Firefox and Youtube videos

Initially after installing Leopard Youtube videos would play fine in Firefox, now the Player window does not open in Firefox. Any ideas

No. YouTube does not use QuickTime. YouTube videos are VP3 encoded Flash videos. You need Flash Player. The current version of Adobe Flash Player (Version: 9,0,47,0) can be downloaded here: http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash&promoid=BIOW
Moreover, the current version of Flip4Mac WMV is not fully compatible with OS X 10.5. You must use the v2.2.0.39 beta, which you can download here: http://www.flip4mac.com/wmvbetaregister.htm

How can I get webpages and YouTube videos to load faster?

Webpages and YouTube videos load painfully slow and sometimes not at all on my iPad. I rarely have more than one signal bar lit. It hasn't always been this way. Nothing has changed with my wireless service. I tried clearing my history but that didn't help. Any ideas? Thanks!

Close other apps that are running. Double click the home button, and (assuming you're running iOS 7) swipe up toward the top of the screen the images that appear over the app icons you see to close those apps.
Also close extra Safari tabs you may have open.

After upgrading to Firefox 24, YouTube videos never load

I have Lubuntu 12.04 and Gnash. Up until yesterday (when Upgrade Manager uploaded the latest Firefox to version 24) all was well.
NOW, the page loads, I click on the large "Play" symbol superimposed over the video image, and all I get thereafter is the circling dots loading symbol.
Gnash gets far enough that it creates the "videoplayback__" file for the video, but it is typically only a few kb large (and it cannot be played, naturally).
If there is a workaround/solution, great - if not, please tell me how to get version 23 back (but also let me know when the problem is fixed so I can get the new fixed version)
Thank you.
P.S. To get this question down to an acceptable size, I deleted all the printer-related Troubleshooting Information that for some reason Troubleshooter saw fit to include....
Before I did so, I was told to: "Ensure this value has at most 30,000 characters (it has 47,676)." ("Value" ???)

YouTube videos freezing up after about 30s
I am contributing the following observations both as information and in an effort to help FF find a fix for what broadly speaking is an on-going problem, but possibly not as some users have suggested specifically with FF or on the other hand with Adobe Flash. Please forgive the length.
After updating FF23.0.1 to FF24.0 and updating Adobe Flash Player from 11.8.* to 11.9.900.117 shortly afterwards I have found that when using my broadband dongle ANY YouTube video I play in FF freezes up after 26-30 seconds although the progress bar continues; if I give it long enough the screen turns green - a first for me - and I receive a message that the Adobe Flash Player has crashed. The SAME effect occurs in Google Chrome using its default Adobe Flash Player, v11.8.* (it recognizes 11.9.900.117, but I have not tried that in Chrome yet).
With Opera v12.16 and v15, however, with and WITHOUT the turbo feature on for slow connections, I have no problem with YouTube videos. In a single test using FF with an ethernet connection YouTube videos played properly. So, superficially, the problem would seem to be related to a slow connection speed with the dongle, although this does not explain the crashing of the Flash Player in FF and Chrome, but not in Opera: I have been using the dongle since December 2009 and have NEVER encountered this issue before. Also, with FF, I tried playing a flash video on another website at various qualities and the video did not freeze up. So, why this problem with YouTube? It might also be added that FF users have been reporting FF/Adobe Flash/YouTube problems for at least a few years and it is unlikely that they were all using broadband dongles. I do have some difficulty playing some Quicktime videos while using my dongle, which may also suggest an internet connection issue; nevertheless, as noted, this does not explain the persistent and unusual crashing of the Flash Player or the green-screen effect or Opera's ability to play YouTube videos.

Flash Player 11.7.700.169 and Youtube videos viewing problem

I have just updated to the latest version of Flash Player 11.7.700.169 I cannot view many of my favorite YouTube as it ask me over and over again to update to the latest version . This is the latest version and I did it 4 times in arow. Always unable to watch many Youtube videos now. Anyone had encounter the same problem? I have Vista and Explorer 9. This just happen this morning. Didn't have any problem yesterday before this morning.Can someone tell me what is wrong and help me fix this annoying issue? Thank you

I'm having the same issue; non-HTML5 videos won't play. Specifically they start for a couple seconds and then freeze. I'm running Windows XP and Firefox.. I tried de-selecting hardware acceleration, increased the local storage, and I don't know what else to do. XP, Firefox, and Flash are all the latest versions.
This has only been for the last 2-3 weeks, and the only things that have changed are updated Flash, updated Firefox, and supervisor installed Norton while I was on vacation.
Please, any suggestions?
ETA: And just like that, it's working! I think that I probably should have restarted the computer after changing my settings yesterday. Or not; still confused but relieved.

