Windows 7: Preview-Thumbnails in YouTube’s progress bar Disappeared!

Preview-Thumbnails in YouTube’s progress bar Disappeared!

Hi,
well, this small "tooltip" preview-video-frame which pops-up while hovering the mouse over a point in youtube's video progress bar, (which helps to quickly navigate to a desired position on video storyline) suddenly, DISAPPEARED!
In fact, didn't disappeared at all, but it shows as a small BLACK rectangle frame. No preview!
I can't think of anything I did to might have caused that. :\
(May be a recent update of flashplayer for Mozilla FF).
Is there some remedy/solution to it?
thanks a lot.


PS. I forgot to check how it behaves with another browser.
So, in IE this small tooltip-preview-thumb works just fine! shows exactly the frame where I hover the mouse!
So, I guess it has to do with Mozilla FF? or, perhaps some wird "setting" in the Youtube's setting (i might have "touched" a bit without knowing...)
Is there perhaps, some Youtube setting for "enable/disabling" this preview feature?

Still, nobody has a suggestion ? ...

So, let me update the forum, that in my lonely attempts to FiX the problem, I tried to UN-RE-install the addon.
After UnInstalling the "NPAPI" Flashplayer addon for Mozilla, the missing preview-video-frame in youtube's videos RETURNED!!! although, the page recognizing that the missing addon was asking "If I want to install it"! but, the videos play just fine [even most responsive], and the preview frame is there! ... (the only present flashplyer addon, in the system, was the "ActiveX" one for IExplorer).
BUT, some pages with some active multimedia content, eg. with audio applet bar (with lay", "stop", "pause" buttons), do NOT even LOAD! like in this page :
????????? ???????, ????? ??????????

So, I tried to re-install again the latest fplayer NPAPI addon, but the preview-frame... again BLACK!

I even tried to clean install 2 PREViOUS versions of the FPlayer addon, the v21 and v20, but, the problem remained the same!

IF nobody has something else to suggest, I guess I'll have to try run FireFox in Safe Mode , though - needless to say - I have some fears doing that (that it may mess the whole system up)...

NOone has seen this thread/subject yet?

or, noone has any solution to suggest?



Anyway, I'll add something "odd" I observed:

this "mouse-over preview-frame in youtube's progress bar" does NOT show ONLY when a video is playbacked in Youtube's page;

But IF the very same video is played, eg. in Facebook page, or in a blog, it shows pretty well. !!!

I guess that might mean that the problem is browser not-dependant; isn't it?

weird...


Hope someone will think of some remedy to this

Your thread has over 160 view, so I'm guessing that those that viewed and are members are like me. Don't know the answer to your problem.

If I knew how to help you I would.

I use Firefox 47.0.1 and I don't have the problem you describe.

thanks for your reaction/answer (my comment was not offensive).
In fact, I'm using FF vesrion 30.0 and not intending on updating to the newest one, because after v.30 the "CoolPreviews" Addon stopped being supported and I have come to get used to it so much, that I cannot think of using a browser without this great functionality. (Haven;t found any real alternative to it, yet anyway; Nor in another of the major browsers).
But, I don't think the fact of using a previous version of the browser has anything to do with it, because I do so, since more than a year now, with no problem at all, so far. (Doing all the rest updates: Flashplayer, Java, etc.) Just about a week ago, this problem popped-up!
I guess there must be some setting in youtube's options (maybe for resources economy) that I haven't been able to discover.

UPDATE:
1. I Un-RE-Installed FireFox but the issue remained as it was : a Black mouse-over preview frame!
2. I just even tried running FF in Safe Mode as I was suggested by a friend.
Nope!!!
the "preview frame" in time-bar is STiLL BLACK.!!!

➤ The strange thing is that all work fine, if the youtube's video, playbacks EVERYWHERE ELSE
(eg.Facebook page, or in a blog), BUT in its own page...!!! Really weird!

Today, I tried something new:

Installed a new browser, "Pale Moon" which has the same open source code as Mozilla, and uses the same FlashPlayer type (NPAPI) as Mozilla. Not the "activeX" one, as IE.

Well, the problem is THERE TOO !!! : that mouse-over preview frame shows as a "black rectangle".

And AGAiN, this happen ONLY when a video plays in the Youtube's page, IF the very same video appears in any other page, the preview frame, shows just FINE.!!!

It has become a ...Puzzle.

1. I tried deactivating "Hardware acceleration" on Flash Properties (some suggested it helped them fix the same problem), but it didn't, in my case.
2. I cleared out "All Cache" from Mozilla browser (a few, suggested it was helpfull for them), but again, not here...
it's frustrating.

PS. I attach 2 snapshots:
1. shows the problematic black box instead of the underlying frame in Youtube's progress bar;
2) the same video, at the same frame eg. in Facebook (or elsewhwere), where it shows FINE !!!

Anyone ever get empty preview thumbnails?
On taskbar preview thumbnails, usually you get to see the content inside the window. Sometimes, however, and I'm unsure of the situation that causes it, the thumbnail will not be there, but you end up with just a blank box with the program's icon inside. The way to fix this is to make active that...
