Instead of the video, I get this in the video window-
This plugin is vulnerable and should be updated.
Activate Adobe Flash.
Check for updates.
I just did update Adobe Flash.
When I hit "check for updates", all it does is go to a Mozilla page that tells me my Shockwave Flash is up to date, but my VLC Web Plugin needs updating.
I seem to have the most recent VLC player. Wouldn't that have given me the Mozilla plugin, or is it something else entirely?
Why would it say Flash is in need of updating if Flash is fine but VLC is what needs updating? What would that have to do with YouTube?
Only thing I can think of is to reboot...again, and see if this time the new version of Flash takes.
Any ideas would be welcome...

Check Now (for updates).
Anyway this the steps if you have problem installing Adobe Flash player:
1. Download the uninstaller for Flash Player: http://download.macromedia.com/get/flashplayer/current/support/uninstall_flash_player.exe
2. Exit all browsers and other programs that use Flash, for example Yahoo! Messenger.
3. Run the uninstaller.
4 Verify that uninstallation is complete.
5. Restart your computer.
6. Download and install latest Flash player for Firefox: http://fpdownload.macromedia.com/pub/flashplayer/latest/help/install_flash_player.exe
7. Download and install latest Flash player for IE: http://fpdownload.macromedia.com/pub/flashplayer/latest/help/install_flash_player_ax.exe

Okay, here's the weird part.
I installed the new VLC, as mentioned. 2.1.5.
I downloaded and installed the lastest Flash player from Adobe.
Rebooted the computer.
YouTube is working fine again.
The advisory page at Mozilla is still telling me my VLC plugin is at 2.1.3, and needs to be updated. I've refreshed the page again and again, but it keeps giving me the same report. How can I have VLC 2.1.5 but have the VLC 2.1.3 plugin for Mozilla?
Where Mozilla says it wants it?
Its just plugin version check
Its doesn't mean Mozilla wants VLC Web plugin
VLC Web plugin its no use in Mozilla Firefox
VLC Web plugin basically for open media files in browser, but Firefox already can open media files without any plugins
you can remove it by run Install VLC, select add/remove components and deselect Web Plugins:
Or you can disable VLC Web plugin in Firefox by selecting Never Activate
or just disable Firefox plugin update check.
add text to your user.js:
// Don't show plugins update tab on startup
You can change it per about:config, but often Firefox reverts that at startup. Putting the text in user.js seems to work better.
I use old Flash 11... no trouble at all.
In fact, this isn't coming from the automatic updater but from the extensions blocklist. See https://support.mozilla.org/en-US/questions/949746 for how to disable it.
Personally, I have doubts about the advisability of this kind of feature. I know the Mozilla guys are aiming to ensure security, but the issue is that it is impossible for the user to tell where the message is originating from, or where the 'click to update' link will take them, as it doesn't show any URL in the status bar. User-duping (social engineering) is more commonplace than sophisticated software exploits, and this situation of a mysterious message popping out of nowhere just begs to be exploited with a fake version of same. If it hasn't been already.
Weird thing is this only came up because I couldn't get YouTube videos running. The text in the YouTube video screen took me to where I saw the Mozilla plugin check.
I updated Flash and now all's well, but that same plugin check shows the VLC plugin apparently IS on the computer, as part of Firefox. It gives it the version number 18.104.22.168, and says it's vulnerable and needs to be updated. (The button says "update now".)
Is it really safe to just leave it as it is?
Yes its safe
Again as I write before: https://forum.videohelp.com/threads/368913-Firefox-won-t-play-YouTube-vids-Plugin-is-vu...=1#post2362104
In general I would advise deactivating all unnecessary browser plugins. Or, set them to click to activate mode. The two most vulnerable are the Adobe Reader plugin and Sun/Oracle Java, and perhaps surprisingly, neither are EVER needed on the vast majority of computers.
The two greatest risks these days are 'You need to update your plugin' message spoofing, and the browser being pwned through a malicious embedded document that exploits a vuln in a plugin. Therefore, to be secure, disable all unneeded plugins.
I have used VLC for years and never even tested the plugin.
I got this message as soon as new update came for Firefox.
When you go to the site with video there will be a RED camera next to a web page. Click on it and window will come up where you can click on to allow the plug in to work.
A simple refresh on YT page will bypass this small hiccup.
There's a Fake Java running around for years now; to watch out tho.

