Firefox Support Forum

I'm stetting up a testing environment. It's a closed environment with no access to the Internet when it's in use.

The environment is launched from AWS and consists of an Ubuntu 18 desktop and a Ubuntu Server running Apache. The desktop is able to successfully load the website, but with a cert error that the certificate isn't trusted.

When the Ubuntu Desktop launches, it has a fresh install of Firefox, and therefore all the directories in the users home folder are not yet setup for Firefox, including the database where the root CAs are stored.

I'm am able to add the Root CA certificate into the Firefox cert database AFTER the machine fully boots and I run Firefox for the first time. I'm using the 'certutil' package to do this. After I load Firefox, then add the root CA certificate using certutil, I'm able to load the website without error.

I need to add this certificate to the database with the startup shell script for the machine.

Any help is greatly appreciated. Here's the commands I'm using:

1. copy the CA cert into firefox

export ffcerts=`ls /home/testuser/.mozilla/firefox/ | grep default-release` sudo certutil -A -n "testcert" -t "TC,," -i /home/testuser/certificates/testcertCA.pem -d sql:/home/testuser/.mozilla/firefox/$ffcerts

These commands work perfectly after Firefox is run for the first time. I've even tried adding 'Firefox' (with several different switches) into my startup script without success.

Hi, I disabled several options in About:Config, and a feature previously disappeared. When I pressed the scroll button in the diamond, it opened a tag and moved to it automatically. Whatever you do with the current tag, I want it. Please help me. ( I mean, it no longer applies to bookmarks, I want it to apply to bookmarks )

Hi everyone, I am currently using Firefox "112.0.1 (64-bit)" on Windows 10 "10.0.19045 Build 19045]"

I have problems using almost all Google websites: most of the times they do not load at first attempt, and when they do they do not works properly. As example: Youtube does not load (or the cached version says that there is no internet connection), then after a few attempts it loads but all thumbnails on the home are gray.

On another browser (Edge) all websites works normally.

Using private window has the same problem, I have no extension and no plugin other than OpenH264 Video Codec provided by Cisco Systems, Inc. and Widevine Content Decryption Module provided by Google Inc.. I tried emptying cache and also reinstalling Firefox.

The only fix I found on the web is to disable hardware acceleration from settings. If I disable it and restart the browser, then all websites works normally. Actually I can't see this as fix but as a workaround, since I am using a notebook and I'd like to use my GPU for video decoding and save energy.

Maybe I am missing something? Is there something I can do? Thanks.

The download is that I am always movies on the transfer to a good comedy and show us movies because of the news , e-mailed, browser Firefox Android.install and migrate etc

No matter what I try, I can't allow any sites to present my screen or a window, I can't find an option in settings neither in the option to allow in the tab. The "allow" button is simply not available at all. How do I solve that? The problem happens in all sites that I've tried: focusmate, cofocus, discord, google meet, etc

Hey, since 2 months firefox started crashing when a video comes to the end. I tried it in troubleshoot mode skipped to min 10:45/10:50 and played. after this 5 sec it just crashed. I noticed it on youtube but tried it on other players and it also happened. Today I also started a video on a other website and it crashed but not when starting youtube videos.

Here my last 5 crash reports: bp-8fdedc8b-c8bc-404f-9e3e-8f2fd0230813 bp-b15becdb-456b-4a22-971c-2c0c20230813 bp-9754361a-f67b-445a-9163-c88a20230813 bp-cffc46ae-9ae5-4678-a323-7b60b0230813 bp-a863679a-577e-45f4-9f4e-002bc0230810

Please enable the ability to use the "Dark Reader" add-on on this site or let us change it in the settings. Horrible experience in light mode. On the added image you can see that the "Dark Reader" add-on is enabled.

After the latest update (117.0 64-bit) I now do not see the '+' sign in the tab bar. I have 40 tabs open (please, no negativity - it's always worked for me), but if I close all of the tabs it reappears. Re-open the original 42 tabs and it's gone again. Close them and it reappears, etc. Now for the fun bit: starting from scratch with a new window - the '+' is there, but open 20 more tabs and it goes.

I use Iosevka font as my preferred custom font for websites, I really like this Firefox feature (actually one of the main reasons why I swapped from Chromium browsers), and as of updating my Firefox Nightly to "Nightly 119.0a1 (20230908094535)" version this feature no longer works on all websites, and only seems to work on the search bar when I open a new tab.

Image 1: Settings (unchanged since previous version when this feature worked) Image 2: Search bar in new tab is using Iosevka font correctly Image 3: An example of another website where the font is not being loaded where it did in the previous version.

Thanks.

Am I understanding this correctly?

HTML backup (bookmarks) doesn't support tags and annotations, but JSON backup does, and JSON backup doesn't preserve the website favicons, but HTML backup does?  

So, what I can do, is restore my (saved) bookmarks using JSON backup, then restore the HTML backup, this would get my tags and annotations, and the website favicons back? But the downside, I will need to remove duplicates?
