I have signed into firefox on my Iphone and it will only seem to refresh the synced tabs page (that I have open on my desktop) when I force it to sync from my desktop. Otherwise it doesn't seem to want to resync. I have checked the notifications to make sure it can notify me if it needs persmissions and it is already on. I can't find the "sync schedule" anywhere that I saw mentioned in another answer. I tried going through the about:config to reduce the 600,000 ms sync schedule but it just resets back to 600,000ms. Not that waiting the 10min means it will actually refresh.. Help please! :(
