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.

LINUX. see subject, please. i started on this laptop w/ mint. 5 or 6 years ago. then downloaded peppermint 1 and has been working great, but the browser does not update automatically like is said. Then, my Linux guy up and passed away. I know no one in town that uses it. I'M ON LINUX. any help appreciated. have gotten some replies with folk trying to help, but it just wants to download/install whole program. my bank wants me to upgrade to at least 115. can't access accts. Chase are useless. They don't know what Linux is. Perhaps someone here can point me in right direction? Regards. God bless.

Over the past few weeks I've been unable to watch live videos on Firefox on Ubuntu 22.04. I thought it was just an issue with Twitch but I realized the problem also persists on live videos on Youtube and did some troubleshooting which didn't solve the issue. The only solution I was able to find for Ubuntu said to install ffmpeg, which I already had, but I made sure it was upgraded, refreshed Firefox, and still have the issue. Currently I'm on Firefox 121.0 but I've had this issue since before I updated it. I dual boot Ubuntu and Windows and am not having this issue when I boot Windows on the same computer and Firefox profile.

Firefox for Linux has a bug where it is unable to drag a tab from a non-active window. As in, if the window focus is on Firefox window A and I try to drag a tab from Firefox window B to window A, I have to click first the window. I can't just intuitively drag the tab from a non-active window, because it will get ignored. It will just activate the window, ignoring the drag.

Firefox for Linux, running on Nobara KDE latest desktop. Confirmed also on KDE Neon latest desktop.

Hello, I imported Bookmarks when I came to Firefox from a previous browser. The experience was terrible and challenges still linger. Firefox has come a long way, however UX still seems to be a 2nd class citizen. Bookmarks now has somewhat duplicate directories and this in turn is causing desktop/phone sync doubt and is likely missing bookmarks.

When sync breaks, it is so confusing. How can I simply have a working Bookmarks sync on desktop/phone?

Perhaps there was a challenge when I need Bookmarks to appear in the top bar when a new Tab is opened, as this was contrary to default Firefox settings.

In case anyone's interested, under Debian 12, when I resume from hibernation, if I have Firefox running as well as Tbird, if I click on a link in an email, the existing instance of Firefox is ignored and a new instance is opened. The first instance is in fact frozen -- it looks as it should but trying to change tabs or open a new tab is inactive. Seems I have to kill the open instance of FF, then if I click on a link in an email, FF pops up as it should with a new tab for the link, but the existing tabs are all there and all functional. It feels like a bug -- Tbird seems not to know that FF is already running.

