I was flying to observe a friend's home after a wildfire.  I was using my EFB for navigation and was very aware of the presence of multiple TFRs.  According to my visual landmarks and the perimeter of the TFR according my EFB; I was clearly outside of the TFR perimeter as it paralleled the coast and was slightly inland.  I was contacted by another pilot that he thought I may have violated a TFR. I assured him I was very careful using my EFB and very identifiable landmarks.  His comment was the the TFR had expanded and encompassed my course of flight.At XM:00 pm the evening of my flight when I opened my EFB; the TFR had indeed expanded.  Even though the active time was listed as XA:00; my EFB updated nearly 12 hours later.I am Respectful of the firefighting TFRs and am grateful that the fire was nearly out and there were no fire fighting aircraft in the vicinity. I will follow up with my EFB vendor to report this incident.
GA pilot reported a possible entry into a fire related TFR which was not depicted in his EFB pre-flight; but was noted post flight as the EFB updated.
