I have been using Firefox for years.

I'd trust open source stuff on github more then closed source binaries from Microsoft.

No longer connected to the Sony downward spiral

OpenAI is now rolling out Lockdown Mode to more ChatGPT users by Pradeep Viswanathan Back in February, OpenAI first announced Lockdown Mode for users who want the most comprehensive protection from potential attacks. At the time of the announcement, the company mentioned that this feature was available to a small set of highly security-conscious users, including executives or security teams at leading organizations. Today, OpenAI announced that Lockdown Mode is now rolling out to all personal ChatGPT accounts, including Free, Go, Plus, and Pro, and also self-serve ChatGPT Business accounts. Users can enable the feature from ChatGPT Settings > Security when it is available for their account. When Lockdown Mode is enabled, ChatGPT limits or disables several features that connect to the web or external services. These include live web browsing, Deep Research, Agent Mode, and more. Here is the complete list of services that will be disabled in Lockdown Mode: Live web browsing: Web browsing is limited to accessing only cached content. Search results may be limited, unavailable, or stale. Image support: ChatGPT may not display images in regular responses or retrieve images from the web. Users can still upload image files, and image generation remains available where it is otherwise available. Deep research: Deep research is disabled. Agent mode: Agent mode is disabled. Canvas networking: Users cannot approve Canvas-generated code to access the network. File downloads: ChatGPT cannot download files for data analysis. ChatGPT can still operate on your manually uploaded files. It is important to note that Lockdown Mode does not completely block prompt injections from appearing in content that ChatGPT processes. For example, a malicious instruction could still be present in an uploaded file or cached web content. However, the mode is designed to reduce the ways such an attack could send sensitive information outside the conversation. Along with Lockdown Mode, OpenAI today also announced that the Active sessions feature is now available across ChatGPT accounts and workspace types. This feature allows users to review where their account is signed in across devices and end sessions if required. A session will have the following information displayed: Device or browser information. First-party app context, such as ChatGPT, Codex, or API Platform. Approximate location. Sign-in date and time. Whether the device is a trusted device. Whether it is your current session. OpenAI highlighted that the Active sessions feature will not be available for accounts linked to an organization’s single sign-on setup, including SAML or OIDC.
