Firefox is slow and hangs watching Youtube videos. Safari is OK. What's the word, Developers?

Since late Oct 2011, my Firefox had been hanging while watching videos on Youtube. Any mouse action while a video is playing causes Firefox to hang (spinning wheel).
It turns out that I had caught the beta release of the new Gray Youtube interface - where the backgrounds of all youtube pages are gray.
I got myself back to the old interface by deleting all Youtube cookies.
I no longer have hangs. Page transitions are also much quicker, as was before.
Is there anyone else who has experienced the "new" interface, and problems?
If you do have the new youtube interface, but no problems, then I have more digging to do.
Update Dec 2, 2011:
I have the problem again now that Youtube has released their "new look" interface to everyone.
The problem is generally slow Firefox responses to mouse actions while watching Youtube videos. Firefox will hang completely 2-4 minutes into any Youtube video. (The video does continue to play a-ok.) FF becomes responsive again when the video ends playing.
Problem doesn't occur when I watch a youtube video right after starting FF after having "quit" it. Problem begins occur after FF has been running for a while (visiting other websites?) Is this a symptom of FF collecting some kind of crud in memory or disk?
My old Safari (3.2.1) doesn't have any problems.
As far as I can see, both Firefox and Safari on my system use the same Adobe Flash Player.
So, this isn't a problem with Youtube, Flash Player, or my system, but a problem with Firefox (3.6.24) !?
Anybody (FF developers) have any ideas? I want to keep using FF!

Thanks Cor-el.
The problem existed in safe mode as well.
Changing Flash Player hardware acceleration had no effect.
The problem is gone now, after getting the standard youtube interface back.
What I'd like to know is whether any others who are unwitting testers of the new Youtube interface are experiencing problems, and, if not, what is their system? Which versions of Firefox and Flash Player are they using?

Firefox 3.6.24 (for Mac) hangs watching Youtube videos

Firefox 3.6 for Mac hangs (spinning wheel) while watching videos on Youtube.com. There is no problem selecting a video, but once a video starts to play, Firefox shows the spinning wheel if any mouse action is attempted. The video continues to play fine, but no mouse action can be taken. This happens with most, though not all youtube videos.
This started to happen a few days ago (late Oct?) after Youtube made cosmetic changes to its webpages. I am pretty sure that these changes are the cause.
'''Does anyone else have this problem?
Can anyone suggest a workaround?'''
System: 2009 MacBook Pro, 4GB memory
Notes:
My Safari - an older version 3 - doesn't have this problem. Of course, it doesn't show the new features of the Youtube pages.
I am up-to-date with Adobe Flash Player - version 10 - which I had before the problem began to appear. I cannot try version 11 because I don't have OS X 10.6. I've tried disabling "hardware acceleration" within Flash Player Settings, to no avail.
I haven't changed any of my plugins or extensions, except update DownloadHelper.
I tried a suggestion found in another post to no avail: increase the value of "browser.sessionstore.interval".

I found the cause and the fix !
Apparently, I had somehow "caught" the new Gray Youtube Interface - where the backrounds of all youtube pages are gray.
I cured that ailment by deleting all youtube cookies.
Now I have the old youtube pages, and no more hangs !
Isn't there anyone else who experiences hangs with the new youtube interface?
I don't want Youtube making my Mac act like an expensive paperweight.

Want to record edit and burn dvds of videos from canon camcorder what is the best way

what is the easiest way to transfer recordings from my canon camcorder hd to dvds after editing. The new imovie does not have idvd on it to burn dvds.

I'm assuming you're editing in iMovie? If you still have an older retail version of iLife, you can use that to install iDVD - I am using it with mavericks. Or, the retail 09 and 11 iLife disks are still available at some online resellers. The best thing out there still is iDVD with its customizable menus, themes, etc. However, there are other options for just burning: one good ons is Roxio Toast; then there is the free app Burn (basic I'm told, but works). Or google for others. Personally, I'd get iDVD.
The new iMovie (or the older versions) did not have iDVD built in - it's just a link to the iDVD application. FWIW, I prefer to use the older iMovie versions because they have more quality options to choose from when exporting. With the new iMovie, choose to export to file and choose your recording size and then you can drag that file into a burning app (or iDVD if you get it).

