Firefox 129.0.2 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

Running on kubuntu Linux 24.04, kernel version 6.8.0-41-generic (64-bit) KDE Plasma Version 5.27.11 Qt Version 5.15.13

I've posted a description of my problem on the kubuntu forums: https://www.kubuntuforums.net/forum/newbie-support/help-the-new-guy/681835-firefox-eating-up-a-lot-of-cpu

Here is a synopsis of my posts on that thread to distill the most noteworthy symptoms:

I have snap Firefox installed.

$ snap list Name Version Rev Tracking Publisher Notes bare 1.0 5 latest/stable canonical✓ base core22 20240731 1564 latest/stable canonical✓ base firefox 129.0.2-1 4793 latest/stable mozilla✓ - firmware-updater 0+git.5007558 127 latest/stable/… canonical✓ - gnome-42-2204 0+git.510a601 176 latest/stable/… canonical✓ - gtk-common-themes 0.1-81-g442e511 1535 latest/stable/… canonical✓ - snapd 2.63 21759 latest/stable canonical✓ snapd thunderbird 128.1.0esr-1 507 latest/stable/… canonical✓ - $

If I start firefox from the shell command line, it runs fine. It runs the shell script in /usr/bin/firefox, which ultimately executes /snap/bin/firefox. Clearly that shell script is doing some configuration that I don't understand.

If I​ hit Alt-space I see the menu in the referenced screen grab (see attached).

If I select the first entry, to run firefox from the command line, it has the same effect as starting /usr/bin/firefox from a bash shell; it works fine. However, if I select the third entry, firefox does not play any video; I've mostly tested with YouTube videos that have actual video and audio.

I'm not sure what gets executed when I select the third option from the Alt-space menu. It appears from doing a "ps -ef" that it's the same /snap/firefox/... executable. But I'm wondering why is this entry in the Alt-space menu and how does it get initialized or 'configured' to run.

Additionally, if I do start firefox from the entry with the firefox browser icon, and it fails to play video, I must then uninstall firefox using snap and then reinstall in order to get video playback to work. That is, after a failed start, simply exiting firefox and restarting it from the shell command line will not work; firefox will not play video correctly at all.

I also noticed that on my PC desktop, "snap list" lists firefox as "firefox 129.0.2-1 4793 latest/stable mozilla✓ -"

But on my old Lenova laptop running the same kubuntu version, "snap list" lists firefox as "firefox 129.0.2-1 4757 latest/stable mozilla✓ -"

​I'm up to date on both systems via "sudo apt update"' and "sudo apt upgrade"

Even more frustrating, today, for the first time, despite starting firefox from the command line, video still didn't play. I had to uninstall firefox and reinstall it.

I have been running into issues if Firefox affecting other programs. One example - closing a game from the big fish game manager. Normal termination of the game hangs up. Closing firefox, usually via the windows task manager, frees up the game manager and the game properly terminates. However, before having task manager close firefox, I see a number anywhere from 6 to 12 or more - firefox(10) for example - trying to re-launch firefox gets an endless round of messages about firefox not responding and a request to close firefox. So far I have only found one effective workaround to this issue. Booting into safe mode and clearing temp and prefetch. This usually holds but I have been seeing this every day for the last 4 days. What is going on and how do I fix it?

I am unable to login to Spectrum.net. I was able to login until a couple of days ago. I can login through Edge but I don't want to use Edge. I contacted Spectrum and since I can log in through edge they say it is a browser problem.

Hi, I try to visit my website ahsapsaksi.com. When I visit on firefox(Desktop and ios). I see the isimtescil template which is the old version of the website. However when I access from another browser like opera I see the updated website(welcome to acme page) only with VPN connection. I tried to delete cookies, visited in private tab etc., however I couldn't manage to see my updated website in firefox(in both desktop and ios).

Can you help me please?

Now a new update. When I visit the website on firefox with VPN connection, I saw the updated version, and from now on I cannot see the website without the VPN at all. I dont understand what is going on. But I tried to clear that cookie many times. Now it looks like the cookie is deleted not by deleting in the settings but using VPN. Now the problem is I cannot visit the website without VPN. Can you explain my experience? why did it happen?

