Firefox Support Forum

I went to check my plugins and saw that I needed to update my flash player from 18 but when I went to install the new version and checked to make sure it installed correctly by checking my plugins again it said I needed to update. I went to my plugins section of firefox and noticed that it had installed the latest version but hadn't deleted the old version.

I then downloaded the flash player uninstaller and used it. I restarted my computer to make sure and noticed that it hadn't worked.

Also to note that it's just in firefox plugin. My computer has the updated version.

So anyone know how to uninstall the plugin?

I right-click on video or flash(.swf files), and firefox browser is slow down and 3~4 seconds later it works I use Window 10, 64bit. It doesn't happen in Chrome browser or IE.

I'm having video playback issues with Adobe Flash player on Firefox. The video blinks (flashes a blank screen every 2-3 frames) and displays random mpeg artifacts.

Here is the link to the video; http://www.netd.com/canli-yayin/kanal-d

Same video plays fine with IE and Chrome on the same system. I'm running Firefox 40.0.3 with Adobe Flash Player v18.0.0.232 on Windows 7 UE x64 SP1.

I can't play twitter incorporated movies. This one for example cannot be read : https://twitter.com/BeaujolaisNvx/status/664015437680607232 Safe mode doesn't change anything. I've create a full new brand "home" directory from scratch. No change. I've seen some reports about fiddling in about:config. No change either (I don't even find the entry key blabla-media-foundation-blabla).

Vines movies, on the other hand, are handled sucessfully Like this one for example: https://vine.co/v/eUXxn20mKZW

Flash is up-to-date on my Linux-gentoo box 11.2.202.548 Java is up-to-date. Video Codec OpenH264 installed by Cisco systems Firefox version is 38.4.0

Any help would be greatly appreciated ! Thanks

Running Windows XP sp2. Firefox 5.0 (latest), Adobe Flash Player 23.0.0.207 (latest). I completely removed and re-installed both Firefox and Flash Player since the problem started. I still have the problem.

On Facebook, I am no longer able to play the videos. It was working. I have had this problem before and was able to fix it by updating Flash Player, but that did not work this time. It appears that plugin-container is trying to start, but failing. There is not error message.

Can anyone help? Sincerely, Fred

When the crash occurs - the screen gets transparent, there is a note about firefox stopping to respond and I have to close it out. My browser is 43.0.1

I noticed it may have something to do with the ads, because I opened my email to read email from support.mozilla.org and it crashed. Then the window was restored and I was able to read it.

The browser was reinstalled and refreshed. I have no add-ons and no extensions. But I have plugins. I disabled some and changed the rest to ask to activate.

I was able to download video by going to options/page info/media in version 41, but video no longer appears in the list. This is the case for pages where I was able to download video just 2 weeks ago. I have tried updating my addons, but that made no difference. I have seen that other people have noted this problem.

Example here;

With Adblock disabled (on both accuweather and its videowall site) the preliminary ad will play but none of the videos after the ads would play. They will play using IE. I've written to them however they won't help.

Hi,

On debugging any website to validate Adobe tags using DTM switch (i.e. DTM switch installed), there seem to be no tags fired at all while the same are being fired in other browsers.

Hello

I am trying to set up a discussion in Canvas. When I click on Record/Upload Media, a window pops up with Adobe Flash Player Setting asking me to click on Allow, nothing works on the window...However when I do the same on Safari and Chrome, no problem it works... I am also having mega problems on another online platform "Portails" when I also use Firefox (I suspect this is a Flash player problem...) and same thing, when I use Chrome everything works...I have uninstalled and reinstalled Firefox and downloaded the latest version of Adobe flash player..it did not help...I have a Mac Pro... thanks...

I'd like to try to switch back from Chrome to Firefox, but there is an issue that makes it impossible. When I play any video with Firefox it works very slow and quality worse than in Chrome. For example, when I expand the video to fullscreen it switches very slow and the only way to exit fullscreen mode is to press Esc. But in Chrome all works fine. I've recorded a video with a demonstration of it. Please, check this out (https://goo.gl/eTtOku). My system is Xubuntu 14.04, video Radeon HD 7640G with fglrx drivers. I do not use flash and hardware acceleration is enabled.

anytime I try and play a youtube video firefox simply quits. The problem seems to be youtube as I can play videos, for instance, from vice news. I am using ubuntu 14.04.2 and firefox v40. I have tried this several times. Usually there is nothing, 1 time, however, it said firefox had a problem and to send it off, which I did. My problem is that happened only 1 time out of maybe 5.

Thank you...............

I recently downloaded Firefox on a PC, it was my default browser and everything was running fine. I added extensions including Ghostery and Add Block Plus which work fine on my other browsers and I think on Firefox for a while. Now I can't get the video to work on popular websites (e.g. the Weather Channel) even if I disable Ghostery and Add Block Plus which I don't think are the problem anyway. So I messed up something. Any thoughts would be appreciated.

I tried so hard not to contact you guys because your answer will be, start in safe mode disable all plugins etc etc.

After every update Firefox give trouble but this time it won't let me watch video on websites. After playing a video within minutes it get choppy and slow. My OS:windows vista, drivers, graphic card, video/audio codecs everything is up to date.

Usually I do not type hard words but sorry for that, if anyone got any solution please let me know.

Thank you

I currently use version 46.0.1and somethings are different in a good way but unless I am completely stupid and fail to see what use to be right under my nose, a survey site that uses the 'jwplayer' (? thats the logo it shows) and video in the format of mp4's dont, wont and cant play in firefox like they use to. I investigated and found I have no plugins to play video content. There is listed : ÖpenH264 ? and Primetime decryption modules, Adobe Acrobat and Shockwave. Thats it - thats all there is. Did I miss something or have you included the java inside firefox itself so we dont have to worry about updating it constantly? Could omeone tell me which rock I need to look under for it , or what is happening to it.

I have completely recovered my laptop several times since January and havent been paying much attention to whats up in the newsletters. So it is feasible I walked right past something important , I just dont know. HELP ME PRETTY PLEASE, BEFORE I GO COMPLETELY BATTY..........sigh  :(

Thanks

Hi,

When I try to login to adobe.com.au, I get a dialog box asking me what to do with a login.do file. I do not have this problem on any other website I login to, and I can login to the site using IE or Chrome. It worked some weeks back but I am not sure what version of FF that was or what Windows 7 level it was before any Win7 updates. Adobe tells me it is a FF problem but I am not so sure.

TIA

Steve
