When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

I have been playing a game on facebook for years. 4 days ago It stopped working. Other players are saying that they had to switch browsers ( to Chrome and others) and they are able to play the games. Why can I not play on Firefox?

Scrolling in Firefox is causing any webpage to scroll many lines at once with a single click, and it seems to be exclusively happening to Firefox, as every other application scrolls normally. I have tried searching here and elsewhere for a solution, and I have tried to change about:config settings based on the recommendations I could find to no avail. I have also tried to refresh Firefox and have used Troubleshoot Mode, but those too have not worked. I have no clue as to what could have caused this, as I have not been messing with any settings prior to this.

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

When I try to open Firefox I am getting this error message: Error: platform version '124.0.1' is not compatible with minVersion >= 124.0 maxVersion <= 124.0. Does anyone know how I can fix this? Deb PS I need simple instructions, I'm not terrible techy.

Support,

The USPS website does not work properly with Firefox!! The Home page loads okay but there are multiple other issues with links not working. For instance all of the links under Quick Tools do not work except this one: https://www.usps.com/manage/po-boxes.htm. Other things don't work either.

Everything works fine that I tried with Google Chrome though! Please address soon.

Thanks

I am having an issue where youtube videos played at higher quality stutter when put to fullscreen. Up till about 720p60 works fine, at 1080p60 and above the framerate becomes unstable.

Things I have tried: - I have tried going into media.media-capabilities.enabled and changing it from false to true - I have set network.buffer.cache.size to 262144 - I have disabled all my plugins - I have tried changing my user agent to windows/chrome

My current setup: Firefox 122.0, Macbook pro Sonoma 14.1, Apple M1 Pro chip

Curiously, if I make a new firefox profile and play a video there, there is no stutter. Does anyone have ideas on how I can fix my current profile?

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.

On my laptop (121.0 on doze 10) I have no problems but on my desktop Firefox (121.0 on doze 10) started to struggle with Google a few months ago. Sometimes the Google site doesn't load, sometimes it loads but doesn't connect (no auto-complete, no search) and if it does work the result links often don't load when clicked. It's like Google falls asleep and then, when it wakes up, all is fine, until it nods off again. I have followed advice provided, cleared cache, cleared cookies, removed plugins and extensions, reinitiated and reinstalled. Running in safe mode seems to help, as in pages seem to load faster, but sadly does not eliminate the problems. Other browsers on this machine are not affected. No time sync issues.

Any suggestions?

TIA

When streaming a video and using PiP, after opening another window or program and then pausing said video that is currently being played on the PiP player window, sometimes this causes the actual video itself being played via the PiP player window to freeze. So the video is paused and I want to resume play but when clicking the 'play' button on the PiP player window the video refuses to play.

The only way to clear this bug is to click the 'close' button or the 'back to tab' button on the PiP player window and then refresh the actual web page. After refreshing the web page and repeating the same steps - the PiP player window works just fine with playing and pausing, but it's annoying that I have to do this.

Hello,

For a few days I have had the following message for my outlook mailboxes "Login to server imap-mail.outlook.com failed."

I tried to change the password, I tried to remove the address and put it back but nothing to do the message is still there... Do you have a solution?

Of course I use the latest version of thunderbird!

I have a Lenovo ThinkPad X1 Yoga Gen 6 (20XY005MGE) with Win11 Pro.

All of a sudden, Firefox does not play any sound. I notice that it does not show up in the volume mixer. I tried:

• this solution: https://support.mozilla.org/de/questions/1278299
• Reboot the PC
• Uninstall and reinstall Firefox
• Deactivate all Extensions
• I worked my way through the manual pages (none of which mentions Firefox missing in the volume mixer)

Youtube does not play sounds, the Spotify page notices that it cannot play sound (the spotify App for Windows works fine, though). News sites (tagesschau.de / video, deutschlandfunk.de / audio) play the video, but no sound.

I had the problem a few months ago already but I cannot recall the solution :(

Thanks for helpful hints!

I have been successfully using Thunderbird for many years. In the last year or so I have been noticing that occasionally one of my sent emails gets corrupted such that the email body starts showing html text and the email subject header is changed to another email header that exists in the same folder but is unrelated to the email body. When I check the corrupted email from the Gmail web user interface, the email is not corrupted. I tried repairing the folder but to no avail.

I attach an example of a corrupted email below:

From Content-Type: multipart/alternative; boundary="------------NlJPhaGMpTt1f7wbEHlOvxNE" Message-ID: <4bf83075-b571-4214-921b-09f4582e6e58@jesuit.org.mt> Date: Thu, 4 Jan 2024 10:25:56 +0100 MIME-Version: 1.0 User-Agent: Mozilla Thunderbird Subject: Re: Minutes of SCPC Meeting Content-Language: en-GB To: Charlotte Attard <charlotte.attard@staloysius.edu.mt> References: <AM9PR10MB487111674D307583B8DB6AD3D195A@AM9PR10MB4871.EURPRD10.PROD.OUTLOOK.COM> <AM9PR10MB487106F96E9E404BDA477808D167A@AM9PR10MB4871.EURPRD10.PROD.OUTLOOK.COM> From: Stephen Scerri <stephen.scerri@jesuit.org.mt> In-Reply-To: <AM9PR10MB487106F96E9E404BDA477808D167A@AM9PR10MB4871.EURPRD10.PROD.OUTLOOK.COM>

Yes Charlotte - please proceed - sorry for delay

Noticed my phone having terrible battery life, from battery usage you can see that Firefox is highly likely one of the main culprits. I have observed the same over a few days on the last two Firefox builds. It seems that it's not respecting the "Restricted" battery usage in Android (or Android is not restricting it, I have no idea), but you can see today's battery usage linked here: https://photos.app.goo.gl/pMByjqq6Q5GigcQu8

I am using Thunderbird v 115.5.1 on a Windows 10 system. I am using an "@hotmail.com" email address. I seem to be able to receive emails just fine, but face an issue sending out emails. When I press "send", it gets stuck on "sending message" for quite a while, then I see the error message:

=

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again.

=

My SMTP settings: Server Name: smtp.office365.com Port: 587 Connection Security: STARTTLS Authentication Method: OAuth2

Appreciate any help! :)

I have used Thunderbird email for many years. Starting today, I am not able to send an email. I get the following error message:

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: p-impout007.msg.pkvw.co.charter.net cmsmtp Connection Rejected - see http://www.spamhaus.org/query/ip/24.106.196.86 AUP#Out-1220.

When I go to that web address, the web page says "Invalid Input".

What do I need to do to fix this problem? My email address is gbeale@ec.rr.com

My ISP had provided the IPv6 service, edge/chrome/vivaldi are all IPv6 first and working well. Only firefox insists use IPv4, although it could also pass the IPv6 test on https://test-ipv6.com, and the internal test on https://detectportal.firefox.com/success.txt?ipv6 It leads to some webpage extremely slow, even could not be accessed.

I've tried privacy mode, but the problem is still there. IPv6 in about:config is enabled, all related options are default. Is this a bug, or if there is any way could fix it by some special settings?

Waiting for your help, thanks.
