repost from there, here its probably more appropriate: https://support.mozilla.org/en-US/questions/1391582 In the meantime I figured out that sent tabs apparently only remain on the server for 60 days and that there is probably no log, even offline. But no definitive answer. And my feature request still remains for a history of sent tabs. Dear Mozilla Team, during the recent weeks I was away from my main PC and primarily used my iphone to browse the web. Every now and then I sent a link to the PC using Safari's share and the integrated send to function of Firefox for iOS. This usually worked really well, even when my PC was powered off. When I got back home and started my PC, sync would take forever, but was then interupted and all further tries to sync (hoping to get those tabs eventually) failed. My question is if there is a log file of all those links that are sent to different devices? I believe there has to be one given that Mozilla's servers are being used and tabs (usually) arrive on powered-off devices following a request to the server. If there is, please tell me how to access it/send it to me. If there is not, please take this as a feature request (a sent links history being gathered locally as part of the wider Firefox profile maybe and as a viewable list of all shared tabs for all devices so that tabs can still be sent to single devices but also accessed from others, similar to how tabs can be accessed from all synced devices). xxhen
