Firefox Support Forum

I've been using multi-account containers for a few months now, and loving it. I use the no-container firefox for work, since clicking on links in other apps goes straight there. So I have a personal container, financial container, shopping, and media.

The problem usually occurs with financial sites, that have a lot of redirects in their login page. For my privacy, I won't list which ones, but they are major financial institutions with fairly "slick" web pages (slick as in very annoying and overly complicated...).

Even setting "always open in container tab" doesn't seem to do the trick. I get stuck in a loop where the login page fires, then it seems to "break out" of the container tab, before redirecting back to the login page. The tab color goes from green to regular grey and back to green. Any ideas on how to fix this? On some pages I'm able to set the "always open in container tab" option on the intermediate pages, but others I cannot. Seems like when the login goes through a proxy or something I can't make it work. Any ideas?

Dear Team,

We would require some clarification or support for the below issue encountered while running JAWS on different browsers

Problem Statement: Popup Content not read in FireFox Browser

• JAWS screen reader (version 2022) works intermittently on FIREFOX version 98.0.2 ( 64-bit), i.e. Sometimes it reads the content from the popup screen and after a couple of attempts it doesn't read the content at all.

• JAWS reader works properly with Chrome and Edge browser.

Request you to kindly guide us on getting the required support for the above mentioned issue. Are there any limitations or issues encountered in JAWS Screen reader tool.

I'd like to open specific site pages in a specific container and also allow other than those specific site pages to open in any container. Assigning containers by deep-link or :[port] would help with web dev and content authoring. e.g.:

WordPress sites:

• Bulleted list itemwordpress.example.com/wp-admin/* pages open in my assigned container
• Bulleted list itemwordpress.example.com pages other than /wp-admin/ open in any container (without the "Open this site in your assigned Container?" warning).

This helps me to see updates as an unauthenticated user or as another authorized user assigned another role.

Thanks for your time and assistance. Please let me know if more info from me helps responding to this question.

Hi, how do we set Firefox 99 to use the os/system print dialog?

We are using Linux.

In Firefox 97/98 we could change these settings in about:config: widget.use-xdg-desktop-portal.file-picker = 1 widget.use-xdg-desktop-portal.mime-handler = 1 widget.use-xdg-desktop-portal.print = 1 widget.use-xdg-desktop-portal.settings = 1

Then we could get the os/system print dialog by clicking the "Print using the system dialog..." in the Firefox print preview.

In Firefox 99, widget.use-xdg-desktop-portal.print is gone. No matter what we set the other widget.use-xdg-desktop-portal.* keys to, we can only get the Firefox print dialog, when clicking the "Print using the system dialog..." in the Firefox print preview. We do not get the os/system print dialog.

So, how is that done now?

Thanks for your time :o)

I am running into a issue that's been plaguing for months now. After erasing some of the default multi-account containers on one my sync'd computers I am now dealing with, seemingly random container multiplication that I don't know how to make them stop.

As soon as this issue appears on one of my computers that issue propagates to the the other computers that are sync'd

Hi,

I have issues clearing "Save to PDF" from FireFox from the print preview. My company uses Firefox ESR for our Linux workstations.

I updated the about:config to disable the print options and still no luck. I even set the ~/.mozilla/firefox/*.default/prefs.js to following:

lockPref("print.save_as_pdf.internal_destinations.enable", false); lockPref("print.save_as_pdf.links.enabled", false); lockPref("print.save_print_settings", false);

I removed print_printer which had Mozilla Save to PDF

Nothing seems to remove the "Save to PDF". A liability for my company. Even went to about:support and clicked on "Clear saved Print Settings" and still nothing.

Any suggestions?

I use google-chrome with the --app option extensively in scripts on my Linux systems. Does Firefox has such a similar option?

As a basic example: /opt/google/chrome/google-chrome --app=https://docs.google.com/

Thanks

When viewing a WikiSpecies page with many displayed links (e. g., https://species.wikimedia.org/wiki/Cymindidina), clicking an unopened (light-colored) link opens it to a new page and turns the link color to a dark blue. This display is controlled by the choice "Never" on the Firefox "Settings/Colors" page. The colors of links seem predetermined by "Never", which also enables unused links to be shown red.

Is there any way to change the clicked-on link color from a fairly dark blue to a darker one, while still showing unused, empty links as red?

My eyesight is not the best, and a darker blue "Never", if possible, would help me be sure I had visited a page.

Hi,

I used Firefox ESR on an old version of Puppy Linux (Slackware-based). It worked fine until about the end of November 2021, after which none of the updates worked. The last working version is 78.15.0esr (32-bit).

On any later version, if I run Firefox from a console I get the following error message:

firefox: symbol lookup error: /opt/firefox/libxul.so: undefined symbol: gdk_screen_get_monitor_scale_factor

About the same time this happened, Tor browser (based on Firefox ESR) also stopped working, giving a similar error message.

Could anyone explain to me why this happens and if/how I might be able to fix it?

Thanks.

I was wondering if some websites ask for my microhpone permission, it can autofocus to the microhpone permission dialog of Firefox.

