Hello, In a previous version of firefox, I could right click within a text area for example, which would allow me to check my spelling. Since upgrading (which was actually from a higher Beta version, to the latest current stable - a new profile was created), I had not had this option. As you can appreciate, it's a very handy tool to have, so I have been attempting to get this function back today. Within my language section, initially there was only 'English [GB]', which was as it should be. I had 'check spelling as I type' checked also. This did not automatically check as I typed. It did not check at all, not could i right-click to check spelling. I have since added 'English [US]' to see if this would then allow me to remove and reinstate 'English [GB]', but it did not. I then added a third option which was 'English [CA]'. The config allows me to remove only 'English [CA]', which when pressed removes it from the list, but by pressing the 'set alternatives' button again, you can see that it has returned. I have since managed to get firefox to check spelling in English [GB] by adding 'British English Dictionary (GB)' (https://addons.mozilla.org/en-GB/firefox/addon/british-english-dictionary-gb/), but now I am also stuck with English US and English CA. EN-US does not allow it to be removed whatsoever, even though it was only there after I manually added it and EN-CA allows me to remove, but returns. No option to apply and restart firefox appears (I've seen this appear in another user youtube video on the subject). Closing and opening makes no difference. How can I removed English US and English CA please? 6 images attached, in sequence order. Between images 3 and 5 you can see CA being removed and returning (and also no option to remove US). The last image is what I am now trying to get rid of.
