I am at a clomplete loss here and after hours of googling and frustration I just need someone who can help.

- I purged all installation folders and paths, deleted profile and reinstalled Thunderbird 115.1.1 on absolutely (!) clean sheet, it is dead on and I inspected all versions and folders.

- I hoped that the version fixes my login issues, but if anything, they're worse and the logins don't last nearly as long as they used to.

- I am aware of the imap, smtp and tls configuration

- I am aware of the settings in gmail, also tried all combinations of oauth2, less secure apps, app password, I tried all of that

- tried enabling javascript manually, cookies, checking all local browsers, especially firefox browser and legacy IE options for anything that could be wrong

- I can set up and add my gmail accounts, usually once upon install. It will then work with no issue, receives and sends mails, loads all sub folders. It just won't stay.

- I can go to account/privacy and view and edit my passwords. I can enter the correct password there and the account itself works and loads mail. If I close and re-open TB, it's still fine. On the 4-5th time of opening and closing, it locks up and starts promting for sign in.

- I get logged out of one or multiple accounts and get promts to sign back in. These login page windows then cannot be interacted with, at all. They are not displayed correctly, the buttons are just dead and do not react or lead anywhere if I click. Some do the little brightness animation and recognize that I clicked, but nothing continues. I have no ability to enter or submit the gmail credentials in there.

- I tried navigating those with on-screen keyboard, CTRL +, also with scroll wheel etc., it cannot be resized or interacted with. Also changing the window and screen scaling size (100%/150%) does nothing, I also checked all actual browsers like firefox and chrome and they all have normal zoom, cache and cookie settings. Why is the login page not usable?

I know it would probably be fine after reinstall but I just cannot keep doing this. It does not last even a week. I even deleted the profile and re-setup everything several times already, it still comes up with login pages all the time. And if those are not usable then I cannot go forward.

This is all on a fresh Lenovo Thinkbook G15 that is nearly new. I have never seen software not work this vehemently. I have given all info that I have and all that I tried. Can someone please advise, I don't understand it anymore.

Hello,

When I close Firefox after the last update (current installed version: 112.0 x64 Windows 10), Firefox creates almost 200 processes (in the latest case 177), each using from 17 MB to 65 MB RAM (except one that is using over 200 MB - I guess the main one) using 100% CPU for about half a minute, and in that my PC is unusable - everything hangs. It takes a bit more time to close all of them.

Any ideas what could be wrong and how to fix it?

Thank you.

Hi all,

I feel like this is a problem that must have been experienced and solved a thousand times... however I've tried all the suggested fixes I can find and the problem still persists.

When I load Firefox the pages take ages to load. It doesn't matter what the page is, it takes ages, except that about: pages load fine, no problem. When I say pages take ages to load, I mean that everything about the page takes ages, not only the next, not on the images and other content etc, everything. This only started happening today and I only created a new profile a month or so ago. I don't have many tabs open (maybe 20) of which 9 are pinned. I do have lots of extensions installed.

I've tried troubleshooting/safe mode, that makes no difference.

Private browsing and loading another profile are fine, they don't have this problem.

I've cleared all cache and data, cookies, etc, including startup cache.

I've deleted the content-prefs file, and removed places files.

I've tried disabling and enabling hardware acceleration.

I've tried disabling TRR.

Probably some other things too, but so far nothing has worked.

Suggestions please! :)

After an update yesterday, thunderbird v104.2 opens up as a blank window. The menus show up and it seems to download messages, but I'm unable to see any folders or messages. I've tried deleting the "global..." file, I've uninstalled and reinstalled an older version, and nothing is working for me. I've read other threads about this issue and tried the solutions, but have not found one that works for me. I'd appreciate any new ideas. I'm running on Windows10 thanks

Hi, For about the last month or so, the Yahoo mail tab closes itself after I click on an email attachment to open the download dialog box. This happens exactly 30 seconds after clicking on the attachment, whether or not I go on to open or save the attachment. It does not happen if I merely 'preview' the image. I don't know if all attachment types behave the same, but it applies at least to jpg and pdf files. The tab can be reinstated via History/Recently closed tabs.

