Hello. I have a problem with firefox lagging on high end pc, these are my specs for context: cpu - ryzen 7 9800x3d gpu - rtx 5070 ram 32 gb ddr5 6000mhz motherboard - msi b850 wifi 6e

i have a folder of bookmarks called "social media". When i want to check every website there (for example: telegram, discord, whatsapp), i start manually opening them up, so i hit the folder, click the needed icon, open new tab, repeat everything. And the moment i turn on 2 tabs like that, everything starts lagging. I don't think that my pc is the problem, because it is not even half a year old + it has good specs. Maybe there is a setting that i accidentally turned off/need to turn on to remove this problem? I love firefox, and i am using it for a while now, but now i am thinking about switching browsers because of this constant lag that happens. With all due respect, Emin.

P.S. i know that you can open all of the bookmarks right clicking the bookmark folder and then pressing "open all bookmarks", but most of the times i don't need to open all of the bookmarks, that's why i open everything as i said earlier.

For quite some time now, I am unable to sign in to my account at CanadianTire.Ca I get an error. The signon process goes to CustomerAuth.Triangle.Ca for the email and password input. When I click "Sign In" the return message is a yellow triangle followed by the word "undefined" (see attached).

All other browsers I have (Brave, Chrome and Edge) can sign in without issue.

I noticed that other users have the exact same issue. I have tried all solutions I could find. The browser is up to date as of today (150.0.2 64 bit). I tried troubleshoot mode, clearing the cache, deleting cookies, history .... On the web site I turned off ETP for CanadianTire.Ca and CustomerAuth.Triangle.Com.

I have used Firefox since it was v0.93.

H E L P ! ! !

this is still really annoying: https://support.mozilla.org/en-US/questions/1500761

why is the icon even there or why does it have to disappear and then also change the tab size ?

1) if its there to enable you to play a tab in the background, then i want the option to switch the feature on or off (because i do not want to play anything in the background, atleast not via a 24/7 target practice with a mouse)

2) if its there to give you notice that there is a 'multimedia' tab open in your browser, then i want the icon to stay there and not dissapear plus change tab size...

like what is this even ? are we back in the 50s ?

Currently when I click a link in and email, it always opens in Microsoft Edge even though my computer has Firefox as default browser. Is there another setting I'm missing?

General Default browser

Firefox is your default browser. Good choice.

Hello. I have a problem with the chat.deepseek.com website - every time I launch the browser, the language settings are reset from the system (or Russian) language set manually to English. Interestingly, this problem only occurs in Firefox, while other browsers work as expected. Additionally, the test profile created again also works properly. What I have done: 1. Reinstalled the browser, but it did not help 2. Deleted the folders responsible for Local Storage in the profile folder - didn't help 3. Cleared the cookies - helped until the first restart, then it was the same. History is enabled, and cookies are not cleared when the browser is closed. How can I solve this issue without deleting my profile? I don't want to lose my bookmarks, passwords, and website settings. Thank you in advance for your assistance.

I was getting popping in audio both in Smplayer & videos on other sites. I discovered the problem went away completely when I closed the X tab. When it was open, I noticed another glitch. I keep a small video windows to keep track of my sleep time. The elapsed time is displayed on them. Only when X was open it was throwing it off by about 3 seconds a minute. I closed it in Firefox & signed onto X on Chrome & all these problems went away. This is the only web site that has ever done anything like this. What is Firefox's problem with X?

My browser was recently updated to 150.0.2, and on the new launch page after update describing new features, it prompted me that the new free mozilla vpn was available to try. When I clicked on the link to follow the steps to set it up, it said to click the vpn icon in the toolbar, but I don't see that icon there. When I go to more tools -> customize toolbar to try to find that icon to add it back, it doesn't appear among the toolbar options. Is this something I still don't have access to because it's in a limited beta, or is there some other way I should be accessing this?

I've pretty much exhausted my simple little mind about this problem. At some point around the beginning of the year, Firefox changed the fonts on all my toolbars to some ridiculously miniscule font. I've queried Google's AI several times, tried every solution I've received, all to no avail. Is there a way to do this? I just want to enlarge the font in all the toolbars, not the web site contents, and lock it in. Thanks to whoever can help me achieve this.

после обновления в панели инструментов появилась вкладка профили и она мне даром не нужна но хуже всего что теперь файрфокс каждый раз перед запуском заставляет выбирать профиль и ни какие настройки не помогают! что только не пробовал все бесполезно -- вечно выскакиевает это окно с выбором профиля! какой [edited] мог такое придумать??? и как избавится от эт ого [edited]!!! мне нужен обычный браузер каким он был до версии 150 без [edited] вкладок и [edited] ИИ

Hi,

I shared a lot of important tabs to my laptop (using the firefox built-in share/send to other device button), upon starting it, they seemed to arrive just fine and opened on my laptop, however I accidentally clicked to "history"->"restore last session", which made this firefox window go away and all my sent tabs seem lost.

Is there any way to get them back? Any type of log?

I tried the following already: - Looking through History (they do not appear there at all) - Looking at recently closed tabs (there aren't any listed) - checking synced tabs window (did not contain the ones I sent from my phone to my laptop) - checked session recovery files ( none of my synced tabs seem to have gotten stored into that session recovery file)

So is there any other log or place I can look at? I refuse to believe that this is not saved anywhere? Or on mozilla servers at least? Can support help me?

