Firefox local storage and cache questions

I found the location at last, It seems the new google chrome has changed the location for Flash temporary files, instead of using the old location for cache files

...AppData\Local\Google\Chrome\User Data\Default\Cache

it is using the below new location:

...\AppData\Local\Google\Chrome\User Data\Default\Pepper Data\Shockwave Flash

However I am not sure if it is keeping all files there or only big files (say 100Mbs or more).

Thanks for help!

Update March 2018

Now a days, in most cases, youtube doesn't buffer complete video at once, it buffers in chunks as you watch. Pause the video, the buffering will also be paused.

Also, youtube, uses two WebM streams, one for video and other for audio. These both webM streams will be in cache as separate files. So we have to combine both to watch a video, or play both to watch the video. (But if you fallback to old browser which doesn't support WebM, youtube will fallback to MP4)

Again, not sure if browser is keeping the old chunks of the these files or not, but even if it is keeping, its very hard to find all those right chunks and combine them.

However, if you still interested, chrome uses below cache locations:

C:/Users/.../AppData\Local\Google\Chrome\User Data\Default\Cache C:/Users/.../AppData\Local\Google\Chrome\User Data\Default\Media Cache\

The video will be there in the cache only as long as you are seeing it in the browser, after which it is deleted automatically. I would recommend using plugins provided by modern browsers if you want to download the video.
