Форум поддержки Firefox

There are multiple screenshots attached below, 2 of them showing setting marked in red. Those settings are pre-configured with the firefox.cfg file. I would like to also pre-configure a list of other settings. You can also find those other settings below.

Anyways, i remember someone from this forum told me there is no "official documentation" for the firefox settings which are listed in about:config. Is there an "inofficial documentation"? If you could reply with the exact setting that i have to change according to the screenshot attached below that would be awesome, otherwise an URL for some sort of documentation would be welcome..

Basically all the setting i want to change exists and can be manually edited using the firefox settings, but theoretically could be easily pre-configured with the firefox.cfg.

All i need are setting-names/ids.

Is there a preference in about:config to fake or simply block websites from reading the font-list of my operatingsystem? I think it is pretty ridiculous anyways that websites can access this information since it has nothing todo with the webbrowser visiting the site but going beyond to spy on information that i consider private.

Same question goes for audio-readout, is there a pref to fake or block?

On this site: https://www.orange.pl/twojekonto/zaloguj I can't force firefox to remember username (no problem with remembering password on next step). In older Firefox without WebEx there was addon which allowed to manipulate forms to prepare proper autocompletion data. This addon is not supported with WebEx anymore due to lack of proper functions. Instead Firefox Dev Team claims that mechanism built in current Firefox is enough for such tasks and mentioned addons are not needed. Seems it is wrong thinking.

I tried different approaches to save username for mentioned site but without success.

For example when i download Tor they share a PGP KEY to verify the integrity of the downloaded exe. Other websites share for exmaple sha 1 or sha256 or md5.

However i cannot find any such option for firefox browser. Am i blind or it doesn't exist? Then how am i supposed to be 100% sure that my downloaded exe has not been modified by someone like my ISP, Government, Criminals/Hackers?

When I want a URL, I type it in the address bar. Search has no relevance to a URL, and any intervention of Search gets in the way, and creates errors.

When I click in the search bar, it's because I want a keyword search with one of the search engines. A search is not a URL.

They are two completely different things, and treating either one as the other is error. I do not want Firefox to kidnap my cursor and teleport it to somewhere I didn't click. They are two entirely different spaces, they are not interchangeable. When I click in the search bar, it's because I want a search. Don't you dare second guess me and change my click to the address bar.

How do I turn off this stupid stupid stupid error behavior of FIrefox?

I tried this and it didn't work. In about:config • keyword.enabled and toggle it from True to False. • browser.fixup.alternate.enabled and toggle it from True to False.

On some websites, such as https://mapgenie.io/elden-ring/maps/the-lands-betweenm images appear as these diagonal lines. Opening these websites in other browsers doesn't present the same issue.

Hello,

I did some changes to the browser according to a privacy guide: https://restoreprivacy.com/firefox-privacy/

When I now watch a video, while the overlay is there, the over a third of the video height is full of green horizontal stripes.

I can't figure out which change to the browser leads to this.

Do you have any idea?

Regards, Robert

I dont care what you are going to say to make it sound okay, it is NOT OKAY AT ALL. Mozilla Firefox supposed to be a Privacy Browser is not making business with Meta -> Facebook, lately i really question the mental health of Mozilla, first a unique identifier, now a partnership with zucking facebook, what's next? Let me tell you something, if you are a privacy company then get the zuck away from companies who don't give a damn zuck about privacy -> facebook, mozilla can NOT simply make a deal with facebook and claim "oh dont worry it's ok your privacy is secure, bullsh!t.

You know what, i have been using Firefox since i first accessed the internet with a webbrowser, now hear this -> one more negative thing from mozilla and that's it, bye mozilla you have lost your way.

While this is only me speaking here, MANY people have already quit firefox because of what mozilla has been doing recently. Continue what you are doing now, and soon your greatest product -> firefox will be dead. When privacy partners with tracking & spyware this is the definition of suicidal behaviour. I really worry about Mozillas Mental Health lately.

I will copy paste this post to a few other mozilla releated forums, let's see how long it stays on before censorship happens.

