Mozilla has done it again. They seem to be on a mission to ruin their programs. I have already switched away from FireFox, and now I will have to switch away from Thunderbird if I can't downgrade.

I foolishly upgraded to 115.5.1. The new interface is more cluttered and takes up about 30% more space than the old interface. The bar at the top is wider, the bar between the email list and the email contents is wider. The side bar on the left which lists the folders is wider. And all this is happening even though I have "density" set to maximum. Furthermore, my favorite add-on is suddenly no longer working and I can't find a way to restart it.

What I need is this:

• Please tell me which version prior to 115.5.1 is the most stable and doesn't have any of the interface changes that 115.5.1 has. (How do I find out the number of the last version I was using?)

• Please give me detailed instructions on how to download such version and downgrade. I am NOT a computer person and I need clear instructions.

Thank you.

Hey there! After updating Firefox to 121.0.1 YouTube latest videos box not showing. It appears for a few seconds after page is loaded, but then just disappears. Checked on another computer -- the same issue, although in 120.0.1 works fine.

I am once again having issue with Hotmail and Firefox. It's working perfectly fine in Pale Moon, but it's gone totally blank in Firefox. It worked totally fine yesterday, but today I cannot access ANYTHING in Hotmail. Firefox says it's up to date, but usually when I start having issues with Hotmail, it's because Firefox needs to update. Please help fix this problem! All other websites work fine! Thank you!

only sometimes, when i get a new tab, from double click or anywhere else, appears a blue circle on the left side of the tab bar, it comes from the browser it gets bigger. ive just seen it from the corner of my eye. it just happens real quick

can someone help

I can open the Chase bank site, but cannot log into my account. I can log into my Chase account using Edge. This may have happened after the most recent update to Firefox. Any ideas how to fix this?

Ever since I installed Firefox 123.0, when I execute a search on Yahoo.com, Firefox automatically opens up a new window or tab (depending upon how you have it set up in settings) when it didn't before. When I try this with Firefox using Google.com to search, it does NOT open up a new window/tab. But when I try it with Yahoo.com when using Google Chrome, it does NOT open up a new tab. So it would appear that the behavior is being caused by something in Firefox.

I tried making various changes in settings and Firefox about:config that were recommended in previous questions here, but they did not alter the behavior. I would like the behavior to return to simply performing the search within the same window (I can always scroll back to get the original page). Can anyone help?

Hi!

This is an old question, but now over the time i can be more specific with this problem. What i know now in windows 10: - with firefox ESR sandboxie works fine all the time (now I use v 115.8.0); - with current firefox (v123) what happens is, after install current version, every time i open firefox, it works fine, but if i select "pause forcing programs", to change something in firefox, this means open firefox without sandboxie, now the first time i open firefox again sandboxie, it´s freeze, and can´t use for this moment now firefox sandboxie. Only works without sandboxie.

Thanks in advance.

Hello. I have put my language everywhere on the settings which is latvian. For possible translations i have only put english. Some pages, for example, whatsapp web is showing in russian ( i mean the app data for sure, not the messages), also some homepages i use open automatically in russian. How can i put latvian by default or if its not available for the homepage, put english automatically?

Hello, All

I need major help, please.

I am getting the attached messages when trying to send an email. Thunderbird worked perfectly yesterday morning, but then would not send any emails. I get emails, but cannot send from my 2 accounts.

I am on the latest version of Thunderbird, Supernova 115.10.1

Also, I cannot find out where to change my password for the accounts, because at times I need to fill in a password. I can't find it.

Thanks in advance for any help.

Best, Leslie

I would like to keep the size of my email folder from getting too big as the years go by. My plan is to have different folders for different groups of years. I created a new profile and deleted the emails from other years to just keep one group of years in the profile. Then I compacted folders, closed the profile, closed Thunderbird and looked at the size of the profiles in Windows 10. It showed very little difference in the size of the profile with a large number of emails deleted. I tried compacting each folder separately and still the size is not near proportional to the number of emails. Is it possible to compact the profile properly?

I turned my computer on; Mozilla wanted to update, so I said yes. Then I got this:

XUL Runner Error: Platform version '120.0.1' is not compatible with minVersion>=120.0 maxVersion<=120.0

And now I have no Mozilla. Restarting the computer didn't help. How do I get the old version back? I really absolutely must have all my bookmarks back....I use them for work!

Q: how to reactivate Or delete ?

I got an email this morning from my business partner saying that he was attaching a file that I needed. However, there was no attachment. I was about to email him back to tell him that he forgot to attach it when I realized that EVERY single email he has ever sent me in the past was missing its attachment. Even emails from months ago that I already read. I can see the paper clip icon, but when I click on the email itself, the paper clip disappears. If I try to forward an email, it looks like it's there as an attachment, but appears to be misformed or corrupted. Please help! My business partner is my graphic designer and has sent me hundreds and hundreds of emails with graphic design projects that I need access to. I have tested sending myself different attachments and they all go through. And am able to see attachments from clients as well - except for one that was not working. Any thoughts?

For some reason when I try to download a screenshot of [this tweet] it fails every time; I tested it and it's just that tweet specifically. This has never happened before and I assume it's just a bug since copy-pasting still works. Any help with this?

Good morning!

I share an outgoing server for my email, and have no difficulty sending from my personal (erin@grawlix.ca) only from my business (locksmith@grawlix.ca)

I noticed this issue on Wednesday, Jan 24th, though it's possible I didn't send a message through that account since Wednesday, Jan 10th.

I can send from both accounts if I go through my provider's webmail site (Shaw) with no difficulties.

How do I change the order of my email account folders in Thunderbird 115.6? I have multiple accounts and just added another, and I want to move it from the bottom of the sidebar to a higher location. I used to be able to click and move around accounts in the "account settings" mode. Now, that doesn't work. Is there a solution? The instructions provided in the video created by Thunderbird in 2022 doesn't work! Please help!

I just want to use Thunderbird to access a Newsgroup, so I deleted my gmail email account from Thunderbird (which Thunderbird apparently found on its own: it was in Thunderbird when I first started it).

But Thunderbird keeps trying to logon to the gmail account - popping up a dialog requiring me to provide my gmail password and authorize Thunderbird. It does this every 15 minutes (the frequency I want Thunderbird to check for Newsgroup posts).

How can I stop this?
