I open up firefox and the message appears - you must be signed into this network in order to access the internet. BUT i can use the internet. This is not a problem on a W10 machine which I also use.

I receive many unwanted/junk/spam emails a day (10 to 20) in my email inbox. How do I stop this influx of junk? right now I am blocking domains, is this the best I can do?

Good Morning! I've just come back to FF after using another browser for quite a few years. Things have changed alot here, but I'm loving it all so far! With that being said, have been trying to get a few extensions set up. Main one being Open Link with New Tab. (WHY doesn't FF do that automatically? lol.) Anyway, obviously I'm doing something wrong because it just stays grayed out. I've uninstalled/reinstalled quite a few times. I know it's something so basically simple and I'm overlooking it. HELP! Thanks! Lynn

I have organized my bookmarks into various directories & sub-directories. On occasion, these directories &/or sub-directories 'migrate' if I'm not precise with my cursor movements. Is there a search function I can use without having to go through each directory/sub-directory one-by-one?

Hi Had some problems with the computer. According to Microsoft the dll error was caused by the new Adobe acrobat. Trying to fix this problem some of the websites in Firefox are having now problems. EXP. Kohl's Error code: SEC_ERROR_REVOKED_CERTIFICATE. Home Depot Oops!! Something went wrong. Please refresh page. This is only happening in Firefox with Windows 7, Firefox version 115.33.Oesr 64 bit. When I access these two websites on Chrome in the same computer everything is fine.

What is causing these errors in Firefox????? Can you please help!!!!!

I have accessed the particular website many times but today it says, "Hmm. We’re having trouble finding that site.

We can’t connect to the server at shop.naturalcompounder.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)"

Secure Connection Failed

An error occurred during a connection to cow.huntforenenst.com. Peer received a valid certificate, but access was denied.

Hi, I'm running Sierra 10.12.6 on a mid-2011 iMac. I installed Firefox 115.33.0 in March '26, but now see a "not supported message" in the browser.

I downloaded the ESR version of this browser, but when I went to copy to the APPS folder it asks if I want to replace the NEWER one that's already there. ???

Now it says I'm running it on the ESR update channel. Did I just go backwards in browsers? When this ESR expires, if a new one isn't provided then, will I still be able to use/update/install Firefox on this IOS on this iMac?

Thanks! Elaine

Why is every company from Microsoft, Google and Firefox so obsessed with changing how I have my devices set up? I do not want all the extra feed as I open the browser. Every time the browser is opened there is so many more added shortcuts to my main screen. That is super annoying when I already had in place the shortcuts I wanted. I have gone through multiple times to dismiss the ones Firefox had added to the shortcuts. But new ones just keep popping up in the shortcuts. I have also blocked all the advertisements such as sports, fit health, politics and many more that is offered that I do NOT want. It crowds up space and is VERY distracting to my homework assignments. I just started using this browser because my college recommended that I install it to my laptop because Microsoft does not support 100% of their programming requirements. I wish the settings to find this would be easier and more available to the average Joe who is not familiar when changing browser settings. Plus it switch my mouse buttons. When I have always used the Left click on the mouse to select the word that needed to be modified auto correct spelling... now it is set for the Right click of the mouse. Why does every company feel the need to completely modify other peoples stuff? Same thing with my TV connected to the WI-FI. Ads are always popping up, modifying TV preferences, moving apps around on the main screen. Every time I power up it has a new screen. Its honestly disgusting. The world around us is always changing... can our personal home lives be left alone with our preferred preferences? With out major companies thinking "Heeyyy we can make that better!" without asking from the consumer! It would be nice to have the option when powered on asking "We have a new product, would you like to try it?" allow us to select yes or no! Or just fix the old stuff that had glitches... but nah we going to keep pushing forward and annoy everyone to fill our pockets! I am NOT pleased with the product that has been recommended to me.

When trying to set Firefox to open a file on Windows 11, it is overwritten by Firefox Nightly. I have both branches installed.

This is how it goes when attempting to set Firefox as a default application in my machine:

1. "Apps > Default Apps"
2. .mp4 (for example)
3. click the button below that displays the current default application
4. Firefox Nightly appears in this menu
5. "Choose an app on your PC"
6. "C:\Program Files\Mozilla Firefox" ... "firefox.exe" ... "Open"
7. Firefox Nightly remains in this menu

I cannot get Firefox to appear as an available app in this menu. The only workaround, although inconvenient, is to drag and drop files straight into Firefox.

Any help would be much appreciated. Thanks.

My microphone (stand alone) is not being detected by the website "Babel Audio" as I am attempting to connect on the website to test out my audio. My microphone does work for other programs on my computer and my taskbar does show that my microphone is connected correctly.

Whenever I open a new firefox page externally, such as from the system tray or by opening a link from outside firefox, nothing happens for about five seconds and then it loads normally. When I open a new firefox page internally, such as from file ---> new window or by clicking a link within firefox, it loads instantly like normal. This has been happening since yesterday (3/13/26) evening.

I have already tried all of the following fixes and none have done anything:

Clearing firefox startup cache running firefox in troubleshoot mode running an older version of firefox disabling all my extensions disabling my antivirus disabling hardware acceleration disabling captive portal detection making sure both firefox and windows 11 are fully updated refreshing firefox reinstalling firefox rebooting my PC disabling IPv6 preventing accessibility devices from accessing my browser clearing my cookies
