I just want to stop a piece of my own history from being shown on "Firefox Suggestion", which was made with a firefox browser on my previous device and is relatively private.(I know I can do this by modifying "Search Suggestions->Show search suggestions ahead of browsing history in address bar results", but I would like to preserve the function itself). That device is permanently unapproachable, and so is that browser. I tried "Clear recent history -> Everything", but it didn't work as expected and that is still shown. I think clear all my history(not only those made on this currently used device) may help, how can I do it?

I used to click on a bookmark to open a new window and load the link, but now it's loaded directly into the original window, how do I revert back to the previous state?

I have enclosed a screenshot showing what happens when I want to go to a new tab on the two computers I use most often. One is my desktop which has Windows 10 Home. The other is my laptop which has Windows 10 Pro. The Windows 10 Home was installed most recently and is the latest version of Windows 10, my tech guy told me; and also the latest version of Firefox 123.0.1. The laptop version of Windows 10 is older. The Firefox version is also 123.0.1.

My hope is that there is a setting I have not uncovered that lets me put some kind of mark on a new tab, as my laptop has had for a few years. This makes it very easy to open. The newer, later Windows version but same Firefox 123.0.1 on the desktop must be right-clicked in the space to the right of any open site, and then the user must scroll down to the "New Tab" line and click on it. Obviously this requires my user clicks and more time, simply to get a new tab that gives me a blank site that I prefer.

I appreciate whatever guidance or suggestions anyone can give.

I try to synchronize my firefox on my new laptop but it gives 5 minutes to enter the code, the code arrives afer more than 15 minutes.. The help syggests if it not works to use another mail address but I cannot delete the mail adress, every time I want to synchronize the existing mailadress appears with a password field and the adress cannot be changed. Can someone help me to solve this, is there an other way to synchronize?

Right after a Firefox update on or about 3-8-24, when I click on the network icon on the Windows 11 system tray, the network icon in the Quick Access area is no longer there. But when you click on the network icon you see some soft of video player controls if you have a video open in Firefox, and the network icon is gone! I need to have the network icon restored. And BTW, when clicking the pencil icon to add something to the quick access, there is NO network icon to be added! Its not there, in fact, the "add" is greyed out, and the option for adding "network" no longer exists. I don't really like the video player controls that show up like in the photo, and would like to be able to make that go away.
