I don't understand your "11 years" comment, but anyway if you're asking, "Can I rely exclusively on iFly to keep me safe from busting TFRs," I think the answer is "No," and it's not iFly's fault. iFly will show you what the FAA is broadcasting in the ADSB messages, but if the FAA doesn't broadcast it, you won't see it.
In my area, I have never noticed a TFR missing on iFly that I was aware of. However, others (maybe it was you?) have said that the fire-related TFRs in the Pacific Northwest are not reliably appearing.
Bottom line: YMMV. Get a pre-flight briefing and talk to ATC in the air if you want to be covered.
