Review summary

Ultrawidify can greatly improve video viewing by removing black bars and enabling 16:9 stretching on popular sites, including 4:3 content on older displays. When it functions, it provides smooth fullscreen without crops and offers adjustable stretching options. However, several reviews report stability and performance issues, including grey screens, unresponsive tabs, lag, and flicker during fullscreen use. Reliability also appears variable across versions, with some noting regressions after updates. Overall, it delivers a notable improvement for many users, but persistence of bugs limits trust.

Offers configurable stretching options, including a 16:9 stretch hybrid, in the settings.
Helpful for 4:3 content or CRT setups by stretching to widescreen.

Cons

Stability issues: can cause a grey screen with an unresponsive tab, sometimes requiring a browser restart.
Performance problems: lag, flicker, or slow behavior on some videos and during fullscreen transitions.
Reports of reliability regression over time, with some users noting bugs after updates and that older versions seemed more stable.
