Can I downgrade from a beta version to a regular version of Mozilla Thunderbird?

Like this TB community, I'm asking if anyone knows or has experienced something like this. I'm assuming you first downloaded a beta version of Mozilla Thunderbird, and it worked and was configured, and you want to downgrade to a regular version of Mozilla Thunderbird without losing your messages and settings. What steps do you recommend to achieve this? Or is it not possible? Thank you and have a nice day.

Gracias y que tengan lindo dia.

Hi,

I have a very old version of Firefox (51.0.1 64-bit) on Windows 7 Pro. I know it's well out-of-date. It's not my "main" browser, but there are some things I use it for because there are (were) some handy old extension on it. For example there's an extension that simply copies any text I highlight, without my having to press CTRL-C. I find the "scrapbook" invaluable for saving info offline.

Yesterday everything was fine. Today ALL the extensions have been disable because "[extension] could not be verified for use in firefox and has been disabled". There is no option to enable them again.

I have backups of the extensions (xpi files), but firefox is telling me that they appear to be corrupted.

Is there any way to either enable the disabled extensions, or force firefox to reinstall then from my backups? I have toggled "xpinstall.signatures.required" to "false".

Thanks for any help.

Windows 11 23H2 FireFox 136.0.1

When clicking check for updates it firstly shows the rotating arrows icon for a long time and then says "Failed to Check for Updates"

I've completely reinstalled Firefox and this continues to happen

I do not have NordVPN or any other VPN installed

The behaviour is the same in troubleshoot mode

very frustrated, and pissed at how programmers always screw things up that are working just fine by upgrading crap. Now, I have suddenly had all of my addons quit working, was forced to update my firefox. Nothing changed, and it still shows that I am using version 105, instead of the all-new, better and fancier, singing and dancing crap that is being forced upon me.

Hello, I want to update the browser version on my "Huawei matepad t8" device. There are no Google services on it, only the app gallery. You cannot download the installer for android on your official website. It redirects to the Google play store. How do I get updates? Can I get a direct link to download the .apk?

i was browsing youtube and suddenly got an ad, which is how i noticed my add-ons were gone. all of them, not just the ad blocker. and they had still been there like a couple of minutes ago. when i go to download any extension, i've tried a lot of them, it just says "installation aborted because the add-on appears to be corrupt" but it doesn't say what i can do about that. please help!

Running TB 136 on my new Macbook, I transfer my old profile from TB running 128, I use IMAP. The first thing that I noted was emails in my Drafts, Sent, and Spam folders did not transfer, and the Template Folder is missing. I did the transfer by moving a copy of my TB profile to the new install. How do I get the missing emails and the Template folder?

Thanks! Charles

Just found out my copy of foxy proxy standard, wappalyzer and one other, cookie manager were no longer working because this message, Installation aborted because the add-on appears to be corrupt. Updated to a newer version of Firefox in Kali Linux but have the same, message,Installation aborted because the add-on appears to be corrupt. Was just working a few days ago . I even did an update in Kali to see if that would solve the problem .Same message. Used CURL to update to current version of Firefox , supposedly, same, Installation aborted because the add-on appears to be corrupt. Do think I need to renew any certificates here because in WIndows 11 it updated automatically without problems. What do you think.THX

Hi there, I updated Linux Mint today and now have a crash effecting access to Netflix. First time ever to occur. What is wrong and how do I fix it?

Cheers, Ivan

I normally use Firefox Developer Edition, version 127 because any later version always freezes my whole computer (probably because I'm using a 15-year old PC). Recently all my extensions became disabled. I'm now also unable to install any extension because it says "Installation aborted because the add-on appears to be corrupt". I found some instructions on Mozilla website about deleting compatibility.ini and extensions folder, but it didn't solve the issue. Now I'm stuck and confused as I suspect some of the extension files that should be in my Profile folder may not be there.

The simplest solution in this case would be to use the "Refresh Firefox" option which resets everything to default settings, but every time I do it my computer freezes until rebooted. Uninstalling and reinstalling manually is also not the way to go, because it retains all the settings.

I've tried installing the standard Firefox browser (v. 119) alongside the Developer Edition but the same issue is there as well.

I'm looking for an alternative way to get a clean Firefox install, so I can fix my extensions.

Additional info: - Your system specs? Windows 10 64-bit, 4 GB RAM, Pentium Dual-core, no GPU - Hardware acceleration? Disabled. - Using any mods? Yes, two. Geckium for Firefox, which always works fine. The recent issue started when I played around with Revert8Plus, but it initially worked without issues.

I recently moved my TB to a new PC desktop, and TB is working fine. But I see that my local archive folder is gone from both the new and the old PC, as well as my NSTMP folder. Could someone help me locate them?

thanks

Bonjour Suite à l'installation de la dernière mise à jour j’ai perdu mon organisation et des favoris de Mozilla. J'ai arrêté mon pc dimanche dernier dernier et quand je l'ai rallumé vendredi et lancé Mozilla j'avais tout perdu. Comment récupérer mes données tout en sachant que je n'ai pas de sauvegarde. Espère que je vais pouvoir récupérer les infos car à priori les données dans le navigateur datent de plus d'un an Merci bien de votre aide

So, what working on CIA and being irresponsible in imposing update on user client tells us about corporations, concolidated on the west cost of US? I think it is threat to the national security and sovereignity of other countries and irrisponsible behavior and would provide support for restrictions of such corporational policy. Why such policy as firefox does should be allowed? Why design of internet architecture in favor of international company should be allowed on the level of national state by national state? And why with such policy design, working on restrictions and separation of your national states neworks from global architecture considered immoral?

Your excuses, nerds?

Hi team,

I tried switching over to the monthly release branch however none of my addons work.

Is there some major incompatibility introduced (aka WebExtensions)? I can not find any documentation anywhere as to what changed or why an extension would not work with 129+.

Also the release notes do not mention that 136 changes the Profile format, requiring a redownload of all messages from the server and therefore reindexing. This took several hours, only to find the addons don't work. Downgrading Thunderbird gives a profile error, and requires the `--allow-downgrade`switch to restore functionality. There should be a warning in the release notes regarding the one-way nature of the upgrade.

Thanks!
