Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

How can I turn this message off? Some sites I visit give me that message, it shows up when I'm typing a reply to something which pushes the page lower and fouls up my ability to keep typing, then if goes away, comes back, goes away ... I just want to kill the message entirely. I'm not worried about speed, there's nothing to fix, I just want the message gone.

I have tried to disable hardware acceleration, refresh firefox, reinstall, and nothing works. It hangs every single time when searching on google or connecting to websites. This really sucks because I have used firefox since the beginning and don't want to have to stop now..

Video playback initially works, until suddenly it doesn't; no new videos will work, and videos that previously played in the same browsing session will stop working. Easy to reproduce on Reddit by browsing any video-heavy subreddit. Leaving a broken video in a tab seems to infect the rest of the browser across websites; if a broken video from site A is open in another tab, videos on site B won't play.

Sometimes quitting and restarting Firefox is enough to temporarily get video playback working again; sometimes I have to manually clear the browser cache; at least once I've had to reboot my phone.

Hello,

For an unknown reason, my firefox sometimes is really slow to startup.

It can take up to 10 minutes before the webpage start to load. My hardware is not that bad. I try to use the "performance" to capture the issue : https://share.firefox.dev/3x2rgHj I don't know if there is something to see because, the tool is also slow.

It happens on 3 different computers on linux.

I try to disable all extensions and without telemetry but nothing change. I'm reporting the problem now but it's much older

If you have a idea to fix this issue please share because it's really annoying.

When I open Firefox. Firefox Will NOT open any websites. If I disable ublock origin then enable again Firefox works but I get all the ADS. What I have to do is: Close firefox and restart Firefox but then I get this message "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." Sometimes I have to restart Firefox as many as 10 times before Firefox works. I got to the point where I stop after the second try and just switch to Brave browser.

Before: Firefox use 99%. Brave Use 1% Now: Firefox use 75%. Brave use 25%

Google search no longer works on Firefox. Other browsers have no problems. Changing the default search engine on Firefox works (eg Bing), BUT. It can now find Google Maps, but Google Maps cannot find a location, because it uses a Google search. I tried the fix in about:config, but it had no effect.

Hi,

I am using Firefox for Linux, and whenever my yubikey is plugged in, firefox will start bothering me for a pkcs#11 password. It always happens on start-up but it gets relentlessly annoying if I happen to be on a site which potentially utilizes certificate auth, which I do not use this yubikey for.

I do however use it for 2fa, which does work perfectly fine.

How do I permanently stop whatever Firefox process keeps bothering me about this PKCS#11 password for functionality that I never use?

I've been running Thunderbird for years on Gentoo which has version 115.10.1 as the most recent. I don't send much mail so I'm not exactly sure when this problem occurred, but I'm unable to authenticate with my SMTP server. I have not changed any configuration. Some weeks ago a changed my password on the server, but I made the appropriate changes to Thunderbird password manager. All settings, username and passwords are 100% correct as I copy pasted all of them. IMAP on the same server (uses same credentials) works.

I have tried deleting and re-adding my accounts which did not help. I have also tried deleting my profile folder. All other mail clients (e.g. claws-mail, kmail, mailspring) with the same SMTP server don't have any problems sending mail. This problem seems to only affect Thunderbird and Thunderbird forks such as Betterbird.

I have no firewall and am using SSL authentication with cleartext password on the SMTP server.

I get the following output to console on attempted sending of message:

console.error: (new Error("Server error 503 Service Unavailable", "resource://services-settings/Utils.sys.mjs", 390)) console.error: mailnews.smtp: "Command failed: 535 Incorrect authentication data; currentAction=_actionAUTHComplete" console.error: mailnews.smtp: "Authentication failed: Incorrect authentication data" console.error: mailnews.smtp: "Authentication failed: Incorrect authentication data" console.error: mailnews.send: "Sending failed; Unable to authenticate to Outgoing server (SMTP) mail.kapsi.fi. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'., exitCode=2153066805, originalMsgURI="

like the subject says the video on disney plus is very choppy/blurry/not 4k like it should be can u guys look into it? the video is blocky and blurry on firefox but not on chrome for some reason and id like to fix it soon

Within the last few days, I've noticed I'm losing functionality in certain online apps through the Firefox browser.

When I'm on Instagram, I can't check direct messages: the function stalls out without resolving.

In Gmail, I'm unable to embed an image in an email. I can attach it like normal, but the embed button doesn't respond.

In Starry AI, I'm unable to use any menu options at all, I'm stuck at being logged into the account and can't logout, check my settings, or request help. I receive this message: "Application error: a client-side exception has occurred (see the browser console for more information)"

When I follow up on this, I get this pop-up message: Resource of last-private-context-exit is missing a browsingContextID or innerWindowId attribute resource-command.js:917:13

What can I do to fix this issue?

