The app sizes two adjacent images to the same height. Maybe there's a better approach?

This works, in that I see the original image displayed at the wrong size:

   //img.src = imgsrc.src;

This sizes the image but without the data (black square for toDataURL w/ image/jpeg) in FF, but not Chrome and Safari:

   var canvas = document.createElement( 'canvas' );
   canvas.width = width;
   canvas.height = avail_height;
   var context = canvas.getContext( '2d' );

   // Tried/failed: Fill white background for JPEG export
   //context.fillStyle = '#fff';
   //context.fillRect(0, 0, canvas.width, canvas.height);

   context.drawImage( imgsrc, 0, 0, canvas.width, canvas.height);
   context.lineWidth = 150; // ??

   img.src = canvas.toDataURL('image/jpeg', 0.92);
   img.onmousedown = disableDragging; // for FF
   img.style.opacity = "1.0"

The page is the view.html one gets to via Enter on phobrain.com.

I was asked to create a new profile in order to keep using Firefox, despite never having an account. After I clicked okay, it opened the new version of Firefox, but without all the passwords, bookmarks and history of the past few years. This is really inconvenient. I have since then made an account, but the fact that I can't find any of this data anywhere has me worried that every time I update Firefox it will wipe my account.

I want the browser's tab bar to display like the homepage, instead of disappearing after opening a webpage tab bar. I don't know if I can accurately express my meaning, but I will attach two pictures

I am using FF desktop. All of a sudden, I get no sound through my laptop speakers when trying to watch videos (on YT and FB for example). I still get sound if I use external speakers through the 3.5" jack. I still get sound through other browsers, no matter if it's through the laptop speakers or external ones. So, it is definitely an FF problem. Sound works fine on all other media files on the laptop. Refreshing FF didn't fix it. Nor did reinstalling or restarting the laptop. I tried changing the autoplay settings as suggested in the help article, but still no laptop audio via FF. How can I fix this? Thanks

Firefox crashed and I cannot recover my tabs from history. I click on restore all tabs and it does nothing. The tabs I was hoping to recover do not even appear in my history either.

See the image below, how do I prevent that black box showing up and showing anyone who uses my device my sensitive data? How is this not a common setting to be changed?

Very insecure and Horrible to have on by default. Recently switched to firefox from chrome because of security concerns but stuff like this is making me want to go back, because HOW IS THIS SAFE AND SECURE?!?!?!?

I've typed in passwords in boxes that arent really password boxes, and firefox has suggested my own password in plain sight like in the image below.

Strongly recommend firefox to not make this default and make it an accessible setting to disable because I've leaked my sensitive information to online calls because of this. This urgently needs to be addressed as a security concern. At least have a cogwheel button next to the black box to quickly disable this setting. Very very disappointed.

Hi all, I'm using Firefox 140.0.4 (64-bit) on Debian Trixie and I'm getting a weird behavior with the auto-complete functionality of the address bar.

If I type the first character the address gets auto filled (see 20250711_First-character-auto-fill-working.png attachment), then if I type the second character the auto filled result disappears (see 20250711_Second-character-auto-fill-NOT-working.png).

I've tried any search option combination, but results doesn't change. At the moment I'm using for the address bar just "Browsing history" (see 20250711_Address-bar-settings.png).

The correct behavior would be, as in the past, that new characters confirming the address would leave things as they are. Do you have any suggestion on how to restore the original behavior?

Many thanks,

Raoul

Hi. I'm still new to Firefox and don't really know the settings very well. I recently switched over to using it and realized that when I use most drop down boxes the background of the drop down menu is black, but the text is white and the selection box (when you hover over the item) is also white. Making whatever I'm hovering over very hard to see. I'm wondering if I have a strange setting turned on or not?

Settings wise I have Firefox set to dark mode, not the auto. But when I use the auto it still happens. Trying it in safe mode it still happens. Iv tried to research this a little myself. And read something about the proton setting and turning that from true to false. But this also did not work.

Is there any way to fix this? I just need the text to be a different color or the selection box (when you hover over it) to be a different color.

Attached are two screenshots of what I'm seeing

I accidentally clicked on a site that was supposed to be a game review site that I found on a Bing search. Now I get pop up ads for fake virus programs whenever I run Firefox.

I ran a scan with Mallware Bytes and Microsoft Defender and both scans came up clean.

I am including a screenshot of the popups.

Any ideas?

Thanks

I keep a lot of tabs open (~60) in any particular session - I find it's faster in this way to get back to a site.

About every six months or so, I lose *all* these tabs because of Firefox's inadequate session backup system. It only saves two or three total backups, some of which are completely out of date. But the worst scenario is when (1) some site pops up a new window; (2) I mistakenly close my main window before the new window; (3) I open this new saved window once or twice by accident, causing my 60-tab session backup to be overwritten.

Using a third-party session manager (I have tried all the well-known ones) can mitigate this problem, but doesn't really solve it because the re-opened sessions aren't quite in the same format as Firefox sessions and so lose information. In particular, I often lose each tab's icon as well as metadata for Tree Style Tab.

Could Mozilla please consider a more robust session backup system for Firefox? All it would take (I think) is to allow the user to choose the total number of backup sessions and the frequency at which a new session is added. Thank you!

I have read all your tutorials. I was unable to have an important televisit with my doctor yesterday because nothing I tried worked. I am unable to use webcam for other sites until I resolve this problem. Previously I had no problem with my webcam but recently had to get new pc with windows 11 & needs to configure my pc to address this issue. I have another appt scheduled with another doctor & need to fix this problem asap Thanks

Hi there! The New Tab page looks great with white text, but Firefox 140.0.4 thinks my wallpaper is white, so text should be dark. I can change the body class to "activity-stream darkWallpaper" using the inspector and it works fine, but how make this change permanently?

When I click on a bookmark, FF opens it in the current tab, overwriting the site I had open. I have to add a tab, then click on the bookmark to have it in a new tab. This is an annoying extra step. How to I change it? I already tried the open links in new tabs instead of windows. Makes no difference On or Off

Firefox has taken to sending pop-ups of breaking news, which I then have to clear manually (Win 10) How can I stop this.

I have looked in settings, but can't find an off switch for this "new" toy. At least the Thunderbird notifications disappear after a few seconds! These just pile up till they block the entire right hand side of my screen - and then they keep going, and block other more important notifications in the main notifications bit.

After Windows crashed, I installed a new system and logged into Firefox using my account. But all my history, passwords, bookmarks were erased. I also went to my phone and everything was gone. I didn't erase anything myself. Is there any way to restore the previous state of the account? Are there any backups on the Firefox Sync server?

I am using the Raindrop (raindrop.io) bookmark manager. It has been working fine on Firefox for years. However, with my recent update to Firefox 140, it is broken. Specifically, I can no longer use the highlighting function. It works fine on Chrome, but not on Firefox. I've seen several similar reports on Reddit's Firefox forum (r/firefox).

What to do? I don't want to have to switch to Chrome. Suggestions appreciated.

It's really strange (I'm still trying to understand my relatively new Windows 11 laptop), bookmarks have been where I'd expect them for a few days, then this morning, it's as if Firefox has done some sort of clean/re-arrangement. The bookmarks had disappeared and there wasn't my usual array of sites available along the top. Then by clicking on a few things on the right (Firefox) 'most used' re-appeared, then later the toolbar is there on the right, I'd really like it back on the left And also I'd love to know whether I might have done something unconsciously which caused this.
