I updated to Firefox 151.0 and lost many links on the title page. The "new tab" window shows only 4 rows and "6" columns of tiles. I went from 32 clickable links to 23 links. For some reason the last row has only 5 columns. How do I recover my lost links and how do I restore the look to 150.0.3? Thank you in advance.

System: Windows 11 Home, Version 25H2, Build 26200.8457

Hello Mozilla team, I am paying for Mozilla VPN with yearly subscription. Should I cancel my subscription with this free VPN? Or where is the difference?

Thanks very much in advance and best regards Karin

I just updated Firefox to version 151.0. The release notes say:

"Private Browsing Mode now allows you to instantly clear all data from your current session without closing the entire window. When you select the End Private Session button (the fire icon) to the right of the URL bar, Firefox will ask you to confirm to clear your session. Once confirmed, it will wipe all of your private browsing data and open a fresh new Private Browsing Mode session for you."

There is no "fire icon" in my toolbar in private browsing windows. I have tried resetting my toolbar to defaults, but that didn't help. I re-installed Firefox 151.0, but that didn't help. I re-booted my system, but that didn't help. I have run out of ideas.

Can anyone tell me how to get this button to appear in the toolbar in private browsing sessions?

I'm using Windows 11 25H2 on a Dell XPS 9630 tower computer.

Thanks, Bill

If i want Firefox browser to download the xpi file and save it locally when I click on the download link button for the xpi file, instead of installing it as an add-on. What should I do?

I have custom userChrome file that made my history and hamburger menu (application menu / settings) text and distances smaller since Firefox introduced this ugly feature, trying to be cool in windows 10 times. Nowadays even windows 11 brings back compact mode but firefox still uses huge spacing. I just fixed issue with custom CSS and forgot about it. Unfortunately, after updating to FF 151, my CSS is ignored and I am forced to new ugly context menu. What is weird, I still have good small pacing when right-clicking pages, UI elements and when I enter bookmarks. Only places that ignore my CSS are hamburger menu for settings and list under history view. I do not really understand this code, I just copied it from someone else. Can someone help me fix this issue?

I see "Look for the VPN setup prompt in the top-right corner of your Firefox toolbar. If you don't see it, click the VPN icon in the toolbar." I don't see a setup prompt, and I don't see a VPN icon. What does it look like? Where should it be?

Another message says I can modify the toolbar to add the icon, but I see no icon for VPN.

Windows 11, Firefox 151.0.

in the last week or so anytime I click on a page a new tab will open with junk ads or a popup will come up on the screen and block content. They can be closed and deleted but it happens continually no matter what settings I have or preferences set. I have pop up blocker toggled in the settings and I have a Mozilla ad blocker but it is not working. Please help! this is really annoying!

For 24 hours now I have not been able to connect to Facebook via Firefox browser on my laptop at all. I can connect on my phone, but not my laptop. I've made sure there are no extensions on my browser, my firewall is off, all cookies and cache have been cleared, I even Uninstaller Firefox and reinstalled it. When I try to bring up Facebook, nothing happens. It won't even bring the page up. All other websites work fine. I can't even bring up Facebook to clear the caches in Facebook per the troubleshooting guide. It says to open Dacwbook and click the lock on the address bar, but I can't even open Facebook. What am I missing here?

After the resent update i had yesterday 19/05/2026 my icons section and the icon have all become smaller, i had studies on and i remove that, and it did not help. It have happened the last year now that every second or third update my shortcuts icon and the space around em get smaller and smaller, now the text under icons are all broken up, a year ago it lined up perfectly and readable with the right place for new lines.

I got so much space on my start page and it keep use less and less, is there a way to undo this smaller size.

Using Windows 11 and got display setting 2560 x 1440, which is not small but no near big neither in today.
