My default search engine was Norton Safe Search but now it does not appear as one of the options to choose. I cannot remember all of them. Bing and Google are two of them but not Norton Safe Search although I have been able to add it to the toolbar. Why is it no longer one of the options?

When I open firefox for the first time or after reboot or logout the internet doesn't connect immediately and it need almost 1 minute or more. I tried so many solutions, but they didn't work. If I reset Firefox, then the problem is fixed, but after some days, it's the same problem.

Hello; so, my brother lend me his old laptop, clean. I signed in firefox with my account and explore normally. One day, he need it back a couple days so he can work while he repairs his main machine. Log off of my account and log on in his. Now my bookmarks, historial, loggins, etc appear in his session. We think that can not be possible with separate accounts with different associated e-mail and passwords, but here we are.

There is a way to separate my things from his account? It only happens to him, i don't have in my browser his data. Thanks

When I try to open a new tab, the dot continues to move back and forth but does not load the tab. Sometimes I have gotten the message: "A web page is slowing down your browser. To stop it close the page."

I have tried fixes suggested on the web, but no help, including clearing the cache.

Thank you in advance.

The site works with Microsoft Edge, which is not my usual browser. (That's Firefox). I have tried clearing history and it has no effect. Can anyone confirm that this is a Firefox message and what it means?

I'm having problems with Firefox using 75% of processor capacity. In "top" I see many instances of "Isolated Web Co".

At the moment of this screen shot the processor is not overwhelmed, however, it will sometime jump up to 75% and the system will seem to freeze.

What is the "Isolated Web Co"? I'm thinking a virus.

Thank you.

I maintain a website that I update on a regular basis. For the past month, none of the updates have shown up in Firefox. I've refreshed the page, cleared the cache, logged out and logged back in. Nothing has helped. With other browsers, there's no problem -- Chrome, Opera and Safari all show the website updates as soon as I post them. I'm using Firefox 122.0.1 (64-bit) on MacOS Sonoma 14.2.1 (MacBook Pro 14-inch 2023). The website uses WordPress, hosted by DreamHost. I have two other WordPress websites, both hosted by WordPress, and Firefox is showing updates with no problem. I'm querying DreamHost on this as well, but I suspect they'll must say it's a Firefox problem.

‘I can't receive outlook mail today using Firefox. I receive message header but when I open it there's no message data. It works fine in Chrome. I can't forward a message it fails to connect to the server. When I try to delete messages it doesn't remove the item. Any suggestions?

Am running on linux with KDE. When I press the software shutdown button in KDE, and reboot, the tabs in firefox remain, even though I disabled that from happening in settings.

Greetings,

I just saw on line a notice about mozilla monitor and I tried the free scan. I was alarmed. My quesiton is if you have more than one email associated with you ID information, does mozilla monitor cover those different email addresses?

All of a sudden when I open a link from an email it opens on Edge instead of Firefox, even though Firefox is my default browser. Can you please tell me where I can change the automatic setting? Thank you, Maria

Hi, I have recently update my Win system with everything including Firefox. And now when I open new tab there is the same Firefox icon like always, but when I it is loading new page then its new X. When it is done with loading it changes to OK icon of the dedicated page. Is this X normal? Thank you
