Not so good since the last version came out... Rated 2 out of 5 stars

Since the last version came out it's not functioning properly. Hopefully this will be resolved as I really liked it.

Just installed it as the LCARS scheme is small for someone with bad eyesight. This worked a treat, I now have the best of both worlds, LCARS interface and I can read it :)

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!