I use https and youtube videos show "an error occured, try again", i try clearing the cache and cokies, i try uncheck the hardware acceleration but no result

also i try set the security.ssl.allow to true but no result.
everything right with IE but problem only with firefox :(
please help me

Hi,
Does this happen in Safe Mode or with extensions/plugins disabled? [[Troubleshoot Firefox issues using Safe Mode]]
[Try the add on HTTPS Everywhere and disable youtube.com in the HTTPS Everywhere rules and I can watch YouTube videos in this Firefox profile as long as it's not over SSL]
In youtube you can also try to change the video quality or disable hardware acceleration.
Some problems with Flash video playback can be resolved by disabling hardware acceleration in your Flash Player settings. (See [[Flash Plugin - Keep it up to date and troubleshoot problems|this article]] for more information on using the Flash plugin in Firefox).
To disable hardware acceleration in Flash Player:
#Go to this [http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues Adobe Flash Player Help page].
#Right-click on the Flash Player logo on that page.
#Click on '''Settings''' in the context menu. The Adobe Flash Player Settings screen will open.
# Click on the icon at the bottom-left of the Adobe Flash Player Settings window to open the Display panel. [[Image:fpSettings1.PNG]] 
# Remove the check mark from '''Enable hardware acceleration'''.
# Click '''Close''' to close the Adobe Flash Player Settings Window.
# Restart Firefox.
This [http://www.macromedia.com/support/documentation/en/flashplayer/help/help01.html Flash Player Help - Display Settings page] has more information on Flash Player hardware acceleration, if you're interested.
Does this solve the problem? Let us know.

Can't play music on ipod and youtube videos on speaker mode after update

Hi people!
I just updated to version 3.12 yesterday and after which, i tried playing songs with ipod mode and the speaker was not working. Tried plugging on a earphone and was able to listen to the music. The same issue was encountered on playing YouTube videos on the phone via speaker mode. The speakers however works when someone calls and while communicating via speaker mode on a phone call.
I tried to do a system restore but was unable to revert back to the previous version 3.11 on my backup file. The same issues were encounter after doing a restore and notice that the phone boots up from a hard reset significantly longer and some ringtone files which shows already sync into the phone on itunes was not found on the iphone itself.
However just when i was about to give up, i tried one last time to reboot the phone again to troubleshoot if the speakers was the one causing the problem, I tried setting "Lock sounds" and "Keyboard Clicks" off and on again and was able to get the speakers working now for ipod and youtube. Thanks goodness the speakers wasn't spoiled.
But when i sync some of my music files back from my computer again and every time i hook up to charge my phone, the problems keep coming back...
Is there anyone encountering this problem too and any permanent solutions or should i just visit the service center for a peace of mind as i do have 6 months of warranty left...
Thank you all for your time. Regards...

Try the standared fixes:
- Reset. Nothing will be lost.
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory defaults.

Facebook and Youtube Video Setting Compression and Tools?

Hi Folks,
I'd like to start putting our Live band videos up on Facebook and YouTube, and I was wondering what the latest trends are in that direction.
I have the freebies MPEG Streamclip, ffmpegX, as well as some of the the older Macintosh products Final Cut Express HD 3.0, and iMovie 6.0.3, and also the Latest QuickTime Pro 7.6.4..
I know that there is a lot of information out there as well as misinformation, (or old information) and I was just wondering what the best ways to get the best compression setting, the best sounding audio and looking video up to these sites.
Thank You For Your Time,
Eric

in case, your source is HDef, I prefer a 1280x720/30fps/h264/max. 6MBit/sec conversion.. (=you can set FC/e or iMovie in the Export with Quicktime/Options) YT cares for approbiate download (=smaller for older computers) ..
I'm not familiar with FB .. me too old for such..

Why do GarageBand, iMovie, Photobooth, and Hulu and Youtube videos slow down my whole computer?

I have a higher end 13" MacBook Pro running OSX Snow Leopard 10.6.8 that I purchased in August of 2010. About a month ago, I was using iMovie to edit a project when all of a sudden it started responding extremely slowly. Like, near impossible to work on my project slow. The whole computer was lagging, the mouse was unresponsive and I could barely use the gestures on the trackpad to get to different programs. Eventually the pinwheel of death showed up, and I quit iMovie. As soon as it closed, everything returned to normal. I restarted the computer to see if that would help, but as soon as I opened iMovie again, the whole computer started lagging. I then noticed that the same problem occured when I used GarageBand, iPhoto, Skype, and when I watched Hulu or YouTube videos. With all of these programs/sites, everything is running fine beforehand, but when I open them up, chaos sets in. This problem doesn't occur when I use other intensive programs like Photoshop or Illustrator, nor while I'm browsing the web. The only web problems are when I watch a video. Any video. Other than that, web pages are as quick to load as ever, and I can use the computer normally for any other task. This is seriously a problem because I use iMovie and GarageBand for school a lot, and my grades depend on me being able to use these programs effectively. All of these problems have persisted with these apps since that first instance about a month ago, and no significant changes occurred to instigate them. In attempts to solve the situation, I have cleared my cache, freed up space on my drive (I have 56 free gigs out of 320), I have verified and repaired the disk permissions, and I have downloaded the Apple provided Trojan removal tool for Snow Leopard. This seemed to work for about 10 minutes, but the apps and videos quickly started lagging and slowing down my whole computer again. If anyone else has experienced anything like this, I would love to hear exactly what has happened to you and to see what you did to [try to] fix it. Thanks for reading all of this, I need all the help I can get right now. Also, I can't watch The Daily Show or The Colbert Report on Hulu anymore, and it's killing me! Thanks again.