I have Mozilla Firefox and Adobe Flash Player 13 Plug-in won't allow me to watch YouTube videos

Up until last week I had IE9 and was able to download and watch YouTube videos with my son and play Facebook games. Then one evening I tried to pull up a Yo Gabba Gabba video on YouTube and the video window was blank. I had watched this video the night before with him, and the only thing I can think of is there was a Flash Player update that tried to download. I saw several posts that suggested downloading a new broswer, but I waited for 3 nights thinking it was just a glitch. I finally gave up and sent a pm to one of my friends who is a Internet Service Technician. She told me to download Mozilla Firefox, which I did, and the problem seemed to be solved. I was once again able to download and watch YouTube videos, as well as play games on Facebook. And it seemed my pages, pictures, etc. all downloaded 10x faster. That worked until the next evening and suddenly I once again could not download and watch YouTube videos.
I checked my system and it found that Adobe had done an automatic update so that instead of just having Adobe Flash Player 13 Active X I now had Adobe Flash Player 13 plug-in. I also noticed that Adobe Air was downloaded on my computer. I went in and uninstalled the Adobe Flash Player 13 Plug-in and I was once again able to download and watch YouTube videos. But when I tried to play games on Facebook I was told I would need to install at least Adobe Flash Player 10.0.2. I went to find that or an older version but each time I tried to download from Adobe I would get the Adobe Flash Player 13 Plug-in version, and once again I was unable to download and watch YouTube videos. I was, however, able to play the games on Facebook again.
Remember when I just had Adobe Flash Player 13 Active X I was able to do both while having Mozilla Firefox. I have looked all over the internet and I cannot find recent articles that talk about this problem. Can someone please tell me what I can do so that I can keep Mozilla Firefox, as it is 10X faster than IE9 and with Firefox my Facebook doesn't crash all of the time? But I also want to have the ability to download and watch YouTube videos with my son, as well as the play games on Facebook.
I should also note each time I went to uninstall Adobe Flash Player 13 Plug-in I received an error message saying there was a conflict with Mozilla Firefox and I first had to shut it down before the uninstall would proceed. Also, I received a reply on Adobe's Facebook page from a Tech who had me check to see if I had the latest version of Flash Player. I did have the most recent version. He then asked me to go to my add-ons and enable Shockwave. I followed the instructions and it was already enabled (or it said always activate). Neither of those helped me be able to download and watch YouTube videos. But I can still play Facebook games.

Hello,
My MacBook is crashing when I watch Youtube videos. Safari and Flash Player are updated.
What is the problem?
It will be necessary to take him on a technical assistance?
thank you

Have you tried an alternate browser to see if the same issue happens? Try Firefox or Chrome. Chrome has Flash embedded in it, so if it doesn't work, it's probably not a Flash issue. FIrefox is at http://www.mozilla.org/en-US/firefox/new/ and Chrome is at https://www.google.com/chrome .
Another thing to try is to sign up for HTML5 video from Youtube. See http://www.youtube.com/html5

Firefox (3.6.10) is very sluggish/slow and hangs up

All of a sudden Firefox (3.6.10) is very sluggish/slow and hangs up
I've been using Firefox (very actively) for over a year now and all of a sudden (yesterday) it began to act very sluggishly. On sites I have always visited frequently it hangs up for periods of 15-90 seconds or more, won't scroll down, won't open hot links, slowly opens new tabs ...
I rebooted my PC (multiple times), powered down my modem and router, ran a Norton disk optimization - essentially making sure it was not an outside factor effecting Firefox's performance. (Note: I am using a cable connection.)
I then ran a side by side speed comparison with Internet explorer (on my 2nd monitor) going to the same web sites, and IE had no problems/hang-ups.
FYI I only have a couple of add ins/extensions (Java, Microsoft Framework, Norton, No Squint, & RealPlayer) and none of those are new within the past few weeks at least.
Any ideas on what could be causing this? How to fix? (As I much prefer Firefox to any Microsoft product.)
Thanks.

Yes, FF gets sluggish from time to time. Sorry but it's the fact! FF also cannot render some websites properly (especially v3.6.10). I'm a big fan of all Mozilla software but FF 3.6.10 makes me very disappointed.

Same problem on my ipad mini, running ios 6.0.2.
A bit more info:
-tried using YouTube in Safari on another ipad. Worked fine.
Tried reboot (sleep + home buttons for 15 seconds). Didn't fix.
-tried logging out of my YouTube account, thinking the problem was tied to my settings. Didn't fix.
-tried uninstalling all apps I downloaded since the last time YouTube worked properly. Didn't fix.
-tried watching a video in desktop mode. Can tap video screen to bring up pause okay in that mode.
There are work arounds, but the thing I want to know is why YouTube doesn't work in Safari as of a couple of days ago, and is it indicative of another more serious problem with my ipad.

Macbook pro won't download adobe and won't let me watch youtube videos

i just got a macbook pro for christmas and it won't let me watch any youtube videos. it tells me to get the latest adobe flash player. I've tried downloading it multiple times, but it still won't work.. Help!.

Hey there, the exact same thing happened to me last night except for not being able to download adobe. Just make sure your connected to the internet(I know you probably are) and try downloading. I don't have an answer as to why you may not be able to download anything but for what it's worth, if you get to download adobe - install adobe then I close everything, restart, then it will all work
I hope this helps you my friend

Can no longer watch Youtube videos anymore Firefox 3.0.3 mac os x 10.4.11

Can no longer watch YouTube videos all of a sudden. Firefox 3.0.3 mac os x 10.4.11. Please help. Thank you.

