I installed Thunderbird (T-bird), and on the "Set Up Your Existing Email Address" tab, I entered my Xfinity e-mail address/password and clicked on "Continue". T-Bird is able to find the proper configuration in the Mozilla ISP database. I clicked the IMAP radio button and then "Done". That opens a popup window with the heading "Enter credentials for <my-email-address> on imap.comcast.net, but the window never prompts for anything (a prompt for my Xfinity password is what I expected). Instead I just get a message headlined "Unable to connect", with the subtitle "The connection was refused when attempting to contact localhost". This is followed by three suggestions for why that might be the case. I verified that: 1. The Xfinity site is NOT "temporarily unavailable" - I can log into Xfinity directly and see my messages. 2. My computer's network connection is operational since I can load any website at will. 3. I do have Windows firewall enabled, and I suspect that is root of the problem. How can I permit T-Bird to access the web??? Thanks.

For the last 2.5 months, the quick filter function has been painfully slow, taking up to a few minutes to deliver all of the results. We were on v128, but read that this was a known issue, to be fixed in release 131(?). We just upgraded to 139.0.2 and the issue is still present. We have ~12K messages and we're running Win64 on a Surface Pro 10.

Should we downgrade? If so, which version?

Thanks

Hi every one, hope someone can help me.

I have a special mail account: contact@c-serp.fr

The incoming server is managed by my Synology NAS server (MailPlus server), the identifiers are Incoming server : - protocol: imap - hostname: c-serp.fr - Port: 993 - Connection security: SSL - authentication method: normal password - username: contact@c-serp.fr - Pwd: -------------------

Outgoing server : - protocol: smtp - host name: smtp-relay.brevo.com - Port: 587 - Connection security: STARTSSL - authentication method: normal password - username: XXXXXXXXXXXXXXXX@smtp-brevo.com - Pwd: --------------------

All these settings work perfectly on outlook 2021. But on Thunderbird, nothing works.

Why is this? Any suggestions are welcome

Ucan.

Translated with DeepL.com (free version)I have an email account

Sort of continuing from https://support.mozilla.org/en-US/questions/1423702

Now trying 139.0.2 on a old laptop the subfolders are not mixed in the root anymore, but when opening TB, the subfolders are only partially listed. The listing changes every time.

TB then creates/downloads the missing ones/the subfolder structure but then leaves them all displayed as open/uncollapsed, which is a massive folder tree to navigate down. Takes ages and is a total pita.

We could even live with being able to collapse all the folders in one action, but there is no command for that.

I read elsewhere it may be a problem with OAuth so changed to app password, no difference.

Maybe it's the very large quantity of subfolders...

I note that the profile folder is the same size when TB is opened or closed....indicates that TB has the folders downloaded but needs to sync to display them?? No idea really.

But, we've been avoiding updating for a year and a half, need a solution or another client.

Thanks for any help.

Cleared history etc. and the system will not open up the link I need to see my mothers blood culture results? Her is the link to the website https://patient.labcorp.com/landing

I have sugarcrm running via firefox. I show a phone icon for click to call next to phone numbers but click does not initiate the call. I have to highlight the phone, right click and send it to the dialer.

Is this a settings issue?

I get an unsupported browser message when trying to share items on facebook marketplace, it tells me to use a browser that supports end to end encryption, which I thought Firefox did anyway. This seems to occur on my iPad rather than my iMac! Any help would be appreciated

I saw my same issue described in an archived thread "Several users have reported connection issues with Google sites including YouTube. This has been linked to the "zero round trip resumption" feature. That is intended to speed up website connections, but there seems to be some kind of compatibility issue. Currently, there is only a hidden way to disable this and see whether it helps".

I tried the method given (going to about:config and turning security.tls.enable_0rtt_data to false) but it did not work.

I tried uninstalling and reinstalling, but I accidentally dragged the Firefox in the installer directly onto my dock (on Mac) and that Firefox was working perfectly fine. But I noticed there was "Firefox" drive running on my system. To fix it, I realized I had to drag the Firefox in the installer into my applications folder and run that Firefox. So I did so, and ejected the Firefox drive.

Using the new Firefox that was actually installed in my Applications, I am now stuck with the same problem of Google sites not being accessible.

I am sitting in hospital with a weird problem. The connection is open and thus not secure. I have successfully connected my 2 android devices, however my Windows Asus laptop is being barred by firefox. I only run firefox. It is a dead end because firefox refuses to allow me to access the net at all. So now I have to get my wife to go and download chrome and see whether that will work. Why can I not override as u understand the risks I also use Norton 360 with its VPN.

on the game 'my little farmies' by upjer, when I go to fullscreen, a blue haze covers the entire area making it difficult to discern colours. I have cleared cookies and reloaded the game, switched the pc off and on again. nothing makes it go away. does anyone have any ideas. i have asked upjers but they say it is a firefox problem. many thanks for any forthcoming suggestions.

How do I resolve this issue

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

I was in C-Panel looking to delete emails as the serve is full but wanted to see the emails before I delete them. The 38000 or so of emails had downloaded and I began the process of selecting and deleting when I got the message that this page is not redirecting properly. was never a problem in the past but is now why?????? and how do I resolve as I cannot received anymore emails until i clerar out the server?

I just installed Thunderbird 139.0.2 on Mac OS Ventura 13.7.6 and set up my Exchange account. When I get the messages I do get a list of the messages.BUT when I click on a message, the message does not come up in the message pane. When I double click on a message a new empty pane opens. I can't see my messages. What am I doing wrong?

Hi,

I use firefox nightly as my everyday driver for WEB. So far I was very satisfied with the performance and mostly with youtube videos and hardware decoding. I use a Nvidia 1060 (GP106) which supports VP09/AVC1/H265 decoding.

The problem started only recently after some updates of the Firefox when I noticed that VP09 isn't hardware accelerated anymore. They way I test is using the Windows 11 task manager/Performance/GPU/Video decode.

At the same time, the stable Firefox has no issues with VP09 HW decoding. The same is valid for any other browser I tested. So the problem is isolated to the nightly.

I downloaded and ran mozregression GUI which indeed showed me that some nightly version before the VP09 worked just fine. I tested using the dates option of the tool.

This is the push_log URL from my test.

Thanks in advance for your help

Whilst viewing news stories in Google, I keep getting pages that do not load, so I go to settings – apps- Firefox, scroll down to memory and clear the cache. I go bag to Google new click the link and most of the time I am taken to the page and can read the article (but not every time). But the page not loading happens frequently and it is becoming a pain having to clear the cache over and over again. Is there a shortcut I can use to reach Firefox memory or is there a way of stopping Firefox to clear the cache as it is created.

I have downloaded Duolingo on my Windows 11 laptop. When I try to run it, it says that it can not open it because it can't find Microsoft Edge. This is the latest version of the app. I can't find anywhere to change the Duolingo default browser. I have Firefox set as MY default browser in windows settings. I also have AVG Secure Browser installed on my laptop but seldom use it. I donot have MS Edge installed on any of my computers. Can anyone help me find a solution to this problem? What other information do you need?

Haven't changed any settings. On two accounts, both hosted at heart internet, today I've started getting Certificate errors - check your settings in android notifications. Mails appear in sent but are not going out, no incoming mail.

Another account with the same settings and host is still working fine on bluemail.

I can't find any useful settings or diagnostics to check.

Other accounts using Hotmail are still fine.

Ideas?

My FF browser freezes, suddenly closes all tabs, expands fonts, etc etc All else in my system is normal. Should I just use the default MS Edge and be done with it?
