No CSS loaded and not video does not play in FF17

I have my firefox 17.0. It didn't load the css of a Web site and may not play any video that I have the latest version of Flash 11.5. It shows only a black screen and the video is not loaded.

Hello ronak1411, I do not know if it is related to this problem, that you mentioned, but there is an extension called "DataMngr" in your list of addons that could be part of the malware on your pc. Please do a full scan of your system with software security already in place and also another tool like the free version of malwarebytes.

Fix Firefox problems caused by malicious software

then you either may want to do a firefox reset or manually remove the extension from DataMngr & install reset addon research - he'll be back customziations the most common adware programs are in default firefox: https://addons.mozilla.org/firefox/addon/searchreset/

on the issue of flash content doesn't play not - shockwave flash is not listed as one of your plugins installed, please check in firefox > addons > plugins if it's that are listed and marked as enabled. If this is not present at all, please reinstall from http://get.adobe.com/flashplayer (Please note that there are different versions of firefox and internet explore).

  • Photos and the video does not

    I have 8 GB reviews and photos and video no longer work. I have the latest firmware. I used Sansa Media Converter to load 1 picture and 1 video on the view. With the image, it will show the preview, but when I click to see the large version of the image it shows just a screen as it is a song played (title at the top, where the art of the album would be blank and the volume at the bottom of the image). This happens also with videos, but it plays the sound, just no picture. All pictures by default and video works perfectly when I bought the player, but I don't think that I never tried to load a back when I was using firmware by default. I had to update because my battery life was only a few hours.

    Too bad. I came across a thread that says turn off "TV OUT" and it works now. Sorry for not doing this before!

    I have an another question though. I am trying to load a video file large enough on the view (it's about 700 MB) and it takes forever. Y at - it something that I should do so that it doesn't take so long, or should I just wait it out?

  • L850 - 1 5 satellite replacement battery - do not load and not detected!

    Hi, I recently bought a replacement battery for my Satellite L850 - 1 5 as the stock battery was fried. The stock battery couldn't hold a full charge for more than 10 minutes.

    The replacement battery fits perfectly into the battery compartment, but the laptop does not light when the battery is in. It is not even turn on if I plug the charger ONCE I insert the new battery.

    Basically this new battery does any record with the laptop, it won't load or anything... Is it possible that it's just a battery of spleen?

    Any advice or help is massively appreciated!

    Thank you

    > It is not even turn on if I plug the charger ONCE I insert the new battery.

    In my opinion the new battery isn't fully compatible.
    Probably its a cheap Chinese product and not genuine battery out for the L850 series.

    I have no other recommendation for you than buying new, authentic and fully compatible battery.

    The battery 6 Toshiba PA5024U-1BRS (and PABAS260) must be compatible.

  • How can I force Firefox to download mp3 files and NOT play?

    Hi guys,.

    I couldn't change the settings of Firefox in this way, that it does not play mp3 files at all (in any kind of player), but allows to decide what with them for example to download the file.

    What I actually did:

    - changed at settings, that I want a dialog or download any file type and NOT use any other option (yes, all of them - not any kind of effect was seen there...)
    - changed especially all mp3-related options to download
    - deactivated ALL plugins and addons
    - about:config -> media.windows-media-foundation.enabled -> false
    - uninstalled ALL types of mediaplayers (Winamp, VLC etc.), but not WMP because it would be very complicated and would cause several bugs
    

    Many updates before (I think it's up to 20 FF or if) you could simply tell FF, I tried to download the file via the settings and now it isn't.

    Is it possible to left I can force Firefox to NOT READ mp3 files in any player and offer my the possibility to download?

    Please do NOT give answers like:

    - right click on the file and save it as ... I allready know that and do not want to use that solution. A few years before it was possible, so it should also be possible to directly click at the file and decide what to do with it. On all the sites I want to use it the possibilities are given and not blocked by the sites or implementations itself.
    

    I thank very you much for your help in advance. I'm desperately trying to find an answer to this question for months...

    Hello TurZ, please set media.windows - media - foundation.enabled back to its default value and turn media.play - stand alone false instead.

  • Any way to load/buffer a video file without playing?