Firefox does not crash, and there are no crash reports. In other respects this is similar to a previous post by 'eladopoulos' on 4/30/22, 8:17 AM (https://support.mozilla.org/en-US/questions/1375635).

Using Safe mode makes no difference. I had set browser.download.improvements_to_download_panel to False, but reseting to True makes no difference. Thanks in advance.

I have used Firefox since forever, was a Netscape user in the past

But for about 3 months Firefox simply is no good anymore\

It is more and more sites I can not access with Firefox and have to use Edge instead.

Last example, just now

https://www.cibc.com/en/journeys/new-to-canada.html

See screens attached

This is just one example, many other sites simply do not open, or open properly, in Firefox

WHAT IS HAPPENING?

Thank you

I keep several email tabs open that have topics I am currently working on with clients. Recently they have been turning blank, so I have no idea what they are--I feel I have lost info that I need to do business. Why do they turn blank? I need this fixed ASAP!

I'm trying to perform the clean reinstall for Firefox on my computer. But, I see the instructions for the uninstall, Delete the Firefox installation folder, which is located in one of these locations, by default:

   Windows: (Note: Check both folders.)
       C:\Program Files\Mozilla Firefox
       C:\Program Files (x86)\Mozilla Firefox 

Being I'm not computer wizard I had trouble finding the location of such folder. But when I accessed my program list in my windows program list I see a program named Mozilla maintenance service. When I click on that I see a format/window to "uninstall C:\Program Files (x86)\Mozilla Maintenance Service\." Is this the program/folder I need to uninstall to complete the proper instructions I need to perform a clean install? If so, when I delete it I then reinstall Firefox once again after the uninstall procedure? Is performing the uninstall procedure going to screw up my Firefox browser and my many bookmarks I have accumulated over the years? Can someone please help and explain? Thank you.

Hey folks,

i am facing issue with high CPU usage on firefox in completely different process other as visible in task manager than my actual process for firefox. is there something wrong with firefox or my system.

This separate process uses more than 60% of my CPU (AMD Ryzen 5 4600). If I close that process in the task manager nothing happens to my current firefox process and i can use firefox normally.

But everytime this separate process starts my system fans ramp up and CPU temps peaks to 70 degrees celsius. and i have to end that process to make it run normally. Thats a quite annoying process to do every time.

I am able to recreate this separate process by:

1. 1. Plug my system for charging
2. 2. I was working offline and connect to internet

both the times the separate process automatically starts and uses very high amount of CPU. I even left my system for 2 hours to keep that process running and complete whatever it was doing. but nothing happend. It continued to run for 2 hours also.

Please find a solution for this. I have already tried solutions provided in the forum:

• Restarting firefox
• Refreshing Firefox
• Enabling hardware accleration
• Clearing some user profile data
• Completely uninstalling firefox and deleting the residual files then reinstalling etc.

but nothing worked.

When using Firefox I am getting PR_CONNECT_RESET_ERROR in any tab I open or refresh. Error does not happen in Chrome or Edge. Running Windows 10, Firefox 121, Kaspersky This started happening today.

I fully uninstalled Firefox and then reinstalled again, but issue hasn't been resolved. Also, I disabled Kaspersky, but issue hasn't been resolved.

Pls advice what to do, as I can not use Firefox any more.

For the past few days, when I try to log on to PlayStation on Firefox, the sign-in page sits on a loading swirl after inputting email. There's a clear memory leak shown on Task Manager. The menu bar's right-click doesn't draw properly. FF can't be closed and needs to be terminated. The only extension I have is uBlock Origin disabled for this site.

This website works on Edge.

Attached is the broken menu from right-clicking the menu bar.

Start new Windows session. Start Thunderbird and works OK. Shut Thunderbird down and try to re-start during same Windows session and it will not launch. Reboot Windows and try to start Thunderbird and works OK. Alternatively, going into Task Manager there will be a number of Thunderbird processes running. If I manually end them all (while Thunderbird is NOT active) then I can restart as normal too. This all began with 124.0 Beta 1. Never had the issue prior.

