Wordpress wont work on firefox, Cant access database

Okay so anytime i use firefox to access my site at johnwolfe.ca i get …

…you will notic in the address bar it says httpS://www.johnwolfe.ca
however the thing is when I access with chrome and get into my wordpress admin the url is quite clearly saved as http://johnwolfe.ca. just typing “johnwolfe.ca” in any other browser mobile included seems to be working fine. Wasnt like this until i editted my wordpress address and site address in general settings off the dashboard menu (picture below)

When I try logging into my wp-admin in firefox I get this screen…

so i login to 000webhost to manage my database and USING ANY BROWSER i get an error when I try to access “manage DB” shown below…

I made this site to submit my set to a festival and give them some information but competition is tight and i need to be on point i cant be hoping they dont use firefox… can anyone help me get my site showing on firefox please?

Regarding the manage DB issue try this

Sometimes your local Internet Service Provider may use outdated DNS servers, or your computer might be configured to use set ones also which might not be as up to date as the ones I’ll provide below.

Using different DNS servers should not impact your performance, if anything it will make loading sites faster and any changes to other peoples websites should reflect faster as well.

First you’ll want to navigate to your start menu, control panel then network connections.

Once open you’ll want to right click on the connection your computer uses to connect to the Internet be it ethernet wired connection or a wireless connection to your router and select properties.

Once the properties menu appears you’ll want to select Internet Protocol Version 4 (TCP/IPV4) then select properties

Once now on the last screen you’ll want to type in 8.8.8.8 as the first one and 8.8.4.4 as your secondary DNS server.

Now close and save all changes.

Now you’ll want to do the following - find Command Prompt within your start menu else hit start, run, cmd.exe and then open it.

Once open just type ipconfig /flushdns

I hope this aids somewhat.
