I have the same issue that was reported here: https://support.mozilla.org/en-US/questions/1358340 and here: https://support.mozilla.org/en-US/questions/1409149

After a Firefox restart for a version upgrade, there are 8 windows listed in the Windows menu, but only 4 are visible. Trying to select one of the invisible windows from the window menu, or cycling through open windows with cmd-` displays nothing. I tried checking other desktops to see if the windows had landed there, but they're not. The missing windows don't show up in Mission Control.

I also tried exiting FIrefox, deleting the xulstore.json file, and restarting. This had no effect.

I'm on a 2021 M1 Max MacBook Pro Firefox 117.0.1 Mac OS 13.5.2 (22G91)

Any ideas? This is a weird one.

Thanks!

I've downloaded and installed and updated Firefox on a new windows 11 PC - and I have a perfectly working installation on my (old) windows 10 Machine, so I'm well used to the browser! I've downloaded, installed and enabled three core, up-to-date addons: IDM, Adaware and Internet downlad helper: however NONE of them show on the toolbar and none of them function. And I've tried (I hope) all internet-search-suggested remedies such as reset Firefox etc. ad nauseam. All without success....

HELP!!

Every time I open Firefox Bing comes up. How can I get rid of Bing completely and forever? I hate it ! I don't want it!

I've tried going through add-ons, I've tried deleting all of the Bing files that I can find.

HELP!!

PLEASE!!!

I am told to disable pop-up blockers in order to have a payment verified. I do not know what pop-up blockers are, I do not know where they are. When I go to Settings and search for pop-up blockers, I am told "Sorry! There are no results in Settings for "pop-up blockers"; and instructed to visit Firefox Support. I have been sent on this circular quest three times now. Please help me.

When a bookmark is made, there is no option anywhere to add tags using windows 11 - I had no problem with tagging bookmarks using Firefox in windows 10, but that option is not showing up for me in windows 11. I have refreshed Firefox with no success to try to correct this situation - thanks in advance for any help you may provide – del

Good morning I was using firefox on windows 8.1 I moved to Windows 10 and after logging in to my Firefox account, my bookmarks and passwords from the Firefox sync service were not restored.

please help,

Hello,

I noticed past few months I'm getting this message from cloudflare after using certain websites while using Firefox on Desktop. I have refresh Firefox every time this happens I tried disabling my adblockers, lowering settings, and disabling my Pi-Hole the issue still persists. Does anyone know what the issue might be or someone else experiencing this?

I use Firefox on a PC to access Facebook (website, not app). This week the Messenger/Chat feature stopped working. I click the icon and it opens but nothing appears in the box, it just hangs. There is an option to open in its own window, but that also is blank - no past messages, no contact names, no ability to start new message. When I log onto Facebook in Edge, Messenger works fine in Facebook.

I've tried everything I found on the internet for this issue - updated and refreshed Firefox, cleared history/cache/cookies/site data, uninstalled and reinstalled Messenger, refreshed Facebook to initial settings, used Firefox in troubleshooting mode, reset everything, turned off browser, turned off my computer, used shift key to reload tab - nothing has worked. There are some instructions about stuck cookies, but I didn't understand them so I didn't try that one thing. I've gone into every menu I can find to try to figure out this issue, which isn't the end of the world, but I would appreciate some other ideas for what is suddenly causing this. Because now I have to redo all of my settings and preferences and logins and the problem still isn't fixed.

When I doubleclick an image in Azure DevOps, it's supposed to open fullscreen in a popup/tab. That popup opens, and immediately closes afterwards.

How do I fix this?

Popups are explicitly allowed on this site, but it doesn't make a difference. I have tried turning off content blockers, and changing between strict and standard privacy settings.

I don't really want to go on a wild goose chase and try a billion different things. Rather, I'd like to know how to diagnose this. So how can I know what mechanism is responsible for closing the popup. This will allow me to narrow my diagnosis a great deal.

