We are using Firefox ESR for Oracle Applications (EBS) & after experiencing stuttering and sluggishness on Microsoft Edge Chrome, decided to switch to Firefox, hoping better experiences. Not just the experience was horrible, to my utter surprise I realized Firefox was not doing spell checking as I was typing. To my further disappointment, found the right click context menu within the text columns didn’t show me the language options either.

So, I knew that there was something drastically wrong. I checked Mozilla Firefox forums and the accepted answers were about installing Dictionary for the targeted language thatI never did in the past! However, I noticed something interesting that Instead of English US, Firefox had only English GB as available under the language section and “Check Your spelling as you type” was enabled by default. Teh noly isseu I aws heving wsa FryerFlox wll nto od tath!

After “some” time reading and failed experiments, I decided to download the “English US” as additional language mainly for the reason that my OS uses it as the base language.

After downloading English (US), automatically it become the default language for Firefox & reloading the editor page started showing language options!

I don’t have any technical details for why English (GB) was not doing spell checking or missing language settings within the Context menu. One of these days I am going to check with Firefox forums for a better answer. Until then!