Here a few comments from reddit users on this topic:

The article says what it says, but we all have a long memory of Facebook/ Rebranded Facebook being a company that is horrible, and not to be trusted when they put out a press release. -Nailed it

I’ve been using Firefox since like 2002. I never stopped. I really hope I don’t have to soon. I will give them the benefit of the doubt. -Nailed it

Facebook is one company you should keep away as far as possible. -Nailed it

Then read the article, and see that this is a case of Mozilla working with Meta to maintain privacy. -This person must have mental issues, time to see a doctor asap!

Possible bug: I cannot stop Firefox from restoring sessions after restarting computer. Restore previous session is not checked in Settings, browser.sessionstore.resuming_after_os_restart is false, and browser.sessionstore.resume_from_crash is false as well. Ubuntu 20.04, Firefox 91.0.2, only add-on is TreeStyleTabs, but this behavior displays with add-ons disabled.

while using any firefox addons for speeding up a video higher than 4.0 of original speed the video sound suddenly goes off by default. in other browsers such issue does not appear. only in firefox. what to do?

This is going to be long sorry. A lot has transpired

My son was using 78.15esr. I upgraded it to 91.3esr. After the upgrade the browser worked; tabs loaded, surfing was fine, could go into settings and about:config was fine.

He went to watch something on Netflix. Netflix complained his browser was not supported and he needed to upgrade to the latest version - which at the time was 91.3esr.

In frustration he installed Chrome. When he tried to run it he was told software restrictions were in place. I had not set any restrictions, and I checked secpol.msc and there were definitely no path rules defined. If restrictions can be set in group policy I had not set them because I am unaware of them.

So he installed Microsoft Edge, which installed VC runtime for 2013 and 2015-2019 for both x64 and x86.

At that point Firefox no longer loads tabs at all. About:<anything> doesn't work. Settings doesn't work. You can't go to safe mode (more on that later), and when closing the browser two processes remain taking about 60 seconds to end.

I did have the group policy templates for Firefox installed. When I upgraded to FF 91 I installed the latest templates.

A couple of times when I started FF it complained about vcruntime140 was missing. But just running FF again worked without doing anything else.

So I reverted to 78.15; I uninstalled v91.3esr. I deleted his profiles.ini and profiles folder and then copied them back from a back up. I removed any registry settings, and copied back the v78 ADML files. I then installed v78.15esr with internet disconnected. Did not run FF after install. Went into group policy editor and turned off telemetry and auto updates then re-enabled internet

Run FF and same issue. tabs not loading. Pages not loading. I can click on a menu and I can type into navbar and search bar but there is no response. I checked internet was working.

I deleted the %LOCALAPPDATA% cache folders. I flushed the DNS cache. None of this worked.

So I uninstalled FF again, deleted the profile folders and ini. Disconnected from Internet. Deleted any registry settings, and removed the group policy templates. Then installed 78.15 from scratch and let it create a new profile.

Same darn problem. It seems to me that installing chrome and/or edge has done something nasty, but I have no idea what. I say that because before he did that he could surf the web, but Netflix just said his browser ver was outdated.

I tried contacting netflix on chat but they were worse than useless.

So I uninstalled again and removed everything. Connected the internet and installed FF again and let it update automatically. Same problem.

I've left him with edge but I need to fix FF.

I even uninstalled the VCLibs, Chrome and Edge. These did not fix the problem.

I tried safe mode but when firefox restarts there are two processes that take 60+ seconds to end so FF sits there saying "restarting...". When those processes finally end Firefox does not restart.

Checked for viruses; nothing found. Rebooted PC several times.

So at this point in time; FF will run but will not load the 3 tabs; Facebook, Netflix and youtube. They stay blank. Settings is not accessable, nor is addon's or logins and passwords. Typing anything on the search bar does nothing Typing anything in the address bar does noting Trying about:config or about:profile or any other about's does nothing. When closing FF two processes take 60+ seconds to end.

If I go back to him and tell him I need to reinstall Windows he will go absolutely nuts.

What also worries me is that Netflix said that the most recent esr browser version was not supported and that he should update to a later version.

