My Firefox has started refusing to open certain websites which I have previously accessed. These include, but I suspect are not limited to: warhorn.net foambrain.com mybestjudymerch.com

Google Chrome on this computer will open these sites, as will my Firefox install on my work computer. I'm running Big Sur 11.2.1. I have tried every step on https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can and https://support.mozilla.org/en-US/questions/1290042

I have 100s of profiles that i need to move to a new computer but the names of the profiles are not .default (see attached screenshot named "Profile names on old computer") - they appear instead to be what i named the profiles.

And when I do move them to the Profile Directory, they aren't recognized in Profile Manager, I assume because they don't end in .default (see screenshot named "Profiles on New Computer" and screenshot "New computer's Profile Manager").

But on my old Macbook, they are recognized just fine. What am I missing or doing wrong?

Thank you

Users have been complaining about update nags for several years, and when a solution is found via about:config, Mozilla typically puts a spanner in the works and deletes the relevant config items like 'app.update.silent', 'app.update.doorhanger... etc.

I just want to remove the popup, not the ability to update. I'll update when I'm good and ready, and I don't need a popup each and every day nagging me to do so.

If Mozilla must ape Chrome, then aping Chrome's non-nagging update policy would be a good move.

Hi there, How can I get the horizontal print menu bar to display (with "Simplify Page" option)? It was displaying until recently, and then mysteriously just went away. I really need that "Simplify Page" option to display always (whether active or grayed-out). Any suggestions? Cheers, Stephen Gareau

Hi, The alternate search shortcuts are an excellent feature. Prior to a recent Firefox update, I was able to enter a search term and click once on one of the alternate search engine icons to perform the search with that engine.

Currently, I need to click the icon, e.g. Wikipedia, and confirm the request by pressing Enter or clicking the new item in the entry in the address bar drop-down, "Search with Wikipedia" (screenshot attached).

Is there an item in the about:config settings to revert this change and perform this search with a single click on the icon?

Thank you.

Hello, i was unable to access Google and YouTube due to "Error code: SEC_ERROR_UNKNOWN_ISSUER", i could still access Gmail and drive but those two would not budge, i was still able to access them trough Chrome tough.

I did not have any anti-virus installed, did install malwarebytes for a moment, did a scan and uninstalled it, did not do anything. Turned off windows defender and nothing happened. I did have glasswire installed so uninstalled that as well and nothing happened.

After researching a bit more i found a solution where a guy imported the required certificate from another browser so i did the same. The certificate from both these websites was "DigiCert Global Root G1A" and it was present in Chrome but it was missing in Firefox(In case its relevant), and afterward i got access to both these websites however YouTube stopped working properly. The sidebar on the main site does not show any content( https://prnt.sc/109dtjv ), the comment section wont load and also when i click on my profile it wont load as well ( https://prnt.sc/109dux1 ). As far as i am aware those are the only issues i am facing, the videos load with no problem. Everything is working properly on Chrome so i will assume its not YouTube. I tried starting in incognito mode and safe mode, the issue is still there. So what im currently assuming is that maybe i should not have imported a certificate from another browser but i could be wrong so any help would be appreciated.


TL:DR: Imported certificate from another browser to fix "Error code: SEC_ERROR_UNKNOWN_ISSUER", now YouTube wont load the sidebar, comment section and myprofile dropdown menu.

I have installed Mozilla VPN and used it a couple of times on my laptop to ue. I have also paid for it I think, I certainly provided my card details. All this happened earlier this week. I am trying to use it on my tablet. Help says go to this link (vpn.etc) , login to your account and then download VPN. Sounds good but it doesn't happen - instead I'm asked to start a subscription and give my card details and agree to a second lot of charges. I don't think it's a confidence trick but it could be. I signed up for Mozilla VPN on the understanding that I could use it on 5 devices or profiles. Hope you can sort me out, thanks.

Hello,

I am looking for a way to hide my tab bar when there is only one tab open. I almost found the solution there: https://support.mozilla.org/en-US/questions/1297983 But it is not exactly what i am looking for. This solution hides the tab but not the tab bar it self. I mean it leaves some black empty space because i use dark theme.

I kept looking for a solution to hide the container. I found this one: https://support.mozilla.org/en-US/questions/1271391 The problem is: this solution hides all the time the tab bar. No maters how many tabs opened.

I experimented mixing these two solution. I have try:

  1. tabbrowser-tabs tab[first-visible-tab="true"][last-visible-tab="true"] + #mainwindow:not([tabsintitlebar="true"]) #TabsToolbar {
 visibility: collapse;

}

I tried the other way around, with "#mainwindow" first. I tried without the "+" sign. But none worked out.

So I was having some trouble a few days ago with a website that automatically re-directed as soon as I landed on it to another page. So I happily went off in the settings and disable the automatic redirect. Now a week or two later I'm sitting here going I can't find the setting anymore? I can't even search for it and have absolutely no results you would think searching for "redirect" in the settings pain would bring it up. it's probably something that got buried in developer tools that I would never be able to turn off/toggle again unless I get lucky with the right extremely memorable and easily accessible incantation in the about : config because that's just all so well documented. Is it a "1" is it a "0" is it a "5" which one disabled / enabled what is the other options do?

I'm only able to open the Preferences window by typing about:preferences in the address bar. If I keep a Preferences tab available, I'm able to navigate to that window using the aforementioned methods.

Any ideas?

I am alarmed to learn from moderator Cor-el that FF installs a back door on my browser to load studies even after I specifically set my FF preferences to NOT participate in any study. Under Privacy and Security > Firefox Data Collection and Use, I unchecked the box to DISALLOW studies. ~ I am NOT enrolled in any study according to about:studies ~

--> How can I stop this? Can I delete all these "app.normandy."options in the about:config window without breaking the browser? Or do I set all or some to False? I am not a programmer. I would appreciate a lay person explanation.

~ The bigger question: Why is Firefox is inserting these 'studies' surreptiously irregardless of the options I set? ~

I deliberately stopped installing upgrades after v.84 to avoid problems caused by unannounced changes to functionality and the interface. Especially after the terrible changes to the print function which I encountered using another computer. But this disruptive, unwanted Print experiment appeared on this PC, despite not updating.

Thank you to the helpful moderators who can identify which about:config options we can change to false to roll back changes. However, it is not beneficial to make us waste hours to hunt these down.
