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 I tried to follow it, but it seems to be badly outdated in certain key respects: esp wrt a setting called "ui.systemUsesDarkTheme" in about:config.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.

Thanks, ~S

Good evening. This might be a tough one and not sure if it is even possible. I have had Firefox on my Dell Desktop for about 6 years. Over that time I have made many tweaks via about:config to get it working and looking as great as can be. I did just purchase a new HP desktop and downloaded and synced Firefox. I was also able to set up the new PC next to the old one to make sure each settings menu is exact. But the appearance is off on so many levels. I have no idea how many tweaks I have made over the years but have no idea exactly where to start. I did not know if there was any way on the older PC with those tweaks made to get a log of some sort of what I changed on that Firefox.

Even with the settings menu exact in both versions I cannot figure out what changes I had made. It's not many but enough. I know it is crazy but here is 2 screenshots. The one on the right, the smaller one in general is from the old PC and how I want it to look. I have tried tweaking zoom and text on the new PC and it has been a disaster, hence looking here.

Thanks in advance.

I am unable to activate the built-in VPN. I am in a loop of getting started -> Activate Firefox’s built-in VPN for extra privacy and protection' then I click 'Continue' and then I get again back to 'get started'. The built-in VPN never activates. I am signed in while doing that and I am using a macbook to run firefox.

The Firefox VPN used to work great. Then it disappeared. When it came back, it asked me to log in so I did. After logging in, rather than letting me use the VPN, it would once more ask me to log in. The attached picture shows what it keeps prompting me.

Firefox 152.0.3 on Windows 10. SVG icons such as Google Maps interstate shields flash briefly then turn into squiggly lines. Same issue occurs when uploading images to websites and viewing Amazon book previews. Works fine in Chrome. Already tried: disabling hardware acceleration, toggling gfx.webrender.all, gfx.webrender.software.d3d11, gfx.webrender.allow-partial-present-buffer-age in about:config, clearing startup cache, removing Tampermonkey extension, disabling Killer Network Manager (CNMNSST.exe). I uploaded an image of how interstate icons show up in google maps.

So I just switched OS on my desktop, and had to log into Firefox all over again for the first time in a bit, and it turns out that for some reason my saved passwords arent synchronising with my whats saved on my phone? In the past my experience have been that if I ask firefox to save my password on one device it remembers it on all my devices. Is this not the case? Is there something I need to do to manually synchronise?

On an email chain that started about 10 minutes ago, I suddenly can't respond, getting a message that a pop-up blocker of some sort prevents it. Plus the message opens up on a different page with it as the only tab. I didn't make any changes, as far as I know. How can I get gmail to return to the way it was 10 minutes ago?

Place a remove icon, not a delete app icon, in the three dots for the icons on the landing page.

Your last update placed 24+ hot links on my landing page. If I click on the 3 dots or right-click on the icon, there is no removal option. How do I get rid of the background app icons on my landing page now?

I'm running Firefox on Win10 with no options to upgrade to 11. Since the latest firefox update installed, I'm getting a screen that says "Oops, something's wrong," and then I'm kicked out of gmail. A screen asks about sending a report to Firefox, which I check OK for. Today this is happening about every minute to 30 seconds . What needs to happen?

Tell me why they're trying to do this? I'm confused how. Firefox starts about 30 seonds later(Im viewing thru windows 10 filemanager) and stops google. I do not let google or edge start on boot. This only happens from wake after sleep. I believe only 5 or 6 days has this been happening. Any ideas?

Swiping left with two fingers is the same as going back, but I keep doing it accidentally. I thought there was a setting for it, but I can not find it now. Is there a way to prevent this from happening?

I am using the current version of Bazzite. When I run Mozilla VPN, I just get a blank window for a few seconds, then it asks if I want to force quit. Uninstalling and reinstalling, and restarting my PC, do not seem to help.

I recently reinstalled Bazzite on this PC, and Mozilla VPN was working on my previous install.
