Have you noticed how some posts on news aggregators have audio gain at 100%? You browse one video with mumblers so you turn up your sound a bit then hit the next one that's at 100% gain and it blows out your eardrums. With the rise of TikTok this is happening much more frequently.
The fix for this is sound compression. It lower sounds above a certain level. There are extensions that do this but none of them work well because they are not allowed to change cross-domain audio sources. This affects many sites since pulling video content from other sources is very ubiquitous now.
