Rated 4 out of 5 stars

An exceptional addon, but it's lacking a pretty basic feature as far as I'm concerned. That is the ability to change the text-font size. If said option gets added into the configuration menu, I can't imagine anything else to ask for.

This review is for a previous version of the add-on (4.1.1-signed). 

1) The first reason for this option being absent is that there are many settings that override or modify a given font size in pixels (application zoom, page zoom, text zoom, minimum font size, CSS transform, font-size scaling). Adding another size to that merely leads to confusion.
2) The second reason is that within Column Reader I try to make only those changes to the layout which are needed for a column view, in order to prevent unpredictable styling conflicts.

I'm willing to look into this again to see whether I can guarantee a single absolute font size (or compressed range of absolute font sizes) for all text (not including compensation for minimum font sizes as set in the Firefox preferences).

Please donate to make it possible.
