Until today it worked fine. But now whenever I try to login to Xfinity I get You don't have permission to access "http://login.xfinity.com/login" on this server. It works fine on Chrome and Edge. I have disabled my add-ons. I have cleared cache, cookies, etc. I have rebooted. I have turned off firewall. I have checked my DNS. I have changed the DNS protection to OFF in Firefox. I have checked my proxy setting (I have no proxy). I have reinstalled Firefox. Etc. Etc. Nothing works. The fact that it works on Chrome and Edge, that it has worked everyday until today gets me confused. I also tried using my mobile phone as a hot spot to make sure it wasn't related to my Internet connection or IP address. Anyone have any ideas?

Dear community, I have recently updated my Thinkpad from kubuntu 22.04 to 24.04, which included an update of thunderbird to version 128.1.0esr (and a switch to a snap package).

However, when I type into the quick filter bar, (i) the whole thunderbird GUI freezes until the filter was applied to my several thousand emails, (ii) which also seems to take much longer than before. Before the update, the filter took maybe ~0.5 seconds or less, it now takes ~4 seconds. A lot for just a few thousand emails. Btw, the same happens if I empty the quick filter field. Just that it seems to take now even longer until it shows all of my emails.

I don't know if anyone can help. I feel more this could be something for a bug report?

Thanks a lot in advance, Matthias

Hi, I'm using Linux Mint 22, Firefox 129.0 (64-bit). Browser is hanging after approximately 4 hours. Not sure if this is a Firefox issue, but this is where I'm starting the troubleshooting process. My suspects are (1) the browser, (2) NVIDIA drivers (3) the new Linux Mint kernel or possibly (4) a mix of the above. This was a fresh install with default options on (Wilma). Using the latest graphics drivers for GeForceRTX 2060, driver version 555.58.02, went down to native drivers, no change. Honestly, this one has me baffled. Been troubleshooting this for 3 days. It feels like a memory leak. Nothing on the crash reports. First, browser will hang, then mouse and keyboard. Hard reboot is the only option. Any help would be appreciated.

Sometimes when I consign an email to the trash and then need to re-read it later, it's turned into gibberish. A tiny fraction of a recent is below. I've used the "repair text encoding" feature, without any result. If I scroll further down in the gibberish, there are links that weren't in the original email and would have had to be sucked in from other emails in trash, which I just don't get. I can go back to the email on my phone, but on my desktop, they are hopelessly jumbled. What causes this and how can I stop it? Thanks!

I am not the one using Firefox for iOS; my sister is. I am not looking for an actual fix at this point, I just want to know if anyone else is having the problem.

My sister was having no problem logging into Chase with her 8th gen iPad until about a week ago (my apologies, I don't know the exact day). She tried to log in, and the Web site took her to the system requirements page.

The weird thing is, her system was fine according to their list. But she updated to the latest iOS (18-something) and then the latest Firefox for iOS 129.0.1 (she doesn't like .0 versions and always waits for .0.1).

She got the same error.

Chase insists that the problem is hers. Personally, I don't trust a corporation that big farther than I can throw their combined offices on the planet. Is anyone else getting this problem?

Again, I am not looking for a fix at the moment, just looking to find out if the problem really is in her set.

Thank you.

I migrated to a new computer with Windows 11 and to the latest TB nebula. I copied the profile folders to the new system and it imported 20 years of email correctly. BUT every connections seems to hang and eventually times out. It almost looks like TB blocked by a firewall. Even checking for updates eventually times out. HOWEVER everything works fine in troubleshooting mode.

I have no add-ons installed. I have no VPNs or additional firewalls. Disabling Windows firewall entirely doesn't change anything. I tried "Make the changes and restart" with no success. I added thunderbird.exe to the exceptions to the windows firewall and even added a rule. I tried uninstalling and reinstalling.

Is there any setting related to the connection that would be different in troubleshoot mode? Apparently nobody has ever experienced this problem, I feel like I'm going insane.

Ever since I've been upgraded to Thunderbird 128, I've been experiencing constant hangs. I'm running the latest versions of Thunderbird and Windows 10. My antivirus software is Windows Security.

This issue seems to be most acute whenever Thunderbird checks for new messages. Thunderbird's CPU usage jumps to between 25 and 30%, and memory and disk usage also skyrocket. Thunderbird freezes completely, and everything other program that's running at the time is slowed to a crawl for several minutes minutes. Troubleshoot Mode doesn't help.

