Firefox Support Forum

Hi, i am on linux an Firefox 115.0.2. Every supported website appeared in dark mode because of my preferences in the firefox settings respectively about:config layout.css.prefers-color-scheme.content-override is set to 2 and my system mode is dark. (0 and 3 changes nothing) Since some time this settings does not work anymore. The only thing i have changed is: about:config - privacy.trackingprotection.enabled set to true So now all the websites appeared in dark mode now appear in light mode. Chrome shows all these websites in dark mode. (But of course thats no option :-)) An Example: reddit.com: before: dark, now: light mode, Chrome dark mode. So please help! regards, awilli

hi, something happened to my themes. i can no longer see the preview/thumbnail of them, also the authors link is gone. i've been trying everything for hours, but couldn't find anything in about:config that worked. any help would be great, thanks!

This issue is so annoying, that I need to ask Firefox community what I can do. So, the problem is, that if I set custom home page called Infinity New Tab (Pro), then I will restart Firefox, then it reverts back to Firefox Home.

I think, that this is completely unrelated to malware, because I'm scanning my computer very often.

Are my preferences/settings corrupted?

However the Infinity New Tab (Pro) is no longer available in addons.mozilla.org, so if you need .xpi file, then tell me, and I will attach that file here.

Is it possible to permanently set a different search engine for private browsing? I have Google set as my search engine in my normal browsing mode, but I'd like the private browser search engine to be permanently set to DuckDuckGo.

(I realise I can manually set it each time to DuckDuckGo but this is tedious.)

With thanks.

The only icons I can see on the right hand side of my toolbar is the NoScript icon, along with the Save to Pocket, FF Account, Extensions and hamburger buttons.

I should have about 12.

I just installed a new system, launched FF and set it up to sync with my account. Everything else appears to run fine - passwords, history, etc. The Tree Style Tab works fine too.

I have double checked the other solutions I found here, such as private viewing options, or trying to find the icons in the customize screen, but that's not the issue.

My other FF instances on other machines are still fine.

I just updated FF on this problem machine to 115.0.2 but no joy.

My firefox installation always run in English with all of its interface elements being in English. One of the recent updates introduced a weird behavior - some of the UI became Russian. I seem to have fixed/bypassed the issue last time it happened https://support.mozilla.org/en-US/questions/1415337 but nothing works this time.

Most of my firefox is in English, but some elements such as tab titles in devtools, browser popups "do you want to leave this page", tooltips in this very text form where I'm typing right now - are in Russian for no apparent reason.

I have another profile on this firefox installation and it's completely in English as intended. I tried to check for what changed in about:config, looking for "language" or "locale" string, and there's nothing that stands out. I've tried clearing startup cache, switching language back and forth, restarting firefox.

Any suggestions?

Any extensions I install suddenly don't show up in my toolbar or the customization menu anymore, so I also can't drag them there manually.

Deleting the extensions and re-installing them didn't work, neither did deleting the extensions folder itself.

Does anyone know how I can fix this? I've attached a screenshot of the customization menu and extensions menu below.

Thanks :)

I asked a few "security/privacy" addon creators this question: "

Hail all:

First off, a note to explain this post: I have severe Asperger's and ADHD. I work for a Corporation that handles delicate data. Now, my Asperger's requires clarity, but this ad-on is all BUT clear. Which is a serious annoyance, since, more and more, life is becoming unclear, due to continuous contradictions everywhere. More so ... it, at first glance, appears to be not quite right: The ad-on promises security and privacy, BUUUUUT ... does seemingly the absolute opposite? Let me explain:

So, I got the Multi-Account Container ad-on. Upon installing it, it requested:

   Access your data for all web sites
   Access browsing history
   Monitor extension usage and manage themes
   Access browser tabs

Why on earth are these needed? Now, you speak of privacy, security, all very nice, but then you throw these "necessities" in the ad-on, which totally counter the promised privacy, security and whatnot.

I have certain data that I access through the Private Window in Firefox, related to my work. Several tabs are Corporate Account information, log ins, ... , which I darn sure refuse to give out. Not to mention, Corporate project data.

Your "necessities" breach privacy, security, and even invoke the possibility of personal data theft, bank data theft, and even, indeed so, Corporate espionage!

1) Access data for all websites: Why not just ask the darn info directly? I will open the Corporation for you, give you all access keys. Way faster. 2) Access browsing history: If you need money, just ask ... I do not like my data shoved out for money so they can "offer targetted advertising". I HATE advertising, each ad I encounter brings my IQ down by 10 %, because my poor dumb brain can't understand the stream of lies in those. Also: you have no rights to dive into my history data, it is "private" for a reason, protected by LAW. This then breaches these Privacy Laws. 3) Monitor extension usage and manage themes: Oh? Am I per chance a COMPLETE idiot? That I can't read, or think? I am quite sure, I am just clever enough to handle this myself, I reckon. Could be wrong, but then there's google and the likes to help me out, in case I do not find the right colour and icon for my tab. 4) Access Browser Tabs: Here's a smarter idea, I think ... well, for as far as I CAN think, seeing the above uncalled for "assistance" provided: Come to my place and have my computer. Direct access thus no need to do all that network doing thingy needed for remote Browser Access.

Sorry for appearing angry, but these kinds of "necessities to ensure the ad-on to work". This ad-on can just as well work without these "kindly offered assist tools". So why are they in here, while you provide your ad-on as a means to secure and privatise my data?

I would appreciate some information here. Thank you."

I received no reply yet, though I asked 11 creators nigh 2 weeks ago. Seems ... fishy ... no? I mean, can someone give an explanation on this?

Thank you. Ben

The solution for the original Disable F11 (https://support.mozilla.org/en-US/questions/1255696) is no longer working. When the solution is executed from the Browser Console...

doc = Services.wm.getMostRecentWindow("navigator:browser").window.document; if(E=doc.getElementById('key_fullScreen')){E.removeAttribute('keycode');E.removeAttribute('command');}

The return is a reference to "HTLMDocument chrome://browser/content/browser.xhtml" which can be opened up and displays more information.

It used to just come back with something like "Undefined." and then it worked (F11 was disabled for the browser instance). Looks like it just started to not work with this latest version of 115.0 64-bit as this solution has been working for over a couple of years now.

Is there a way to enable this to work in the latest version?

My preferences are set so that "When you open a link, image or media in a new tab, switch to it immediately" is OFF. Therefore most of the time when I Cmd+click on a link, it opens on a new tab that loads in the background. This is what I want.

However, some websites break that behavior. 2 high-profile examples:

• In Google Docs, if a piece of text links to an URL, clicking on the text shows a small window with the URL. Cmd+click on that URL opens it in a new tab, and takes me to that tab.
• In Facebook Messenger, if I Cmd+click on a chat, again the chat opens in a new tab and I'm taken there. Additionally, the original tab activates that chat.

Interestingly, in both these cases, I get the right behavior if I right-click on the URL or in the chat and in the contextual menu choose "Open link in new window/tab/container tab": the new tab stays in the background.

So my question is: does anyone know of a way to always make cmd+click behave just like "Open link in new tab", no matter the website?

I'm on Firefox 115b4 on macOS, but this has been like this for years at least.
