Greetings: Here is an error message that is now so common that I can no longer send email to any account. Also, I have not been able to send email to any gmail account for last year or two. Please help. Error Message:

"Sending of the message failed. An error occurred while sending mail. The mail server responded: <MattMcKeegan_PLS@proton.me>... Relaying denied: You must check for new mail before sending mail.. Please check the message recipient "MattMcKeegan_PLS@proton.me" and try again."

Thanks. Matt.

I use Firefox for years. Two days ago, I turned on my HP with Windows 10 and I got a pop up message something about Error Platform 126.0 XUL Runner is not compatible. I could not access Firefox, Google, or the internet. I uninstalled Firefox and reinstalled, but after that, everything runs very slow. Each time I go into a website, it can take up to over a minute to pull up! I checked all the trouble shooting forums in Mozilla and tried just about everything. I went into About:profiles and created a new profile. It it did not make any difference. I went back the profile I had before the XUL error because my bookmarks were there. Still slow. I cleaned out the cache, in both Firefox and my Windows 10. made no difference. I only have two extensions in Firefox. I don't know what else I can do to fix this.

Sadly, I am now forced to leave firefox. My passwords are getting "forgotten" more and more each day. Did i get hacked? Few passwords like proton mail I don't actually have anywhere else. Auto-Backup of firefox seems to be of the same day as the original??? So it loses the data then saves it twice? who designed this? I'm angry, not at firefox/mozilla. angry at myself for putting my trust in the first place. Chromium doesn't sync so it leaves me with chrome FFS. Does someone has a magic wand to recover the lost data? login.json is same day as original so not an option.

Tēnā koutou (Hello everyone),

I deleted Firefox to re-install it after playing with profiles and that not working how I wanted it to (yet). I uninstalled the app from the applications and the library on my Mac and reinstalled Firefox. Now when I open Firefox it says that it's up and running but no windows actually open up for me. I have uninstalled and reinstalled it again and it still won't open windows. I have to force quit Firefox as nothing shows up in my top tool bar to even show Firefox as open.

How can I get Firefox to actually install and be functioning on my computer again?

Running (as of an hour ago) macOS 14.5 (was using previous up to date OS when I installed Firefox again.

TIA

I need to go over the head of the Mozilla Triage manager who has left https://bugzilla.mozilla.org/show_bug.cgi?id=1406865 open without a resolution for **seven years**. How do I do that? This is a bug reported in Firefox 57 and **still** not fixed in Firefox 125. I cannot find any support category anywhere in the Mozilla website that covers appealing a decision by one of their employees. The last comment from this uncooperative indivisual is "But given we support it on macOS and Windows yeah, it seems not very objectionable." Who is this **clerk** to override the fact that a number of customers very much find this "objectionable". I cannot find anything on https://www.mozilla.org/en-US/contact/ that addresses this issue. I cannot find even a surface mail address for Mozilla. For example my complaint has nothing to do with any of the following:

   I’m having problems with using Firefox
   I want to donate to Mozilla
   I have questions about using Mozilla’s trademarks
   I’d like to report misuse of a Mozilla trademark
   I want to hold an event in a Mozilla space
   I want Mozilla to sponsor my event
   I’d like permission to use a Mozilla logo
   I’m interested in Pocket’s sponsored content on Firefox
   I’m a member of the Press and have a question for Mozilla

Yes I am having a problem with Firefox, but the clerk responsible has, through sitting on this issue for **seven years**, basically told the entire community that he doesn't give a reservoir.

In particular I feel this unacceptable behaviour should be brought to the attention of senior management, but there are no contacts for anybody in senior management.

My Thunderbird cache is using a gigabyte of disk space. I'd like to clear it, but it's not clear to me if I would be wiping out stored messages when I do that.

I like to download my emails to my computer (and keep copies on the server, too). I thought that was what I was doing, since I can view my emails when offline, but maybe I'm just accessing the cached copies?

Will I lose my old emails if I clear the cache?

ALERT ! wish to report an avalanche of emails from godaddy that are overwhelming my email box Tons of email under different names are coming from @registry.godaddy every day, the Junk filter is bypassed. A robot must be sending these one-liners using the flood volume as an attack. HELP!

Hello: I’m running iOS 17.3.1 on iPhone. The problem I’m experiencing: I used to see the Recommended by Pocket articles on my iOS Firefox homepage, but they stopped appearing a few weeks ago. I’ve searched for a resolution, but all I can find are the steps for customizing/personalizing my HomePage: the problem is that although I’m signed into my Firefox/Mozilla account and have chosen Firefox as my Homepage for New Tabs, and I’ve signed out, restarted the app and changed my Firefox settings several times, the option: ‘Recommended by Pocket’ ( along with the actual articles appearing on the homepage) doesn’t even appear anymore: I’m at a loss as to locating that option, as well as, again, seeing the Recommended Articles as they appeared previously. Thanks so very much for any help !

On my Android phone, the "close private tabs" notification keeps reappearing no matter how many times I tap it or swipe it away. Only way to get rid of it is by force stopping Firefox. Weird thing is that this issue doesn't repro 100% of the time either.

This is happening on Firefox 126.0, on my S23 Ultra running Android 14/One UI 6.1

Hi when i have to download my bios updates i am being forced to use misrosoft edge or chrome none of which i use , so the question is can i use firefox safely thanks . Lee

Mozilla's Android app has extension support but Mozilla's iOS app doesn't, I don't know why, I don't want to use Android, the only feature I miss on Android is this Firefox feature.

Hello, my Cox email account was migrated to Yahoo mail. I can receive emails but now I can't send emails from Thunderbird. I've triple checked server settings. Please help. Thanks-Vince

This is the message I get and it does this with all email addresses.

Firefox recently 'crashed' on my desktop PC. It asked me to restart in safe mode or restore to the original state. I chose to restore. This meant that I had to re-add all of my add-ons and log back into my favourite sites as my log-in details had disappeared. I got everything back to normal eventually, except for one very important site. I am now no longer able to log on to my bank website to review my accounts. I get an error message on the site saying " Log on error. You need to enable cookies in your browser to logon to Internet Banking." I have never had this problem before. I am able to log on successfully on my tablet, and also via a different browser on my desktop PC. I'm not a tech expert so this is very frustrating. I've tried clearing cookies/cache/data in the settings but no success. I really need to access my bank accounts on my desktop as I find this easier. Hopefully you can help as I don't want to use a different browser.
