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.

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 know from visiting other forums that updates to Firefox have been released, but MSIX is not installing them - or even notifying me, much less asking if I want to install them. For example, Help > About Firefox shows that I am running V.129.0; yet I'm pretty sure that V.120.0.2 has been released.

Why? What can I do to ensure that I'm running the latest release?

I've restarted Firefox to see if that would work. It did not. I haven't rebooted to see if that works; but, even if it does, that seems to be a rather drastic effort to install a new version.

My RoboForm Mozilla add-on stopped working and I tried to uninstall then reinstall the app. When I try to reinstall the extension, the following pop-up occurs: RoboForm Start Page has detected RoboForm browser extension but cannot connect with it. Please update RoboForm browser extension. How do I update the RoboForm browser extension? Thanks for any help you can provide to resolve this issue.

After some of the recent updates, my entries into the url search bar work for 1-2 searches, then the search bar no longer functions until I close out firefox and then re-open it. Then, again this repeats itself each time I use the Firefox search bar.

I use Sync on multiple computers for passwords. I have forgotten the Primary password on one of them. If I do a password reset on the one computer, does it affect the passwords stored on the Sync server, or maybe just the key4.db and logins.json folders on the computer being reset? I will not do a reset if the Sync'ed passwords could be affected, I'll just look them up on my phone. Thanks for your 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?

cnbc.com will not allow me to sign in to my account. They want me to disable ad blockers, etc., except I don't have any ad blockers installed. Other times they deny my sign-in saying RECAPTCHA validation failed. I don't know if it has something to do with Mozilla Firefox or my virus protection (Bitdefender and Malwarebytes). The problem doesn't come up if I use another browser, like Google Chrome.

Across the top of my screen every one of my tabs just reads DuckDuckGo.

Instead of having the DDG logo and then the search I entered when the new tab opened, there is now no way to see what is on the tab. Even when I hover over the tab it still just says DuckDuckGo.

When I click on the plus button to add a tab, the tab opens with a blank page, which is how I have it set up. The logo on the far left of the tab is for Firefox.

DuckDuckGo is my default search engine, so after I type something into the search bar at the top in Firefox, the results are displayed from DDG, and the tab changes from Firefox logo + "New tab" to DDG logo + "DuckDuckGo".

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.

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.
