Top 5 Netflix Chrome Extensions for 2025: Binge Better

User reviews

NflxMultiSubs 2021 is praised for effectively displaying multiple subtitles simultaneously, assisting language learners, and being free and open source. Users appreciate its clean interface without extra clutter. However, recurring issues include subtitle overlapping, especially in certain shows, limited subtitle customization (color and width control), occasional inaccuracy in subtitles, and functionality problems when skipping episodes requiring refreshes. Despite these issues, many users find it superior to alternative paid or freemium extensions.

Pros

Works well and effectively displays multiple subtitles simultaneously.
Free to use with no hidden fees or payments required.
Open source and maintained by the community, providing a trustworthy option compared to paid competitors.
Helps users with language learning by showing dual subtitles.
Clean and simple interface without visual clutter.

Cons

Subtitles sometimes overlap, especially when the main subtitles are not fixed in position.
Subtitle settings like text color and width control are limited or reset unexpectedly (e.g., color resets after restarting the computer).
Does not work properly when skipping to the next episode, requiring manual refresh or resetting.
Some translations or subtitles can be inaccurate or slightly off compared to the actual dialogue.

Recent reviews

this is really well done! I tried to develop something similar vibe coding with ai, but mine relies on translations api from google which lags, the speed on this is basically same as the native subtitle! I gave up working on mine and just downloaded this haha I do wish this has width control: so that I can prevent the native subtitle from forming into 2 lines I also have notice the text color for the 2nd subtitle works only on English.

doesn't work, the subtitles are always at least half wrong compared to what is actually being said.
