Features & Capabilities

Korektor Spellchecker extension allows using Korektor service (spellchecker and occassional grammarchecker developed at Institute of Formal and Applied Linguistics, Charles University in Prague) on any editable input fields of web pages.

The extension allows either directly correcting the content, or showing a dialog with suggested corrections. Note that the dialog with suggestions is injected directly into the original page, so there can be various problems on untested sites. However, the extension seem to work fine on many sites.

Although the sources of Korektor service and this extension are available under BSD-3-Clause license, please respect the CC BY-SA-NC licence of the spellchecking models.

Korekor service is described at https://lindat.mff.cuni.cz/services/korektor/ , the Korektor itself is available from http://ufal.mff.cuni.cz/korektor .

Is Korektor Spellchecker 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.

Korektor Spellchecker requires very minimum permissions.

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.

Korektor Spellchecker is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
