I found Salafi website’s views on Zoroastrianism.
Not an expert of religions.

(It’s important to mention it appears avesta, is the origin of rigveda of hindus, perhaps through meditation observers and their renewed understanding after meditation, hindusim might have evolved? )
He(islamqainfo) thinks that Zoroaster was not a real prophet but someone who passed on teaching of what he learnt from other religons (probably teaching of Bani Israel according to him). He thinks that ancient religion of Iran Magians and these teachings were mixed to form Zoroastrianism. However I disagree with Quranic evidence he presented. I think Quran is talking about the form of Zoroastrinism present during its time rather than of past. The salah part(majoosi namaz) could also makes sense if Zoroastrian origins are teachings(with some distortion) of bani israel.
What I understand from ghamidi sahab’s views is that. Earlier only few prophets for a qoum(Nation). Nations then migrated to different areas. If people had no revelation they might be judged based on fitra(based on shaoor of right and wrong we all posses). Then later Bani Israel were chosen(the chosen people) to guide people to the right path. Bani Israel then would be sent with lots and lots of prophets one after another (from amongst their tribe) to make sure they are guided.Then this responsibility of guiding people was given to bani ismail (Followers of Prophet muhamad).
Ghamidi sahab has already categorised religions as 1-Ilhamee mazahib from wahee 2-Sufiyana mazahib based on meditation and such experiences. He probably calls sufiyana mazahib as ijaad of people rather than guidance of Allah.
