macOS Tahoe, Firefox 152.0.3 macOS settings include "Appearance - Auto"; i.e. system switches from light to dark at sunset. While the "top area" (tabs, address bar, bookmarks bar) of Firefox follows this - some of the pages themselves do NOT???

I found this website which was at top of the search results. I tried to follow it, but it seems to be badly outdated in certain key respects: esp wrt a setting called "ui.systemUsesDarkTheme" in about:config. I set this to "True", but may have screwed this up!! First question: Should I "reset" this somehow?

Finally: To get at the primary question, there are two "sub-questions" that may explain my confusion more clearly:

1. Is there no ***simple way*** to get Firefox & webpages I view to follow macOS Light/Dark appearance?? What are the CORRECT steps?

2. Do individual webpages have the ability to "decide for themselves" whether or not they will adhere to the system light/dark settings. This may well be an officially "stupid question", but while "most" webpages remain "Light" (including this Support page), a few pages appear dark.

In the past couple of weeks I've noticed this happening a lot; particularly in YouTube. Menus don't show items (regardless of appearance color mode) until I refresh the pages, or thumbnail images fail to load. Sometimes the images will load after waiting for several minutes. Drop down menus won't sure their items unless I refresh the page.

I tried Microsoft Edge and the problem doesn't exist there. I prefer Firefox, but don't like these annoying glitches.

I've also noticed, again on YouTube, if I'm watching a Playlist, the comments under the video are not shown IF I have the playlist open on the side, but if I close the playlist or change the video mode to Cinema Mode, the comments suddenly reappear.

Again, this issue doesn't occur if I use the Edge browser.

I've ruled out my BitDefender Internet Security App and its VPN.

Thanks in advance for any help.

While I was using Firefox, the inspector console window started opening and closing all of a sudden. Whenever I try to click on a different tab that is not the one I am currently on, it switches back to my current tab. This issue also occurs on other Firefox-based browsers, and not on any other browser I have installed.

I attempted to change the theme, I went into Safe/Troubleshoot Mode, disabling my extensions, etc, but nothing changed. I've restarted my computer twice already, and yet it doesn't seem to change anything.

The only way I could temporarily halt it was through holding Ctrl, Alt and Shift at the same time, but this only worked for as long as I held all three keys down. What should I do about this?

Hello Im using multiple firefox edition on my PC from beta dev to nightly, and recently in nightly and only nightly I've spotted strange issue that appears as window in window screenshot attached, outer x to close or maximize window does not work only the inner and mostly goes after F11 full screen and then return to normal. Troubleshoot mode and restart does not change or fix this.

Earlier. I purchased the annual subscription for Mozila's VPN. But after finding out it impacted my browser's performance negatively, I tried to cancel it. It got cancelled. But I haven't been refunded yet, and noticed that the card number on the receipt is completely different than the one I used, in fact. None of my cards have the number shown.

I changed my browser to the latest version of Firefox, but then I lost all streaming websites (youtube, Netflix), and password autofill. Luckily I had 2 firefox browsers so on the other one I did reset and can steam again there, but I lost several shortcuts and other extensions such as autotranslate. It's just gone. Colors and pictures are on both. And I can't change back the browser that has the newest version. So now I'm stuck switching between browsers depending on what I want to do. Wish I had never changed that browser. Has ruined my computer. I've spent days trying to fix and change things.

I have been with Firefox for over 20 years. The main reason is that it has always performed exactly the way I wanted it to. Just now I got a notification in windows that "Firefox is now configured to startup when you log in" WHAT THE HELL ARE YOU THINKING??? This is EXACTLY why I have used Firefox for so many years BECAUSE IT DID NOT RUN IN THE BACKGROUND CONSTANTLY!!!!! When I close something I want it OFF completely. I use a key manager and sign in and out as I need to and the LAST thing I want from a browser is it constantly running. I am an IT and systems manager and my primary reason for owning a PC is audio and video production. Background services cause issues with high performance real time audio systems which is exactly why I run windows server 2022 on all my workstations. This is also one of the biggest issues with Windows 11. Edge is one of the first things that I remove from an operating system for that same exact reason, and is also the reason I dumped Chrome nearly 2 decades ago. The recent changes I have been seeing with Firefox have been tolerable but this breaks that. I surely hope that is not the future or I will be searching for a new browser to use, even if it has to be a portable. I just want to know WHY?

"Access Denied" when accessing homedepot.com and lowes.com using microsoft edge or firefox within windows 7

I believe when I wanted to update to a newer Firefox version, I chose the one right before the change to tab history where it said something about not saving as many presumably due to websites that can open several pages within a tab in a second or 2.

I don't know if this is the cause, but now whenever I open several YouTube pages it can fail to save one of them to web history. I don't know if it's because some pages open a &pp= page first and then when it switches to a clean video ID URL Firefox doesn't log all of them because of that tab history change?

Either way I'd also like to revert that tab history change if it's not the cause, is there already an about:config setting? Or is this just like the tags-in-history-window change and it will never be re-introduced..

I'd probably need to update Firefox within a few years anyway when some new thing unsupported on older Firefox is introduced, so if I revert to v131 that works better I may be in the same position a few years later. Idk if I can revert with the current profile data anyway.

I'm on Windows 11. After I added some plug-ins and extensions to replace the ones that went missing during your last update, my bookmarks also went missing. (They were there before I replaced the plug-ins and extensions.) I followed your instructions on how to access my bookmark back ups, and found them. However, everytime, I tried to install one of the backups, I ended up with no bookmarks at all in Firefox.

Please help, I have no access to any of my accounts!

Thanks,

Charlotte

Hello. I recently started using the built-in VPN in Firefox.

According to the Use built-in VPN in Firefox information page, I should be able to see the data usage in my Settings. However, when i look there, I can see "Manage websites" block and the "Get more protection" block, but I cannot see the "Monthly Data Limit" indicator that's supposed to sit between them.

I am running Firefox 152.0.4 on Windows 10

Am I looking in the right place for the VPN data usage? Is there another place to find the Data Usage?

Thank you.
