Firefox-mienskipsfoarum

Tor browser 14.5.8 (based on Mozilla Firefox 128.14.0esr) LibreWolf 143.0.3-1 Each uses 100% of a CPU thread on Linux Debian 13 (Trixie) with KDE, while internet is not accessible for hours. I have tried to open new empty tab and close single website tab in Tor browser, but that did not decrease the load. Firefox 140.3.1esr also uses around 100% when i count up all its CPU threads load.

Can anyone reproduce this? Maybe the browser needs to run for some time so the issue is reproducible. If you have idea what to try (i will not use different Firefox version), let me know exact steps.

Hallo, ich habe nun schon mehrfach versucht meine Sprache im Settings umzustellen. Habe mich genau an die Anleitung gehalten. Aber ich bekomme einfach nicht die Sprache umgestellt. Ich will es auf Deutsch umstellen aber es bleibt alles beim englisch. Ich habe Cache schon gelöscht, habe meinen VPN ausgeschaltet und mehrfach den PC hochgefahren. Was läuft da bei mir falsch. Da ich kein englisch kann ist es etwas schwierig hier alles dann zu verstehen. Ich benutze Linux Ubuntu. Danke für die Hilfe.

Viele Grüße

Yesterday I switched on my PC, opened Firefox and the home page was black. See the attached screenshot. This is not caused by some accidental switching on of the dark mode. Dark mode is clearly off. Neither can I adjust settings to make the Google home page revert to its customary light grey shade.

This isn't a big deal, I know. And it has happened before and in a short period gone away by itself. Maybe it is to do with a glitch in the latest Firefox version. But it has an unpleasant appearance and discourages surfing.

My Chrome Google home page doesn't have this issue.

Can anyone advise on how to fix this unwanted black screen problem ?

So my question is Firefox is on my Cent OS 10 machine and it only shows the close button on the upper right corner, I would like to know two things, 1. How to add the Minimize, Fullscreen buttons to just the close button on the upper right corner. 2. How to get my menu bar back - the home button and all of the other goodies that normally show on the left of the browser just above the Forward, back and refresh buttons?

Thanks in advance for the help.

Dear Community,

the userChrome.css I used to use to disable the search bar expansion on focus no longer works (http://userchrome.wesleybranton.com/megabar). I disabled all urlbar.search options in about:config. But Firefox still gives me suggestions when I start typing about (as in about:config).

toolkit.legacyUserProfileCustomizations.stylesheets is set to true. The userChrome.css is inside the chrome folder inside the profile directory. I'm on 140.3.1esr (64-bit).

How do I disable this for good?

Thanks in advance!

In version 143 there is no rollup window option that allows a linux system to roll the window up out of the way. The icon is a caret located in the top right corner of the window.

Fedora froze and I had to reset my PC. Firefox hat quite a number of tabs open wich are still visible in history Recently closed tabs. When I click there on Reopen all tabs nothing happens.

How do I open all recently closed tabs?

First, why does the "recently closed tabs" doesn't work if you close an entire firefox window?

second, why isn't there a place to search through your tab groups?

I just accidentally closed a firefox window with a lot of tabs, including unnamed tab groups.

This is a pain for all browsers, but firefox took it a step further.

There is a "recently closed tab" page which is really convenient, until you need it most when you accidentally close multiple ones. On top of that, I lost multiple unnamed group tabs.

Am I missing something, or is the experience still subpar? I've been a power user of firefox for years now, and I get why I get clowned by chrome users ngl.

Have a problem getting page data? Had a campus directory page that before allowed wget2 to download pages fine for over 10 years. Now that modified pages, and get nothing? Can open the new page https://employeessb-prod.ec.guamcc.edu/EmployeeSelfService/ssb/campusDirectory#/lastName But trying to manually save page results in a 1.3M file, while using print to PDF gives a 50K file? Seems it is some kind of dynamic page, so the Save as gives a ton of garbage Java code, versus saving the final web page. Printing to PDF seems to take the final form and print the correct information.

Currently takes a 2 1/2 minutes to go to the first page, Ctrl-P, and print to PDF File. Then have to use Next option to go to pages 2-6, and manual print each one, changing the save file name each time. Makes like 6 50K files. Use pdftotext to change to text, and then combine into one file to extract data.

What took 6 seconds with wget2 to download, now takes 2 1/2 minutes??

A long time ago I was able to set the max number of rows for shortcuts on the Firefox home page to 5. Sometime fairly recently it has changed to 4. I don't know why nor can I remember which line in about;config I used to change it. I think the line was "browser.newtabpage.activity-stream.topSitesRows" but when I try to change it, it does nothing. At the time I first changed it, the max it would change to was 5. The max now appears to be 4 if I did it correctly. Your help would be appreciated.

Hi,

Every time I restart my Firefox browsers they will sign me out of my Mozilla account. I can see the email address associated with my account and 'Account disconnected'. I have to go through the process again every time I use it. I am using default privacy & security settings.

I am using :

140.3.1esr (64-bit) on Debian Trixie 143.0.4 (aarch64) on MacOS Tahoe 26.0.1 143.0.1 (64-bit) on OpenSuse Tumbleweed 20250929

Can you please help me resolve this?

Can the notification for upgrading be controlled on ver 143 on linux. It keeps appearing and as a user I should be able to silience or have it notify me at a period I prefer instead of interrupting browsing.

Using version 143 PIP does not work on different workspaces. If I open PIP the PIP only remains on the desktop that FF is on and the PIP disappears on othe workspaces.

On my linux system, I have two users. If I log in as user A and use FF and leave a bunch of tabs open, I can view those tabs again later if I restart my computer and log in as user A, so FF remembers its history.

No Problem Scenario Logged in as A - open FF - open a bunch of tabs - CLOSE FF log out of A log in as B - do stuff log out of B log in as A - open FF; all the tabs are there

Problem Scenario Logged in as A - open FF - open a bunch of tabs - leave FF open (don't close FF before...) log out of A log in as B - do stuff log out of B log in as A - open FF; all the tabs are GONE

If I run into the Problem Scenario, I can sometimes use these steps to get the history/tabs back. https://support.mozilla.org/en-US/kb/how-restore-browsing-session-backup

Whether the steps work or not, the Problem Scenario is annoying. I don't know what causes this. My desktop manager is KDE.

When trying to access many popular websites with Firefox on my Fedora 43 installation, I am greeted with a security warning page with the SEC_ERROR_UNKNOWN_ISSUER error. For most of these websites I can simply accept and continue, but HSTS-only sites will not permit this.

Affected websites include but are not limited to (based on exceptions in the certificates section of Firefox settings):

• github.io (many subdomains)
• purdue.edu (many subdomains)
• iu.edu
• ebay.com
• cbsnews.com
• iwm.org.uk
• home.cern
• celestrak.org

Any help in resolving this is appreciated.

When I do "save as " action for an image in the browser it opens dialogue window to save selected image. Unfortunately it displays files and folders in some random order, rather than my preferred order (sorted alphabetically by name, followed by sorting by type).

I can see no rhyme or reason to the way Firefox lists files and folders in the dialogue window, so every time I am saving an image I have to sort things by name and type before I can find what I want.

This is not permanent so I have to repeat this action every time I save an image.

How do I, please set application preferences? to make this setting permanent?
