Firefox Community Forum

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?

It's frustrating, no matter what you set, the search always jumps to the address field. I enter known addresses in the address field. I SEARCH in the SEARCH FIELD. And I want that in the future too. How do I make it possible, permanently, to be able to search in the search field??? The following doesn't work (anymore).

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste handoff and pause while the list is filtered

(3) Double-click the browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar preference to switch the value from true to false

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

Again Firefox? Again? Third time the charm or something? Stop this ridiculous handoff from Search bar in page to URL bar for searches. It's not safe, helpful, or anything other than confusing. Give us the Option. Seriously, it is why we use FF in the first place, Despite tons of companies not supporting it well for website access. I am mad and literally after decades of use am making my first formal complaint. Fix This Please. Add a bunch of appropriate curse words here please. Thanks and keep up all the other great work.

I am running Windows 10 on a desktop pc. I have Firefox for Windows 148.0. I am editing a website on Joomla 5.4.3. To edit pages in Joomla, I use the TinyMCE editor. Since today, whenever I open a page in the editor, the editor keeps reloading constantly which renders the editing impossible. After I close the editor, the browser seems to lag for 5 to 10 seconds, before returning back to its normal, problem-free behaviour. This behaviour is only happening in the Firefox browser, not in others on the desktop.

I switched to my Macbook, which still had Firefox for iOS 147.0.4 running. There the above mentioned behaviour didn't occur. But when I updated Firefox for iOS to 148.0 the behaviour did start to occur.

So, I guess it is a bug in version 148.0? How can this problem be fixed?

I am running Firefox 148.0 and Thunderbird 148.0. I am in the process of moving everything to a new (to me) computer that will run Windows 11. When I start Firefox from the start menu or the taskbar everything runs as expected. I have the Adblock Plus extension plus several others running. If I click on a Hyperlink in a email in Thunderbird instead of opening in a new tab into the currently open copy of Firefox as it did on my old computer running Windows 10 it opens in a new window with no extensions. I am assuming that I have something set incorrectly. Any help as to where I should look to fix this issue would be greatly appreciated.

The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

I can't login to my Facebook account? But I can login to other browsers,

Can you please help me on this.

Thanks.

after confirmation and approval nothing changes on screen.

I use Tab Groups quite frequently. I am not a fan of the new functionality built into it.

So now if I close a group, one tab within that group will stay open if I was just on the page. It will not close until I go to another page and click close on the tab group again. Frustrating! Why cant I just open and close as usual?

Is there a way to get rid of this feature and still keep tab groups?