Because I sometimes use the Tab key to browse the websites, when the websites ask, I have to: 1. Press Tab key to several times to first get to the Firefox Menu Bar. 2. Press directional key to choose the phone icon. 3. Press Enter key to enter in the permission dialog.

Thank you.

Fix it so the FireFox browser Version 88.0 for Ubuntu (Linux) works AGAIN at saving website Login data using a Primary password via your 'FireFox Sync' advertisement (documentation).

Firefox is unable to load module

I've been trying to setup a smartcard reading device, and I've gotten stuck twice on the same place.

When it comes to configuring the Security Device on Firefox, I can't access the .so file. Firefox merely shows the error "Alert: Unable to add module", but I've noticed that when I try to browse my files manually, trying to access the /usr directory returns an error (sometimes, I seem to not be able to get it consistently).

It also happens that the software I installed for the digital certificate tried to open an html with Firefox, which is located in /usr/share/, and Firefox doesn't seem to be able to load that either. It returns a "Can't open file".

Steps followed

1. Open Firefox
2. Settings → Privacy and Security → Security Devices → Load
3. Insert path /usr/lib/libpkcs11-dnie.so and try to load (yes, I've checked that the file does actually exist)
4. Receive Alert: Unable to add module error

Relevant information

   Ubuntu 22.04
   I'm on the latest snap version of Firefox: 100.0.1-1
   Trying to setup the digital certificate for my Spanish ID (DNIe)

like in [https://support.mozilla.org/en-US/que.../1358775|this] this article. I see stranger accounts in my browser saved session suggestions. I only use my ff account in my personal computers and i'm not share my computer with strangers & guests. (this does not mean no one used after i leaved a computer with resetting that computer). Rarely using my personal computer(s) in public networks.

Do you have any ideas why this is happening and how can i prevent ?

putty was working fine until i recently upgraded the system to 22.04 LTS.my final requirement is to launch putty from firefox page using telnet://x.x.x.x:1234. using the firefox application handler /usr/bin/putty. i have already set the handler, but its not launching. The putty version is 64-bit Unix (GTK + X11)

Hi,

If I launch this, all's fine:

firefox.exe http://myurl

I can view the site at http://myurl.

However, I want to launch firefox with a specific profile, so I tried this:

firefox.exe -profile "C:\firefox\profile" http://myurl

I know that the profile's directory is loaded and written to because I created that dir with ONLY chrome/userchrome.css, and after launching firefox I can see a whole bunch of new files in there (eg. json files, sqlite files, etc.)

I can also see that it is also properly applying the settings in userchrome.css after I enabled toolkit.legacyUserProfileCustomizations.stylesheets.

However, http://myurl is not being opened at all. The culprit seems to be my userchrome.css which contains:

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

1. openLocation, #urlbar-container, #CustomizeToolbarWindow, #toolbar-context-menu, #menubar-items {

display:none!important;

}

My intention is to open a URL and disable all other bells and whistles in the browser except the window and forward/back buttons (ie. I do not want kiosk mode).

How can I do that?

[EDIT]

It seems that #urlbar-container is the problem. If I set it to display:none!important, firefox will not open the URL I provide on the command line. Why? So, how can I tell firefox to open a URL but not allow the user to navigate elsewhere by typing it in the "urlbar"?

[EDIT 2]

This seems to do the trick:

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

1. openLocation, #CustomizeToolbarWindow, #toolbar-context-menu,
2. search-container, #personal-bookmarks, #menubar-items {

display:none!important;

}

1. urlbar-container {

visibility:hidden;

}

However, I'd like to know if there are caveats.

BTW if Mozilla's support for userchrome.css will ever be dropped in the future what is a better way of doing the above? I certainly can't use kiosk mode and -app (app mode) is unavailable and will probably never will be.

I was using a Private Browsing window. I logged into an account and when I finished, I closed the window. I still had a standard FF window open. I realized I hadn't finished my transaction with the account that I had logged into in the private window a minute earlier and opened a new private window. When I went back to the site for the account, I was already logged in. I was surprised by this. I thought that all the information in a private browsing session was gone once that window was closed. I'm not the only person that thinks this. https://support.mozilla.org/en-US/questions/1295042 https://support.mozilla.org/en-US/questions/1305020

The answers to those questions are old. Has the practice of needing to close ALL FF windows after finishing a private browsing session gone away or that of using the Storage Inspector to delete cookies been replaced by a more convenient solution?

It seems to me that if those answers are still standard practice that those practices should be communicated to FF users in a more obvious way in the name of privacy. The practices required in those answers seriously diminish the effect of privacy in private browsing for unknowing users. And they're inconvenient for those that know.

I'd like to use Vimium on every page. Some Firefox pages disable add-ons, like the settings page, when viewing pdfs, home page, this page etc..

How do I keep Vimium enabled always?

On these pages, clicking the Vimium icon reads: > Vimium is not running on this page.

> Your browser does not run web extensions like Vimium on certain pages, > usually for security reasons.

> Unless your browser's developers change their policy, then unfortunately > it is not possible to make Vimium (or any other web extension, for that > matter) work on this page.

Note, I originally had this thread but it got archived. What I said works, no longer works, probably after an update: https://support.mozilla.org/en-US/questions/1339503
