Firefox allow to disable access to canvas for lowering fingerprinting, it's cool !

But as web developer : i like to ask this access before try to using it,

Something like :

1. Do you alllow canvas ? 2. Show the browser part 3. Wait for user answer 4. It's OK : download PDF done with canvass 5. It's not OK : shown an error to user.

To avoid such situation (see screencast)

• The attached image shows Firefox (on the right) not displaying Helvetica correctly. It appears jagged and not pleasant to look at. The browser on the left is Edge and all Chromium based web browsers seem to render it as it should.
• I've tried to look into (about:preferences#general) and the option that says (Allow pages to choose their own fonts, instead of your selections above) is ticked.
• I've also tried reinstalling the browser, clearing the website cache and also, removing my profile from it. None of these seemed to fix the issue.
• It's been persistent for quite some time now, however I didn't really find any articles regarding this issue.

  Any help would be greatly appreciated!

Hello, when I'm on a website that could use my microphone or camera, I am not getting the prompt to ask for permission to use them. I have tried manualy giving the website permission in CTRL-I website settings. But that did not fix it. I have tried the same websites in google chrome, and my mic works then.

I must've accidentally pressed a button last night while I was watching a YouTube video on my desktop, as now the right and bottom edges are cut off when the video is in standard mode. Refreshing hasn't fixed the issue, neither has restarting or shutting down my laptop, as it was turned off for 12+ hours and I still had the issue when using YouTube today. It's even an issue in incognito mode, but not an issue if I use a completely different browser. I can't find anything else that has been affected by whatever button I must have pushed. Laptop is a Dell G15, if that's relevant. Would love any tips to fix this.

I have tried watching videos through chrome and other browsers by searching something via duck duck go and watching that video on duck duck go, and it works on other browser so it must be specific to firefox.

Whenever I try to watch a video, in the drop down bar firefox select to mute audio for some reason. I then select 'allow audio and video' and refresh the page but the video is still muted for some reason. This also happens when I try to use other video sites. This has only started to happen recently in the past two days (and yes I am updated to the latest version of firefox).

Instacart webpage suddenly will not display/open on Firefox but can display fine on Chrome. Instacart App on mobile phone works fine, just won't open in Firefox. Any suggestions other than using Chrome? Firefox version 101.0.1 Windows 10. Was working fine until latest update installed this morning.

I noticed this first when I had to force Google to go into dark mode even though firefox was already in dark mode.

I have searched through some issue reports and have seen a lot of people mentioning that their system theme is not being detected properly. This is not that issue. I can set the firefox "Website appearance" to dark or automatic at which point the UI of firefox itself does do into dark mode so no issues there. However if I go to a website that tries to query 'prefers-color-scheme' and set its theme accordingly it always returns 'light'. This is the case even if I set the 'layout.css.prefers-color-scheme.content-override' to 0 in about:config.

I used this website to test: https://septatrix.github.io/prefers-color-scheme-test/

The issue persists when opening a website in a private window.

Let me know if I need to provide additional information.

We've noticed that in Firefox 112.0 (maybe in 111.0? haven't tested yet...) when a `fetch` request with an `Authorization` header gets a `302` (or `307`, and probably any other redirect response code) and `redirect` is set to `follow`, the second request is made _without_ an `Authorization` header, which breaks our website.

In 110.0 this isn't an issue, and no warning is logged to tell us it's about to change.

I'm guessing this is a security change - could someone point me at the discussion that led to it being made? My feeling is that if the redirect is to the same origin as the original request sending the same `Authorization` header should be secure enough.

I'm wondering what the right mitigation is; we could follow redirects manually of course, but it's a pain.

This page just gives me a blank page.........and various other 'meta' pages/sites Facebook is fine Tried in Safe Mode but just the same.

My problem is a new issue with Firefox and CenturyLink. I tried chatting with Century Link and they keep referring me to Firefox so here is the issue. In October I was able to log in to Century Link and view/download my current bill. This month when I try to view the bill all I get is a grey screen and no data. I have been forced to use Microsoft Edge which DOES allow me to view/download the bill. Also, the Chat feature on Century Link via Firefox does not work. It does work in Microsoft Edge. Something in Firefox changed in the past month and I haven't a clue what it is.

