Firefox Support Forum

I have a similar. but not identical issue email link issue; since last two Firefox updates, clicking on email links evoke the error message: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." and prompts me to close Firefox or quit. How do I fix this?

A few minutes ago i tried to access my email. On clicking the blue email address symbol it came up saying that this Thunderbird exe was no longer applicable. On trying to gain an answer from Thunderbird the blue email symbol simply vanished from its usual spot on the bottom. I now have no email access in any way. Thunderbird has kindly offered to send me a new access code to let me in. They apparently have failed to notice that to get an access code I need an email. Who nicked all of my mail and all of my access? Nothing else seems to be missing on the computer - well, so far?! I have not the faintest idea as to how to resolve this mess. Anyone help? Please ?

updated latest upgrade in Sept. since then cannot get games to play or they crash immediately, have updated adobe flash player like over a dozen times, security all updated a few more times, quick time player updated followed your page instructions. adobe flash player crash bar appears about every minute, even though videos usually play. does not have report crash box most the time. cleaned out unnecessary stuff, and also thunderbird mail will not let me get into it even with last password and when I try to change it, your site claims it has sent link to my yahoo mail which it never does, not in spam either and I tried that like 10 different times, so that is now working either. I am not a techy person, but have used computers since 2005 and have never had a problem like this when I have upgraded mozilla in the past. thank you, Deborah.

My OS is Win7 ultimate 64-bit. I have both Mozilla 40.0.3 and Thunderbird 38.2.0 as default browser and mail client, resp., and set Thunderbird to handle all protocols it can manage through windows control panel. Nonetheless, when I click in Firefox onto a mailto: link nothing happens. Any idea of what could be wrong? Thanks Dario

I have one outlook account and hone hotmail account. When the outlook account receives new mail it moves the read messages to the deleted folder. This does not happen with the hotmail account.

I use Mozilla Thunderbird for my e-mail manager. I have AOL and Yahoo mail accounts that I manage via Thunderbird. The new security requirements from Yahoo and AOL require me to remove my e-mail accounts from Thunderbird and add them back into Thunderbird. After I add the accounts to Thunderbird, the system then has me login to the Yahoo mail account. I am getting an error message that says my browser (in my case, Firefox) is not allowing cookies. I have changed all of the Privacy and Security settings that should allow cookies (according to Mozilla Help) and am still unsuccessful. I am at a loss on what I am supposed to do to allow cookies.

One of my folders in Thundrbird labelled "Archives" is displaying a closed vertical closed belt over it. I cannot open a subfolder of "Archives" to reveal other subfolders.

Start apps and either pages do not load or email does not download pop or imap. Closing both apps provide and error report.

Please note that when I was reviewing these errors on Friday, I noticed a reference to Cisco VPN. I uninstalled/reinstalled firefox and Thunderbird without luck. I thn uninstalled the Cisco VPN client app and both your apps started working. Now today, the apps started failing in the same manner and I have not installed any new apps over the weekend.

Thank you, Tim

My employer's default browser is Internet Explorer, and her default email client is Thunderbird. Up until four weeks ago the "send link by email" in I.E. worked fine. It now starts Thunderbird, but does not launch the WRITE dialog box, nor does it pass the URL to Thunderbird.

Firefox on her computer, using the "Send via email" menu option correctly launches Thunderbird's WRITE dialog box and correctly passes the URL to the new message.

One query for this problem is found here:

https://support.mozilla.org/en-US/questions/1157553

The suggested fixes do not work. MAPI appears to be functioning fine on the computer: Firefox (not the default browser on her computer) links to Thunderbird (is the default email client) fine, but Internet Explorer (which is the default browser) is not working properly. I have already done the suggested "fixes" that tens of thousands of people have suggested--- changing default software.

When Thunderbird and Firefox automatically install updates, there are always previous versions remaining under 'Programs and Features' in the Windows control panel. Since my HD only has little free space left, I'd like to ask whether it's save to uninstall these remainders?

