I have been through all the available help pages on how to change language from English(US) to English(GB). I've gone into the settings, added it as a language,moved it to the top of the list so it shows as the default language. I even tested by adding Spanish, then moved that to the top and sure enough everything turned to Spanish.

However, when set to English(GB), in ChatGPT text box, if I right click and go down to languages, I am only presented with English(US) (which is ticked as default). Interestingly now, doing the same now offers me English(US) and Spanish(ES) but NO English(GB).

Why, when I am clearly doing this correctly, is it not showing the option for English(GB)? Please advise as I don't want to go back to Chrome, but this is really irritating, especially in ChatGPT where it is constantly marking my spelling as incorrect.

Hello - I am unable to download any youtube file using downloading software on the Firefox brower extension.

I tried several apps on Firefox extension and it is the same result. Note, I have been using Norton antivirus software....but I didn't have this problem with Norton in the past. I recently re-installed Firefox. Please see screenshot.

I often use the Sync function to bring open tabs over from my smartphone to my desktop computer. I have noticed over the past month or so, this functionality has become increasingly unreliable and sometimes does not function at all. At the moment I have no synced tabs showing on my desktop. I have signed out and back in to Mozilla on both my smartphone and desktop multiple times, checked the sync settings, and nothing seems to resolve this. There have been a couple Firefox updates on both the desktop and mobile side, none of which have changed this behavior.

Has anyone else been experiencing this? What other trouble shooting steps can I perform? Any help is much appreciated.

Desktop FF version: v131.0 Mobile FF version (Android): v130.0.1

Hello, I've been using thunderbird since 2013, and have never had as many issues as I have this year. I reinstalled Thunderbird (uninstalled with revo uninstaller so nothing stayed), and then installed the latest version fresh. This seemed to smooth out most of my issues, but I haven't been able to solve this one..

I use Thunderbird because I have multiple email accounts to monitor and like them all in one place. The latest problem that I am having is that my "sent" email is showing up as giberish (sometimes.. Not every email, and not always on the same account).

My system is Windows 11 Home 64-bit

I will attach a screen shot of: 1. My current version of Tbird 2. The email that displays in Tbird 3. The email that displays in Gmail

Thank you in advance! -Eric

When opening an "ics" attachment I was given a popup modal, where I could change the default behaviour when clicking an "ics" attachment. I opted for open with thunderbird as a default, however I want to change this. When looking under "Settings" -> "Files & Attachments" only PDF and Text File are listed as content types with an according action. I also tried right clicking the attachment to see what options I would get but there are only the options "Open", "Save as...", "Detach..." and "Delete".

So there is no way for me to change the default behaviour of "ics" files that I could find.

Does anyone know how to change this?

I am using MacOS 15.0.1 & Thunderbird 128.3.3esr

Before the Thunderbird update to Version 128.3.1esr it was possible to click on an Event in the Lightning Calendar and drag it to a different day. You can still do this when the Calendar is displayed in 'Week' mode, but now you cannot drag an event to a different day when the Calendar is displayed in 'Multi-Week' or 'Month' mode.

Problem: newly added account disappears when TB is closed. Thunderbird on this PC (Dell Latitude 6540) has held a Verizon account for years. The "new" account is a different, equally old Verizon account kept on TB in an identical PC I no longer use. When added to TB on the present PC it tests and works fine until TB is closed. Repeated numerous times. Having read thread # 1286437 I did what follows , to no avail: 1. tried TB in troubleshoot mode; 2. tried in Windows safe mode; 3. cleared startup cache; 4. drastically pruned old emails; 5. looked up profile folder under troubleshooting info. Folder qxxxxxxd ( size 1.18 GB before adding new account) holds one folder tree, one directory tree, but NO prefs.js file. Instead, twenty-two prefs-xx.js files from 1 to 22; removed all to a thumb drive except prefs-1.js which I dared not rename as prefs.js; 6. found two profile folders, both labeled default. One is the above holding 1.18 GB, the other holds 685 MB (probably harmless and related to an old university account no longer extant). I copied both profile folders to a thumb drive. Note: profile folder qxxxxxxd is clearly engaged in what I am attempting. When TB is open with the added new account working -- which is the case as I am writing --, profile folder size increases from 1.18 to 1.20 GB and the number of folders increases by one (under "Mail" the list of pop.verizon-xx.net sub-folders increases from 17 to 18). Please advise on what to do next; I am 86 and no software geek, but can follow instructions... Thanks --Paul

Hello, When i get during the login process the "Authorize this sign-in Check your email for the authorization code sent to ⁨...." sign, it always result that afterward the account button shows "Account disconnected" sign, the browser not being able to sync my data.

I had that problem through every version of Firefox (Nightly, Beta, ...) on Debian, using the APT-Repo of Mozilla.

If i try to reconnect my account it results in a new request of "Authorize this sign-in Check your email for the authorization code sent to ⁨....".

Also this request feels like a joke to me, if i am asked for my TOTP-Code oder my YubiKey after the "Authorize this sign-in"-request.

Okay, so imagine this: - You want to go do something on a website, say Bacefook (as a demonstration). So you go search up "Bacefook", and enter. - You use the Google search engine, as it does the job. However, you notice it has been taking a few seconds longer than anticipated. - Your internet times out and returns an unknown host error. - You refresh, and suddenly the website perfectly loads.

Sometimes it even takes more than one refresh to get it to load normally! And this is not limited to the google search engine. It happens on all sorts of websites. There is near ZERO pattern to when it happens to not, and if I recall, it happens on other Wi-Fi networks as well, so this is a client-side issue.

And lastly, I use Firefox 131.0.3, the latest version of Firefox.

Clearing browser cache and/or flushing the DNS does nothing.
