I have been using Mozilla Thunderbird for decades and they have even contributed a small amount of money to Thunderbird periodically. Just within the last two or three days all of a sudden I have been unable to send emails with my phone. I receive emails, but I do not send them. So I opened up a laptop where I did not have Thunderbird and set it up properly through Spectrum using the incoming and outgoing servers as mail.twc.com. and yes, just like on my phone. I continue to receive new emails, but even with the laptop I was unable to send an email. I received the message"send message error sending a message failed. The message could not be sent because the connection to outgoing server smtp mail.twc.com was lost in the middle of the transaction. Try again."I contacted Spectrum twice and both times they had me try to send a message through their Web server spectrum.net and that message did go through. Of course then their response is that this has to be a problem with the third-party app meaning Mozilla Thunderbird, and they can’t help with that at all. I sure would appreciate some help because I hate to walk away from Thunderbird as well as change my email address after all of these decades.

Spectrum recently updated their email systems and Firefox can no longer be used to check Spectrum webmail email accounts. I used to be able to go directly to the webmail but now they make you log into your Spectrum account to get to the email accounts and there is something about Firefox that is not up to their security standards. I am running Windows 7 with the latest Firefox that will work in 7. I am also running the Brave browser on Windows 7 and that works with the new Spectrum system. I prefer using Firefox over Brave so could you please correct whatever deficiency exists in Firefox to make it compatible with Spectrum webmail?

FYI, Firefox on my Windows 10 machine has the same issue.

I just had a firefox tab with a pop up asking me to try ai features... my options were "yes" or "maybe later". How do I stop the slop sales? I want ZERO pop ups... from Mozilla or anyone else! I didnt see settings that would disable mozilla sales pop ups - is there some way to turn these off permanently? I have already turned off the ai features. Really appreciate any suggestions!

On some websites Firefox blocks entry of texts in text fields manifested in 2 ways: keyboard in Android pops but no text is entered when typing, or no keyboard pops. The tried refreshing pages, switching to desktop mode, clearing browsing data nothing works. Attempting to report this to a site:https://ambientweather.net. Ultimately I had to download and install a different browser to access the site. I was already logged into the site and other field changes were correctly implemented. On pages with 2 search fields, one site-wide and one in my search context, both fields failed When switching to desktop version, I noticed a typical cookie notice which I hoped was taking the focus away from the other fields but closing that notice did not resolve the problem.

While I assume a design implementation error by sites, this may be related to the ongoing memory conflicts one experiences when doing multiple searches on heavy video sites. As with the old Firefox Android, Firefox slows down and can't seem to dump all it's cache, apparently, to handle more input. in those cases a dump of most browsing data generally clears the problem, but didn't help here. I suspect an underlying Firefox cause because I've seen this over several random sites but with no clear pattern. I just revisited the site above and it works as designed now.

Consider this the equivalent to trying to use a PC without a keyboard, it's really a catastrophic fail.

Was researching cookie management techniques in GROC where AI suggested I go to the DevTools feature in the Firefox browser, go to the Application tab & expand cookies in the side toolbar. However, I’m unable to find DevTools

Hi! I had a firefox account when I worked for the law firm McCormick Barstow a few years ago. I haven't worked there for a few years. I just set up firefox on my personal computer, but am having problems changing my primary email from my work email (gina.axsom@mccormickbarstow.com) to my personal email (gaxsom@gmail.com). Can you help? I have no way of receiving any codes going to my old work email address which no longer exists. Thank you, Gina Axsom

1. How can I locate the FF version on my devices. I have Android 14 OS. Today (February 16) I located a versio 147.4 will be released. Is this automatically available for my devices or do I nèd to download. If so how.. Ðo I get notifications.

After an email update this morning, I went in to look at an old email and nothing was there. Checked all my other folders and they were all empty. How and/or can I get them back. Some were ones that I did not need to loose.

On outlook.com sign in with password does not work. It gives "Please retry with a different device or other authentication method to sign in." Works fine in edge.

I have an issue where the following operations with the "new" profile manager don't work: - setting up a new profile (about:newprofile in the new profile is just blank) (a new profile gets created though) - deleting a profile (about:newprofile is just blank) - editing any profile that is not the original profile (about:editprofile is just blank) (works with the original profile) - the select profile interface from the account or menu button is blank when opening it from any profile that is not the original profile

What works tho is calling about:profilemanager from any profile. From there any profile can be selected and switched to.

I'm using the Bazzite (Linux distro that is Fedora based). I'm fairly new to Linux so that could be a issue, the problem was there from the get-go though and since Firefox was preinstalled I don't believe I could've messed up much.

Firefox version is 147.0.4 Bazzite version is 43.20260211.0 (Kinoite)

Reboot doesn't fix these issues. Uninstalled Firefox with deleting user data, installed it again and same behavior appears again.

I also tried installing a Firefox fork (Waterfox). It had the same issues.

I would appreciate any help and would be willing to share more detailed date if it helps somebody help me.

The attached screenshots mostly show the UI that is not working as expected.
