InternalError allocation size overflow nodeCreated/widget.serializeValue@http://127.0.0.1:8188/

Hello together,

I´m new to ComfyUI and I love it.

All went perfectly.
But today after I installed the custom node
_"[sdxl-recommended-res-calc](https://github.com/marhensa/sdxl-recommended-res-calc/tree/main)_ "
I´m not able to use the batch funktion. Only one Queue Prompt starts.
The window of pending que is empty.
In the debug I saw this entry:
`InternalError
allocation size overflow
nodeCreated/widget.serializeValue@http://127.0.0.1:8188/extensions/core/dynamicPrompts.js:36:72
graphToPrompt@http://127.0.0.1:8188/scripts/app.js:1639:66
`

I have uninstalled the node, rebooted completly, but the batch won´t do anything.
One simple prompt starts. Any suggestions?

Greeetings
Michael

P.S. sorry for my bad english, English ist not my native language.

EDIT:
It seems to bee an issue with the FireFox. I tested it with MS Edge an it works.......
