First problem:

You need to have links with this pattern " Projets-Personnels " instead of "Projets Personnels". That's what we call a "slug"

Install doctrine extension sluggable so Doctrine auto create the slug for you.

https://symfony.com/doc/master/bundles/StofDoctrineExtensionsBundle/index.html

When you will have this doctrine extension installed you will create your link like this:

{% for item in categories %}

            <h2 class="lp-title"> {{ item.slug}} </h2>

      {% endfor %}

Second problem:

About your backspace bug on firefox on Ubuntu:

You need to enable the backspace if you use Firefoxe in Ubuntu.

Go to the bar url of your firefox browser and execute this adress about:config

Firefox will show an avertissement message it's normal. Click ok. Then you need to change the value for browser:backspace_action from 2 to 0

I have tested this solution on Firefox Ubuntu and it works fine.
