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

Recently moved to Linux Mint with Thunderbird 140.5. It's a new experience. Thunderbird has downloaded all my emails and folders from my Outlook.com account. Can send, receive, edit emails no problems and all is visible from Outlook client on other machines. Thunderbird does not show my calendar entries or contacts. I do not wish to import from Outlook as I would like to access my Outlook.com from several locations. Been through online Help articles. Nothing seems to work. Have installed TbSync and Lightning Calendar Tabs add-ons with default settings. I have tried suggestions provided in this Mozilla Support. Other forum suggestions don't seem to relate to the version I have.

I'm sure it is something simple as everything else I have done with my new environment is working wonderfully. Thanks in advance.

I’ve developed a Firefox extension similar to the RankingsFactor SEO Chrome Extension, which analyzes on-page SEO elements such as meta tags, headings, links, and canonical tags.

The core functionality works fine in Chrome, but when I ported it to Firefox using the WebExtensions API, I’m facing permission issues while trying to access or read the page content (DOM).

Here’s what I’m trying to do:

Inject a content script to read <meta> tags, headings, and links.

Display this extracted data inside my extension popup.

However, in Firefox, the script doesn’t seem to have proper access to the page DOM — even though I’ve included "permissions": ["activeTab", "tabs", "<all_urls>"] in manifest.json.

I’d like to know:

Are there any additional permissions required in Firefox to read page content?

Does Firefox handle activeTab or content_scripts differently than Chrome?

Is there a specific event or user action needed to grant temporary permissions?

Any help, code examples, or guidance on fixing these permission restrictions would be appreciated.

I am on a Windows 11 machine. Lastpass extension for the Firefox browser does not maintain my vault data. I have to refresh each time I go into the browser. This just started a couple of days ago. Perhaps after installing a new Tmobile gateway? Ideas on how to address/fix?

It's possible that I misread the documentation, but I looked for a response to this question for 20 minutes, and I couldn't find a 100% clear answer about my question when it comes to Firefox for Android.

Say I install an extension on Firefox for Android, that requires permission just for a specific website (e.g. let's say, for example, it's an add-on for blocking automated translations on youtube, with permission scope restricted to youtube only). Later, the extension automatically updates itself (as apparently, it's not possible to disable automated updates for extensions on Firefox for Android). The update now includes a larger permission scope, for example permissions for some other websites, or even the permission to "Access your data for all websites".

My questions are:

Is this scenario possible? If so, will I be notified of the changes in permission scope? Would I be able to block the update in this case?

Thank you.

Hello I want to use import-export tool and it is not possible now ? Please repair the function. thanks/CG

Moderator note (Denys): This question has been moved from the Firefox desktop forum to the Thunderbird forum.

i go to download an extension,everything is fine until i click the "download extension" button and then all of the sudden it takes me to this other page that tells me to download firefox but i already have it downloaded

Hallo, seit heute funktioniert die Passeky Eingabe durch die Bitwarden Erweiterung nicht mehr. Auto Ausfüllen von Passwörtern geht. Firefox und Bitwarden wurde komplett deinsatlliert und neu aufgesetzt. Ergebnis ist leider immer das selbe. Passworteingabe durch Firefox wurde deaktiviert. Vielen Dank

TOPIC 1 In Betterbird there is the option to colour the email account. The only option in TB is to change the colour of the email envelope icon. There used to be a extension that achieved this but fell by the wayside in TB 115 I researched this on TB forum on reddit.... https://www.reddit.com/r/Thunderbird/comments/17unvb1/different_account_colors_in_thunderbird_115/

It made interesting reading and I did download the 'account colours' zip to install and see if it worked. Only thing is that I do not know how to install it........can someone brighter than me tell me how to install it and to remove it if it doesn't work. Many thanks.

I downloaded a couple extensions to my Account, But how do I Activate them and use then and turn them on and where to go to see that there on and currently working? I'm using an Android Phone
