Thanks to Jarrad, this extension is very useful.
It has only one problem: compatibility with new Firefox for android. I added this extension to new Firefox, but it didn't work :(

Kind of crazy that you need an add-on for this sort of thing. Anyway, works great. Thanks Jarrad!

Just a lifesaver!
This functionality, however, should be in Firefox by default.

Works great for me. Helps me read Oracle JavaDoc conveniently. Thanks!

Superb extension to read anything

Cool. Its working on my android phone.

this is an essential addon!
Thank you!
