Firefox Community Forum

I don't know if this ever worked in FF, since I've been on Chrome a while. I tried canvas.toBlob() in FF without a solution.

The behavior is the same whether the served image is jpg or webp. A Servlet delivers the image data, here in webp:

          response.setHeader("Content-Type", "image/webp");

On page, I use a canvas thus => see '// FIREFOX'

     var canvas = document.createElement( 'canvas' );
     canvas.width = width;
     canvas.height = avail_height;
     var context = canvas.getContext( '2d' );
     context.drawImage( imgsrc, 0, 0, width, avail_height);
     context.lineWidth = 150;

     // FIREFOX: canvas.toDataURL('image/jpeg')=black, png,webp,default=transparent
     img.src = canvas.toDataURL('image/jpeg');

     img.onmousedown = disableDragging; // for FF
     img.style.opacity = "1.0";
     console.log('setImg ok');

Inspecting a black jpeg:

        data:image/jpeg;base64,...

Thanks!

I use AdBlock. In my Firefox Settings I have a list of sites for which I want AdBlock turned off. They don't work and I'm still locked out. What's up with this?

The "Browser Websocket Client" addon ( https://github.com/abeade/browser-websocket-client ) was automatically disabled. The addons manager says:

> This extension is restricted for violating Mozilla’s policies and has been disabled. You can enable it, but this may be risky.

However, I cannot find any information about which policies the addon violated or when. If it was logging or modifying data, I want to know to what extent I may be compromised from using the extension. If it was for lack of maintenance, I want to know so I can make an informed decision about whether to keep using it, because the addon was still useful to me and my work as of recently.

Not sure if this is the correct topic selection but nothing offered above really fits.

I tried to sign into my Allstate.com account today and kept getting error messages.

I called their tech department and they told me that Firefox has been notified a long time ago about this issue but has done nothing about it. I was told to use my email account instead of my user ID to get into my account via Firefox, but that if I do it that way, some functions still won't work on Firefox.

I was told that my Safari browser would work, and it does.

Not sure why Firefox refuses to fix this. This is crazy. I've also had problems signing in some other companies with Firefox recently where it used to work fine. It looks like they are just not keeping up with technology. I have the latest Firefox browser for my Macbook, but as companies update their sites, Firefox is staying behind. I prefer Firefox because of things like uBlock Origin, Enhancer for YouTube, and YouTube Watchmarker which I love, but I've had to use Safari more and more because of this issue.

Exactly how does one let Firefox tech know these things. They don't provide anyway to contact them which doesn't look good.

When I used to open the small puzzle shaped icon I could see my visual book marks. I have been collecting work related images here for year. Now all I see is a request to personalize my extendtions with a ton of questions and an option to add AI. Where are my book marked images??? How do I retrieve that data?????

everytime I do an update it takes forever for the tabs to load and open....if I did the vpn will my passwords also be saved and top sites be saved as I can not do fire fox top sites so have a different top site

I have recently installed the containers extension and have been having a bit of trouble with one site (the others are fine), which seems to originate from the manner in which the site is structured. As it references new pages, they are often in a different URL. For example, you start in login.site.com, which then tries to load dashboard.site.com, but it fails authentication on dashboard.site.com because it opens in a different container. Which then tries to open the login.site.com page again, which displays the login page, but showing it tying to complete the original authentication. I have tried to add each step along the way, but without success. Is there a way to overcome this?

Firefox is using about 15-20% of my CPU, with only one tab open. Running Firefox 141.0.3 (64-bit). I changed performance settings as suggested in support page; made no apparent difference. Ran Malwarebytes and McAfee scans; nothing detected. I have used Firefox for nearly 20 years, but if I cannot resolve this then I will drop Firefox and switch to another browser.

Enable Container Tabs - does not show up under: Enable Firefox containers

   Click the menu button Fx89menuButton and select Settings.
   In the General panel, scroll down to the Tabs section.
   Make sure the box next to Enable Container Tabs is checked. 

Private browsing isn't selected

Recently transferred from Chrome. My understanding was Firefox private browsing was supposed to work similarly to chrome incognito mode; once you close the browser, all local files are deleted and cookies are cleared.

However, with Firefox it maintains my logins. If I log into an account while private browsing and the close the browser, I’ll still be logged in next time I go to the website even if it’s days later (and I have never logged into this account in a non-private browsing window!)

I never had this issue using chrome incognito, so it seems to be a Firefox problem.

Is this just not something Firefox supports? Is there any way to prevent storage of cookies and private data?

My Macbook Pro's Firefox has a convenient bookmark toolbar, my Mac Air's FireFox does not. Can I find a setting on the latter to restore my settings from the former?
