trouble loggin into github and making searches in local machine

[simin75simin]

so i've made it running on ubuntu 18.04 with the following steps:

install npm, bower, grunt, fix some issues. might wanna look at:
  https://stackoverflow.com/questions/12369390/bower-command-not-found
  https://stackoverflow.com/questions/55921442/how-to-fix-referenceerror-primordials-is-not-defined-in-node-js
install ruby-full using apt, sudo then gem install compass
  note compass is not mongodb's compass!
at this point shall be running grunt server, yet another error occurs, might wanna look at:
  https://stackoverflow.com/questions/55763428/react-native-error-enospc-system-limit-for-number-of-file-watchers-reached
after all those should see page same as this one:
  http://www.yasiv.com/github/#/
at this point should be able to connect to own github account otherwise check internet restrictions

yet after an initial successful run, i wasn't able to run any searches or log into github. i was able to get redirected to github's login page, but it doesn't show my account after i successfully log in.

i am using a socks5 proxy and firefox. so that might be why. but still i wonder if there's a way to work with the proxy server?

thanks in advance.
