I've worked with Firefox for several years, and had it opening maximized. I recently manually resized the Firefox window to facilitate some work in which I needed some other windows visible. However, now I can't get Firefox to open maximized. Instead, it opens a window going from the left edge of my screen (see the first image below) about a third of the width of the monitor, and it is showing the double box icon in the upper right corner indicating that the computer "thinks" it is in full screen. If I click that double box, the window immediately shifts to the right edge of the screen, occupying a space about a third of the monitor from the right edge, and shows a single box in the upper right corner of the window. If I click that single box, the window finally does expand to full screen, showing a double box in the upper right corner. I've tried all the manipulations I've seen concerning starting screen size (such as going to the shortcut icon properties and indicating the that the program should start "maximized") but I'm still getting this same behavior. Any thoughts? (I'm running Windows 11, with the latest version of Firefox.)

Before I updated to FF 103.0.1, links I clicked on in e-mails in Outlook would open in an FF window using my existing default profile. Since updating to FF 103.0.1, these links open in an FF window with a virgin profile. If no such window was already open (from clicking on another e-mail link) this will be a new FF window, even if FF was already open with my normal profile. As a result, e-mail links to PDFs open the files directly in FF (instead of asking me where to download them to, as I have configured in my profile) and I am missing my stored passwords when the links lead to websites that require login.

This is a real PITA! Is there anything I can do other than revert to an earlier FF version? Please help!

I am running Windows 10 2021H2.

Using Firefox 103.0 on a Mac running Monterey. Since updating to FF 100.0 or possibly 101.0, the BBC News website's videos won't play. I've tried turniing off all privacy/security add-ons and settings but still nothing. Just a grey rectangle with the BBC logo in it (see screenshot).

Safari can play them though. Any ideas?

I set up sync before reinstalling Windows 10 on my PC, currently everything is still intact on my iPhone, but gone on the PC, because I reset my password?

How can I get everything back in Firefox on my PC?

Excuse me, I realize there must have been many similar posts.

Hello folks,

I had 1025 tabs open in FF, in various groups using SimpleTabGroup. Somehow I've managed to get into a situation where, when I start FF, I get just three or four of my most recently used tabs on startup.

I have no idea how to get back to the 1025 tabs I really want, but when I close FF I'm asked whether I want to close 1025 tabs, so hopefully they're still available somehow...

Any advice gratefully received!

Thanks in advance.

NB: Firefox 103.0 (64 bit). Xubuntu Linux.

I reset my PC and reinstalled Firefox last month, but my bookmarks were never recovered after I logged in my Firefox account. A couple of months ago I installed Firefox on another PC (to which I no longer have access) and it showed all the synced bookmarks, but this time it doesn't. What should I do? Thank you

I woke up this morning and my tab bar on Firefox was out of control. I figured out how to shrink the tabs in about:config. However, there is a huge space at the end of the tabs that is completely unnecessary. I've been googling all morning. I tried to find compact mode--but "density" is gone, even when I go back into about:config and enable it. The only other help I found was to change the CSS code and unfortunately, that is outside my wheelhouse.

Is there ANY way I can get my old tab bar back so that the tabs fill the top of the screen as opposed to having a huge empty space at the end?

When I go to my bank's login site, I get a message saying that I need a newer browser. I have the latest version of Firefox, and I used to be able to log in just fine, but I recently reset my browser and I seem to have lost some settings. I have tried adding an exception for this site's cookies in Settings, and I've also tried turning off enhanced tracker, but the site still doesn't work. Is there a way to tell what is broken and then fix it? Thank you.

Since i have my new laptop, i do not get twitter videos, bbc news working. Youtube and vimeo does work! Guess its about html5? Have checked mediasource and javascript settings in about:config and they are okay. Do not have this problem in brave browser.

Anyone has an answer?

Thanks in advance!

