Problem While watching online videos

Hi,

Yesterday i noticed that while I'm watching online videos like youtube and so on my C: diskspace is shrinking. While I was watching yesterday 2 hours long E3 Sony pressconference diskspace reduced 5-6 GB. Why this is happening ? Is it normal ? I have 4 GB of RAM on my PC. When i close Firefox diskspace returns like it was before watching. When I looked in Firefox it says that is using only 11,1MB cache. Anybody can help ???

Edit:

I just noticed that this folder suddenly became 10GB in size:




After i closed Firefox almost everything from that folder dissapeared

Maybe Firefox is saving the videos in your temporary files folder.
Have you tried clearing your temporary files folder whilst Firefox is open?

You could try deleting these files with Disk Cleanup - Delete Temporary Files with Disk Cleanup

Hope I helped.

This is not the same folder when you open start and write %temp%

Yes, you could always open run, and type %temp% and then delete all the contents of that folder.

Yes, but thats what i mean its not this folder %temp%

%temp%
AppData-->Local-->Temp

Folder who shrinks all space is Temp

-->Local disk ( C: )-->Windows-->Temp

Ah, ok I see.

Try clearing the cache of Firefox when running, then check disk space.

Clear Firefox Cache

Clear Firefox Cache

Thats the point Firefox was showing that it was using only 11,2MB cache.

When i close Firefox i get diskpace back so its kind of no point to run CCleaner.