Yes, thank you very much. The problem was related to the Flash plugin. It had been disabled by Firefox 'for my safety' apparently. No supported versions available any longer by Adobe for ppc macs - had to download an older version from an archive site - fixed the problem. No more crashes on Firefox or Safari while on Youtube.

Hello Amy.
This kind of issues are, unfortunately, more common and the we'd like. Thankfully, 99% of the cases are very easy to solve. However, you do need to diagnose what your exact problem is. Do this:
#run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe-mode] to disable all extensions, themes and plugins. If this fixes your issues, be them with RAM or CPU usage, then you know it's a problem with plugins, themes or extensions. Proceed to number 2. If safe-mode doesn't fix the issues, then read bellow, after this list;
#update all extensions, themes and plugins in your Firefox. If this doesn't solve the issues, proceed to the following number;
#disable all extensions, themes and plugins in your Firefox (not running safe-mode). Being certain that, as in safe-mode, the problems you're having have gone away, enable one plugin at a time. You should be certain that you WANT that plugin to be enabled, so keep your overall number of plugins as low as possible. When you encounter the problems, you know you've found a problematic plugin, so disable it for good. Keep enabling all plugins (except problematic ones) until you've gone through them all.
#enable one extension at a time. Again, be certain that you WANT that extension to be enabled, so keep your overall number of extensions as low as possible. Also, try the theme you want to have installed so see if that is what's causing the problem. When you encounter the problems, you know you've found a problematic extension/theme, so disable it for good. Keep enabling all your extensions (except problematic ones) until you've gone through them all;
#you're done! You've fixed your problems with problematic add-ons. If you want to keep using those problematic add-ons, please contant their author for support.
Ok, if disabling all extensions and plugins through safe-mode didn't work to bring Firefox's CPU and RAM usage to good levels, then you have different issue. The most likely scenario is that you have a third party software running on your computer that is messing with Firefox. Do as follows:
#try reinstalling Firefox. No data will be lost. You can get the latest version for free at [http://www.getfirefox.com/ getfirefox.com]. If that doesn't fix the problem, proceed;
#do a virus/malware check on your computer. If this doesn't fix it, proceed;
#disable all software running in the background that you don't want to have running in the background (in windows, this is done by pressing WINDOWS+R in your keyboard, typing "msconfig" (without the commas) and pressing enter. Now, under the "Startup" tab, you can uncheck the software you don't want, and reboot your system for changes to take effect. If you're unsure of what software you want running, ask someone with more experience). If this doesn't fix your issues with Firefox, proceed;
#check your firewall/antivirus/security suite for enabled functions/features that you don't want and/or may be conflicting with Firefox. You'll find that these features are most likely tied to Internet Security features, such as link scanners or URL checkers and the like. If you're not sure they are conflicting with Firefox, simply try to disable them to see whether or not that's true. As long as you don't browse the web with your antivirus completely off and your firewall completely turned off, there should be no problems. If this doesn't solve the issues, proceed to the following number;
#check your operating system security options, mainly advanced options that are not configured by default. While it's very unlikely that this may be the cause of the problem (after all, it's the last item on the list), it's remotely possible. If this doesn't work, proceed to the following point;
#update your modem/router software. There have been some reports that some modem/router software may cause Firefox and other browsers to loose performance and/or stability. If updating doesn't fix your issue, try other versions of the software, if possible. If you need support with this, contact your modem/router manufacturer. If this doesn't help, proceed;
#clean up your OS registry, using appropriate software. Make sure you've followed my instructions correctly, but if this all doesn't work, [http://support.mozilla.com/en-US/kb/Managing+profiles create a new Firefox profile] (this can be temporary, of course) and see if the issues persist. Report here the results, so we can't help you further.

Crackling and popping sound when playing music and watching youtube videos

there is a crackling and popping sound when i watch videos on youtube or play music/videos using vlc media player and windows media player. recently it has gotten to a point where it happens when windows is starting up or even when the laptop is required to play a sound for example when i plug in a removeable hardware such as thumbdrives

Hi @donnabail ,
Thank you for visiting the HP Support Forums and Welcome. I have read about your HP 2000 Notebook and getting a buzzing or popping sound while playing music and watching Youtube videos. Try performing a hard reset.
When performing a hard reset please note remove any and all USB devices. Disconnect all non-essential devices.
You can do a system restore. System restore will help if something automatically updated and did not go well on the Notebook that might have caused this.
You can try this
1. Right click the Speaker icon in the bottom right corner.
2. Click Playback Devices.
3. Click Speakers.
4. Click properties.
5. Click the advanced tab on the Properties window.
6. Change the Default Format drop-down to the highest quality.
7. Apply the properties.
8. Click OK to close the properties window.
What happens if you right click on the video while playing a video and take the check out of hardware acceleration. Shut the browser down and restart the notebook.
Have you checked for an update on the Active X.
Please let me know how this goes.
Thanks.
Please click “Accept as Solution ” if you feel my post solved your issue, it will help others find the solution.
Click the “Kudos, Thumbs Up" on the bottom to say “Thanks” for helping!
