I have an e-mail in my TB in-box. The mail contains a hyperlink to Facebook. When I click on the hyperlink, I get the message copied above in the Subject of this problem. In almost all cases, if I re-click on the icon in the e-mail, the re-click takes me to the desired URL in Firefox. My Thunderbird is 128.11.1esr (64-bit). Why is the first click producing the error message? Would there be anything in the TB Error Console?

I use Mozilla Firefox with Duckduckgo. This is very much my preferred setting...just not the way it's working now. Ann Marie

Experiencing an issue on the Facebook website where it's skipping/jumping ... Anyone seeing this? I did a screen recording of it.

I like Mozilla Firefox as a browser and it was working fine until an update two days ago. I normally due the updates primarily for security reasons not performance reasons. I did the update and Firefox will not connect to the internet at all. Since the update, Mozilla crashes when I try to connect with any page on the internet. The crashes are immediate; I cannot connect to any website at all. As anyone else had this problem recently and were you able to solve it? Unfortunately one cannot contact Mozilla directly for direct help with major problems such as this. I appreciate any ones help on this. It appears to me this latest update is the problem so past solutions may not work but I will and am trying them.

Today: DevTools crashed many times, and I’m facing unusual issues. I cannot call through Messenger and cannot connect for video calls. Also, DevTools is not working, even though Firefox Developer Edition is quite good and healthy. Even Firefox is not working well. Please fix this issue quickly.

OLD ISSUE

My Firefox is using a lot of data; I don’t know why.

I am not using Firefox, and it is not running in the background, yet it is always using the internet. So what do I need to do in this situation? I tried to stop the internet connection using outbound rules, but it did not work. It is still using the internet. What is the reason my browser has high data usage? I have high data usage; in fact, in the past 12 days, we've used 30+ GB of data.

Win11 Firefox 138.04 It appears some of the shortcuts on the Newtab page are preloading somehow.

Where are these coming from? Sidebar is off. I have all preloading off, all suggestions of every sort off, any predictive anything off.

I am not experiencing this on my win10 machine.

How do I stop this?
