Hello. Our organization is experiencing an issue where sound settings are not carrying over correctly to Firefox. Specifically, this is with speaker settings. In multiple calling platforms (tested in Genesys Cloud and Teams), we are not able to adjust the settings for the speaker that audio plays from. We can adjust the default microphone setting, but not the speaker setting. This is only occurring in Firefox (works fine in Edge and Chrome).

Additionally, we've tried adjusting the default audio settings by going to Windows > Sound settings > App volume and device preferences, and changing the settings specifically for Firefox on this page. This does not work. When we check Teams or Genesys Cloud, it seems like Firefox is just picking any default without a rhyme or reason.

Any assistance would be greatly appreciated.

I had to add Javascript because one of my accounts need Javascript to open. After installing Javascript and allowing for all to be 'true', I still get this message when I try to open a 'show blocked content' in my email.

"The address wasn’t understood

Firefox doesn’t know how to open this address, because one of the following protocols (javascript) isn’t associated with any program or is not allowed in this context.

   You might need to install other software to open this address."

I never had any problem before installing Javascript. Thanks for any solutions.

I can't send emails out of Thunderbird but can receive them, not sure what to do? Is there a phone number I can call with Thunderbird for help? I'm not that savvy with all this.

Struggling with TB constantly "downloading" x 10s of thousands of 10s of thousands of emails (all of which are downloaded), and the programme grinding to a halt. Have set the inboxes to a retention policy of 2500 total. So shouldn't even be trying to DL more than that. Seems to mainly manifest when I compose an email (exactly the time that the sluggishness is a problem). Have done the usual compacting/deleting * files.

This is getting to be a real issue now. I wonder if there's any paid support channels that can deal with this?

Once a while Firefox would freeze up and when that happens it would without fail reboots the phone if the phone goes to sleep and if I don't force close the app quickly. It might've done so anyway without putting it to sleep but I haven't tested leaving the screen on long enough. I noticed that if I was quick enough and force stop the app the phone doesn't reboot, but that window is really short. Maybe 2 seconds or so. Suffice to say force stopping didn't always work since the window is so short. When Firefox freezes other apps and phone functions work normally. It's been ongoing for a while through multiple updates. I see some people have already reported this same issue here. Can Mozilla fix this please? I have uBlock origin addon installed thanks. Also this never happened with my Pixel 3 phone which I was using up until a few months back so maybe it's pixel 6a specific. Alot of people have this same issue with pxiel6a from googling. It can freeze on any site I visit but one example is reddit.

Firefox seems to crash repeatedly and generates no crash reports, just freezes up my pc. It works in troubleshooting mode but even after refreshing, the problem persists. Surprisingly, it will consistently crash if I go to `about:support` (except in troubleshooting mode). Any help would be appreciated!

Firefox will not allow my to post comments on Yahoo. I have no issues with Chrome or Safari. I get the following error message: Your comment failed to publish. Retry

Whenever I open the find bar while deleting the phrases and words, it shows the one word highlighted or its phrase highlighted on the find bar whenever I reopen after deleting the phrases and words. I need help for this ?

Hi,

I have been watching YouTube videos on firefox android and have been clicking ful screen and landscape has been fine. Then over night a few days ago, it stopped. When I turn the phone to landscape, the video sound is playing but the video is blank, with no picture. It is fine in normal portrait just not when I click full screen when it was working.

I've cleared the cache and history, I've even unistalled Firefox and reinstalled it twice, once from the play store and once as the apk but to no avail. I have also disabled adons, tried the picture to picture, and autoplay but nothing works.

Any help to rectify and return my viewing would be appreciated.

Suddenly when I try to go on Youtube, I get messages that I'm blocking ads. I'm on a Mac-mini using X El Capitan V10.11.6, which is the highest I can upgrade to. I'm using Firefox Browser 78.15 (64-bit) and info shows it's up to date. My old Safari browser still will work with Youtube, but Foxfire is my go-to browser.

Keeping got massage: The folder 'Inbox on parkerlin@hochien.com' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.