Any suggestions?

Thanks.

I use Mozilla Firefox for work. Part of my work requires I use the GlobalProtect VPN client. When I log on to the VPN, everything appears to be fine. The problem arises when I log out of the VPN client, such as needing to switch to a different VPN.

When I log out of the VPN client, Mozilla slows down massively. I get the following errors when trying to access websites.

PR_END_OF_FILE Timeout

I thought it was a DNS issue, but the change I made previously did not prove to be a reliable fix, and I do not actually know the root cause of what is happening. Firefox returns to normal ONLY after a full computer restart. At this point I am considering switching browsers as, despite Firefox's functionality, it is starting to interfere with my work.

I have used other VPNs, such as Fortigate VPN, and not encountered anything like this.

Any advice or guidance would be appreciated.

Hi, After migrating email server, I am having problems synchronizing some IMAP accounts, but Thunderbird is unable to organize the emails and it corrupts the display. In Webmail it is normal and I have no problems accessing it. Coincidence or not, but the emails that are causing this problem are emails that have more than 80Gb. What I did to see if it would improve, was to divide the emails into folders by year, to reduce the size of the email occupancy, but it didn't work. At first, right when I implemented it, they asked to modify this configuration:

Edit → Preferences → Advanced → General → Configuration Editor. Follow the procedure: Locate a key called: mailnews.customDBHeaders Change it to: Received After that restart the application --> Right click on the folder and go to Properties --> Repair Folder

This worked for a few days, but then it started having problems and even repairing the folder, but it didn't help. What they told me was an issue with Thunderbird reading email data on their server, but the problem continued. They kind of "washed" their hands, since it's ok on their server and asked to test it on another email client. Has anyone experienced this problem? Attached is an image of what the email looks like, there are several with the data that I asked to repair, but empty. I've already updated to the latest version of Thunderbird, but it's still like this.

Thunderbird v102.15.1 is very slow to open in Win 7. Yes, I know Win 7 is obsolete, but I must continue on with it for a while longer.

When I open Win7 each morning and then try to open TB there is a very long delay before I get the TB prompt to select a profile, the then a long delay for TB to actually open, and then a long delay before I can actually select an email account to read. (I have 20+ accounts). I routinely open Windows Task Manager to see what is going on, and close unneeded programs.

In the past with older versions of TB back to 60.9.1, I recall seeing Thunderbird Profile Manager in list and changed the Priority from Normal to High or sometimes Realtime and that seemed to help. But with recent TB versions, the Task Manager has added several other items besides the Thunderbird Profile Manager - very long items that include something like "child ID1, child ID2 and child ID3." I have tried changing the Priorities of each of these to High or Realtime but am not sure that helps.

Eventually TB starts but when I go to my main email account and try to read Inbox with up to 120 emails each day, messages are very slow to load and I often get "Not Responding" for a long delay.

What is the solution to this problem? I move older messages from Inbox to local folders, delete Junk and Trash each day, etc.

I tried to do an import of a backup profile that was very large, greater than 3 GB. System says this file is too big to recover. Error console is as follows:

I am not able to search names in my individual Address Books. I have to scroll down the Contact List to find the name. How can I fix the Search feature in my Address Books?

It seems since the latest update to FireFox (129.0) I am no longer able to pick a search engine to use, I can click on DuckDuckGo or any other choice for a search and no search engine will come up?? Thank You for any help or suggestions.

Since 128.0 was installed outlook.office.com/mail has stopped working. (Windows 11)

My mail account has numerous shared groups. However these now fail to load with a messgae "Cannot load folders for "xxxxxxxxx" Decoding failed.

Additionally, while I can see new mails in the list (under focused and Other), the previews are all blank.

I do not get this error in Edge or Chrome in Windows.

I am unable to use my bill pay with my bank using Firefox browser. However, I am able to use it logging on with Microsoft Edge. What has changed with Firefox recently? This has only become a problem as of today.

When I create a 'saved search' in Thunderbird by using the File>New>Saved Search... menu the "folder" is created but is empty even if the search was valid. After restarting TB the saved search "folder" disappears.

How do I fix this?

Yesterday Thunderbird worked. Today every time I download a message I have time for a coffee and watch the blue circle of death. The message does come up after a while but the program is so slow and unstable that it's not really usable. This issue seems to come and go over the last few weeks?
