I have a question.

Back then, whenever anyone post a Youtube video, it would show up. Nowadays, it wouldn't show up and only a blank space shows up.

As you can see inside the spoiler, only a blank space showed up. Anyone can offer a suggestion of what I should do?



Additional info: I'm currently using Firefox on a Macbook.

I can see the image. Can you see it?

What's the name of the song in this spoiler?

Try restarting with add-ons disabled. Firefox button > Help > Restart with Add-ons Disabled... If it works in that mode, it's one of your add-ons...

I can't even open the spoiler

Hmmm, weird. Try clearing cache and do what platonic fuzz told you to do.

Did that several times, doesn't work.

[EDIT] I've been here long enough to understand how to clear cache and everything when a bug hits fakku you know...

Is the same on Chrome or Pale Moon?

It's actually working fine on chrome. What the fuck?

try updating Firefox...

or try using Palemoon...

Maybe it's Javascript?

try using ccleaner or resetting the browser setting

You can try resetting Firefox entirely: Firefox button > Help > Troubleshooting Information > Reset Firefox

Just beware that you'll lose all your customizations to Firefox by doing this. See here http://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems to see what will be saved and what will be removed.

After you reset, you'll have to reinstall Flash Player for Firefox.
