I just lost several hundred tabs on Firefox mobile right after it updated itself. The most recent tabs show only ten of those tabs, which were all opened and closed today and aren't part of what I need to restore.

How do I get my tabs back? I've seen no 'restore previous session' option. My laptop only shows the few I have open now. What do I do to restore them?

Hi, when I try to upload a file such as my resume to a job board it won't open my file location on my device. When I click on the websites upload button it doesn't do anything. I have tried on many websites with the same outcome. When I go to the same websites using Chrome it works.
