This is a recurring problem. I have just been on to Vodafone who have tweaked my router as my speeds, download and upload, were very erratic, and upload speed often zero so connections failed. Sometimes my phone speeds were similar but not always. The Speedtest by Oopla desktop app also showed erratic results but often when they were OK the web-based test on Firefox was much worse, with upload speed zero. When I started this Firefox showed upload speed zero. Now Firefox shows upload 18Mbps. This variability keeps happening and is driving me spare, as even emails often fail to go through - I use Thunderbird. I shall see how things go tomorrow and tell you how it is going.

When a bookmark is made, there is no option anywhere to add tags using windows 11 - I had no problem with tagging bookmarks using Firefox in windows 10, but that option is not showing up for me in windows 11. I have refreshed Firefox with no success to try to correct this situation - thanks in advance for any help you may provide – del

Hello,

I see with windows Firefox version 118 a TLS extension id 65037 on every client hello handshake containing a bunch of data. Does somebody know what this extension is used for? I couldn't find anything about this on the web or in the firefox docs / release notes. Other browser (chrome / edge) don't have this extension in use.

Thanks

Firefox just turns into a black screen and becomes unusable. It has been happening for a long time now and i have checked RAM and CPU usage and they are all fine, as I explored potential causes.

I will be using firefox and it just turns all black on all screens and is completely unusable. To use it again I have to force close all windows and reopen it and it works again.

This is a frequent issue that I have seen

Hola. Mi ordenador tiene Debian 12. Utilizo Firefox 118, instalado a través de Flatpak. El problema que tengo en algunas páginas es que veo las fuentes pixeladas y la impresión es muy defectuosa, hasta el punto de no entender lo que aparece escrito. Esto sólo pasa en algunas páginas.

Si descargo directamente Firefox desde la página de Mozilla y abro la paǵina con una configuración limpia del navegador, las fuentes se ven correctamente; sin embargo, si sincronizo los datos de usuario, instalándose los datos, extensiones y demás las fuentes en determinadas páginas se ven mal.

Desactivé las extensiones pero el problema no se resuelve. Desde una instalación limpia de Firefox instalé una a una las extensiones y complementos, pero no logré reproducir el problema. Borré incluso la caché del navegador, pero nada. Y también sincronicé los datos de usuario en una instalación de Firefox en Fedora, pero el resultado es también negativo.

Alguna idea?

Gracias.

Hello:

I must use the magnifier that came with Windows or I cannot read the screen. All was fine until Firefox updated. Now, when I try to use the magnifier, Firefox and all the sites I am using freeze. The entire screen fades out, and an hour glass shows up. But nothing happens after that. I have to go to the task manager and close Firefox, then start it up again.

I checked for Windows updates and everything is current. I am using Windows 10.

How can I fix this?

Is there a main location where Firefox extensions (like Forecastfox) keep their settings? If so, or if you happen to know where Forecastfox in particular keeps its settings, I could use some help locating this folder. I have a settings file I could put in there to overcome some difficulties that the folks at Mozillazine can't seem to help with. (https://forums.mozillazine.org/viewtopic.php?f=48&t=2913287&p=14963740#p14963740). The folder I have is named Forecastfox.2023.04.22.21.11.51.txt

I want to report that spyware named FindItPro which I, foolishly, downloaded. Well, it's a virus, right? But no antivirus can delete it completely. It comes back and you can't find the source. So, there should be some problem in your browser that allows it to live.

I'll send you a website where I got it. [link to suspected malware removed] BE CAREFUL. Virus will be downloaded along with Opera browser or something. I'll send this report also to some antivirus company. Yes, I was foolish, but I hope you will fix it.

Hi! please help me lmao i'm not sure wtf is going on. I recently (as of a week ago) had to wipe my pc and reinstall windows 10 after a botched update. So i installed firefox on a practically new pc. thing is... when i turn it on, i get this baby in my taskbar (see image): right under the pinned firefox and thunderbird logo, i get a really scrungly OLD (and i mean OLD) firefox logo. clicking it opens nothing. hovering over it shows a preview of a blank window with a random string as title. clicking it only opens a second blank window with nothing in it. eventually when windows finishes starting up, it closes itself. i'm scared it might be a virus. help? how do i make it stop??

I'm running firefox 117.0.1 on windows 10 home single language 1903 (sorry if that's wrong, i dont know where to check otherwise)

Possibly there was an auto update of MOZILLA FIREFOX on our DELL LAPTOP (Windows 11). Now, we cannot get a Mozilla window to open - due to error message:

XUL Runner Error: Platform version '118.0.1' is not compatible with minVersion >= 118.0 maxVersion <=118.0

Can someone please help us get back to a previous version of Mozilla Fire. Perhaps it is a Windows error. I have no way of knowing. Please help me. My email is: [removed email from public] Thank you.

I have followed the steps in the "Prevent Firefox from starting automatically" article: https://support.mozilla.org/en-US/kb/firefox-starts-automatically-when-i-restart-window

But Firefox keeps starting automatically when I restart my computer. Attached is an image of how the settings are now.

What should I do? This is a bit annoying. I don't use Firefox as my main browser but I work as a customer success manager for an online platform and always need to do some tests on Firefox, but I don't want it to start automatically when I turn on my computer.

I'll for instructions.

Thank you

On a site with a menu along the top the rightmost item is missing, and only in Firefox, not Chrome or Edge. It happens on various pages with the same menu setup. I cleared cookies & cache, turned off extensions, no luck. See attached image. What could the problem be ?

Few days ago, some of our clients and few (not all) internal PC are get stucked on a PR_CONNECT_RESET_ERROR on our website. Only on 117 windows version (118 developer version and 119 nightly seems ok). We tried to repair firefox, it works on 95% but we can't ask our client to do this. It works on Chrome & Edge.

We running out of ideas : - we only accept TLS 1.2 / 1.3 - checking CSP - Both IIS and Apache are not working - Firewall are not blocking

Certain images are never created or loaded in my browser. Youtube thumbnails, for example, display as only light grey squares. I thought maybe my addons might be causing this, but the only one that seems capable is uBlock Origin, and I even disabled it completely. Anyone know what could cause this? Surely its a caching issue or something. I can include images if anyones curious.

As above

Why would they disable accessibility tools without even a notice?

What kind of monsters would do that for the sake of political grandstanding?

Any ideas why I am seeing these strange rectangles on Google maps?

Confirmed not caused by an extension as I still see them in Private window and do not see them when using Brave.

They don't stay in the same geographical location when zooming in and out.

I have several profiles. They all have the same Chrome folder contents, but only some of them have the "chrome_debugger_profile" folder.

I'm guessing I must have generated it along the way while tweaking the Chrome folder contents?

Hello!

I recently got a new computer with Windows 11 freshly installed. I downloaded Firefox, went to take a screenshot, and the usual shortcut of Ctrl + Shift + S does not work. I can right click and Take a Screenshot, and I can use other Ctrl + Shift shortcuts, like Ctrl + Shift + T to reopen closed tabs. The only one that doesn't work is screenshots. I can also put Screenshots in my top row Toolbar and use it, just not the keyboard shortcut.

I refreshed Firefox, uninstalled and reinstalled Firefox, as well as checked the about:config extensions.screenshots.disabled preference. It has been set to false, so I have set it to true and false again hoping it would "reset" it but nothing. Thank you!
