Hello, That sounds odd. I've just tested on my end and I'm not getting the same problem. I suspect that means that there is a specific issue on your installation of Firefox. Could you please try disabling all your add-ons (apart from the spell check dictionary) and then test again. [[Disable or remove Add-ons]] Do you still have the same issue? If not then I think one of your add-ons is causing the problem. Re-enable them one at a time and test to see which one is causing the problem. If you do still have the same issue then I suggest doing a Firefox Reset. This will restore Firefox to its default settings. Your personal data (history, bookmarks etc) will be saved but you will need to reinstall your add-ons. [[Reset Firefox – easily fix most problems]] I hope this helps. Let me know if not.
