If you are medical technical user who is frustrated with spell checkers that default to American, seek no further.

This medical dictionary is a combination of a regular dictionary, a pharmacopoeia and a medical word list.  While the file uses British condition and procedure spellings (e.g. colourblindness) it is specifically tuned for drugs that have been approved by Health Canada (e.g. Gravol, Urispas, Dabigatran etc.). Some Australian and UK specific drugs and spellings are present as well (e.g. Paracetamol, Pethidine etc.) to make it more generally useful.

Risk impact

MedSpell is safe to use. It does not request any sensitive permissions.

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, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

MedSpell has earned a fairly good reputation and likely can be trusted.

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 Browser Add-ons, 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, especially ones with higher risk impact and/or higher risk likelihood.
