I don't know about the technicalities or how they are to hack the software with all the mnemonics attached. When I saw the flash message early in the day, I upgraded immediately and my wallet is already password protected. I hope everything is safe and everyone is able to stop panicking especially those who are not on the forum to read the warning and the progress that has been made. Electrum is one wallet that to a large extent has been able to create a niche for itself and I think vulnerability at this time will tarnish the over the years reputation.
You are right.
1. I am protected by a decent wallet password
2. I only use mozilla browser
3. I have upgraded to the v3.0.4
Nevertheless, this vulnerability is getting into my head too much.
Its image has already been tarnished with me and it may be the same with other people and is likely to last for years.
I love electrum though for its light-weight feature and other features as well.
Maybe i should give electrum a second chance
