Hello,

How do I disable the "Run Flash" icon in firefox? I'm not looking for a button to click on in the settings, I'd appreciate if there was a about:config flag I can set to allow always running flash content wherever.

I don't care about flash's vunerabilities, I'm only using firefox to run flash/.swf files from my local system's HDD (Literally no internet browsing) since chrome insists on downloading those instead of playing them.

I can't play flash videos anymore. It will try to load video, but black screen. Even if I try to right click and settings nothing happens. Add-ons page says it is installed.

Also I downloaded uninstaller and reinstalled, but no help.

Not sure if my Windows 10 insider preview is problem? Build 14267

Video playback is not working on firefox from firefox 42 to 43.09b3 ubuntu 15.10. Updated gstreamer 0.10 and 1.0 all packages and videos on facebook and older videos on youtube still not playing. Installed VLC plugin and yet no video. Used to play on ubuntu 15.04 without flash. Any help?

I disliked Edge, so I got Firefox 40 for Windows 10 .... but now I can't see Twitch TV game broadcasts / videos. If I go back to Edge, then I can see Twitch broadcasts .... so I'm thinking I'm missing a PLUG-IN for Firefox that Edge has ?? Which one is it ?? Which plug-in do I need, and how do I fix Firefox.

I'm on Firefox 46.0.1. When I am reading an article (say on SFGate.com) that has a video powered by JWPlayer, I get an error message saying "Error loading plug-in: Plug-in file not found http://ssl.p.jwpcdn.com/player/v/7.3.4/vast.swf." If I go to the same site/same video using Chrome, it works fine. Help.

I have: Firefox 38.0.5 Shockwave Flash 18.0.0.160

Problem is that when I watch a video that is NOT in youtube, there seems to be no sound. This happens on sites such as: twitch.com kissanime.com (In this site the have the option to play videos in HTML5, which works fine) and website with flash games like: kongregate.com

I used to be able to watch the National Zoo panda cam for years - https://nationalzoo.si.edu/webcams/panda-cam. About April it stopped working. It worked for 2 days earlier this week (8/23-24/17) until I installed the latest Firefox update. Why can't I see the cams any longer on this website. I get this error on many websites; videos won't load or won't play. This same error also stops videos on the CNN.com website, which is actually appreciated. I did try turning off the IPv6 - that did nothing for me with this problem.

I am running Windows 7, my computer is within 4 years old, no problems seeing the other panda cam pages from the San Diego Zoo or Zoo Atlanta.

It seems this site is unable to upload my screenshot of the page and error message. Bummer!

THANK YOU for all your help!

Flash NPAPI 22.0.0.209

I have deleted my entire profile, uninstalled and reinstall both Firefox and Flash. In windows 10, if i go to Flash Player Settings Manager, it says that i have the above version installed. However, Firefox Add-on Manager does not show Flash as a plugin (it's not in the list).

Please see system details for more information!

Any help would be appreciated! Thanks =D

Just upgraded to Firefox 40, it doesn't allow me to view any Flash Shockwave based sites or plugins, anywhere on the net.

I've installed Shockwave player. All other browser work fine.

41 seems to be working fine. 39 works fine as well.

Recently pages using Adobe Flash don't load. I get a message saying "this page requires Adobe Flash" and another asking "Do you want to activate Adobe Flash" Each time I have to choose Activate but it doesn't ask if I want to enable it always, it just does it the once and next time I load the page I have to do it again. Another issue that seems to be related is that I get a message saying "You must download Adobe Flash or enable it in your browser" on some pages that I have viewed before. One I tried tonight is : http://www.bbc.com/earth/story/20141103-hermit-crab but got the "You must download Adobe Flash or enable it in your browser" message. What's up? I read in the mozilla support chat that I must enable Flash but no clue where or how to do it. Thanks in advance.

I hate the new built in flash blocker, too much trouble to allow and disallow for certain sites and NO way to just allow for parts of a site.

Is there a way to disable it entirely? And, hopefully, allow the good old flashblock add-on that worked FLAWLESSLY to work again?

I don't understand why developers make changes that violate the old saying "If it ain't broke, don't fix it.".

I normally have Adobe Flash in "ask to activate" status. When I want to see if I have the latest ve3rsion, I go to Add-ons Manager and change the setting to "Always activate". Then I go to https://helpx.adobe.com/flash-player.html to check if I have the latest version. Then I go back and reset to ":Ask to activate".

Recently, when I go to that Adobe page and click "Check", I get an error message "Sorry, Flash Player is either not installed or not enabled.." How do I get Flash enabled? I had this happen with Flash 26.0.0.151, and I recently upgraded to 27.0.0.130, and after the update the same error message appears. I am running Firefox 55.0.3 32-bit on Windows 7 Professional.

In the past, when I had "Ask to activate", the Adobe help/check page did not ask me to activate; I had to re-set the activate flag to get the help/check page to work. Is there something that FF has saved somewhere that tells FF never to activate Flash on the Adobe help/check web page?

Thanks.

I was suddenly getting prompts to update Flash Player. This hadn't happened in months, so I hadn't updated Flash Player in a good while. The first time, I ignored the warning prompt and activated Flash anyway and played the video. This was from tcm.com (Turner Classic Movies). The second time, I decided I'd better update Flash Player, and did so. But now the video wouldn't play at all. There was a locked box icon. I searched on various fixes, looked at a few Mozilla support pages, did a plug-in change starting from the sandwich icon at upper right, same thing. Found another fix idea. Went into the C drive, navigated eventually in Windows to the Macromed and Flash folders, and deleted NPSWF32_9_0_0_169.dll. The red locked box went away. A video played. Next time out, though, back to nothing. In IE, the link will play.

When I go to http://trailers.apple.com/trailers and choose a trailer, the page will not show any movies (quicktime). I have quicktime installed (but the x64 version of Firefox says it doesnt need any other plug-in). This works when I open the page in Internet Explorer.

Btw: I run a Windows 10 system...

I updated my video drivers, have the lastest flash plugin , disabled hardware acceleration in firefox , cant disable in flash because it crashes and you cant get to the setting menu. Started firefox 44 in safe mode , same result. both html 5 and non html 5 videos work fine in explorer ( flash tests fine). html 5 works fine in firefox but NOT non-html 5 videos. Everything was fine with firefox 43.0.4 so I may have to back up to that version. Please let me know if there is anything else I can do
