Hi : We are planning out server farm capacity, network gear needed, for a new site for our AI micro-services. We are curious when do you think that Firefox will support TLS 1.4 ? and will the overhead/utilization difference be between TLS 1.4 and 1.3 which we currently use exclusively. I understand that we are talking servers, and FireFox is a browser, but we cant dig up any real-world stats on the workload difference between the two. Any help would be appreciated.

Thank you for your time Albert Baker.

Now it's completely impossible to open PDFs outside Firefox, as I could do until the last couple of beta versions.

This trend is going on since a few years ago, from bad to worst. The whole design of the PDFs download process is bad. PDFs should be treated by FF as any other file: download and open with the system default PDF viewer. Imposing Firefox's internal PDF viewer as mandatory for downloaded PDFs is nonsense.

I am about to lose access to Outlook. My current settings show imap.mail.yahoo.com and smtp.mail.yahoo.com and it is working. This is an sbcglobal.net account. When I look at what ATT says it should be due to changes they made it reflects imap.mail.att.net and smtp.mail.att.net. The ports are the same between both choices. It says on both of these when entered that it can't access and the user name or password is incorrect which is not the case. Any help out there???

Hi Firstly, thanks so much to everyone for this much anticipated Thunderbird for Android. I've been using Thunderbird for years and am very excited! But I don't (as yet) know what I'm doing! I have set up T f A via QR codes and now have a list of all my accounts on my phone, They are in little circles on the left of my phone and then on the rest of screen it says Unifed inbox and then Outbox (which is highlighted in blue). (Image attached) Currently in my unified inbox there are 39 emails. So 2 questions: how do I get all the (many) other emails I have in my desktop app to come into my mobile app? And how do I only see one inbox instead of the unified inbox? - when I click on the name of an inbox at the top of the screen it just moves on to the name of the next inbox. Thanks Lynne

Thunderbird, quite suddenly, stopped getting my email; Both on my account and my wife's account at the same ISP. I spent more than two hours on the phone with the ISPs help line trying to resolve this issue. They also use Thunderbird at their help desk, and the agent I talked to was familiar with your program. She (the agent) was not able to replicate the issue on their system. We then tried to set up a NEW email account. I carefully entered all the info needed for a new account, following instructions from the agent, then hit the 'Test' button. I got the following message onscreen: "THUNDERBIRD FAILED TO FIND SETTINGS FOR YOUR EMAIL ACCOUNT" The answer to the original issue suddenly became very clear - Thunderbird cannot, or refuses to, connect with the email server, therefore NO EMAIL. We tried everything in her toolkit to resolve the problem to no avail. We finally tried UNINSTALLING Thunderbird (and the Maintaince program). Once Uninstalled, I used the Registry Tool on CCleaner to remove any entries in the registry referring to Thunderbird (there were several), then restarted my computer. I then downloaded and installed a totally NEW Thunderbird program. When I ran the Thunderbird again, I found all my account(s) info was still present, and Thunderbird was still unable to find the server. I'm at my wits end trying to resolve this issue, and REALLY HATE to go back to Microsoft OUTLOOK to get my email. Anybody got any ideas??? Any help would be greatly appreciated. (Signed) Proteus

Thunderbird freezes on loading. It seems to be working (window notifications show incoming mails). The top bar has one item which says "loading" but never does! I am running WIN 11 pro with AVG. I have tried the following: - open TH in program safe mode - Open TH with laptop in safe mode - uninstall and reinstall - Open with antivirus turned off - Deleted all .msf files in current profile (judging by time and date) which seems to have been called xxxxxxxxx.repair . On restart TH did not reinstate the .msf files and the blank frozen screen was still there. - there were about 4 other profiles in the directory although in reality there should only be one. These profiles have various names: defaultnew, default (2 off), default-release and repair. - All profiles except the one with ".repair" were copied to another location before restarting. Any help would be appreciated.
