The incidents all took place in Norwich between March and July 2025 and CCTV footage captured the moments improvised incendiary devices were set alight.
According to the BBC, it is believed that she set the devices alight using sparklers.
Following a 12-day trial at Woolwich Crown Court in London, Goddard was found guilty of six counts of criminal damage and one count of making an explosive substance.

She was not found guilty of attempting to cause explosions or of offences connected to an attack on the Tacolneston transmitting station in south Norfolk.
During the five-month series of attacks, between March and July 2025, Goddard set off homemade devices filled with a pyrotechnic chemical compound called thermite, which caused damage to buildings.

The attacks caused thousands of pounds worth of damage, the court heard.
Goddard was arrested in October, at which point the attacks using thermite stopped in the Norwich area.
Police found Goddard had ordered several kilograms of substances to her home used to make thermite, a pyrotechnic that creates intense, extremely hot chemical reactions.

She also left homemade posters at the scenes with slogans such as “Stop Bombing Gaza” and calling the BBC “cowards” over its coverage of the conflict.
The posters became key in identifying her as a suspect after her fingerprints were found on them.
CCTV footage of the incidents also captured her wearing clothing, including a camouflage jacket and a black hat, which were found at her home in Sarah Williman Close, Norwich.
Goddard is due to be sentenced at Woolwich Crown Court on 16 October.
