I'm not very computer savvy but I followed a website a few months ago to edit Firefox so it'd default to dark mode. I think I went in and edited source code? I can't find the instructions anymore but I'd like to revert back to the original setting. How do I do that? I tried to refresh Firefox but it's still coming back with some websites in dark mode and some not. Please advise!

I am unable to log into facebook after inputting my password and 2FA. disabling all addons does not help. It is stuck on the "This was me" screen in an infinite loop.

since the last update, the shortcut keys to highlight a word at a time left OR right are both highlighting the next word AND also jumping to the last tab. AGAIN! I noticed this was identified as a problem back around 2019 in a search. I now cannot move fluidly within text, nor highlight a word at a time quickly. Either it's whole line or simply a letter at a time... which results in a pretty incompetent, crippling experience. PLEASE FIX!!

I have an iMac with Sonoma 14.3.1 with Firefox 115.9.1 esr . It is for personal use, not for a business. I just learned that there is another Firefox version (124.0.2) which is not esr....

Which version should I use and why?

If I should use the "normal" version, how do I replace the esr version with the "normal" one ?

Thanks.

Hello, i've updated the Firefox browser to version 120 and since then polish texts in browser are broken. How can i fix it or restore to previous working browser version?

I'm trying to connect to my Schneider XWPro Gateway for access to my solar inverter, and security policy on Firefox no longer't allows access. I can access using Safari by explicitly allowing access. Error from Firefox is as follows:

Secure Connection Failed

An error occurred during a connection to 192.168.1.120. You are attempting to import a cert with the same issuer/serial as an existing cert, but that is not the same cert.

Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem

Your error message states there is a problem with a certificate conflict, however there is no apparent way to tell which certificate is causing the conflict, so there is nothing I can do about it. This is a new problem, I have been able to access this device in the past.

Any suggestions?

Just switched to firefox as my default and found that I can't sign in to netflix. It always gives me the "incorrect password" message. I've tried resetting the password, clearing cookies, restarting, turning the DNS proection off, restarting my computer, etc to no avail. Anyone else have this issue or know a potential solution?

My elderly mother has twice (in the last month alone!) been scammed by selecting the first thing that comes along in a Google search. I realize this is simply never going to change, and I need to take steps to prevent her from ever seeing any sponsored results of any kind, or any kind of address bar autocomplete suggestion.

I have taken several dozen hours of my personal time this past month to repair the damage from her first scam experience (that I know about!), and today's incident made me realize that I have to do much more customization of her browser than I previously imagined. When I told her to never fully trust a Google search, her reply was "but I used Firefox!", and that told me everything I needed to know. It simply cannot be left to her understanding of the internet.

The intended setup is an iPad and a Win11 laptop. I would like to set up Firefox so that the address bar is nothing but an address bar without any kind of autocomplete at all. Is this even possible?

Also, I obviously can't filter every scam known to man, but I would like to specifically block the kind of pop-ups and ads that scammers use. What is a good strategy for this specific purpose? I don't care about legitimate marketing ads, even though they're annoying to me personally.

I have a M2 Max Pro MAC. I have read other posts about this and people suggest starting in safe mode doen that and it still happens. Removing all pluggins and restarting doen that and it still happens. IT doenst happem on any otehr browser.... help please?

For the last couple of weeks, whenever I access the finance.yahoo.com/ website, my computer slows to a crawl. I run Activity Monitor to show me FF memory usage has surged to 6.5 GB! I cannot just 'quit' FF, have to force quit to regain the memory. No problems with any other website. I am running Mac OS 12.7, 8GB RAM, FF 102.0.1

Any help/suggestions appreciated.

I am using Firefox Developer Edition in a work environment that only saves directories between weekly restarts by explicitly managed rules. As a result of some missing folders from my weekly restarts, I need to sign in to my Firefox account and enable sync each week. Currently my machine retains the %APPDATA%/Mozilla and %LOCALAPPDATA%/Mozilla directories + children.

What other directories are needed by Firefox Developer Edition in Windows to retain the user profile/syncing, et. al.?

Thank you for your time!

Every time I go to Fox News, the video at the top of the page drops to the lower right-hand corner. It's an annoyance I've been searching for a way to eliminate. I have pop-ups blocked in preferences and I have a couple of different pop-up blockers, but nothing seems to work. I'm currently using Firefox 114b.09 on a Mac Desktop.

I frequently open new tabs by right-clicking the current tab and choosing "New Tab" from the context menu. Naturally, I want to start typing a URL or search term.

But the focus/cursor/caret is nowhere and typing does nothing. I have to click on the address bar, and then I can type.

I'm not using New Tab Override and I have Firefox's new tab set to a blank page.

I tried disabling all my add-ons, but I still had the problem.

I tried setting new tab to the Firefox home page and for a short while I got a cursor in the address bar. But the problem returned after a few hours

Any clues on what might be wrong? Firefox version 120.0.1 (64-bit) on MacOS Ventura 13.5.1. Thanks!

(A similar problem is described here: https://support.mozilla.org/en-US/questions/1420220 -- but in my case this is not a container tab.)

Hi, I would like to customize the apps that firefox shows me when I click the address bar. In the attached image, you see youtube, google, reddit, wikipedia, twitter. I would like to remove some of these apps. How can I do that?

Also, there are suggested search engines on the bottom, including amazon, bing, ebay. How can I customize the apps which appear in that list? Again, I want to remove some of these apps.

Thanks.

I am using MacOS Monterey 12.7.1 with the latest Firefox version. When in full screen mode, if I want to refresh the screen I move the mouse pointer to the top of the page to get the tools to display but when I move it down the the refresh button, it quickly hides again before I can refresh the page. Does anyone know of a solution to this or a keyboard shortcut I can use to do a page refresh while in full screen mode?

Having a hard time trying to figure out why Firefox View would be completely empty every time I check it (see attached image). I use Firefox all day long on my desktop and phone. My account is synced on both. Is there a settings I'm not aware of?

Thanks for help.

and not only that, when I click on sign in - it shows me a work email address that I rarely use - not my Firefox account / main email. I have to click NEXT then change email address from the drop down menu. I followed the setting attached. but it's still does it. I close Google tab, then go back and im signed out again! It's extremely annoying. How on earth can I fix this?

My tech info: Macbook Air Mac OS 12.2.1
