I think I've found a memory leak in plasmashell when Firefox is used to download plenty of individual files (~30) and has the plasma add-on installed and enabled, which causes every download complete event to show up as a plasma notification. I have recorded to videos showing the memory usage of plasmashell in the following scenario: download a bunch of images from a web page via DownThemAll - this allows to quickly download many files, hence triggering many download notifications (only when the plasma add-on is enabled) move to next page and download some more rinse and repeat a few times close firefox monitor memory usage by plasmashell during the test and at the end When the add-on is enabled, a lot of memory is retained. The video shows 4 or 500 MB, but previously it went as high as 7-800. When the add-on is disabled, memory usage increase by plasmashell is only a few MBs (although it might be worth checking if this gets properly released eventually...)
