  • what a great extension. I love firefox and i do not want to switch to chrome. google tries their best to steal firefox users.
  • Works well with Palemoon!!!
  • Excelent! :3
  • Trying to make videos on here can someone tell me how to put videos on here
  • Great addon! Only way to get Flash as default on Youtube.

    But what's with the December 31, 1969 date (as the last updated time) after it just updated?
  • Can you (please =) change Youtube Gaming to Flash too?
    Hello Rodrigo,

    We have supported YouTube Gaming for the new version. Enjoy.

    Let us know if you need any other help please.

  • it works!! : )
  • The add-on is working well. Thank you!

    It has solved some video playback issues...html5 player vs Flash Player issues at YouTube.

    I appreciate its simplicity...as well as its html5 player / Flash Player choice button.

    Again, thanks, both to Barin and Mozilla.
  • O rezil HTML5'ten kurtuluşun en kısa yolu.
    Eliniz dert görmesin kardeşim.
  • Icoontje er bij met keuze mogelijkheden. Simple en doeltreffened
  • every time i update firefox i know something will not work right. it's like waiting for the other shoe to drop. in this case after the upgrade youtube vids would no longer play full screen. i knew it was an html5 problem, but knowing that didn't fix it. this does!!!!
  • Hace lo que dice que hace. Y hay razones para preferir el reproductor flash al video en html5.
  • Good. I can see videos in HD mode without slowing speed.
  • The add-on works well in latest Firefox browser. Furthermore I can use other YouTube add-ons (for example: YouTube High Definition) which the html5 player broke.

    The option to select flash or html5 player in YouTube settings was removed by Google. This option should be added in Firefox settings IMHO.
  • You are the man for making this. Top kudos to you friend.

    I had to use this because Google forces HTML5 on Youtube now, and low and behold, forced standardization has issues, I wasn't able to view video at anything other then 360p, thanks to this add-on, I can view everything again.
    I would like to point out to other reviewers that its not Firefox thats forcing HTML5, its Google.

    Firefox is FOSS meaning, while its developer friendly, it lets you use what YOU want to use (be it flash, HTML5, Silver light, etc) I recently switched from Chrome to Firefox, and I have to say, I like it much more considering Chrome and Google were making HTML standard on everything, and were disabling silverlight (which is a plug-in many thing rely on). So up Google, and thank you based Mozilla.
  • Simple & works. Also, people got it the other way around. It is youtube who is checking which browser version you are using to access its site & then forcing html5 as default when ever possible. You can trick youtube by spoofing which version of firefox you use (ver. 36 & earlier will still get flash by default) by using a user agent spoofer too.
  • This is a life saver. Due to firefox forcing everyone to use HTML recently any videos I watched on youtube would stutter. It was a pain in the butt. Thank goodness for this.
  • Just like a few reviewers before me, I installed this add-on out of necessity to make YouTube work again. Luckily, it does the trick!
  • Buttsaver. Firefox 37.0.2 broke YouTube by insisting on Html5 video player. This addon does exactly what it says, as well as install a button on the toolbar to give you total control over your video player. Works a treat, and I'm delighted with it.
  • Just works™ — for some reason, HTML5 video in YouTube does absolutely nothing (this is Windows 8.1 Pro) and this add-on makes YouTube work again without having to resort to MSIE.

    Interestingly, it comes as a toolbar button, so you can temporarily revert to HTML5 every so often to see if Mozilla have got their act together yet :-P
  • Works good !

    Thanks.
  • Savior !
    5.1 Sound is working via flash , not via HTML. This fixes it by forcing flash back into youtube ! Excellent !
  • Just updated Firefox to 37.0.1 and 'YouTube Flash Video Player' 36.1 running fine here (no error message mentioned by another user).
  • works great, thanks!
  • Does what it says on the tin. You are a saint.
