Форум поддержки Firefox

Hi, from many time (some months ago) I have this problem: sometimes (well, actually very often, but not always) when I start firefox it runs in “Private browsing” mode.

The problem happens both if I click on the icon in the gnome dock, and if I run firefox from the terminal. In both situations, the problem happens sometimes, and some times not.

When I launch it from the terminal, the output is the same, either if I see the bug or not.

The problem has already been reported on the Fedora support site, too.

What can I do to sort it out? Thank you very much

Running Firefox 108.0.1 on Fedora 36

My corporate network is being hammered by connections to firefox-settings-attachments.cdn.mozilla.net.

When looking at the squid logs, I see the following: access.log:1678216931.488 170104 1.2.3.155 TCP_TUNNEL/200 11400353 CONNECT firefox-settings-attachments.cdn.mozilla.net:443 - CARP/1.2.2.11 -

If I understand correctly, this connection is to download new files that pertain to security, cert revocation lists, blocklists, plus a bunch of non-security related stuff.

The question is, how do I make this file downloaded as small as possible while still keeping the security bits... (saw this page, and followed what I thought pertinent https://support.mozilla.org/en-US/kb/how-stop-firefox-making-automatic-connections) The second question is... can we change the download schedule of these downloads?

If you are asking why I am having network issues over 11 Mb, the answer is that all my clients go through a corporate proxy... We have many thousand devices and last time we choked the network with 80GB downloaded on a timeframe of 15 min.

Thanks much!

If I close developer tools while execution is paused, from F8 or by hitting a breakpoint, I can't find a way to resume the execution (with F8, F9, or by re-opening developer tools). Additionally the Threads section on the right is missing. Is there a way to resume the main thread?

After the version 110 update, Firefox has issues displaying text in certain pages like Google Calc, PDF forms, online publication readers. The text seems to break up and fade out. Navigating up and down the page often restores the missing text, but not all of it. Suck pages render without issue in Google Chrome. I am using Firefox in a Linux container within ChromeOS (stable channel), but this issue only started after the latest Firefox update.

It appears that the Firefox v. 111 update has solved this issue.

I need to Firefox to behave like SPIN Safe Browser, aka removing all kind of potentially unsafe material. Since Spin Safe Browser is built-in with NSFW filtering but it's only available for Android/iPhone, and no, emulating Android or iOS is NOT an option. None of the current desktop browsers met the criteria for me to be safe enough to block NSFW (porn) content on default settings, only SPIN Safe Browser can do this and it's not available for PC/Windows, or Linux for that matter, so my best bet is to configure Firefox as much as possible so it can block as much unsafe content as possible but there are two or three problems I am facing right now which aren't exactly easy to fix:

1. Troubleshoot Mode DISABLES all addons, meaning that if I restart Firefox on this mode, I will be able to search and view for NSFW material. There could be a relatively easy way to fix this by building Firefox from source without this specific option. If this is possible then all I need are to instructions on how to build it without Troubleshooting Mode. Doing this step is critical as Troubleshoot Mode is more or less the equivalent of "Turn the filter off, I want to watch porn", as it disables every customization made to enforce web filtering. See image 1.

2. The addons themselves can be removed, either by manually disabling or uninstalling them. This is a huge problem because once this is done, Firefox no longer is capable of filtering unsafe content by itself. I need that these addons cannot be removed, or as a workaround, add as many layers of difficulty to prevent this from happening or making it as difficult as possible so the user simply gives up because it's too complicated. Or, building Firefox from source with these addons by default would solve this issue. You don't have to install ALL the addons for this step, just a few of them will do the work. See image 2.

3. Additionally, if there could be a way to permanently enable DoH and set a specific DNS by default and prevent it from being disabled or changed to something else. For example: https://family.adguard-dns.com/dns-query could potentially help me achieve the result I want. See image 3.

Please note that SPIN Safe Browser always blocks NSFW content by default and it's impossible to search this type of content with this browser, there is no way to turn off the filter and this is exactly how I want Firefox to behave. I have read something about converting APKs into PWAs but I'm not really versed in that, but if you know a way to "port" SPIN Safe Browser to PC/Windows/Linux please let me know, or if you have any other suggestion than can help me make Firefox behave more like SPIN Safe Browser on it's default settings I would really appreciate that.

