Firefox Support Forum

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.

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.

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.

I am using a Linux based system for my Laptop but still need to access and edit some files from a OneDrive Cloud. Whenever I try to clean up my files I open them to see if they can be deleted which will open a session in a separate tab. The problem is when I close that tab Firefox seems to keep that session active which will render me unable to delete a file because OneDrive sees, that it is still opened. (See attached Screenshot) Is this a problem with Firefox not closing sessions properly when closing tabs?

I install the latest version of firefox 110.0.1 (64-bit) as snap on 22.10 (Kinetic Kudu) running on WSL-2

WSL version: 1.1.3.0 Kernel version: 5.15.90.1 WSLg version: 1.0.49 MSRDC version: 1.2.3770 Direct3D version: 1.608.2-61064218 DXCore version: 10.0.25131.1002-220531-1700.rs-onecore-base2-hyp Windows version: 10.0.22624.1391

While Firefox is running OK I'm seeing a number of error messages. I would appreciate any suggestions on how to fix/debug

data = passwords, history, bookmarks, session logins

the crash I got from last update, made me lose months of work.

I want to try to save as much I can by importing/exporting my data

I decided to change my OS, and before it, I clicked "Sync" in my Firefox account. When I installed another OS, I logged in my Firefox account. And... None of my data restored (bookmarks, passwords...). I did not make data export as a file because I trusted this deal to my Firefox account. How do I restore my data?

I have read multiple posts & articles about cannot reach ups.com website. Nothing others did works for me. I have re-installed Firefox, cleared caches, started in safe-mode, on & on ... etc. etc. etc.

For the last week, FIREFOX has been slowly deteriorating & cannot reach various business websites:

ups.com Hmm. We’re having trouble finding that site.

foodlion.com 504 Gateway Time-out Microsoft-Azure-Application-Gateway/v2

I have run software to find malware & viruses, with no solution.

I have NO TROUBLE using CHROME to access the same websites.

Who has the magic answer?

I want to stop Firefox from silently updating in the background during browsing sessions. When it finishes updating like this, currently open tabs stop working and I can no longer open new tabs. The only fix is to restart Firefox. This is a problem if I am, for instance, going through a set of web forms as the information I enter will then be deleted and I have to start again.

When I have used Firefox on Windows, the requirement to restart Firefox to install updates has always been indicated by some change to the settings button on the top right of the window. With Ubuntu, the update is downloaded and installed without any action from my part, and given that it is quite disruptive this is unacceptable.

I have tried a number of ways of changing this, none of which work. Under the general settings tab, there are no options for changing the way updates are handled. Settings under about:config appear to do nothing. I have app.update.auto set to false, and app.update.notifyDuringDownload is set to true. I have attempted to circumvent these by setting a policy using the policies.json:

{

 "policies": {
   "DisableAppUpdate": true,
   "AppAutoUpdate": false,
   "BackgroundAppUpdate": false
 }

}

None of these have made the slightest change to how Firefox handles updates.

I am running Firefox 110.0.1 (64 bit) on Ubuntu 20.04.5 LTS, but I should point out that this has been a problem for the last several years of Firefox versions on the same OS.

Hi.

Firefox is very slow. If i do the same browsing, in Chrome, there is no problems.

Reinstall Firefox, and all the guides, is tested - no luck.

I really love Firefox, and have used it, for many years, but this slow experience - that will scare me away.

A drug company website that I have used for a long time now gives me a message at log-in that it is "unavailable. Please try again". I have contacted the company and they say their website is up and running and that I should use another browser. I did try to use the Chromium web browser and was able to sign on with no problem. So, I surmise there is something wrong on the Firefox side. Is there a fix for this?

Crash report submitted bp-37f84164-6125-4ae1-9e55-8a8200230225. Started happening about once a day over last few days possibly since 110 FF update (Ub kernel was also updated a few days back) Have to do a hard power off & restart