I'm a hobby-programmer not trained. My doc is local php file, saving calendar events to text files, run on localhost. The field in question is a line number on my calendar. Javascript uses that number to load another input with the calendar entry so I can confirm that it's the correct line before submitting it to PHP for deletion. I have unchecked 'Remember search and form history', ran 3 cleaners, restarted the computer and the data is (correctly) not displayed. But it is not deleted. When I rechecked 'Remember search and form history' the old input data comes back. If I change id, field name, javascript function name and variable names the history disappears but when I restore those names, the history is back. I want to know why that input can't be permanently deleted. Windows 10, Firefox 103.0.2 (64-bit)

Hi, all websites that have embedded tweets stopped working for me today. I simply see a box that says Loading tweet...

I have attached an image that shows the error. When I am in troubleshooting mode the error goes away and tweets load. the problem is i cant figure out why. Even when i disable all extensions and turn of troubleshooting the tweets stop loading again.

I lost my old session and while attempting to fix the issue I overwrote my sessionstore.json backups in the process. Now all i have are the upgrade.jsonlz4 files, i know those are old session backups from when we upgraded. how do i go about restoring those as a session? when i follow the typical session restore steps nothing happens seemingly because its a jsonlz4 - XXXXXX file.

Any way to change it to a normal jsonlz4 file?

Firefox just changed.

For over a decade I had a Bookmarks tab on my Bookmark menu, and now that's gone away. I have that whole setup very keenly arranged with folders-in-folders and now I either have to futz with several more buttons than I used to, or do a pop-up window with Ctrl+Shift+O to manage bookmarks when all I want to do is go to my bookmarks menu as before, select the right folder-in-folder, and then "Open all Tabs."

How do I get a Bookmarks icon to click as before without going into another menu for do the Manage Bookmarks when I don't need to manage anything? Speed and accuracy is important, and this is neither fast nor accurate without that icon/tool.

Today, web pages started showing small numbered boxes behind each element on a webpage. As you move down the page, the numbers are in sequence. I tried the font settings. They are all set at what they should be. I also tried the config settings, no joy. If I restart in troubleshooting mode, the boxes go away. Note: I am using Linux Mint, and Firefox just updated yesterday to V103.0.2. Any help would be appreciated.

When I am in 1 window, I have multiple tabs open, but when I hover over the Firefox logo in my taskbar, the tabs appear in different windows that have each tab but not the other tabs from the window I am on. Like every individual tab has its own window. This has never happened to me before, only started happening today.

Sometimes when I open a video it doesn't play, it infinite loads with a black screen and I tested it on a separate browser and the video works there

I've tried deleting cache and cookies but it doesn't work

I am pasting this video link first to show exactly is happening when I use Google Images Search results. https://youtu.be/HD-GPkORQPA

This happened suddenly. Everything was fine when I last used google image results, I was playing a game and when I alt+tabbed to search for something, this was happening. I have no idea what could have caused it since I didn't install any new extensions, CSS styles, programs in my PC nor any big changes that would give me an idea of where to start.

I already tried disabling all the extension and that didn't help at all. The only way I've managed to make this stop, was when I opened a private window. There the image search results were fine and I could zoom in, and out and no weird scrollbar issues were happening.

I went back to a normal window in Firefox, and noticed that if I log out from my Google account, this will also fix the issue. And when I logged back in, the issue was happening again.

Anyone have any idea why this would happen, and how I can fix it? Thank you!

Firefox has my credit card information and it shows up in a window when I go to pay for something, but when I click on the credit card I want to pay with, it won't autofill. In Settings, the box to autofill is checked. This has worked a hundred times before, but stopped working a few months ago. Also, I've checked the 2 relevant items in about:config an they are enabled. How do I get the autofill to start working again?

I have noticed issues with; when I download an attachment, i.e.graphics file, that the browser closes.

I have my emails configured where Yahoo and gmail available by selecting. Sometimes Yahoo mail will close and Gmail will remain open, Firefox doesn't crash but somehow closes either gmail or yahoo but not both???
