Firefox Community 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.

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

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

I've been using Firefox for a few months now to follow online training courses or videos on the conversation papillon (www.conversationpapillon.com) and conversation santé (www.conversationsante.com) websites. For a few weeks now, the videos are no longer accessible on the pages of these two sites. The window of the video is empty. However, if I try the same link in Google Chrome, it works fine. I've contacted the publishers of these two sites, who tell me that nothing has changed on their sites in recent weeks. He advised me to contact you to find out more. Can you help me? I prefer to use Firefox, which protects my privacy better. Thanks in advance. Regards, Jean-Pierre R.

Hi! Since yesterday, in Outlook, my font size became very tiny for subjects and categories. I can barely see it. Can you please restore them to normal sizes?? I am desperate trying to read them. Thank you! Shirley Savva

When I open Firefox it's just a black page and anything I click on isn't responsive. I can't go into options or anything. Sometimes Firefox doesn't even load. It worked fine earlier than all of a sudden It stopped working today. Web pages don't load. Nothing works

I seen a post earlier that had a link to a supposed fix but I couldn't figure it out. So if anybody is able to help me it would be much appreciated. I am not an advanced user when it comes to Firefox

So, my browser is disabled. I can open it, but if I type anything in the adress bar (the home menu with recomendations and the search tab doesn't pop up) it will process the information, but then stop and gives me a blank screen. I send an image of it. For example if I type https://www.google.com the tab will go white and I can't do anything about it. In the apliccation menu, the only thing I can do is to go into troobleshooting mode by clicking the Help tab. Everything else (except for the new tab or window tool) is disabled. I beleive it is coused by the fact I can't open any website and those tabs are links. Please write back.

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.

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.

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?

I don't think "Tabs" is the right topic, but maybe it's the best of the choices since "Other" isn't an option.

I have an email with a link to a monthly newsletter, which should take me to February's issue. When I click on, or copy/paste, the link, I end up with the January issue. When I copy/paste in Chrome and Safari, I get the February issue. The newsletter people suggested clearing my cache/cookies in Firefox, but that didn't help. No matter how I try to navigate to the newsletter in Firefox, I get to January. I have tried everything I can think of, and still get the January issue in Firefox, while that same link gets me the February issue in Safari and Chrome.

I'm using Firefox 122.0.1, on a MacBook Pro (Sonoma 14.2.1).

I'd appreciate any ideas you might have!
