I can't send emails out of Thunderbird but can receive them, not sure what to do? Is there a phone number I can call with Thunderbird for help? I'm not that savvy with all this.

I have my University of FLorida (UF) email downloaded in thunderbird. It is IMAP so whenever i delete something on the UF website it then deletes in Thunderbird and vice-versa. I am now experiencing for the first time in years a few emails missing in Thunderbird, but that are in the UF website. See for example the email below from PC-Progress I received yesterday (5/16th) at 10:28 am. It shows on the website under imbox, but not in Thunderbird. When in Thunderbird I put the PC-progress email in the search box it founds the email (see screenshot below), but when I click on it it goes to the conversation and the email is not there. Any suggestion?

When I try to search or use Firefox it is extremely slow and I get an error. I used microsoft edge and do not have this issue. I am ready to stop using Firefox and got back to Microsoft Edge.

Firefox crashes randomly with no crash report being generated. It seems to have started doing this about a month ago. Nothing in particular seems to trigger it, and all of my software is up to date. It just closes any and all tabs that are open, as if I exited out of the program entirely.

Hi all, I have two Gmail accounts, one private and one organizational, each one with its own unique problem. I access both accounts through Thunderbird for Windows, the Gmail Android app, and Chrome on my laptop. I use POP to be able to access the emails even when offline and store them in subfolders. I have learned that if I keep the messages marked as unread on the phone and Chrome, TB will download the messages.

1) My private Gmail account downloads only 4-5 messages at a time, and I have to manually hit: "get messages" many times until it downloads all the messages. Very annoying.

2) My organizational Gmail account through the university worked fine and downloaded as many new messages as were on the server. Until May 9th, when it stopped connecting with the Gmail server. It keeps asking me to re-enter the username and password (which it had saved, and hadn't changed), only to claim that Gmail is not accepting cookies. Needless to say that I haven't changed any of my cookies preferences neither on TB (which accepts all cookies) nor on Chrome (which blocked 3rd party cookies, but had an exception for the University's servers). I tried enabling any type of cookie in the account on Chrome, but that didn't help. I tried changing the authentication from password to OAuth2, and it didn't help.

I would appreciate your help. Shahar

I have a user who is using an imac late 2012. When the user installs firefox release version 100. Firefox will open but will not go to any websites. All other web browsers work just fine but for some reason Firefox will not sync and will not open websites.

Hi, I'm using Thunderbird chat with XMPP and Openfire as XMPP server. My only problem is that I can't transfer file on chat window. However, I can easily send files on other XMPP client such as Pidgin or AstraChat.

So, my question is, does Thunderbird chat support file transfer ?

Thx

Ever since last update, Thunderbird has not worked. Runs out of time, to download new messages, won't let me delete messages. Thinks for a long time. Uninstalled program and then reinstalled . No change. Not sure what is going on.

I'm having a problem related to an extension that I have to use to consult legal processes in my country (there is no other way, the extension is widely used and is a requirement, I've always used it). Not too long ago this browser started having problems with the extension that hurt my company like hell, this is our last attempt to continue using this browser.

I've been using Thunderbird for almost 2-3 years and lately, I was connected to a limited internet connection and noticed that Thunderbird is consuming more than 25GB per day on average. Although my emails are not changing that frequent but it keeps on consuming a lot of traffic.

I'm using configuration for Exchange mail server and synching the mail every 1 minute. The size of the offline messages is 3.5 GB

How can I stop this consumption? Or at least to understand why is this happening?

while I was running a game on steam (Apex legends), and Firefox on my other screen, I was using too much memory, so the steam game and Firefox crashed. The game works fine, but Firefox won't load anything, Except for settings and the "About:" pages. When I try to visit a website it does not even attempt to load it, but the website does show up in my history. I've restarted Firefox, I have reinstalled Firefox, I have restarted my computer, I've cleared my cookies and cache history, but no websites will load and it will only run properly in troubleshooting mode. Oddly enough it won't load any websites but while I'm in the add-on manager I can download extensions.

Hi, current version is 100.0.2. Running on Win 10 (10.0.19044 build 19044). Have refreshed Firefox and also tried a clean install - problem still exists. Have done a scan using HouseCall - no gremlins found. For the last few weeks my browser has been playing up. After a few minutes pages would basically stop loading, clicking on a new link would open a new window but nothing would load. Disabled my Ad Blocker extensions (I had two) and issue resolved itself. Re-enabled Ad blocker (AdGuard AdBlocker) and problem returned. Disabled it, problem went, tried Ghostery (not used before), issue returned. Both extensions are recommended. Similar issue exists on my work computer - one ad blocker and after a few site visits pages no longer load, and links no longer react to a click, home button no longer works. I close and open and I get told firefox is already running and do I want to close it before opening again. Pretty sure it's not just my home computer. Any help would be welcomed.

Dear Firefoxers,

Over the last year or so, I've had to switch to Chrome to load some pages properly. reCAPTCHA is proving to be a particular problem - which I'm told is powered by Google? I could be blocking Google content too much within my Firefox browser?

My wife is a long-term Chrome fan and says, "I don't know why you bother with Firefox, Chrome is much better", but I rebuke and say, "No! It's been great over the years, I've been using it since 2003".

Do I need to change my settings somewhere? At times certain pages don't load - it'll say 'Click Verify; or something similar and the 'Verify' button doesn't appear - I load the same page in Chrome, and boom, it's all there.

Am I doing something wrong with Firefox? I have version 100.0.2 (64-bit). Or is it time to give in to the mighty Google and go to Chrome after loyally using Firefox/Mozilla since 2003? (A daft thing to ask on a Firefox forum, I know!).

Many thanks if you can help or advise.

I am still stumped as to why Firefox crashes, IF and that's a big IF, my session is restored, why my tabs are blank but the website names are still on the tabs. Click to reload sometimes works, while other times it doesn't. Google, Facebook, Twitter, WordPress websites I am logged into and others will not load anymore for at least an hour. The only way to access them is to open a private window. What is happening to this browser that causes these sites to not load anymore? Any clearing the browser history/cache doesn't bring these sites back. They will only come back an hour after the crash. I've also cleared my ISP cache too (ipconfig/flushdns).

Hi I don't know what has happened to Firefox, I used it all the time for many years, now I can't sign in to Outlook and have more problems than ever. It asks me to sign into Microsoft but all I get is a blank page. Firefox was always more colourful than other browsers that's why I used it and nothing you do to try to fix this problem doesn't work, it creates more problems than it's worth, that's why I use Chrome, but I do want to use FF. Not all of us are IT experts and can't do all these complicated suggestions every web site offers, so can you make it so much easier for us to understand and for example get Outlook to open automatically as it used to do, until you can fix this I will have to use another browser. I really do like FF but it's impossible. Geoff.