I am trying to use a <select> tag to display a color selector. So each <option> has a background color to match its displayed text:

```<select id="strokeColor" name="strokeColor" style="width: 10em;">

             <option value="black" style="background: #000000; text: #FFFFFF">
                     black
             </option>

<option value="aqua" style="background: #00FFFF">

                     aqua
             </option>

<option value="blue" style="background: #0000FF">

                     blue
             </option>

<option value="brown" style="background: #A52A2A">

                     brown
             </option>

<option value="gray" style="background: #808080">

                     gray
             </option>

<option value="green" style="background: #00FF00">

                     green
             </option>

<option value="magenta" style="background: #FF00FF">

                     magenta
             </option>

<option value="orange" style="background: #FFA500">

                     orange
             </option>

<option value="purple" style="background: #800080">

                     purple
             </option>

<option value="red" style="background: #FF0000">

                     red
             </option>

<option value="white" style="background: #FFFFFF">

                     white
             </option>

<option value="yellow" style="background: #FFFF00">

                     yellow
             </option>

<option value="#000000" selected="" style="background: #000000">

                     #000000
             </option>
         </select>```

On Chrome this displays as expected:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-04-18-22-02-25-eebbd5.png

But on Firefox the background colors are ignored:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-04-18-22-02-35-bd90ee.png

How can I get Firefox to display the background colors?

I've installed Nightly the same way I have for years on my latest Fedora 33 install—i.e., download tarball, extract into /opt, set appropriate chmod and chown, make .desktop file, etc.—but certain videos certain videos on certain sites refuse to play. A Fedora discussion discussion led me to think it's how Fedora 33 may sandbox apps; I haven't yet had any hits on solutions in the Fedora groups, so I thought I'd ask here, since I can't be the only one with this issue.

Any help would be greatly appreciated!

On bootup firefox opens a single window which says the following:

Sorry. We’re having trouble getting your pages back." We are having trouble restoring your last browsing session. Select Restore Session to try again.

The restore function succeeds in restoring 6 windows from the prior session, but this notice keeps appearing on every bootup.

Here are a few relevant details from about: config

• browser.sessionstore.max_resumed_crashes (is set to 1)
• browser.sessionstore.resume_from_crash (is set to true)
• No 3rd party third party cleaning software
• Two extensions, tab stash and tree tabs
• There are no entries in about:crash for this event

Have been using Firefox from 2004 with 5-10 open windows which appear on bootup as they existed from the prior session. This is the first occurance of this error. Appreciate your support. Here are a few system details:

1.) 28gb ram 2.) Linux ~ LMDE 5 (Elsie) 3.) Firefox ESR 115.8 (oesr) 64 bit.

This started happening a few days ago.

I tried to drag a tab out of the main window to put it in its own window on my other monitor, but the tab just became unselectable, and if i scrolled in the tab bar, the tab icon and text would remain locked in place in the display while the other tabs moved behind it.

The main Firefox window also lost the minimize, restore, and close buttons. The only way to make the tabs work was to close Firefox and relaunch it.

I noticed this happened only after any app in the OS went full screen, be it a steam game, or another Firefox window, or a VLC window, or anything else that I did that made an app full screen in any of my monitors.

I am using Ubuntu 24.04 with KDE Plasma 5.27.12. Kernel is 6.14.0-29. Display server is Wayland.

Initially I thought this could be a problem with the snap version of Firefox, so now I've installed the deb package, but the problem remains. Firefox is the only app which presents a problem of any kind when any window goes full screen.

Here's a video showing what the problem looks like, in case my description was not clear. The ghostly tab in this video is the chess.com home page and you can see it as the third tab from the top right of the video, and it remains in that position as i scroll the other tabs, completely unselectable with the mouse.

Any idea of what could be causing this issue to appear?

Thank you!

I disabled graphics acceleration and I have the same problem. I tried several distros, it's the same thing each time, Firefox crashes and it's impossible to surf. could someone help me? I'm on opensuse thunbelweed

Dear Mozilla Support, [please forgive my poor English - FRENCH is my mother tongue]

CONTEXT - I use a Linux (Peppermint) Live DVD to surf the Web, always on the same laptop. I do NOT use any hard disk inside that laptop, just the Live DVD spinned by a DVD player. Only the RAM stores data => fresh new distro for every session - years ago, I created a Firefox account, and the Sync worked perfectly, and allowed me to back up my Bookmarks AND my Opened Tabs (they are stored in Mozzila's cloud, and after each sign in and a sync, they reappear in the left panel). Regarding the Synced Tabs, the left panel used to store all the previous Live DVD sessions (generally with the device's name: peppermint's Linux... (IIRC). - i do NOT use several devices, and do NOT wish to sync date acreoss them. I use Sync to get my Bookmarks and Opened Tabs synced across successive Firefox sessions, day after day. I worked perfectly well.

PROBLEM Since a few weeks, I noted that despite login and sync, on the left panel - Synced Tabs are now empty: no tabs synced at all => so I cannot seamlessly find back my opened tabs from one session to another (if I switch off my laptop, then later restart a new Live DVD session) - see screenshot = https://imgur.com/LO6jWLYl.png - Bookmarks are nevertheless still perfectly synced (see screenshot = https://i.imgur.com/Td0nbY2.png)

Many thanks for you help. Kind regards from Europe.

Hello. I am using Linux Mint 21.3 cinnamon and Firefox 144.0.2 When I use Google maps and the yellow small pointer (cartoon) to go on a specific street, the window come black when shifting to street view. My only extension is disabled, hardware acceleration unchecked, cache cleared and cookies cleared. I have made fresh install and nothing help. Troubleshooting mode allow street view to work fine but normal mode don't work. Google chrome work good. Chromium work good. And finally, Firefox work ok on my Linux mint LMDE 6.

Any idea where to go to solve this issue?

Thanks for your support

Hello, I'm using Firefox as my default browser for a while now (10+ years) and I'm getting frustrated with this issue when using Azure Devops. Comments don't load at all and most pages take a long time to load if they load at all. Various features also take a long time to load or don't work at all (examples include adding a reviewer, referencing a story with #, etc.). Anyone else experience this?

It works well for maybe an hour, and after a couple of days it makes no sense anymore.

Now I'm using firefox containers with a container only for Azure Devops and seems working better but ... Curious thing is that it pops up and asks for credentials periodically every 5 or 10 minutes. Well, unless the boxes are already filled up with the credentials.

Thanks,

Hi, I have a disaster situation. I backed up my profile and then I wiped my computer running Ubuntu 20.04. I replaced it with Ubuntu 24.04. Now my profile seems to not be compatible with the Firefox installation on Ubuntu 24.04.

I followed this official instructions: https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

I put my old profile in the ~/snap/firefox/common/.mozilla/firefox/ folder and I set the correct values in profiles.ini. But sadly when I start Firefox all my passwords, extensions and history are not there. I lost everything.

I'm super desperate. Please tell me I can fix this somehow. Why is the official documentation lying?

The credit card save/auto-fill option seems to have disappeared from the settings on Firefox. I previously had it set to 'off', but when there was an issue recently I found the option was gone - although the about:config was still showing credit card options. Has this option been removed from Firefox now?

Hello,

Moving from an older Ubuntu 18.04 machine where Firefox is limited to version 113 to a newer machine running Mint 22 where the current version is 134.

I know how to transfer the profiles but I could not find any information on compatibility.

Would I need to install other versions before 134 to handle any changes?

Thank you

My apologies if I am being a numpty, but I have been using Firefox for many years without issue, and recently (possibly after an update, but I cannot be certain), it has started to randomly freeze. I am running Ubuntu 22.04, and Firefox 119.0. I have demonstrated to myself that if I open a web page with links (but not always), and click on the link, I may still scroll up and down the page, but the mouse cursor never seemed to recognise the hotlink, and doesn't jump to it. The links will work on Chromium. I initially tried resetting the browser, thereby losing all my open pages, but that didn't work. That also removed all extensions ("all" two of them) and that didn't work. Firefox is now pretty much unusable. Any help to resolve this would be appreciated, as I cannot find any solutions online, and it seems I am not alone with this issue! Many thanks,

After tinkering with about:config (shouldn't have...) the background of every page that does not specify a body background color turns the color of my theme background color.

Using the firefox color pipette says its white, but it clearly isn't.

The theme i have is dark, making any page that expects the background to be white unreadable (without DevTools -> Body -> background-color: white)

I haven't been able to find the config that fixes it.

I'm trying to migrate to the newest version of Firefox on an old installation of Fedora. I've downloaded and unpacked the installation files but can't identify the installer. All I probably need is the name, as I know how to make it executable and run it once I know what file it is.
