An IMAP mail system is configured on a server running Debian 12. While there are never any problems via webmail, reception and sending work occasionally via Thunderbird 115.9. Even in "Troubleshooting Mode" it doesn't work. The server has good hardware characteristics and there are no applications that can slow it down, nor do I think it is a firewall problem or incorrect parameters otherwise it would never work. The error is related to timeout reaching the server. What can I check to find out where the problem is?

Picture-in-picture since recent YouTube update keeps closing. Is there way i could configure in about:config to never close and always stay open even if page refreshes and have it move the video play back always to the Picture-in-picture window ? If not could this be made a feature in a future update ?

YouTube especially been annoying to Firefox users, cos it keeps refreshing the whole page breaking stuff every time it plays the video, as well have issues with looping videos even tho they are already fully buffered, making entire YouTube experience as frustrating as possible as encouragement to switch to chrome, which i refuse for obvious reasons.

Anything i can do on my end ? If tested if this happens in incognito mode as well with all extensions disabled in private windows, no change of behavior.

Btw this happens on the new YouTube interface with no way to get back to the old interface, cos it keeps the annoying features of the old interface even if you try to re position stuff using hacky ways like extensions that do so, which of course break stuff even further. I just want Picture-in-picture to remain open, and to play current video in picture-in-picture that is playing automatically.

Btw the Picture-in-picture experience with chrome or chrome based browsers is absolutely horrible, giving me even more reasons to stay on Firefox besides privacy related issues and other issues.

So I'll be typing like normal (I type 100 WPM), and all of a sudden, I'll type a sentence, but each individual letter starts taking about 3 seconds to show up on the screen. I have to sit and wait a super long time for everything I typed to finally show up. Other times, I move my mouse over something I should be able to click on, and have to wait a long time for the arrow to turn into a hand, letting me click on it. These periods of slowness will last a few minutes, then disappear.

What's really interesting is that when the slowness starts, I can type just fine up in the URL bar. I might type my entire message there, then copy paste it down to where ever I was wanting to post it. However, when I do that, if I have another tab open and that tab is playing music, the music will start to break up and lag as I type. Again, after a while, the slowness disappears and we're back to normal.

Can anyone tell me what's going on?

MacOS Sonoma 14.4 seems to have broken a number of apps. AFter updating to Sonoma 14.4 I experienced a great number of crashes with Thunderbird, so I completely uninstalled Thunderbird and removed all traces of plists, Application preferences, everything, reinstalled Thunderbird, and added back the two email accounts I use with it. It now takes up to 30 seconds to start up Thunderbird, after which it happily no longer crashes, but obviously the startup time is unacceptable. I experience the same problem with Typora, and the developers there informed me that they believe the problem is with a Sonoma change that broke WebKit. I don't know if Thunderbird still uses Gecko or if the new version is WebKit. Please let me know if other Sonoma users have reported this problem or if it's just my system.

I'm unable to load any web pages since receiving an update 4-17-24 on Windows 11. It doesn't seem likely I'll be able to get another update to fix this via the browser. What do I do? Uninstall?

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 can receive emails to my (protonmail.com server) email account on Thunderbird. But I cannot send emails. This is the error message. "Sending of the message failed. An error occurred while sending mail. The mail server responded: Error: no such user. Please check the message and try again."

Thank you for your help!

Hi Guys!

Can high resources eatin' (maybe graphics, IDK) Ads, for Me in the Webside embedded and (sometimes) with 'movie' like movement decorated, automatically get blocked?

My phone runs slow, 'even' with just 1 Tab open and only Firefox Mobile App on the phone active.

Sorry, I can't see the field I type in currently, maybe I writ a bad layout right now, but content matters XD.

So with Google becoming an increasingly terrible company over the years I once again decided to try to move away from chromium based browsers and over to Firefox, but I'm still having the same problem as I did when I first tried. I have since found the source of the problem, or rather a more exact explanation of what is going on, but I still can not find a solution. Basically when I compare the audio of the same YouTube video while logged into the same account with the same settings the audio quality on chromium browsers seems better. After some testing I figured out that it has to do with Logitech's G Hub surround sound option. Using Logitech's surround sound on headsets that support it, the Pro X2 in my case, will change the audio quality by quite a lot, in my opinion it sounds better. The problem is that this change doesn't seem to have an effect when using Firefox.

Is this a known issue and if yes, is there a solution?

