Hello,

Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:

1. (Firefox 57 and above) Click the Library button and choose History.
   (Click the menu button and choose History in older Firefox versions.)
2. In the History menu, choose "Clear Recent History...".
3. Under "Time range to clear", select "Everything".
4. Now, click the arrow next to Details to toggle the Details list active.
5. From the details list, check Cache and Cookies and uncheck everything else.
6. Now click the "Clear Now" button.

Further information can be found in the Delete browsing, search and download history on Firefox article.

Did this fix your problems? Please report back to us!

Thank you.

Hello iamjayakumars!

Thanks for your reply. Unfortunately, clearing the cache and cookies did not solve the issue.

I went to my old internet explorer browser and this issue does not come up. I am able to load more videos..along with all the ads.....

I also tried disabling ad block in Firefox and the problem still exists. I disable Java via Windows control panel and still nothing.

Any other suggestion would be welcome.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block (wanted) content.

• make sure your extensions and filters are updated to the latest version

Firefox shows the shield icon at the left end of the location/address bar in case Content Blocking is blocking content.

• click the shield icon for more detail and possibly disable the protection

You can check the Web Console about what content is blocked

• "3-bar" menu button or Tools -> Web Developer
• https://support.mozilla.org/en-US/kb/tracking-protection

Tried everything and nothing works. I think I will switch to Chrome as my browser going forward. I really liked Firefox but it is useless for me now. Oh well.....

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Hello gilestra,

Firefox is useless for you because a button on YouTube doesn't work ......  ?

Before you switch to Chrome, maybe you'd like to take a look at this :

And also see my post in this thread :

Update :

November 29 - the "Show More" button works again (in Firefox and other browsers ..... )