Thanks for any ideas!

EDIT: I found this, may is something similar: https://connect.mozilla.org/t5/ideas/send-tabs-log/idi-p/15640

This issue just started today.

I was attempting to watch a video on patreon, and normally I pop out the video so it is larger. This normally has no issues.

But today when I hit the button to pop it out, Firefox crashed.

Firefox then updated, so I thought maybe it was just because it needed to update.

I attempted this two more times with the same result. 

The first like I normally do where I start the video and then click the "pop out" button. Then the second time with the video paused. The minute I click the pop out option Firefox just crashes closed either way.

When I click on option/link for "Print using the system dialog box", the print preview no longer works. Instead I see message "This app doesn't support print preview" in preview pane.

Today Firefox has suddenly started using ~20% of my CPU capacity, causing my cooling fan to run high most of the time. Since I had been running Firefox v.149.latest, I tried updating to v.150.0, but that made no difference.

It's not Firefox by itself (only Task Manager open) but whenever I open another tab with almost any website (including this one) that CPU usage spikes. What gives?!

Details: Running under Windows 10 Pro (yes, I have installed the ESU package, good until thi8s fall) on a Lenovo P1 Gen 2. Currently running Firefox inside a Sandboxie Pro v1.17.4 sandbox.

Hallo,

ich habe regelmäßig das Problem, dass Firefox quasi meinen gesamten Rechner ausser gefecht setzt indem nahezu die gesamte CPU Leistung und der Arbeitsspeicher in Beschlag genommen werden. Ich surfe in der Regel mit sehr vielen Tabs. Ab ca. 100-150 Tabs benötigt Firefox bei mir zwischenzeitlich 10 GB Arbeitsspeicher und mehr und benutzt die CPU zu 80-90% sodass der Rechner teilweise kurzzeitig nicht mehr reagiert und einfriert. Besonders, wenn ich 100 Tabs und mehr auf einmal als Lesezeichen speichere (Tabs auch nur schließen, da der CPU Lüfter schon dauerhaft auf 100% läuft), friert der Rechner danach erstmal für 3-4 Minuten ein. Ich verstehe nicht, was Firefox die ganze Zeit im Hintergrund anstellt, während z.B. 250 Tabs geöffnet sind. Tabs vorzuladen macht bei der Anzahl keinen Sinn und die Wahrscheinlichkeit, dass man richtig voraussehen könnte, welchen Tab ich als nächste wieder aufrufe und dieser dann schon vorgeladen ist, ist eher gering. Gibt es Möglichkeiten z.B.: - den zur Zeit verwendeten Arbeitsspeicher sofort zu leeren, ohne einen Tab zu verlieren oder dass Firefox geschlossen wird? - dass es dann längert dauert, wenn ich einen Tab anklicke, da dieser ja nicht mehr im Cache ist, und erst wieder in den Arbeitsspeicher geladen werden muss, ist selbstverständlich und vollkommen in Ordnung. - Kann man irgendwo einstellen, wie viele Tabs z.B. im Hintergrund aktiv sein dürfen? - Kann man den zu verwendeten Arbeitsspeicher begrenzen? - und was passiert, wenn die Grenze erreicht wird? - Kann man irgendwo an den Zeiten oder ähnlichem schrauben, wonach Tabs automatisch entladen werden? Chrome friert Tabs scheinbar automatisch ein, zu mindest ist die performance dort besser.

Es bringt ja nichts, wenn alles versuche wird im RAM vorzuhalten, damit es sofort da ist, wenn der ganze Rechner damit in die Knie gezwungen wird und am Ende das gesamte System nicht mehr zu bedienen ist. Vor einigen Jahren ist Firefox bei zu vielen Tabs oft abgestürzt, dann hat sich schon gebessert.

Es fehlt mir an Einstellungen zur Anpassung, was Firefox im Hintergrund vorhalt und was Tabs machen dürfen, wenn sie nicht aktiv bedient bzw. benutzt werden. Manuelles "entladen" kommt für mich nicht in Frage, da es zu aufwändig ist, bei extremen "Multitabbing".

Ich bin seit meiner Kindeheit begeisterter Mozilla Fan (seit Gründung von Mozilla) und verteidige und empfehle Firefox wo ich nur kann. Aber dieses Performanceproblem besteht schon sehr lange, ist zwar über die letzten Jahre besser geworden, dennoch zwingt es mich schon fast, nach einer Alternative zu suchen.

Generell fehlen viele Funktionen für Extrem-Multi-Tab-Benutzer wie z.B., dass man Tabs in der Leiste markieren oder sortieren kann. Ein großer Segen wäre eine Funktion, dass Tabs, die man bereits als Lesezeichen gespeichert hat oder doppelt geöffnete Tab, direkt zu erkennen sind, ohne dass man den Tab aufruft. Aber andere Thema. Ich benutze auch keine vertikale Tableiste, nur die horizontale klassische Leiste oben am Bildschirmrand.

Ich wäre sehr Dankbar über Tips zur Lösung des Problem mit dem Arbeitsspeicher.

Grüße

Hey there since a week when I brows with Firefox on Windows desktop the RAM uses jumped from around 60% spiked to 92-95% RAM and that changed just come a long a week ago. If change brows like Chrome different story, back down at 65. So you can also see a massive number on Firefox system running.

Question: Whats the reason for the change? What happend?

Best, Janosch