Also, Thunderbird crashes if restarting within the app. By this I mean clicking the X it appears to close (excepting those persistent processes running) but "Restart Thunderbird" such as to launch Troubleshooting mode or from the "Restart to update Thunderbird" config crashes the app with 100% consistency.

YouTube videos on Firefox getting slower and jerky. After refreshing Firefox (Settings -> Help -> More troubleshooting information -> Refresh Firefox), it is OK, but only for a short while. Then the problem starts again. Same YouTube videos are running fine with Chrome at the same time.

Running Windows 11 Pro (Clean windows setup not long ago and the issue was there from the beginning.) German Language Firefox 116.0.2 Build ID 20230805021307 Intel CPU i7-1360P, 16 GB RAM, 1TB M.2 SSD

Would really appreciate a solution for the issue because I really like Firefox!

Hi, My inbox shows that there are messages in the inbox but it does not display them. Any action on the inbox gives the msg. "The current operation on "inbox" did not succeed. The mail server for account (my Optimum acct) responded: IMAP4 server terminated connection." I can see the messages on the Optimum website.

I forwarded my incoming mail to a Gmail account and can see the incoming msgs there. Also as can see them on my Apple phone.

Upgraded to latest version of Thunderbird. No help. Other folders seem okay. When I look at the ImapMail folder, I see the msf file for INBOX but I do not see a file for the inbox emails.

I am on Windows 11 and use MS Defender for security

Please help - Thunderbird is my workhorse and contains all my important files. Thank you! Carol

I have a very small Tablet computer and Thunderbird is really bogged down on it. The tablet has a 32 bit processor, 1G RAM, 64G SD drive. (1) When I run TB I get many "not responding" messages from Windows. (2) Maybe 1/2 the time, if I "delete" a message the screen will freeze on the message. The message is removed from the inbox list. I have to click "X" to get rid of that screen. (3) Get Messages no longer works. When I click it, nothing happens. The status bar at the bottom remains on the last information displayed. I found that if I use View, Folders, All, I can bump TB to get messages. (Normally I use Unified Folders) The status bar will display each of the accounts it is checking and any new messages will appear. These things have been happening through many many versions of TB. Although #3 seemed fixed a few weeks ago but has returned. Same for #2.

I looked at the disk space that TB is using and found that TB is using over 10GB. See attached. I don't know why it is so large. I don't need to store any messages on this computer. I have a desktop that is my "base station" where I want to save all (but deleted) messages.

I don't know if this large amount of TB space is contributing to the problem. Any help would be appreciated.

Dear Thunderbird Technical Support,

I hope this email finds you well. I am reaching out to seek assistance with two recurring problems I have been experiencing while using Thunderbird as my email client. I have encountered connection timeout issues with both Gmail and our company's website servers, as well as SMTP failures when attempting to send emails. I would greatly appreciate your guidance and support in resolving these matters.

Here are the specific details regarding my setup and configurations:

SMTP Configuration: Server Name: smtp.gmail.com Port: 465 Connection Security: SSL/TLS Authentication Method: OAuth2

While using Thunderbird, I am connected to the internet through VPN V2RAYN. However, despite configuring the SMTP settings as provided above, I am facing difficulties with both connection timeouts and failures when attempting to send emails.

I kindly request your assistance in troubleshooting these issues and providing any necessary steps or recommendations to resolve them. It is crucial for me to have a reliable email client, as efficient communication is essential for my work.

If you require any additional information or logs, please let me know, and I will be more than happy to provide them promptly. I understand that resolving these technical issues may require your expertise, and I appreciate your time and attention to this matter.

Thank you for your assistance. I look forward to your prompt response and guidance.

Best regards,

Hello, I upgraded this morning TB to the latest version 102.13.0 but my account on office 365 is not working properly. I cannot forward messages anymore and the messages that I send have no content.

I am using Exquilla for Microsoft exchange and there is something definitely wrong since the upgrade was done.

Can you support urgently?

Best regards,

Fadi
