A stopgap solution until Derpibooru implements the feature natively.
 
Shows a toggleable icon on the top left of all webms that contains an audio track.  
On the image page the icon is hidden until you hover over the image.

Nice script!  
Is it possible to make a toggle icon at the webm’s page a bit larger?

StSyaN  
Of course! How much larger do you want it?

I increase the font-size from 2em to 2.5em on the image page. you can test it out by adding font-size: 2.5em; to the CSS selector #image_target .volume-toggle-button.

@Marker  
As for me about of 4-5em is okay

StSyaN  
4 is a bit too prominent for me, how about we settle for 3.5?

@Marker  
How about an option for it? :D  
Anyway, as you wish, I may edit userscipt or create a userstyle for it

StSyaN  
You mean stick it in that nicely commented section at the top? Sure I guess, but you’d ended up editing the source anyway, as those configs doesn’t carry over across script updates.

Yeah

I know, the only solution is localStorage. But if nothing will change on derpibooru, there should not be many script updates…

Script updated to 1.0.15

Oh you’d be surprised how many bugs I often find in my code after I publish it.

@Marker  
Same thing that’s why I often serve ‘night’ and ‘stable’ version separately

Thanks for the script. Very helpful :3

So, apparently on Firefox the webm thumbnails aren’t muted when they were inserted into the page, leading to a terrible cacophony on the gallery when displaying webms. Version 1.0.16 fixes this bug.
 
Also, I’ve been trying to solve the problem of Chrome occasionally seizing up when trying to load/play multiple webms simultaneously (48 in my case), this will affect you if you have SERVE_WEBM_THUMB or PAUSE_IN_BACKGROUND enabled. If you’re one of those severely affected, -try the experimental version that I’m working on, it’s still terribly buggy and _{leaks memory on rare occasions} but hopefully makes the problem occur less frequently. It also contains enough logging to deforest the Amazon. Edit: Nevermind don’t use the script the memory leak is bad.
