I have created a Filter called Block List. I can't find a way back to it or to add addresses I want blocked. The instructions in the help site don't seem to have any relativity to the software. For instance the filter I created can be opened by going to the tools menu and selecting Message filters, but there is no entry for Message filters. See: https://support.mozilla.en-US/kb/blocking-sender. The instructions for adding additional addresses to the list are confusing to say the least. The problem could easily be me not understanding what's going on. Thanks
