Pencu Ndimabu Firefox bu Android

while performing a download, "com.android.phone has stopped" apears, the signal strenght indicator in the upper right restarts(disappears, reappears with the 4G mark, the mark disappears and the indicator works after), after that the phone service and the phone app work normally. the download finishes normally.

using motorola e7 plus, android 10

tried restarting the phone, deleting cash and data of phone app, deleting cash of firefox

tried downloading using google chrome, all work normally.

it is possible that the issue started happening after I updated firefox but It's possible that it was happening before too.

Is it by design Speech Synth is installed in the background on Android 8? I don't have it listed in my logs that I installed, unrequested install. Also Firefox 116.0.3 now calls for Speech Synth to be installed. Is this normal?
