Firefox Support Forum

I have tried disabling all system security (Talktalk F-Secure) on my desktop system but it does not solve the problem. The issue affects my smart phone, tablet and desktop when connecting via my TalkTalk router. However, the tablet, for example, connects via my work router. Any bright ideas anyone

I have rather abruptly lost all audio in Firefox 77 on Windows 10. YouTube, Netflix, Amazon Prime Video, Facebook videos - all silent.

Meanwhile, I'm getting sound as usual when viewing those things in Chrome (and I would really prefer not to have to go back to Chrome), and all sound from other sources is working correctly - games, iTunes, Spotify, etc.

Does Firefox hook into my system's audio functions in some unique way, different from everything else? I've recently started experimenting with doing my own music and video recording/editing, and I've tried out a number of different audio/video apps in an attempt to find the tools that suit me, and I'm starting to wonder if one of the apps I tried modified or overwrote whatever system hook that Firefox was using.

Strangely enough, the audio spontaneously started working again yesterday, a few hours after it stopped, and was still working today until I rebooted my machine. Then it was gone again.

When I am on a Firefox webpage and it site says something like "Click Here" to open a how to file or a pfd or a statement to print...those types of things. Once I click on the button Firefox starts to open new tabs, one after another. It never stops. I end up shutting down Firefox before it finishes. I counted 55 new tabs at one point. But, the new material never shows up either! Any suggestions?

I am not able to post pictures in Facebook comments using Firefox on my laptop. I am posting this here rather than in FB because I *am* able to post using Internet Explorer. When I click on the camera icon within the comment area nothing happens. In IE, doing the same opens up the ususal window to select the file I want to upload. Also, on my LG Android phone I can add photos to comments. Is there some setting in Firefox that could be the cause?

Ever since switching from Chrome to Firefox, I have been unable to log in to Tumblr. I have checked my phone like five times to make sure I am using the right password - I am. I can successfully log in to Tumblr on my phone, but not on Firefox. This is the only website I have this problem with - I have tried to contact their support, but I figured I would contact Firefox support too since I don't know which side is causing the problem.

Please let me know what I should do.

I have been a subscriber of Scroll for a while, and recently installed the Firefox Better Web extension to use Scroll in the Firefox browser. If I toggle reader view on Firefox, will websites still earn income from my Scroll subscription while the Firefox Better Web extension is active?

When visiting the above site in the latest version of Firefox Developer the page fails to render. However, when I view the page in Firefox (regular non-developer version) there are warnings regarding the site using an unsupported version of TLS. Here is the warning:

This site uses a deprecated version of TLS that will be disabled in March 2020. Please upgrade to TLS 1.2 or 1.3.

Will Firefox in the future drop support for TLS 1.1 and lower?

Just recently the BING home page overrides the Firefox home page on opening Firefox (default)? I don't know how to get rid of it. Bing is unclicked as an optional search engine; I only use Google.

New firefox 77.0.1 (64 bit) installation on Ubuntu 18.04 laptop. Synced with firefox sync. Bookmarks favicons are not refreshed. Screenshot attached. All of them show a globe until you click the favicon and load the link.

How to get all favicons refreshed in one go?

Thanks.

Previously cached web content would go to zero after I hit clear. Now it's been leaving 10 kb after I hit clear. Should I be worried? Is there a way to get it to go back to zero?

When hitting sign in the help page came up. I tries several times and the same thing happened - what to do, and shouldn't my FF browser be automatic when I click the icon - seems like it did before - have been sick and only at the computer sporadically - nothing seems to work as before....Hope you can help Thanks email: [email address]

Fields in fillable forms are invisible in Firefox. They are there, but text titles and where to type don't show. The fields are autofilling (for those fields where auto fill has been enabled), but the info can't be seen. It's impossible to tell where the fields are, or if they have have been filled in or if info needs to be entered. This happens with log in pages as well as pages requiring info for ordering and such.

These features are working in other browsers.

I have checked all settings and even uninstall ad-ons, it first started happened on my work computer. Thought it was the computer hardware or something. But now I got a laptop and it happened as well. I don't know what's causing the issue or how to fix it.

It's very frustrating because I can't really read well what it says now. I have attached a screenshot of the problem and it happens on almost every website

An important url link no longer works. The Icon I used was working for years. Is it possible it is blocked? I use the required link to login to my IRA and I get a blank screen with a note - Try Again. The link works in Private Browsing window. I can get it to work on my cell phone, Windows Explorer also.This link is very important to me. I have searched to no end to see if it was blocked. Is it safe to use Private Browser? I do not know how to setup Private Windows. What do I do to get the link working again from my Favorites bar?
