Everything is gone….bookmarks, passwords, history on my desktop computer and I have no idea why. I opened Firefox and the home page was different and then noticed nothing was the same. I dl Firefox again, no help, same result. I do have my desktop synced to my iPad and laptop but I’m concerned they will import from the desktop and get wiped out. Is there a way to sync from the laptop to the desktop? I am at a complete loss on how to fix this. I do run a backup on this computer. Would that help? Restore point?

Many thanks,

Len

I frequently attempt to open news articles or other pages requiring form fill-in but instead get a page that advises me to disable an adblocker. I have no idea what Firefox (yes, up-to-date) uses or how I could set it to allow pop-ups for a particular site. Help!

I am on a brand-new machine and having trouble setting up the Firefox browser.

When I click on a link it opens in a new window with all the tabs ready opened.

How do I open a tab without opening a new window?

Also, how do I set Yahoo.com as my default search engine?

Thank you for sharing your wisdom

When I launch teams or slack from firefox on windows, I presume that a slack:// and teams:// or equivalent url is launched by the webpage.

As a developer working on Browser Picker, it would be quite handy if I could inspect these urls that gets launched, is there a way I can see the actual protocol url that got launched somewhere?

Today when I close many tabs using control w firefox seems to randomly jump around when choosing which next tab to close

I wish to have firefox always close the adjacent tab to the tab I just closed

This should be the default behavior ... I do not see any setting for this ... is there an addon to do this ?

I am using the latest firefox on ubuntu

• • • UPDATE*** below answer for setting `browser.tabs.selectOwnerOnClose` has no impact on this

I use Outlook.live.com Hotmail and recently a PopUp Message appears asking me to:

Add outlook.live.com as an application for mailto links.

Microsoft Customer Service said it was not something they initiated and likely a Firefox issue.

It does not seem safe to click on a random link like this without any explanation. Each time I log in, the same message appears.

Could someone please explain what this is for and how I can stop it from popping up each time I log into Hotmail?

when I click on the firefox icon to load it takes me to my home page, but within 20-30 seconds it loads firefox again. it is very frustrating when I.m starting something and firefox loads again taking me back to home page. I have to go down to the bottom and click off the second firefox. I don't know how or why this started. Thanks for any help.

i am setting up a new laptop and trying to import all my current data from my old pc. Nothing is right. It imported alll the shortcuts on my toolbar from years ago. None of these are the current bookmarks from my old pc. ive tried syncing, importing again, nothing works. my bookmarks on my side bar are years old. I dont have ANY of these on my old pc as i deleted them years ago. what the heck is happening and how do i get my new pc browser to look exactly as my old pc looks. This is very frustrating. I have over 500 bookmarks on my sidebar. it looks like every bookmark i have EVER used. This is ridiculous.

From today 4 march when I try to record a voice message on chat from facebook appear an error saying an error as occurred. On Chrome it work, from facebook app it work

I even tried other facebook ids and firefox profiles and ever the same. Even disabled the anti popup ublock

In all case I haven't added any conf or adon or other inside firefox, I use same conf as ever and from many years.

Today messages from microphone in chat does not work and facebook say an error occurred Is written in italian but say what I said

Hello. I have a pretty big sprite image i am trying to display on my web page but mozzila wont display it. The sprite is 78016px by 1000px and im cropping it to be 736px by 1000px. Sprite is made out of a png sequence that was made in 3d software, now the thing is when i put in the non rendered verson of images(3D viewport colors) which windows labels as 8bit (maybe because of less colors) it gets displayed, but when i put the rendered version which windows labels as 32bit image it wont get displayed on Mozilla. It gets displayed on Chrome and Edge without any problems. The only difference beetween the images is that the rendered version has a transparent background behind the subject...they are the same sized sprite. I will drop the first frames of the sprite in the images section so you can get a better idea. Also all of the code and images is stored locally.

