If you don't have satisfaction with Text Legibility, here's 2 alternatives extensions:

• Better Text View
https://addons.mozilla.org/en-US/firefox/addon/better-text-view/

• Font Contrast
https://addons.mozilla.org/en-US/firefox/addon/font-contrast-fix/

It is configurable and it seems to work well for me for the time being. It indeed makes the text more readable (more than what the "Font Contrast" add-on does).

The 1 star down is because there is no way to set options per site (whitelist/blacklist etc) and also (as the developer says in User Guide):

1. The add-on is now abandonware so no more updates to keep up with changes in websites

2. The developer uses obscured javascript code to deter intellectual property theft and for this the add-on was going to be removed in 2019 from the official firefox add-on page. For some reason it is still available however.

It does a great job on website text. However it does not increase the font size of the toolbars: bookmark tool bar, menu tool bar and there consequent texts. So I am still peeering at these (for me) tiny names and texts. I am 74 years old and my eyesight is not as flexible any longer. I treied resetting the fonts in Firefox options as well as in Windows settings. None of them address these situations. Thank you for trying.
Cheers.

Parfait pour les pages web aux caractères trop petits.

The latest Firefox Mobile update broke the app.

The Dev will only notice if I give this 1 star. In reality it is a FIVE STAR APP. So apologies to the Dev for having to bring it to your notice by this route.

Abandonware.

I love what this extension does and how it does it. It's a good design, and the live updates as you tweak the settings really helps find the optimal setting for each site.

By default the "Keep up with changing content" interval is set quite low, to a few seconds. On slow or very busy machines, this can lead to update problems. If these occur, try making the update interval longer.

However, the "Disable" check box simply does not work. The only thing it disables is the Settings window. The extension continues to apply the current settings to every tab. (It even applies them to the captions that accompany streaming videos from TED, YouTube, and Netflix!)

To actually disable it temporarily, you need to disable the extension itself. I have been doing that, but it takes longer than it should.

"Text Legibility" also lacks site-specific settings, which is a major drawback, especially for productivity sites (Gmail, Google Calendar, etc) that use custom shading and font colours extensively.

I expect the author intended it to be an elegant way to made global decisions for all sites, but made it too useful for users to want to use it like that.

We love having the ability to customize the appearance of each website on the fly, which this extension provides. We would love to be able to have custom settings for each website. Unfortunately, this is a big change in the design, and I'm not sure the author is motivated to make this change.

So dear reviewers, PLEASE BE KIND when asking the author to take that big step, and to put in those hours! This is a free extension, and the work is completely voluntary, so we need to treat the author with respect!

(5-star) Very useful addon to deal with websites that use too little contrast, set text sizes that are too small, etc. Still has trouble with text-shadow though.

UPDATE 2019-04-10: downgrading it to 2-star for now. It is causing frequent freezes which is very annoying when typing in Firefox.

With a big scroll bar that you can pop up, it is possible to quickly and easily adjust the text on any website. You see in real time what is happening, i.e. you do not have to reload the page to see the effect.

A zillion stars for wonderful Add-On!

Please add auto textwrap option

Font sice change works on my tablet perfect.

This seems to be the best add-on for making text easier to read. Thanks a ton for making it :-).

I Love the developer who just's wants a bowl of soup. And some to talk too.... Once I figured it out on Chrome I cam here to get it for my Firefox! oh yeah babbyyy!

Disable is not reliable.

For example:

1. visit https://www.logilab.org/

2. use the Legibility icon to disable Legibility

3. close the tab

4. open a new tab

5. visit https://www.logilab.org/

Expected:

- no effect of Legibility

Actual result:

- effects of Legibility

Workaround:

- enable
- disable

– but the workaround is not persistent.

I first found this problem with Legibility for Firefox, added to Waterfox 56.2.0.31_7 on FreeBSD-CURRENT.

Reproducible with Legibility on Chromium 65.0.3325.181 (Official Build) (64-bit) on FreeBSD-CURRENT.

After installation I configured settings but can't find the control after making web search results page text too dark. How can I reach settings for add on again?

Very useful Add-on but I had to uninstall it. When the app is disabled it still formats text. I have to enable it and then disable it for the original page presentation. At first I thought the add-on created a registry of visited urls and saved their settings, but that isn't the case. It would, however, be a great feature. I would continue using this add-on because I agree with the developer's premise: light gray text on a white background is completely insane. I hope the developer has some input, which I would eagerly welcome.
