When I open Firefox. Firefox Will NOT open any websites. If I disable ublock origin then enable again Firefox works but I get all the ADS. What I have to do is: Close firefox and restart Firefox but then I get this message "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." Sometimes I have to restart Firefox as many as 10 times before Firefox works. I got to the point where I stop after the second try and just switch to Brave browser.

Before: Firefox use 99%. Brave Use 1% Now: Firefox use 75%. Brave use 25%

I made the mistake of installing Norton Private Browser on my Win10 laptop, and it took over the browser extensions as the default program. I tried making Firefox the default browser again and Windows took me to the Settings menu. Firefox is no longer in the list of browsers. Is there a way to fix this situation? Thanks.

I have three accounts on X/Twitter that I frequently have to switch between. I've just recently migrated to Firefox, but I've found that I cannot switch between these accounts. Whenever I click on another account in the account switcher, it stays on the account I am currently logged into.

Attempted solutions:

• Refreshed Firefox (temporary fix)
• Uninstalled uBlock Origin (temporary fix)
• Uninstalled all extensions (temporary fix)
• Clear cache/cookies
• Troubleshoot mode

Hi I have a problem with the configuration of my Firefox. (I hope it is not something more serious like a malware or a security break)

Firefox version 124.0 (64bit) Os: Windows 10 Pro (64bit) 10.0.19045 Build 19045

Step to reproduce

1. 1. I go to: https://wwws.tesoro.es/index.aspx (website of the Spanish gov)
2. 2. I click on the link: Cl@ve in the center of the page (that should bring me to https://pasarela.clave.gob.es/Proxy2/ServiceProvider)
3. 3. I receive an error page "Did Not Connect: Potential Security Issue" "SEC_ERROR_UNKNOWN_ISSUER" (see the attached screenshot)

Things I tried

• I followed the same steps on Chrome on the same machine

The website works

• I followed the same steps on the same Firefox in Incognito mode on the same machine

The website DOESN'T work

• I followed the same steps on a completely new Firefox profile on the same machine

The website DOESN'T work

• I followed the same steps on Firefox on a different machine (same Firefox version, windows 11)

The website works

I get this error in my console XPCOMGlueLoad error for file /usr/lib/firefox/libmozgtk.so: libwayland-client.so.0: failed to map segment from shared object Couldn't load XPCOM.

I keep getting Review Your Global Privacy Control preferences message, almost every time I start the browser. I have selected "Don't Allow" option many times and have also went and managed my privacy controls. But, the popup message won't stop coming.

How do I stop the popup message?

I have been Firefox/Mozilla user from the very early days but I am at a point where I have to stop using it because of this annoying popup message.

Outlook.live.com disrupted by Mozilla multi-container extension. Loads fine when extension off. When extension is on, shortcut that normally loads outlook already signed in now brings you to main microsoft sign on page, but starts launching multiple tabs ad infinitum after you log into that page. Works fine on Brave and other browsers. Started about a month ago. I see no recent complaints in searches. None of the fixes offered in older queries found in searches worked. Are Microsoft and Mozilla having a data access battle? How do I fix this? Really don't want to reinstall Firefox - this will involve hours of re-configuring. Thanks.

Hi, All my tabs and many pages are appearing in an unreadable nonsense font. This page is ok, except for the tab and url; others, such as the settings page, are entirely garbled. When I copy a snippet of this and paste elsewhere, it shows up as English; so it is a display issue, not a new language.

This started on booting the machine today, after some OS upgrades yesterday. (to OS 13.1). I've tried restarting FireFox.

I can't read the settings page well enough to change much there. But this seems like a different issue anyhow. Help please!

thanks Sarah

why do my add-ons keep getting disabled?

ff keeps disabling add-ons that i have used for years and even keep a v. 5 to use the older add-ons and use the latest ff developer to use w/ more modern websites. ff even disables add-ons that worked perfectly well in ff developer and does not even give me the opportunity to re-enable them like i could before.

is there any way to force my old version to let ME decide what i want disabled/enabled?

After updating my openSUSE Firefox package from version 122 to 123 every frame inside each window started to have weird grey overlay of scrollable area. I failed to find any description of such a thing happening, let alone how to get rid of it. I tried removing build-in distro-default preferences and had complete audit of all my custom preferences in about:config but none changed that behavior. I even updated to 124b4 but this also haven't changed anything. Naturally, nuking entire profile is not an option, I might as well replace the whole browser. So, how do I get rid of this thing?

Macbook Pro, Sonoma 14.1.2. I updated Firefox in the beginning of March. Since then it will not allow me to access site on the internet when I have ExpressVPN enabled. ExpressVPN works with Safari. I have spent over an hour working with a VPN tech. It's fine. The only change was updating Firefox. Since then I have removed and re-installed both Firefox and ExpressVPN. How do I resolve this?

I've been using Firefox and it's saved numerous passwords. However, these disappeared suddenly. Through testing, I discovered they reappear when I restart Firefox in Safe Mode (achieved via about:profiles => restart with adds-on disabled). Yet, re-enabling add-ons (restart in normal mode) causes the passwords to vanish again. Interestingly, disabling the add-ons in normal mode doesn't restore password access.

Looking for solutions or insights.

At one site that I visit daily where multiple pictures sometimes can be scrolled horizontally, I can't scroll down or up with the keyboard. The Page Up/Down keys change their functions and scroll the pictures horizontally instead of making the page scroll up or down. I have to use up/down arrows until I reach a point where there are no multiple lateral pictures to get the expected function from the scroll keys. Is there a setting or other way to prevent horizontal scrolling using the Page Up/Down keys?

Gmail and my Google account are stuck on the help center pages. I can't sign in or out and can't reach my mail. Both work fine in other browsers. I tried the "about:support" page with no results.

All of the files I try to download fail immediately. Even extensions will not download on firefox. I have uninstalled and reinstalled and checked the download location. Downloads work on other browsers such as Chrome fine but nothing will download on Firefox.
