In Firefox, When H264 frames are decoded and rendered within a single tab, the output reaches up to 180 fps, performing well and meeting expectations. When decoding and rendering occur on two separate tabs on parallel, performance significantly drops, impacting both processes. However, it performs smoothly when running on a single tab.

In comparison to the Brave browser, H264 decoding and rendering are noticeably slower in Firefox. Firefox manages only around 180 fps, while Brave and other Chromium-based browsers can achieve approximately 1000 fps on a single tab and around 800 fps when multiple tabs are open.

Tell me how to reset a new password, I simply forgot my old one. I have been using Mozilla Foxfire for many, many years and now it's a problem because a password prompt keeps on reusing my password that is incorrect.

Bonjour, je ne peux plus me connecter à ma boite mail hotmail.com depuis la version 144.0.2 (64bits) de Firefox Je suis avec Windows 11 famille 64 bits - 24H2 et 25H2 (j'ai essayé avec les 2 versions) avec un compte local. Je choisis de me connecter avec un mot de passe et après avoir validé le mot de passe, j'arrive sur une page qui me dit d'utiliser un autre appareil ou une autre méthode de connexion. Je joins les fenêtres de connexion étape par étape Avec Google Chrome (que je ne veux pas utiliser), je me connecte sans problème à ma boite mail avec les même étapes décrites ci-dessus. Pouvez-vous m'apporter une solution ? Merci, Marc T.

Hello, I reinstalled Firefox and am unable to recover my bookmarks and other data. Before the re-installation, I manually backed up my data, but when I try to restore from the backup, it does not work. All my bookmarks and previous data are still missing. How can I fix this and recover my information?

I'm running Firefox 144.0.2 (64-bit) on a Mac using Sequoia 15.4.1 OS.

At the most recent Firefox update, I added VPN.

Since then, I've had a problem with Firefox hanging. Not immediately but after varying amounts of time, 20-60 minutes. I get an "Out of Application Memory" pop-up but the usage for both Firefox and other elements are well within normal range, not high. It's completely frozen and the only way out is to do a Force Quit.

There are times when doing a shut down I notice that VPN has somehow been turned Off and once I saw a message of Background Service Error attached to it.

Having to constantly re-start Firefox is a major pain. Oh-- I did turn off the background AI thing under Tabs. I hate AI and try to turn it off everywhere I find it. A resource suck and bad for the planet.

Any help appreciated.

I installed Firefox yesterday, and everything was fine for a day. Today, when I play a YouTube video, the entire page freezes - I can't pause it, select text, or do anything. The page starts responding after about 10 seconds from last interaction.

Compared to Chrome, I can play 20 YouTube videos at once and everything works fine.

The problem only occurs on YouTube. Sites like CDA and Jellyfin work fine.

Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

I am a pensioner in te UK. Due to restricted mobility I spend a lot of time using Firefox to access many web sites. This normally works perfectly. Today I tried to access the web site of national chain store specialising in outdoor clothing and equipment because I need a new showerproof jacket. I have never used that site before, yet Firefox reported Error 403 : Forbidden. Have you people never been told tat error messages are supposed to be useful? What is Forbidden. Why when it has not happemed before?

The web site is https://www.millets.co.uk/

I have a web site so I have other browsers just for checking for layout problems.

I tried Chromium, same error but the message said You are not authorised to access this site. Presumably that is what your incompetent message should have said. But why should a pensioner trying to buy something from a chain store ever need any sort of authorisation?

I tried Opera. Connected me no problem!

I tried Edge. Connected me no problem.

Clearly somebody somewhere is an incompetent idiot, but it isn't me. So who is it? If it is yourselves then please do something to fix this.

I've blocked access to nearby devices without knowing that this would affect my local network websites. Now the option to change this on the settings simply does not appear for me. What can I do?

Firefox 144.0 on a W11 PC with all updates.

Firefox is running multiple (10-13) windows with 5-10 tabs each. Even if all Firefox windows are minimised and not being used, memory usage goes up all the time. It is currently, according to Task Manager, using over 5 GB of 32 GB of available memory. CPU is sitting at ~4%. Individual tabs, like Youtube watching CNN suddenly freeze and are no langer accessible and can't be unfrozen by anything I have tried. Even the mouse pointer is not displayed inside this tab I need to restart the entire PC several times a day only to have Firefox usable. I have turned off efficiency mode, but this did not change anything. I'll include a system snapshot with msinfo

Any ideas?

I have no idea how my bookmarks disappeared, but I cannot locate any of them. How can I get, at least, my bookmarks from one month ago. Have an upgraded computer, new hard drives, etc. I've searched my computer, cannot find any bookmarks. Is there hope? Win `11

This has now happened three times. I implemented the new profiles feature a few days ago, and have three profiles. The issue is that my main profile, every time I reboot my computer/open firefox forgets all my logins. I use a password manager and don't store them in firefox ; this has never been an issue before. It is happening on the same profile each time. My bookmarks/extensions stay the same. This is happening on sites even when I have clicked 'keep me logged in'. There is no site/login that is unaffected - it seems to reset my login status I want to reiterate this is all happening on the same profile - this is not an issue of logins not carrying between different profiles The only other setting I changed is auto-storing passwords on firefox [It had saved my master password accidentally, so.] But there were very few passwords actually stored there, and those sites worked before. I am on Win 11 and have had no issues previously

After the update yesterday, all of the pinned icons/links on my home page have been rearranged or replaced with others. I restarted the computer and also closed the browser and opened it. Still messed up, I have several that are the same link and some that are missing.

Any way to get them back in order other than trying to figure out what is not there and resetting it all up again.

Thank you
