@leisureguy Aha! Although I don't find 1Password in a search of Opera extensions, when I go to the 1Password site (using Opera) and sign in, 1Password can be insttalled in Opera. It's just not shown in Opera's own list of extensions.

Still, I would have preferred that the update not remove the extensions I had already installed.

I had Opera version 117.0.5408.53 and I was happy with it. I had the 1Password extension installed, which I use regularly.

Opera updated itself (without asking) and the 1Password extension is gone, along with other extensions. A search of available extensions does not show a 1Password extension.

How do I get the 1Password extension back? or do I just move to another browser?

This started just a few days ago. I click a cell, and a cell down and to the right is selected. In one sheet, it's down 2 rows and over 1 column; In another sheet, it's down 5 and over 1 and another down 6 an dover 4. I cleared cache and returned to that sheet and now it's down 5 and over 3.

Also, in a workbook with multiple worksheets, the tabs at the bottom have vanished.

Google Sheets work perfectly in Firefox, so I guess I'll have to use Firefox, but it seems as though Google Sheets should work in Opera. Up until a few days ago, it did. I do have latest version of Opera (78.0.4093.147). Also latest version of MacOS.

@leisureguy Problem has cleared with nothing done on my part. I didn't even exit and restart Opera — but the next time I brought up YouTube in a tab, the ad and tracker blockers were working again.

This happened just this morning (2021-04-30). I am on a Macbook Air with M1 chip running macOS Big Sur 11.3 and Opera Version:76.0.4017.94 (arm64). The shield in the address bar when I'm in YouTube shows an X and when I click the shield. I see two messages:

Ad Blocker is turned off for this site.
Tracker Blocker is turned off for this site.

There is a button for each labeled "Turn on for this site" but the button does not work for YouTube.

What happened? How do I fix?
