I understand, it's not an easy task, but the browser becomes unusable, if every time I install a new extension, there is no quality check whatsoever, and I end up having to restart in troubleshoot mode to find out which extension is causing parts of the webiste I am visiting to now show up. It's just frustrating. I very much value having to many extensions and that's why I use Firefox on a mac as the main browser, but something has to be done. Extensions should satisfy some basic rules and not cause malfunctioning!

I have a thunderbird account with access from three different computers. I have two issues with the account: after more or less a week the last thirtish emails trasfer automatically to trash, so I usually retransfer them to the inbox manually. BUT this week they have been permanently deleted. Not by me, the emails just disappeared... they are not in the trash. Nor in the spam folder, nor archive. I understand I cannot recover the last emails, but I would like to know why the emails are transferring to the trash automatically in the first place. I tried looking at the settings but I didn't find anything out of the ordinary. Please let me know, thanks!

Question above. Enabling sidebar (for vertical tabs) stops Wikipedia at any zoom from autodisplaying the Table of contents for an individual page.

I really wish I could stop this. Love vertical tabs. Love the Wikipedia Contents displayed by default. Can't have both.

Hi,

I have just started using Thunderbird and I'm trying to change the default colour for a hyperlink.

I have tried about:config -> browser.anchor_color and browser.active_color but neither has worked.

I also tried using a user.js file but that didn't work either.

I would have thought this would be a fairly basic thing but it seems to be impossible.

Is there a way to hide all folders from Unified Folders except for the Inboxes? I have both, Unified Folders and All Folders visible in the sidebar. For drafts, sent, junk, trash, templates, etc. I prefer to use the respective folders under each email account shown All Folders. But I very much like the Unified Inbox. What I would like to achieve (see the little mock-up image I made):

• A Unified Inbox (expandable to show individual inboxes, as it is now).
• Then directly under that, I want the All Folders section to show.

From reading up on the Unified Folders I understand that they are just Saved Searches. So I thought of creating a new custom Saved Search and include all the Inboxes. But unfortunately that seems only possible as subfolders of specific accounts. So I tried and created a Saved Search with all inboxes and IMAP search on under Local Folders. But I can't move it to the top of the list. And it also is not expandable to show individual inboxes as under Unified Folders. Any ideas if something like on the image below is possible to achieve?

I can only open my emails by right clicking it and opening in new window. Also keeps asking for password every time I go on Thunderbird. Have tried solutions on the help pages and online for both problems but not much use. Some things on account settings and security are not there to select. Is it correct that if I uninstall Thunderbird and then reinstall it the same problems will be present?

Recently did clean install of OS Sequoia and then all my apps, etc. Installed Firefox and noticed I had no horizontal or vertical scroll bars, (right side and bottom of browser page). I had do I get those turned on. I use a Wacom Cintiq 32 Pro and the pen so not using a mouse with a scroll wheel. Thanks.

in Firefox focus, DuckDuckGo is my default search engine. Whenever I do a search, I always have to turn safe search off unless I want to limit the results as if I need protection.

This is an annoyance. Is there anyway to change this default so that whenever I reopen Firefox focus “safe search” will ALREADY be off? I know I can change it during each session (a i think of it), but that is extremely annoying and I don’t always remember to do so.

Where can I find the settings for filters in Thunderbird for Android? I could import all my accounts with many folders from my desktop, but the filters do not work on my smartphone the way they work on my desktop.

I have a rule that moves email messages from backups to a 'Backup' folder. I also have another rule that moves emails address to myself to 'My Mail'.

When I start TB 128.11.1esr in the morning my 'Backup' and 'My Mail' folders show new email counts. When I click on 'My Mail' the number on it decreases and 'Backup' increases. This happens with other rules on other folders.

So, my question is this behavior caused my 'Message Filters' being triggered when I click a folder or potentially a latent refresh of the folders new email counts.

Thanks

Just installed the latest 139 version on two computers, the system tray icon for unread messages appears in Windows 10, but not in Windows 11, and it isn't just 'hidden' as I have many icons hidden and just a few visible and have already checked that. Is the icon no longer part of the program?

Hello community :)

hope everybody is doing well. I´m coming here with with asking for a help.

I´m managing browsers (Google Chrome, MS Edge and Firefox) in my company via GPOs. What we´ve been dealing with since 135 version came up is having the "Did Not Connect: Potential Security Issue error page , Error insufficient cert transparency" while visiting our internal resources.

Despite of having the security.pki.certificate_transparency.disable_for_spki_hashes set up -> main three certificate hashes are correctly added, basically copying the setup from Chromium browsers , where everything works as expected , Firefox is not.

The only way how to make it work is via security.pki.certificate_transparency.disable_for_hosts , which is , of course, not desirable , because of the security risks.

Does anyone face the same issues ?

Thank you very much ya´ll

The Firefox version I used before was Mac version 136.0 After I updated to the latest version, I found that the fonts of the browser's tab bar, search box, and bookmarks became significantly larger. How can I change the font size?

I previously successfully imported my configuration from Thunderbird desktop to my mobile app by scanning a QR code, and it worked perfectly. However, I recently had to reinstall my computer's operating system, which resulted in losing all my Thunderbird data. Now I'm trying to export the configuration from my mobile Thunderbird app back to the desktop version, but the export process generates a file with a .k9s extension. My question is: How can I import this .k9s file into my desktop Thunderbird installation? Any guidance on this would be greatly appreciated. Thank you!

We are trying to create an out-of-office response email and have found an issue. When creating the filter to respond with, the "Reply with template" option under "Perform these actions" is missing. We have checked the usual reasons why, but we cannot find what the problem is. We are using an Imap account. We have the 139.0.2 version of thunderbird, and we have set up the template necessary for the response without any issues. What could be the solution?

I can access addons.thunderbird.net with Firefox without any problems or being asked to "verify you are human by completing the action below.", yet when I try to access it from Thunderbird's add-ons manager, I am asked to complete the captcha, which after about 30 seconds of "Verifying you are human. This may take a few seconds." goes back to "verify you are human by completing the action below." I tried troubleshoot mode to no avail, I am not using a VPN or anything like that.
