When I go into my email program it asks for a password over and over again. it doesn't matter what password I put in, nothing works. Thunderbird has tried to send codes, but they don't go through to my email program. I have used my iPad with a different email address to check some things and go to Shaw Webmail to retrieve my emails. I need it to work as I have lots of files on there that I use often with a volunteer organization among others.

Several days ago Firefox deleted all of my saved passwords. When I built up a new list of saved Passwords, they are all deleted and gone the next day. Why is Firefox doing this?

Today, I once again had to refresh Firefox Due to my eBay page being rehashed and not usable, but I forgot about my Facebook and after the refresh found I have now lost almost six months of chat history (most recent of which is very important to me), and I just can;t find a way to recover it. Please advise me what to do. Kind regards

I have never deleted so many emails at one time, around 500. Did I exceed the limits of Thunderbird? I cannot log on. Cannot see new emails. I have been on emailsrvr.com and did verify my passwords. Thank You

Hello everyone,

I keep having the issue that on some websites, a whole list of cross-site cookies is displayed when i click the icon to the left of the address bar. "These parties can use cross-site cookies and site data while you are on this site."

Especially Google (I am not logged into a Google account) lists many different sites here. I can then click on "Allowed X" - but after a few days, the entry appears again without me being asked!

Under "Privacy & Security" I am using the Standard level. It says there: "Firefox blocks the following: (...) Cross-site cookies in all windows (...)" So why are some still being allowed? How can I generally prohibit them except for those I manually allow? The five levels for cookie handling under "Custom" are unfortunately not very self-explanatory, and I can’t find any whitelist option there either.

Thanks for any advice! Best regards, Martin

Hi I keep getting the message "Unable to connect to your IMAP server". I have reduced the number of 'server connections to cache' from the default 5 down to 1. Thanks

I can receive mail fine. Cannot send mail on gmx.co.uk acct, but gmx.net works on oauth2. But oauth2 is missing on gmx.co.uk It's just not on the pulldown. I tried a new thunderbird acct for gmx.co.uk but oauth2 is still missing.

Can get(POP3), but can not send emails to a newly created personal outlook.com account.

the following error occurs when trying to send mail: Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)

all my setting are correct per thunderbird and microsoft:

  (smtp-mail.outlook.com, port 587,  STARTTLS, OAUTH2, xxxxx@outlook.com)

thunderbird error log file contains the following: . . . mailnews.smtp: S: 535 5.7.139 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Mailbox.

Based on my understanding its seems thunderbird is using SMTP AUTH instead of OAUTH2 as required for newer personal outlook.com accounts. Is my assessment correct? If so, is there a fix?

What seems like ages ago Firefox stopped displaying bookmarks I addition it would not add new bookmarks nor restore the existing ones. I've gone through all of the corrective procedures listed on and off but nothing works. As a final attempt I deleted the program and reinstalled it. No change. It seems to me that perhaps a missing file from another program or system is missing. Maybe!

I have been using an alternate system for some time. When installed it had no problem finding all of the Firefox bookmarks and placed them on the menu bar as "Firefox Bookmarks". I have no issues with using them but all new ones are stored in the current browser. Thus the new ones do not go into the folders previously set up. I've avoided moving them manually to the new system due to the volume but I am ready to bite the bullet.

I prefer Firefox but it's just not working.

Can anyone save Firefox for me.

Hi,

I’m experiencing an issue with my website Fixit Home ([[Interior design and fitout company|https://fixithome.ae]]) ). Certain pages and elements, including images, navigation, and layout, are not rendering correctly in Firefox, even though they work fine in other browsers like Chrome and Edge.

I’ve checked:

The website code is valid and loads without errors in other browsers

SSL certificate is active and pages are secure

JavaScript and CSS files are loading correctly

Could this be a Firefox-specific compatibility issue, or something related to caching, security settings, or mixed content? I’d appreciate guidance on how to debug and fix this problem so my site works consistently for Firefox users.

Thank you!

В полученном письме с почты THE AHMAD TEA STORIES d.gorshunova@sdc-foods.ru, у меня не отображаются картинки - показывает значок разбитого изображения в верхнем левом углу. От других адресатов картинки загружаются. И в других браузерах все картинки с этой почты показывает. Пожалуйста, почините!

When I use picture-in-picture for any video, all of my firefox browser windows go unresponsive. I can move the cursor around, but it won't allow me to click on anything. The only way to stop it is to open a brand new window which makes it responsive again and then close out of the PIP video. Sometimes it lets me go back to using the browser as normal, and other times it causes all firefox windows to crash. I'm using Windows 10. This issue only began happening about 10-ish days ago.

The Crash Report IDs are: bp-42f92617-671a-4e30-9d32-e1def0260302 bp-64cb35b0-5ab7-4b9d-8a80-7d2470260302

I've checked and double check as well has changed the outgoing settings from 465 to 587. Nothing works. Help148.0 Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-h2p-555627.sys.comcast.net resomta-h2p-555627.sys.comcast.net Excessive failed authentication, ESMTP server temporarily not available.
