I've read that there is a Firefox add-on, or plug-in, that will disable the maddening autoplay that has just recently started to occur when I play YouTube videos.. can I truly disable this thru Firefox?

It's certainly possible that Youtube has changed something...
Since most volunteers here probably aren't using this extension, I suggest contacting its author using the contact information on this page: https://addons.mozilla.org/en-US/firefox/addon/smartvideo-for-youtube-mytube/

My images will not show in the Finder Pictures folders, but just display as jpeg thumbnails. I have to open each one to see what photo it is. This has just recently started to happen.

I made sure the 'Show Icon Preview' box was checked. This is about all I can do, really, Frank, as i don't know enough about the workings of these machines to start fiddling about.
Strangely the images show as previews in some folders, yet not in others, even though they come from the same sources (my camera and my phone).

My App Store icon keeps displaying the little red circle with the number 4 and when it is opened to the updates tab there are no app to update. The page displays "All Apps Are Up to Date". This just recently started an occurs on both my iPad2 and iPhone5

Why is this happening?

I've seen reports of this happening when updates have been issued for apps that make them only work on iOS 7, users of earlier versions of iOS get notified that there are updates pending but when you actually go into the app store updates function it realises they don't apply to you because you are on an earlier version of iOS than what the new versions require.
In fact I just had a very similar experience on my iPod touch with iOS 6, in App Store app it flagged 7 app updates in red badge but when I clicked on the Updates button it only listed two apps to update, once they'd been applied the outstanding updates badge disappeared.

There has been a change in where Firefox searches for plugins and the plugins folder in the Firefox program folder is no longer scanned for plugins, so Firefox won't find them anymore if they are installed in the plugins folder instead of the "browser\plugins" folder that Firefox now scans.
You can set the plugins.load_appdir_plugins pref to true on the about:config page to make Firefox scan the "<install>/plugins/" directory for plugins like the WMP plugin (np-mswmp.dll).
You can alternatively move plugins from "<install directory>\plugins\" to "<install directory>\browser\plugins\" (create this folder when missing) to make Firefox find them again.

Thank you for replying. Unfortunately, I already did all of these things. As you can see from the below screenshot, the language is already set. Also, this screenshot was taken in Safe Mode, so NoScript is not enabled. About:accounts still says I need to enable cookies for some reason. So, this solution didn't work....

Youtube videos are working on IE but in firefox only audio works. How to resolve this?

I can hear only audio when I try to play youtube videos. I am not aware why all of sudden this started happening. Please guide me on the same.

Starting in Firefox 37, YouTube will default to the built-in HTML5 video player in Firefox. When you visit the following page, normally 5 of the 6 tiles have a checkmark on a blue background, and one exclamation point on red:
https://www.youtube.com/html5
And it says "The HTML5 player is currently used when possible."
Do you see that?
''If yes:''
It's possible that one of the components used to decode the video is not working properly. When you right-click the video, a custom menu should appear with a selection called Stats for nerds. Do you notice any kinds of errors mentioned there? I have attached an example for reference.
''If no:''
Then YouTube is likely still using the Flash player. You can confirm by right-clicking the video and looking for references to Flash on the menu.
''Note: If Firefox's right-click context menu appears in front of a site's menu, you can tap the Alt key to clear Firefox's menu.''

Answers in this forum have shown different things have worked for different people.
For some clearing YouTube cookies and the cache solved the problem. For details of how to do that see https://support.mozilla.com/kb/Deleting+cookies and https://support.mozilla.com/kb/How+to+clear+the+cache
Others had to go a step further after deleting YouTube cookies and block YouTube from saving cookies. In the Tools menu select Options to open the Options window. Go to the Privacy panel and make sure it is set to "Use custom setting for history". Click the Exceptions button, type in http://www.youtube.com and click on Block
Another option is to disable hardware acceleration for Flash. To do that right-click on a Flash video, select Settings, go to the first tab of the settings for the option to enable/disable hardware acceleration for Flash. This is something recommended by YouTube for those having problems - http://www.google.com/support/youtube/bin/answer.py?&answer=1209379

I have windows 8.1 and firefox won't play youtube videos but IE will

I have windows 8.1 and firefox won't play youtube videos but IE will. I have tried reinstalling firefox, flash, java. Resetting firefox don't help, disabled hardware acceleration, protected mode 0 in the mms.cfg file. Nothing will play on youtube in firefox. It says "an error has occured, please try again later". The ads play fine though. Everything plays fine in IE. I have tried different versions of flash also with no luck. I even restored the system to a previous iso image with no luck. Does anyone have a solution?

