Hello,

I deployed central management of firefox yesterday and I am suffering firefox hangs on startup (prior to opening any window) after configuration change from pref to localPref. When I kill firefox and run again it usually start normally. Usually one kill is sufficient, but I observed also two subsequent kills are necessary.

I created these files:

/usr/lib64/firefox/defaults/pref/autoconfig.js:

pref("general.config.filename", "firefox.cfg"); pref("general.config.obscure_value", 0);

/usr/lib64/firefox/firefox.cfg:

// This comment is mandatory lockPref("autoadmin.global_config_url","http://www/firefox/firefox.cfg"); lockPref("autoadmin.append_emailaddr",false);

and in the firefox.cfg on a website I have for example: lockPref("network.proxy.type", 4);

when I change the lockPref to pref in this file, everything works normally, but when I change it back to lockPref I get a firefox hang on startup. What am I doing wrong?

Thanks

Marek

Prior to ~1 week ago, my process of using Firefox was as follows:

• Open a new tab, search for something, click through a few links

If I couldn't find anything relevant in the first page of results, I'd navigate back to the Firefox Home Page and try another search. I hate going past the first page of results!

However, as of ~1 week ago, I can no longer navigate to the Firefox Home Page - why is this?

I've been using Firefox for a while and there is one file storage site that is always an issue for me. Downloads work but frequently, it stops near the end of the transfer and shows "failed" in the Library window.

Every time, I can click "resume" and it works but it's extremely annoying. If I don't watch the download carefully, I might miss the "failed" message and then the download link times out. There should be a setting to automatically retry a certain number of times.

I've tried multiple add-ons and none of them work.

Hello every professional engineer

I knew how to convert the Firefox file sessionstore.jsonlz4 to .json file by using this website https://www.jeffersonscher.com/ffu/scrounger.html

and after editing the resulting .json file

How can I convert it back to .jsonlz4 file to return it to my Firefox profile as it was?

For a long time I've used Firefox on Linux with multiple instances each with their own profile folder. Today when I try to run these instances with separate profile folders I get the following error:

> Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile.

Profiles are created like this:

firefox --new-instance --createprofile "PROFILENAME ~/.firefox-PROFILENAME"

They are run like this:

firefox --new-instance --profile "~/.firefox-PROFILENAME"

It seems something has broken with the instance isolation as this is now throwing an error. Additionally I run "createprofile" it doesn't seem to actually create the folder.

Just for info this site works fine on other browsers on same machine, and on other machines. It is a Firefox issue.

Running version 127.0.1 on Linux.

Hi! From some time now i have problem with GUI elements overlapping each other. It started with the window control buttons (that part, where you can close the window). Esthetics aside, it was not that big deal, so I just ignored it, but some time ago similar overlap appeared on address bar - so now I don't see what I'm writing. This is a big deal, now I can't really tell if I made a typo, I'm not able to correct it or I can't see if what I'm writing is mixed with original url, stuff like that.

I'm on Manjaro Linux and Firefox version is 127.0 (64 bits) I've tried to reinstall Firefox with different sources, like Flatpak for example, but the issues persists. Has anyone an idea how to fix this?

In recent Firefox versions, long container names are trimmed to around fifteen letters. Is there a way to disable this feature?

Since containers are named by the same user as the browser, people who want shorter names will name shorter ones by themselves. I wonder who wants this feature.

Version: 127.0.2

Hi,

When I seek in videos, for example on youtube, it almost always hangs the entire machine. The same issue happens randomly as videos run, eg after about 5-7 minutes.

I'm struggling to get more information on what is happening (eg logs) because the whole system hangs.

Here are some things I have discovered:

1. I can reproduce in a fresh profile 2. I can reproduce with the flatpak version 3. I can't reproduce in the Brave browser 4. I can't reproduce the problem on Windows, only on this Linux machine

I'm running on Linux (debian bookworm). I'm using wayland. I have an intel i915 GPU (Alder Lake).

The problem started recently (last few days), but I'm not able to nail down exactly what changed.

What I really want is any way to get more information about what is happening - logs or debug output or whatever. Then I can work out if the bug is in Firefox, or something else on my system (eg intel graphics drivers)

Thanks, Cal

I have four browsers on my Linux box: Chrome, Chromium, Thorium, and Firefox.

Firefox is painfully slow using Google Earth, all the others are fast with Google Earth.

This is fairly recent behavior (last month or so).

As far as I can tell, FF is configured to allow Web Assembly (WASM) to be used for rendering images, etc. Since Google Earth is written in WASM, I don't have a clue why it is so horribly slow.

scrolling/sliding the image around on the screen is slow and jumpy. Displaying images attached to a waypoint is extremely slow: It takes 5-10 seconds to switch from one image to the next.

Any suggestions? Thanks in advance!

I am using Linux Mint with Firefox 127.0.2 (64-Bit)

In Preferences Applications, setting

 CSV-Dokument      to    open with firefox

opens edless new firefox Tabs - so I had to kill firefox. (setting CSV-Dokument to open with OpenOffice works fine. But this is not what I want.)

In Preferences Applications, I found further CSV types: application/csv-Typ CSV Document (application/text) CSV Document (octet/stream) CSV Document (application/x-download) Which applications should I use for them ?

I found the file "mimeTypes.rdf". However, I am not familiar with the syntax.

Hello My friend is visually impared and is having great difficulty seeing to read emails. Is there any way to use Thunderbird to get the emails and then read them with text to speech to audio. Or can anyone think of another way. I will have to be simple too. Thanks.

Installed 127.0 (20240606181944) from http://download.opensuse.org/repositories/mozilla/openSUSE_Leap_15.5/ and since then I've been unable to:

• Close a window by closing the last tab (the last tab X does nothing)
• The toolbar Account icon has nothing under it, have to go via Settings to manually sync and manage account

Hello and good day.

I am a little lazy and i want to open firefox(one window) on my two monitors, i can do this by open firefox then open another tab, then drag to the other monitor, but i want to know if is possible to add a command on the shortcut and do this in one go.

Note: i am using linux mint 20+.

Thanks.

I'm using openSUSE Tumbleweed and KDE Plasma. Ever since I updated to Plasma 6.1, Firefox crashes constantly when using Wayland. I'm not having this problem if I'm using X11. Crash reports are sent after every crash so I'm sure someone can reference these. When starting Firefox from a console, I got this message after a crash: "[GFX1-]: Wayland protocol error: wp_linux_drm_syncobj_surface_v1#67: error 5: explicit sync is used, but no release point is set"

Will this get fixed with the next Firefox update? Currently using 127.0.

One of the typical configuration in linux is to turn off the user namespaces and/or network namespaces. This is because most of the exploits in linux have been related to namespaces vulnerabilities.

If there is a Firefox ver 127.0.2, running on Linux in which the user namespace is turned off then the following is observed in the Troubleshooting information, i.e. about:support Seccomp-BPF (System Call Filtering) true Seccomp Thread Synchronisation true User Namespaces for privileged processes true User Namespaces false Content Process Sandboxing true Media Plugin Sandboxing true

So how come with the username turned off, the content process and media plugin is still sandboxed? Also is having user namespace turned off, as given above, a security risk?

However if the network namespace is turned off, i.e. max_net_namespaces is set to zero, then it renders the browser unusable. Nothing works. Why is that?

Is there some documentation somewhere where these namespaces and their impact is explained in detail?
