Diễn đàn hỗ trợ Firefox

I have a two monitor setup. Since I installed the new AMD driver (26.1.1), sometimes when I play a game on my main monitor, and watch stream on Twitch in Firefox on my second monitor, it can cause the PC to freeze completely. I hear the sound, but the image is stuck.

I tried to disable the hardware acceleration in Firefox, and it seemed like a good solution. But because of that (which is its function), sites became laggy.

Is this a Firefox, or an AMD issue? Or Windows (I'm on Windows 11 25H2)? I will try to install an older AMD driver, but honestly streams had became laggy before the driver update for me.

Firefox is my default browser, but often shows my location wrong in my home location. Google chrome and maps shows it correctly. Please tell me where firefox thinks I am and how I might correct it.

bold textI have an Apple comp. I have been using Firefox with the Apple for over 10 years, suddenly Protonmail isn't working in Firefox........it works in Google and the Safari Browser on this Apple....... but the latest version of Firefox isn't working.....also unable to Copy & Paste on Firefox I think it might have something to do with the Bridge for Apple computer/Safari. I don't Know.

Ho molti problemi da circa tre giorni. Quando apro alcune pagine, a volte si verificano problemi di rendering e la parte grafica del sito non viene caricata correttamente. La pagina appare completamente grigia, ma in realtà è caricata — se clicco a caso sullo schermo vedo che i link reagiscono, quindi la pagina risponde anche se non viene disegnata correttamente.

Su X e Twitch questo succede spesso. Con Twitch, mentre sto guardando una live, se parte una pubblicità oppure cambio stream, lo schermo diventa completamente nero. Quando succede, viene coinvolto tutto il browser — anche se ho più schede aperte sui miei due monitor. Anche i pulsanti della finestra in alto (minimizza, massimizza, chiudi) cambiano stile e sembrano quelli del vecchio Internet Explorer.

Se avvio Firefox in modalità risoluzione dei problemi, X si apre correttamente, ma Twitch continua ad avere lo stesso problema di schermo nero durante gli stream.

Ecco cosa ho già provato:

cancellare cookie e cache

disabilitare tutte le estensioni

disattivare e riattivare l’accelerazione hardware

usare la modalità risoluzione dei problemi

provare altre soluzioni trovate online

Nessuna di queste soluzioni ha funzionato finora.

When i logged into a privacy session on a website the account did not automatically log out when i closed the session. I checked again by purposefully ensuring i closed all privacy windows but when i went back to the sight i was still logged in. I had to specifically log out the account.

Has something changed with the setting? This was one of the features that i liked. I don't want to find a new browser because what i expect is no longer happening.

I've tuned in to Firefox this morning to find that I'm kind of shut out, no access to my usual apps, and required to enact some difficult backing up etc. When I explore, it seems to relate to Windows 10 losing its backup from Microsoft. But I'm running Windows 11, not 10. What's going on? Is this legitimate? If so, why is it complicated and why wasn't it forewarned (by Firefox)?

I have been having trouble with my Windows 11 laptop. In my efforts to resolve these issues I noticed that I now have two installs of Firefox in my Control Panel. Both installed during my time of dealing with my Windows issue. Five days apart Feb 5 and 10, 2026. Both show the same version number 147.0.3, and same size 322MB. I have used FF for many years so these seem to have been installed sometime during my efforts to repair Windows. My FF was never a part of the Windows issue AFAIK.

Anyway I have FF working as I like with my Session Manager and various AddOns and personal settings, so I do not want to have to start over with FF. So how do I choose which instance of FF to uninstall in Control Panel?

My issue with Windows was my Outlook would not connect to the server. I assume Microsoft Exchange server, my internet connectivity was fine. And FF was fne as well. I eventually was able to repair my M365 connectivity. Major PITA from out of nowhere.

I've been searching for three days now for a solution that will work to restore my profile from a crashed windows-7 machine to my new windows-11. Nothing listed in any forum or help desk works as described. I used to be able to just rename the folder to the exact file name on the new PC, but windows 11 won't let me do anything. It always needs admin permissions and even after I activated the admin account and assigned a password, I still cannot copy to the folder or rename the folder. Every attempt to do this on W-11 fails. It shouldn't be that hard and I'm tired of wasting days playing with this. I have important bookmarks, passwords etc. I want restored, and I need help. Nobody wants to pick up a phone anymore to assist!

I have never used "sync" because I have multiple PCs and each used for different applications and yes some go back to W-7, the operating system that actually worked well. Each PC has Firefox and a distinct bookmark file.

I went to "about:profiles" and created a new profile thinking I could copy to the new folder, but when i switched profiles I couldn't get back to the original default! HELP!

Many thanks,

Hello, everyone,

Tried to download Firefox onto my android mobile, but it kept saying I have to get the app from google.

Due to my ‘thing’ about internet security, I will not use google at any price!

Can you direct me to where I might get the app elsewhere, please?

Thanx very much,
