This often doesn't work on websites and only have four sizes you can chhose from, it needs to let teh user adust the suze they need and do some absolte setting theat fources a page to have the font size changed.

Does what it promises with a simple interface, namely adjusting font size instead of enlarging everything with the zoom function. Being able to reset to the initial font size would be a useful addition.

簡單實用

Only lets me enter 1 of 4 values. No way to enter own values.

Overall good but it is missing 2 things:
1) A way to choose the size instead of the 4 standard sizes
2) A way to disable it without going to manage extensions.

The last one is because i use it for reading websites that don't have a change font size or it is too tiny. For normal websites it becomes a problem.

Does exactly what I was looking for where all other add-ons failed. Grazie.

I am unable to bring up the font change menu. I don't know where it is.

Why on earth does this extension not let you customize the font size? It's the only extension on firefox that lets you change font sizes, but for some unknowable reason the developer decided to limit you to one of four arbitrary font sizes instead of putting a text box. The screenshot shows the 18px, 20px, 22px, and 24px buttons, but it doesn't show that those are THE ONLY SIZES YOU ARE ABLE TO USE!
