"Media.cache_readahead_limit" and "media.cache_resume_threshold" don't have firefox default values what can cause bugs

[trimechee]

Hello, I often changed the values of media.cache_readahead_limit and media.cache_resume_threshold to full buffer video streaming and I managed to get full buffering but lately this trick doesn't work any more despite trying different values and it seems that it is the streaming websites which controls the quantity of the streaming buffering to save the bandwidth of the server, and therefore I remember when I was changing the values of media.cache_readahead_limit and media.cache_resume_threshold,i had problems playing twitter videos and I discovered that our beloved Mercury browser did not set the same values as Firefox concerning media.cache_readahead_limit and media.cache_resume_threshold, has this modification been studied and tested intentionally by Mr @Alex313031 or is this an error that can cause video playback bugs in some websites ?
