DropDown menu automation re-playing fine

{
“Command”: “click”,
“Target”: “xpath=//[@id=“aD3D2951D-A035-46B6-BAB9-431FFE821E65–98”]/span",
“Value”: “”,
“Targets”: [
"xpath=//
[@id=“aD3D2951D-A035-46B6-BAB9-431FFE821E65–98”]/span”,
“xpath=//material-select-item[2]/span”,
“css=#aD3D2951D-A035-46B6-BAB9-431FFE821E65–98 > span”
]
},
{
“Command”: “click”,
“Target”: “xpath=//[@id=“default-acx-overlay-container”]/div[6]/material-dialog/focus-trap/div[2]/div/div[2]/div/collection-editor/material-picker/div/header/div/material-checkbox/div/material-ripple",
“Value”: “”,
“Targets”: [
"xpath=//
[@id=“default-acx-overlay-container”]/div[6]/material-dialog/focus-trap/div[2]/div/div[2]/div/collection-editor/material-picker/div/header/div/material-checkbox/div/material-ripple”,
“xpath=//material-checkbox/div/material-ripple”,
“css=#default-acx-overlay-container > div.pane._ngcontent-qtv-76.modal.visible > material-dialog > focus-trap > div:nth-child(2) > div > div.main._ngcontent-qtv-77.with-scroll-strokes > div > collection-editor > material-picker > div.picker._ngcontent-qtv-79 > header > div > material-checkbox > div.icon-container._ngcontent-qtv-85 > material-ripple”
]
}

this is the auto json generated with record button on firefox. when i replay this macro it does not work on drop-down menu and through error right on the next step. e.g (
timeout reached when looking for element ‘xpath=//*[@id=“default-acx-overlay-container”]/div[6]/material-dialog/focus-trap/div[2]/div/div[2]/div/collection-editor/material-picker/div/header/div/material-checkbox/div/material-ripple’ )

while the same macro code is working fine on chrome but gives me error on firefox.

What UI.Vision RPA are you using in Firefox? V5.9.3 or V5.8.9?