The issue I am facing, and for which I direct my question to all you intelligent beings, is that my network is being hammered by connections to firefox-settings-attachments.cdn.mozilla.net.

When looking at the squid logs, I see the following: access.log:1678216931.488 170104 1.2.3.155 TCP_TUNNEL/200 11400353 CONNECT firefox-settings-attachments.cdn.mozilla.net:443 - CARP/1.2.2.11 -

If I understand correctly, this connection is to download new files that pertain to security, cert revocation lists, blocklists, plus a bunch of non-security related stuff.

The question is, how do I make this file downloaded as small as possible while still keeping the security bits... (saw this page, and followed what I thought pertinent https://support.mozilla.org/en-US/kb/how-stop-firefox-making-automatic-connections) The second question is... can we do a scheduled window to perform these downloads?

If you are asking why I am having network issues over 11 Mb, the answer is that all my clients go through a corporate proxy... We have many thousand devices and last time we choked the network with 80GB downloaded on a timeframe of 15 min.

Thanks much!

Hello,

I've changed the background color on the private tabs/windows with this CSS:

@-moz-document url(about:privatebrowsing){
 html.private{
  background-color: #2B2A33 !important;
  --in-content-page-color: gray !important;
}

I would like to make the "background-color" to be the same as the window background without hardcoding it, so it always match the theme, ie:

 background-color: <window.background> !important;

I would like to do the same with the background color of the search box in the private mode window, but I can't find the id.

Regards.

When viewing certain websites while "Allow pages to choose their own fonts, instead of your selections above" is on (screenshot 1) most of the text is extremely pale to the point of being unreadable (screenshot 2). I've opened an issue (https://github.com/broadinstitute/gatk/issues/8115) for one of such websites in the past before realizing that it seems to be a Firefox problem. I realized that unchecking the option fixes the font color issue (screenshot 3). But in many cases it introduces a new problem where many of the buttons and interactive elements have this weird text rendered on top of them (screenshot 3). This happens for example in Google calendar. https://data.humancellatlas.org/explore/projects is another example.

So in the end neither of the options results in a readable web page.

Any tips on how to go about fixing it?

Summary : UI Freeze issue in Firefox version greater than 100 Behaviour: Screen becomes unresponsive We have an angular 13 web application running in kiosk mode in Firefox using command This UI unresponsive when no interaction with the screen for long hrs and sometime it is crashing while it is getting used. We are seeing this issue in all the Firefox versions deployed in our systems that are all version 100 or above. We do not see this issue in the same base device OS and resources with version 100 and below.System Details : Ubuntu 18.04.4 LTS, aarch64 GNU/Linux Hardware: Jetson Xavier NX RAM : 8 GB CPU : 6 cores  The way we solve this issue today is by relaunching Firefox. Just by closing and opening the browser makes the UI is responsive again.

Hi: I'm trying to find some way of removing the vertical lines in replies. A previous asking of this same question lead me to attempt to install the 'replywithheader' add-on but it hangs with the "Add ReplyWithHeader? This extension will have permission to: .... Cancel Add" popup box ... It doesn't matter if I click either Cancel or Add, the box just hangs there. Or is there some other way of removing the vertical lines? One might have thought this would be an easily accessible option in the setup.

Thing is that I'm working on a rather long report with other people and we email changes back and forth but each time another vertical line is added. How to nuke ALL the vertical lines? How to stop them from being added in the first place?

Hi, Have been having issues with the google cdm widewine drm plugin for a wee while now but eventually found the solution to my specific case. The problem was firefox never managed to install the plugin, it just kept saying it was installing it but never did.

It tuns out that my opnsense router uses an IDS / IPS watchdog plugin called ZenArmor. Tuns out it was blocking the download url for the plugin from the following address

https://r3---sn-c5ioiv45c-5goe.gvt1.com

If I added the gvt1.com domain to it s exceptions list, firefox immediately downloaded and installed the plugin flawlessly.

