Description: Calc freezes within 3-4 minutes of routine use such as copy/paste of cells, saving the file. This apparently only happens when browser Firefox is also open. Firefox had an update several days ago (~1/8/21), and Libre Office's Calc now quickly freezes with typical use. Once Calc freezes, I am not able to close it with Task Manager nor with with command line commands; I must re-boot to close Calc, losing some work. This has now occurred ~10 times. I have isolated the occurrence to only happen when Firefox 84.0.2 is open. My Operating System: Windows 8.1 Libre Office versions which freeze(tested on): 7.03, 7.04, 6.47. Actual Results: Open Firefox 84.0.2 on a a Windows 8.1 PC, then open Calc, do some routine copy/pastes of cells, rows, then Save the file -repeat the actions 7-10 times. Expected Results: Calc freezes ("Not Responding"), with application display greyed-out, and no longer responds. Calc will not respond to forced closure when using Task Manager, nor from Microsoft Windows "End Process" dialogue box, which will appear when repeatedly trying to "X" out of Calc. Reproducible: Always User Profile Reset: No Additional Info: Calc should operate without freezing. (Sometimes Calc takes 10-20 seconds to save.)
This occurs even when using Libre Office "Safe Mode", but just takes longer to experience.
I have been able to experience Calc freezing after just a few copy/paste/save operations without Firefox also running, but with the Livemail e-mail application running. Calc freezes with either Firefox or Livemail running.
Thank you for reporting the bug. Calc does not freeze after performing copy/paste of cells, when browser firefox 84.0.2 is also open. I can not reproduce the bug in Version: 7.0.3.1 (x64) Build ID: d7547858d014d4cf69878db179d326fc3483e082 CPU threads: 4; OS: Windows 6.3 Build 9600; UI render: Skia/Raster; VCL: win Locale: en-US (en_US); UI: en-US Calc: CL Version: 7.2.0.0.alpha0+ (x64) Build ID: 761a672d62df1891b9f4f367a499b220ab2b33fa CPU threads: 4; OS: Windows 6.3 Build 9600; UI render: Skia/Raster; VCL: win Locale: en-US (en_US); UI: en-US Calc: CL
Apparently I had a corrupted system file(s) which coincided with a Firefox update. Using various Windows check & repair commands of CHKDSK, DISM, sfc /scannow, one or more damaged files was restored to where the Calc no longer freezes with Firefox running or being connected by WiFi.