Furthermore I realised that at least Thunderbird exists in two independent installations on my PC When I set up the PC, I installed all my programs in a path called C:\_P_Programme. Here the most current installation (V: 45.1.0) exists in C:\_P_Programme\E-Mail\Thunderbird. In the Windows standard path (C:\Program Files (x86)\Mozilla Thunderbird), there is another installation (V: 38.0.5), which can be started independently from the other one.

I installed Thunderbird and Firefox only once and afterwards only relied on the automatic update, so I don't have an explanation for this.

I use Windows 8.1 Pro.

Thank you for your reply.

The Thunderbird InBox shows a new item every few seconds or minutes. Duplicates of entries appear. This happens without apparent reason or trigger. A clean installation of Ubuntu 13.10 was done and, using the built in "software center" of Ubuntu, Thunderbird was installed. There was an appreciable backlog of E-Mail that was downloaded (400 items) and then the number of items began to increase when the operator began to delete selected messages. E-Mail items have grown to over 1000 without any new messages being received. Emptying Trash or doing additional deletions does not improve things. Settings have been reviewed without identifying any abnormality. The server setting is POP. No additional plug-ins, applications, etc beyond those intrinsic to Ubuntu 13.10 plain installation.

Assistance will be greatly appreciated.

When I click a web link from a email message (Thunderbird) or any other web link, , I get a wait circle from Win 7 for about 10 seconds but the page never loads in Firefox, but a firefox.exe process starts up. I can do this 10 times and the tab never loads the web page but I will get 10 Firefox process running. If I exit Firefox, all those 10 processes remain running and I need to stop them all before I can start up FIrefox again. I did startup Firefox in Safe mode and without my virus program running - no change. Extremely frustrating.

I no longer have the time to constantly close down Firefox given the number of times it totally stops when browsing.

I am not sure whether this is because of gradually changes to the browser or because of the increase in the number of websites that are now media heavey.

In the past I could regularly check news sites and leave tabs open to be able to compare articles etc..

This has now become a daily ordeal. One newspaper web site I am forced to use chrome.

Worse still the bloated use of memory is compounded by the excesses of Thunderbird which now also hangs and sometimes stops all processes.

What has gone wrong?

I am still using the same computer system with Windows 7 professional and Office professional.

But over the past 4 years Firefox and Thunderbird performance has dropped.

Currently having only just restarted Firefox is it consuming 143,972K and Thunderbird 86,696K also just restarted.

By comparison Chrome is using 60,000K and Internet Explorer 12,372K, while Outlook is using 7,872 (ie a 12th of Thunderbird) and Eudora 5,356 (a 13th)

Have followed all the various options offered over the past year for solutions. Nothing seems to return Firefox to being the reliable, and for me preferrable, browser.

Hello Everyone:

I have asked a similar question in the Thunderbird area.

My bootup is normal and I can open Thunderbird and Firefox (Ubuntu 16.04) All the tool bar navigation links on Firefox an frozen until I do the logoff/logon procedure. This is after a fresh, clean install. The same problem existed before the install.

Thunderbird will download all emails, but I cannot access any email until I logoff and logon the desktop. Thanks for any help.

Using Outlook Express, we find that some emails can't get in and others don't go out, even though there is no error message that alerts us to their non-delivery. Our ISP is windstream.net and their tech support says that the problem like with mozilla. How do I fix this? We have no way to know which emails don't go through and no way of finding out which emails don't get to us unless the people involved contact us and at least three have done so. Please help! Thanks.

There is detailed answer in support about returning to single space bookmarks. However, When I go to Preferences >General in Firefox, there is no info about HTML, no box with wording to unclick. Help? Where is it?

I use Thunderbird. I checked and Thunderbird is designated in my mailto action.

Today I clicked on the same email, clicked on the same link, and it opened in FireFox.

When I first got the email and it would not open in FireFox I right clicked on the link, clicked on "Copy Link Location" and pasted it to open the link.

Can you tell me what is going on?

This is not the first time this has occurred.

It was OK until a few days ago but now no links work in either Thunderbird or Windows Mail. I have changed nothing so I can only assume that this is another case of an update changing things without my knowledge. Links within web pages still work. Firefox is the default browser and we have been using Windows Mail and Thunderbird (gmail and googlemail) for at least a couple of years on this computer.
