I had an extension that gave me access to Claude.ai. It was working quite well until this morning, when its CPU shot through the roof. I shut down its tab. I could not figure out how to restart it, and it's not in my extensions list. Was that deprecated? Is there still a direct interface to Claude.ai on Firefox? I pulled up About:Firefox, and it informs I must restart to update it. That was news to me. I could also (before restart), do successive Control-T presses to resurrect my Claude.ai. I will try that before restart. Could you tell me what I should look for in the Claude.ai tab, or elsewhere, if Control-T is successful? Thanks,
