Requirements

We should disable the bubbles by default and add an option in download settings to allow users to switch the bubbles on/off.

Copy

Show download progress notifications
On/Off

@deeppandya as discussed on triage call - let's also update the "ask where to save files" copy to:

"Ask where to save files (if SD card is detected)"

@rmcfadden3 please let us know if the copy in the description works?

[rmcfadden3]

@timchilds — Since the word "bubbles" is probably not well understood, in this case I'd recommend something more explicit like:

• Show download progress notifications
• Show "Downloading file" progress notifications
• Show file-download progress notifications

[timchilds]

Thanks @rmcfadden3 👍 Makes sense - let's go with option 1.

@rmcfadden3 while discussing this with the team it was highlighted that the "ask when to save files" and "ask where to save files" copy does not really make sense to what the settings actually do.

It turns out "ask when to save files" is deprecated. So we'll just remove that as part of #25687.

"ask where to save files" is only relevant when the user has an SD card inserted in the device. It gives a choice then whether to download to internal storage or SD card. Could you please help with updated copy there? Something like:

"Ask where to save when an SD card is detected"

[rmcfadden3]

@timchilds — could we do a parenthetical here? So like"

"Ask where to save files (if SD card is detected)"
