All things I try to download on Firefox are extremely slow compared to other apps like Steam, torrents and other apps. I get 90mb/s on the download speed checks, but when I try to download something on Firefox, it downloads at like, 120 KB/s.

Hello,

I just upgraded to Firefox 87 and noticed that I wasn't able to go back to the previous webpage by clicking on the backspace button like what I have done in the past if I'm not using a mouse on my laptop and had to click on the back button in the toolbar with the trackpad. I'm not too sure of why that happened with the upgrade and was a little surprised about that. Hope I can be able to get around this in some way if one of you know anything about this. Thanks.

How can I change the DNS Server in FireFox to whatever DNS I want and not what Mozilla wants?

For example: Google DNS 8.8.8.8, 8.8.4.4 or, Open DNS 208.67.222.222 · 208.67.220.220

Enabling DNS over HTTPS dose not give me FULL control over this. I should be able to put a DNS IP address in there like in Internet Explore.

I am running "Firefox Browser 93.0", and I have Windows 10 Pro Version 21H1, OS Build 19043.1288. I am unable to watch certain video's, as an example, the video in this link: [https://www.wandtv.com/news/illinois-.../article_24b92a86-32c4-11ec-a487-3bb3f17fa133.html] won't play. It use to work, but something has changed, not by me. It will play that same video using the "Edge Browser" so there is nothing wrong with the website. However, I can play this "YouTube Video": [https://www.youtube.com/watch?v=qAJSYk5wMiA] I also tried another link in their website, this is the weather link: [https://www.wandtv.com/weather] it starts to play, but then stops and nothing ever plays. Here is another link I tried on their website: [https://www.wandtv.com/sports/fans-ma.../article_f94f4ade-32e0-11ec-9351-ef71f52b96cd.html] It won't play either. But they all play in the "Edge Browser!" Any ideas on what changed and how do I change it back, so they will play? I prefer Firefox Browser to any other browser! Do you know what the issue could be? I appreciate your time! NiceSeeingYou

Gmail is going to require OAuth 2.0 sign-in SFAIK, that means I will no longer be able to access gmail with Thunderbird. Are there plans for Thunderbird to meet the OAuth 2.0 requirement?

Heyo,

       I switched to firefox today and I noticed that on youtube there's an animation (fade in and out) when fullscreening. Is there any way to disable this?

Thanks

You can retry or save the message locally to Local Folders/Sent It is a problem occurring only with our company's mail provider. The thing is it work just fine know it seems i can't even get any messages.

This is kind of urgent because i cannot work like this.

Please if you could help with any suggestions. Thanks a lot.

Hello, I have trouble getting sound playback on firefox (checked 85.0 and 78.7.0esr both 64 bit) on windows 10. I checked sound on youtube, and netflix. I checked other applications like spotify and mpv, and soundplayback there is fine. Also it works on Firefox nightly (87.0a1).

What i have already tried: - restarting my computer - opening windows volume mixer and see if firefox is muted - updating my audio driver - different playback devices (Device over HDMI and Line out) - reinstalling firefox - uninstalling firefox, delete folders in C:\Users\$username\AppData\Local C:\Users\$username\AppData\Roaming - new install with fresh downloaded installer - restart to safe mode

Since firefox nightly is working i suspect that maybe the application name "Firefox" is muted somewhere. This could explain why i can reproduce my error on ESR and stable but not on nightly.

Thank you for your help in advance

Hi Firefox start to take a lot of CPU depending on how many tabs are opened (that is normal of course especially if with flash contents). What is not normal is that CPU will not be released when tabs are being closed, even with one (blank) tab left opened CPU usage is 40%-85% (depending if other process need CPU). Essentially: once Firefox process obtained 80% of CPU you can close tabs but you are fucked the same, now opening new tabs is a pain! Of course restart fix the issue. Is not a matter of addons or updates, Firefox and system (Windows 10) are updated to last version; I feel is something related with flash contents. Is it possible only me experience this?! Regards

Gmail will not load in Firefox, but will in Chrome. I've cleared my history, cookies, and cache. I made sure I had the latest Firefox update, restarted my computer, checked in internet connection, everything I could think of. There is no error message; it just stops loading and the page is totally blank, as you can see on the attached image. I've run out of ideas and know-how. Anyone else had this issue and resolved it?

