ff 81.0b5, last updated 03 sep 20. problem: after 9 reliable years, Canon ImageClass MF3240 printer suddenly started printing ALL blank pages when printing from FF. printer knows how many pages to print, just they are all blank. printer runs *normally* off Tbird, Notepad, Adobe Acrobat, etc., and also from another browser (Opera). yesterday i noticed for the first time that when i call for a print of a web page (FF), i get a really weird looking Print Preview page that i have never seen before. after choosing which pages i want to print (Custom), i click print and it spends a long time sending the print job to printer. then i get all blank pages. sometimes the Preview page on the display goes blank, too. sometimes i get a popup error message 'there was an error in printing' OWTTE. the directions in FF Help for printing are obviously written for the Print preview Page i WAS seeing before yesterday 03 Sep 20. they do NOT reflect the choices shown on the new, strange-looking Print Preview.

what i'v done so far re-start FF re-start FF in Safe re-start computer read Troubleshooting Info in about:support https://support.mozilla.org/en-US/kb/fix-printing-problems-firefox -completed steps 1-9 "reset FF printer setting" completed steps 1-4 haven't yet had the nerve to "Reset ALL FF printer settings" (too scared to mess with the prefs.js file, so far)


any ideas? thanks

The world is not-so-slowly getting undermined by sophisticated technical attacks on our understanding of reality (pretty much any topic - take politics as an example). One of the newer technology is the ability to create, through sophisticated digital editing tools that utilize artificial intelligence, videos that simulate public figures doing or saying whatever the author wishes. There are DeepFake pornographic movies with popular actors and politicians. They run the gamut of ones imagination. Without specific tools to detect and block such products, we're all just sitting ducks in a rising tide of disinformation.

I would like to see a tool embedded in Firefox that detects and notifies the user/viewer of deepfake graphics: photo or video images.

There are of course issues. Performance is certainly one. This might be mitigated by having images buffered in the cloud where they could be analyzed with high performance hardware - then they could be downloaded to our smartphones and other devices. People with high end hardware could do this locally as an option.

I could go on, but I think I've summarized the need.

Here's a tool that Microsoft just released: https://techcrunch.com/2020/09/02/microsoft-launches-a-deepfake-detector-tool-ahead-of-us-election/

So, I have been looking for lots of solutions but none of them worked. I'm using Ubuntu 20.04 and want to install and update Firefox Dev automatically. I tried some ways:

  • By package manager:

First, I uninstalled the default Firefox, removed its ppa repo then added Firefox Dev ppa and installed. Opened up and it was still normal Firefox.

  • By downloading .deb file from Mozilla:

I could install by this way but every time has an update, Firefox will notify me "Firefox can't udpate to the latest version. Download a fresh copy of Firefox". I also have Chrome to be installed via .deb, it can update automatically. Why Firefox can't? It's very annoying that every time I open Firefox, it pops the notification up. It's impossible that every time Firefox has an update (which occurs regularly!) I have to go to homepage, download then install it manually. I can write a script to update Firefox but I want an official support from Mozilla.

Firefox Lockwise passwords (no reason at all) just disappears in the browser more often now and randomly. I have wasted countless hours researching possible solution via mozilla support and the Internet. The only ways I can recover them to my browser is from my Firefox Android. However. I must log out of sync in both PC & Android browser then sign back in. Tired of doing this. Now. Even more recently. Most my websites I sign into now does not work. The ID and password is correct but when I click sign in. Nothing happens. This newer problem is spreading to more and more my regular sites.. Do not bother to answer. I have used Firefox from the begining. I see the writing on the wall. Am now using EDGE. So far, so good.

I am on Firefox Dev edition 81. When navigating a plain HTML form with the keyboard, the spacebar does not check radio or checkbox inputs.

This is the page I'm using for testing: http://fyvr.net/a11y/spacebar-action.html

When I test the same page in Firefox 80, the spacebar behaves as expected.

Appreciate any help!

I decided to use Firefox Developer Edition on my Linux machine (Fedora 32) as I migrate from Windows for Web Development, but I have hit a wall with it with Gnome Extensions. I get the following error when I attempt to modify or even view extensions.gnome.org content:

Although GNOME Shell integration extension is running, native host connector is not detected. Refer documentation for instructions about installing connector.

