I returned to using Tidy Read Rated 5 out of 5 stars

In 2012 I wrote:

Next to Flash Block, this is my favorite add-on I do not like Firefox 9.0 because Tidy Read does not work in it yet.

November 2013:
Here is an update. Since Tidy Read was not updating along with Firefox, I eventually left it to use the Reader add-on-- which was quite elegant, but again, became increasingly unstable with new Firefox updates.

Out of frustration, I returned to read the comments here, along with older suggestions to keep Tidy Read, which I am following at my own supposed hazard.

With the help of the checkCompatibility extension-- I have been able to reinstate Tidy Read, and am using it on Firefox 25.0.

Thus far, I haven't been bothered by any problems. It seems that Tidy Read does exactly what it was intended to do. I cannot understand at all why it is not routinely offered with later firefoxes.

Again I would like to say thanks for Tidy Read!
