Thunderbird has become a pain now for a number of months- regardless of any updates. On first start up if I click on anything on Thunderbird before ALL email accounts have completely finished downloading, Thunderbird locks up and displays not responding on the top of the screen. I have to wait ten minutes and longer before I can start reading a email until every email on every email account has finished downloading. When a site says it is sending a verification email - before I can see that email when I start Thunderbird - the verification email needs to be resent because it has run out of time. This never happened a year ago - now it is daily! I don't know what Mozilla is doing to Thunderbird but it is now highly unreliable! If it was not the only free email client software I would have dumped it by now. Why is it doing this?

After every update, Firefox starts to a blank screen and will not start loading the webpage url put in for over twenty minutes to a half hour. During this time other browsers on my Win 10 PC load immediately so it is not a network issue. It is Firefox. When I see that an update is pending I hesitate to do the update because I know I will lose the use of Firefox until it is ready to respond. It just hangs with "loading X.com" showing at the bottom left of the blank screen. I have been using Firefox for a long time and in the past year or longer it has become very unreliable. There are also instances where without an update it will do this and the only way I can get it to work is to clear the cache and the history through settings. What is going on with Firefox! (And lately there is an update every couple fo days!

Latest version of Firefox on Windows 11. When I click a 'call' button on a web page tel asks me to choose a program that will connect to my phone. Can anyone recommend such a program? Alan.

I have no idea why, but TB is wonking out lately with strange errors?

The folder '[Gmail]/Sent Mail on me@mydomain.com' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.

I have a ton of space and have not changed anything on the PC?

Any ideas?

Lately, there are an increasing number of sites that do not display or function properly in Firefox. The recommended browsers are Edge and Chrome, both of these do display these sites properly, neither of which are my first choice as I have reservations of these two collecting personal data with out permission (illegal data collection).

Google, gmail, you tube, etc SUDDENLY cannot load in Firefox on Mac but work fine in Safari on same Mac.

I get this message:Did Not Connect: Potential Security Issue

I have Firefox 139.0.1

This was working this morning but stopped in the afternoon. I use Duck Duck Go but I also tried switching to Google browser but got nowhere. Firefox loads everything else just fine. But no Google related sites.

I have deleted history, cache, cookies. Restarted the Mac. Closed and reopened Firefox. Again, all other sites accessed, just not anything related to Google.

I can see gmail on Firefox focus on my Ipad that is on the same internet connection as the Mac. This is really annoying.

Hello. I have noticed the following problem with your browser: at some point, if you have several resource-consuming tabs open (this is a subjective assessment, I have not tested it), almost all the buttons in the browser stop working, namely the tab close button, the extension button, etc., but you can still close them using hotkeys. This problem goes away when you restart the browser.

I should say that this problem appeared not so long ago, about 1-2 weeks ago, when I updated Fedora 40 --> Fedora 42.

Please tell me where the problem might be.

I cannot get my Roboform Ext. to appear when needed to sign into certain sites or use my CC within my Roboform for purchases! I have all of the areas in the private browsing area, but the Extension still does not work!

After installing a Firefox updated on Tuesday, I've been having multiple issues. The first issue I ran into was being unable to log into a work account that I have been using daily for 2 years. I was able to fix that issue by disabling the Enhanced Tracking Protection for that specific page. I tried that same fix for my other issue, but it is not correcting it.

I use a program called signNow to upload documents and send to people to sign/countersign. Since this update, it's not working on Firefox. I tried it on Edge and it works fine. When I upload a document, it's just blank. No text, pictures or anything at all. See attached screenshot. I've tried several documents and none have worked, but all of them have worked in Edge. How do I fix this so I can continue to use Firefox?

Hi, I've encountered a problem where if any error occurs when you try to create a new calendar event (I.e. Thunderbird cannot connect to the CalDav server), it will give you an error pop-up and discard everything you have input.

Losing work like this is extremely annoying and I think what should happen when an error occurs is that Thunderbird would go back to the event creation popup, preserving everything that was input into it, and let you try to create the event again (perhaps save it into a different calendar).

I'm not sure if this is the best place to ask about this but it was the most easily accessible place I could find.

This happened in Thunderbird desktop version 138.

Hi why cant i get my taskbar to show up on firefox on full screen. I used to be able to just put my mouse on the bottom of the screen to see the clock now i cant. ty

I have used Thunderbird and its diary for years, and make extensive use of reminders in the diary (my memory is not what it once was!). Latterly, when deleting or postponing a reminder, Thunderbird goes into "not responding" mode for many seconds or even some minutes.

I have Thunderbird linked to both my gmail and my protonmail email accounts. If I look at Task Manager when Thunderbird goes unresponsive it seems to be the connection with protonmail that is the problem - see the attached screenshot.

Help, please
