I-Firefox iOS Isithangami Sokwesekwa

I had about 500 tabs on FF on my iphone open. The browser crashed and now all of those seem to be gone. "Recently Closed" is empty. Starting the browser just opens an empty page. I had sync turned one but oh magic the synced tabs pretty much immediately diappeared from the other devices as well. Any ideas how I might be able to recover those tabs? Could they still be saved somewhere on the iphone or in the cloud?

I had many tabs open in firefox on my iphone, which were unique and not open in firefox on my laptop. Inhad kept them there for a while because theyvwere important. I happened to tap on 'pick up tab' from my laptop in order to work on something from my phone for the forst time. This looks like a new feature that I didnt notice before. It opened that tab but immediately closed all of those tabs I had kept opened. It also deleted and overwrote all of my iphone history, so that everything exactly matches my laptop. If I go in my iphone's firefox history it does not show those old tabs under recently closed tabs! I can't find those anywhere. Help! Had I known it would do this I would have made sure to save the tabs and history somehow! How can I get my iphone tabs and history back?? Thank you
