Firefox 技術支援討論區

After having the same password for several years, I am told my password is now wrong. I have tried to change the password, but am still denied access to my email. Is the problem with my user name that I have had for many years? What do I do to access my email account?

It's the same for other programms, for example Word. The focus of the programm (Thunderbird, Word ...) is lost after clicking, but Firefox doesn't do a thing. (Firefox is set as my standard browser). What can I do?

Thanks in advance!

control++, control+-, and control+0 all work as expected, but if I'm not quick enough to let go of the control key, or if I just press the control key all alone, the web page I'm on (including graphics) or the email body I'm looking at in Thunderbird just get larger and larger. The problem seems to be limited to Mozilla as the other browsers, Word, etc. don't exhibit this behavior.

I have no idea what combination of keystrokes caused this! I have rebooted.

Firefox and Thunderbird crashing, even in safe mode. I have refreshed and reinstalled. Removed all extensions. Same result. Crash ID: bp-d4b8f2e3-6bda-49a1-a3da-399be2161211

I use Firefox as my default browser and Thunderbird for my e-mail. I received an e-mail with 3 links in it. The 1st link opens in Firefox but when I attempt to open the next link I get a message "Firefox is already running, but not responding. The old Firefox must be closed to open a new window." I changed my default browser to Microsoft Edge and the 3 links opened into 3 separate windows. I have tried adding a profile and uninstalling FF and reinstalling (getting a new profile). Same problem. I am able to open multiple links/tabs on FF but not via Thunderbird e-mail. I am running Win 10.

I am filling in my profile haveing just downloaded Thunderbird mail system and one question is enter your URL and I can not think for the life of me what it is. URL

I can sign into Outlook via Firefox. Thunderbird regularly downloads messages from there. When I try to send, I get a Server Not Found error or sometimes Unable to find server. I have deleted the outgoing server and reinstalled it. I have checked all the settings and have never found an error. This is a new problem (a few months old), and it previously worked well. I am running Ubuntu 12. Accounts at Yahoo and gmail work well. I am using Thunderbird 12.5. I have also added another entry for this server but it does not work either.

64 bit Windows 10 Home addition, Thunderbird - Ver. 52.5.2 (x86 en-US) updated 01/05/18, Firefox v- Ver. 57.0 (x64 en-US) -system shows Firefox last updated 11/15/17. My PC has been wanting me to update Firefox, but I was telling it to remind me later for the last 2 or 3 weeks. I shut my PC down. 5 days later I turn my PC on, waited for it to boot, then started Thunderbird which automatically downloaded my last 5 days worth of emails from the server. My PC then froze. Eventually I powered down my PC and turned it back on. After it rebooted it asked me to sign in to Firefox to sync my devices. (I am assuming that it Firefox updated without my approval but it still shows the last update as 11/15/17.) After it completed the sync I opened Thunderbird again and found the last 5 days of emails were not in my inbox and Thunderbird will not download them again. It is downloading new emails when i receive them but not the ones it downloaded just before the freeze. Thunderbird is set to leave messages on server for at most 15 days and until I delete them. My question is how do I get Thunderbird to download the last 5 days worth of emails again without affecting all my other emails and without duplicating emails that were previously downloaded?
