Zoom Page WE knows how to make good software. But they do NOT know how to provide decent instructions for them.

For instance their instructions say this:
"After installation of Zoom Page WE, there will be a new icon on the main toolbar with a blue badge showing the current zoom level."

That is NOT true. There was no blue icon on the toolbar (and they should have shown a picture of the icon to let us know what it looks like).

Here is how to make that icon appear in Firefox version of Zoom Page WE:

Click on the Firefox Extension icon which is on the Firefox Toolbar. Right click on Zoom Page WE and choose "pin to toolbar"

Dommage mais ce développeur a abandonné ce module qui était l'un des meilleurs, autant celui pour Firefox que celui pour les navigateurs Chrome/Edge. Il commence à disfonctionner même sur Firefox maintenant vu qu'il fonctionnait déjà assez mal sur Edge.

I am totally enthusiastic about this extension because it allows you to enlarge the font on a homepage on a per-site basis. I have been looking for this for a long time. I was always annoyed that there was no extension for Firefox like Zoom Text only for Google Chrome.

works perfectly

Works for me.

Most important add-on/extension ever, anywhere. I avoid all browsers that can't do exactly what this lets Firefox do.
