I previously had a MetaMask extension on FireFox and it would open as usual. Several days ago, I opened Firefox and the MetaMask icon in the upper bar wasn't there. I tried to download it on the browser several times and eventually got the download and entered the seed phrase and, with some outside help, established the extension again and recovered my tokens. So all was good. But today I opened my FireFox and the MetaMask was missing again. Can you please help me find out why it is missing and how to keep that from happening again. Thank you

For some reason it seems like under windows 11 with a HDR display, websites like YouTube don't allow for HDR media playback. This is really disappointing and a major flaw as HDR media is definitely the future. And this has been working just fine in any chrome based browser for years now.

Is there any way to enable this?

Thanks for your time and help.

Firefox Reader view is being defeated on some sites even though Firefox shows the Reader view icon. Example, on CNBC.com news pages clicking the Reader view icon replaces an article’s content with a CNBC page about their cookie policy, e.g. try using Reader view on https://www.cnbc.com/2022/08/26/iphone-gestures-and-hidden-menus.html Is there some way that Reader view can be made to work on these pages?

Currently I use Firefox and Brave Browser, I want to use only Firefox, but the lack of an option to create shortcuts like in Brave is what prevents me from doing that, these shortcuts are extremely useful and practical, but in Firefox the only way to do this is through links that will open in the browser, which is practically useless because I can create shortcut links within the browser itself. I also performed a procedure in the browser's advanced settings so that I could have this option, but it doesn't work either. So I was wondering if there is any other way to do this.

The (Download>save file as )function is completely F'ed up. Upgraded from Ubuntu 20.04 to 22.04 today. That included an updated firefox. Now when I download and save a file as function when I enter either a letter or number to rename the file the Search window pops up with options, or no options, that are available in the directory I'm saving to. The key or mouse focus is now in the Search box and not in the renaming the file box. That means in order to rename a file you have to switch back to the 'renaming the file' box fro the 'Search' box every time you enter a letter or number. Totally F'd up.

Hello, please how do I set up the browser so that the duplicate tab opens next to the one I want duplicated. Now the duplicated tab opens at the end of all the open tabs which is really annoying and not logical at all. I am using windows 10. Thanks

Today I stumbled on an issue that seems to have affected a number of users who care about profiles. The issue is articulated well here. It appears that a clean installation of Firefox results in the creation of two profiles, one called "default-release" and another "default" where "default-release" is the default. Ugh.

Can any user safely delete the "default" profile and rename the "default-release" profile to "default" to restore a simple, uncomplicated configuration? Why wouldn't Firefox do this by default?

I understand from question 1264072 that Firefox did this intentionally to support multiple installs and release channels, but why shouldn't the "default" profile be used by default? Surely a user who is not performing multiple installs or dealing with multiple release channels shouldn't have their profile names polluted by unaffected concerns.

I have suddenly lost all audio in firefox using youtube. My Audio works fine in windows and i can play and hear all windows sounds, mp3 etc...The audio also works fine in Edge browser and Chrome browser. So it looks like an issue with firefox, The audio is not muted or disabled in any way its just silent when playing back youtube

Any help apreciated

I am running Unix Ubuntu 22.04 with Firefox 104.0.01 (64 bit). My Canon LBP 6230DW works fine in my word processor and in Chrome, but it does not show up in the Printer destination field when I am in Firefox. The only print option is to "Save as PDF." How do I get the Canon to be a print destination in Firefox?

Hello!

I'm having an issue with Netflix, i am unable to play anything there at all. It always shows a message saying "firefox is installing components needed to play the audio or video on this page" and refuses to load anything, showing an error, F7701-1003.

After some investigation, i found out that the issue is with Firefox not loading "Widevine Content Decryption Module provided by Google Inc.". I have seasrched and tried several troubleshooting processes, and was unable to find a solution. Refreshing, reinstalling, manually deleting the profile folder, all fails

Trying to use ProctorU with Firefox 104.0.2 on Windows 11 Home, and I am getting the following message : "Monitor Count : You may only use 1 monitor during your exam. Your monitor count could not be found". I searched for possible fixes, and someone mentioned removing fingerprinters, and possibly also remove cookies and tracking content from Firefox enforcement. I removed all 3 and that did not help. I also tried clearing cookies and site data and also cached web content, this did not help. Is there some other setting in Firefox that might be preventing the detection of the monitor count? Any suggestions on how to fix this issue?

Hi

I exported all my firefox passwords to a csv with the option in about:logins.

Now i wanted to reimport them and set signon.management.page.fileImport.enabled = true, restarted firefox, opened about:logins, menu option import from csv is present, selected the exported csv and nothing happens.

There is no error massage. A you seriously telling me that since lockwise has been abandoned about 2 years ago that there is an option to export the csv but NO freaking possibility to import it?

How for god sake should i get my >500 Passwords back into firefox?

Chrome does import the csv exported by without a hassle by the way.

In the previous versions of Firefox, when selecting a language of input, all the other languages were unselected. This was a much better option than today's, where they remain selected, allowing to check in several languages simultaneously. The problem with that is that when a word exists in both languages with a small difference (accent, two letters reversed or something like that), if there is a spelling mistake, it may not appear. In the example below, "defense" should be with an accent: "défense".

I have lost access to my e-mail account that I registered Firefox Accounts with and now I can't login to my Firefox account despite knowing the correct password because it insists on entering a code sent to the e-mail address I have no longer access to. Is there any way I can login to my Firefox account only with my current password to change my linked e-mail address? Or somehow ask support to change it for me manually? If none of that is possible, I want to, at the very least, deactivate or delete said account because I'm worried about the possibility of abuse.

I have been using Firefox for many years. Suddenly I cannot get any sound from videos in Facebook, YouTube or anywhere. The settings in Privacy --> Permissions --> Autoplay are set to "Allow Audio and Video". There is nothing wrong with the computer as I can play videos and sound files on it with no problem. Sound is no problem on Internet Explorer or Microsoft Edge. It is just Firefox that after years of use the sound as stopped working. Can anybody help?

I have Firefox installed on Linux (Fedora), Windows, and macOS, and on Windows and Mac, I can use ctrl (cmd on Mac) + shift + Y to open the Bitwarden extension. On Linux, this instead opens the downloads library (which is normally ctrl + shift + j...). Is there any way to change the shortcuts on Linux to be the same as the other two OSes? Judging by the many many open questions on this site about changing shortcuts, I'm not holding my breath...

I have the volume control all the way up. I turn the volume control on videos all the way up. I have just updated Firefox. The sound is too low. Is there an add-on? It used to be OK, not now.