I installed an OBS plug-in for a virtual camera so that I could film my screen and pretend it's a webcam. I was able to use the virtual camera or my webcam on spelltable.com by selecting either from the dropdown "allow" menu. One day, I was no longer able to select my webcam. I could only select the obs virtual camera. I switched to MS Edge which worked as normal. I've uninstalled OBS and all plug-ins. Same result I've reinstalled firefox. Same result. I've been using MS Edge for websites that need my camera.

For some time now, Firefox has been unable to display quotes on Yahoo Finance; for example:

https://finance.yahoo.com/quote/MSFT/

The space where the price history graph for MSFT should be is blank except for a message saying "Loading chart for MSFT". The chart never loads. Sometimes Firefox issues a message saying that the site is "slowing down Firefox".

This happens for *any* quote, no matter what the ticker symbol.

I have tried running Firefox with a new profile, running in a private window, and running in Troubleshooting mode; the behavior remains the same. Clearing cookies and changing the tracking protection setting has no effect.

Oddly enough, when I attempted to report this page as not working, I couldn't submit my report (the Send button did nothing -- though this feature works for other sites).

Have others here experienced the same problem; and if so, is there a known cause/resolution?

Thanks in advance for any help.

Please see the attached image.

Firefox believes I have a security key.

What is a security key? Where do I find it? Why does Firefox think I have one?

And why is there no helpful information to explain this confusing UX?

Since about one year I am unable to use Japanese input only in Firefox. When I try to switch with fcitx and control+space, nothing happens. However, fcitx-mocz works everywhere else on my computer (i.e. terminal, thunderbird, other browsers, etc.). Furthermore, I uninstalled fcitx and everything associated with it and reinstalled it according to this thread: https://support.mozilla.org/en-US/questions/1367181 (just with mocz for Japanese). This also didn't change anything. Any help is appreciated! My system: Operating System: Linux Mint 20.3 Kernel: Linux 5.15.0-91-generic Architecture: x86-64 fcitx version: 4.2.9.7 Mozilla Firefox 121.0

I can't open firefox. message says "firefox quit unexpectedly" and it won't reload. I tried Force Quit. I tried restarting my computer. I tried completely shutting computer down and restarting. It happened very suddenly yesterday.

This happens on other websites as well: https://www.exploit-db.com/

Can you help?

I just got a chromebook! Details:

Device name: Lenovo Flex 3 12.2" chromebook, 8GB ram. Intel N100 Device code name: IP Flex 3 CB 12 (pujjo, version 123.15786.0) Firefox version: 124.0.2 (flatpak) OS version: Version 123.0.6312.112 (Official Build) (64-bit) Chrome: Version 123.0.6312.112 (Official Build) (64-bit)

When I watch a youtube video with chrome my cpu usage is 20-30% When I do the same with firefox my cpu usage is 50%

Running `about:support` and going into `webrender_compositor` I get the following errors under `env`: 1. Blocklisted by gfxInfo 2. Blocklisted; failure code 3. FEATURE_FAILURE_WEBRENDER_COMPOSITOR_DISABLED

I have set almost all these force renders = True and even granted gpu access to firefox flathub but still no difference in performance. I am asking now because I am just going in circles in the rabbit hole.

After years of accessing www.youtube.com with Firefox with no problem, the website is no longer accessible as of yesterday. When I point my browser to that URL, I get a screen with greyed out video previews, greyed out titles, greyed out account access and a search window that does not do anything. I can access YouTube just fine with Safari. I've cleared my cache. Please advise.

Hi,

How do I change the color of the white border and the color of the arrows?

I have menupopup > menu, menupopup > menuitem { -moz-appearance:none!important; color: white !important; background-color: #1551C0!important; } menupopup { -moz-appearance:none!important; background-color: #1551C0!important; border:none !important; padding:5px 0px 5px 5px!important; }

I have .menu-right { filter: invert(100%) !important; but it only turns the arrows white in some locations but not in the bookmarks menu and not in the right-click menu.
