User reviews
Pros
- Effective color customization for easier reading, especially for users sensitive to bright backgrounds.
- Functional and useful for customizing text and link colors on individual websites without needing CSS.
- Works on the add-on store and generally performs its intended function.
- One of the few add-ons that offers extensive color scheme customization.
Cons
- Lack of ability to create or customize color schemes freely; relies on a poorly designed color scheme generator.
- Performance issues such as slowing down websites, similar to Dark Reader.
- Problems specifically with YouTube: text overlays are hard to read regardless of filter settings, making usage frustrating.
- No simple per-site toggle or quick on/off switch in the panel icon, which reduces ease of use.
- Frequent glitches and needs updates, especially concerning compatibility with YouTube.

doesn't let you create your own color schemes instead uses some bullsht "color scheme generator" which is badly designed.
to the reply: hmm I wonder why people wanted simple colors? is it maybe because THERE IS NO WAY TO INPUT A COLOR YOU ACTUALLY WANT AND YOU JUST HAVE TO EYEBALL IT

I can't read white text on a black background without my eyes hurting a lot so this has been AMAZING.

Extension safety
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk
impact extension cannot do much harms, whereas a high risk impact extension can do a lot of
damage like stealing your password, bypassing your security settings, and accessing your
personal data. High risk impact extensions are not necessarily malicious. However, if they
do turn malicious, they can be very harmful.
Midnight Lizard requires a lot of sensitive permissions. Exercise caution before installing.
Risk impact analysis details
- Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious.
This is determined by the publisher and the Firefox add-on reputation on
Firefox Add-ons Store, the amount of time the Firefox add-on has been
around, and other signals about the
Firefox add-on. Our algorithms are not perfect, and are subject to change
as we discover new ways to detect malicious extensions. We recommend that you always
exercise caution when installing a Firefox add-on.
Midnight Lizard has earned a fairly good reputation and likely can be trusted.
Risk likelihood analysis details
- High This extension has low user count. Unpopular extensions may not be stable or safe.
