Firefox 社群討論區

On the screenshots you can see my wallpaper and desktop icons peeking through. This problem had started like a month ago and it was just a one time thing, after opening the browser and getting fullscreen the 2nd it never came back until restarting the browser. Now after the updated with rounded edges everywhere, going fullscreen is always misaligned

When i watch netflix,youtube and etc i cant go fully full screen. i see my desktop wallpaper a small bit on the side and top of my monitor. i only had problems with firefox this way. before i usually could just go out and in to full screen and it would fix but now i cant and its really iritating

Youtube does not work. It shows somekind of default page that is essentially blank. It does say: "Try searching to get started" and "Start watching videos to help us build a feed of videos you'll love."

But it will not respond when I attempt to search anything.

Firefox's new version was installed but after downloading and opening, when it opened, NONE of my tabs opened. I tried 6 times to no avail. I need my tabs. How do I fix this?

Today is 11-12-2025. After the last update a few days ago, many of my websites would not load up on firefox and when try on Edge or Chrome, they would work perfectly. I did a recovery back to 10-31-2025 and everything worked fine. Now I am afraid to do another update until I know what is going on. What would you suggest? Thanks,

I have my desktop extended across two displays. If I disable Hardware Acceleration in Firefox, entering fullscreen causes the window to be slightly offset down and right, leaving a thin band on the top and left sides of the screen where the desktop background and taskbar are visible behind the Firefox window.

From testing I have determined that this issue does not occur if I only have one monitor enabled or the monitors are mirroring the same display. I have also determined that the issue only occurs when Hardware Acceleration is disabled.

Since update to latest version of Firefox, I cannot access content on Facebook. All I get after long wait is the blank screen with the Facebook logo in the middle and Meta logo at the bottom. No problem before update. Other sites seem OK but take much longer to load. I can get Facebook with MS Edge. I'm using Windows 10 on PC.

Hi all,

I just updated from v143.0.3 to v145.0 and once again some small breakages in my userChrome.css have occurred.

Things have become too rounded, including tabs, the URL bar, and the chevron button.

I've solved the tabs radius issue with the .tab-background {} selector.

However, my URL bar now has rounded corners. I would like it to be square.

Please see the attached images for before & after views of my URL bar.

I have this code in place...

#urlbar > #urlbar-background, #urlbar[breakout][breakout-extend] > #urlbar-background, #searchbar
{ border: 1px solid #a1a6b5 !important; outline: none !important;   border-radius: 0px !important; }

I've also tried this as a standalone...

#urlbar-background {
  border-radius: 0px !important;
}

But the above has no effect, although it did previously.

Is there a new way to control the radius of the URL bar?

Also, my chevron button became too rounded. Is there a new way to control that as well?

Thanks.

Hi, Since the search open tabs function is part of the overflow button in a horizontal tab layout, when you switch to vertical tabs, you lose that search function. Is there a way to add it to my vertical tab layout? Thanks, Scott
