The discussion centers around user experiences with Firefox (FF) and Chrome, highlighting performance issues and security concerns. A long-time FF user reports sluggishness in the application, leading to a switch to Chrome, which is praised for its speed and smoothness, especially with the recent release of Chrome 10b. However, there are concerns regarding Chrome's slower response to security flaws compared to Mozilla and Apple, with some users noting that while critical issues are addressed promptly, medium-level bugs can linger. Another participant mentions that FF slowdowns are often due to extensions, suggesting that clean reinstalls can restore speed. There is also a discussion about the user-friendliness of Chrome, particularly regarding tab management, where Chrome lacks options available in other browsers to control how new tabs open. Overall, the conversation reflects a mix of satisfaction with Chrome's performance and ongoing concerns about its security and usability compared to Firefox.
