Thank you!!!! Rated 5 out of 5 stars

Mozilla 44.0.2 update had tab and toolbar fonts so tiny as to be almost illegible. Many thanks for your fast update so I'm back to being able to see! Much appreciated.

Excellent Rated 5 out of 5 stars

REF: ThunderbirdBird 29.0
This add on is effective, and very simple to install and utilize. My need is related to providing instruction in part via printed screenshots, in which standard font is virtually unreadable without a magnifying glass. This add-on does the job perfectly, and is quickly and easily switched from standard to magnified and back. Thank you!

Working again Rated 5 out of 5 stars

Okay, I was quite angry some days ago because a program update destroyed nearly everything in Firefox (and could not be reverted) but the new version works with Firefox 44, icon is back again too etc, thanks for this

works as expected Rated 5 out of 5 stars

Good for scaling things in situations where you have a high dpi display and do not want to use the OS's own scaling for various reasons.

Wonderful add-on, works as promised! Rated 5 out of 5 stars

This add-on does exactly what it says it does -- and more! I was having a terrible time reading menus in Firefox and Thunderbird, and recent updates of the programs seemed to be just making things worse. While I could zoom the text on screen, I was not able to find a way to reliably view the text in toolbars and menus in either program. That has changed with this add-on! You not only get a choice of fonts to use, you also get to choose the font size and weight. I only had to increase font size very slightly (the add-on allows changes by 1/2 unit increments, which is good), but changing from regular to bold face made a HUGE difference. For those who use Thunderbird, this add-on also allows you to change the font that folders are displayed. Zooming in that program just increased the reading pane view. Now I can see menus and the folder pane clearly. Context menus are also displayed in the font size and weight I choose.

I'm in my mid-50s so reading glasses are a part of my daily routine now, but it was maddening to only need them to read the menus, toolbar items, and the like. No more! Thanks so much to the developer for making this add-on. I can see everything more clearly now, which is a good thing!

Add color and style anytime! Rated 5 out of 5 stars

This add-on gives you the incredible ability to change the color and size and style of fonts anytime you wish; there are MANY options to choose from. You won't be disappointed! I just wish this was available for other browsers such as Chrome and Opera; I certainly hope they consider this!
