would help in tracking this down.
    When you use Firefox to work with your webmail site, whether Yahoo! or Gmail or another, the mechanics of sending the mail are handled by the site itself. So if there is a problem with how messages are addressed, then you may need to check your Yahoo! mail settings.

  • How to prevent Firefox from playing any kind of video in the browser instead of promting a download dialog

    When i klick on a link for a video files (for example a .wmv File) it opens a new tab and starts playing it, instead of giving me a dialog what it should do with the File so that i can either download it or play it with an external player. I already set all the video files in the "options -> Applications" screen to "Always ask", but instead of asking me, it's simply playing them.
    What can i do to prevent firefox from playing videos?

    Tahnks, but that doesn't help me at all. As i said, i already changed all to "Always Ask", when i Filter for media i get 5 results where each says "Always Ask", so thats not the cause...
    I realized yesterday that this does not happen with all formats, it happens with wmv but not with avi... but still dont know y -.-

  • Possible to prevent Firefox from loading two versions of Flash, without disabling PLID scan?

    Our IT department—what a great way to start a question—does not roll out regular updates for Flash. To bridge this security gap for Firefox on my work computer, I copy the following files:
    * flashplayer.xpt
    * FlashPlayerPlugin_<version>.exe
    * FlashUtil32_<version>_Plugin.exe
    * NPSWF32_<version>.dll
    from C:\Windows\System32\Macromed\Flash on another machine and paste them to
    C:\Users\<myusername>\AppData\Roaming\Mozilla\Plugins on my work machine. When Firefox starts, it scans the various locations (http://kb.mozillazine.org/Plugin_scanning) and finds both this version and of course the outdated version originally installed, which IT does not update (currently 11.1.102.55). This effectively updates Flash, and until IT finds a solution to distribute updates I'll have to continue to update Flash manually (Java is unfortunately not so easy to fix), but still leaves me with a problem.
    My perceived problem is that Firefox still scans the default installation directory of Flash and thus finds the outdated version. Under Add-ons > Plug-ins, I can select from "Ask to Activate," "Always Activate" and "Never Activate." If I select "Ask to Activate" for the current version (12.0.0.43) and "Never Activate" for the old version (11.1.102.55), upon restarting Firefox it sets both to "Ask to Activate." I conclude that Firefox does not treat separate Flash versions independently. Since constantly being prompted to activate Flash is bothersome, I could just set both to "Always Activate," but that leaves an old, even-more-compromised-than-the-current version of Flash activated.
    The best solution, I suppose, would be to uninstall the outdated version of Flash, but I don't have the administrative rights to do so, and don't want to pester our IT administrators. I could prevent Firefox from scanning the directories specified in the Windows registry for PLIDs (see above link), but this would prevent it from finding my also-outdated-but-only-installed Java Plug-In, which I keep thinking I need. The behavior I'm after is to prevent Firefox from scanning or finding the old Flash version, while still finding my Java Plug-in. How could I go about this?
    Thanks

    Maybe you can check the pluginreg.dat file to see if you can disable/remove the other Flash plugin and make the file read-only to prevent changes.
    You can use this button to go to the Firefox profile folder:

  • How do prevent firefox from loading(going to) a website(following a link, etc...) that i never want to see again(example: choose now & click on some link in the future)?

    I go to a website(link, etc...) & I never want to go there again, but sometime(anytime) later I come across some page that seems to be useful. I click on a link, and the other required links until I find that it is a waste of time & I then kind of remember having been there in the past & have wasted all this time again. This happening for many different sites over time.

  • How can I prevent firefox from displaying an overall black page after I request a topic search in the google/firefox search box? Not able to see results

    I loaded Mozilla v31 on my PC laptop which uses Windows XP operating system with all current updates. When I click on my internet icon, it leads me to the Mozilla page with a Google search bar. Once I type a topic in and click for the search to begin, the Firefox page turns all black and I am not able to see any results or action being taken. I click on the back arrow and enter a new topic, and click on search button, it repeats the same behavior and the Firefox page turns black. Essentially Mozilla Firefox is not a usable browser unless I can fix it. Help!

