Firefox Support Forum

i used to be able to go full screen mode in firefox, for example in youtube, by clicking the full screen mode button in lower right corner. this does not work any more and not only in youtube. any stream with full screen does not work. this is Firefox only as fully screen works in Opera. clicking the title bar and choosing full screen does not help. I am on Linux mint.

I recently switched to Linux mint (cinnamon) from windows 11 and have set firefox back up but the tab bar now squishes the tabs, like chrome ,instead of scrolling, like it had on windows 11. Is this feature not available on linux? And if it is how do you set it up, because I cannot find anything about it in the settings. Many thanks!

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

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?

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!

Fred

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.

I can't stay on this site for very long at all, and do my best to write out what I need as quickly as possible then leave. I would never contribute to answering any questions other then my own because how bright it is will eventually cause me pain.

In my view, it represents an amateurish view on website design and likely has an impact of skewing the regular user base to people that don't mind it.

Sincerely,

A user who only subjects themselves to this painfully, pointlessly white website if they absolutely have to.

I'm trying to troubleshoot a connection error and cannot find anything about 'SSL_ERROR_INSUFFICIENT_SECURITY_ALERT'? What is this trying to tell me exactly? Is there documentation or a debugging switch to elaborate this error, or is it really necessary to dig into the source code to find out about this? Even mozilla search and google comes up empty.

I'm running 115.12.0esr on Linux. I have another Linux system running 115.7.0esr that has no problem connecting to the same URL.

Thanks!

I have been a long term Firefox user, but recently Firefox on Ubuntu seems to have more and more problems.

Here is the most recent one: I can't buy bus tickets on a largest provider in Lithuania (nothing happens after clicking "Pay").

https://autobusubilietai.lt/en

It worked in Chromium Browser.

Tried normal, private mode, safe mode and nothing worked.

I have Firefox 127.0.2 (64-bit) on Ubuntu 22.04. I have 0 extensions or addons installed.

Another one: I cannot select the country code from the drop down list when entering phone number in Ryanair, so basically I can't buy flight tickets from there. Chromium Browser didn't work as well, but Safari did.

There’s right-click + “Forget about this site”, but that deletes the information for the entire second-level domain (say example.org).

When in the process of moving things from *.example.org to *.example.com peu à peu, then I need to be able to individually forget say chat.example.org because it’s already moved to chat.example.com but retain all information for other *.example.org hosts.

Dear friends,

I am using Firefox Browser 127.0.2 (64-bit) on a PC.

Sometimes it happens that an input field on a page in an IFRAME cannot be clicked. The buttons work, but you can't enter anything in the text field.

Only when I press in the address bar and then in the text field, now I can enter text in the text field.

Example page https://www.fantastic-food.ch Then click on the "Feedbacks" link.

Does anyone have an idea?

Kind regards Uwe

Cannot use the hours dropdown on Calendar Widget in Mozilla, when I click on the hours, the dropdown appears for half a second and then dissapears, so I cannot use it. Works fine with Edge and Chromium. OS Ubuntu 24.04. Tried private mode and disabling add-ons - only one I have is UBlock. When inspecting the console does not show any errors.
