I am using Firefox on my iPhone 7 with iOS 14.3. Since some months I am experiencing when loading Firefox, it hangs for a few seconds to load my 'Top Sites' icons. Quite often, for around 10 - 15 seconds Firefox halts after which it crashes and I am back to the iOS Home Screen. This does not occur all the time. Sometimes Firefox works normally-, sometimes not. It is not clear to me how I can reproduce this issue but I suspect it could have something to do with limited resources? Low RAM? I have tried completely removing and re-installing the app. It also did not solve the issue. Thanks in advance for your help, Regards,
