Since the latest upgrade to 115.10.1 (64-bit) I have an issue about running Thunderbird.

From a clean Windows 11 start up it is OK but then if I then Exit and then try to run the bird again it does not start.

Digging around I discovered using Task Manager, a number of Thunderbird processes run after I had Exited. See attached.

Any thoughts?

In recent attempts to join a few webinars I am now getting more and more "TLS Errors." I have noticed that many of the solutions to this problem involve actions that do not solve the problem but create larger issues. Do you have a solution that works safely? I am forced to use Windows 7 unfortunately due to work systems and a long story. I think this is my primary problem but I have to keep using it until the bitter end with this PC.

I appreciate your kind help. Thanks, Clay

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?

Ta.

Every few hours, maybe 4 times a day, XULRunner appears and tabs me out of everything. It says "This profile was last used with a newer version of this application. Please create a new profile."

There isn't a 'create new profile' button. I already made a new profile as well, but it did not fix the problem.

I recently changed to the newest ESR, 115.10.0esr, to fix streaming issues.

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.

About 2 weeks ago, Thunderbird stopped sending emails. I spent a couple of hours on the phone with tech support but was unable to correct the issue. Changed all of the settings several times, SMTP server, port, security and authentication without success. Tech support suggested using their server but that's a pain. Attached are pictures of the error messages. Thanks.

Hi,

Just updated to TB 115.10.1 and right on update it now fails to show the most recent emails in the inbox, They are there as I can scroll up to them but it no longer does that on it's own when opening and downloading the latest.

Any suggestions to get it back to normal operating condition?

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 am using Thunderbird 115.10.1 on Windows 11. T keeps deleting my saved passwords. T takes a very long time to load. There are no saved passwords and I enter them all with the options to save. I check the passwords in Settings and they are all there correctly. When I next run Thunderbird it may or may not have them still saved. I check the Settings and they have gone; so I enter them again and they are saved OK. But then they are deleted some time later. I cannot see any pattern in the failure. I wonder if there is a problem with the outgoing server setttings. All the passwords are lost whether imap, pop (Ionos), hotmail or yahoo. Is there a way to clear out my profile or is this a problem with this T release. it did not happen until about 1-2 months ago. My profile is on a local NAS. Generally T seems to be quite unstable ; I get Not Responding too often.. Thanks

I get this message from Thunderbird on my desktop computer on app start up: ]Warning: Potential Security Risk Ahead

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.

This started suddenly about a week ago.

I have Thunderbird on laptop that works fine.

How can fix this?

I have read the thread for this similar problems, tried all the suggestions but I'm Still experiencing videos not staying full-screen. Is there any other solution to it? This has started since yesterday but everything was fine before then.

Other than just the setup, how do I get Thunderbird to use "POP" rather than "IMAP" protocol for email? Until March of this year, I had Thunderbird setup as a "POP" client for email downloads from Frontier. And, then Frontier moved all of their email services to Yahoo and in the process, my Thunderbird wound up using "imap.mail.yahoo.com" instead of "pop3.frontier.com". I don't want IMAP - I want POP. So, I tried changing that in Thunderbird setup to "pop.mail.yahoo.com", but it does not respond.

Hi there, I have noticed that my Win11 Asus laptop is always short on RAM (16GB available), with Firefox taking up a significant amount even with only a few tabs open.

As you can see by the attached image, when I go to 'about:processes' it shows that GPU processes alone are taking up nearly 1GB of memory, with the only tab running being the 'about' page. I only have 6 extensions (uBlock Origin, Zotero, Containers etc) none of which are meant to be RAM intensive.

What are these GPU processes that are running, and how can I reduce the memory used by them?

Thank you.

looks like a problem with Firefox as no problem when using a different browser e.g. Opera. Also cannot log onto Nextdoor.co.uk using Facebook to log on. Again works fine on Opera

Any links from rcsearch.ru to aliexpress is broken in firefox, but works in another browsers. For example click any aliexpress link here rcsearch.ru/-c48920.

Posted this before, got no answers, not even a "no, there's no cure for that." Hoping for better this time.... My inbox suffers from disappearing email sometimes, and using the properties>repair cure works okay as far as I can tell (if someone emails me and doesn't ask about it later, how would I know?). But it has happened frequently enough, half a dozen times a month or more, that I do the repair by default pretty much every day just to be safe. That's easy but still a pain. Does nobody in MozillaWorld know a more permanent solution to free me from my constant missed mail paranoia? As I said, a reasonably authoritative "No, there isn't" is perfectly fine and much better than radio silence. Regards!

Whenever I go to youtube, it fails to work and leaves an error in the console similar to

Uncaught Error: Constructing ytd-app: [Exception... "File error: Corrupted" nsresult: "0x8052000b (NS_ERROR_FILE_CORRUPTED)" location: "JS frame :: https://www.youtube.com/s/desktop/050e6796/jsbin/desktop_polymer_enable_poly_si.vflset/desktop_polymer_enable_poly_si.js :: kCb :: line 9877" data: no]

I've determined that I can fix the problem by deleting my Firefox profile. I'd prefer to avoid this since there's a lot of useful history there. Is there a more targeted fix the problem I'm seeing?
