Lately, I’ve noticed Firefox consuming more RAM, especially with multiple tabs open. Is this a common issue in recent updates? What are some tips to optimize Firefox performance on lower-end PCs? Would love to hear your experiences!

In the last few days, the common Cloudflare widget required to login to many web sites has abruptly stopped functioning in my browser. I'm trying to diagnose what's caused it. I'd appreciate any suggestions or advice.

I noticed the issue on nexusmods.com, but I've confirmed it's a universal problem on ANY site that uses Cloudflare protection. I've continued to use Nexus as my test case.

Observed behavior: 1) The Cloudflare widget loads 2) It displays a checkbox noted, "verify you are human." 3) I click the checkbox. 4) It immediately begins "thinking" (spinny circle and "verifying...") for about nine seconds. There is an "error" message that appears during this, but no details are offered (see screenshot) 5) The widget reloads. 6) Go to step 2

This is an infinite loop.

Fixes attempted: - Disabling all extensions (uBlock, NoScript, Privacy Badger, Decentraleyes) - Clearing cache - Updating to the most recent FF build - Accessing in a private window - Changing DNS settings from Cloudflare to NextDNS - Disabling DNS over HTTPS altogether - Disabling HTTPS-only mode

With Microsoft Edge integrating Copilot and Google Chrome adding Gemini AI features, do you think Mozilla should follow the trend? Would you like to see AI-powered tools in Firefox, such as automatic tab organization or AI-driven search? Let’s discuss if Firefox should embrace AI or stick to its privacy-focused roots!

I have been providing auto-configuration information for my users. It used to work well but at some point it stopped working. When I try it on 128.7.1esr and create a new email account, the debug console shows me:

Thunderbird queries my web server using this URL: https://christoph-haas.de/.well-known/autoconfig/mail/config-v1.1.xml?emailaddress=footest123%40christoph-haas.de

My XML file:

<clientConfig version="1.1">

 <emailProvider id="christoph-haas.de">
   <domain>christoph-haas.de</domain>
   <displayName>Christoph's Mail Service</displayName>
   <displayShortName>ISPmail</displayShortName>
   <incomingServer type="imap">
     <hostname>webmail.workaround.org</hostname>
     <port>143</port>
     <socketType>STARTTLS</socketType>
     <authentication>password-cleartext</authentication>
     <username>%EMAILADDRESS%</username>
   </incomingServer>
   <outgoingServer type="smtp">
     <hostname>webmail.workaround.org</hostname>
     <port>587</port>
     <socketType>STARTTLS</socketType>
     <authentication>password-cleartext</authentication>
     <username>%EMAILADDRESS%</username>
   </outgoingServer>
 </emailProvider>

</clientConfig>

I fail to see any errors in here.

I even tried with the reference configuration from https://wiki.mozilla.org/Thunderbird:Autoconfiguration:ConfigFileFormat but it failed as well. (I just found that the <serverURL> tag is not properly closed but that was easy to fix.)

Has anyone here seen that effect as well? Should I file a bug?

Thanks for your time! …Christoph

I have two email accounts. One is about 2% of my email sending and one is 98% of my email sending. One of them is the default choice when I create a new message to send. Guess which one is the default?

How the absolute F do I get TB to re-order these so that I am not sending so many messages from the wrong address?

Do I need to set up a completely different profile for TB and only launch into that when I am going to send from the lesser-used account? What the heck do I have to do?

Hello, I would like to thank you, first and foremost, for taking a look at my issue. As for the issue itself, every so often, with increasing frequency, I am getting notifications from windows security about it blocking "firefox.exe" from accessing my "%userprofile%/documents" folder. I am not a tech savvy person so I don't understand what any of this actually means but I've been using Firefox for the better part of the last decade and this is the first time I've ever had something like this come up.

I've attached a couple of screenshots I took recently so maybe it'll offer some insight that I don't have the knowledge to understand.

Thank you for your time.

