SUMMARY Opening a larger file(>1MB) in firefox causes plasma to offer you to open that file although it is already opened. Doesn't happen with small files i.e. 200KB STEPS TO REPRODUCE 1.Open a file >1MB in firefox(i.e. pdf) OBSERVED RESULT Plasma offers you to open the opened file EXPECTED RESULT Plasma doesn't do anything SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20210208 KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2 Kernel Version: 5.10.12-1-default OS Type: 64-bit ADDITIONAL INFORMATION On a faster internet you might need to open a larger file. It seems to be bind by time i.e. if it's not an instant open, plasma will shot the dialog.
Where and when does it offer that? You mean you get a download notification when you just open a PDF on a website and when it finishes, Firefox opens the PDF, but the notification offers an "Open" button?
Above the notification tray. When a file is downloaded. Yes, but only on larger files. Small files don't proc a notification.
It only shows a notification for jobs that take longer than 500ms, yes
