I find Firefox won't load youtube vids (black screen; altering url to https, can view) . Tried restarting laptop and un/re-installing Flash to no avail, why is this happening?

Livestream and wikipedia pages also appear strange
Dell laptop
Problems started today, no idea what the cause is

Youtube works OK for me on Chrome, Opera, Flock and IE8 but not Firefox. I have tried reloading / updating Flash etc but to no avail.
Usually it will start to play a video and then within a fraction of a second the control bar will disappear and the black screen covers everything and sound and vision are terminated.
The hpps dodge does not work either.

My iphone 4 has switched off by itself and won't switch back on. The battery wasn't dead, I have tried restarting it and have tried to put it into recovery mode but it still won't switch back on?

Try a reset, hold down the home/sleep button together until you see the apple logo and then release, then wait for the phone to boot back up.

My Firefox won't load any websites, but other web browsers will. I have tried following the proxy help to fix this, with no luck. What can I do next?

Any website I try to visit using Firefox won't load, it just keeps saying that it is unable to connect. I tried other web browsers, and they work no problem. I tried following the proxy steps provided, but did not help.

Did you check your security software (firewall)?
A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.
See [[Server not found]] and [[Firewalls]] and http://kb.mozillazine.org/Firewalls
If you use a Firefox 4 beta release then you should create a new profile exclusively for the 4.0 beta version and create a desktop shortcut with -P "profile" appended to the target to launch that profile.

Hallo, my Firefox browser wont load youtube for some reason, the explorer will. I have tries to change the proxy setings as the firefox help center suggested, but to no avail. Also no updates were installed on firefox that I'm aware of. pleas help me.

Hallo,
For some reason firefox has stopped loading the youtube site for me. I can watch videos other people uploaded to facebook for example, but cant get into the site. the explorer will load the site, so I've tried changing the proxy settings in my firefox as recommended in the help center, but to no avail. Also there was no update installed that I'm aware of, getting to youtube through any link will simply give me an error message saying the connection was reset while the page was loading.
pleas help me.

I had trouble with youtube and cleared all history and cache. This cleared up the problem(s).

Firefox keeps closing out hotmail with out warning at all in CA., U.S.A. plus will not close out since 2 weeks ago now ,why is this happening and when will it be fixed? S.A.

why is firefox not allowing hotmail to be used the last 3 weeks?
I keep having my service shut down plus will not allow singing out all the way. is there any plans to fix this problem ? how soon will you fix this problem.
you are way better than internet explored and they are not doing these things so why are you allowing these problems to keep going on?
thank you for getting this fixed and back to normal A SAP.

Hi systemBuilder, you are not alone in your frustration. The problem is the plugin model: plugins are allowed to do much more than they can be trusted to do intelligently. Without a change to that, Firefox cannot stop the Flash player from changing window focus.

Firefox won't open after update, black screen, beep and "do you want to allow program to make changes..."

Updated Firefox yesterday and now the program will not open on my desktop. Screen goes black for a second, issues a beep and then get box asking if I want to allow Firefox to make changes to my computer. Does not matter if I click yes or no, box disapears and nothing happens. Willing to remove and reload the program but hate to lose all my bookmarks.

'''Try the Firefox Safe Mode''' to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.''
''(If you're not using it, switch to the Default theme.)''
* You can open the Firefox 4.0+ Safe Mode by holding the '''Shift''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Don't select anything right now, just use "'Start in Safe Mode"''
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again.''

Why wont my mac book turn on completly it just shows the start screen and under the appl theres a bar that keeps loading and when its done it just powers off why is this happening??????

Why won't my macbook air turn on completly just at the start up page and under the apple logo there's a bar that just loads and when its done loading the Mac just powers off this just happens over and over I'm afraid if I do any thing my pictures will be lost on the computer ???

Hi jasonfromforthworth,
Thanks for the question. If you have updated to Yosemite, then the Apple Logo with the status bar is the expected behavior for when the computer starts up. However, the powering off is not supposed to be happening ... so here are some steps to take if your MacBook Air won't turn on.
OS X: What is Safe Boot, Safe Mode? - Apple Support
http://support.apple.com/en-us/HT201262
Starting up in Safe Mode
Follow these steps to start up into Safe Mode.
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup sound, press and hold the Shift key. The Shift key should be pressed as soon as possible after startup, but not before the startup sound.
Release the Shift key when you see the Apple logo appear on the screen.
After the Apple logo appears, it may take longer than usual to reach the login screen. This is because your computer is performing a directory check as part of Safe Mode.
To leave Safe Mode, restart your computer without pressing any keys during startup.
Troubleshooting: My computer won't turn on - Apple Support
http://support.apple.com/en-us/TS1367
This article discusses what to do if your Mac won't turn on. To differentiate this from a display issue, be sure that when you press the power button:
You don't hear a startup chime.
You don't hear any fan or drive noise.
There is no video on your built-in or external display
If your computer has power but doesn't display any video, it may have one or more of these similar symptoms when you press the power button:
You may hear a startup chime.
You may hear fan or drive noise.
You may see a light from the Sleep LED (if your Mac has one).
Pressing the Caps Lock key on the keyboard causes it to light.
If any of these display-related conditions occur, see Troubleshooting: My computer has no video instead. Otherwise, continue with this article.
If your computer won't turn on, try each of these steps:
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
Reset the SMC.
If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).

