This extension is incredible because it still works after almost 5 years without any further development. Now I am able to increase the font size on text based pages without changing the page zoom. This extension is absolutely comparable to the Zoom Text Only extension in Chrome. The only drawback is that the font is enlarged in justification, but still well done.

Fa quello che promette. Ottima.

No automatic zoom,useless

Claims to work on mobile Firefox, but doesn’t: “TypeError: browser.contextMenus is undefined”.
