What junk files are you referring to?

Trying to clean up these files that are labeled junk files. The computer is recognize them as junk. I can't tell you what they are because I really don't know. The computer tells me to delete them in order to speed up my computer. Any input would be helpful.. greg

Scan your computer or the browser and delete those things, or go to delete history, and delete everything, and if you want to, have all of the boxes with checks in them and delete those things as well.

Do you mean files in the temp folder or files in the Firefox profile (cache) folder or other files?

Which program tell you to remove such files or is this happening on internet sites?

Can you ask your question in other words? I'm confused by what you're asking.
