I have just bought a new computer running the latest version of Win 11pro and the latest version of Firefox is installed. When I click on a mailto link it will not open, I have looked on the internet and as usual the instructions to do this and the you will see this, bear no resemblance to the reality of what I see on the screen and statements such as alter this but it does not say how. This is extremely annoying to this 80 year old non computer literate person especially when the mailto link works on my old computer running Win7 pro with the same email and internet programs installed. I have Edge, Opera and Firefox as internet browsers and use Thunderbird as my email program. Can anybody explain ALL the steps to be taken in plain English to cure this problem please?

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

Guten Tag zusammen,

ich verwende Firefox 143.04. unter Windows und sortiere Lesezeichen in der Lesezeichen-Symbolleiste als Baumstruktur mit 1-2 Ebenen. Beim Anlegen eines neuen Lesezeichens aus einer geöffneten Seite via [Strg+D] wird es automatisch angelegt und in der Lesezeichenleiste gespeichert. Bis hier ist alles soweit okay, auch wenn ich mir hier einen kurzen Dialog gewünscht hätte.

Wenn dieses neue Lesezeichen per Maus (Drag and Drop) in die Ordnerstruktur eingefügt werden soll, klappt sich der Ordner im Baum auf, sobald man mit dem angefassten Lesezeichen in die Nähe kommt. Gut.

Aber: Wenn mit diesem "am Haken hängenden" Lesezeichen in der Ordnerstruktur nach rechts in die nächste Ebene navigiert wird (Ordner klappen nach rechts auf und zeigen die bereits darin befindlichen Lesezeichen), dann schließt sich diese Ansicht und man muss mit dem Lesezeichen am Haken nochmal von vorne / oben anfangen.

Das ist ultra nervig und die Sensibilität des Programms war früher nicht so filigran eingestellt.

Es gibt sicher auch einen workaround (Lesezeichen-Verwaltung separat öffnen), aber das ändert nichts an dem veränderten Verhalten und ich umständlich. Haben Sie evt. ähnliche Erfahrungen oder Berichte anderer Benutzer? Anbei im Screenshot dargestellt der Weg.

Idee / Wunsch: Können Sie die Empfindlichkeit beim Ziehen von Lesezeichen etwas "entschärfen" oder eine simplere Eingabemöglichkeit implementieren (z.B. jede Ebene durch eine Mausgeste fixieren, sodass die nicht "unter der Nase zugeht")?

Besten Dank vorab.

Für Fragen bin ich gerne offen. Beste 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 ?

Good morning,

I have been experiencing many issue in reopening closed tabs from the history menu after closing firefox. I can click it, but nothing happens. It ends up with me reopening sometimes 30+ tabs manually, which so inconvenient.

Any lead?

Thanks in advance

Is there a way to reset the Most Visited list? It's not accurate, since it has X and twitter on the list. I stopped using that site over a year ago. If I can't edit the list, is there a way to just get rid of Most Visited?

Hello,

Today my Google start up page turned Black. All other sites are normal colors. I tried basically all that I could to keep the background to system settings, no themes and no extensions added except for Image extensions (that I have no issues with). I have Firefox Version 144.0 (64-bit) On a Mac Mini OS 10.15.7

Should I do a Firefox Reset? Please help me with this issue.

Thank you, Phil Khoury

After the update on the 14th, dark mode has gained weird stylistic choices that I cannot find a way to alter: namely, when closing a new tab, a white box with black font appears -as opposed to the previous darker toned grey/purple with white font. However as of writing this post, I notice that dark mode is not working on this webpage. Seeing as I have an extension enabled in addition to the basic dark mode selection in Firefox settings, I can only imagine that something was broken in the update. Please advise, the change is jarring.

Being able to tell anyone what's going on is almost impossible. I am thinking of deleting Firefox despite having been using it for years, a loyal customer who subscribes to your VPN. When I log in my pinned tabs do not open the web sites, I'm told I've got connection issues, I've removed the sites from tracking protection, X tells me that is an issue since it only started after the update before todays update. What is the point of pinned tabs if they don't open? If I can't resolve this issue I will use Chrome, All of my pinned sites open there I just have to get used to using another browser, I don't like Chrome very much but I'm pulling my hair out getting no joy from Firefox. There has to be a better way of contacting Firefox than spend ages online as though it's top secret! I'm using windows 11 24H2

just recently firefox has been adding pop-up summaries to each address bar open tab .... the summary is a tiny 5 or 6 word pop-up describing what that website is supposed to be doing and the pop-up appears instantly whenever the cursor contacts that tab..........how can i turn that unwanted pop-up feature OFF

I had to replace my hard drive recently, and with it my Firefox install. I managed to transfer everything over to the new install, except for the URLs in Reading List. The extension itself made it over; just not any of the URLs I stored in it.

In theory, I know that I can scrounge through the Firefox install on my old hard drive and grab the necessary files, but I have no idea how I'd go about doing that. I can't rely on folder names, since those are based on extension IDs that are generated when I install the extension, and the files themselves are too opaque to glean anything useful from (Notepad++ didn't turn anything up, so I'm assuming the extension data's compressed).

Other than that, I've tried:

• Running this tool to see if there was anything I could use. There wasn't.
• Trying Load Temporary Add-ons to identify the Add-on I wanted. I accidentally erased my feeds on RSS Feed Reader doing this, so there's another extension whose data I need to restore. (It was fine before I tried Load Temporary Add-ons.)

For example, this code in userChrome.css will work for showing a custom favicon on the bookmarks toolbar:

.bookmark-item[label="Bookmark"] image {

   width:0!important;
   height:0!important;
   padding: 0 0 16px 16px !important;
   background:url(custom-icon.png)!important; 
   background-size: 16px !important;

}

However, after a recent update, if the bookmark is located inside a folder, the custom favicon will not be displayed and it will revert to the websites favicon.

See the attached image example of a bookmark on the toolbar vs. inside a folder.

ブラウザゲームサイトUnityroomなどでゲームを遊んでいると、Cookieの容量が10ギガバイトを超えることがよくあります。 どうやら10ギガバイト以上のcookieをFirefoxでは保存できないようです。 FirefoxでのCookieの容量を10ギガバイト以上にしたり、ページごとに個別に管理できるようにしてほしいです。

For the past few weeks, I have been intermittently but stubbornly getting the beachball of death when I open Firefox, coupled with Force Quit. Sometimes I force quit and then restart and it's fine. Sometimes I force quiet repeatedly and it continues not to open. Sometimes I restart my laptop and that fixes it, but sometimes not.

I do have a lot of tabs open, but i have always had a lot of tabs open. This thing is new.

What could have changed? What do I need to do, fix, trash, or curse?

(In simple language, like for your unsavvy grandma please?)
