You do not necessary need to use Tails while using Electrum. If you enable the proxy, Electrum will not synchronize if you are using Internet service provider network because it will only work with Tor even on mobile Electrum.
Once tor option is enabled on Electrum it will go thru tor directly without any other 3rd party tool? The green circle turned blue and it said 'synchronizing' and finally showing my balance again at the end of it all.
