Review summary

Users appreciate that the add-on automates switching spellcheck languages and saves manual switching; many say it works well. However, multiple reviewers report inconsistent behavior (fails, needs restarts/reinstalls), site-specific mis-detections (notably Reddit/Facebook), delayed activation, and perceived degradation or lack of maintenance over time.

Pros

Automatically detects and switches spellcheck language, removing the need to switch dictionaries manually.
Many users report it works well and is a practical solution for multi-language typing.
For some people it functions reliably after initial setup or a restart.

Cons

Unreliable or inconsistent: several reviewers report it fails, stops working, or requires reinstalling/restarting to recover.
Site-specific mis-detection or overrides of manual language settings (reported especially on Reddit and Facebook/old Reddit text areas).
Delayed activation: may need you to type a few words before it switches, so it’s not always instant while typing.
Appears to degrade for some users over time; a few reviewers suspect it is no longer well maintained.

2025-09-11	Qu*****	This plugin used to work, but it seems to be unmaintained since 2023. For me, it caused problems on notion.so, leading to thousands of warnings and a huge memory leak. For anyone looking for a reason why Notion may be unbearably slow and produce these warnings, disabling this extension may the the solution. This is Notion's warning when this extension is enabled: NOTION WARNING Reverting mutation of attribute lang from "null" -> "en" in component undefined MutationRecord { type: "attributes", target: div.notranslate, addedNodes: NodeList [], removedNodes: NodeList [], previousSibling: null, nextSibling: null, attributeName: "lang", attributeNamespace: null, oldValue: null }

2022-03-18	ka*****	Doesn't work at all. I wanted to use it to automatically switch between English and Hungarian, but it even messes up sites that have already been manually set. (Tried on Reddit and Facebook.)

2021-11-29	Ei*****	Oh my god this works so damn well! I have been so annoyed by constantly having to manually switch between spell-check languages for so long, but never found this add-on before. Thanks so much for this great Add-On Jacob! :-)
