I know this thread is somewhat old but, I just wanted to confirm that this actually worked for me. I've been trying to figure this problem out for days now but, it's finally fixed thanks to this thread. This problem occurred when I disabled the Google App from my device. I didn't notice the problem had started until, I had enabled the Google App again.
Those of you who are dealing with the same problem, please follow the instructions listed above on booting your Android device in "Safe Mode". Please be advised that it won't actually fix this issue unless, you physically open your recent tabs while operating your device in "Safe Mode". The first time I had tried this method it did not work for me because, I didn't open my recent tabs to check it while my device was in "Safe Mode". When I did it a second time, I opened my recent tabs and saw it reappear which seemed to fix the issue.
Anyways I'd like to say thank you to, N4Newbie for bringing this to the forums attention. I've tried fixing this problem for the last few days but, couldn't figure out why this was happening? After getting so frustrated over this, I finally decided to do some research on it and, well...here I am lol! Well the good news is that, this problem has lead me into creating an account here and now I'm a member...whoop! whoop!
Now I can scroll between different tabs again without seeing an annoying message about, not being able to add the Google search widget to my recent tabs menu. Last time this problem had (occurred) happened to me, I had to perform an entire factory reset on my tablet because, I didn't know or did I have any other solution at the time. Well if there's one thing I know for sure it's, you sure do learn something new everyday, that's for sure...lol! I'm just happy to know that I didn't have to do another factory reset...phew!
All I know for a fact is this. The next time I'm having any issues or have any concerns, I know what website I'll be returning back to. Thanks again to N4Newbie and to anyone else who helped, to put the word out regarding to resolving this issue. Everyone who supplied this thread/topic with such accurate and vital information, you all are awesome.Thank you very much everyone...cheers!
