Me, too!
I love to do screen grabs of new words I look up - tagged with "new words" and the year. Makes for an interesting retrospective. But I don't need the rest of the irrelevant Google search - just the new word and its definition. This used to work fine. Now I get maybe the top left (? I'll pay attention next time). but certainly - not what I grabbed - just an erroneous chunk.
I uninstalled the EN GC extension, rebooted, downloaded the latest and greatest, reinstalled and - WHAM! Same dealio. No change. Very anticlimactic. And super frustrating cause that was a nice, EASY little daily edification that I won't do if I have to jerry rig a daisy chain of workarounds. I'll never find. sort, organize or revisit those clips again if not for the easy breezy EN ease.
NOTE: SOMETIMES I add a note as to why I looked the word up or its relevance to a tagged project but I only annotate about half the time - and it happens 100% of the time.
