So I noticed an issue with certain websites a few days ago. I was trying to make a hair appointment online, it was asking me to fill in my email, and the box wouldn't let me click on it. I used a different browser, and it worked just fine. Same thing today: I was trying to make a lab appointment, the next step was verifying I'm not a robot, I clicked the box, and it had a loading circle eternally. I tried it on a different browser, and it worked within seconds, no loading. I've never had this issue with Firefox before! I tried clearing my cookies and cache, and that didn't do anything unfortunately. Let me know what I can do to fix this problem! I normally loved Firefox and it's my main browser, so I'm hoping to resolve this issue. Thanks so much!

I am trying to send out an emergency email asking for GoFundMe contributions to a very large amount of addresses. Thunderbird has suspended my ability to send emails completely. Please help, this needs to be done immediately. Here's what Tbird is now saying: "Sending of the message failed. The message was not sent due to exceeding the allowed number of recipients. The server responded: <wdr@nc.rr.com> service deferred. Too many recipients in a short amount of time. Please try again later. AUP#Out-1440."

I think this is unreasonable. I understand the need to fight spam, but this most definitely is not that.

Need help figuring out why Firefox has a memory leak after an extended use of Firefox browsing. Don't know if its the result of an extension having this issue, or if its a Firefox bug. I have also provided my troubleshooting information, and a link to my memory usage is listed below for download: https://1drv.ms/u/s!ArspaZQCMwZ-iLU_CckOfLkl9DlETQ?e=MuIqsO Thanks in advance!

Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.

Since upgrading to the last version, 125.0.3 I'm getting tab crashes. Is there any way to go to a previous version? I have not had any issues with the websites I'm visiting until this new version of Firefox.

I prefer using Firefox as my browser (have done so for years), but recently I have noticed inability to open some hints provided on my family trees on Ancestry.com

When I called Ancestry, they suggested I use a different browser (: - but when I did, I was able to open the hints Firefox won't open. What is the problem? I was also told that another Ancestry user had called in previously with the same problem. PLEASE fix this!

If it helps, I use Windows on an HP Envy laptop (have for some time - wasn't a problem before a month or so ago). Will I hear back from anyone as to when this might be addressed/fixed?

My laptop lost power mid-session and since then Firefox hangs after opening and becomes unresponsive. Can’t do anything on it. Troubleshoot mode does the same. Booted up my computer in safe mode, no change.

I’m guessing a reinstall would fix it but I had a bunch of tabs open that I’m really trying not to lose. And I didn’t have an account to save them, I’ll rectify that after this.

Firefox is not opening. Every time I try to use it, I get the message:

" We're sorry. Firefox had a problem and crashed. We’ll try to restore your tabs and windows when it restarts."

I have submitted the crash report: Crash ID: bp-51f17766-7a20-41dc-ae3d-27ab10240501

I am running it on Fedora 40.

Thank you!

I am using Firefox 125 in Windows 11. And this just happens recently.

Sometimes, quite frequently, when I click the addressbar wanting to input or select a new address. The Firefox UI freezes (before the dropdown list of addresses is shown). The video/audio/other effects are still working, and from task manager, it does not cost more CPU/mem than usual. But it does not response to key press or mouse action. All I can do (that I know of) is killing the processes. The problem does not seem related to "current" webpage I am browsing. And I have not installed new addons for a few months.

Any idea what should I look into?

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

I downloaded Thunderbird from Microsoft store. I enter my name, email and password. The first message was "Configuration found in Mozilla ISP database", but the last message was the Error: "Unable to log in at server. Probably wrong configuration, username or password".

Email is from gmail. App version is 115.9.0 (64-bit).

I have tried to restore a backup made with Mozbackup. This was a bad idea. I now have 2 profiles xxxdefault-beta and yyy.default. So I asked Tbird to install from yyy.default where i've got my recent emails and it tried to import without success. I humbly ask for some options. Can I merge 2 profiles ie copy them into one profie folder? Can I hide/rename the profiles then delete Tbird and install anew? I promise on my grandmothers skateboard I will never use Mozbackup again, + . As an aside in appdata,local,tbird,profiles,yyy.default,cache2 there's a whole bunch of alphacoded files. what do these do?

Hello, have been scratching my head for a while on this one. Have a freshly setup install of Debian 12, using Sway (wayland) as my Window Manager. I am really struggling with slowness in Firefox, page loads take easily 15 seconds whereas loading the exact same page in another window at the same time with Chromium Debian build has near instantaneous load times. I've tried the following troubleshooting steps: - Created a new firefox profile - Tried "Troubleshooting Mode" in Firefox - Disabled ipv6 in firefox about:config and in Debian - Tried different DNS servers - Tried different non-debian specific builds of Firefox - Tried Firefox Beta and Firefox Nightly for Debian

None of these steps made any difference, and Chromium has continued to be significantly faster. Am really stuck here and would love to get to the bottom of this as Firefox is the only browser that works with a HiDPI display in Sway without blurryness. Happy to provide any and all diagnostics and reports that are needed. Thanks in advance!

EDIT: It seems to be some kind of networking issue, using a VPN solves it. But still doesn't explain why Chromium would behave differently.

Thunderbird processes in version 125.0 are not exiting cleanly, just like it was in v115.10.1; user intervention is required via task manager to kill the the open Thunderbird processes, before Thunderbird can be restarted.

I'm using Firefox 124.0.2 (64 bit) on Windows, and every few days I get the error about using an older version of Firefox, with Exit or Create New Profile options. I then run "firefox -allow-downgrade" from the command prompt and everything works fine... for a few days, when it happens all over again. This only started happening a couple of weeks ago, but it's getting really annoying. How do I stop it (short of using something like Waterfox or Brave).

Hello, I am trying to send emails from my iCloud account and it always fails due to the SMTP server timing out. I've tried making a new app-specific password, deleting and re-adding the account in Thunderbird, and made sure the authentication settings are right, but it still doesn't work. I can connect to the IMAP server just fine.

After clicking the Thunderbird to enter my email the whole system goes through connecte3d to uepat624@gmail.com then up comes a message from Thunderbird indicating "you may have too many cached connections use IMAP Advanced Settings to reduce cached connections" Then things continue on for probably 5 to 10 mins. sending login info, looking up IMAP, checking mail server capabilities, looking for folders, sending login, opening folder box, downloading

Eventually email inbox and messages come up. I can send, receive and send mass mailings but when you read a message and want to go back to the inbox you have to scroll all the little boxes at the top of the screen back to the one that says "inbox".

I need someone to remove the cached connections. Pat Blackburn

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
