Is it OK to delete cache files in profile folder. I have more than 20 in there . Can I just keep the latest?

more options

My default Profile folder at 8xvafniu.default currently contains Cache folders numbered up to 23, an OfflineCache folder and startupCache folders numbered up to 6. Can I delete these leaving me only with the latest numbered Cache folder and startupCache folders. The OfflineCache folder I will keep, of course, along with the 2 urlclassifier files. Thanks for your help.

No, you need to keep all cache folders. Firefox 4+ versions use a different cache structure and spread to files over sub folders to make it possible to store more files in the cache.
