"Hi there! I've been experiencing some difficulties with the Mozilla Firefox mobile browser on my Android device. Whenever I try to open certain websites, the browser crashes unexpectedly. I've tried clearing the cache and reinstalling the app, but the issue persists. Could you please provide some guidance on how to troubleshoot this issue or any possible fixes? Thanks in advance for your help!"
