Good idea, only sometimes useful, as usually content is much shorter than the whole page length. It doubles time of scrolling and displaying of Google Maps and Street View lines, so I uninstalled it. Black and white list option is needed.

EDIT to answer: % wasn't shown on a map, but after a few tests, with the add-on switched on and off, I'm sure of the effect.

an excellent extension that's absolutely essential in my opinion. It's unobtrusive and provides an exact
percentage of how much of a page you've read before vanishing.

It's particularly useful if you value *screen real estate* and prefer non-distracting elements in your daily workflow.

It works as intended, but it would be better if I could change it's size, I use a large monitor with low (page) zoom and I find it a little bigger than how I w'd prefer it to be. Otherwise, it works as intended, very useful for sure.

exactly what i was looking for. good job ccdoub!!

It is very good!
But there is one thing he don't do.
Does not work with "firefox reader view" (F9 button) = plain text reader view.
It does not display any percentage in the plain text viewer (F9).
I need to know the percentage when I read my study texts.
Please make it compatible with "Text reader (F9)".
Please! Please!

For years I have used many extensions, never wrote a review before.
This is a Really useful addition. For some time I have been wanting to quickly find my scroll place on large articles. This helpful extension gives me easy control over the web page

Can you provide a feature to hide the scroll bar?

Simple and effective add-on useful for people like me who completely hide the huge scrollbars in Firefox Quantum. In addition, in long pages of text it helps to remember the position of the most important passages. Thank you.

In some web sites the percent number is not on top but remain behind on some page element.
This happen on Netvibes and Reddit, on Techdows.com the font change.
Thanks.

EDIT: The version 1.3.2 works perfectly on Firefox 63beta. :-)
