I've been using Firefox for a couple months now, and I just ran into this problem today with English text nearby Japanese text: https://files.catbox.moe/diw4y3.png

• It's not affecting Japanese text
• It's not exclusive to Japanese websites (it's present in one email in gmail, but not all of them)
• I haven't seen it on any Japanese websites
• It's also present in some add-ons that generate text (Checker Plus for Gmail, Yomichan)
• Turning off all add-ons doesn't fix it, but opening the page in a private window does fix it

Firefox 155.0.1 (64-bit), Windows 11 Pro

Hello everyone,

Environment: Thunderbird 155.0 Windows 11 Pro, Surfshark VPN and Bitdefender Total Yahoo.ca POP3 account transaction@notice.aliexpress.com promotion@aliexpress.com

The Symptoms: Thunderbird stopped downloading emails from my yahoo.ca account with the message "Downloading message 1 of xx" where xx was increasing from one day to the next.

What I Have Tried: I disabled the antivirus and VPN without any result. I deleted the file global-messages-db.sqlite without any result. I entered the web interface in my yahoo.ca account and I saw that after the last message downloaded in Thunderbird there was a message from <transaction@notice.aliexpress.com>. I deleted the message from <transaction@notice.aliexpress.com>, restarted thunderbird and it started downloading messages until the next email from <transaction@notice.aliexpress.com>. I repeated the procedure several times with the same results: Thunderbird downloads any message except messages from <transaction@notice.aliexpress.com>. Other messages from aliexpress.com (e.g. promotion@aliexpress.com) were downloaded without any problems. The message download is blocked only when an email from <transaction@notice.aliexpress.com> is reached.

I searched for solutions on the internet but I didn't find anything.

i can't open my pargon system.Here's the error message:

Could you please help solve this.

Many thanks. Regards. Fei

Have used Thunderbird for years and never had this issue before. Just upgraded to Thunderbird 115.18.0 esr and my calendar is now blank. Did the upgrade erase the data or is a pointer off somewhere? Can I get my calendar back?

When I want to install a theme for my firefox there is an error which says:"Installation aborted because the add-on appears to be corrupt." And because of this error I cannot install any theme. Please help. Thank you...

Los videos de YouTube no se reproducen correctamente en Firefox. Algunos videos no cargan o se quedan congelados y no puedo verlos normalmente. Ya intenté actualizar la página, pero el problema continúa. Quisiera saber cómo puedo solucionarlo.

Which dictionary are we using? (Or are we allowing English spelling to be supplanted with American or other spelling?)

Whereas in MS Windows I can choose UK English or one of the many different forms of English in use elsewhere, I'm noting that in Mozilla/Firefox I get the typical warning under a spelling that does not equate with the spelling used in the current dictionary and yet these spellings are not UK English...

Even I choose UK English as my default dictionary the spelling of "colour", "neighbour", aluminium, still give this indicator.

Greetings,

I perform a daily thumb drive backup of Thunderbird in the event that my PC crashes (which it has) so I don't loose emails and contacts. I'm aware of two methods to do this. I've tried both, and one method saves more file folders than the other. My question is: Which is correct to use?

One method is described here: https://support.mozilla.org/en-US/kb/thunderbird-export The other method is accessed from the main page of Thunderbird: Import/Export > Backup, select OK and then the location and folder where you want the data to be transferred.

The first method captures four main folders and other files listed below them. The second method captures ten folders and all of the same files as in the first method.

Because they are different, I'm unsure of which to use and, additionally, why would two methods be offered?

Thank you in advance for your comments and advice.

I have a new (to me) Microsoft Surface pc with an ARM processor. After a very recent update to Windows 11,my entire Thunderbird installation has disappeared and I have been forced to use the Web to access my emails from Posteo.de Can you assist me please?
