Firefox Support Forum

I inadvertently “signed out” one of my devices so now I cannot see it in my connected services lists. When you sign out a device it states that you will no longer be able to sync or see the device. How do I correct this action so that I can see the device again?

A few of my extensions are not showing up in my toolbar at the left top of the window -- specifically, my Evernote extension. It is turned ON in my "Settings" area, but not showing up in the toolbar.

This is a Mac Studio, 2022.

I also have two other Macbook Pros. The extensions show up on my Firefox browsers there.

Thank you Polly

Everything that has an active state seems to have suddenly gained huge thick borders, usually grey or black. This applies to UI and page elements. I have no idea what happened, I'm guessing an update changed 'something', but how do I nondestructively fix it?

All webpages seem affected.

(reddish bars in second screenshot are my removing some URLs, but everything else is my UI as seen)

Thanks greatly for any insights...

Hi there,

I am the product manager of a browser extension on your store

Our former CTO has lost access to the store a while ago (we no longer find the two-steps authentification device and we have lost the backup codes as well), which means that we can no longer update our browser extension because we can no longer login as the admins of that product.

I know that you indicate in your documentation - see screenshot - that you cannot help if we no longer have the backup codes. But I prefer to contact you anyway because we are currently blocked and can no longer manage our own product.

Please, would it be possible to get in touch with me and indicate the next steps recommended to us?

Best wishes,

Anthony

I have never had trouble with Mozilla before, it's been fantastic, but since I downloaded the newest version, 111.0, I am able to download any normal website, but when I try to open one of my streaming services I can log in but Firefox won't load the pages fully and won't load the videos at all.

All sites work perfectly on Chrome and Edge, but I really don't want to use either if I don't have to.

Thanks

The interface fonts in my firefox are impossibly tiny

Specifically where it is an issue is when I go to bookmark a page - the menu interface is in TINY font and despite totally resetting firefox and creating a brand new profile etc etc

I have NOT been able to change it - I am at my wits end

I attach a screen shot to show you It also happens on the firefox home screen with frequently visited sites

PLEASE help me

Hi,

I am trying to setup firefox to my liking automatically To this end, I am using "firefox profile maker" and it works great but I'm having issues adding all the add-ons that I like.

Only the add-ons that are included in ffprofile make seem to install properly (but also, now I can't uninstall them ??)

Anyway here is my full process for installing firefox automatically and then configuring it automatically. Perhaps you can hep me figure it out.

First I install firefox automatically using the offline installer (my computers do not have access to internet by default, I must whitelist each computer, then individual software then individual websites first)

So, I obtain the offline installer from this URL https://download-installer.cdn.mozilla.net/pub/firefox/releases/111.0/win64/en-CA/Firefox%20Setup%20111.0.exe

Next I have used the website https://ffprofile.com/ to create a pre-made profile

This yields two files, and their contents profile.zip

profile\prefs.js profile\extensions\CanvasBlocker@kkapsner.de.xpi profile\extensions\uBlock0@raymondhill.net.xpi enterprise_policy.zip defaults\pref\autoconfig.js distribution\policies.json firefox.cfg

Next, I have pre-downloaded added all the add-on files I would like to install to the add-on folder However, when I perform the procedure, only canvas blocker and uBlock0 get installed

I'm not sure what I'm doing wrong. If I take all the add-on files, dump them all into firefox, it opens 16 tabs On each tab I can now click add and click okay, if I do it right and quick enough, they all install, unless I miss one.

That's over 50 clicks and very annoying !

