I have a Thunderbird on my laptop with a big folder in the Local Folder. It has a labeled "mail window" having 5,044 messages in a folder named under the internals of the Profile as "Family" and "Family.msf". Under "Family" are at the next level called "Archive-A" and "Archive-A.msf". (This may not be a kosher "archive".) I tried to use NanaZip to prepare as a zip by Exporting it the other laptop's Thunderbird in our house, but the process seemed to hang before that could do it. Maybe there had to be two levels, I dunno. Maybe getting from a .ZIP to a .SBD....

Even if that had resulted in a useful .ZIP, I'm not at all clear how I could I succeed in importing it into the main profile on the other TB computer. I am defeated at this point.

I wish I had a "Thunderbird for Dummies", or at least a manual + a lexicon with acronyms.

Could someone help me out?

Thanks!

I recently suffered from the "127.0.1" not compatible error. Eventually I was persuaded to reinstall firefox from the Mozilla oficial site using Edge, despite having reservations about losing my passwords etc. which has happened before. Fortunately, the installation routine included an update option which preserved all of that. However, my menus bar (File ...... History, Bookmarks...) is missing and I cannot find any way to get it back. I rely upon it to restore previous sessions, because I routinely have the same 7 tabs open and want to be able to get them back after an update or laptop shutdown, and also use it to search history and find bookmarks that are not in the bookmarks bar. Any help welcome.

As an asside, my pet hate is updates to any application that remove, move, or hide a very useful feature without explanation or warning and claim to be to "improve the user experience". Take it from a long standing user, they don't. Quite the contrary.

I am considering moving to Thunderbird from MS Outlook. I want the rules I have already setup in Outlook to work in Thunderbird. Is this possible & if so how do I make it work.

Would you please help me permanently remove cache2 folder from Local Folders please. I'm using Thunderbird 115.12.2 (64bit) on esr channel with Windows 7 Ultimate Service Pack 1 OS.

I don't want Local Folders / Cache2 folder (or incidently Inbox, Drafts, Archives, Junk, Deleted and Outbox) but Thunderbird highlight - right click - delete button doesn't get rid of it. I can temporarily delete the Doomed and Entries sub-folders with right click - delete - delete folder but they move to Deleted folder where once again they can be deleted the same way but when restarting Thunderbird they are back under the cache2 folder again.

Even after exiting Thunderbird and directly deleting the cache2 folder(s) in system AppsData - Local and Roaming Thunderbird profiles the cache2 folder (with persistent sub-folders) returns to my Local Folders when restarted.

If ignored I eventually end up having a cache2-1 folder etc.

Like all of us, I get bombarded with spam emails. So I set up filters to separate the "definitely spam" from "possibly spam". I've been doing this for many years now. But recently, maybe for the past few months, I'm finding that these blacklist filters aren't working anymore. The filtering failure seems to be getting worse as time goes on. And, yes, I do a match on "any", but that still doesn't work. As I said above, my filtering rules used to work just fine, but possibly a new Thunderbird update several months ago broke filtering?

Also, is there a way for filtering on the message content URL? I find that sometimes that's the only way to distinguish spam.

I have in my laptop a external webcam a Logitech Webcam C930e. The webcam is a HD webcam with 1080p. But in Google Meet in Firefox I can only configure it at 720p but in Chrome I can configure it at 1080p. Why have that behavior?

I added my own shortcuts and deleted all the preset ones (Wikipedia, Twitter, Amazon etc). On deleting the last one of the default ones, the 'Add a shortcut' button has completely disappeared. Is there another way to create a shortcut?

why is there no back button on thunderbird? I clicked on a message (have to click twice on it now in the lousy upgrade I was forced to use), and now I can't go back to the inbox. What's up????

This is a follow-on to https://support.mozilla.org/en-US/questions/1401783, I have the same problem - I've followed https://support.mozilla.org/en-US/kb/extended-add-support (which is for some bizarre reason marked "no longer maintained"), to create the custom collection https://addons.mozilla.org/en-US/firefox/collections/17515772/raxod502/ so that I can override the arbitrary blocking of third-party extensions that Mozilla applies by default.