It would also help to know how I can 100% prevent anything other than the user from being able to close a tab. Just to test what happens inside that popup. Because how can I know what's going on in a popup that lives for a few milliseconds? I'm not that fast.

This is a Question for the Developers, and other Hackers!! Video Streaming Not Playing (Disney/Hulu/Prime/Vudu) Anything that uses Digital Rights Management (DRM) Content... YouTube works fine.. oddly..

I troubleshooted Resets,clearing cache, spoke to support from Disney on the phone, and finally reinstalled windows. Everything works.. Then applied my drive space hack. And everything is broken again.. Simple Hack, got the idea from Linux. I changed the C:\Program Files & C:\Program Files (x86) into Hard-links/Junctions to the D:\Program Files & D:\Program Files (x86).. And now the videos will not play... There must be some coding that monitors the Drive letter, maybe for pirating protection, I have no Idea... But I'd love to at the very least know why this happens.. I will plan to upgrade my SSD in the near future to prevent the need to move Program Files, It's just really annoying that a simple thing like steaming is now broken because the programs are installed on the D: Drive... Like WTF is going on.. Anyway, if someone has some incite into why, and a possible work around that would be great.

Thank-you very much if you read this!!

I was watching Youtube when my audio suddenly cut out. My speakers are fine - audio on other browsers or on local videos work perfectly fine.

I've tried refreshing Firefox and clearing cache, but neither of these work.

I wish to add a new PC to devices I am currently syncing (a "legacy" PC, a laptop, my iPhone). I can confirm from the legacy my correct password and can log in using it. I have installed the up-to-date Firefox on the new PC. When I attempt to log in to Firefox/sync on the new machine, it will not recognize the confirmed password. FYI, this is a new password created Aug 23. The new machine runs Win 11, the old Win 10.

When Firefox is launched to maximized, the Windows Taskbar does not display when the Taskbar is set to Hide. Firefox takes over the entire screen. When I use two monitors and Firefox is on the second monitor it the toolbar is visible.

How can I stop this from occurring?

I use a website from the USPS and have for 20 years. Now, about a month ago, it will not load my sign-in page. https://reg.usps.com/entreg/LoginBCGAction_input?app=EadminAPP&appURL=https://gateway.usps.com/eAdmin/view/signin/loginCheck This the site I need to run my business. Why, all of a sudden, it will not open. There is no error message. It just keeps trying to load the page. Firefox is my browser of choice by a lot, but if I can't do my work, I can't use it.

Hello.

My name is Kris and I have been a life-long Firefox user. Recently I have come across this great Firefox Onebar CSS style, which I have become obsessed with: https://codeberg.org/Freeplay/Firefox-Onebar, which aims to modify the Firefox default appearance. I have installed it according to instruction and introduced few tweaks offered for consideration iin the aforementioned link:

• onebar.hide-all-URLbar-icons
• onebar.disable-https-truncate
• onebar.disable-single-tab

This is the most far I have gone without further ruining the browser by manually editing the Userchrome.css file.

Could I please request your help with adjusting said file content to make minor changes? My expectations are to leave everything untouched besides the following:

• all flexible spaces are removed
• the Extensions button is removed
• the List All Tabs button is removed
• the Home and Refresh buttons are permanently visible and aligned to the left of URL bar, followed by conditionally visible Back and Forward arrows upon their activation (they seem to be in the URL bar already however are invisible)
• the Hamburger is permanently visible and aligned to the right of the URL bar(it seems to be in the URL bar already, but is invisible)
• the search box is aligned to the left, but is preceded by Home, Refresh buttons and Navigation arrows

The Navigation arrows and Hamburger menu invisibility issue might have to do with the colour that has assumed the same one as the theme URL bar background.

If you could please modify that style for me, that would be so great, indeed. I have been obsessed with that ever since I have discovered it. Alternatvely, please direct me to a forum/IRC channel where I can place that request.

Thank you, hank you, thank you. Please, respond. Kris.
