Hi. I have a Dell Inspiron, it’s a few years old, and my computer is running windows. Today I was on a website, doing my assignments as usual when randomly the internet stopped working on the browser (I was on the web for about an hour before this). There was no change to my behavior, I had been on the same site for the whole hour, and had been interacting with the site during that time. My computer still says it’s connected to the internet, and I was even able to play an online game on my computer that I had downloaded, so it looks like my computer is connected to the internet. I’ve tried to clear my cache and open private windows but that didn’t help.

In Firefox, and only in Firefox, I get 'Failed to verify your identity' on these sites. I have updated MacOS and Firefox, rebooted, tried a different DNS, and disabled all of my extensions. With extensions disabled I don't get the error, but the login site won't accept my login at all. See the attached image. I can't think of anything else to try.

In the last 48 hours I haven't been able to access the following - https://www.co-operativebank.co.uk - they do not appear to be the problem - when I try the link the 'retrying' symbol on the top left of screen (?taskbar), flashes extremely rapidly and it appears the system can't find the website. Are you aware of this issue.

Every time I start Firefox lately, it keeps prompting me: "You must log in to this network before you can access the Internet." I have no idea what this means and have no problem accessing the Internet in any case. What suddenly started causing this !#@%$ message and how do I turn it off?

(Sorry if the wrong area.)

I'm curious and play with Node-Red a lot.

Just now I am playing with the `http-request` to explore web pages.

I press the `F12` key and the tools pop up and I go through some basic things.

I see/get just about nothing. See pic (Don't know to make it inline.) But the name says it all.

So I've pressed the `F12` key, clicked on the NETWORK and REFRESHED the page.

Now with Chrome.

Whole different set of stuff.

Someone - please. What's going on? I'm not understanding the huge difference with how things are shown.

When I click on Firefox and the to my email it says there is a problem with my internet. My internet is up and running fine. I have done everything it says Firefox can't connect to the server at mail.yahoo.com.

Firefox is causing my wifi adapter to shut down

Running firefox for any length of time will shut down my wifi adapter at a random moment. The only solution is reboot

Using opera, the problem does not occur, I can run opera continuously without problem. Running firefox at anytime will cause the fail at some point.

Im running windows 11 I have run firefox in safe mode Disabled all addons Set to “No Proxy” Disabled power saving on the adapter Replaced firefox with the ESR version 140.8 , previous version was the latest I note that there are up to 11 firefox process instances in task manager (all cleared when firefox is shut down) Firefox is set to update automatically Several updates have occured during this problem Disabled hardware acceleration Cleared cache Latest wifi driver And a few more that I cant recollect at the moment

Running out of hair to pull out

Any idea’s?

The font size in "Manage Bookmarks" is way too large, both in the sections list menu on the left and the list of bookmarks. I checked my userChrome.css file as well as the layout.css.devPixelsPerPx entry in about:config and there's nothing there to explain why only the "Manage Bookmarks" text is so large.

It's possible I changed a setting somewhere that's causing this. But I'm stumped re: what setting might be controlling the font size in only that UI. All other Firefox text sizes are good.

Thanks to anyone who knows where I should be looking

Firefox 134.0.1 (64-bit) Windows 10

Setup: macOS Tahoe (26.4) and Firefox 149.0

=

Behavior: Out of the blue this morning, every website I try to visit in Firefox returns "Looks like there’s a problem with this site". Every other browser works fine.

Things I've tried, that haven't fixed it: - Ruled Out DNS: Sites like 1.1.1.1 and my home router's IP return the same issue in Firefox, but also resolve in any other browser. - Firefox Safe Mode: no fix - Deleted All Settings, Reinstalled Fresh: - Removed the Firefox App, deleted:

       - ~/Library/Application\ Support/Firefox
       - ~/Library/Caches/Mozilla
       - ~/Library/Caches/Firefox

...and then downloaded and installed 149.0 fresh. - Refreshed Firefox (via [link] - about:preferences (toggled between FALSE and TRUE, testing each time) via this YouTube video

- network.dns.disableIPv6

- network.dns.disablePrefetch
- network.dns.disablePrefetchFromHTTPS
- network.dns.disable

....and in desperation, I checked my Mac for Malware (clean)

I'm at a complete loss: every other browser works, but Firefox is a 100% fail for all websites. Any thoughts?

Firefox 147.0.4 on macOS 26.3 does not work via SOCKS proxy.

Firefox 147.0.4 on Windows 11 x64 works fine via the same intranet SOCKS proxy, with exactly the same settings.

The advantage of Firefox is its flexibility. It supports its own SOCKS proxy settings, independent of systems-wide ones. Unfortunately, it seems this Firefox feature is broken on macOS (but Windows version works perfectly).

Safari 26.3 (21623.2.7.11.6) and DuckDuckGo 1.177.0 (625) web-browsers that use system-wide macOS SOCKS proxy settings also works fine with this intranet proxy server. So it seems SOCKS proxy server itself is OK, and the problem is confined to Firefox on macOS.

Has anyone seen Firefox 147 on macOS work via SOCKS proxy? Is there a principal difference between how Firefox handles SOCKS proxy on macOS vs. Windows? What might be the best way to address the problem on macOS?

Thanks!

Hmm. We’re having trouble finding that site.

We can’t connect to the server at data.digital.costco.com.

When I opened up Firefox this evening, websites stopped working if "DNS over HTTPS" is set to "Max Protection". In some instances, such as YouTube, the website loads, but it acts like you're offline and tells me to turn on my Wi-Fi even though it's already on and running fine. Weirdly, it seems that setting DNS over HTTPS to Max Protection, loading a website, set DNS over HTTPS to a lower setting, and then reloading the website fixes the issue, but it'd still be nice if we didn't have to go through the hassle at all. Thank you for your time and patience.

Sincerely, Watching Forests
