Firefox Community Forum

Fire fox is automatically playing videos/sound or both if I click on a tab that has that or also in facebook, etc. How do I stop this? I want to be able to click play when I want to hear/see something.

Hi All,

I have tried the new free browser VPN however it does not load pages if I am using a custom DNS (Quad9) and have DNS over HTTPS enabled. Is this expected behaviour and just a limitation of the VPN?

Any advice would be much appreciated.

'bold textHow do I remove the recent browsing button from tab bar. I get shaky hand sometimes and this annoying button messes Firefox up. It is the most annoying new feature ever.

I'm using Firefox v126. I'm searching through the add-ons trying to find a few that I like and most don't work with my older version of Firefox. So I click into the version history of the add-on and find an older version of the add-on that will work with the version of Firefox I am running. Except... I click it and I get:

"The add-on downloaded from this site could not be installed because it appears to be corrupt."

say what? ok maybe a fluke, so I click on through, older version, older version, still old version. All give me the same error. Okay, maybe its just the add-on, no, its literally any older version of any add-on.

No way all those versions of add-ons are "corrupt." I can download the .xpi, rename to .zip and view the contents. Anyone run into this particular problem before and if so, how did you fix it? I'm keen to keep v126 of Firefox and would like to use the add-ons that I like to work with it.

My Dell Precision Laptop from 2019 runs a frequently updated Ubuntu 24.04. About one or two weeks ago, after one of the latest Firefox updates, i noticed that video streaming produces rectangular flickering in rapid sweeps. ( Also fast scrolling large text websites produces similar flickering, I think I would have noticed it before...) . If you detected it once, you see it always again... :-( First I fiddled around with the nvidia settings because the driver was also recently updated, without much success. Playing locally stored videos, e.g. with VLC media player, still works fine, so the nvidia driver is not the problem i think. Yesterday I installed Chromium and the video performance is fine! As good as with firefox some weeks ago! So it must be one of the latest updates, that causes the problem. Generally I like firefox more than chromium. I like the control you have, e.g. via Add ons.. So I hope that the firefox performance will increase again... Thank you for firefox! Florian Mengedoht

"Login" button does not respond to click after "Login ID" and "Password" input anymore after Apr 21 on Firefox.. Unable to access emails. https://login.netvigator.com/ Can access same website from Chrome on mini iPad or same notebook though.. How can I resolve the problem on Firefox?? Thank you.

You say, "Some essential Mozilla services are excluded from VPN routing to ensure sign-in, VPN reconnection, and screens needed to sign in for public Wi-Fi work properly. All other browsing activity in Firefox remains protected when the VPN is on."

How then am I protected in any kind of secure way?

All it would take is the Mozilla services using my public IP to lose my browsing protection. How are those connections secured to protect my identity from being exposed once the VPN is enabled and even after the VPN is enabled?

If the public IP can be discovered at sign-in, re-connections, and public Wi-Fi connections before the VPN is enabled, then that same public IP can be traced through internal logs to uncover all the VPN activity done after sign-in, re-connections, and public Wi-Fi access. So, how exactly can I trust the VPN protects my activity at all?

I'm just curious how you setup any protection prior to the VPN being enabled? I'm a former IT Network Specialist I had my CISCO CCNA certificate (Worked in school districts who wouldn't pay for additional certificates so I did all the study work and practice testing up to the CCNP certification just could never afford to take any of the exams beyond the CCNA). So, when I see these additional things like your 50 GB of free browser VPN and read how it works I get curious about the actual protections being provided. Are the people more vulnerable than they may be led to believe?

websites are being blocked when I click on links from my email account and I don't know why but I also want it stopped the websites are Stage32.com and https://course.fp-platform.online/learn/hRpTYcFi2UyZKzLm2gaOHg/theory

I have configured advance tracking protection and set all variables to true in the configuration editor except "privacy.resistFingerprinting.jsmloglevel" which is set to "warn". I still have a unique fingerprint. Other than starting over is there anything else I can do?

Symptoms: Gmail rendered on a half window, Youtube video boxes flickering, weird rendering stuff, is this my ancient GPU card? Other browsers work fine. Is it firefox, my Win11 machine, the old GPU? I don't want to migrate to another browser, but this is getting untenable!

I enabled the Firefox browser VPN as a test and then disabled it, after the Google search no longer worked.

Error says Google.com is unavailable, can't connect to servers etc.

Any ideas how to fix it ?

I am having issues using the search functions on car rental websites for National, Enterprise and Alamo car rentals. I enter in all the needed info for location and dates, but when I search, I get an error message that says try again later. See attached screenshot. I am using Firefox 150 and Windows 11. Other car rental sites work fine and I've never encountered this issue before.

bold textEVERY TIME I OPEN A NEW WINDOW IT CREATES A NEW TAB. IT CREATES A LIST OF TABS I MUST THEN CLEAR. HOW DO I CHANGE IT TO REPLACLE MY CURRENT WINDOW INSTEAD?

I imported my browser data,Import browser data - bookmarks, passwords, history, extensions, and auto fill data from another browser - mistakenly. Can this action be undone?

Thank you

I would like to use something else than the browser is use to download firefox on my xbox. the microsoft edge browser got worse and worse. is there any way that firefox would be able to provide its serivce on the xbox series s/x? im using the series x. it just has too many flaws and works way too bad to be a standard browser imo. i havent found a way to properly download firefox on xbox, only for smartphones. a xbox series x has way more power than any smartphone, even a series s is way above it as far as i know. therefore i dont feel like there shouldnt be a firefox version for those gaming consoles, which are also commonly used to browse the web.

I am a business owner and I need to log into united health care provider portal. Mozilla will not allow me to access. I'm using this link: https://secure.uhcprovider.com/ and Mozilla will not allow me to go further. This is causing work stoppage. Chat GPT says the link is secure. HELP! I need access so I can get paid.

From Chat GTP:

https://secure.uhcprovider.com/ I checked that exact URL, and here’s the key point:

👉 secure.uhcprovider.com is actually configured with HTTPS and a valid SSL certificate—so under normal conditions, your browser should show it as secure.

So if your browser is blocking it or labeling it “not secure,” the problem is almost certainly local (your device/network) rather than a new issue with UHC.

After I updated to the Version 150.0, everytime I want to check something on the mac menu bar, the whole page gets pushed down. Only the toolbar used to drop before the update. Thanks for any help in advance.
