When will I learn that once I find a version of FF that works, not to update it? I was working with v20 for a long time, and it worked fine. Decided to update to latest version, and BAM! Videos don't play.

Tried safe mode, still same thing. No videos will play. Was fine this morning, but tried to watch CNN video and it would not play. Spinning circle just jumps around, doesn't spin. YouTube won't play either.

Portable version from Portable Apps works fine.

The Portable version of Firefox 26 works? That implies that there's an issue with your settings in non-portable Firefox 26.

Edit: I do read, but sometimes I read too fast. Ignore the Safe Mode suggestion.

Is there anything special about how your non-portable Firefox connects? Please check:

orange Firefox button (or Tools menu) > Options > Advanced > Network "mini-tab" > Settings button

The default is "Use system proxy settings" and you might also try "No proxy"

If you use extensions (Firefox/Tools > Add-ons > Extensions) that can block content (e.g. Adblock Plus, NoScript, Flash Block, Ghostery) then make sure that such extensions aren't blocking content.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

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

Thanks, but I'll just use the portable version, which actually works. I get a little tired of trying to make FF work properly sometimes. For some reason, portable works fine no matter what add-ons I use, so I'm glad there is that option.