Firefox won't load web pages all the way, what can I do to fix this

I have this problem where firefox won't load any webpages all the way and if I try refreshing the page it shows some of the webpage but not the whole thing....and now it won't load any images either. I have tried everything that i could think of and nothing works. I can't watch anything on youtube or go on facebook and google won't work either.

There seems to be something of a pattern in that those are all secure sites (HTTPS address). Have you noticed any certificate errors recently that you might have solved by adding an exception, or does everything seem normal otherwise?
Here are the usual things:
When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
Alternately, you also can clear Firefox's cache completely using:
"3-bar" menu button (or Tools menu) > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now"
If you have a large hard drive, this might take a few minutes.
(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:
* right-click and choose View Page Info > Security > "View Cookies"
* Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"
In the dialog that opens, you can remove the site's cookies individually.
Then try reloading the page. Does that help?
In case one of your extensions is involved, could you test the page in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using either:
* "3-bar" menu button > "?" button > Restart with Add-ons Disabled
* Help menu > Restart with Add-ons Disabled
Not all add-ons are disabled: Flash and other plugins still run
After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (''not'' Reset).
Any difference?

Firefox won't load google image search results

Firefox won't load google search results. It will load the page of results with the thumbnails etc. but if you click any of them, just a loading spinning icon appears on the tab and it never loads.
I have tried:
Both logged in and out of google account,
All other areas of google work with no problems (news, shopping etc.),
Site working perfectly in Internet Explorer,
Running firefox in safemode,
Manually disabling all plugins and addons,
Clearing the cache and cookies,
Opening results in new tab just results in white page with web address but it never loads,
Restarting both my PC and router.
It's not been working for at least the past 6 hours. Last time I used it was about a week ago and it was working fine then. I've not noticed any problems on any other sites this week that I can recall.

Updating firefox to version 17.0 appears to have solved this.

I just updated to 3.6.11 and now firefox won't load any web page

I just updated to 3.6.11 and now firefox won't load any webpage it
just times out I tried diableing add-ons no difference. I't on internet exploers now. Tried rebooting.

Do you use McAfee Antivirus/Firewall/Security products? McAfee released a security update that is blocking Firefox 3.6.11. This should be cleared up with the next McAfee update.

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.
'''''Do NOT click the Reset button on the Safe Mode start window.'''''

Images in firefox won't load on android

images in firefox won't load on android. there is no option to click to download images - there is nothing in the image boxes at all.

Can you please update to Firefox 19?

Firefox won't load pages and says "Stopped" in the lower left corner of the screen.

From last night "Latest FF and XP Pro. 2.4 Ghz Celeron, 1 gig RAM. FF will work for a while, then it will stop loading pages and say "Stopped" in the lower left corner of screen. Sometimes I can refresh and the page will load, but 95 out of 100 times I can keep refreshing and it will say "Stopped". Or, the page will partially load and then quit and say "Stopped". I have disabled IPv6 and DNS Prefetching and it is still doing it. IE is doing about the same thing. VERY frustrated. My last PC started doing this and I finally upgraded to a newer one and it was fine for a couple months, but started doing the same recently. Arghhh ... Thanks!"
Thanks to you who replied last night/this morning. I hit the "solved" button apparently but this from last night-
https://support.mozilla.com/en-US/forum/1/702910#threadId703008
is not solved. I tried FF 3.5.9 and still have the same problem.
Thanks again,

== This happened ==
Every time Firefox opened
== a while back

You, me and many others (based on threads throughout the net) have this same problem. I've had some peeps at Mozilla take a look, they couldn't find a problem or a solution.
Here's what I found does work - The problem popped up on me when I upgraded to Firefox 3.63. Uninstall FF 3.63, and install 3.59. You can still download it until end of June or July I think.
My problems went away with 3.59. Seems to only affect Window users as Mac Firefox 3.63 works fine.
Also found some threads pointing to ZoneAlarm Firewall, timeout handlers and some upload tools. I don't have ZoneAlarm so I don't think that was the cause, just another victim.
I wish Mozilla would pull the plug on 3.63, re-package 3.59 as 3.64 and go back to the drawing board until they find out whats wrong.

Firefox won't load pages, but other browsers will.

Firefox won't load any internet pages, but different browsers, both Chrome and Explorer work, I havent tried others. I've un-installed, changed the name of the folder of the plug-ins that were left so it wouldn't recognize them, then re-installed nothing happened. I've checeked for viruses, proxies, and i'm pretty sure its not a firewall, I think we only have one and I checked it, plus there is no prompt asking me if I want to allow firefox to access the internet. It won't run in safe mode, so its not any add-ons, clearing the cache didn't do anything either. Its also not in offline mode. What else could it be?

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

Ever since installing a VPN (astrill), Firefox won't load webpages until Astrill is connected.

I installed a VPN, Astrill, and since Firefox won't load webpages unless it is on and connected. Once the initial connection has been made, I can turn off the VPN and firefox continues working. I'm on a windows 8.1 operating system. Has anyone had similar problems?

Try going to your Add-ons > Extensions, and disabling the Astrill extension.

I find Firefox won't load youtube vids (black screen; altering url to https, can view) . Tried restarting laptop and un/re-installing Flash to no avail, why is this happening?
