When ever I start firefox, I receive two lines at the bottom of the home page - the first is a news feed (from Mozilla) and the second is a 'contributors' shout out. I've unchecked all the appropriate boxes in settings, and still no help. I've gone into about:config and ensured they are removed.

Any suggestions? Thanks in advance.

Youtube music on background and java-game playing(mahjong). After few hours, firefox crash after 'fetchmail' command on bash-terminal. This has happened now two times, both times opening another program induced crash. No messages in logs, it would seem like POP3 port access/ssl/something makes firefox just exit.

Firefox 99.0

I guess it's a problem with the latest update because it didn't happen to me before. Gmail keeps showing me this message: "Gmail is having authentication problems. Some features may not be operational. Please try logging in to troubleshoot the problem." I have relogin, deleted the cookies and site data but I still get that message. I have tried starting the browser from "about:support" in troubleshooting mode but the error still appears. This does not happen in other browsers.

When clicking on a link that does not include "www." in the URL, I am presented with an error SSL_ERROR_BAD_CERT_DOMAIN. But the certificate is good. the problem was the URL that did not include the "www."

This would be an easy fix! Just add "www." to the URL if it is missing. It could eliminate user confusion if they do not understand.

Just a suggestion

I've just started noticing in Firefox 99 on Arch Linux that Firefox is using the wrong font when the font-family is given as "ui-monospace/other fonts..., monospace". This looks similar to the issue mentioned here: https://support.mozilla.org/en-US/questions/1351497

The inspector for these websites underlines "monospace" as the active font, but then uses a non-monospace font (in my case, Bitstream Vera Sans) to display the content. This does not happen when the font-family is "monospace,monospace" or "monospace". I can't quite figure out exactly what causes the font to be chosen incorrectly: sometimes it does show up if I have the preceding fonts installed, e.g. Consolas or Liberation Mono, but other instances do not look as intended.

Currently, I have fontconfig set up such that: $ fc-match :family=ui-monospace VeraMono.ttf: "Bitstream Vera Sans Mono" "Roman" $ fc-match :family=monospace VeraMono.ttf: "Bitstream Vera Sans Mono" "Roman"

Firefox's fonts in about:preferences are configured as all defaults: Serif: Bitstream Vera Serif Sans: Bitstream Vera Sans Monospace: Bitstream Vera Sans Mono

I am trying to use the profiler. I have added the button as stated in https://profiler.firefox.com/, but when I hit Start Recording Firefox completely freezes and I have to quit it. My OS is Ubuntu 20.04. I have tried with version 91 in a virtual machine and it works fine. Have also tried with version 93 in a virtual machine with Fedora 35 and even though it lets me start recording, the moment I hit stop it freezes.

The issue concerns the Flatpak version of Firefox on Linux. This issue only happens when I'm connected to my VPN router. For info, I'm using Fedora 35 Silverblue. This issue happens on Fedora 35 or Fedora 35 Silverblue. I been using Fedora since version 33 and such problem existed back then.

When connected to my VPN provider via my router, trying to start a Firefox Flatpak instance takes minutes upon minutes to load. I'm guessing it has to do with DNS query's Firefox does on start but I'm not sure. All I know is that when I connect directly to the internet without being hehind my VPN, Firefox loads in a split second. When I'm using the RPM version of Firefox supplied by Fedora, I do not have such issues even when connected to my VPN. This issue only affects Firefox Flatpak when behind a VPN. I tried opening the AppImage version of Firefox while connected to my VPN, and once again, it loaded within a few seconds. I been having this issue for many years and only figured out recently that my VPN connection was causing a problem.

I would like to point out that the Flatpak verion of Microsoft Edge and Chromium do start without any issues even while I'm connected to my VPN provider...

I was following this article https://support.mozilla.org/en-US/kb/run-firefox-chromeos

Installed flatpak and repositories but when I try to use flatpak to install firefox I get "No remote refs found similar to ‘firefox’".

I have tried following a few other ways to get it installed, such as using sudo and using sudo su but that has not worked at all.

I followed to flatpak quick setup on Chromebook guide that is linked in the above help article and created the nested containers in crosh as well.

below is what happens if I go to flathub and copy-paste their recommended command to install firefox.

Remote ‘flathub’ found in multiple installations:

  1) system
  2) user

Which do you want to use (0 to abort)? [0-2]: 2 error: Nothing matches org.mozilla.firefox in remote flathub

Local Machine: Dell Inspiron i5-7200 / 16 GB RAM / Local Op Sys: Ubuntu 20.04LTS

Firefox version: 99.0 FFDE version: 100.0b5

Node.js version 14.18.1 npm version 6.14.15


I had a Node.js web app running on my local machine all usual browsers like Firefox, Firefox Dev Ed (FFDE), Chromium, Edge, Opera, etc till recently.

Recently it shows an error when run on Firefox (also on Chromium, Opera and Edge) although continuing to run okay on FFDE.

Firefox Error: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at file:///home/sandbar/Desktop/nodeapp-local/undefined. (Reason: CORS request not http).

Edge Error: Access to XMLHttpRequest at 'file:///home/sandbar/Desktop/nodeapp-local/undefined' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome-extension, edge, https, chrome-untrusted.


Naturally, I need to test the web app on my local machine using several browsers before I should upload it to a server and trial it there.

So how do I configure the browser and/or app to allow access to local machine files ?

Hello everyone :)

From a folder, I have loads of Firefox profiles from different eras. I am looking for a way to export all the bookmarks of each of the profiles to an HTML file like the manual method (Library > Import and backup > Export bookmarks to formal HTML), but all in an automatic way by script. I like the HTML export from Firefox because it allows you to quickly navigate using keywords, either in links or in the folder names I gave.

Is there a simple solution that would reuse, for example, the same export code as Firefox ?

I am running WikiSpecies on Ubuntu Firefox 64-bit v. 98.0.2.

I used to be able to display a collection of unused files with the used ones but showing a red color indicating that the file was unused (because noone had entered anything other than the file name).

Now, however, ALL files in a directory (e. g., see https://species.wikimedia.org/wiki/Craspedophorus) are shown with the same color, whether they include additional implementation details or not.

Would it be possible for you to restore the "unused" color of empty files? It is bothersome for me to open EVERY file, empty or not, in a directory just to find that most or all of them never have been implemented. Adding a special color -- or other distinctive display -- to unimplemented files would save me a great deal of time.

I am attaching a picture of a typical unimplemented file.
