On my first PC, I have this specific sidebar icon in my toolbar. When I click it, the sidebar opens with Gemini ready to go. Perfect.

But on my second PC, that specific icon is nowhere to be found. Even when I go to "Customize Toolbar," it’s not in the list of available buttons. The only thing I can use is the generic "Sidebar" button, which is annoying because it doesn't open Gemini directly, it just opens the general sidebar and I have to click again.

I provided an image, where the first icon is what I want, but only second icon is available.

Just recently when logged onto Hotcopper.com.au have been getting a message that reads "This page is slowing Firefox down. To speed up this browser, stop this page." There is a STOP button, that helps for a moment or two only. When I open the program with MS Edge, the problem does nor occur. I was going to remove the Firefox App but saw the repair option. Repairing did not stop the problem. Any suggestions? John I have a near new Acer laptop running Win 11.

Shortly after upgrading FireFox, whenever I try to go to a website, like PayPal or my bank or anything else, I immediately get a large Ad/site for something frequently related somehow.

Like my bank I will get something suggesting an online bank, or ways to make banking easier. It will be a large window, covering my original window. I have to exit THAT site to get to the one I want.

It is a separate window, I cannot just X it out, I must shut down that window. Then the window that I actually want will be beneath it.

I can't figure out how to fix it.

Moderator note: This question has been edited to correct the formatting.

I am using 147 ESR and when I go to permissions and block all cookies for the site plex.tv the cookies are not blocked. If I go to the URL field and select the lock, it shows "clear cookies and site data" which means the cookies have being accepted.

Why are the cookies accepted from the site when I have set cookies "blocked"

The last update (which was VERY rocky... I had to reinstall and functionality has NOT been great since) eliminated the Bookmarks icon from the top ribbon. I've looked through settings, but find no way to restore it. Can it be restored? I now have to click the menu, Settings, and THEN Bookmarks.

I hope this is ok to post here.

My windows MSN app says this. When I select '"Open in Browser", this happens.

However, when I select "Video Hub", it works normally.

I tried clearing the cache and cookies. Reset. Uninstalled/reinstalled. I can separately access the website on Firefox.