Sharing is caring. Ta-ta!

When starting to type an email address in a login box on, e.g., amazon, Firefox produces a drop-down list of suggested completions using common email domains such as gmail.com and yahoo.com. I never use any of these and want to either suppress the suggestions entirely or customise the list to display domains which I actually use.

Hi everybody,

I would like to create new firefox profiles which are preloaded with extensions of my choosing. This is for my own personal use - I am not an enterprise user. My OS is NixOS / linux.

I followed part of https://support.mozilla.org/en-US/kb/deploying-firefox-with-extensions where

• Created a folder (/tmp/ff)
• Created an "extensions" folder within that (/tmp/ff/extensions)
• Downloaded uBlock Origin into the "extensions folder
• Renamed .xpi to the "$id.xpi" (/tmp/ff/extensions/uBlock0@raymondhill.net.xpi)
• Started firefox (firefox --no-remote --profile /tmp/ff/)

Unfortunately, I was asked whether I wanted to accept the installation of the extension (see image), but I would like the extension to be active when opening the new profile. One can easily see that were I to add 10 extensions, it would be a nuisance to click through the list of extensions and activate them every time I created a new profile.

Hence my question: how can one create profiles with active extensions?

My FF updated to 110.0.1 (64-bit) on Ubuntu and several things which use to work really well are now broken.

For example, when making a new account, the password manager pops up asking if you want to save the username/password, but if you mouse over to that popup then as soon as you enter it it just disappears. When logging in somewhere, if there are multiple choices for userid (say with different dates) none can be chosen. You mouse down to the popup with the choices and there's a weird stroboscopic action where the popup disappears and is recreated as fast as it can, over and over, and nothing can actually be clicked on. If you type in the userid then try to enter the password the same thing happens. It's not possible to use the password manager anymore, both fields need to be typed in manually.

Another example is the search field. If you type something and there are several options from previous searches, and you try to mouse down to pick one, the popup disappears. If you click the search keyword again it highlights as for replacement, then you have to click it again (removing highlight) and only then can you mouse down and choose a search engine.

etc etc etc! All this stuff worked great until the upgrade happened (in the background) and now many things are a huge pain in the ass. Arrgh!

I tried disabling all add-ons then restarted but made no difference. Password manager is unusable.

We have control-L to jump to the address area, but how can I jump back to the content area, where the actual web page is?

I know I can hit TAB x amount of times, but I need a direct keyboard shortcut.

Firefox 110.0 64 bit on Linux Fedora 37. Happens with my default setup and also when running with extensions disabled. Default font. English Language.

If I got to this website https://www.endesaclientes.pt/uPortal2/MyEndesa/index.html#/login, right now, it is in maintenance mode. It's tab label shows up as "Em manutenção..." when it should display "Em manutenção". In case this text field munges my text, see image of the tab, and the letters between "uten" and the final "o" are supposed to be a c with a cedilla and an a with a tilde.

Do I need to change my configuration to add the proper font in tabs?

Hello. I just set up a self hosted firefox-syncserver on my homeserver.

I created a virtual host on nginx which looks something like this: firefox-syncserver.mydomain.com and have a mariadb database as the backend. In about:config on firefox, I then set the identity.sync.tokenserver.uri to https://firefox-syncserver.mydomain.com/1.0/sync/1.5.

Everything seems to work fine, but I still have some questions which I did not find an answer to online.

   Since I have this public accesspoint for my syncserver now, can not anyone just use it? What stops them from using my url (https://firefox-syncserver.mydomain.com/1.0/sync/1.5) in their about:config?

   What is the SYNC_MASTER_SECRET for which I set to a 256-bit random key?

   When I navigate to https://firefox-syncserver.mydomain.com/1.0/sync/1.5 in my browser, why does it say {"status":"error","errors":[{"location":"body","name":"","description":"Unauthorized"}]}

I would really appreciate a good answer, as I could not find anything good about these points online.

Hello,

I've just upgraded and almost done with the userchrome customizations but I need help with some little things.

Is there a way to remove the dotted frame in the history/bookmarks tree as seen in the attached picture.

Thanks.
