Fórum da Comunidade de Firefox

Today I have installed Pocket on one of my Windows PCs in the Firefox browser. I got the symbol on the address bar and it works. Now I want to install Pocket on another PC, but I don't get the symbol. Without symbol I cannot use it. I can login to Pocket on the second PC and open saved URLs, but I cannot add Websites to my Pocket account. How do I get the symbol?

I take a lot of screenshots using Firefox's built in screenshot tool to share with my friends. After a while it slows down my Photos folder and I move them elsewhere. However, I cannot move, delete, or even rename any of the 18 photos shown in the photo below. They are all from Twitter/X, but this error does not apply to every screenshot from Twitter - I was able to move or delete most of them. However, it is ONLY happening with photos from Twitter. They are not Read Only so I don't know what the issue is. I'm not having this issue with Windows Snip tool, only Firefox Screenshots.
