Firefox's dictionary has the same issues/limitations, with most of the same words being missing. It is actually a legitimate weakness of the browser (particularly compared to Chrome which has fantastic dictionary). You could use something like e.g. Grammarly but their privacy policy is frankly shocking[0] (they take & store all text you ever write for as long as they like for any usage that they like, and record every site you visit, your geographical location, device info, third party cookies, etc). > we may keep some of your Personal Data for as long as reasonably necessary for our legitimate business interests # > you may contact Grammarly to request deletion of your data. Grammarly will evaluate such requests on a case by case basis, pursuant to our legal obligations. # > Does Grammarly review User Content? to improve our algorithms as described in the User Content section of our Terms of Service. # > Does Grammarly share my Information? We need to do so in connection with a merger, acquisition, bankruptcy, reorganization, sale of some or all of our assets or stock, public offering of securities, or steps in consideration of such activities (e.g., due diligence). In these cases some or all of your Personal Data may be shared with or transferred to another entity, subject to this Privacy Policy. Etc etc etc etc. [0] https://www.grammarly.com/privacy-policy https://www.grammarly.com/privacy-policy