It's very difficult to say without knowing more about your system. There are a number of possibilities. First, your 13" lacks a discrete GPU, so the CPU is doing the work that a GPU would have done as far as decoding video streams, etc. Each video stream will consume considerable resources from the machine, and if you have multiple things running with video streams being decoded (for example, a browser with video Flash or cumbersome animation and iMovie running at the same time), then that may be a factor.
Additionally, it could be that you are memory constrained. You didn't post a picture of the process list from activity monitor or the memory usage stats, but you probably want to look and see what the memory and CPU usage is and who's consuming what. Some applications are pretty inefficient. For example, if you have iPhoto open and have thousands of images, the indexed metadata and thumbnails are all stored in RAM. iMovie pulls in clip thumbnail sets - (and worse, it has to do on-the-fly transcoding video assets from some cameras that don't encode the video using the parameters it expects to make indexing frames easier). Again, this would show up as periodic spikes in CPU activity for the app.
You seem to have plenty of disk space, that's not likely to be a problem.
Check if Time Machine is running. Time Machine introduces a performance impact, but it's exacerbated by the presence of frequently changed large files (e.g., you don't want Time Machine backing up your video projects while you are working on them).
Lastly, you may consider checking the console for error messages. This might reveal background processes that might be bogging down the system, or things like filesystem/disk errors. If there are errors in the filesystem, when you access certain portions of the disk, the OS and applications can slow down or lock-up as a result.

Im having trouble playing games, dvds and youtube videos. any help?

Im having trouble playing CD games on my Mac. They open and then close right away everything i need is downloaded. I have trouble watching some YouTube videos. Some play and then the others either go in slow motion or dont play at all. I also am having trouble playing DVDs. the DVD play opens then says that "a valid video device could not be found for playback". If anyone can help me out that wpuld be great.

For server issues try using OpenDNS servers. System Preferences>Network>Advanced>DNS.
Click on the + in the left column and insert the following:
208.67.222.222
208.67.220.220
Click OK, then click Apply
For you reference: http://www.opendns.com
Actually 10.8.3 is snappier than before. Even Safari (updated). Boot to your ML recovery disk and run Repair Disk from Disk Utility.

Macbook is slow to load webpages and youtube videos are stopping

I just recently purchased a Macbook pro, however, its been slow to load webpages, youtube videos, etc. The youtube videos frequently stop playing and I have to reload the page. Its not the connection and I havent had the computer long enough to have to clear safari chache. WHY

Sorry to bump this, but I'm having the same issue, though it's not a poor router problem (upgraded that hoping it would fix it).
I tried the OpenDNS and it helped once, then stopped loading Netflix (Netflix, Youtube, and Facebook seem to be common problems, as well as "new" webpages that I don't go to often). If I connect directly to my Ethernet the internet works great. My iPhone connected to WiFi works great. It's just my Macbook pro and it just recently happened when I moved to my new house (I had the same ISP at an apartment and had 0 issues). Any thoughts?

Firefox downloads Youtube videos.

Seems with the new Youtube .webm format videos, Firefox downloads the video causing less space in the hard drive, the files are in the C:/Windows/Temp Folder

Safari > Preferences > Security > Internet Plug-ins
Checkmark the box beside "Allow Plug-ins".
Best.

Facebook and youtube videos don't work on firefox. (Vimeo does & videos work on chrome and opera)

When I try to open an video in youtube or facebook the player just goes black and white.
With google chrome and opera I don't got any problems..

Hello,
Starting in Firefox 23, if a secure page includes certain types of insecure content, Firefox blocks the insecure content and a shield icon will appear in the address bar. See this article for more information about the new mixed content blocker: [[How does content that isn't secure affect my safety?]]
To temporarily allow the mixed content to be displayed:
*Click the '''shield icon''' [[Image:Mixed Content Shield]] in the address bar and choose '''Disable Protection on This Page''' from the dropdown menu.
[[Image:Fx23MixedContentBlocker]]
To allow insecure content to be displayed in all secure pages, enter '''about:config''' in the address bar and double-click on this preference, to toggle it from true to false:
'''security.mixed_content.block_active_content'''
You can also use this add-on instead, to toggle the preference:
*[https://addons.mozilla.org/firefox/addon/toggle-mixed-active-content/ Toggle Mixed active content] add-on
You may want to do this only for the current session, then reset the preference back to "true" and check back with the site to see whether it's been fixed, since this is a global setting that exposes you on all sites, not just the one you care about.
Let us know if this helps!

Why doesn't firefox open youtube videos, istead whole server get jam.

Only way to get out is stop process. When open videos sound and music is playing, but video stops after 0-2 second. Then firefox is jammed, nothing works.

Make sure that you allow the plugin-container in the firewall.

You can also try to disable the hardware acceleration in the Flash Player.
