Review summary

Most reviews praise CSS Override for being simple, fast, and effective for site-specific CSS tweaks (including font changes) and for centralizing overrides. However, there are notable downsides: inconsistent site reliability, YouTube-related quirks, injection timing delays, and a confusing editor with a need for better guidance. Overall it’s useful for straightforward CSS work, but reliability and editor usability could be improved.

Pros

Works as advertised and generally reliable across many sites.
Simple, fast, and easy to use (KISS) with a minimal interface.
Useful for precise, site-specific CSS overrides and for centralized management of your overrides.
Helpful for typography tweaks and font changes on pages.
Does what it says on the tin and provides quick feedback for straightforward CSS work.

Cons

Inconsistent availability: reported as not working on several sites and some users say it stopped working recently.
YouTube-specific issues: autoplay can be affected and layout tweaks may behave inconsistently.
CSS injection timing: changes are applied too late, after the page has loaded.
Editor UX and guidance gaps: confusing blank editor, lack of hints/manual, requests for a linter or better styling tools.
Hard to manage overrides across many sites: lack of a clear overview or centralized management for all site-specific rules.
