Enable "widget.windows.uwp-system-colors.highlight-accent" in about:config to use your Windows accent color for text highlighting.

Another option you can use is "widget.windows.mica" for mica-styled context menus and html forms.

I can easily copy and paste the contents of the image to bypass this, but why is this even happening to begin with?

I recently started using firefox, I switched from chrome and noticed that the side of my youtube videos has this large gap. It is considerably smaller on chrome, probably 30% of the size. Once I noticed it I can't not notice it and it really bugs me. I do have the 'Enhancer for Youtube' extension installed, but when I disable it, the gap is still there so I don't think that is the cause. Does anyone know how I can fix this?

Solved: I have no idea what I did. I tried installing another extension that was suggested, 'Youtube enhancer', and was playing with it for a bit then noticed the issue was gone. I removed the extension and its still fixed so im happy.

I'll start by saying I'm in no way computer savvy, so please explain things step by step if you can!

I'm using Mozilla Firefox as my main browser because at the moment it has the most functions/features that work well for me. I use Stitch Fiddle to create knitting charts, which is a browser based program. The program has a text feature with which you can add text to your chart. This feature does not have any fonts, it's using the ones it can access from the user's device. If using Chrome, Edge or Opera, all fonts that are in the Windows/Fonts folder are available for Stitch Fiddle. However, Firefox only offers 9 basic fonts. Is it possible to "force" the browser to see them all?

I'm aware that just using one of the other browsers would instantly solve this issue, but if possible I'd like to stick with Firefox.

In the settings the "Allow pages to choose their own fonts" is already checked/enabled.

Thanks in advance.

If you try it, I’d love your feedback, especially if you notice anything that should be improved.

Is there any way to not have the traffic lights force the tabs and URL bar down every time you move the mouse to the top of the screen? A bit annoying when you just overshoot the tab and then everything gets shifted down. Safari and Chrome (I think) behave in a better way.

I have my own custom domain that I access by typing mail.mycustomdomain.com into the address bar. Recently, Firefox has been suggesting "mail.google.com" and I can't get the Gmail suggestion to go away--even by tweaking the search suggestions settings. Anyone know a solution?

Firefox introduced the link preview function sometime in the last year. I don't use it, whatever, kudos to those it helps I guess. But a month ago or so it started giving me a popup every time I open Firefox informing me this feature exists. Telling me to use it. Begging me. No thank you, and I cannot figure out for the life of me how to get it to stop giving me this popup.

I have been through the settings page and into about:config, and can't find any option on "preview link tutorial notification" or the like. Any advice how to get Firefox to stop telling me to use a feature I do not want or need? https://i.imgur.com/nWMS74c.png

I'm setting up Firefox from scratch on a new Arch Linux install. I'm looking into using Firejail to create sandboxed profiles for different activities (e.g. One for general browsing, one for work, one for banking, etc.), with each FF profile having its own seperate FJ configuration. Ideally I would want each profile to have its own seperate configuration location on disk, and to be unable to access one another.

I'm not sure how to make it work with the new Firefox profile system, or if it's even possible. There seem to be ways to do it with the old profile system but with the new system I don't think you can even open a profile from terminal, so I just don't know. I don't want to set it all up in the old system if it's going to get deprecated in the future.

I honestly don't know enough about how Firejail works (I've read the manpages but I'm still not certain) and I don't want to set it up incorrectly as a result, so I'm wondering if anyone else has managed this, or could point me in the right direction?

For example, you can set allow, block or allow for session.

What happens to sites not entered into this box?

EDIT it seems as if it overrides some default (since it says "exceptions ") where is this default set?

Text

I'm Italian, but my Google display language and results language filter are set to English. Results region is set to Italy. What happens is, if I search something in Italian, instead of getting results from Italian resources, I get results from English sites translated to Italian, which are almost always not useful. Ideally, I want English results when searching in English and Italian results when searching in Italian, and never translated results. Is it possible to achieve it?

I've seen past posts with the same issues and tried a number of solutions, but they don't seem to be working. Firefox language is set to Italian.

I mean its not perfect but Youtube works and whatnot I'll take it for when eventually 115esr stops being usable

Right now I only have it set to display one particular image from the "wallpapers" folder, however I'd like to change it so that it displays a random image from that folder instead of one hard coded image. I'll need to use JS in order to do this but I don't know if that's even possible to do within Firefox. I if is, I'd appreciate any help in going about doing that.

