Firefox 社群討論區

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).

I keep constantly crashing, multiple times. Here are my latest crash IDs:

I tried all common troubleshooting steps: deleting cache reinstalling different settings turning off adblocker/vpn disabled efficiency in task manager and set it permanently to off in FF

I used to have 1000+ tabs in 2016 no issue. I had problem in past with Firefox using 100% CPU which now it is not using only like 50, but memory is getting full 89% i use also large page file on ssd. Problem is even when i restart firefox it is slow with low RAM usage! SO that's not it! Even 5 tabs sometimes it is slow!

It is so damn slow it drives me crazy! I tried also Quantum in past when Firefox has 100% CPU usage bug and it was only tiny bit better but still caused 100% CPU usage!

All other browsers are anti user cannot even stop Autoplay literal terrorist Firefox is only normal browser unfortunately performance compare to 2016 got absolutely abysmal! I had this problem even in-between reinstals of OS so it doesn't seem it is me. I play demanding games no issues on my PC...

When saving images from websites using the save image as feature, Firefox will freeze up and not register any mouse click or anything instead making a ding noise every time is register a mouse click. This will continue for like 30 seconds before it becomes normal then it will repeat this for every image. How can I solve this?

On ubuntu oracular 24.10, when firefox is launched, it tries to open a UDP listening port on all network interfaces which is not acceptable on many levels:

/usr/bin/netstat -tunpevaW|grep firefox udp 0 0 0.0.0.0:48654 0.0.0.0:* 1000 881247 178766/firefox

Is this behavior specific to Ubuntu or is it implemented by design? This must be a no go by design: if it needs a UDP port for some reason, it has to open it on the **loopback interface (127.0.0.1)** only.

For no apparent reason I suddenly found that I could no longer browse via duckduckgo or Google (but could through Edge!). The on-screen response just informed that the sites were not available. I had no idea what could have caused this but a Microsoft fault search identified it is a DNS problem. I prefer to use the duckduckgo and need to resolve the DNS situation. Is this a Firefox problem, and if so, how do I fix it while still maintaining security?

Is there a way to make the URL high lighting of the domain more obvious? I find that most people can barely see the highlighting and I'd like to make it obvious (bolder and red, or highlighted in yellow, for instance.)

Can this be done via userchrome.css?

Thanks,

Attempted to do an Firefox update more than a month ago on my HP (microsoft windows) computer. Everytime I open my computer I gt the Firefox Crash Reporter Window. When I hit the Quit firefox box it submits the crash report and then I X out the box. I cannot use Firefox as a browser. The DISASTER is that I CANNOT open any files previously downloaded while using Firefox (eg PDF files). I get the crash report box. I NEED these files!

Please HELP!

I received a notification that i could not connect to the internet without logging in. I tried the remedy suggested by other users (2020) and succeeded in removing this notification but still cannot access internet from my Mac computer. I have been a mozilla user for many years and have not encountered this oroblem before. All my other devices are working.

I get the USPS informed delivery emails that show what mail is arriving daily. Whenever I click the "dashboard" link, I get:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. If I go to the site, and click a link, the same thing happens. This doesn't happen with Chrome where links function normally. So, I think there must be a setting somewhere preventing me from accessing the links. I tried turning off "Block pop-up windows," but that had no effect.

Thanks, Ed

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" option.

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.

I have Express VPN and use Firefox as my default browser. This morning I cancelled the autorenewal of Macafe and uninstalled it from my HP Laptop. Now I cannot access the internet if the VPN is activated - using Firefox or Edge. Thank you
