Avoid Duplicate Downloads

Annoyed by the browser just download files with the same name by just appending "(1)" "(2)" to the filename without your confirmation? Chrome automatically appends (1) to the end of the filename if there's another file with the same name in the download folder. If you are tired of having a lot of duplicates files in your download folder, look no further. With this extension, you'll be prompted with "save as" dialog for you to choose either rename the downloading file or overwrite the existing file. No more filename(1).pdf in your Downloads folder. This is also an open source project: https://github.com/hlwjia/avoid-duplicate-downloads-chrome-ext
