Firefox says I need a video codec to play a video (that is aparently somewhere on the page). It does NOT tell me what video, what video format, or what codec I need. How do I find out what codec I need?

Firefox version: 101.0 (64 bit) OS: Fedora 36

I have set the Noto family of fonts to be the default font family but websites that don't specify a font or specify sans-serif or monospace get Liberation Mono. When I changed any option in the fonts settings, the entire browser becomes Liberation Mono. I want Noto Sans be the default font for websites and for the Firefox UI. I tried to fix it by preforming a Firefox Refresh, but it didn't work. I think the problem began after upgrading to Firefox 100 but I'm no 100% sure.

Godaddy does not work at all on Firefox or in private. I had one add on and I disabled it. Godaddy still does not load Godaddy. Shall I simply remove Firefox and reinstall. I've spent 9 days now chasing this problem. Godaddy works fine with Chrome and Microsoft Edge. I no longer want the hassle of Godaddy issue.

What about:config option do I have to disable to remove those new buttons from the address bar?

Firefox 105.0b2

I suppose the other question is why did you add them? There are already three places I can get at that information.

Problem: Scrolling in firefox is feeling weird: instead of smooth scrolling with 2 fingers (like on smartphone with 1 finger) firefox scrolls only by steps only when I move my fingers enough to trigger scrolling. In other applications I can scroll smoothly and fully control scrolling, I can scroll exactly N pixels if I want. In firefox I can only move by N pixels per M cm fingers movement on touch pad.

It's feeling as indirect input. I can feel same feeling on Windows with simple mouse. Firefox scrolls slower than Opera.

How to reproduce and find difference with other applications:

1. Download Firefox and another application with direct input (Opera or Telegram for example)
2. Scroll Firefox
3. Scroll another application

Hi guys. So, I have Avira free antivirus. Can I still install for example Norton web security addon for Firefox? Will there be any problems between my installed antivirus and the Norton addon? Sorry if this is a noob question, but there you go :) Any help would be appriciated. Thanks in advance for any reply.

I haven't used my microphone in Firefox in years. I tried today, logged into Google Voice, which tells me it can't access the microphone. I set permissions in Firefox's settings. I turned up all the mic settings in alsamixer. I tried https://mdn.github.io/web-dictaphone/ , recommended in another thread here, and it doesn't record either. I can use the microphone outside X, with sox's rec. I also can't record a new greeting in Google Voice.

Firefox 100.0.2 , Linux, Slackware 64-bit, all packages updated this morning.

Hello Lovely Firefox Volunteers,

I hope this email finds you well. I am a long-time user and fan of Firefox, and other open source projects. Firefox is a fantastic internet browser!

Having said that, I was shocked and dismayed at what I encountered today. I was doing some tests for screen-reader usability on a website, and I came across the following:

Image 1 (attached): Advertisement of Screen-Reader Add-Ons for Firefox

Image 2 (attached): No Screen-Reader Add-Ons for Firefox are Available

The Firefox team is advertising screen-reader add-ons for Firefox, which don't seem to exist. I don't think the recommendation here should be: take down the advertisement for the Firefox native screen-reader add-ons/link to them, these seem to be really important for accessibility, and the Firefox team seems to acknowledge this. :)

There is some other missing piece - maybe there are Screen-reader add-ons for Firefox, and they aren't being linked to? Maybe the wrong tag is being used? (The auto tag that is used in the link is "screen reader"). Maybe there aren't any, and this is an area that needs some additional attention?

Anyway, I just thought I should bring this to your attention as making our internet accessible to people living with blindness and loss of sight is extremely important.

Sincerely, Katie

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!

I was using Ctrl+K on some websites to do things like site-specific search, task bars, and so forth, but recently Firefox started capturing it for focusing on the search/address bar (https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly#w_search).

Is there a way to unbind `Ctrl+K` in Firefox?

I appreciate the quick reply from your support staff yesterday. I followed instructions and was able to turn off the GIFs but FOR ONLY ONE TIME. As soon as I exited Firefox, or even the current page and returned to it they were back on. How do I keep them off permanently?

Is it possible to move the address bar above or below the Bookmarks Toolbar in Firefox 100.0 (64 bit). If not, can you provide a link to the latest version of Firefox for Mac OS X Catalina (10.15.7) that does not have the address bar on the same level as the Bookmarks Toolbar.

Many thanks.

I always use the current Firefox on two Macintosh browsers running OS 10.14.6.

Recently (in only one of the computers), if I download a file, a pane containing recent downloads opens in the upper left-hand quadrant. This is distinct from the downloads portion of the "Library" area, and gets in the way of my ability to use Firefox efficiently.

I can't seem to find a way to keep this pane from repeatedly opening up as I download things. Can anyone help?

I was attempting to reduce the size of the tab bar using about:config and I screwed up making everything so small I can't determine where the setting is to change it back. What can I do to get it back to normal, preferably without losing all my shortcuts?

Firefox stopped opening links in web pages like secondlife:///app/region/Kings%20Stone/224/155/22 ,WHere do I tell Firefox what application to use to handle that kind of a link?

So, for a few months now, the preview panel in Firefox has been popping up with every successful download of a file from online. Its a bit inconvenient because anytime it pops up, it basically tabs me off a page and interrupts my writing or the like. This wasn't an issue last year when after successful downloads, the downloads icon in the toolbar just lights up blue to signify a successful download. The preview panel popping up every time Firefox successfully downloads something (due to reasons, I download files in bulk from multiple sources) is incredibly irritating. The problem goes away when I just remove the download icon/panel from the toolbar entirely. I just wanna know WHY this bizarre phenomenon happens.
