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?

After a recent Microsoft update, FF Picture-in-picture now broken. Will not detach from viewer, instead expands much larger beyond screen. Attempts to restore pauses video. Problem not just in YouTube. FF; 122.0.1, W11; OS build 22621.3155

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.

While hovering over a Youtube video it shows the full video title as "hover text" if the tab is focused. However, if something else, even another Firefox window is focused hovering no longer shows anything. Is there some kind of setting to change that? I figured it could be browser and Youtube specific because Chrome shows it on Youtube even when not focused, but neither browser shows it on Google search for example, but I'm not sure.

I was able to customize my new window to display www.google.com however I only have the option to select "Firefox" or "Blank" for new tabs. I would also like new tabs to open to www.google.com. How can I do this?

‘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?

I use several add-ons in firefox, and largely they feel trustworthy, but I dont have any means for limiting the scope of what they are able to do, the manifest tells me what they can do and thats it. I have read through this page https://support.mozilla.org/en-US/kb/permission-request-messages-firefox-extensions, but I have had a hard time even understanding which permissions let an add-on make network requests.

Barring the ability to actually stop add-ons from making network requests is there any visibility into what requests are being made by an extension, or all extensions in the browser?

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?

bold textWhen I click onto Firefox, it opens a tab that says Invalid URL. If I click onto the + next to it, it opens up into the firefox browser. What can I do about the original tab??

After update, netflix shows message to update browser, see screenshot attached. And sometimes, Mozilla extension webpage does not recognize that it is opened on Firefox browser, see screenshot attached. Firefox version - 122.0.1 MacOS version - sonoma 14.2.1

I don't know in which version exactly it happened but a few weeks earlier i was able to edit cookies like we can on all other browsers, but today suddenly i cannot.

I expected it to be a simple double-click and i can edit the cookie key name or value but it doesn't let me edit, it opens the detailed view about that cookie. I looked EVERYWHERE and could NOT find any way to edit the cookies for hours and this is really frustrating as a dev. This is important to troubleshoot many kinds of bugs when I am developing an app.

Hello, my mac ran out of battery. When I restared it, the firefox page restarted, but I can't see it. When I click on it in the app scrolling menu, nothing turns up. It's like it is there, but as a ghost, invisible. When I close down firefox, and restart, it's still exactly the same. I had hundreds of tabs open there, and I don't want to loose that session. When I open a new window, it works, but I can't make the prevous one appear. What is going on, what to do? I'm quite desperate about it, already spent hours looking for solutions.

"Verification of this link failed due to an error" when selecting a hyperlink. I then select "Skip verification" and the link is made.

This happens on all hyperlinks. Has been happening for at least 6 months.

How can I fix or prevent this message? Thank you.

Everytime I look up something and it has a map attached to it and I click on the map, I get Google Map or MapQuest and the map is there for 3 seconds and then it looks like the attached picture. So I open up maps in its own tab and type in the address and I get same results. But if I use either of them in edge, I have no problems. I only have Mate Translate on in add ons. So I have no idea what is going on. I reset cache as I had read that from a post (though their issue was similar but not the same) I would appreciate any and all help you can give me. TYIA

Hello,

since this morning, my gmail account doesn't work when I use Firefox on my laptop. After accepting my email address and password, it says that my account is temporarily unavailable (see annex).

But my Google account works perfectly with Edge on the laptop and on my smartphone and tablet.

The problem remains even after restarting the laptop and launching CCleaner

Thank you in advance for your help.

Best regards,

Andrea Forti