Dear Team After Updating from 102.15.1 (32Bit) to 115.28.0 (32Bit) I can not connect to the provider "pop.hispeed.ch" anymore. Ping pop.hispeed.ch (on CMD) shows normal raction of beeing reachable with a "reply from xxxx.". I am on Windows 7 SP1. I have checked several times all setting POP and SMTP, switched off Firewall, uninstalled virus scanner, and and and many more (all knowledge found on internet..). Pressing the "Get Message" button in the upper menue bar shows no raction when pressed. The icon "Get Message" on the left side of the button "+ New Message" results in a none moving blue status bar at the right bottom of the window. After a while with the message "timed out.. ".In the settings "Config Editor.." the values of "mailnews.tcptimeout" are set to "300", and "true". I am using TB since donkey years with many many eMails. Are the lost? Thank you for support and help, Andy

I have 4 Suddenlink emails being checked with Thunderbird. I have been running my current Thunderbird configuration for year. I have not changing anything on my end. Two weeks ago, I started getting a login to server pop.suddenlink.net failed popup on one of my Suddenlink accounts. I have logged into the email on the web interface and changed the password on the web and in Thunderbird. I am still getting the login to server pop.suddenlink.net failed. I have rest the password on the web interface a few times, but still cannot get it to work in Thunderbird. The other 3 Suddenlink accounts are still working fine. I have Thunderbird running on a second computer at work checking the same accounts and I am having the same problem with the same Suddenlink account.

I have thousands of blank emails in my spam folder that I can't delete. They all have no subject or correspondent, and the date is 12/31/1969 4:00PM. How can I get rid of them?

Is there anything I can do here, I was kind of on auto-pilot when I decided to reinstall firefox and didn't realise I it picked up from my "old account" So to speak and I didn't notice until after doing a bunch of set-up and I kind of panicked.

Leading to the situation I've put myself in which doesn't seem redeemable cause there's no way to get access back to the older account. As far as I'm aware. Its the Syncing deal. I didn't mean to sync and transfer stuff over to this old email (I'm hoping I didn't) but panicked that I did it anyway. Because Like I mentioned I was auto-pilot.

Since I have no access or way to get back into my other Account to try and resolve it what can I do if anything?? I can't reset the password because the email I used back then doesn't even exist anymore.

There must have been an update for Thunderbird that screwed up the way I have been using Thunderbird for years now. I had sub folders under inbox. For example, I had an investment newsletter go into a sub folder under inbox labelled "inv". I had a filter set up to move emails that had the name of the newsletter in the title to go to that "inv" folder. In this new version of Thunderbird, those separate sub folders are gone. The filters are still there but the folders are gone. Now all emails just go into the inbox. Is there a way to roll back to a previous version?

TIA Eric

Attempting to load a link via the Firefox Share Sheet's "Load in Background" option does results in no tab being loaded in the app. The share sheet function appears to function normally, but after switching to the app, the link is not loaded. No blank tab is created either; it is as if no action was taken. All other functions in the share sheet work as expected, just this one function.

I primarily use this function when loading links from newsletters in the Mail app, but I've observed it when using other apps, for example, the Drafts app.

The experience is exactly as described as in https://github.com/mozilla-mobile/firefox-ios/issues/12414 , just updated to today. The only differences are I am using the latest version of Firefox on iOS, and the latest version of iOS on my iPhone 16.

Is there a setting or issue I'm not seeing or need to check? Or should I open a github ticket?

Thank you in advance!

Two mailboxes are involved. Mailboxes ar configured as POP3. The problem started just a view days ago, as far as I can see shortly after 128.7.0.esr. Currently 128.7.1.esr is active but the problem stays.

I have no clue where to look.

Due to technical problems, I had to reinstall the system on my computer, losing files, and I also went back to Windows 10 instead of continuing to use Windows 11 because Windows 11 doesn't work well on my computer. after downloading firefox I logged in as always, after logging in it always remembered my passwords, bookmarks and so on, now it doesn't. I don't know what to do
