How can I change preferred theme from light to dark with resist fingerprinting enabled? I already tried to change "layout.css.prefers-color-scheme.content-override" to 2, but this did not help.

How can I (we) disable enhanced tracking so it's not loaded at all in the browser, i.e., we manually turn it on and off when needed? After this last update, some websites I visit are automatically crashing, the screen freezes, I cannot click on their navigation or products, it's become a horrible nightmare and it's not a good use of my time. I want to disable it.

Good day everybody, I am new to Firefox. I have MacBookAir 11. I added the Ecosia extension since it's my main search engine. I noticed there aren't ads popping up for Ecosia. That is how Ecosia makes money for it's sustainability projects, so, as nice as it is to not see ads, I would like them to show up for my Ecosia searches. I understand you can make an Enhanced Tracking Protection exception (and I did), but where can I find a place to make exceptions for whatever AdBlock software came already integrated to Firefox? I am liking Firefox so far. Thank you everybody. Miran.

Security misconfiguration website will not allow Firefox to display the page if another site has embedded it.......appears after click on the site. How do I clear or correct this for access?

Pages of text but I don't understand what the [expletive] you are doing or why! It's incoherent! Don't tell me what to do without telling me HOW to do it! We customers are not all software engineers. Unfortunately the software engineers who write everything I've been reading haven't learned that. I constantly read stuff that use terminology that is not self-explanatory. Then I'm asked to make a decision that is so badly defined that I have no idea what I'm deciding! SPEAK PLAIN ENGLISH!!!!! Don't ask me to choose among a list of options that YOU have defined, but none of which have any relationship to what I need to know. The "which topic" box just above this one is a perfect example. It took me a long time to even find this opportunity to speak to you! Choosing between incoherent options does not advance clarity for me or knowledge for you. Just stop using computer lingo and speak in a manner that would be understood by a 9 year old, or in my case, a 79 year old retired mechanical engineer. Thank you for giving me this opportunity to actually vent my frustration at what I run into on a daily basis, not just with Mozilla. Tom Riddering, [email address]

P.S. This whole incoherent mess this evening started when I tried to authorize McAfee to protect me from trackers, just exactly what that means I'm not sure, but it sounds bad. It's not at all clear just what would be tracked, who would bother tracking me, and why I need protecting. My life is so utterly boring.

I am not being allowed to access some websites because of my 'Do Not Track' status still being broadcast. I had the field set to 'Yes' when the field was removed. I am not allowed onto these other sites because of my 'Do Not Track' status. How can I fix this ? I was planning on using Firefox when I go to Apple silicon later this year - but not if I keep running into problems before I switch.

Enhanced Tracking Protection is preventing access to x.com even after it is allegedly "turned off" for this site. I have been using personal computers since the 1970s after the IBM PC was introduced, but now I am about ready to ditch Firefox AND Windows 11 to install a decent version of Linux. Grok on my iPhone 8 offered several suggestions to resolve this issue, but none of them have worked so far... including trying to us Microsoft Edge instead of Firefox.

Just checking Facebook "download your information" and got this:

```

     {
       "timestamp": 1781017200,
       "label_values": [
         {
           "label": "Date",
           "value": "2026-06-09"
         },
         {
           "label": "Business or organization",
           "value": "Firefox",
           "description": "The business or organization that added you to a Custom Audience"
         }
       ]
     },

```

Is this actual Firefox passing my info to Meta, or some Meta scammer pretending to be Firefox?

On that date, I had Global Privacy Control turned on in Firefox.

Firefox is supposed to be replacing copy without site tracking with copy clean link however the new Firefox download has copy clean Link greyed out!!

I will continue to dismiss the update until there's no longer an option for me to do so at which time I will just give up using Firefox and try using a different browser.

Hi, I am experiencing an issue with accessing my Amazon orders and returns when using Mozilla Firefox. While I can navigate to Amazon.com without any problems, I am now prompted to sign in to my Amazon account whenever I attempt to view my orders or returns. This pop-up indicates that it is a Firefox security issue rather than a Windows problem. This situation has only started occurring recently, and I would appreciate any assistance in resolving this matter. My Firefox version is 150.03. Thank you for your help.

I was on a website for Met Opera, buying tickets and suddenly a widget appeared on the lower left corner that says: Opt-Out Signal Honored. Not only did I Opt Out, but I no longer can navigate the website, and there is no visible way to cancel this. Please help. It does not appeaer on other web pages, or other browsers. What is this? I've tried locating it in settings, and settings does not have that privacy option checked. How can I remove it? thank you, Anne Marie Mascia

If a site is designed so that it breaks if trackers are blocked, why would I want to deal with such bad actor? In other words, don't the exceptions to tracker-blocking enable bad website behavior?

For the past 2 weeks now, every single time I search on Google on private browsing there would be a CAPTCHA. I tried troubleshoot mode but the same thing happened.