I've been experiencing issues with my firefox browser (most updated version 129.0.2, running on Mac Sonoma 14.6.1). Seemingly at random times, it decides to start displaying weird symbols all over. The settings, the menu, the text on webpages, it all reverts to these weird symbols. Restarting the app and my laptop works sometimes, but only for a little bit of time then a day or two later this starts to happen again. I've tried to look at other help articles but it doesn't seem to be a font thing, it's becoming really frustrating and I hope there's an easy fix otherwise I won't be able to keep using this browser as I share my screen for work often.

This is what sows when i try to get newsmax.com I tired newsmax.com but get the same message as below.

Secure Connection Failed

I always been able to connect w/newsmax.com - until now. When it does not connect tells me to contact that site. Well... I tried and I can not get in to let them know. How do I fix this problem? Thank you in advance for your assistance and reply. Sandra

When using the Firefox browser I find that You Tube videos freeze up after a short while, and the whole website becomes unresponsive. I do not have this problem if I use the Chrome browser, so apparently the problem is specific to the Firefox browser.

After running scannow and chkdisk on my Win 11 laptop, the fonts for menus and toolbars in Firefox (not for web pages) is unreadably small (about 6pt). I have tried adjusting layout.css.devPixelsPerPx, ui.textScaleFactor, and browser.display.os-zoom-behavior to recommended valus as well as above or below values. So far, no help. Please advise.

I switched to Firefox from Chrome recently. When I attempted to login to Facebook using Firefox, I got a message that FB had deleted my account for violating community standards. However, my FB account is still active and accessible when I log in using Chrome. I deleted Firefox, then reinstalled it, but I still get the same message about FB on Firefox -- that my account has been deleted. Can anyone help?

Working on an iMac:

Yesterday, the Firefox browser started running insanely slow. So slow that we couldn't begin to use it anymore. We had to reinstall the Firefox browser a few times to get it working again.

Also, the Firefox Dev Edition browser, randomly crashed. Since then, it hasn't opened once for me. I've reinstalled the browser multiple times. Each time I attempt to open it, nothing happens, so we have to force close it.

Until today it worked fine. But now whenever I try to login to Xfinity I get You don't have permission to access "http://login.xfinity.com/login" on this server. It works fine on Chrome and Edge. I have disabled my add-ons. I have cleared cache, cookies, etc. I have rebooted. I have turned off firewall. I have checked my DNS. I have changed the DNS protection to OFF in Firefox. I have checked my proxy setting (I have no proxy). I have reinstalled Firefox. Etc. Etc. Nothing works. The fact that it works on Chrome and Edge, that it has worked everyday until today gets me confused. I also tried using my mobile phone as a hot spot to make sure it wasn't related to my Internet connection or IP address. Anyone have any ideas?

Have a new 2024 macbook pro m3 max with 128GB internal memory, 8tb ssd, macos (meest recente update) , and glass fibre internet connection of 1gb up and 1gb down and have used the same router and same ISP.

i use firefox in combination with nordvpn and multicontainer add-on to open multiple tabs with on each tab/containter the same video stream of 720p/3mb. Used to work perfect until a few weeks ago. In the beginning there is no problem, but after a while stream start to stutter and freezes completely and i get a blackscreen;. Tried every quick fix on the internet, and even increased the cache. Also tried different machines and issue is the same on each macos device.

how can i fix this?

Many thanks for looking into this.

Hi everyone,

I am trying to view streaming live broadcasts in my country's public TV but the site detected some HDCP issue and asked me to use a HDCP-certified HDMI cable. Here is some quick info and what I had tried:

+ Besides privacy reasons, I am unable to share the website address, as viewing is limited to my country's IP addresses by the national broadcaster. + I have a dual-monitor set up to a Windows and a MacOS machine, both installed with Firefox 129.0.2 with add-ons being synced. + Viewing live videos on the same website in Windows Firefox (HDCP-certified cable) has no issue but not on MacOS Firefox (same HDCP-certified cable but different HDMI port on the monitor). + Switching around the different HDMI ports and cables yield the same outcome. + No issue on either Windows or MacOS when viewing recorded videos though. Only live streaming on MacOS is affected. + Tried disabling all add-ons and toggling DRM but to no avail. + Checked Widevine is latest version (4.10.2710.0).

Appreciate any advice or help please. Thanks in advance.
