Solve the problem that ff Firefox cannot watch videos

1. Open ff Firefox in our computer

2,

Then, in the window, click the third horizontal button in the upper right corner, as shown in the figure.

3. Then, in the small window, click the Add component button, as shown in the following figure.

4. Find the plug-in.

5. Then, we only need to change "always activated" to "never activated", as shown below.

6. That's OK. Now this plug-in is disabled. You can open your browser to watch the video. It's easy.

Okay. Of course, this will be available only when swf is enabled in ff browser. A prompt will pop up when we refresh the interface, and we can click allow.
