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?

Hello all,

Ever since an update to Firefox from a few weeks ago, I have been having issues with white backgrounds displaying incorrectly in Firefox. I have attached two identical images from the NYT homepage: the first is a screenshot from Chrome and the second is the same exact image but taken from Firefox.

I have also attached another screenshot taken in Firefox from REI.com. You'll see that it's not necessarily just a white background that is causing the weird blue color. It also happens in products images being displayed incorrectly.

I figured this might be a Firefox website appearance setting, but I have played around with it and selected many different permutations and I haven't been able to solve this issue. I have also tried refreshing Firefox, using Firefox in Safemode, disabling all of my plugins/themes, etc. and nothing was fixed.

I am pretty sure this isn't a system wide issue or a monitor issue because these websites are being displayed 100% correct in Chrome and Edge. This is only an issue in Firefox.

Can someone advise?


Thanks,

DC

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?

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!

I want my bookmarks toolbar to be across the top of the page but I can only find it from the 3 bars at the top right of the screen. When I click on it, I am given the option to hide the toolbar, but it's already hidden. I have also navigated from the View menu as well, and the toolbar is set on Always Show. I have run out of things to try. I am on a laptop with Microsoft Windows. Can someone offer assistance?

Hello, does Firefox has a function where the bookmarks only show in a Bookmarks toolbar when a blank tab is open please? Once a bookmark is selected from the Bookmarks Toolbar, then the Bookmarks Toolbar is no longer needed and should disappear to maximise webpage space.

Hi All,

I would like to hide the "New Tab to Right" option on the Tab Context Menu, and also remove the separator line right below that menu item.

The first line in the following code removes the Menu Item, but none of the 4 remaining lines succeed in removing the separator line. It remains at the top of the menu (see attached image).

Could anyone suggest some code to also remove the separator line at the top?

This is in FF 135.

Thank you.

#context_openANewTab,
#context_openANewTab + menuseparator,
#context_openANewTab_separator,
#context_reloadTab_separator,
#context_reloadTab + menuseparator::before {
   display: none !important;
}


This code below removes the first menu item and ALL separators from ALL menus, which is "ok" but not optimal.

menuseparator,
#context_openANewTab {
   display: none !important;
}


This solution provided by cor-el a few years ago appears to no longer work (the separator remains): https://support.mozilla.org/nl/questions/1340761

Hi everyone!

Since last update (136?) when I open a page with a video in a new tab, the width of this tab is very small! Almost half my current tab.

(I don't have another example but does this have anything to do with any "media" on a page?)

I have the width set to 152 for years...

When I play a video, the current tab is reduced. Pause= normal tab. Play= small tab. Pause= normal tab...

"browser.tabs.tabMinWidth should have been adhered to."

I just completely reinstalled Firefox: still the same.

What can I do, please?

The UI font on Firefox UI appears to be corrupted. See screenshots attached.

The app was installed recently and not used much. When I launched it today the font appears like this. No other apps are affected.

I only have a handful of custom fonts and none overwrite any system fonts.

I mean, the tabs size are already bothersome that if you have multiple tabs open it's annoying you can't read the title of the page on that tab. So, you change it manually to size 200 instead of fabricated install as 76.

Who makes sure to change these to different size?

Tab width size config browser.tabs.tabMinWidth

Now, on the latest version, it shrinks on multiple tabs.

WHO IS AUTHORIZING THE RELEASES? I MEAN, DO YOU INTENSIONALLY MAKE ERRORS AND RELEASE THEM?

I turned on my PC after a long time, and it seems something about firefox has changed in the way I don't like. The logo to the extreme left of the address bar which shows "This time search with" options on left-click is annoying to the eye. Picture attached below. Is there anyway you can remove/disable that logo with about://config or anything else.

I just noticed this today when my browser updated to 136.0.1 (64-bit).

In the Picture attached you can see the tab width changing when playing any audio that brings up whatever that audio symbol is officially called. This also happens when you mute a tab. When unmuting a tab or stopping audio the tab goes back to the regular size.

Is there any setting in the about:config that could stop the resizing of the tab or any setting at all to not have this happen?

Additional info: I have set browser.tabs.tabMinWidth to 140 in about:config. This setting has been this way for years and those tabs with the audio never resized until today.