Hello, since 2 weeks I have some plugin who are not displaying in my wordpress dashboard and they are working normally on Chrome. This morning I got this message: An error occurred while connecting to WordPress REST API. It seems blocked by one of your plugins or your theme. Thanks for your help

Why are google sites (Youtube, Gmail and Search) getting disconnected when all other sites are still connected to the Net? This has been happening since November 2021.

When that happens I close the FF and then immediately open it. Now the google sites work properly.

Never had that problem with other sites.....never!

Why the hell is this happening? Is FF responsible or Google?

So what is the solution?

Since Firefox 109 and 110 also you can not login to hidive.com. It just loads a blank page(empty source) but not logged in. Firefox Developer Edition does work. 110 and 111. Tested on both linux and windows without extensions and tested with tracking prevention turned off. I reported this after 109, but I could not find the report.

I am using Firefox 108.0.2(32bit) on a Windows 7 computer. Within the last three weeks two sites Menards.com & aarp.org have become blocked by security rules: Menards by Incapsula & AARP by Imperva. All other websites I currently visit work fine as did these before. I've cleared cache and cookies and "forget these websites" in history. This solves the problem for the first page on Menards.com but any link-click and the problem returns. This also cleared the AARP website but I cannot log in to my account there nor access some of the other clickable links. I can access these websites fine on other computers on this network using Firefox. This computer will access those two sites using the portable chrome browser but not the installed Tor browser. This computer will not access these sites using a VPN or with AVG disabled. I've toggled a few DNS and HTTP settings with no effects. For a year, the only thing I noticed different from this computers and the others is that this one continues to allow Java to be updated whereas the others are unable to download its update. Could that be the problem? Why these are the only two websites that seem to be affected is the baffling part. Menards has thanked me but has not gotten back and AARP wants me to reinstall my operating system. Thanks for any help you may suggest.

One particular website that I login to frequently in Firefox suddenly stopped opening the login screen when I click "Login." It opens in Safari and Tor browsers, but not Firefox. How do I get the login screen to appear? I have disabled enabled Pop Up Windows for this site, but it still won't load the login screen. It works in Troubleshoot mode. What does that mean and how do I get it to load the login screen in normal mode?

When I try to go the the site https://tvlistings.zap2it.com/ it show top part of page while it tries to retrieve TV listings, but then the whole page goes blank. It still goes blank when in troubleshooting mode.

Works with Microsoft Edge browser. Any ideas?

When playing any youtube video in full screen, all I get is a black screen. Issue does not appear in private mode, firefox developer build or chrome. Other sites ex. go pro media plays videos in full screen without any problems

Lately for the last 3ish days my YouTube connection speed on Firefox and only Firefox has been terribly slow. So slow that it can't even watch normal HD content. But not always, sometimes it does work at normal internet speeds which is so weird. I have around 500 Mbps download speed internet so I know it's not the issue. The picture with the slow download speed is on Firefox and the fast/normal download speed is on Chrome. Sometimes in a private window Firefox runs at normal speed but not always, I don't think it's an extension issue.

I've been watching and following along with a Unreal Engine 4 Course on Youtube for some time now (mentioning in case the resource usage has something to do with it), and in the past couple days I've noticed a pretty serious and annoying bug. When I pause the video, tab (Cmd + Tab on MacOS) into Unreal Engine, do some things, then tab back and resume the video, it will play for one frame and then stop and buffer, but the audio will continue playing. The only way to get the video to resume is to skip forward/backward in the video (either with the arrow keys or the progress bar). I've also tried Troubleshooting/Safe mode and the issue still persits.

I'm trying to use Microsoft Teams in Firefox because the native app for Linux is abandoned and crashes, and at first sight the app is blocking Firefox on purpose. Buttons to make calls are disabled, stating that audio and video are not supported in my browser, but everything works normally if join to existing calls using e.g. links.

Is it possible to trick Teams to think I'm using Chrome? I found the "User-Agent Switcher and Manager" add-on, but I can't figure out how to possibly use it.
