Dear Mozilla Community members,

For a while now I get sort of an error message some time after Windows start (every time): "XULRunner Could not determine any profile running in backgroundtask mode!"

I managed to find out that XULRunner is connected to Mozilla but I haven't found any info about this particular message so far, therefore, I would appreciate your help solving this issue.

Thank you in advance.

Kind regards, Ewelina

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.

Version 91.7.0 only allows me to send mail from one e-mail address, as all the smtp settings are now the same. Previously, each address could have different settings, which my e-mail provider requires.

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).

So weird, in the last few days, I've had intermittent behavior using FF.

Some examples - I log into my Gmail account, and it works for several minutes and then goes unresponsive and I can't get new mail, when I click the refresh icon or refresh the browser. - Last 3 days, when I click a hyperlink in an email, a new browser tab opens, but it's blank, the url doesn't seem to pass to the new tab - When I type a search term in browser address bar and hit enter, the tab refreshes but nothing happens... e.g. https://www.google.com/search?client=firefox-b-1-d&q=firefox

Troubleshooting steps tried. - Disabled all extensions - Started to uninstall FF, but got prompted to "refresh firefox" instead, which I did yesterday, but still have the same problems...

I can access Gmail and other functionality works fine on Chrome on same laptop. I've used different laptop with FF and it works fine, both machines on the same network....

I have asked this question before with a different subject title, and I am surprised there is no move to fix it. It is an annoyance that I expect effects many. So I am trying again with a new title and more explanation.

I have attached 3 images, showing a) how I have my folders layed out, b) viewing a group of my folders including my local folders, and c) the change in view after I rename one of the observed folders called "Amick." Instead of the view staying the same, so that I can see the name-changed folder in the folder structure, it reverts to the top of the structure showing all the favorites followed by the local folders.

What I would like to have happen is for there to be NO CHANGE in the view after I change the name of a folder or delete a folder, so that I can see what I have accomplished and continue working. As it is now, it is a big nuisance the time waster. Am I missing something that I can do to solve this problem, like some advanced setting?

Thank you.

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.

Has anyone received this message or know how to fix the issue that may be causing it?

After updating Thunderbird to the new version 91.9.1, most of my email messages disappeared.

An error message was displayed after updating to the new version. Thunderbird restart chashed and I started the program again, just to noticed that the messages were not anymore in the folders.

How can I recover my messages?

Our company email host uses Office 365 exchange. As of yesterday (26 May 2022) all emails were blocked to Thunderbird on our networked office PCs using Windows 10. We cannot send or receive email on Thunderbird (fortunately it still comes through to our iPhones). Our host hold us that Microsoft has "recently started blocking POP3 connections on software such as Thunderbird".

 How do we fix this problem so that we can continue using Thunderbird, which has our email records for some 10 years?  We do not want to use a Microsoft mail client unless we really have to!  I imagine we aren't the only ones with this problem, but I couldn't easily find it by searching help.
 Many thanks!

Hi!

I often send an email to 140 recipients via SMTP. Until recently it took 2-3 seconds. Now it takes about 2 minutes. My web-hosting company Simply.com is very insistent that their server is not the problem. I use TB 91.7.0 (64-bit) on Ubuntu 20.04.4 LTS. I am not sure whether TB updated itself when the problem started. Any help would be appreciated.

Im looking for help. TB deletes all email. I have an old backup email account. All file ...AppData\Roaming\Thunderbird in zip. Procedure: 0. delete all current file in folder ...AppData\Roaming\Thunderbird 1 unpack archive 2 open Thunderbird 3 turn on offline mode 4. read old emails, all emails are there. 5. clos TB 6 open TB 7. all email is gone !? Why? This is terrible. Why does it delete all emails without asking?
