User Reviews
Reviews are mixed: multiple users praise the add‑on as simple and effective at stopping auto‑translation, while several others report it fails to work (especially for front‑end JS or navigator.language). Users also mention confusion or issues when adding/saving languages, with one advising to use Firefox preferences instead. Pros
- Works for many users — does what it says and is effective
- Simple and easy to use
- Can prevent websites from auto-translating content
Cons
- Inconsistent functionality — several users report it doesn’t work for them
- Does not change navigator.language / doesn’t affect front-end JavaScript
- Adding or saving new languages is confusing or broken (missing save button); may require using Firefox preferences

Works for me, needed it to stop websites from translating themselves and it did just that, so thanks.

Is Quick Locale Switcher Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Quick Locale Switcher requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
