Firefox Version 63.0 (64-bit) Home build PC, 480GB SSD, 2 x 2TB HD's, 8GB Ram.

I have had problems with streaming Channel 4 TV UK for many years. I could only get it to work on Windows. Recently I have Dumped Window 10 - so slow - updates take all day. I now am using Ubuntu 18.04 LTS (using Linux since 2009)

Channel 4 say they Do Not support Linux ?

I have tried to install Adobe Flash Player, but does not seam to work or download. On Ch 4 web page I pressed Allow, but say that I should install Flash Player !

Please could anyone advice me what I can do, or what I have done wrong.

Regards, Richard.

Make sure you are not blocking content.

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?

One issue that seems more common lately is Firefox's Tracking Protection feature. When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature: Tracking Protection {web link}

Please explain the problem in detail. What happens? What is the exact error messages?

Hello Rich_42,

You switched from Windows to Linux - Channel 4 does not support Linux (which you already mentioned ..... ) :

Using more than one program to do the same job could lead to problems.

Have you tried Firefox Safe Mode as I asked?

Sorry late getting back with my answers, not been well. over 75yrs old.

I have deleted uBlock. Started Firefox from Terminal. Tried to stream Channel 4 - Said I need Adobe Flashing installing. Tried to do this - selected Ubuntu Flash - New window said - This link needs to be opened with an application. Send to: Then there is 2 Apt URL (in Bold) Choose other Application (Choose) There is a cancel Button A Open link button (Which is Greyed OUT) and does NOT work ?

Still the same as before - I can't install Flash or stream Ch4 ?

What is : <Shift> (Mac=Options) key, and then starting Firefox.

As to the 'Allow,' That is Firefox stopping the page from reloading.

Type about:preferences#advanced<enter> in the address bar. Under Advanced, select General Turn off Warn me when websites try to redirect or reload the page.

In Firefox 56+ the "Warn me when websites try to redirect or reload the page" setting can no longer be found in Options/Preferences. You can modify this pref on the about:config page to enable or disable this feature


True Instead of refreshing a page automatically when [meta http-equiv="refresh"] is present (or Refresh HTTP headers), display a browser message indicating the refresh and allow the user to follow it manually.

False Allow automatic page refreshes
