In my Thunderbird I have some folders with names printed italic starting with "INBOX". The folders are empty, so it's easy to delete them. After deleting I don't see the folders anymore. But after shutting down Thunderbird and starting Thunderbird again, the folders are back... How do I delete the folders to not see them anymore?? (see also attached screen print)

Best regards, Marianne

Need an update for the update. My Mozilla settings say my operating system (Ubuntu 22.04) handles the updates, and it's a deadend. I can only use my browser for one minute before it freezes and a force quit is necessary.

When I try to use multiple desktops to arrange the opened windows, the window of Firefox is present in all of them, even the last one, which is usually totally empty (and when we drag a new window in it, a new empty desktop is created).

You can find attached screenshots of my three desktops, where Firefox appears (I blurred all info that could be sensitive, I hope I did not miss any !).

Is there a setting to unset this ?

NB: this is a duplicate of a post I made on askUbuntu, but it seems that this issue is more Firefox related than Ubuntu... And I did not manage to fix it with the answer provided there, so I'm trying my luck here !

NB2: oops, i just noticed that I inserted this question in the wrong topic (android), it seems that I cannot change that... I anyone see how to do it let me know !

I want to make a local back-up not only of my local Thunderbird folders, but also on the on-line folders. I am using IMAP and as far as I get, using the "export options", you only back-up data in the local folder. How do I ensure that I get a local copy of also the on-line inbox (and all of its sub folders)

Have to keep pressing keys periodically when streaming video in a Firefox tab to prevent the screen going dark. The Ubuntu Mate Power Management settings have all been configured to prevent the System from doing so, so I'm wondering if this has something to do with Firefox. As a caregiver for a disabled person otherwise without television access I would find this very helpful.

Hello. I am using Linux Mint 21.3 cinnamon and Firefox 144.0.2 When I use Google maps and the yellow small pointer (cartoon) to go on a specific street, the window come black when shifting to street view. My only extension is disabled, hardware acceleration unchecked, cache cleared and cookies cleared. I have made fresh install and nothing help. Troubleshooting mode allow street view to work fine but normal mode don't work. Google chrome work good. Chromium work good. And finally, Firefox work ok on my Linux mint LMDE 6.

Any idea where to go to solve this issue?

Thanks for your support

I am unable to sign in to my yahoo mail account. It gives me a fault that "something went wrong, please try another device". I can use brave as my browser and sign in with no problem but not with firefox. Any idea why?

Since I updated to Firefox 141.02 I have not been able to play videos on Paramount+ or Netflix. I get an error on the top that says the Widevine plugin has crashed on both streaming services. I have checked that the plugin is on and there are no updates. I am on Ubuntu 24.04. Video on YouTube plays as normal

if I type a hyperlink into the Calendar description field it does not link to the url.

The mouse pointer does not change from a cursor to a pointy hand when I hover over it

I have also tried using the 'Link' button and that creates a blue/underlined url like a traditional clickable link but the result is the same as before.

Please help troubleshoot the problem, at the moment I'm having to copy and paste every link which becomes tedious when there are lots of links

Thanks

Am having prblems authenticating oauth microsoft 365 from tbird ubuntu.. Everything was working fine but suddenly getting auth failures. Phone works fine, and all software is up to date.

Hi im trying to setup auto filtering for my IMAP account. The IMAP account already moves files to subfolders. But i still need to apply my custom auto filtering to them aswell.

This old post (https://www.thunderbird-mail.de/lexicon/entry/70-filter-erstellen-und-verwenden/) says it works with `mail.imap.filter_on_new` set to true. (It does not work for me!)

While this newer post (https://support.mozilla.org/en-US/kb/organize-your-messages-using-filters) says it doesnt.

Am i doing things wrong? Is it bugged? Is there no way to do it?

Thanks in advance! :D

I have a local file I wish to view in firefox without starting a HTTP server (it's only docs for a crate I'm building) however Firefox is unable to open the file despite the file existing and having correct permissions. The file was in a separate mount (disk) to where Ffox is installed so I copied to to /tmp/ to remove that as a variable but still no joy..

➜ ~ file /tmp/index.html /tmp/index.html: HTML document, Unicode text, UTF-8 text, with very long lines (3556) ➜ ~ ls -la /tmp/index.html -rwxr-xr-x 1 ben ben 4208 Dec 30 14:04 /tmp/index.html

Am I missing some new setting which allows local file browsing using the good old 'file:///' protocol?

Thanks, Ben

Hello! See the screenshot please: so, I downloaded à pay-bill, with Firefox (under ubuntu), in private navigation, and I get the file with a padlock-symbol at the end. What means that? What means that for me (on my computer), what means that for à friend, when I sent him the pdt-file (can he open it?). Nota: I understood that I can choose between "delete downloads when closing the privat window" or not. And I choosed not to delete them (but there appears this padlock-symbol). Thanks for your help!

Hi Mozilla I hav got a problem with Firefox on Kubuntu 24.04.3. Everytime the computer is restarted Firefox crashes the first time it's started. That's not a big problem, starting Firefox again don't take long. But the problems is exceeding. If i start Firefox by clicking a link in a mail in Thunderbird. And Firefox has not yet been started, It crashes, but now it's also invaliding the Task bar on the screen where Firefox was started. Invaliding means that I cannot start apps from that screens taskbar, and the clock has stalled, none of the tools works etc. The only possibility solution I have been able to figure out, is restart (It's like going back to Win 98). Sometimes I am able to start a app from that invalid taskbar. But it's not the one app that i clicked on. Even though I can trigger it via Thunderbird, the invaliding of the taskbar will occur after a while. And I have to restart. I am not sure if this is the right place to post. But Firefox is always involved, but maybe Thunderbird or Ubuntu was the right place? Every time Firefox crashes there is send a crash report to Mozilla, but is has been going on for a while, so i guess that nobody is looking at the crash report. If I use Chromium instead of Firefox I don't see the problem.

Untill latest update when on a site was link, ex. http://site.site/repository/text.txt i could select the link and from context menu select "open link in new tab/window" or "save link as". Now only "copy link" action is available. Im on Ubuntu 24.04.3 LTS Thanks for any response.

What settings do I need to get Street View to return the street view rather than a black screen in all 4 of my Ubuntu browsers, when it used to work fine but now is trash ?

I have recently encountered reproducible failures when attempting to download files or save pages to local storage. The target directory is located on a mounted NTFS file system with the options umask=007, user=root, and group=disk. My Firefox browser is running under a non-root user account that is a member of the disk group. However, I consistently receive the error message: “XXX could not be saved because the source file could not be read.”

I would greatly appreciate anyone's assistance in resolving this issue.
