Speed only
If you only need playback-rate controls, compare range, step size, shortcut customization, site access, and how settings are remembered.
Version-aware comparison
A dedicated speed extension and UVE can both solve playback-rate problems. The meaningful difference is whether you want one focused control or a broader toolkit for speed, audio, subtitles, and reusable setups.

For long course libraries, UVE combines fine speed changes with domain memory and named speed/volume templates. See the Udemy guide and Coursera guide.
Speed is only one part of listening practice. UVE also provides subtitle and volume tools; follow the video language learning workflow.
Comparison FAQ
Yes. UVE controls compatible HTML5 video from 0.1x to 16x. The Free tier supports speeds up to 3x, while Pro unlocks the full range.
Check the other extension’s current official listing and permissions, because features can change by browser and version. Then compare the controls you need: speed range, shortcuts, presets, volume, subtitles, and per-site memory.
A dedicated controller may be enough if changing playback rate is your only requirement. UVE is designed for people who also want volume boost, subtitle tools, templates, and per-site settings in one Firefox extension.
UVE works with compatible HTML5 video on many websites. Protected, embedded, or non-HTML5 players can restrict browser extension access, so compatibility should be tested on the sites you use.
