Hi In the absence of network connectivity, submitting a search or entering a URL in the universal bar fails to detect the network issue. Moreover, the content of the universal bar is lost (forcing the user to type again, which can be very frustrating for a long URL) How to reproduce: - open firefox iOS - switch your phone to airplane mode and deactivate wifi - open a new tab and try accessing any webpage (eg mozilla.org, or type something to be searched) - observe how the content of the bar is instantly lost and a blank page is displayed. What should be expected: - the universal bar should still contain whatever was typed (or the URL of the search engine) - the body of page should display the usual "The internet connection appears to be offline" message. PS: this apparently only happens in newly created tabs, not with existing ones.
