I periodically backup my Thunderbird AppData information: C:/Users/<me>/AppData/Roaming/Thunderbird

I believe I installed Thunderbird from the MS Store.

On one device (MS Surface Go, Windows 11), this directory does not seem to exist. I have hidden folders visible, and several folders show up under AppData\Roaming, but not Thunderbird. I tried using %APPDATA%\Thunderbird, which works on my other devices, but the result is "not found".

I created a local folder ("save") and then used "properties" to display its location:

mailbox///C:/Users/<me>/AppData/Roaming/Thunderbird/Profiles/pv771buo.default-release/Mail/Local Folders/Save

When I put this into the file explorer and hit return I get told there is no app to open this 'mailbox' link, and I should look for one on the MS store. When I remove the mailbox/// it gives me the "not found" dialog.

I used the help->troubleshooting dialog to "Open Folder" under the Profile Folder entry, and got a "Location is not available" dialog. The dialog cited the same folder path as given above.

Where is the Thunderbird App Data stored? How do I access it????

Since updating Firefox I can no longer connect to known good sites without getting "Did Not Connect: Potential Security Issue".

This includes U.S. government sites! For instance, try connecting to https://covidtests.gov/ .

Why completely block access to the site? Why can't I make exceptions or tell Firefox to accept the risk and continue?

Good morning, I had asked a question early on Saturday, but was unavailable the rest of the weekend so just now responding to associate Corey Bryan's answer. I had gotten a message that I am using an unsupported version and they recommend downloading the latest stable version. He said it appears that I'm on the "Release" channel and most likely want to be on the ESR channel. I also mentioned that I am a cave-man when it comes to anything computer and am very skittish about making any changes as I don't how to straighten out any errors that might occur. He asked me where I installed Thunderbird from and the answer is that I don't know. It was an IT guy that did it many years ago. So I guess my questions are, if I've been using this version for years, do I need to or should I update it? If so, if I click on the latest stable version of Thunderbird, will that change anything on my computer, aside from getting the newer version of T-Bird? And will my e-mails in Thunderbird look any different? Thanks very much for the help. Tony

How do I turn this odd feature that dims FF bars when window loses focus? As of look of it only tabbar and toolbar are affected. I couldn't find anything relevant under "about:config". Also some tricks with CSS didn't work for me, maybe because I have custom chromeCSS that brings tabbar under bookmarksbar and applies other customization so that FF window looks like old good FF before they started to put everything on a single line in the bar. Thanks in advance.

The newest version of Firefox now has what seems to be a permanent sidebar on the left side of the screen. This is incredibly inconvenient as 1) I have no need for it or any of the AI stuff and 2) I'm using an older screen that is square and so now web pages are contorted when I view them.

Please remove this bar or let me know how to remove it myself.

Thank you.

What has happened to the "More actions" menu button - the one that normally is in the upper left corner of windows (see the attached image)?

I have just installed a new PC, with Debian 12 and KDE (plasma 5.27.5); the other windows have this menu button, but not Firefox and Thunderbird. Is there a way to get it back, eg by moving the menu bar out of the title bar and back to where it used to be?

You ask the Thunderbird users for volontary contribution at the costs you must give the possibility for payment with bank checks payment with bank cards and or PayPal is more and more difficult now for us. Under "please select" you must notice "Other" ! kind regards Antoine

Yesterday I had a problem controlling the Thunderbird layout. In a powerful demonstration of Murphy's Law, posting a detailed description here and waiting 24 hours seems to have made the problem go away.

I wish the same good fortune to anyone who reads this.

Hello,

           at one time I could login at home to view my Spectrum.net account on Firefox (default browser), now I get a popup which reads "This feature is currently unavailable. Please try again from home or contact us for assistance. IDID-4000" I get the same message on my laptop and desktop, both running Firefox. I can switch to the Edge browser and login with no issues. I have cleared cookies and used other suggestions I have read on the web, but to no avail. Any help would be appreciated!

Thanks! Tony

Having updated to latest browser version I am continually getting this page

https://www.mozilla.org/en-GB/firefox/133.0/whatsnew/?oldversion=132.0

It is not in my startup URL's I use the default.

I have cleared all browser cache and data with no effect.

Firefox on my 2018 MacBook Pro started having issues downloading all file types after I disconnected Dropbox sync and backup. Each time I try to download a file, a failed message is displayed below the file name and type. The browser was using the downloads folder that was synced with Dropbox. After disconnecting Dropbox, I tried changing the downloads location, but the "Choose" button does not display a window. The result is the same whether the Always ask you where to save files is checked or not.

I have gone through the following steps trying to resolve this issue with no success.

1. I have reset/cleared any configuration setting found using about:config and browser.download.
2. I have launched Firefox in troubleshoot mode and tested downloads with no resolution.
3. I have uninstalled Firefox and installed a fresh copy from mozilla.org with no resolution.
4. I have set the downloads folder in Safari, but this did not provide a resolution. Downloads work as expected in Brave and Safari. The current downloads location is the Downloads directory on my iCloud Drive.

The second screenshot with the error attached in still referencing the Dropbox-connected Downloads folder. No other browsers are using this folder and the Dropbox app has been completely removed from my laptop.

I use Firefox for web development and need to be able to download various files throughout the day, so this has become very frustrating.

Any help is greatly appreciated.

Cheers,

I do not see server settings option. Under account settings, I see outgoing server (SMTP) but not incoming! PLEASE HELP as my service provider changed their email client server settings and unless I can update, I cannot use Thunderbird.

im not very good with tech so ive probably clicked the wrong things, but i cant use my firefox at all anymore. only to search up 'google.com' lol. it opens on the homescreen, but when i want to search anything it always comes out on the screen in the image included. ive been using firefox for a year or so and never had issues. ive tried deleting and reinstalling, restarting my laptop, the whole deal. im on windows 10 but that shouldnt be the issue i imagine. ive asked some friends and they dont understand it either. id love to get some help otherwise i might have to go back to google chrome D:

Yesterday I attempted to set up an account on Hulu. Every time I put in a password, it was rejected. I tried multiple times thinking it was a problem with Hulu. Did not work. So I went to Chrome and was able to set up an account without password being rejected -- I wonder if there is a solution to this as I want to use FF -- thanks.

Hello there. I've followed the instructions in the appropriate support article and transferred our Thunderbird profile from a Widows 10 machine to a Windows 11. My profile as a .zip file is larger than the 2GB limit, so I used the Widows Explorer cut and paste. It's likely that I've done something slightly awry as one of my local sub folders hasn't transferred. Otherwise TB works fine. Is it possible to just restore the particular local folder, as I can find both the entries in my mail folder on windows explorer? However the view of the two entries looks rather different on the two computers when I compare a local folder that has transferred. Regards, Arthur

The list of previously visited sites in firefox windows seems to have shrunk in some recent update of firefox. Now, when I click the address bar I only get 5 options, the first being search with google and the remaining 4 being previously visited sites. Used to be that list was much longer. Is there a way to customize this, or revert it back to where it contains 10+ items?

Just noticed the book mark banner under the URL line. It is taking up screen space. How do I get rid of it? How did it get displayed? Did some searching but no positive results. Not sure what to search for, definitely not book mark. If I delete the items from the banner are they deleted from my list of book marks. Some of these\book marks I do not remember saving? Where did they come from, some AI search or paid for vendor adds?
