Firefox quite often will remove, replace, add, or layer text as I use it. It has been doing this since I first downloaded it, and I haven't had it for long. (I will say that it isn't the first program I've seen do this. the only other program I've seen do this is Zotero and Tor) I'm not doing anything weird with it, it just happens as I use it. Some of the screenshots I've submitted are of what I'm literally typing right now.

I've tried using troubleshoot mode, but it works just fine when I'm using troubleshoot mode, so I can't appropriately use that mode.

Good day, Is there a way to change the default zoom setting for PDF attachments on Thunderbird? (Without opening a new program/app?

I open up a PDF attachment from one of my emails and it default to Automatic zoom level. Due to my screen resolution this doesn't look good and I need to change it to "page width" each time. Is there a way I can tell Thunderbird to open in page width, or a set percentage each time?

Thank you for your time.

Recently when I load FF, something is injecting what looks like a Yubi Key character string and DUck Duck Go searches for it on the net. I have no idea what is causing this. It happens without the Yubi Key being inserted so is obviously a stored set of strings. I tried clearing the cache and history, but it still happens. Also, for some reason I have to clear the history and cache very often or FF will time out trying to go to a new web page.

Anyone have any ideas?

Since Wednesday I have been unable to send or receive mail with Thunderbird using the bellsouth account. I have had trouble with AT&T internet, but I believe that Yahoo has changed something on their mail servers. Can you help me to reconnect to my mail services?

I have installed Thunderbird in my new windows 11 laptop. The number in the "All Mail" folder keeps increasing, but it is empty! It says "No Message Found" It doesn't matter much, but the number will soon be in the thousands, and I don't know if it is using up the memory available to me. Ian McAllister

When I try to run firefox 141.0 (Linux x64) I get:

libxul.so: undefined symbol: gdk_wayland_device_get_wl_seat Couldn't load XPCOM.

Is there a way to fix this?

I'm using Slackware 14.2.

I'm running Windows 10 and recently switched from the ESR Channel version (128.11.1) to the Release Channel version (139.0.2) and, since then, have started having a problem where the unread email count displayed on the system tray icon and also the count on the Taskbar icon are no longer correct. Most incoming, unread emails aren't counted. This feature has always worked correctly for me previously, ever since I first installed Thunderbird several years ago. When I go into Thunderbird, the count of unread emails in whatever folder they're in is still correct, the problem is just with the counts on the taskbar and tray icons.

I'm not 100% sure, but I *think* it might be the case that emails which end up in the default "Inbox" folder are added to the counts, but those which are automatically allocated on arrival to other folders on the basis of filter rules aren't being added to the counts displayed on the icons. I have searched for others reporting the same issue and haven't been able to find anything, so it seems unlikely that it's a bug. I'd greatly appreciate any help in resolving this issue please.

Emails from certain senders (big companies like Amazon, Twitter and YouTube), after having been received normally for some time, suddenly stop arriving. They are not in a junk folder and nothing I have done has been able to get anything into a junk folder.

I also receive emails on my phone, and the problem messages ARE in a junk folder there. (I only just realised this.)

The problem seems to be that Thunderbird sees some messages as junk but instead of putting them in a junk folder it disappears them completely. From the evidence on my phone, nearly everything being flagged as junk is real email, things I want. If I could simply tell Thunderbird to receive everything it would be fine, but I don't know how to get these emails to download.

Looking at what is in my phone I see a load of important stuff that I really need, in my junk folder there. It's not anywhere in Thunderbird. How can I get this to download?

Using desktop 141.0, noticed issue of the hand pointer either not appearing, or appearing for less than a second and disappearing when hovering over buttons/urls/etc elements. Sometimes it stops being buggy for a minute or so and then goes back. I can't figure out the exact cause for this, but maybe going outside of the window of the browser ? Consistent in the safe mode, on different websites. See the gif for the visual

I have been using Thunderbird for some time now and i like it. BUT, the setting of a constant font size, fixed/variable width and Body Text/Paragraph is imo irrational, verging on stupid.

All of the above change at random while typing an email. Mindful this is a free email client for which i am thankful, what sadist developer(s) thought not having a simple procedure to set font, font size and format, like any other email client i have used, is not a sensible thing to do.

I am of the understanding that Thunderbird is influenced by the settings the receiver uses or the settings of the senders email. I don't care what settings they have or use. If they don't like the looks of my email, bad luck. All i want to do is type an email as efficiently as possible and send it. I sometimes spend more time changing back the format of the text i type than typing the content.

I have read solutions such as typing the email in notepad and then pasting it into Thunderbird. Really ! OMG

Looking for help on the www, the so called fixes are so old, the instructions are either not relevant or difficult to follow as the current Thunderbird has changed and things are different places and/or named differently. All this smack of Microsoft mentality where i am convinced things are changed for the sake of change or (cynically on my part) to mess with users.

Maybe Thunderbird can have 2 methods of setting up fonts, sizing etc etc. One a simple 'normal' way like other email clients, and the other as it currently is to accommodate what ever idealistic vision they have.

I use firefox on ipad instead of safari mostly to avoid questions if I accept cookies every time I enter a website. Must add that I use to make "apps" for every website I often wish to get in contact with.

My other wish for Firefox on IOS (ipad) is this:

Several program decided for windows like https://aseko.cloud/ -which is a small app, should I be very happy to reach on ipad. I can mention a lot others too.

Is there any options for Firefox IOS I can use to fix this problem?

The suggestions and autofill section in the Firefox Focus Android app is completely unreadable when app is in dark mode. Because of the poor contrast of using dark text on dark background. I had to switch to light mode to be able to view the suggestions.

Please fix it in the next update asap. Thank you.

It's puzzling when you ask "Why does my Gmail automatically sign out?" after setting it up in Thunderbird, especially since desktop email clients usually maintain a continuous connection. The message "You have been signed out of this account. This may have happened automatically because another user signed in from the same browser" strongly suggests a conflict, but it's typically a browser-related error, not a direct Thunderbird logout.

The most likely culprit for Thunderbird losing access to your Gmail is an authentication issue. Modern Gmail access in Thunderbird relies on OAuth2, a secure protocol. If the OAuth2 token becomes invalid or expires, or if Thunderbird's internal web component (used for the OAuth2 login pop-up) has issues like cookies being disabled, it can repeatedly prompt you for login.

Less common, but possible, are: Google's security systems detecting unusual activity and temporarily blocking access, or, if you're not using OAuth2 and have 2-Step Verification enabled, an expired or revoked App Password. While less direct, a concurrent, conflicting sign-in in a web browser using the same Google account could also contribute to Google invalidating sessions.

To resolve this, ensure your Thunderbird Gmail account is configured to use OAuth2 for both incoming (IMAP) and outgoing (SMTP) server settings. Also, verify that Thunderbird is allowed to accept cookies under its Privacy & Security settings, as this is crucial for the OAuth2 process. Removing saved passwords for the Gmail account in Thunderbird and then restarting it can force a fresh OAuth2 re-authentication.
