Earlier this year I switched on Thunderbird to see what new emails had arrived. It started downloading ALL my emails from two of the five email accounts I have. I have a lot of emails as the accounts date from 2010.

Because I was concerned that I might exceed limits on the number of emails I can store on Thunderbird I spent hours going through the different folders and deleting as many of the duplicates as I could.

I switched on Thunderbird today and saw that the same process was happening again. In the time it took me to click on 'Work Offline' it had downloaded 263 emails I already have!

I would be very grateful if someone could tell me:

How can I stop it downloading the hundreds of other old emails? How can I stop this process ever happening again? Why is it happening at all?

Thank you for taking the time to read my request.

For obvious reasons I have unticked the 'Email me when someone answers the thread' so I may be a little slow in acknowledging any responses.

I wrote this on 13 June 2022: ...I am signed into a Firefox account. I have used this account on at least three different computers. I have downloaded the application anew at least a dozen times.

Firefox randomly, from where I sit, opens things in French rather than English. How can I keep it in English unless otherwise specified (I occasionally want German or Japanese)?

Thank you...

None of the suggestions worked. I reported that, but the thread was archived rather than answered.

How can I get all the info out of my account and try to start another that speaks English reliably?

Thank you.

Hello,

This recent update in how PDFs are handled is really poor. The responses to the effects of the update seem really arrogant.

No, your PDF viewer is not better than Adobe reader. Even if it was, I want the choice to download directly to my preferred app, even if you think it sucks. I thought Mozilla was all about choice? That's why I thought I donated monthly. I want control over the software I use. It's been a pattern with Mozilla, for example, removing about:config for people who don't want dev builds.

Just like desktop Firefox, I want to choose how to handle files and choose how my software works:

View in FF Download to disk Open in an App

No, i don't want to go the FF version first.

It's seems odd that I'm even explaining this. Please revert this change, it's bad for so many reasons. Please also consider why the culture at Mozilla is giving users less control, not more.

I have used Thunderbird for MANY years, so I'm not new to it. When using address book I want to be able to select multiple non-contiguous addresses and send email to those addresses only. No matter which of the hints I try in your new instructions, I cannot get this to work. I select one address, press the appropriate key to select the next one, but then first one de-selects. I have spent LITERALLY hours experimenting in an attempt to get this feature to work.

It doesn't work on my iMac or my MacBook Pro, both of which are using the latest Mac OS and the latest Thunderbird release.

Help!

When watching something on Youtube and I click on the coloured download icon, I get to be able to click on the title of the video. A blue 1 appears in the download icon. When I click again, then click on the blue 1 to watch the download. Nothing happens. The window just sits there and states 'downloading', but it does not happen. This happened last year and you managed to fix it; now Youtube seem to have blocked downloading again. Geoffrey D Dean, Australia.

So a few months ago I was having issues with Firefox so I deleted it. But today I redownloaded it, and it was working fine, but all of my data is gone my passwords bookmarks my history is there anyway to get this back.

Suddenly, neither my wife or I can send emails to anyone with a gmail.com address. I even tried sending one to my own gmail account and it failed. We're both using the most current version of Windows and version 102.11.2 of Thunderbird. Here is failure message.

I just noticed this issue about maybe 2 weeks ago. A few tests seem to show it only happens when I use the Google search engine as my default search option. I tried it with Bing search, and I had no issues. I also tried it in Chrome with NO issues either.

So, when I first open FF and enter a search word or phrase from the homepage/default page, it opens the default search engine Google with the results, along with the word or phrase I entered at the top in the text field under the Google logo. It's this text field that is the issue. I should be able to use the backspace to delete characters and change/update my search criteria, YET every time I press backspace, it just auto generates random suggestions, and then places the cursor at the end of the suggestions, thereby preventing me from being able to type my new search criteria!

I can press the X to clear the field, but then as soon as I start typing, it does the same thing, and starts generating random suggestions, and moving the cursor to the end of the suggestions each time, thus I'm still never able to enter my search criteria.

I have cleared cache, cleared data, uninstalled FF, and the issue still persists. I have noticed that sometimes after reinstalling FF, it will work properly for like a minute or so, but then the issue comes back. Also, doesn't seem to matter whether I sign-in using my FF account or not.

Please fix this as I do not want to use Bing for my search engine, and I really don't want to have to go back to Chrome either.

Clicking on a weblink in an email will open a new instance of Firefox, and bring me to my homepage. It should open a page in an existing instance, and open the intended webpage, not my homepage. I might have made a change in preferences that causes this behavior, but I'm not sure.

In the junk settings the “enable adaptive junk mail controls for this account” box is unchecked. But still some important emails continue being blocked and they do not appear in the trash folder. Is there another way I can prevent TB from regulating my email? I appreciate any help with this.

I've attached a screenshot of the error message I get about 10 times each day, even though I have no trouble sending or receiving emails!!! It's just a MAJOR inconvenience and a pain the neck.

Anyone in the same boat and has any one figured out how to correct this glitch?

Thanks

I have 3 email accounts that all receive emails just fine. Outgoing mail however only works with one of the accounts. The other two recieve this response from the server: Sending of the message failed. An error occurred while sending mail. The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again. I have tried every fix on the thread and researched the web to no avail. This just does not make sense as this problem just materialized out of thin air. What is going wrong?

Thanks for your help!

I've recently had to abandon my POP account and subsequently my ISP, who has stopped supporting email clients other than their own. I wanted to keep using Thunderbird and while I accept POP is gone, I wanted to maintain access to my old, downloaded emails as they form a useful database of information. I've done this by disabling the server connections of the old POP accounts but leaving accounts themselves in Thunderbird and adding my new web-based account (Protonmail) to download current emails into Thunderbird. All this has been accomplished successfully and works well.

It did take a wee bit of work to get all this 'successful and working well' and during the process Thunderbird has somehow managed to duplicate several folders that can not be deleted. They are all empty except for the ones with the > beside them and those contain the expected material that should be there (so are the ones I want to keep.) Any way of getting rid of all these duplications, especially in Local Folders? They don't seem to be hurting anything but I find them annoying.

I'm on a Mac desktop with Ventura 13.3.1
