I regularly post music history on Google Plus using video from YouTube. As i have been doing this since 2013 I use hashtags to relate between artists and genres. Now when I post (since 7 January 2017) using Firefox (Linux) the spell checker queries the hashtag contents. I have tested the same post using Firefox & Chrome, with no spell check query appearing in Chrome. However Chrome crashed (again) on posting the article. Is there something in the new posting system in YouTube / Google Plus that is affecting the spell checker in Firefox 50.1.0?
