One quick trick to bypass this issue in Firefox is to create a bookmark in your bookmarks bar for the website in the correct language as shown below:
https://www.lds.org/?lang=eng.
To do this, right click on the link listed above, click on bookmark this link, name it lds.org or another name you like, and choose to add it to your bookmarks bar. This way you avoid the challenge of needing to change the URL each time you go to the church website.
I only have the issue in Firefox, so other browsers allow me to just type in lds.org in the address bar. If you are using a different browser and having the issue, your steps may vary slightly.
I Hope this works for you.
