Firefox Community Forum

Lately, one particular page keeps opening in Chinese instead of English. I've checked with friends and coworkers, and it loads in English for them without any issues. I've already gone through my language settings to make sure everything is set to English, and I don't use any VPNs while browsing. Any suggestions would be greatly appreciated.

Hello dear Mozilla Team.

My Name ist Nico and I have a Problem on my Firefox PC. When im looking Into my search History i have weird Websites Like bcclk.com in there. I have Heard that These Websites are Bad Like a Virus. I reseted my Firefox and still have them.

I Need Help. What can I do?

Thanks for your Help.

Whenever I try to open a pubg.com web page (for example https://pubg.com/en-asia/news/8727) I get a very dark outline of the page with no access to any of the links. Can you assist?

I have a lot of Firefox windows and tabs open, and I really don't want to lose my session.

I wanted to open a webpage in Firefox in fullscreen mode. But evidently there's some kind of serious flaw in Firefox that makes it incapable of opening webpages in fullscreen mode. Everyone says the only workaround is to open the webpage in kiosk mode. So I tried it.

But now I have two big problems:

1. One of my Firefox windows, with all its tabs, is stuck in kiosk mode. (Even if I close the window and then restore it with Ctrl+Shift+T, it's still in kiosk mode.)

2. All new Firefox windows I open with Ctrl+N are also stuck in kiosk mode.

I don't know what to do, and I'd really appreciate any help. Thanks!

firefox used to have good history now it's only 7 days? i need to see more than 7 days, all of it being available is ideal. what prompted this - although i've been irked by it before - is needing to know how i got to a website, what was the search and/or tab spelunking that got me there? it's really important to know this. relying solely on google search (if that'll yield part of the trail) seems contrary to firefox ethos.

Subject: OCSP Must-Staple Behavior Observations in Firefox (Including iOS Platform)

Dear Firefox Team,

We have been conducting tests involving certificates with the OCSP Must-Staple extension and would like to share several observations regarding Firefox’s behavior across different platforms:

General Compliance with Must-Staple: On most platforms, Firefox correctly enforces the Must-Staple extension. That is, if a certificate includes the Must-Staple flag and the web server fails to provide a stapled OCSP response, the connection is appropriately terminated.

Unexpected Behavior on iOS: However, we have observed that Firefox on iOS does not appear to enforce this requirement consistently. Even when the server does not provide a stapled OCSP response, the browser still establishes the TLS connection. We are unsure whether this is due to platform limitations or an implementation inconsistency.

Redundant OCSP Requests Despite Stapling: Additionally, we found that Firefox still initiates an OCSP request even when a valid stapled response has already been provided by the server. This behavior not only degrades performance but may also introduce privacy concerns, it contrary to the original privacy and efficiency goals of OCSP Stapling.

Hi,

Firefox version: 139.0.4 (64-bit) OS: Windows 11

I have been having issues where Firefox tab will just crash out for no reason it appears and it happens at random times and once the tab start to crash, and I restore it, it will crash again and again. The only way tog et out of the loop is to restart Firefox.

I have tried: Refreshing/Reset, Clearing Cache and History removing all themes, disabling extensions, disabling my anti virus. Turning off hardware acceleration didn't make any different.

I currently have 2 extensions enabled: uBlock Origin 1.64.0 and Bitwarden Password Manager 2025.5.0

In the about:Crashes I have reported them all and they seem to have the same type of reasons in the Raw data/Minidump which are: EXCEPTION_ACCESS_VIOLATION_WRITE EXCEPTION_ACCESS_VIOLATION_READ

Any help as to what to try next?

Hi, for some reason, I am severely restricted in size when uploading files to Facebook, with a maximum .jpg size of under 50k. I do not have this restriction in Microsoft edge, or on my phone, only on my laptop. I do not have an ad blocker installed that I am aware of. Appreciate any help. Cheers, Merv.

There is a preference "media.gmp-widevinecdm.visible" When it is set to true we can see the Widevine addon in Add-ons and Themes. When Firefox is close the setting reverts to false and the addon is no longer visible.

Is this expected behaviour?

We cannot get Netflix to play DRM content. We are currently getting the UI3012 error. We updated the prefererence "media.gmp-widevinecdm.force-chromium-update".

I don't have a netflix account so I can't test on my PC, but setting the above preference on my PC and visiting netflix.com seems to be enough to trigger the installation of Widevine, as I have a folder called;

F:\Users\Tanya\Profiles\ownri05i.default\gmp-widevinecdm\4.10.2891.0

On my PC.

My brother, who is the one experiencing the issue, says he does not have the gmp-widevinecdm folder in his profile folder. However, before updating the force update preference he was getting the F7701-1003 error which changed to UI3012 after setting that preference.

The problem started when I updated his PC from a very old Windows 10 21H2 patch level (2486), to the current 21H2 patch level 5854 and updated Firefox 115.9.1 to Firefox 128.11.0

Will look into OS version upgrades later in the year, but for now I'd like to get Netflix working again.

I am no longer able to send an article or something downloaded from the internet, via the email option offered, because I just get my own email sign-in box in the past and I want to be able to use this option again. Please tell me if there is a setting that's been changed. Thanks.