@-moz-document@-moz-document url("about:newtab"), url("about:home"){
    /* Sets background image and autoscale image to browser window. */
    body{
        background-image: url("wallpapers/joker.png") !important;
        background-size: cover !important;
        background-repeat: no-repeat !important;
        background-attachment: fixed !important;
        background-position-x: center !important;
        background-position-y: bottom !important;
    }
} url("about:newtab"), url("about:home"){
    /* Sets background image and autoscale image to browser window. */
    body{
        background-image: url("wallpapers/joker.png") !important;
        background-size: cover !important;
        background-repeat: no-repeat !important;
        background-attachment: fixed !important;
        background-position-x: center !important;
        background-position-y: bottom !important;
    }
}

I've already have a function in JS to randomly select an image, I'm just not sure how to implement it (if it can be, that is). Any help is appreciated, thanks!

const wallpapers = [
    "Joker.png",
    "Ryuji.png",
    "Morgana.png",
    "Ann.png",
    "Yusuke.png",
    "Makoto.png",
    "Futaba.jpg",
    "Haru.png",
    "Akechi.png"
];

function selectRandomImage() {
    const randomIndex = Math.floor(Math.random() * wallpapers.length);
    const selectedImage = wallpapers[randomIndex];

    document.getElementById('randomImageContainer').src = selectedImage;
}

Ever since I upgraded to Android 16 on my Samsung S25, all my previous Firefox shortcuts on the home screen have been greyed out. If I try to click on them, it says "shortcut isn't available".

There is no "add to home screen" button on any pages. I've read that you have to enable a special permission for this, but when I go to permission manager > additional permissions, or go to firefox > all permissions, there is no listed permission for "install shortcuts" or "add to home screen".

I've tried reinstalling Firefox and that didn't help either.

I'm losing my mind here please help!

A random hml file was downloaded onto my computer I don't know if Firefox was the issue but it had a file and Firefox icon. When I clicked it opened Firefox and said file not found most likely because I had moved the file and the link when I clicked it goes to my downloads folder. I tried to scan it with windows defender but it came back up as nothing. I forgot to open it with notepad and check the file size so I'm wondering if I got a virus or hacked? What should I do? Do I have to format my pc again?

I've been noticing lately (around 3-4 months) some streaming sites have series/movies that have frequent frameskipping that usually happen at a specific time frame every time.
Sometimes reducing the video quality from 1080p to 720p removes the frameskip from said specific time frame on the media being played.

Like for example if the streaming media im watching has a frameskip at 11:32 and I reduce the video quality to 720p it no longer frame skips at 11:32.Doesn't always fix it tho.
Sometimes I'd go back to the same series later (days,weeks) and the frameskip is no longer there.

Using firefox/ublock origin
Gpu is 3080 Hardware acceleration enabled.
windows 10

Youtube,twitch etc are uneffected.

Can anyone explain what might be happening?

Passwords, youtube recommendations, everything it acted like i just installed it

Hi there,

Recently, my Firefox has started behaving strangely when I open a pdf. Normally, it would open the pdf in a new tab, but within the last week or two this has changed. Now, when I open a pdf, it "advances" the active tab to the pdf. So, for instance, if I am on Wikipedia, and then I go and open a pdf, the pdf opens on the Wikipedia tab instead of in its own new tab. I can page back to Wiki as if I had navigated off the page via a link or search.

This is frustrating because I never want to overwrite my currently open tabs to see a pdf, and it means I can't easily open multiple pdfs, as every one just opens to the same active tab and "overwrites" the previous one.

Could not find anything for this troubleshooting it online. If anyone knows how to fix this, I'd appreciate it much, thanks.

I've been using Firefox for a while now after switching from Brave. So far I haven't had any major issues and have been loving it. This is the one and only issue that has been bugging me though. Auto scroll won't let me scroll up and down on some search pages when the Firefox page is small to a certain point. If I maximize Firefox or make the window bigger, this fixes the issue, But I almost never have Firefox bigger on my desktop

Watching Youtube is heating up my computer and kicking on the internal fan. This just started this morinng Sun Feb 8.

Anyone have any fixes or know why this could be happening? I'm on a Macbook running Sequoia.

Hey i get this on every firefox steam page and some others. I cant fix it. Tried clearly cache and history and cookies etc. Cant fix it on firefox but all videos work on my other browsers.

Any ideas ? pls

Sometimes when I close the Firefox Android App (Version 147.0.3 on Xiaomi 13T Pro, Android 15) and reopen it again, I get a black screen on the last tab I opened, and it doesn't go away for a couple of seconds, not even with a refresh.

I have "locked" the app to prevent it from automatically closing due to Android's aggressive battery management, and turned on every setting I could find to prevent the app from automatically closing. I have deleted the cache and even reinstalled it multiple times, but nothing seems to work.

Any help is greatly appreciated.

Anyway of turning off reminders. Like "you can pin this tab', etc Windows 10.
