When you right-click on a window thumbnail, a menu should appear, but instead the window thumbnail just disappears. The screenshots show 1) a Firefox mini-window 2) a mini-window that just disappeared when you right-click 3) a mini-window of any other program 4) the menu that appeared is as it should be Otherwise the browser works absolutely fine for a long time. But this problem causes a lot of inconvenience because I have 2 monitors.

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.

Hi there! The New Tab page looks great with white text, but Firefox 140.0.4 thinks my wallpaper is white, so text should be dark. I can change the body class to "activity-stream darkWallpaper" using the inspector and it works fine, but how make this change permanently?

I recently upgraded from 128esr to 142, and one of the versions changed the tab mute button into a separate button.

How do I change it back to mute button on logo? if it isn't possible, can I remove the mute button

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.

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!

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?

On some websites, such as scratch.mit.edu, the fonts have been displaying as Burbank Big (a font i recently downloaded) instead of the regular font. This happens on other websites that don't use Helvetica Niue as well, so i'm stumped. I checked the styles panel in inspector and it showed the correct names, but when i hovered my cursor over it, it showed a preview of Burbank Big instead. What do i do to fix this?

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

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?

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.

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.

Since update to Firefox version 138.0.1, my last viewed side bar is never automatically displayed upon REOPENING Firefox. I must always > View > Re-select the desired sidebar choice >

How can I get this side bar to re-display automatically upon opening Firefox as it used to in previous versions?