Hyperlink insertion only works in troubleshoot modes but not in main mode even if all extensions and hardware acceleration are turned off (used this guide: https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird#w_the-problem-no-longer-happens-in-troubleshoot-mode)

Please help me.

Thank you!

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

I upgraded to Thunderbird 115.10.0 (x64) earlier today and now the program is no longer closing completely (I've tried using the X at the top right of the window, and I've also tried File menu -> Exit). I first discovered this when I was using CCleaner to clean my temporary items and it asked me if I wanted to close Thunderbird after I had already closed it. I then checked my running processes and there are three Thunderbird processes that remain after the program has supposedy closed (Task Manager screenshot attached).

Any help with this seemingly new bug is greatly appreciated!

Much thanks, -Snipe

OSX 12.7.4

I upgraded to 115.9.0 to get OAuth for some, but not all, accounts. Those on Gmail & Yahoo are OAuth. I have non-OAuth accounts on a Zimbra server, and on Panix.com.

It prompts for the first account's password. TBird then gobbles all available CPU on the machine, and stays there. If I wait long enough, it becomes usable again, but that may well be hours.

However, once it calms down, it works normally.

Intertwined with this is: TBird rejects the Zimbra passwords as I enter them. I retry and retry, and then they succeed. I know the passwords are correct; I've even typed them out, and then copy&pasted them in. I'm not sure about the Panix account, if its password works the first time or not.

I tried restarting in troubleshooting mode; it made no difference.

I have been using Firefox as my primary browser for a very long time. Now, every time I start Firefox, I get a message that the update failed, and that I should manually download the update file and run it. I do so, the update appears to work, and Firefox behaves, until I stop it and restart again. Then I get the same message. I looked online - it appears that others have had this problem, but no clear solution. I am not willing to use Edge, but am beginning to wonder if it is time to leave Firefox. I would appreciate a solution, preferably a reliable one. Thanks, Joe Purvis Email hidden for privacy reasons

This has been happening to me with recent updates of Firefox, and I am very close to dumping a browser that I have used for years because of it. I go to load pages and it just sits there and spins and spins. In the time I take to open another browser like Chrome and copy and paste the exact same links into Chrome, where the download of the web page is practically instant. I go back to Firefox and it is still spinning and it is just ridiculous. I have no clue what would be causing this. After it finally loads a page, it seems fine on subsequent loads of pages.

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

After just turning on my computer running Windows 10, I opened Firefox. I open 1 web site and noticed my computer showed a (16) prefix when loading Firefox. I opened the Task Manager and it showed that there were 15 instances of "firefox" running in the background. All showed a UAC Virtulization of "Disabled". But they also showed using 638.8MB of memory. I do not know whether these are necessary files that must run in the background or if the number of files indicates that my system has been hacked and someone else is in my system from outside. Any suggestions as to validity of these files running or how I might confirm that they should be running. I have noticed the number of excessive background files before but the number is never consistent which makes me fear I may have been hacked.

I'm about the 100th person to have this problem, so I have spent the better part of two days looking at all the threads and possible fixes. Like all the others, with no warning, my TBird stopped being able to send messages through Spectrum. It did NOT start immediately after I updated TBird to 115.9.0 (in March) but just three days ago. I have three roadrunner addresses in TBird, and one other one associated with a website I have. All have the same problem. My phone and my iPad send messages just fine.

I tried all the fixes that worked for some. They didn't work for me; I continued to get various, inconsistent Send Message Errors. I have come back to the recommended Spectrum setup for the outgoing SMTP server: mail.twc.com, Security is STARTTLS, Port 587, Authentication is Normal Password, my username is my email address. Of course the problem is not fixed.

What DID work was putting TBird in Troubleshooting mode, using the Spectrum setup above. While that is adequate, I would much rather find out what is wrong. I have Matt's 10/7/23 11:56 AM answer to someone, asking for the Troubleshooting Information. I will be glad to supply that but I need an answer to this message in order to do that. Thanks! Demaris

I had used and uninstalled Chrome, and others. All I have is FF and ME. Some times when I attempt to open a web page, FF fails and I have to use ME. But other times ME fails and I need to use FF. I recognize that all browsers other than FF are the same or similar basis. So, how can I stick with JUST FF. And not have to keep ME updated or active. Just let ME sit there unused. Why can't FF work with all web sites? Is the problem with them or with FF?

I just switched to Windows 10 from Windows 7. Firefox was working fine, but now many or most pages are garbled; see screen-capture fragments at http://www.fenichel.net/firefox/. I tried a new Firefox 64-bit, but it crashed on most pages.
