Hi

That is currently not available in Firefox for Android, but it is something that may be considered in a future update. Please appreciate that for many people opening large numbers of bookmarks may causing crippling performance issues as they may not have a top of the range device

Thanks for the response. Opening too many tabs at once could definitely cause a performance issue, but it would be nice to have the option for a reasonable number of tabs. Maybe a confirmation dialog could pop up if the number is deemed excessive.

Thank you for the additional feedback, hopefully this feature can be included in a future update.
