Firefox Support Forum

Hello, so I am not very experienced and recently discovered how to customize Fire Fox using the userChrome.css file. I went through all of the steps that are required in order to do this. I set up a folder called chrome in the directory /Users/my name/Library/Application Support/Firefox/Profiles/x1oheo82.default-release To test if it works I wrote this into the userChrome.css file: @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* set default namespace to XUL */

1. TabsToolbar{ background-color: #FF0000 !important }

and set toolkit.legacyUserProfileCustomizations.stylesheets to true After restarting Fire Fox I saw that nothing changed. I double checked if there was a hidden file extension or if I might be in the wrong directory. I tried different code to see if there was some error in the code but nothing changed. I watched countless tutorials on You Tube and tried to find answers on google but nothing that I did seemed to help. I don't know if it has something to do with the operating system I am running or if it is a limitation of my computer hardware (I am running Fire Fox on an m1 mac).

The Firefox desktop browser default font is replacing all fonts on some websites, only title fonts on some others, and then leaving others unchanged. It seems random, and I can't stop the default font from taking over randomly on most websites no matter what I do. This was not happening until today, and no browsers or general MacBook Air preferences were changed between today and yesterday when I last used the browser on desktop.

Under Firefox Preferences » Fonts » Advanced, I've made sure to check the box to "Allow pages to choose their own fonts instead of your selections above", and I've unchecked it, and I've re-checked it, and the default is still overriding fonts on most websites.

I've quit and restarted Firefox 3 times.

Help!

When I'm using my Firefox browser and signing in to my Gmail account, the autofill function always gives me several old, expired gmail account names that I don't wish to see anymore. It's very annoying. I think I have turned off all the autofill options under Firefox>Preferences, but all these old account names keep showing up. Any suggestions for how to solve this? Thank you

1) Firefox advertised free apps when you signed up for vpn. However, when I signed up for vpn, I didn't get any apps. Did I do something wrong? Why didn't I get the free apps? 2) I don't seem to be able to add the VPN two other computers. It seems to want to sell me (Again) the VPN. I don't want to buy it again, just add my existing VPN to other computers. 3) I have some Macs that run Parallel's. Do I need to add Firefox VPN do the Windows that is running on Mac. Or, does my Mac Firefox VPN somehow protect the windows without adding a separate VPN on windows?

Every time I go to Fox News, the video at the top of the page drops to the lower right-hand corner. It's an annoyance I've been searching for a way to eliminate. I have pop-ups blocked in preferences and I have a couple of different pop-up blockers, but nothing seems to work. I'm currently using Firefox 114b.09 on a Mac Desktop.

Hello,

Whenever I use Firefox, I end up seeing popups (necessary for school) and would like to show them as tabs so I can merge them into other windows. I have tried the solutions given in: https://support.mozilla.org/en-US/questions/1080255 and nothing seemed to work. Is there another way to make sure that popup windows cannot hide the toolbar and show tabs?

I have a tracking app on macOS Monterey that is following me around

On Firefox settings I came cross some locations where I see Google Chrome like on page info about:home or Application Basics: Google Location Service Key and Google Safe browning Key. Also, on a link called Survey where there is Google forms to fill out. I don't use Google Chrome because of the issues Google Chrome creates when I go on my the websites. Why are these Google things in Firefox and is there a way to remove them?

When entering a local domain in the URL bar Firefox sends the request to a search engine instead of the DNS server. How can I stop this behaviour and switch back to how it was before?

Hi! I recently made the switch from Chrome to Firefox and Im liking it aside from this one thing. When Im watching a video in full screen, moving the cursor to the top doesnt pop up Macs top bar (File, Edit, ..... battery, time).

This sounds like a banality but I mainly watch videos while getting ready, working etc, and I really need to see the time! Im used to always keeping the cursor at the top to see it. I searched around in settings and forums but didnt find any fix. The only solution seems to be to not use full screen which I think we can all agree just sucks in a major way.

Im using MacOS Monterey 12.3.1 and Firefox 102.0.1. Is there a way to fix this or nah? Any info much appreciated!

I can't enable USB Devices on about:debugging setup page. I already installed ADB toolkit for MacOS, also I can see my device in ADB devices list: ``` ~% adb devices -l List of devices attached 013db356 device usb:336723968X product:OnePlus6T model:ONEPLUS_A6010 device:OnePlus6T transport_id:9 ```

On the device I've enabled "Remote debugging via USB". But when I click on "Enable USB Devices" button, nothing happens. I can see only "Updating..." message, then "Disabled" again.

Also no devices in the devices list, because USB Devices are disabled. "Refresh devices" does not make any changes.

My browser displays many websites, emails, etc. using a strange garbled font (see attached image for reference).

I already checked the preference setting for allowing websites to select their own fonts. The issue also persists in Troubleshooting mode. I have also used the "Inspect element" tool when this has occurred, also to no avail. I imagine at this point the only real solution is to delete and reinstall Firefox, but I'd love to hear if someone has another solution! Thanks!

Note that text in bold / italics often shows up just fine. I can also copy-paste any of this text and it displays correctly.

With the upgrade to Firefox 106 on Mac, Private browsing windows open with a dark theme by default. How do I enable the light theme for Private browsing windows?

I use Private browsing at work for website testing, and the dark themed tabs / UI are much harder to read and use than with a light theme.

Help? I rebooted my machine and lost all my open tabs. any attempt to re-acquire them shows just the ones I have open now. It doesn't show any of the ones that were lost. Thanks Monica

I've been watching and following along with a Unreal Engine 4 Course on Youtube for some time now (mentioning in case the resource usage has something to do with it), and in the past couple days I've noticed a pretty serious and annoying bug. When I pause the video, tab (Cmd + Tab on MacOS) into Unreal Engine, do some things, then tab back and resume the video, it will play for one frame and then stop and buffer, but the audio will continue playing. The only way to get the video to resume is to skip forward/backward in the video (either with the arrow keys or the progress bar). I've also tried Troubleshooting/Safe mode and the issue still persits.

When I use a vpn with firefox (not the firefox vpn), I cannot open normally blocked websites such as twitter or youtube, and instead they open in a sort of half-loaded state (see image). I don't face this problem with other browsers. I have tried deleting and reinstalling firefox, but it doesn't seem to work. Can anyone help out?

When I go into fullscreen on firefox macos, hovering near the top shows the traffic lights (fullscreen, minimize, close window buttons) and moves everything down. This may be expected behavior, but it is very annoying as when you try to open new tabs the tab bar moves out of the way of the traffic lights, and the traffic lights area is around the size of the tab bar. Is there any way to make the traffic lights always visible or keep them from moving?
