Your latest request for donations has evidently come with a forced upgrade which I did not authorise. I have been happily using an older version of TB because it supports my add-ons and themes. Now because of your uninvited intrusion they no longer work. Furthermore it seems that I can no longer download an older version that supports my requirements. NOT HAPPY!

Thunderbird update ruins my folder setup with sub folders under Inbox

There must have been an update for Thunderbird that screwed up the way I have been using Thunderbird for years now. I had sub folders under inbox. For example, I had an investment newsletter go into a sub folder under inbox labelled "inv". I had a filter set up to move emails that had the name of the newsletter in the title to go to that "inv" folder. In this new version of Thunderbird, those separate sub folders are gone. The filters are still there but the folders are gone. Now all emails just go into the inbox. Is there a way to roll back to a previous version?

TIA Eric

Where I can find a step by step process to move from ESR 128.5.2ESR to the new version of Thunderbird (not the esr version)? Been crashing, caused by Bitdefender.

I didn't know there was a non-ESR version of Thunderbird until I found out by chance a few days ago! Since the latest update to ESR 128.5.2 has crashed 11 times this week, I would like to move to the latest version (64 bit?) non-ESR. There must surely be an official Mozilla step-by-step guide to doing this?

Ever since Version 146 was automatically downloaded, all I see is a blank page and several icons across the top representing individual mail. (See pic attached. Before 146, I saw all my mail listed.) The program freezes; I can't click on any icons. Most of the time I am just waiting for something to load. I have to fight to get my folders to even see my mail. How do I get Version 145 back?

Can I permanently turn off InformationUpdate available' which appears each time I open Firefox. I must click Dismiss to close it. The problem is that after each update, many services to which I log every day, state that I am logging from a new device and I must complete a time consuming procedure of adding a new device in many places. And I don’t need most of the updates.

I was having massive issues with TB when it auto updated from 142 to 143. Then last week, just when I thought I had everything restored, the damn program auto updated to 144.

I still can not "delete" messages or send anything.

I downgraded to 140.3.1 at least with that version I could delete messages. But I still could not send anything. TB send would time out and a window would pop up asking me to "sign in with my ISP".

And like others that have posted, I too lost folders on the new updates.

This whole series, 14x is a bust IMO.

Since updating to 141.0 64 bit today (Jul 22, 2025) my addon Filtaquilla is disabled.

I tried another attachment saver and the same thing happened. Okay, I'll revert back to previous version.

Can't do that without starting a new profile.

Sure glad I donated to Thunderbird last night.

I am currently running Thunderbird 137.0.2 (64-bit) and I don't get an automatic prompt for updates and haven't been getting them since I updated to Supernova and now Nebula.

I have the settings set to Check for updates, but let me choose whether to install them, which is the setting I have always had and I used to get automatic prompts for updates with a window opening to show the details of the update as I get in Firefox.

Can someone tell me how to get these automatic updates back.

I have attached a screenshot of the update window.

Thanks.
