I'm not a tech savvy user. Although I am using a personal network could Mozilla be interfering with the link of my Linux computer to the HP printer? Any suggestions on how to remedy this?

Does any one know how to cure this issue?

My AOL email every time I log in stops working after a while, with the following notice "No Internet Connection" shown on screen. I have to reboot Firefox and cancel the hung up Firefox application to restart Firefox and log back into AOL email each time.

I recently switched from Debian to Fedora Workstation. Everything works fine, even better under Fedora, except Firefox. There is this quirk, where whenever I wake up my system from suspension, and I try to search something, Firefox just shows a loading sign as if it was loading the page, but I see via the inspect tool that it isn't even sending any HTTPS requests to the server. I know this problem specifically affects Firefox, because other programs that require an internet connection, such as fetching mail via Thunderbird or installing packages via DNF work completely fine. In order to get Firefox to actually work, I have to completely close and reopen the application, forcing me to lose unsaved work in some cases. I've tried everything, from restarting my machine to waiting to see if it will be patched in a future update, but nothing has gotten better. Please help me. Thank you in advance.

just about every other website I request a website, says no can't connect now. (obviously good reason to find another browser)

browser gives couple lame fixes.

why don't you fix it

Hi, For a few weeks/months, connecting or disconnecting my Proton VPN makes Firefox not to browse. I must restart Firefox to be able to browse again. This problem does not reproduce every time, but it does multiple times a day. Are you aware of this problem? Thank you for any help. Regards, François

I have just download firefox, but I can't browse any web on firefox. Then, I tried firefox ESR, it doesn't work eather. Only setting page can be open. Microsoft Edge can work well (image 1 left is Edge), and my internat is OK, only Windows Defender work.

Firefox won't load any webpages. Every website I try to open fails to load, even though my internet connection is working. I have restarted Firefox and my laptop, but the problem till exists. I am using a Lenovo laptop. Please help me fix this issue

Hello Firefox Support Team,I am facing a persistent issue where Firefox is unable to open or connect to any Public IP addresses, resulting in a "Connection Reset" error. This issue happens simultaneously on two different operating systems: Windows and Linux (on the same network).Interestingly, the same Public IP addresses open completely fine and without any issues on Google Chrome.I have already tried the following troubleshooting steps, but none of them resolved the issue:Disabled HTTPS-Only Mode completely.Disabled Secure DNS (DNS over HTTPS).Changed Network Settings to "No Proxy".Set "security.tls.version.min" to 1 and enabled deprecated TLS.Disabled HTTP/3 and HTTP/2 in about:config.Performed a full Firefox Refresh (Safe Mode / Default Profile).Since the issue persists across different OS platforms only on Firefox, it seems to be related to how Firefox handles direct IP handshakes compared to Chromium-based browsers.Please advise on how to resolve this. Thank you.

Firefox stops loading websites after Mac lock/unlock I am using a MacBook with Apple M1 and Firefox 151.0.2 (aarch64). Whenever I lock my MacBook and unlock it later, or leave it idle for a longer period and then log back in, Firefox stops working properly. It appears to stop resolving DNS requests. Every website remains stuck with messages such as **"Waiting for http://..."**, and no pages load. This issue affects all websites. At the same time, Chrome works without any problem and is able to load the same websites successfully, which suggests that the network connection is working correctly. The only workaround is to force quit Firefox and start it again. After restarting, everything works normally until the next lock/unlock cycle. This issue occurs consistently after the Mac is locked or left idle for an extended period. It is significantly impacting my productivity and reduces the reliability of using Firefox as my primary browser.

Please suggest the way to fix this.
