Why does SeaMonkey keep setting media.autoplay.enabled to true whenever

which recommended setting that to false. It does not seem to do the job
anyway, but I have modified an extension to toggle that setting and I
always see that enabled with starting up.
Is there some other setting which would give more control over the
playing of HTML5 items? Flashblock works fine for that with Firefox, but
that version will not install in SeaMonkey.
If you have the PrefBar extension, I created a button to toggle
media.autoplay.enabled between True and False. Let me know if you want
it.
If you don't want to bother with PrefBar, you have two choices, both of
which simply disable HTML5 media displays:
Choice #1 -- Set user.js
1. Locate your profile folder. If you do not know where it is, select
[Help > Troubleshooting Information] on the SeaMonkey menu bar; on the
Troubleshooting Information window, select the Show Folder button to the
right of the label Profile Folder.
2. If you do not have a user.js file, create an empty file with that
name.
3. Open user.js in a plain-text editor.
4. Insert the following into user.js:
user_pref("media.autoplay.enabled", false);
// blocks HTML5 media
The semi-colon (;) at the end of the first line is required. The double
slash (//) at the start of the second line indicates that line is a
comment, to remind you why you did this.
5. Save the edited user.js back into the profile folder.
6. Terminate all instances of SeaMonkey. Restart SeaMonkey.
Choice #2 -- Modify prefs.js:
NOTE WELL: It is generally a bad idea to modify prefs.js with a text
editor.
1. In the SeaMonkey window address area (URI bar), type about:config
and hit Enter.
2. In the Search area, type media.autoplay.enabled.
3. On the display below the Search are, double-click on
media.autoplay.enabled to toggle it to "false".
While this is more simple than Choice #1, file prefs.js does not allow
any user comments.
I already have media.autoplay.enabled set to false. I changed the
toggling extension to toggle media.webm.enabled instead. Neither seems
to make any difference to whether HTML5 will work or not. It works
anyway. As long as the HTML5 video has a play button, that is fine, but
I am anticipating a time when some of those items will not have any play
button and will start up automatically, and I do not want that.
What other settings are there that have an impact on the startup of HTML5?
