v115.10.1 I made a mistake setting SMTP credentials, wrong protocol, and it just stays on Sending dialog. So I abort when I realize I made a mistake and come back to mail I was to send. - but 30-60s after I aborted comes an error message saying it timed out

So the cancel button does not really cancel the send attempt, it seems.

Not sure where to report bugs, so do it here. Thanks.

v115.10.1 32-bit Changed isp and email completely, and wanted to change both server name and user name. But editing server name and leaving that field I get a popup wanting to restart - problem is I need to change user name as well or no go

So it starts to try and login but fails of course, since user name need to change too.

This really need another approach, maybe not so automatic.

Changing focus from first field to next one should not execute restart. - just when leaving second field if any of first and second is changed

So going through all accounts and failed logins etc all the way is cumbersome. - dual restarts every account

Not sure where to put bug reports like this. Thanks.

I like Firefox and am using it for years, but I cannot accept lengthy loading time. I have a fast and stable internet so this is not the problem. Please let me know what the problem is and how to fix it.

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

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

Dear friends,

Firefox on Linux does not allow entries in forms that are called up in IFRAME. It works perfectly on Android.

Does anyone know why this is the case? Uwe

Firefox 127.0 (64-Bit)

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

Thunderbird 115.11.etc has become seriously slow when deleting or moving emails - the first one goes quickly but then it all slows down for the second and subsequent emails. I have found that this is a Virus checker issue - I use Microsoft's own defender software on Windows 11 - and have now eliminated the problem by making an exception in the virus software to the TB profile folder. My question is: how safe is this - I don't want to allow virus attacks in email but at the same time I don't want the slow software! What do you suggest? Thank you

I am trying to access websites that use three.js. When I initially start, the website runs too slowly to be usable, but if I tab out for some time and then tab back in, the website runs at normal speed for a bit before slowing down again. I cannot find any solutions to this problem nor anyone else who had the same problem as me.

Good Morning. I have been using Firefox for 20+ years. Last night it did an update overnight, and this morning I am getting "The Page Isn't Redirecting Properly" error message on my business CRM site. This appears to be the only site having an issue. I have never had this error previously.

I tried all suggestions already including clearing cache/cookies, checking settings, delete history, troubleshoot mode and nothing. The site opens fine on Chrome and MS Edge.

Any additional help is appreciated, this is very frustrating.

Thank you.

I can't remember when this problem started, but the volume dips down for maybe 1-2 seconds shortly after the start of anything with sound, like YouTube videos and MP3s embedded in a website. On the same phone with Chrome, the problem does not happen.

Has anyone experienced this? I made a screen capture that demonstrates the problem, alternating first with Chrome, then with Firefox (then both again) -- https://youtu.be/GB116jauaX4

Any help anyone could provide would be greatly appreciated!

Websites say that my Javascript is disabled, but I already checked on the about:config website and the javascript.enabled is set to true. What do I do so these websites accept that my Javascript is enabled?

for a recent update or two, when I am watching videos in fullscreen, at least like me, for example, when I entered fullscreen, the video should play horizontally, but after merely half a minute, the screen orientation goes back to vertical mode automatically, which is not happening when I began to use Firefox android months ago. Watching same website on different browsers, only Firefox goes wrong, so I think this should be Firefox's bug.

In English, the meaning of this error is: Title: Configuration error Content: Failed to read configuration file. Please contact your system administrator.

I had this error for a long time. But it's not too serious. Just hit ok and I can use all the recovery tabs as before without any problems. But every time I open windows and open the browser, this message appears. I feel very uncomfortable and tired without knowing why. Even reinstalling the browser didn't fix the problem, I tried it before and lost my favorite browser theme. And 1 more thing if someone can explain. If it can't read the configuration file, how can I still use the browser? What does that configuration file do?

This message only appears when I have not opened the Firefox browser on my computer. If I already have the tab, I can open another firefox browser without that message appearing. Only when I close all tabs. Open it again and it will appear. And click ok to use normally.

I see that others have had the same problem as me. My trash folder has many thousands of duplicate emails. If I block delete them it will take days to complete. So 3 questions 1. How do I stop duplicate emails in my trash. After deleting many reappear with the date 01/01/1970 2. Is there a faster way of deleting. I use select email>shift key>find last email>delete 3. Is there a limit to how many emails I can put into the block mentioned in #2

For many years, my wife and I have each used Thunderbird on our own computers. Several weeks ago, when my wife turned Thunderbird on, a new screen appeared that mentioned account setup and directed her to set up her existing email address. When she did, a home screen appeared that was significantly different than the one she had been using. But more than that, she lost all her saved emails and Thunderbird started to reload emails. The reloading ended with over 1800 “new” emails whose dates reached back for almost a year. Since then, after some work, the home page has been returned to its earlier look; downloading, sending and deleting are working as before. Missing are a few important, personal subfolders. We’ve tried a few things that we thought/hoped would return us to the point before everything went crazy. That hasn’t happened. Recently, we looked at the Profiles folder on each of our computers and saw something that, I think, is unusual and, I hope, might provide a way get her back at least some of what was lost.

The route to my Profiles is C: > Users > Me > AppData > Roaming > Thunderbird > Profiles In Profiles are two folders, one ends with .default and the other with .default-release. The only thing in the default folder is the file times.json. The default-release folder contains many files and folders, including the Mail folder. The Mail folder contains two subfolders: Local Folders and mail.comcast.net.

On my wife’s computer, there is only one folder inside Profiles. The name ends in .default. Inside that folder is the Mail folder. Within the Mail folder are six subfolders: Local Folders, Local Folders-1, Local Folders-2, mail.comcast.net, mail.comcast.net-1, mail.comcast.net-2. The Date Modified date for Local Folders is probably the date the problem started. Date Modified for Local Folders-1, mail.comcast.net and mail.comcast.net-1 is the same: a few days after the date for Local Folders. The dates for Date Modified for Local Folders-2 and mail.comcast.net-2 are the same, and change daily.

I’m hoping/assuming that the missing, personal subfolders are in one, or more, of Local Folders, Local Folders-1, mail.comcast.net, mail.comcast.net-1. What I’m asking here is: does anyone know of a way to easily locate and recover the subfolders and, then, move them into the correct location in Local Folders-2and/or mail.comcast.net-2.

Thanks for taking the time to read this long story.

I have several Comcast.net accounts that I have set up in Thunderbird. About 2-3 times per week, Thunderbird makes me re-enter one or more of my passwords, only for the comcast accounts. It says Authentication Failure, but I have not changed anything on the accounts, including passwords. Entering the same password works - for a while. Any idea how to stop this?

In my list of Inbox Unified Folders (13 of them), one folder in particular (the second one) is sometimes there, then at some point later is gone. It's still in the 'All Folders' list, but not in the Unified folders list. If I kill TB and restart, then it's back. I have no idea what ops might cause it to vanish. Any idea what's causing it to vanish or what I can look at?

I opened Thunderbird this morning and there were no issues. Closed it and just now reopened and I'm getting this message: Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

It downloaded 28 emails but will not let me see/access them.

Can anyone help? Thanks, Linda
