Last week I updated to iOS 15.0. For the first few days my Firefox app worked just fine, however over the last 24-36 hours or so it has been crashing with increasing frequency. Earlier today, after a crash, I clicked 'okay' to restore the tabs and nothing came back. They're all gone. Short of sifting through my history and trying to identify the tabs that were open on my phone, is there any way I can restore them? Thanks for any help you can provide.