    When this happens, has the address bar changed to a google.com address or is it still blank?
    Some graphical glitches are caused by an incompatibility between Firefox and your graphics card drivers. The standard workaround for bypassing this is to disable Firefox from using hardware acceleration. You can make that change here:
    "3-bar" menu button (or Tools menu) > Options > Advanced
    On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"
    That will take effect the next time you exit Firefox and start it up again.
    More generally:
    When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
    (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:
    "3-bar" menu 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"
    * (menu bar) Tools > 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?

  • Digital Signatures - how to prevent anyone from using my name

    I've created a bunch of forms that have digital signatures enabled.  When I've created one either with the PKCS or the Windows Certificate, what's to prevent anyone else from just typing my name, email address and Company Name?  Yes, I can create one and save it with a password, but anyone can do that.  I'm confused how I can ask our users to use digital signatures on internal documents, then have them email to accounting or HR, yet there's nothing to prevent anyone from using anyone else's name (ie how can I prove that it wasn't me that signed it)? 
    Is there nothing that's tied to Windows ie I can't use my login ID on our domain unless I use my network password?  That's really the ONLY way I can prove I'm me. 

    Self-signed digital signatures are precisely that - the person creating them is the only one attesting to the contents, so you can make a perfectly-valid self-signed ID for Canta Claus of you want to. The critical thing to remember is that a self-signed ID will only validate if the recipient has your keyfile to compare it to. On your own machine it will show as valid because the key is present, but if you send the PDF to anyone else it will show as invalid unless you have separately transferred them a copy of your keyfile. It's that second file which tells them the ID is really yours, as they can physically check where it came from (e.g. by phoning you up). The recipient would then have to manually add the keyfile to the trusted list in Acrobat or Adobe Reader, and finally your PDF signature will get the green tick.
    Self-signed IDs are find for internal company workflows as everyone can share their keyfiles, and the IT department can manage what's going on. If you're using digital IDs in a public setting you should never use self-signed certificates, instead you should purchase an ID from a Certificate Authority - a company whose IDs are tied to the 'root certificates' embedded in Acrobat and Adobe Reader. The CA will require proof of identity before selling you the cert, and so anyone can verify it's genuine without needing to contact you. CAS-issued certs for signing PDF files are not cheap, there are several vendors out there and I won't comment on which may be better.

  • How to prevent Oracle from using an index when joining two tables ...

    How to prevent Oracle from using an index when joining two tables to get an inline view which is used in an update statement?
    O.K. I think I have to explain what I mean:
    When joining two tables which have many entries sometimes it es better not to use an index on the column used as join criteria.
    I have two tables: table A and table B.
    Table A has 4.000.000 entries and table B has 700.000 entries.
    I have a join of both tables with a numeric column as join criteria.
    There is an index on this column in table A.
    So I instead of
      where (A.col = B.col)I want to use
      where (A.col+0 = B.col)in order to prevent Oracle from using the index.
    When I use the join in a select statement it works.
    But when I use the join as inline view in an update statement I get the error ORA-01779.
    When I remove the "+0" the update statement works. (The column col is unique in table B).
    Any ideas why this happens?
    Thank you very much in advance for any help.
    Regards Hartmut

    I think you should post an properly formatted explain plan output using DBMS_XPLAN.DISPLAY including the "Predicate Information" section below the plan to provide more details regarding your query resp. update statement. Please use the \[code\] and \[code\] tags to enhance readability of the output provided:
    In SQL*Plus:
    SET LINESIZE 130
    EXPLAIN PLAN FOR <your statement>;
    SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);Usually if you're using the CBO (cost based optimizer) and have reasonable statistics gathered on the database objects used the optimizer should be able to determine if it is better to use the existing index or not.
    Things look different if you don't have statistics, you have outdated/wrong statistics or deliberately still use the RBO (rule based optimizer). In this case you would have to use other means to prevent the index usage, the most obvious would be the already mentioned NO_INDEX or FULL hint.
    But I strongly recommend to check in first place why the optimizer apparently seems to choose an inappropriate index access path.
