Hi! This seems to be related to whatever issue was happening on Firefox when "Fixed an issue where data consumption from service workers may unexpectedly halt (Bug 1941210)." was done and consequently fixed it. My issue in particular has to do with trying to import yomitan dictionaries on mobile and it aborts midway through and says there was an JSON.parse error. Looking at it on GitHub, there was an issue like this with yomitan and Firefox and seemed to have been fixed by Firefox (on desktop?) but this continues to happen. The yomitan issue on GitHub was "Importing dictionaries stuck on validation step #1765" and wasn't a problem on yomitan's end but specifically Firefox. I have tried importing with other browsers on mobile and the only issue I've run into has been the size of files, not the error Firefox shows. Thank you for any assistance.
