[26] In October 2019, it was reported that leaders of the IFP, along with other groups were assisting in the organisation of protests in Oughterard Galway against the founding a direct provision centre.

[32] In July 2020, IFP along with Renua and The National Party, organised and participated in a protest against the appointment of Roderic O'Gorman as Children's Minister for the new Government.

The groups involved called the protest after a photo surfaced of O'Gorman alongside gay rights activist Peter Tatchell, who has been forced to defend comments he made in 1997 in which he spoke about sex between adults and children.

John Connors later publicly apologised for his attendance to which O'Gorman accepted, clarifying that the photo in question was the only time he had met Tatchell, and that he was previously unaware of his controversial comments.

[61] During the COVID-19 pandemic in 2020, the Irish Freedom Party organised and had a number of representatives speak at multiple large anti-vaccination and anti-lockdown rallies.

[62][63] One rally, held outside the Dublin Custom House in August at which Ben Gilroy and Dolores Cahill spoke, was attended by "hundreds" and reported to have passed off mostly peacefully, despite some instances of violence between attendees and counter protestors, after which four were arrested.

[35][64][65] Cahill, who was then a non-lecturing professor of translational medicine at University College Dublin,[2][66] also spoke at an anti-vaccination and anti-lockdown event in London,[67] which later lead to a warrant for her arrest in the UK.

[68] In a video, published in May 2020 but later removed by YouTube, she claimed that COVID-19 could be cured or curtailed by "eating healthily and taking vitamins C and D",[69][70] that there was "no need for a vaccine" because people who recover have life-long immunity, and advocated using hydroxychloroquine and ivermectin as COVID-19 treatments.

[72] In early March 2019, a number of regional newspapers reported that a party-member named 'Mairead Donovan' was listed on the organisation's website, and would be running as a candidate for local elections for Kerry County Council.

[74] In responding to these reports, party spokesperson Hermann Kelly acknowledged the mistake and fault in allowing the placeholder profile and stock imagery to be published on the website,[74] and clarified that the group was not planning to run any candidates in local elections.

It was alleged that an IFP supporter tried to tear an LGBT flag from the hands of a counter-protestor and shouted homophobic slurs and made death threats.

Malsack-Winkemann spoke at an Irish Freedom Party event in August 2020, after which Hermann Kelly entertained her and her daughter by showing them the Celtic high crosses at Monasterboice.
