Right click copying text from websites in Firefox causes KDE panel to temporarily freeze. Auto selection copy to middle click paste seams not to cause this issue. Sometimes it's frozen for a couple of minutes. It's CPU usage isn't high during this time frame. During this time the clock isn't updating it's seconds, and clicking on/mousing over items in the panel doesn't do anything. Windows are still fully functional during this time, and I can move windows around just fine. It seams worse the more I copy text? Debian Stable 9.x 64bit Firefox-ESR 52.7.3 Parcellite 1.1.9 Klipper 5.8.6, 2048 entries, (2 icons somehow, and they have different style left/right click menus, one says "Configure - Plasma", the other "Configure - Klipper", ...) Plasma [If this isn't in the right area feel free to move it.]
Was it a long text that you copied? Can you get a backtrace of when plasma freezes?
With short text around a word or so it freezes for around a second, but for longer text around a average size paragraph it can freezes around a minute or more. Right now I can see that it has been frozen for close to 5 minutes, and it just now came back to working like nothing happened. No crash dialog box or anything. During the freeze the panel doesn't do anything. With just the text prior to this sentence text copied in at 14:05:44 the panel finally unfroze at 14:08:16, for a total of 2 minutes and 32 seconds frozen.
"Can you get a backtrace of when plasma freezes?" How can I do this? It's not 'crashing', so the automatic backtrace box doesn't show up.
Just tried running Firefox-esr with '-safe-mode', and this problem doesn't seam to be occurring now, so maybe it's a browser plug-in(s)? It' seams weird that a firefox plug-in might cause plasma panel to freeze when copying text. What plug-in(s) would cause the KDE panel to freeze when copying? Ideally even bad written browser plug-ins shouldn't freeze the kde panel.
On console run gdb plasmashell then type r (run), make it freeze and when it does Ctrl+C and type thread apply all bt and paste the output here. This should give us a clue where it freezes, I suspect somewhere in QMimeData. Make sure to install debug packages for at least Plasma (framework, worksapce, desktop). Thanks!

Thanks for the report. I've been using Firefox on KDE almost exclusively and haven't had this issue. Can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved. I've set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved" when you respond, thanks.
I haven't noticed this in a very time, and practically forgot about it. Just tried copying text in Firefox again, and didn't notice this bug happening. So I'm changing it from NEEDSINFO to RESOLVED.