Something is still broken. No youtube vids will play using latest flash update 22.214.171.124 in Firefox. Tinker...no red camera shows up either.
Did this to fix: Disabled hardware acceleration in Firefox.
Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

I had the same problem today. Firefox says Flash needs updating but when I tried to update it, it tells me it's up to date. So I used the Flash Player shortcut in Windows Control Panel to open the Flash player settings and I updated it from there. That worked, except I ended up with two listings for the Flash player plugin in the Firefox addons list..... the previous version and the new version. Uninstalling Flash completely via Add-Remove programs and re-installing it again fixed that issue.
I hardly use Firefox these days. It was an accident I used it today. I've been browsing with Pale Moon instead. It didn't nag me to update the Flash plugin as Firefox did, or disable it. I switched to Pale Moon when the Firefox GUI was "updated" to make it look like Chrome, so I still have Firefox version 28 installed. Maybe my Flash updating problem was due to having an old version of Firefox.....
If you have Flash instal in your computer, I think it work for any browser you use, equally.
I don't think any updates of flash are any important, so I disable them, and no problems here.
- If the Flash file (or any other file) got corrupted for one reason or another:
I erase the short-cuts, etc. and just reinstall the same .exe file I already have and in most of the instants it work like a champ.
Except on some browser-exes, where the authors have to much control on what you are doing with it and screw you up LIVE. Then I need a real fresh .exe
I also use Pale Moon 'cos is light & fast. (I learn how to control "ctfmon" too)
Firefox is too heavy duty.

I've used both browsers a lot, and while admittedly my internet connection is fairly slow, I've never thought one is faster than the other. I have the same extensions running in both browsers. Browsers are generally fast enough for any speed differences not to mean much.
Mind you I've never really been concerned about benchmarks. Back in the days before Firefox, I used MyIE. It was one of the early tabbed browsers (IE rendering engine). Even if at the time MyIE had benchmarked much slower than IE I wouldn't have cared. I could open a link in a background tab using MyIE by middle clicking on it. The IE equivalent was right click, open in new window, then the inevitable annoyance of having to minimise the new window because it opened in the foreground and got in the way of what I was doing.
Even today I'm running about 25 extensions to make the browser more usable. If I'm on someone else's computer running a vanilla install of any browser I get frustrated fairly quickly. Is there a benchmark which includes the speed difference between highlighting text, copying it, opening a new tab, loading Google, and pasting the text in order to search, compared to highlighting text, dragging it up a little (mouse gesture) and having a Google search on the text open in a new tab. That sort of thing.....
...Nevermind. I restarted Pale Moon again and the video now plays.
EDIT: I think my Firefox days are over.
It is an add-on for firefox, etc.call:
You Tube Flash to HTML5
Quick Youtube Downloader. I just have to remember to turn it on when I access youtube.
Also, I used Pale Moon all night last night with 10 or 15 pages opened and Photoshop with 4 or 5 files open with over 20 layers for each file and Pale Moon didn't start showing signs that it was going to crash til around 5:00 am when my night time free bandwidth usage from my satellite carrier expires. Firefox would've crashed multiple times during the night. I just hope that Pale Moon doesn't screw their browser up like Firefox has.
Before: We just to be just download the browser. Now they want to know who download it.
On top of that:
They are like the "New NSA" ... they know what we are doing and start messing ( "blocking/sensor" ) with the browser - As we go, they go. - til can't be used it anymore.
...even they send you warning messages like: Erase your bookmarks, etc.
Then is time to uninstall and download a new Pale Moon from fresh, with diff. credentials.
The Browser are the "New Rulers of the Internet" ...if you ask me.
I can't wait to see the new P2P-Browser is coming soon or hopping for a "Roulette-Browser" to be created in the future.

Guys, since this has totally deviated from the theme of the thread, let me throw this in-
As mentioned above, THE PROBLEM HAS BEEN SOLVED. Firefox is fine, YouTube is fine, and little birdies are singing.
I don't know why some of you are having problems with Flash Player in Firefox (and thus YouTube), but if someone with my limited knowledge got everything working...come on. You've GOT to be able to.
