Firefox 社群討論區

Hello, I have my Apple settings set to dark mode at night time. I noticed even with Firefox having system selected for website appearance, it still does light mode at night. I attached a screenshot showing the discrepancy. Can you please get this fixed!

The firefox screen has shifted so that only two of my four lines of shortcuts appear on the screen. There is a larger than previous space between the ribbons at the top and the search bar that has appeared since I downloaded the newest firefox version. Before that, everything fit well on the screen.

I can't find the adjustment for my screen size. It's overrunning all the edges of my monitor making it impossible to see my panel on top and bottom. Is it in my computer or is it firefox?

After the most recent update, all of my Firefox tabs, bookmarks, and general UI fonts have gotten larger. Is this intended or a bug? There are not options that I know of to reduce the size of the fonts to how it looked previously either.

Hello.

My Firefox browser is missing the close button from the top bar. Minimize and Maximize buttons are present.

This is happening on Fedora 42 With Gnome.

I believe I don´t have any custom theme or user css or extension that could cause this.

Also because, it seems to be hapenning not only in Firefox itself, but also in Firefox based browsers, like Tor Browser.

Anyone has any idea what is hapenning?

Thank you.

During the week of March 7-13, 2026, upgrade(s) caused the size of my bookmarks, fonts and tabs to shrink to barely readable (see attachment) in the Firefox browser window on my Windows 11 PC. I've tried every internet base advice article. How do I increase the size of them?

The entire window of Firefox has an abnormally low resolution, makes the entire browser seems blurred. This issue occurs after I upgrade firefox to 146.0. I've attached a screenshot, and you can see the Firefox window has lower resolution than the wallpaper and task bar.

Hello,

Suddenly some UI elements became color-inverted or almost completely black, such as the tab icons in the tab bar, the website icons on the New Tab page and some icons in the settings menu. Also, some websites appear to have this issue, but the Samsung website is the only one I found so far with this issue.

On the same day it happened I switched to an OLED HDR-capable monitor, so I assumed it would be related to HDR, but I played around with some settings and I'm not sure anymore.

What I tried: - hardware acceleration on and off - HDR completely on and off - default light theme and dark theme, no customs themes installed - all extensions disabled (I have no extensions that would influence graphics or colors anyways) - latest update already installed - nothing else changed in the Nvidia control panel as far as I remember

None of the above helped. Any advice on this is appreciated. Attaching some pictures with the issue. Using Windows 11.

Thank you!

Hello,

I like how easily I can access bookmarks, tabs from other devices, and the chatbot from the "Tools" bar on the sidebar, but it becomes inaccessible after enabling "Expand sidebar on hover".

See images attached showing before and after enabling "on hover".

Am I missing something? Is there a workaround?

Thank you.

Latest update reduced the size of tiles on my new tab page. they're too small now to read the letter or custom image. And only a few letters of the name of the site below the tile are visible. Not enough to know what the tile is for.

How do I return them to their normal size?

popped up after an update, not only is it slightly distracting but also annoying as now when i try to pick up or select a tab by putting my mouse at the top of the screen it does nothing, as i select the useless black bar instead

How do I enable syntax highlighting when viewing the mark up of a web page, using the "view-source" functionality of the current tab.

It no longer works for me, I need to use this feature so I can find errors in my HTML markup.

Does the "view-source" feature have any optional settings available to the user and how do I find them using the about: option

TIA.