Ever since the last update, every time I download something on Firefox this download tab pops up every time when the new download is complete. Ive tried disabling every extension, Ive tried the about:config solution I found on this page, setting it to "false" and I havent been able to find anything in tools or settings.. but nothing disables it and its getting annoying. Ive had Firefox for years and this has never happened before.

In my browser whenever I am opening non secure sites that are only like http://example.com it redirects to https://example.com and display the error. "Warning: Potential Security Risk Ahead" error. I could not know how to fix this error. This is happening all of a sudden. I could not find a way to fix this error.

I'm trying to take off this "Extension (Tabliss)" tag on my url. I have followed the instructions down below from another Firefox support forum: https://discourse.mozilla.org/t/make-addressbar-text-extension-name-of-the-extension-shorter-or-hide/28026/3

The instructions I followed are listed below:

"Users can apply custom style rules to modify Firefox’s toolbar area by creating a userChrome.css file. This takes about 10 minutes so when you have time to take it slowly and carefully:

(1) Set up your chrome folder and userChrome.css file following the five six steps in this article:

https://www.userchrome.org/how-create-userchrome-css.html 45

I have a boring video there if you like demonstrations.

(2) This is the code to paste into the file. You can edit the file using Notepad or a better editor. Make sure to keep it in a plain text format with a .css file extension (not .css.txt).

See improved rule down in: Make addressbar text "Extension (Name Of The Extension)" shorter or hide

/*

  Hide Extension Name in the identity area unless
  hovered for half a second (updated for Fx80)

• /

1. identity-box.extensionPage #identity-icon-labels,
2. identity-box.extensionPage #identity-icon-label {

 visibility: collapse !important;
 transition: visibility 250ms ease-in-out;

}

1. identity-box.extensionPage:hover #identity-icon-labels,
2. identity-box.extensionPage:hover #identity-icon-label {

 visibility: visible !important;
 transition: visibility 250ms ease-in-out 500ms;

}

(3) Firefox should read the file at its next startup and apply it to every extension page you load."

Edit: So, yeah, I need help getting this tag off. I'm new to Firefox so it could be something obvious I'm missing. I have also tried CTRL+SHIFT+R to reload the page for changes and also closed and reopened my Firefox entirely.

Thanks in advance.

Some of well known sites such as "drive.google.com" & "mail.yahoo.com" is resulting in "Did Not Connect: Potential Security Issue page" in Firefox. They are opening just fine in other browsers.

This issue has cropped up since past week in Firefox. Not sure what is the root cause behind the problem. I have tried re-installing Firefox, but still no change.

I have checked the certificates of those sites, and they are seems to be in order. I mean other browsers are able to open without issue, then why Firefox is not opening them for me?

Please let me know if this issue can be fixed in Firefox.

Hi, how can I open a local html file with firefox 86 on android 9? It's like firefox no longer registers itself as a valid program/association to open html files.

What I've tried so far: 1) If I type file:/// in the URL bar, nothing happens. It works on Opera. 2) If I go to a file manager, select an html file, and click "Open with", firefox doesn't show up; Chrome and Opera do. 3) If I go to the android settings > applications > firefox > associations, firefox shows no associated file types at all.

The HTML language isn't only used on the Internet, it's also used for local documents, please allow us to use firefox to view our local html files.

Good afternoon folks I can't watch Netflix on my Firefox browser. Do you know why is there a plug-in what is missing or something? He says the version is not up to date While my Firefox is always up to date, can you help me further. Thanks in advance from Trimmy.

Hello. I need help with: `DOMException: The quota has been exceeded.` I'm trying to use IndexedDB. However, the code is requesting persistent storage: `await window.navigator.storage.persist();` (and this is returning true) This website is only storing about 8MB of data and I have a different website storing 200MB of data (userscript) The storage medium still has 140GB available. What quota did I exceed? If this is the wrong place, please direct me to the right place

Hi! I found a strange thing today. I wanted to open an ftp link and firefox asked me in which app I wanted to open it. Of course I wanted to open it in Firefox, but the only app on list was Internet Explorer. So, I added Firefox to the list, but I couldn't open the link with it, because when I marked Firefox and tried to click "open", nothing happend and the box still appeared. So, I ended up using IE. I'm using Firefox Nightly (81.0a1 atm of encountering this).
