Flash player is playing audio but no video (black screen)

I have a tablet running Android 4.04. I installed the latest flash player 11.3 from the google play store. It works fine when playing videos from the http://nieuws.vtm.be site with in the default (google) browser delivered with Android. When playing these flash-videos within the firefox beta version, only the audio works. The screen remains black.
I tried several videos and had always the same result.

In the Android Firefox Beta App I don't see any button from which I can get into the options tab. I only find a settings tab at the top right side, but this one does not show any options for enabling/disabling graphics acceleration. As extra information, the tablet I`m working on, is based on an Allwinner A10 (ARM8 1.2 Ghz + 400 Mhz Mali GPU) microprocessor.

I know I did not access a website any time recently, but it shows up in my drop down box in the address line, why?

The drop down box on my address bar shows a website I know I have not gone to recently. Most recent access on this website was probably about 1 year ago. My settings for clearing browser history are set for 20 days, though! (I think, I'm not very literate at this stuff) Why did this happen? It is very important for me to have an explanation for how this could have happened.

Maybe a addon? Have you tried safe mode to see if its a addon, test if those suggestions come in safe mode, see the article below.

Most of my library consists of h.264 videos wrapped in the m4v format, which my converters (Handbrake & mkvtools) says is the Apple TV format. Today I tried coverting a few to mp4 (for iPad) instead, so that I can watch them on multiple devices, but I'm running into the same problem with those that you are.
I tried resetting my ATV as the other responder suggested, but that hasn't helped. I'm still unable to watch h.264 mp4 files, while h.264 m4v's are fine.

When I open the "Save Page As" window, the drop-down box for the file name shows files that were saved long ago. This is not cleared by any "clear history" function that I can find. How do I clear this?

Hello.
I believe this is a Windows related issue, since it's the windows Save File manager we're talking about here (right?). You should contact Microsoft for help on that one, I believe. You'd expect to be able to delete the entries by simply tapping ''Delete'' on your keyboard when they are focused (that's how it goes for deleting specific form autocomplete entries in Firefox), but I haven't tried that.
I'm sorry I can't be of more help.

When I'm on Facebook and play Fish World, sending gifts is no longer working, the drop down box won't open enough to see the "send" button. It works in other games, but not in Fish World, and I contacted Fish World who said it was a browser problem.

starting yesterday I cannot get the drop down box to open to send gifts to my friends. Fish world told me a few weeks ago it was due to some updates with Facebook, but now that has been fixed and I can't get the game inFB to work. It works with other browsers - Chrome and IE9. Is there something I need to do on my end to fix this? Other facebook games work fine with drop down boxes, it's only fish world.

problem solved

HT5621 I have changed my AppleID but I can't get the "system preferrences" to show my new AppleID. What am I doing wrong?

I have changed my AppleID but I can't get the "system preferrences" to show my new AppleID. What am I doing wrong? I am running 10.9.2. I support multiple devices on this icloud account and they all work fine. Its just the mac mini ...

I found a post with the answer. Basically I just logged out of the iCloud. My concern was that I would loose my contacts. But when i logged back in with the correct AppleID -- it was all there.
Thanks!

When I now use the cmd-tab shortcut to go to a different open application it madly scrolls through all the open applications and does not let me select one. Any ideas as to what might be wrong. It doesn't appear to be a sticking key?

Problem with the cmd-tab keyboard shortcut now cured with the latest software update, so the original problem must have been a software glitch.

My 27 inch imac has just started acting weird, the thumbnail images and folder on the desktop have disappeared although the titles are still visible. When I open a programme the programme windows are all black and the drop down menus just show random

When I tried to open the web browser the browser flashed black and white at start up, then all the applications when i open a new window are completely black, I am unable to view the drop down menus as the come out as random pixels. This happens to all new applications i have been able to open. The document window opens as plain white but if you click on it it opens a document even though you cant see any thumb nails. Some of the documents are open as normal images/files. Having been a mac user for 10 years i have never seen anything like this before, any ideas or suggestions

I have started running a virus check.
There are no viruses for OSX. Uninstall the software, repair permissions and restart your computer. Especially if it's Norton's. It's known to cause problems.
To rule out a hardware problem, run the hardware test: http://support.apple.com/kb/PH11342 OS X Mountain Lion: Use Apple Hardware Test and zapp the PRAM: http://support.apple.com/kb/PH11342 OS X Mountain Lion: Use Apple Hardware Test.
In the end you may need to lug your iMac down to your local AASP or an AS. Diagnostic testing is FREE!

You got me beat by 3 yrs.

Adobe Flash player jiggles the screen on drop down boxes, videos, and animation

Any time I visit a site with drop down boxes, videos, or animation that require Flash, that portion of the screen will do a fast jiggle up and down - like it is refreshing too fast. Adobe Flash works fine in IE. Some sites the jiggle is slower than others. This is only happening with Firefox. I have searched the net for possible solutions and cannot find others with this problem. The jiggling is almost like portions of the screen have gone spastic.
I am running Windows 7 64 bit on a Toshiba Laptop . I am running Firefox 9 and Flash 11.1.102.55 64 bit plug in. I have uninstalled and reinstalled both programs and have not been able to fix it. My video driver is up to date.

Tylerdowner, as a moderator, one would think that, prior to adjusting comments/solutions, especially when not having a Mac, you would do more research (bet you know someone with a Mac, to duplicate problem), or pass responding on to a moderator who does have a Mac (I am amazed that you are even a moderator on Mac problems/situations, if you only have access to a PC). Had the solutions above worked, I would not have needed to figure out another solution (we all know the newest release of anything is the most secure). Finally I am open to any fixes (tested) that you can provide, that improve upon mine. As a moderator, maybe you have pull with the Foxtab and/or Adobe people to get them to work out compatibility, and lastly, maybe add a warning at the Foxtab add-ons page, after verifying the problem yourself, with an associate's/friend's Mac.

My laptop has a new image on it and itunes will not let me sync my iPad say I have to deauthorize one of my 5 authorizations. This laptop is one of the 5 but it no longer recognizes the iPad. How do I deauthorize?

How do I deauthorize the laptop when the original image and itunes is gone?

If you've reached five authorizations for your iTunes Store account, there will be a button in your Store account information that will allow you to deauthorize all systems associated with that account. Log into your Store account and you should see it. You can then reauthorize the computers you're using now.

Has Photoshop CS5 Extended added a "Behind" and "Clear" in MODE drop down box?

Hi Guys,
I am not sure what just happened with my PS. Was downloading and installing some custom patterns and brushes from the net last night. And when I went to try them out I noticed the drop down box had 2 new added effects ( Behind and Clear ) which I was not able to even access because they were not live. It is the drop down box which has the normal, dissolve, darken, multiply etc. etc. up on the top left hand bar. I was going to upload a picture but I keep getting a message saying this file is forbidden, even after I scaled the image down to the required fields. I was wondering if some one can help. I hope it wasn't a virus from the internet files I downloaded.
Many thanks, Grace.

They are brush blend modes. To use you need to have the brush tool selected. Open a new layer and paint with any colour. Chose another colour and make the blend mode Behind. I bet you know what will happen now? ;-)
Clear works pretty much the same as the Eraser tool as far as I can tell. Might need to actually read the manual to get more info on that.