Here is the list of add-ons I'm trying to add

extensions\umibo-2.4.2.xpi extensions\amp2html-2.1.0.xpi extensions\close_tabs_right-1.2.4.xpi extensions\cookie_autodelete-3.8.2.xpi extensions\copy_tabs-1.12.35.xpi extensions\darkreader-4.9.62.xpi extensions\facebook_container-2.3.9.xpi extensions\google_container-1.5.4.xpi extensions\istilldontcareaboutcookies-1.1.1.xpi extensions\merge_window-1.0.2.xpi extensions\old_reddit_redirect-1.6.1.xpi extensions\order_tabs_by_domain-0.2.3.xpi extensions\privacy_badger17-2023.1.31.xpi extensions\spoof_geolocation-0.1.1.xpi extensions\tab_manager_plus_for_firefox-5.2.0.xpi extensions\traduzir_paginas_web-9.6.1.xpi

I have created a script that I run after installing firefox using this command

"Firefox Setup 111.0.exe" /S

Then I run the following script to automatically install my pre-made profile

Firefox-deploy-ffprofile.bat

@echo off set z7EXE=%PROGRAMFILES%\7-Zip\7z.exe set EnterpriseConfig=firefox-profile\enterprise_policy.zip set ProfileConfig=firefox-profile\profile.zip set FirefoxProfile= set FirefoxInstallFolder=%PROGRAMFILES%\Mozilla Firefox\ set FirefoxProfilesFolder=%APPDATA%\Mozilla\Firefox\Profiles\

tasklist /nh /fi "imagename eq firefox.exe" | find /i "firefox.exe" > nul if %errorlevel% equ 0 (echo Firefox is still running & taskkill /f /im firefox.exe & timeout /t 5 )

end

echo firefox deployment finished

I wish this process was not so onerous as it has consumed my entire monday :( Thanks

I'm attempting to print to my printer, a document from Google Doc but each time I select or hotkey the print function it prompts to download the page to PDF instead.

• Bulleted list item Sporadically it will print on some random sites, others it prompts to download PDF
• Bulleted list item My printer is setup correctly and set to default
• Bulleted list item Printing to my printer works on and on PC document as well as Chrome, IE, Edge every time
• Bulleted list item I have used the 'Clear saved print settings' in the Help section
• Bulleted list item I have changed default PDF applications to Firefox and other programs
• Bulleted list item I have reset browser, refreshed tabs, power cycled printer

All of these changed nothing. Firefox printer settings are few and far between, I was surprised for a basic and important function.

Would appreciate any help thank you.

With Windows 10 autofill with Firefox never worked for me even though the appropriate options were checked. I recently upgraded to Windows 11 and it worked! So happy. But that was only for about 2 weeks. And then a couple of days ago it stopped working. (Maybe from a Firefox update??) It's really frustrating and tedious even with the passwords being filled automatically when I start the login process with the user name. Is there anything that can be done?

autofill for credit card not longer available. I had it for some time, but within the last week or two, it disappeared, and there is no longer an option under privacy/security settings in the browser.

I have a feeling I know the answer, but wanted to confirm. Due to unforeseen circumstances, I had to reset my PC. Upon doing that and downloading Firefox all of my data is gone. Bookmarks, saved logins, etc. all gone. I thought once I logged into my Firefox account everything would be there. I've logged into my account on other computers in the past and all my stuff was there but not this time. Now it's saying all of my stuff (profiles, etc) was created today. Is my stuff really gone forever? I thought the whole point of the Firefox account was so I could just login and have everything sync.

I have over 800 emails in my trash folder. Do they delete automatically every month? If not, how do I empty the folder? Also, when I take a screenshot of something, how do I email the screenshot?

Thank you very much!

After the most recent update I can't get in to any of my Yahoo Mail accounts. I get a page that says:

The page isn’t redirecting properly

An error occurred during a connection to mail.yahoo.com.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

I can log into my Yahoo accounts without a problem, only mail is broken. It works fine in MS Edge. I've cleared the cache and cookies and restarted both the Firefox Browser (ver 111.0) and Windows (11 Pro ver 10.0.22621).

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.

Just upgraded to Firefox 111.0. Now my Yahoo! Mail will not load. Worked fine before.

Error: The page isn’t redirecting properly

An error occurred during a connection to mail.yahoo.com.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

I changed nothing with the cookies...unless Firefox update did.

Remove or disable reading view for only AARP webpages in Firefox ...all other sites are fine..... it is a recent problem..... it keeps going to 40 % even tho my default is 120 %... as I have to click on the toggle on each new tab to be able to view pages.....again only on AARP webpages.