Have clean up all In box mail and compacted it, but still has same problem .

With just 2 email addresses that I have been using for years, I suddenly get this Undeliverable message when attempting to send emails using Thunderbird:

"The mail client submitted this message with bare line feeds, which cannot be sent via SMTP protocol DATA command and receiving system does not support BDAT"

I can receive emails from the 2 addresses fine, I just can't send to them through Thunderbird. When I sign in to Hotmail Outlook Live I can send and receive to these addresses with no problem.

I'm stumped! Any ideas? Can I reset Thunderbird?

Thanks

Please let me know if speech recognition API is supported in firefox. If yes, provide the steps to configure it without any error. I always get error like Uncaught TypeError: window.SpeechRecognition is not a constructor

I've been a faithful Thunderbird user since the beginning - and continue to use Thunderbird with our company's Microsoft365 deployment

until Monday of this week -- when suddenly I find that my credentials are being refused.

The symptoms

• XXX: Connected to outlook.office365.com
• nothing in the activity viewer
• no email coming in

I've read and tried all the fixes proposed in the article at https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 (restarting thunderbird after each step, naturally)

• have authorized Thunderbird to our Microsoft365 tenant
• created and tried registering with a new thunderbird profile
• have set my security settings to 'accept all cookies'
• have used the config editor to remove 'oauth2.issuer' and 'oauth2.scope' values
• I've checked that my account in Microsoft365 has IMAP and Authenticated SMTP enabled

So, since Monday, I've been living in hell, trying to pretend that the Microsoft Outlook app for macOS is useable, but it's practically debilitating to be forced to use that piece of software.

Can somebody please point me to another possible set of steps that I can use to try and diagnose this?

I absolutely hate myself for having to ask for help on this, but I'm at my wit's end...

Firefox has been a great browser on my new S22 however I have noticed recently that it has been dropping my battery percentage extremely fast, and I notice its lower almost every minute I check. This is confirmed in the battery settings menu where it shows an abnormally high amount of usage, when I mainly use Firefox for general browsing and close background tabs.

Ok, so I installed Firefox today, and tried to watch Discovery+, it kept saying it was installing components to play the audio and video and never seemed to actually install them. I finally figured out it's the widevine plugin sitting there with a yellow bar saying it's going to install soon but never does.

I went through nearly an hour of troubleshooting, and nothing has worked. I tried toggling the DRM option on and off, restarting the browser and PC, reinstalling Firefox, restarting my modem, disabling and enabling the plugin itself, going to all the streaming sites I use, attempting to manually install the plugin, etc.

As far as I know, I'm not using an antivirus, I don't have my VPN on, any other extensions or plugins, pihole, or anything else I saw in other support queries. I'm just going crazy trying to fix this since it seems nothing works.

Hello! Windows 11 22H2 22621.1555 + Thunderbird 102.10.1 (64-bit) I face a problem with Yandex mailbox with the following authentication settings: smtp.yandex.com:465 SSL/TLS OAuth2 The "Enter credentials" window gives --- 400 redirect_uri does not match the Callback URL defined for the client --- after logging into account. The address in the window is https://oauth.yandex.com/authorize?response_type=code&client_id=...&redirect_uri=http%3A%2F%2Flocalhost&scope=mail%3Aimap_full I removed the client_id but "localhost" is authentic and suspicious. What can cause the problem?

I had Thunderbird automatically upgraded to 115. Since then I only see the new emails, all folders and emails from September 12th, 2023 have disappeared. Unfortunately, the restore command doesn't help with MozBackup either; it is executed but with no result. Please describe to me step by step how I can restore the folders and emails.

In this folder: C:\Users\kschl\AppData\Roaming\Thunderbird is just an old profile. Therefore, I wanted to use a backup via MozBackup to restore all data, unfortunately this doesn't work. An initial comparison of the newly created profile also shows the folders, but they are not displayed in Thunderbird - there is an incorrect setting.

Please describe this to me step by step, including in which directory I should store the backup in the future.
