Hello,

I'm facing a two-fold problem:

1. Firefox (138.0.4, 64-bits): when trying to open a website the URL is loaded in the FF-tab, but the screen stays empty

2. Thunderbird (128.10.0esr, 64-bits): downloading messages isn't possible anymore. When sending a message I get following error message (in Dutch):

Verzenden van het bericht is mislukt. Er is een fout opgetreden bij het verzenden van e-mail: fout met uitgaande (SMTP-)server. De server antwoordde: Cannot connect to SMTP server 127.0.0.1 (127.0.0.1:54601), connect error 10061.

Translated to English:

Sending the message failed. An error occurred while sending the email: Outgoing (SMTP) server error. The server responded: Cannot connect to SMTP server 127.0.0.1 (127.0.0.1:54601), connect error 10061.

I did a ping with following result:

C:\Users\<user>>ping 127.0.0.1

Approximate round trip times in milli-seconds:

I didn't make any changes to FF and/or TB, and my wild guess is that the necessary Mozilla servers aren't available anymore, due to:

May 21, 2025

If somebody could step-in, that would be great!

Recently Firefox has been hanging up more than usual, I did a double check on all drivers, updates, and virus protection. Normally things work fine but through the day I'll get the "Gah this tab has crashed. " Or the window will freeze and hitch up, sometimes having to be completely closed with task manager. Just wondering if this is something to do with firefox as a whole, my add-ons, or something I can fix with an easy reinstall.

Hello,

I am not familiar with how Mozilla Firefox

Two days ago, I had Microsoft Window 11 screen flickering issues. Searching the web for possible solutions, many recommended to uninstall any recently updated apps prior to when the screen flicker issue started. Since Mozilla Firefox was one of the recently updated apps, I uninstalled it but didn't know that I will lose all of the bookmarks I put under browser the bookmark ribbon.

I never saved or exported my Firefox bookmarks before since I thought it will be saved automatically. However, after I reinstall the Firefox app, my bookmarks are gone.

How can I get my Firefox bookmarks back if I never manually saved or exported the Firefox bookmarks before? I really would like to have them back. Desperately need help.

Thanks very much,

KT

I am trying to resolve an issue with my firefox browser for MAC OS. Everytime I close my screen to sleep and open it back up, the browser stays on time out mode. I have tried downloading the update, but it never seems to complete or fully initiate. I have gone to the mozilla website and downloading directly from there but the new download wont even let me log into my gmail.com using my biometrics. any ideas?

Just trying to watch youtube

Open a video, the little circle goes around for a second or two, and starts playing (but it's not synched with the audio - the video starts playing a second or two after the audio starts playing)

Close all other apps, clear cache, restart, same problem

But I do NOT have this problem in other browsers

Do I have to quit using firefox?

I have been experiencing a lot of lagging, lockups and closure when browsing. I use Windows Version 10.0.26100 Build 26100. My Firefox version is 138.0.3 (64-bit). While telling you about this issue, my systems has locked up. I had to wait for it to start again. I have had to use other browsers, Google Chrome and Edge to complete tasks. I am able to browse and do everything fluidly, without issue using those browsers.

I have noticed that certain website just do not work well with Firefox. I'm wondering why that is? For instance, Petsmart.Com. That's a popular website. I almost always have to complete my orders using a different browser. Is there anything that I can do about this? I'm really frustrated and getting ready to ditch Firefox.

Thanks for any help you can provide.

The virtual keyboard on my HP OMNI 10 tablet has begun popping up at every touch of Firefox. This makes it almost impossible to use. Expected/normal behaviour is that when you touch web pages or any app., the keyboard stays out of the way while you move around. When you touch inside a textbox, the keyboard should pop up so you can type. Touch outside the textbox and the keyboard drops down. Now, ( since the start of May 2025 or so, I think), the keyboard pops up every time I touch the Firefox page, anywhere. This makes it almost impossible to use.

For example, on a Youtube video, I touch the video to start playing.... and the keyboard pops up, covering up the video! I have to touch the x to drop the keyboard down again. When I want to rewind or move forward, I touch the video to get the controls to appear and...the keyboard pops up, covering the video. I have to touch the x to drop the keyboard and by then the video controls have timed out and gone away again!

Right now, if I close the keyboard and touch this page outside the textbox, the keyboard pops up.