It maybe because your javascript is disabled .
You can check the javascript.enabled pref on the about:config page.
http://kb.mozillazine.org/about:config
There are also extensions that can block JavaScript or otherwise interfere.
https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
Or,
"Clear the Cache":
Firefox > Preferences > Advanced > Network > Cached Web Content: "Clear Now"
"Remove Cookies" from sites causing problems:
Firefox > Preferences > Privacy > Cookies: "Show Cookies"
Start Firefox in [https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Safe Mode] to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

Why won't Firefox for Android on my Kindle Fire HD play YouTube videos?

The default browser (Silk) on the Kindle Fire HD plays YouTube videos. Both Firefox for Android and Silk obviously use the same operating system and hardware. What needs to be done to/with the Firefox for Android browser so that it will play YouTube videos. Firefox on my desktop machine plays YouTube videos.

There is the old insecure Flash 11.1 Plugin that Adobe (and Google Play) has not supported since Android 4.0. As long as you have Android 4.3 or older then you can get the Flash plugin to work in manual install though Android 4.4 has made it so Flash will not work.
However Mozilla has made a workaround for Flash can still work in Firefox on Android 4.4 in as early as Firefox 27.0 if I recall.
There is this thread on getting Flash installed however the poster mentions Dolphin and not Firefox instead.
http://www.amazon.com/forum/kindle?_encoding=UTF8&cdForum=Fx1D7SY3BVSESG&cdThread=TxTR71JR4GVXQM
Not that some sites (News sites are among some I encountered) have since lately been requiring users using Flash 11.1 on Android, PlayBook and Flash 11.2.x on Linux to upgrade to more current (not possible) to view their Flash videos.

Firefox will only play YouTube videos up to 720, how to fix?

This afternoon I watched an old video of mine on YouTube. Afterwards, YouTube now only gives the option of 360 or 720p playback. Internet Explorer will play the same videos at 4K, and I was able to watch 1080 up to 2160p before watching this old video, how do I fix Firefox?
http://youtu.be/Je0sQwVynzI
There's the newest video, with a 4k playback option, I don't want to post the old video that caused the glitch but it's the first video in my channel.
Please help!

After going into about:config I did 2 things:
media.mediasource.enabled set to True
then added
Right-click and select New > Boolean
Name preference media.mediasource.ignore_codecs
Set value to True
A ton of technical stuff just from playing an old video! Is there a simpler to fix this without hard setting things in the configuration?
And now I cannot replay youtube videos! It will pause if I try to go back. Considering a video will auto play so I will select the highest quality then scrub back to start this happens usually every time so this fix is worthless.

Frostbitblue,
in Safari’s Preferences, select its Security tab, and make sure that its “Internet plug-ins: Allow Plug-ins” checkbox is checked.

A couple of things:
* Upgrade to Firefox 13 (you're currently running 12). Select Firefox > Help > About Firefox to upgrade.
* Check if your Flash plugin is out of date on this page: https://www.mozilla.org/en-US/plugincheck/. If it is, follow the instructions on the page for upgrading Flash.
Hope this helps!

Once I've saved a PDF document in Adobe Reader is there a way to add additional documents later?

Once I've saved a PDF document in Adobe Reader is there a way to add additional documents later?
If not is there a way to combine lets say 100 documents into another PDF file at once (Batch export) in PDF Pack software or do I have to add each document one by one drop and drag style?
Thanks

What has this got to do with Photoshop?
In Acrobat Pro one can combine pdfs (Combine Files into PDF) and Photoshop (not in CS5, but again in CS6) offers File > Auromate > PDF Presentation to combine Photoshop files in one pdf.