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

I just started having an issue while watching Live Streams on Youtube with FireFox. I'll load the live stream and it will run for about a minute then it will switch to the streamers previous recorded stream. I opened Youtube on my iPad and on Edge browser and the Live stream keeps playing the live stream but on FireFox it only lets it run for about a minute before flipping the playback to the previous recorded video of that streamer. I tried clearing my cache for Youtube and I have no extensions running. I have Youtube Premium and run no adblockers. I have also tried safe mode but the problem persists.

Any idea what could be happening?

I just noticed that if I check the SENT folder, some of the emails I sent have this text in the body part.

"This is a multi-part message in MIME format.

Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 8bit

[HERE THE CONTENT OF THE EMAIL I SENT]"

I'm wondering if they are sent like that, what the receiver will see and if there is a way to prevent it.

The email account is using IMAP and as far as I know it happen just to that specific email account. The emails are sent using Thunderbird. I'm using the latest version of Windows on a laptop. I'm using the following Thunderbird extensions (latest versions): - Compact Headers - Send Later - Mailmindr - Quicktext

Hello Good People,

I noticed that the snap version of Firefox had a lag issue when typing into input field. For example, when composing an email and wanting to use backspace to quickly delete a misspelled word, then backspace works slowly, stuttering and jittering. If I hold down a key in the input field it also lays the character down in a stuttery, slow way.

I tried reinstalling the system and that solved the issue. But it has returned again. Maybe it was an update. I also installed WINE and waybridge to get some windows plugins to work on my DAW. I don't know if that has affected it.

I also tried removing the snap version and installing firefox using the terminal but the problem persisted.

It's an annoying problem. Any advice appreciated.

Hi. I have used Thunderbird for a long time. I have never had a problem accessing my hotmail account for emails. Overnight Thunderbird now posts error message boxes when trying to login to the hotmail server. It reports incorrect username or password. Neither has been changed by me and comparison with Eset Password Manager shows them to be correct. I can login to Outlook online using the same login credentials an get my emails that way. I have also changed my Outlook hotmail password while logged in in my browser and updated everything on the PC to match of course.

I have massaged the server Settings for hotmail and have had the system working again, for a while. Twice I have reset the settings to a different server and back again and that seems to clear the problem for a while. Then the error messages switch on again consistently. At this moment using "File" -> "Get New Messages For:" -> "Hotmail" works without any problem and the automatic scheduled checking reports "No messages to download" so it appears to be working. But that is after just coming back to my PC to find a string of failed attempts, each with its own error box, which have appeared since I last "fixed" the problem and assumed it was now fine.

My server settings are Type: POP; Name: pop-mail.outlook.com; Port: 995; Username: same as for browser access (which works); Password: As in Thunderbird's stored passwords matching Password Manager and working browser access.

In my paranoia I have even wondered if I am being locked out by Microsoft somehow. Can anyone suggest what is going on here?

Nvidia RTX Super Resolution seems to only work very rarely or not at all compared to the Chrome version. In some instances it will upscale the Full-Screen Video. It will not interact with windowed videos at all. But it will never upscale a windowed version that exceeds the playback resolution.

Steps to reproduce for windowed videos:

1. Open any youtube video
2. Set the resolution to 480p or lower (as I am using a QHD 2560 x 1440p monitor)
3. Playback the video and monitor Nvidia Control Panel to see if Super Resolution has activated.

Observation for windowed videos: Feature works in Chrome. Feature does not work in Firefox

Full-Screen and Super Resolution: I have no idea what is going on here, on very rare occasions it does work, for the most part it does not work at all. If I had to give a rough idea of when it works, I would say that it is more likely to work when Firefox has been freshly launched.

I could neither see an active change in the Control Panel, or notice anything in the video quality. Both a quality change and feedback in the Control Panel occur when using the feature in Chrome. I have tested on identical links, with identical quality settings.

I tried:

• setting the Super Resolution Quality manually, instead of manually
• an incognito tab

Started getting error April 10. I have SSL/TLS and Oauth2 set for Thunderbird account server and smtp. Looked thru lots of web messages - no joy. Via web browser I can connect to my Yahoo email without issue. My gmail account on Thunderbird still works fine (with its unique third party password). I am on current Thunderbird release 115.9.0 (64 bit). I disabled the only add-on that Thunderbird was using. Windows 11 Pro which is up to date. Plenty of open disk space. Have rebooted my PC multiple times.

Looking for suggestions Thanks Bob

Dear Support,

suddenly my INBOX file has a size of 480GB - the mails in all my IMAP folders online is less than 4GB.

How can that happen?

Is there a fix or should I just re-create the account?

Best wishes, Johannes
