Description

After finishing an upload of any file(s) with the build in flash uploader the Firefox error console shows warnings that typo3/backend.php tries to reference SWFUpload.instances.SWFUpload_n approx. every second, where n is the id of the used SWFupload instance.

This occurs for each and every instance of SWFUpload. Thus, these warnings are generated for each upload during one backend session which leads to several 10th to 100th of warning per second, depending on the frequency of uploads.

With growing numbers of thrown warnings this results in:
1) "Overwride existing files" gets ignored completely. Its never possible to overwride files in fileadmin from this point on until you logout, close the browser and start anew.

2) Usage of the flash uploader renders firefox error console entirely useless since it is impossible to examine "real" errors

enable flash uploader.
open firefox error console.
