Firefox Community Forum

Hi Mozilla Team,

I'm currently using Firefox version 142.0 (64-bit) and I'm having trouble setting up a proxy. I've tried configuring it through the usual settings under Settings > General > Network Settings > Settings..., but unable to configure the Proxy in Firefox 142.0 (64-bit), but no luck.

Is there a known issue with proxy configuration in this version? Are there any new settings or changes I should be aware of that might affect proxy setup?

Thanks in advance for your help!

I like the Firefox browser and Firefox was working fine for months but Firefox did ask me to do another update today. I did the update as requested and after the update Firefox will not connect to any websites on my desktop despite an excellent internet connection. I cannot find anyway to contact Firefox directly. For major problems such as a 100 percent failure rate to connect to any website, Firefox should provide direct help to the user as to the current major problem. I appreciate user ideas but Firefox should offer some help for major problems as the likely solutions can change over time. Hopefully if Firefox oversees user questions, someone at Firefox tech will at least respond to my question on this website or better yet contact me directly.

The problem may well be the update itself. The Firefox browser is working on my smartphone but not the desktop internet browser. I have some browser settings that I do not want to lose which a complete Firefox removal and reinstall would likely cause. Any suggestions from fellow Firefox users are appreciated and I look forward to them. Have other Firefox users experienced this major problem?

Thank you.

[redacted] problem you [redacted] im having issues with the video and ads as all of my apps are disabeld nothing works and firefox it self causing probs and no one is helping out.

The Help is recommending clearing the startup cache, but I don't know what that is so I can't decide if it's something I want to do. Is it the same place that stores all my cookies and other saved material, or is it something different? If it's different, what does it store and why would clearing it be useful?

I know little to nothing about computers. My Mozilla account says it is disconnected whenever I come online. I do not manually disconnect ever. Keeps telling me that it cannot detect proxy even though my proxies are set to off.

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...

The following is what happens when I try to logon to AT&T Yahoo mail/Currently.com "Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later. If you were using an app, close this page. Otherwise, start over."

For so, me reason i have lost my connection to FireFox. It was in the last week. I was surprised because i have been using it for a few years. Can you help me to be able to use it again please?

BARRY HATHAWAY 14 SPINNERS COTTAGES LONGFORDS MILL MINCHINHAMPTON STROUD, GLOUCESTERSHIRE GL69LP. UK

I am on a MacBookPro running MacOS 15.5.

My FireFox automatically updated to 139.0.4 on June 10th. Since then, my ability to access the internet with FireFox only has been intermittent - I can connect for a variable number seconds and then it disconnects for minutes or hours. I have no problems connecting to the internet with Chrome or Safari, or with other applications. My perusal of the forums leads me to believe that it is the latest update that is causing the problems.

Has anyone experienced this problem and/or does anyone have a fix? Thanks in advance.

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

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!
