I just saw in the upper right hand corner that something activated.
I was on YouTube and in the upper right hand corner there was a small splash screen that said Activated with words underneath. It did not show but a couple of seconds so I couldn't read what activated.
I did not change anything. How do I find out what happened? I don't see you offer any logs.
PS I don't know if it was YouTube or not Firefox. But I have never seen it before.
It was rectangle with cream white background, black font, Activated was in large font, under it was smaller font. It covered the hamburger and 3 of the icons in your toolbar. It was half on the viewable window page (YouTube) and half over your icons.

Check for any unfamiliar add-ons. Either:
- click the Extensions button (puzzle piece) on the toolbar > Manage Extensions
- Ctrl+Shift+a (Mac: Command+Shift+a)
- Command+Shift+a (Windows: Ctrl+Shift+a)
- "3-bar" menu button (or Tools menu) > Add-ons
- type or paste about:addons in the address bar and press Enter/Return
In the left column of the Add-ons page, click Extensions. On the right side, find the "Manage Your Extensions" heading.
If there is at least one extension before the next heading -- "Recommended Extensions" -- please continue:
Then cast a critical eye over the list below that heading. Any extensions Firefox installs for built-in features are hidden from this page, so everything listed here is your choice (and your responsibility) to manage. Anything suspicious or that you just do not remember installing or why? If in doubt, disable (or remove). For your privacy and security, don't let mystery programs linger here.
Any improvement?
Note: Sometimes extensions can frustrate access to this page. In that case, first restart Firefox in its Troubleshot Mode and then try again. See: Use Troubleshoot Mode in Firefox -- Open, not Refresh.