And what is even more troubling is I updated his girlfriends PC at the same time and hers works perfectly. This scares the hell out of me because I then expect responses like "Your sons problem is not a firefox problem".

I have an account on usps.com (the post office). Using FireFox, I am unable to see or use my address book on that site. USPS tech support says it's there and also says FireFox is the most problematic web browser of all. USPS tech support says to use ANYTHING but Firefox.

Yes, I have cleared my cache and cookies multiple times in an effort to solve the problem. And doing so does not solve the problem.

I can use IE or Chrome to access USPS.com and I can see my address book!

What the heck, Mozilla?

When video/audio starts playing on a browser, the tab title displays 'playing' text. This additional line resizes the window height and causes the tab content to resize too. For example youtube starts resizing video window height and width - and this is very annoying. How do I remove 'playing' text from tab FOREVER?

Firefox currently has a URL color formatting scheme which greys-out all parts of the URL in the address bar except for the top-level domain and the 2nd-level domain (with some exceptions).

I am building a website where my organization-specific domain is NOT located on the 2nd-level domain, but rather on the 3rd-level domain.

I plan to use the domain "obb.ll.land". The "ll.land" part is basically a domain that the Liberland Government operates and from which it sells 3rd-level domains to members of the public. Think of "ll.land" as a temporary ccTLD for Liberland. (ICANN requires countries to be on the ISO-3166 list—which Liberland is not yet on—in order to register an official Internet ccTLD.) Therefore, any domain that is formatted as "[SUBDOMAIN].ll.land" should be presumed to be the foundational domain for a given organization that uses it.

Therefore, when a client sees a Liberlandic website, the domain should have the 3rd-level domain included in the black-text portion of Firefox's URL color formatting scheme. Otherwise the scheme would be misleading about the true nature of the website involved. For example, the 3rd-level domain of "https://www.floating.ll.land/" should be included in the black-text portion. Same with the 3rd-level domain of "https://register.ll.land/". However, as of this writing, no ".ll.land" site has the appropriate URL coloration to my knowledge.

How can I solve this problem? Is there something which developers like me should add to our websites individually, or will Mozilla be responsible for handling this matter?

Thank you all in advance! :)

Hi, when I use Firefox on this machine, the bookmark sync doesn't work as expected. Instead of maintaining the order of the other devices' bookmark toolbar, it is ordering the non-folder bookmarks before the foldered bookmarks. How can I make it so the bookmark toolbar is the same across all devices? I have tried deleted places.sqlite and backupbookmarks folder.

OS: Debian 11

Thank you!

Hello,

I'm using Firefox 91.4.1esr (64-bit) from Debian repositories on Bullseye. Every time I open Firefox, a window with a greeting message appears ("Say hello to a new Firefox"), and it doesn't matter if, as asked by that window, I choose a theme or not. Is this issue related to my settings? Is this a Debian issue? Is it possible to stop that window from reappearing?

Thanks in advance. And many thanks for making Firefox (I've been using it for so many years I can't recall when I tried it for the first time).

It's still outputing, I can paste it out but the output font got glitched

We are seeing sec_error_bad_der error when trying to open a link with service certificate generated with x509.SHA256WithRSA signature algorithm. My question is, does FF support SHA256WithRSA?

I cannot use the PDF Viewer on Firefox 91.5.0esr (64-bit). Instead, I get an incessant popup asking what to do with the file. I've tried:

1. Selecting `Firefox` as the program to open the PDF. A new tab opens along with the popup.
2. Selecting `Firefox.exe`. Same deal
3. Modifying Preferences -> Applications -> "Portable Desktop Format ... (app or binary)" to Firefox. It won't let me - I can choose anything else or any other program, but choosing "Firefox" won't stick
4. Opening Firefox in "Troubleshoot Mode" (Help -> Troubleshoot Mode) then attempting all of the above. The setting still doesn't stick.
5. Disabling Hardware Acceleration, as one person cited that.

Every other thread has either cited changing the setting for PDF's to "Open in Firefox" or various names. Fear not, I've tried that, and am still at an impass. Any help beyond that is appreciated :)
