Great addon for blurry Windows 10, 5 stars absolutely!

Wonderful for old eyes. Dramatic increase in text darkening. Also can adjust font size, boldness, more within Firefox sourced websites. Much needed with current crop of default fine, light print operating systems.

I sometimes browse or read on an e-ink tablet screen, which feels nicer for my eyes especially for long form reading. Unfortunately sometimes the font uses a lighter gray color and so is harder to read even if on a white background. That's where this extension helps. It makes the page text much easier to read by bolding it among other things. Very useful on a screen type where more contrast is welcome. Thanks!

Life saver! Using it to work with web based zendesk. Could not see anything on their pages.

v1.5.3 now very useful, eases reading.
settings export/import would be a nice option.

Nice little add-on, but a bit limited. Can only target grey text and not less-contrast text of other colors. Does not deal with text that are too small, or link colors. I'd suggest the "Text Legibility" addon instead.

Thank You So Much Dear "Firefox user 13187237" , For This Brilliant addon , this is , one of the best needed addons in the whole internet.

it helps, tnks

Perfect for cooking websites, expecially for johnny sins one ;)!

Awesome man, works well on pornhub & xxx.com

Great job mate :)!

Nice add-on except that the "Skip links", "Skip headers" options are broken as of Firefox 62? When enabled for all sites, it works but all headers and links turn black.

Fantastic. Thank you for this add-on. It's exactly what I needed.

5 Stars. This add-on is the best option in Firefox Quantum for correcting the flawed design of websites that feature barely visible grey text. An alternate add-on with the same objective exists, but it is quite buggy in post-57 Firefox.

The introduction of the blacklist feature in version 1.3.1 further cements Font Contrast as the best add-on of its kind. Thanks to the developer for the response to my previous review, in which I had requested this feature.

With regard to the comment by Joy, below:

The icon in the address bar can be hidden (right-click it and select appropriately). Thereafter, right-click the Firefox titlebar, select "Customize..." and drag the Font Contrast icon among your other add-ons. If you ever restart your Firefox with add-ons disabled, you'll have to redo the part about hiding the address bar icon, as doing so will restore the icon. Ultimately, though, what you want is easily done.

It does seem to solve the problem of the idiotic light fonts on light background, which 20 year olds with excellent eyesight think is cool. I await the day they can't read a page because of their own code. One problem, though. The icon is right next to the URL and before the "bookmark this page" icon, and is apparently unmovable. I'd rather have it over with my other addons, which I keep to the right of the search bar. Right now it's cluttering my address bar.

Does what it says, therefore very useful. Thank you!

Ooh thank god, I can't read most websites because the text is too light! Please, keep this addon up to date, it's really needed.

Can be useful add-on for some pages, but is it possible to add 2 options?
1. to hide icon in the address bar (since Quantum not allowing additional toolbars, two icons for one add-on is now too much);
2. to set maximum font size (or exclude header tags?), so add-on don't alter big colored header lines, which make the whole page look unpleasant. Thanks.
