Hi I am using TB 156.0 (64-bit) on Linux. I guess there was an update t TB and now when I reply or forward an email, the font size of the text is tiny. I also found that the font size for just viewing the body text of an email was tiny, but I was able to fix that. But for the font size in the body of a reply or forwarded email is tiny and I have gone thru all the settings for hours with no luck. Any help much appreciated.

I don't think I have the only decisive factor when switching from Chrome/Chromium-based browsers to Firefox - this is precisely the lack of support for web progressive applications. They are very convenient to use those sites that people use every day (YouTube, Reddit, Canva, Figma, GitHub, ProtonDB, etc.). I would really like you to add such mechanics from chromium-based browsers - this would change the situation very much when choosing "which browser to use?". I'm a Linux user, particularly Fedora, so I'm often helped by PWAs to use the same Instagram, Canva, Figma, GitHub, Reverso Context and others as if they were separate applications on a computer. This is much more convenient than keeping everything in tabs in the browser. Do not ignore my request, please! I would really like this mechanics in the browser

Today firefox changes theme and startpage everytime i startup, i have tried resync theme and settings, and turn off sync, and try remove startcash, and tried falesafe start, still the same.. and now i saw that firefox color addon was enabled by startup also.. should have something to do with the new update? The problem seems to be solved, perhaps it was firefox color being enabled by startup..

I used to be able to 'click' an email link,.. and the page would auto open in chrome,.. with a message at the top of the screen informing me this was happening. For some reason I must now use right button, and open in browser,.. in order to open the email link provided. s/w as follows:- Name Thunderbird Version 156.0 Build ID 20260915113124 Distribution ID ubuntu-snap-build User Agent Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:156.0) Gecko/20100101 Thunderbird/156.0 OS Linux 7.0.0-34-generic #34-Ubuntu SMP PREEMPT_DYNAMIC Wed Sep 2 14:29:37 UTC 2026 OS Theme Yaru-yellow / Adwaita Application Binary /snap/thunderbird/1259/usr/lib/thunderbird/thunderbird-bin

I have tried deleting the handler.json file but this does not fix or resolve the issue. My current Files & Attachments,.. has just a pdf entry,... set to preview in Thunderbird,.. and this duly open pdf's in a TB tab.

I have found the config editor settings,... for network.protocol-handler.external.http and network.protocol-handler.external.https and can verify they are set to true

But I still cannot just click on an email link,.. and have it open in my default browser.... Can anyone offer some options as to what i am doing looking where,.. wrong. Many Tx

Every time I need to launch privacy mode in the Android app, I can't find the button or a link. I don't use it that often, but it's important when I do need it. Each time I need it I spend a lot of wasted time looking for it. Ultimately I have to ask Google Gemini how to do it. 1) I don't want to keep asking AI how to do it. It ought to be easier to find. 2) I don't want a shortcut on my Android desktop with its limited, valuable real estate.

After thinking about it, it occurs to me that adding the ability to add a privacy mode shortcut to the toolbar might be simple for the developers and it would solve my problem. It's too bad I can't add more than one shortcut to the toolbar in Settings, but a privacy mode shortcut is the one I'd select... if only one were available. (sigh)

When i compose an email in TB i have to go back and correct. When i use Outlook 2019 (now possibly migrating to TB and / or Betterbird) i never have this issue as it always corrects the "i" to "I" when creating a sentence using UK language and dictionary pack settings. Why can't i do this with TB when composing.

Is there a setting for this. Many thanks in advance.

Running Windows 11 Home and Tbird 153.4.0esr. Tbird configured with IMAP. I have many years worth of emails stored in my Tbird profile folder. Profile folder is 25 GB.

I want to delete the bodies of all emails in the profile folder but retain the subject lines to minimize the size of the profile folder (while keeping bodies of all emails on the server). Then I can retrieve any email from the server.

Anyone do this successfully without losing emails? Is there a step-by-step procedure for doing this on the Mozilla website? (Google is giving me an Ai answer but not a link to a Mozilla answer.)

Good afternoon

I have been struggling to find some messages specific to specific dates and spend an awful amount of time tryomh yo access the correct one.

The solution proposed is a bit unclear to me, as it refers to "future folders". I need to unthread all my messages. Is this possible?

Thanks

PS The only version number i could find was for Firefox. There does not seem to be one for Thunderbird.

Thunderbird did not work last summer so I switched to Daily working similar and fine. One day forwarded messages started to contain a huge list of mail-data (Authentication-Results, DKIM-Signature,..) instead of just time, date, topic, adress. How can I get rid of this? Thank you

Hi, I’m having an issue with the appearance of the right-hand side where my conversations are displayed. It looks like it has reverted to an older version of the interface. Sometimes it switches back to the newer, more modern design, but in this case it has stayed on the old layout.

How can I change it back to the newer, modern interface? I’ve already tried changing the theme and restarting several times, but the issue is still there.

Could you please help me fix this?

Thank you!

Since our clocks/time went back one hour last weekend, Thunderbird for Mac is displaying the incorrect time. It displays the time as 1 hour ahead, effectively hasn't accepted the time change. The system time is correct, and Thunderbird is set to read system time. I have also tried changing it to "set manually" to our location, it makes no difference. Any assistance greatly appreciated.

I REALLY don't want to see prompts like this ... when FF upgrades to a newer release. I postponed clicking on adding this application since I really didn't know what it as going to do, or how to remove it once done. The little 'i' in the red circle did nothing. So - I finally clicked on it to make it go away. Not hat I call a very seamless upgrade.

Using Tbird many years, but suddenly my compose window changed to microscopic fixed font for all compositions. Cannot be changed (unless a trick known!) by any font controls I know. Rumor this happened at an update? Useless to send messages too small for anyone to read! What is fix?
