HI, sorry my English is not so good -hope, you understand me. Since a few weeks I have a problem with firefox: after using the browser without any problem, I close my Laptop by dialing "Ruhezustand / hibernation". When I open my laptop again (regardless of duration), Firefox tabs are "grey", cannot be longer used. I have to close the browser completely and start again, very cumbersom! What can be the problem? IOS is updated, Firefox also. No other browsers have this problem. Hope you can help me? Best regards

Hello, recently I have found out that the theme I was using and loved has been deleted by the author, I have found its files and made a reupload here is the page link:

https://addons.mozilla.org/en-US/firefox/addon/world-machine-oneshot-restored/

I know that it is in Awaiting Review status, Steam Workshop has the same thing, but for some reason I cant install it into my browser, it keeps giving me (Download failed. Please check your connection.) error, but the tests during the upload are saying that everything is okay. Please help me, I cant live without this theme I want to use it!

(P.s: Sorry if its an question with an obvious answer, I am absolutely new to the FireFox)

Dear All,

I have the reoccuring problem, that certain Emails won't laod. They are in the Inbox, but when I click on them to see the content, Thunderbird only shows a black screen and is stuck in "Loading...". If I switch to troubleshoot mode, Emails load correctly - independent of whether addons are switched on or off in the troubleshoot mode.

I believe it mostly affects emails with attachments, but it is not limited to them.

I'm running Thunderbird Beta Version 146.0b3 (64-bit).

Does anyone know how to troubleshoot this, or has an idea where the problem might lie?

Best, Uli

I opened Firefox (V 145.0.2) on my Windows 11 laptop today and noticed that the starting window was the only one open, while I have had at least five windows open for quite some time. The "History|Recently closed windows" option is greyed out. I have closed and restarted Firefox dozens of times and my windows always came back until today. Is that window/tab history stored somewhere where I could recover it?

Thinking about backups of the browser state, I looked for my profile folder and discovered that it is empty - \Users\<username>\AppData\Roaming\mozilla is empty except for a file named vpn.moz. I then discovered that my profile seems instead to be stored under \Users\<username>\AppData\Local\Packages\Mozilla.Firefox_n80bbvh6b1yt2\LocalCache\Roaming\Mozilla\Firefox\Profiles with the folder name e5di8bjy.default-release I now learned that this location is standard for installation via the Microsoft store - the so-called MSIX version. But it is wrong that the "About"profiles" page shows that my profile is in the AppData\Roaming, not the Packages, location. When I try to open that profile folder, I get a message telling me that it is not available on this computer. It seems like the profile info should be aware of the actual location?

I installed firefox on ubuntu 24.04 following the guidelines from https://support.mozilla.org/en-US/kb/install-firefox-linux

I followed the direction from the section "Install Firefox .deb package for Debian-based distributions", adding the https://packages.mozilla.org/apt repository, prioritizing that over firefox snap from ubunto repors and finally installing firefox.

All good, now I have the latest firefox.

Question: what entry should I add to the "Unattended-Upgrade::Allowed-Origins" section of "/etc/apt/apt.conf.d/50unattended-upgrades" in order to enable unattended upgrades for the mozilla repo?

Googling this got me different contradictory recommendations that did not get my system to firefox 146 until I manually run the apt update/upgrade.

Thanks!

First noticed when listening to music on YouTube while playing a game: After a few songs, video would stop, shortly followed by audio (Every few minutes it might play less than a second of audio). Somewhere along the line any interaction with YT itself or even the tab stop working. All other tabs work fine.

Firefox doesn't ever crash, and I can't see anything weird when using a process viewer (I'm not too familiar with Linux diagnostic tools).

So far I've tried:

• Updating Firefox
• Disabling Extensions
• Clearing cache
• Uninstall Firefox
• Multiple Proton games through Steam
• Game running through Wine
• Updated OS

I've tested with Chrome, which had no issues.

I don't recall messing with anything at the time (I did change some settings in firefox, but I think that was a few days before the issue started).

Bei jedem Öffnen von Thunderbird bekomme ich mindestens 200 mal diese Fehlermeldung angezeigt. ich habe mit Mail Merge gearbeitet, jetzt jedoch deinstalliert: Dennoch permanent die Fehlermeldung. Wie kann ich den Fehler beheben? Siehe Screenshot

Hello everyone,

like the title says, I want to set appointments in the calendar to private. I have shared calendars. Therefore, I need to be able to set some invitations to private.

In Outlook, it's no problem to set an accepted appointment to private, but in Thunderbird, this option only seems to be available for appointments I have created myself.

In account setup There is an error: "Incoming Server already exist"

Damn bloody right it already exists. Or do I need to specify servers that don't exist. Just make one up or so ?

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

I'm using the latest version (145) and I've setup my office 365 email account. I'm trying to setup my calendar account as well but when I enter location, username and password it says that my credentials were not accepted.

I assume this means that TB is using legacy un/pw authentication which is no longer supported instead of OATH2. There is, however, no option to select OATH2 in the calendar setup process (like there is for email).

Are office 365 calendars supported by TB 145?

Hello Everyone,

In Thunderbird, I'm receiving a notification that I had a new email, but then it disappeared and didn't appear in my inbox. It reappears after about an hour. (but i'm not sure if i'm receiving all the email email or not) This happened after updating to Windows 11.

There is enough space. I uninstalled and reinstalled. It's up to date. The emails are not in any other folders. The same problem occurs on the website. Everything is working OK with my company email address; the problem only occurs with my personal email address, and I use both on the same laptop. This issue happens with all received emails from all email providers, such as Gmail and Hotmail..etc. Can anyone help me with this issue?
