Diễn đàn hỗ trợ Firefox

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.

Mailfence.com is my email provider. I've been with them for years. Two weeks ago I am suddenly unable to connect with the website. My ISP is Comcast. My next door neighbor also uses Comcast. He can get to mailfence.com just fine. Can you please help with this issue. Comcast has declined to provide any help. Thanks.........Bob Horning

why does firefox blocks incoming http conection to localhost:8080 when I try to obtain a google oauth2 token using oauth2.py ?. The Google server returns the token via http to loaclhost:8080 and the port is blocked by firefox.

Increasing "network.http.connection-timeout" setting in Firefox to a big number – say, '9000', does not change the time period after which "The connection has timed out" message appears (the default value is '90'). Changing it to '0' makes this message appear even faster than when using the default value.

Please let me how I can increase timeout to a big number.

Thank you!

When trying to connect to sites from Google search or directly eg for Booktopia. I get a message saying

Firefox can’t establish a connection to the server at www.googleadservices.com.

I am using the U.S. version downloaded from English US version https://ftp.mozilla.org/pub/firefox/releases/138.0/linux-x86_64/en-US/ and CIRA is the default DNS over HTTPS which is a Canadian provider. Why is it the default for a U.S. downloaded version of firefox ? When I tried to use the service it did not work and the documentation is outdated and does not direct the user to properly set up the CIRA version of DOH. Is ther an updated document ?

Firefox is making my browsing experience bad. Even normal searches are having connection error, for eg:- like searching meaning of a word, trying to explore something, etc. It always says connection error and says that connection is not safe. Well during writing my experience I again tried and this time it's okay, but I'm sure it'll happen again so please look up on this problem. Thank you.

i'm trying to use policies.json to whitelist pages user can visit. When I apply changes, after browser restart I see it reacts (I use correct file), I use the template of: { "policies": { "WebsiteFilter": { "Block": ["<all_urls>"], "Exceptions": [ ....

here is see on adding an exception item - it is allowed, on removing it is not. I have a system running on http://localhost:8090. I tried multiple patterns and none of them allowed me entering my page: "*://localhost:*/*", "*://127.0.0.1:*/*", "http://127.0.0.1:8090", "http://localhost:8090", "*://www.localhost:*", "*://www.localhost:*/*", "http://localhost:8090", "http://localhost:8090/*", "https://localhost:8090/", "https://localhost:8090/*", "localhost:8090", "127.0.0.1:8090",

when changing: "Block": ["<all_urls>"], to "_Block": ["<all_urls>"],

I can open my page. I checked in console if there are any requests to other domains/ports - no. It makes single GET request to http://localhost:8090. What am I doing wrong?

My Firefox server keeps losing connection to the internet! It as been going in and out for short periods of time, but now it has been down for almost an hour! I’m going to switch to another browser if you don’t fix this!
