Firefox Community Forum

Since I updated my MacBook to macOS Sequoia, I have no access to local network pages (except 127.0.0.1, localhost and 192.168.0.1) - an "Unable to connect" error appears. Immediately after the first launch of Firefox, a request for local network permissions appeared, which I accepted, but it didn't help. I performed all the actions from this article, and also used the terminal command reset All approval status for org.mozilla.firefox and Firefox disappeared from the privacy settings. While a request for access to the microphone and camera reappeared after restarting the browser, no question about the local network appeared. The problem only occurs in Firefox (version 128.5.2esr) and does not appear in other browsers (checked in: Firefox Developer Edition, Firefox Nightly, Safari and Google Chrome). macOS 15.1.1 (24B91).

My home setup is such that I use PiHole for DNS (dual PiHoles). This includes doing DNS for my local network as well as black-hole for a bunch of Ad-serving domains. To get this to work with Firefox, I've gone through all the settings to turn off DNS over HTTPS (DoH). The documentation on this is in a multitude of places, and seems to have a lot of "this setting doesn't exist anymore" pointers, but I get it working... sort of.

Every few months (maybe every time Firefox updates?) Firefox stops seeing my local network names and starts showing ALL THE ADS. I go back through and LOOK AT THE SETTINGS (which ARE still set), but after LOOKING at the settings, it starts working as expected again for another however long. This has come to the point where I've stopped bothering to open Firefox when I need to get to my own network resources. DoH is already hard enough to turn off, but having to look it up every few months to "check" the settings so it's REALLY off is very difficult.

This has been going on for at least 8 months, and I'm only bothering to mention it now because I've noticed that I'm changing my habits, Goocrosoftle is winning.

So, MAYBE I'm still missing something. Half the articles point to settings that don't exist anymore, so maybe there's one more thing that will make this actually stick. Everything leading to the search HERE on this topic talks as if Firefox is still using the local machine's DNS, and that has not been the default for quite some time. Either way just adding my "inside." domain to the localdomains setting will not fix this problem.

This has been a problem for me for a very long time, and I'm tired of having to use chrome every time there's an update to firefox.

The issue I have is that I will get the notification saying there's an update. I click the button to update now, the browser opens the auto download page and I get a not secure connection warning. The only work around I've found is to use chrome, and sometimes I can use the "other downloads".

I'm not running a VPN, or any other networking software on my pc. This is for the full program, not the windows store app.

Secure Connection Failed

An error occurred during a connection to download.mozilla.org. The server uses key pinning (HPKP) but no trusted certificate chain could be constructed that matches the pinset. Key pinning violations cannot be overridden.

The past 3 days i have had problem with connecting to Google.Then it works then it fails. It is also telling me i am not securely connected to the site and no encryption.

Every time I boot/wake my computer, it takes at least 5-10 minutes for firefox to connect to the internet. I can open chrome or edge just fine.

I've tried reinstalling firefox, i've checked my win11 firewall settings, I've ensured that i'm not running through a proxy and have checked DNS.

Please help!

Hi All,

I know this subject was asked and answered before but for the life of me I cannot get it to work.

Ok I have V133 Firefox but this still seems to fit the bill.. [[Knowledge Base Article|https://support.mozilla.org/en-US/questions/1346987]]

I Watched the video on how to create the userChrome.css and text file. Then opened a text file inside userChrome.css, I then Copied and pasted, @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

menupopup > menuitem, menupopup > menu {padding-top: 2px !important; padding-bottom: 2px !important;}

• |*:root {--arrowpanel-menuitem-padding: 2px 8px !important;}

to said text file saved it. Next I went and set this pref to true on the about:config page to enable userChrome.css but not sure if that did this one as well "userContent.css in the chrome folder. I then closed (Quit/Exit) and restart Firefox when you create or modify the userChrome.css file.

Nothing seems to have changed please what did I do wrong? Thanks in advance for help.

hi

firefox loading very slow , when i click on a new page its so slow to load , i first thought it was my internet but i have tried on micosoft edge and that is very quick

I recently loaded Firefox 133.0.3 (64-bit) to a new computer. I signed into my Firefox account and opened Firefox. The Bookmarks Toolbar loaded but all the original icons had turned to globes and I had to open each one to get the original icons back on the Bookmarks Toolbar. The same thing happens to the icons in the Recent Bookmarks column. The add-ons also dissapear from the add-ons toolbar and I had to go into Manage Extension and Enabled them to get them back up. The problem is that when I close Firefox I have to log back in and do the same thing all lover again. I reaserched the problem for fixes but found no nothing covering this issue. Anyone have a suggestion for a way to fix this issue? Firefox works fine in my old computer. Thank you for your time.
