Following a recent Firefox update, 1.48.0 I think, the search box in the middle of the page no longer works, any attempt to type there ends up in the address bar. I have tried setting "browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar" to false and other suggested fixes on the internet but it made no difference. I am running Windows 11 Pro, fully updated. Hope you can help Regards Keith

I set the about:config settings when I got the new computer early last year. It's been working fine. Suddenly, searches are popping up again to the urlbar.

browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar is still set to false. Keyword.enabled is still set to false.

I see a couple of site references to browser.fixup.alternate.enabled, but it doesn't exist.

How do I get FF back to proper search in the search bar?

Hi Guys,

I have an issue. I noticed now that if i click on one of my 300 tabs of website tabs, it automatically goes to some domain reseller and removes the whole link / information on the link that shows which tag or data i had on that link in the tab. If that makes any sense?

I hadnt yet gone through renaming all the tabs when the website changed domainbs and now i am unable to as the minute the tab wakes up from beind discarded, instead of coming up as can not find website (at which point in the past i could just change the 2 characters to the right domain), it goes to the domain reseller and removes the whole link / data that it used to point to.

Anyone know of a way i can do change the links on a mass scale of all the tabs i have?

I've been using Firefox for a long time, but recently, browsing YouTube has become a nightmare. The newsfeed lags significantly and scrolling is not smooth at all. Interestingly, the same site works perfectly fine on Brave and Chrome. I've tried clearing the cache, but the stuttering persists. Please optimize the hardware acceleration and AV1 decoding for mobile devices. Hoping for a fix in the next update! Also sometimes YouTube videos don't play. But the same video plays in another browser on the same internet.

Today (February 25, 2026) I received an email notice, apparently from Mozilla Monitor, advising me that my "Email addresses, Partial credit card data, Passwords, and Phone numbers" had been exposed in a data breach at Canadian Tire. This email seemed legitimate (the sender was breach-alerts@mozilla.com), but since it gave me a link to login to Mozilla Monitor, my first concern was that this might be a phishing email and it would be dangerous to click on that link. Instead, I went through the Firefox settings to login to my Firefox account and from there, I checked what Monitor had reported. The Canadian Tire breach was not listed there. However, when I went to haveibeenpwned.com, the Canadian Tire breach was listed there. It showed that the breach occurred on October 25, 2025. So why was the breach not listed for me on Mozilla Monitor? And why would I have received an alert from Monitor 4 months after the breach? Was this breach alert notice actually a phishing scam perpetrated by someone using the information from haveibeenpwned.com as bait?

I went to [https://support.mozilla.org/en-US/kb/firefox-backup] and under "Create a Firefox backup file" at step 3 it says, "Scroll down to Backup, and click Manage backup" but when I went there no such "Manage backup" option exists as you can see in the attached screen capture. So what gives? How can I "Create a Firefox backup file"? I am using Firefox v147.0 (64-bit) on Windows 11 Please instruct. Thanks RJB

My toolbar disappeared in January very disappointed because I don't want to take my computer to the fix it man here in town when It was not something I did but rather came with an update.

I use LastPass to store lengthy passwords and auto open websites. After the latest Firefox update (148) when I click to open a website, the entire LastPass vault page just flickers and returns to the same vault page.

I have vertical tabs turned on. Say i want to watch a movie, i press F11 or fullscreen to open it fullscreen. It makes the whole page fullscreen, but the vertical tabs remain still on the left. I want that fixed so that vertical tabs are hidden when its fullscreen.

Since the latest Firefox latest update yesterday (02/24/2026), each time I try to open a new tab in Firefox it crashes. I get a "gah, your tab has crashed" message but when I hit the "restore" link nothing happens. How do I fix this at my end? Thank you.

I use siscom.net for my emails. The pointer doesn't seem to open the emails. It changes into a finger on a hand and doesn't trigger the opening of the emails. I'm using Windows 11.

My Policies.Json can only block 1000 websites. Nothing after the 1000th entry is blocked. Is there a way to remove this limit?

Firefox 150 on Windows

Thank you
