What websites are giving you these problems? Is it all websites?

There are several types of players. Adobe Flash, HTML5 . . . . .

It's the Adobe Flash plugin and it affects all websites.Reloading doesn't help. The screen shows 'No report available' and I have no way to alert Firefox. Have no problem when using Window or Chrome to view video.

Thanks for your reply.

Window and Chrome and Firefox use different players.

Thank you so much for your assistance. Will look into it and in the meantime, will use Window or Chrome to view videos. Funny thing is I was able to do so before.

Sometimes when a clip is not working properly, I just download it and watch it later.

I don't think it's a problem with Adobe as I can still watch videos on Youtube but not some of the other sites. Worst thing is, when that happened, reloading didn't help and I couldn't even report it to Mozilla. Anyway, rather than downloading it as you suggested, I just switch to Chrome and be done with. Thanks for all your help.

Youtube currently uses the HTML5 player.

Try to disable multi-process tabs in Firefox. You can disable multi-process tabs in Firefox by setting the related prefs to false on the about:config page.

• browser.tabs.remote.autostart = false
• browser.tabs.remote.autostart.2 = false
