Is Speed Booster Toolkit for ChatGPT safe?

Low risk

Speed Booster for ChatGPT changes ChatGPT page rendering to keep long conversations responsive.

The extension runs on chat.openai.com and chatgpt.com, counts conversation turns, and renders a smaller set of messages so long chats use less browser memory. It stores settings, usage quota, and license status locally; if a user activates Pro, it connects to Freemius to validate the license key.