In Microsoft Edge the behaviour is normal and in an app., like Notepad, the keyboard only pops up if I touch inside Notepad.

By the way, I did all this typing once already but when you said you couldn't read my troubleshooting information automatically, I tried your manual steps, and that took me to another web page. When I came back to this page, all my typing was gone! Very annoying. please don't do that again.

You guys do an update. Suddenly I can't open any sites. Top of the tab, a little set of dots go side to side foreverrrrrr. Do not, I repeat, do not ask me, "are you doing this, or are you doing that"......that's not a solution.

It's bad enough I have to use another browser to read FOX NEWS, cause your page refreshes non-stop.....

Oh and I used clear history, and my sites all want me to relog back in. Again, do not tell me to unclick cookies and stuff....

firefox stalls on ubuntu and the OS says it is running but I cannot or don't know how to restart/reset it from the terminal. A reboot of the computer solves the issue but I have to re enter the bios password etc. Is there a simple solution?

Hi Team,

When we enable Netskope, all the searches breaks (specifically with Google Search Engine). It takes about 2 to 3 mins to do the first search, after which it continues to work normally.

Furthermore, facebook takes too long to load (~4mins).

The netskope support team has asked us to make a few changes in about:config: 1. network.http.http3.enabled 2. QUIC protocol 3. network.udp.enabled

None of this works and even if it works, the problem is we have about 1500 devices.

Are there any reported issues ? And is there anything that we are missing ?

I have noticed a weird scrolling bug in Firefox since either v138.0 or v138.0.1.

If you go to https://www.architecturaldesigns.com/ and select any floor plan, if you attempt to scroll down the page the page will not let you and snap back to the top.

I tried this in Firefox troubleshooting mode with all add-ons / themes disabled and encountered the same behavior. This is something that just started happening in the last version release or two.

This is present both on Windows as well as Mac versions of the Firefox browser.

A major bug unfortunately means that Firefox cannot open in full screen anymore. I have tried restarting it more than a dozen times, but it still doesn't work. Please solve this as soon as possible; I am begging you, I’m on my knees for the developers.

After letting Firefox idle for a bit (like 5 seconds) and nothing playing on the screen, when I come back, it causes screen stuttering for my whole desktop. Disabling hardware hardware acceleration doesn't help much.

OS: Arch Linux x86_64 Kernel: Linux 6.14.5-arch1-1 Display (CMN1521): 1920x1080 @ 144 Hz in 15" [Built-in] WM: Hyprland 0.49.0 (Wayland) CPU: 12th Gen Intel(R) Core(TM) i7-12700H (20) @ 4.70 GHz GPU: NVIDIA GeForce RTX 3050 Mobile [Discrete]

I'm debugging some web sites, and I often need to reload a page to see if a change I made on the server works correctly. On iPads and Android devices, this doesn't seem possible. Yes, there are the circular-arrow buttons, but they only work with Firefox (and Chrome;-) on my MacOS or my linux server, but not on my iPads or Android gadgets. They act like they're doing something, but the page on their screen doesn't change. (With FF or Chrome on the "real" computers, it does change). The only advice I find online is to use CTL-R or something similar but those "devices" don't have CTL buttons. Nothing else I guess at works, either.

When I ask online, I get replies that work for linux, MacOS or Windows, but clearly saying "iPad or Android doesn't help; the answers don't apply to those systems.

Am I missing something? Web developers need ways debug their code or html or whatever they're working on, and this requires checking how it works on the actual users' screens.

Recently, after two Firefox updates, there are changes on my home page.

1. I only get the top bar and not a full page. I have to click on the green circle with the enlarge icon to get a full page.

2. No longer can access multiple pages on the home screen so cannot cut/paste or transfer and drop info onto different pages.

While I have Firefox as a browser, my search is usually done by google.

How can these problems be fixed.

Thank you.

From the last two Firefox updates, I no longer can move sites screens around on my Mac Air laptop. Only one page at a time shows up and consumes the screen. I am no longer able to copy and past and move info to another screen. A couple of weeks agom I cleared my cache but not sure that had anything to do with it. Please suggest solutions. Is there an add on or something that needs adjusting?

Thank you.

I delete all the old bookmarks that come up and restart and they come up again or Firefox completely freezes my computer. I tried to Refresh Firefox and that worked UNTIL I signed out and signed back in again. Then I get dozens of sites trying to open and freezing again.