This allows me to install most extensions but for some reason https://addons.mozilla.org/en-US/firefox/addon/duochrome/ is not showing up in the interface on Firefox for Android, despite being in the custom collection. No information is given about why it is not showing up. I am not aware of any reason why it would be blocked. Here's the manifest.json: https://github.com/FreshSupaSulley/Duochrome/blob/main/firefox/manifest.json

How can I fix this and use whatever extensions I want to use, or at least get a valid error message about why Mozilla is blocking the extension?

Creating a new thread since the older one just says "Even using that approach, not all add-ons are supported in Firefox for Android at the present time", which doesn't help at all - there is no reason why any addon should be blocked for mobile usage unless it is explicitly configured as such, and even if that were reasonable, it doesn't help explain what specifically is wrong with the extension I'm trying to install.

I would like to know what the options below, contained in the settings editor, are for and how I can adjust them so that every message sent is configured to require confirmation of receipt by default:

mail.identity.default.request_receipt_header_type mail.identity.default.request_return_receipt_on mail.incorporate.return_receipt mail.receipt.request_header_type mail.receipt.request_return_receipt_on mail.request.return_receipt mail.server.default.incorporate_return_receipt

Is there a way to set a separate theme for the private browsing option? I like being able to visually distinguish between the normal browser and the private one, but enabling a theme seems to set the same visuals for both.

If separate themes are not a thing, perhaps they could be added in a later update?

Thanks for all your time and effort.

Hello, I use Duck Duck Go as a default search engine, with Google and others as alternatives. Since I switched my compter, Firefox resets the default engine back to ebay, which cannot be deleted in the list and also shows up in the address bar. Could you please tell me how to get rid of it? Thank you very much!

I have a fresh install of Debian 12.5, which came with Firefox 115.7.0esr. Firefox is inconsistent in following the settings I put in. For example, I specified the download folder, but it still automatically saved to the original default folder. But when I clicked to ask me before downloading, it does! And it gives me the 1st option to save the the folder I specified. But if I uncheck the "ask me" button, it goes back to putting downloads in my home directory, which I don't want. Another example is I've set it to "open previous windows and tabs on startup", but it doesn't. When I close Firefox with several tabs open, the next time I start it I have just the home tab. Yet when I look in "settings" it still says it's supposed to be opening my previous tabs. This is more annoying than the download issue. How can I get Firefox to follow the settings, which ARE being saved?

Hi, I am experiencing an issue with desaturated icons in the toolbar and tabs of Firefox. I don't think any extesion may be causing this problem and i have already tried reinstalling and resetting Firefox, but this did not resolve the problem.

why everytime i use firefox the default web address is: https://hao.360.com/?src=lm&ls=n077c1cd59a

For many years I have used the ability to set shortcuts to website on the Firefox home tab, using the method given at: https://support.mozilla.org/en-US/kb/customize-items-on-firefox-new-tab-page#w_pin-unpin-or-remove-a-shortcut.

However, today, when I try to edit a shortcut link, I do not get the 3 dots menu by right clicking on a shortcut tile.

Is this a recent change, a bug, an issue with my installation (which has been stable for many years)?

How can I get back the functionality back?

I am using Firefox 127.0 (64 bit) on Windows (Windows 11, all up to date).

I have stayed on an old version of TB because of the old extensions that made it a much better product.

With the installation of Win 11 I decided to try the latest version of TB. I have to say I am not impressed. I forgot how much better TB was with the extensions.

My first question is how do I get to sort the order of items I see in TB? I want News & Feeds to be displayed above my email accounts. It would seem that this would be easy but I cannot find a way of doing it. What am I not understanding? Surely this should be simple? I want to choose the order of everything.

I also customised the interface with better scrollbars etc. None of the add-ons I used to use seem to work with the latest TB. At the moment the new install of TB is incredibily ugly. How do I change that?
