Requesting changes to correct the data below. I confirmed with Chrome people that my interpretation of the versioning is accurate (140, not 145).

There is no space for a suggestion, but please also add splitViewId to the properties of the tabs.onUpdated event, this is Firefox 149 desktop only.

"version_added": "149"
},
"firefox_android": {
"version_added": false

Note: unlike the other parts I am leaving this as firefox_android.version_added = false because the tabs.onUpdated event does not fire with splitViewId in practice.