    I want to read a Flash f4v file, but when I play I want to it must already be loaded and stamped before I send commands to read.

    is there an example someone a hand do that to me?

    My goal is to have some ongoing events in the SWF movie then it goes immediately to play a video, but it must be very synchronized. I don't want to play the video and that the person waiting on the video to load... I want to load the video in the background first... then when it's time for the video clip I send orders to play and everything is good to go.

    Someone of you have helpful suggestions or examples on how to do it?

    If you use FLVPlayback, assigning false to Autorun should load the video without starting to play.

  • PBS and CBS video won't play; Are ABC, FOX and NBC.

    I run Firefox version 28 on a laptop Lenovo G700 of 64-bit running Windows 8.1. I try to view the videos on news sites. Most of them (ABCNews, CNN, Fox News, NBCNews) gives me no trouble, but two of them - CBS and PBS - won't let me watch videos. (IE11 and Chrome, works of PBS, but CBS does not.) On PBS, I get an error message of "plug-in file missing '. On CBS, all I get is a black placeholder (which does not left or right click) where the video play. Sometimes, I don't get even, just white space. I updated my plugins, reinstalled Shockwave Flash several times, and I went through my plug-ins, turn them on and turn off, testing as recommended; I could not find a plugin that's causing trouble. All I know is that PBS uses a program of "JW" to put its videos. I sent CBS tech support to see if they could give me some pointers; all they do is recommend Chrome, which does not work (as I mentioned above). I'm at the end of my mind; Anyone run into this sort of thing? Note: there is probably a different solution for each Web site, because the events are different.

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

  • HP 15 laptop: DVD does not play smoothly. Help

    I got a new laptop about a month ago. At first, I was able to watch a DVD titled "Australia" and it worked perfectly fine. Now, I have tried (unsuccessfully) to watch the other two films using the preinstalled CyberLink Power Media Player 12 (the same thing that I've used before) and it does not work. What happens is I put in a DVD in my laptop and at first when he travels the sponsors or creators such as BBC, it works fine. But then comes the time for the actual film to begin with, the first audio will play while the video itself is trying to go, and then sound stops and will wait for a good ten minutes in the wait for the video to catch up with the sound. In other words, a person walking at a normal speed from point A to point B in a normal period of 3 min now takes at least 7 min for audio (which runs faster) and the video to actually play. I tested to see if it was the drive in place, but I have songs on CD on my laptop, no problem. So I don't know what to do. Any suggestions? I am also still under warranty.

    If there is a problem with the DVD material he would play no video at all so we can exclude. I'll tell you that it is a software problem so you only problems for real part of copyright subject to digital rights management. If you're ready to experiment a little, I might suggest that you try to download the VLC media player free, that will play DVDs and see if it's better.

  • First Pro CS 6 and Windows 10 - projects do not play in the timeline

    I bit the bullet and upgraded to Windows 7 Professional, Windows 10.  I had heard people say that first Pro CS 6 worked in Windows 10, so I was anxious to make the upgrade, but I was sure that it works ok.

    Boy, I was wrong!

    I can open previously created first Pro CS6 projects, and everything looks good on the timeline.  But the project will not play!  The "play" button on the changes in preview to the "Stop" button, but the current-time indicator does not move forward and the video does not play.  I can rub very well through the timeline.  If I press the "Stop" button, it won't come back on the 'Play' button, as it should.

    I tried to create a new project, import a video file and try to play it, but the same thing happens... it won't play.

    Any ideas?

    Thanks for your quick response. I solved the problem, just before that I received

    your post above...

    I realized that I had no sound at all... no windows sounds, nothing. My Realtek

    High Definition Audio sound card on my motherboard did not work. He has been

    selected as default in Windows playback device, but not sounds were

    to come. I selected another audio device and then switched back to

    the Realtek device and I had sound. Just for fun, I opened a project

    First, and he's now come back normally.

    Now, if only I could get all the 5.1 speakers, it would be

    large. It seems that I currently have audio '3.1' now! Realtek web page is

    not very useful to provide drivers. The configuration program for the

    sound card think it has side speakers, but they make no noise!

    Thanks again.
