Mozilla Firefox or What?

For a while now, YouTube's video player gets messed up if I switch back to the YouTube tab or if I scroll up and down the page on the YouTube tab.

If I switch to another tab and then back or scroll up and down, it fixes itself or stays messed up, but it usually does fix it.

Would that be Mozilla Firefox or something on my computer? It's not too big of a deal, but I would like to know why it wasn't doing it before. I don't remember exactly when it started, but it wasn't always like this.

Thanks.

 

I have the same thing happen to me. It's not Firefox, it's Flash. I also have an issue where Flash freezes my browser on occasion.

You could try re-installing Flash.

 

Happens to me too. I haven't noticed it since I opted in for the YouTube HTML5 beta, though, but then again I don't spend much time on YouTube.

 

It's a problem with Flash.
Currently, there is no solution to fix it, so I suppose you'll have to deal with it until they release an update.

 

I'm actually in it.

So did Flash recently update? Because it was fine before.

 

It's been a long standing issue, it's not really a huuuge deal though so it's not too bad.

But as it stands now there's no fix.

 

I believe so, I mean, my flash called for an update when I turned it back on Thursday...