The only resolve I found for this is Chrome-based so I do not feel that is the issue I am having. The browser works fine other than this, at least from what I can tell. Is there a way to use the extensions? Should this issue be a precursor to things on Fedora that should keep me on Windows for the browser? Please advise, I want to make the full move to Linux soon.

on a Google meeting, that is, a meeting created in Google Calendar that generates those automated Google meeting URLs:

when I share my screen, I also want my mouse cursor to be shared, because it's very useful to use it as a laser pointer so the audience in the meeting knows which part of the screen they should be looking at.

I couldn't find any feature at all within Firefox or inside the Google meeting settings [as the meeting is happening] to turn on my mouse cursor sharing.

On Chrome the mouse cursor is shared by default when someone shares their screen, which is desired behaviour.

It's a local problem with Firefox because other co-workers who have identical computers to mine use Chrome and I always see their mouse cursor when they share their screens. I'm on Windows 10.

It was about last week (14-Sep-2020) that Google started rolling out the feature to blur the background in the webcam's image. Only the person is not blurred.

This feature is appearing on Chrome, but not on Firefox.

Is this something that Firefox has the control over to turn on? Or it this outside of Firefox's controlled and controlled by Google?

Completo la pregunta anterior. He intentado, por un lado, recuperar los marcadores del perfil y me ha sido imposible. Importarlos de Chrome también me ayudaría, pero me ha resultado imposible. Sigo los procesos indicados por ustedes, a través de Catálogo, llego al final del proceso, doy a "Finalizar", pero nada sucede. Indudablemente, Chrome estaba cerrado.

Could not go through process of changing my password for a bank website, called bank, it was suggested to clear my history and cache in Firefox, I did so. This allowed the automated process of changing my password to process through ok. I could then not sign in to that website or another site with firefox. either auto sign in or manually entering my credentials. I can sign in to all my websites in MS Edge. Not in firefox. I have cleared my cache and the "Corrupt cache" file. also checked the error log and it is not being caused by a security certificate issue. Can anyone assist me? I would appreciate any help. It is not critical as I can sign in through a different browser and it is only happening on a couple websites but it is annoying. Thanks Art

Hi all,

MacBook Pro (16-inch, 2019) macOS Big Sur - 20A5374i Firefox 82.0b3

This is a rather weird one to try and explain.

Ever since macOS Big Sur Public Beta's -- and a mix of Firefox Stable and most recently, a few Beta versions the following happens:

When streaming any form of video/audio via Firefox -- YouTube comes to mind especially -- and swapping between tabs or other Windows or hitting screen resize, pausing/resume.. or just general usage while a stream is happening -- an incredibly weird "scratching" noise is experienced over the sound output. I mainly use the built-in MacBook Pro Sound.

Incredibly difficult to reproduce this, but I am not under high usage/load at the time that it occurs and sometimes am.

Will keep this thread updated if I find a way to reproduce -- but hoping someone else is experiencing this too to assist.

For some reason I can't log into Apples online developer site,


FF says

To protect your security, idmsa.apple.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

which takes you to https://idmsa.apple.com/appleauth/auth/signin?widgetKey=92f19b477c5c9be6ab17f3ec2b1b2b7db4d00a9a8c973e3d6c90dac08b91de71&language=GB-EN&iframeId=daw-73c470e4-b981-4226-ba0b-64a0627e5217&appId=632

All I get is a blank page.


If I do this on the Chrome browser it works

Not sure if this was already reported, since search on this site isn't great and I have to look through multiple pages.

Sometimes some elements won't want to unselect, and stay highlighted until I close inspect element.

I finally figured out why Firefox kept warning me about opening too many tabs at once: this command is the first option on the pop up menu when I click and hold a moment too long on a folder that is part of my bookmarks toolbar (some of these have dozens of bookmarks)

'Open all in tabs'

this is on my Windows 10 PC using Firefox beta.

Is this a command I can hide/delete/inactivate? I'm quite certain I've never wanted to do this and probably will never want to do it, and now on a machine where I use a mouse with right click it is disturbingly easy to click this accidentally. I want to disable the command entirely.

I did check about:config and saw nothing obviously relevant.
