Transient issue where the top of the page overlaps with the task bar (whatever it's called on the iPad) so the plus sign for new tab is under the iPad's battery indicator. Can't close tabs. Seems to happen when reopening the iPad, usually corrects after a few times of switching apps. It was happening when I was on the support page. I restarted FF, same result. Switched from this form to ipad settings to verify versions, came back and display was corrected. I haven't rebooted the iPad to correct the issue, if I have to do that more than once or twice I'll switch browsers. I never have one tab open, can't verify it happens then. I don't need a reply here, just figured if I was seeing it, something may need to corrected. I am willing, as time allows, to follow steps for troubleshooting if the issue recurs, if that's helpful. I can follow instructions reasonably well. Gani
