Форум підтримки Firefox

Hi there!

I'm trying to troubleshoot why firefox isn't connecting to my DNS over HTTPS instance running adguard home. Every other device (including another laptop) is able to set the DNS over HTTPS and connect successfully - but my desktop PC instance gets NS_ERROR_CONNECTION_REFUSED. Despite multiple reboots, ipconfig /flushdns, release/renew, etc...

Even my android phone is able to connect to it using the "private dns" feature (uses port 853 instead of 443).

I've been able to verify https access to the DNS server and it's querying successfully. It's just this one instance it won't connect.

Hi,

I recently facing an issue that the Firefox browser randomly maxed out my RAM and went unresponsive. Like the screenshot below, I am only trying to open Facebook and Instagram, 2 tabs.

I have tried to open about:memory and about:processes to monitor but it just went unresponsive and both the monitoring just hanged.

Have no idea why the Firefox process taking up so much RAM. Need help.

I've followed all the recommendations. Problem still happens in troubleshooting mode as well. Doesn't allow sign in either. Have reloaded all C++, uninstalled, reinstalled, restarted. No links or pages will open.

I was able to open reddit.com without any problems earlier, but recentrly I'm not able to load it up anymore. The loading screen is eternal and it doesnt show any kind of error (unless it tries to connect for too long like a couple of minutes, then the error does shows up). The site still sends me notificarions through the browser though. Any other site loads up without a problem. I tried to use methods mentioned in the help article (turned off proxy, turned on network.dns.disableIPv6, deleted cookies and cache). In other browsers (Edge, for example) reddit.com loads just fine. Please help me if you can.

This isn't the first time this has happened. After each occurrence, I have to completely uninstall the browser and reinstall it from scratch. This means I have to reopen all my tabs, which is very annoying. In Chrome, I have had a large number of tabs open for many years and it works fine.

With Mozilla, something terrible is happening... I have many tabs open in Mozilla, and there comes a moment when, upon launching the browser and opening two or three tabs, Mozilla starts consuming up to 10 gigabytes of RAM. If I open a few more tabs, the browser crashes. I don't need to open 50 or 100 tabs, just 7-8-10 tabs are enough to make the browser crash. Moreover, if I open a new tab and go to google.com, the browser takes a very long time to load, even if it's the second tab.

This problem has happened before. I don't do anything with the browser, just visit sites like YouTube.

Clearing the cache and other recommended actions do not yield positive results. This is very annoying. Mozilla is my first and favorite browser, which I have been using for almost 20 years. I wouldn't want to uninstall Mozilla.

Always shows "Failed to check for updates" On version 125.0.3 and still says needs to be updated. Then just run the install again and then it stops for a bit still on same version and then shows up needing update...been doing the same thing for a while now.

I often have many tabs open (25+) I have made it so tab shrink way more then normal (I like the way chrome handles tabs where they basically just shrink infinitely. Firefox doesn't do it's even with my twerks but ohwell.)

so when i want to click on a tab with audio playing at a small size i often mute the tab instead of clicking on the tab

Where and how can i remove the mute button that appears when hovering over tabs with audio playing?

I have never found that mute button useful so removing it will not impact me

Secure Connection Failed

An error occurred during a connection to www.healthpartners.com. Certificate path length constraint is invalid.

Error code: SEC_ERROR_PATH_LEN_CONSTRAINT_INVALID

This seems to be caused by Firefox. I don't have this problem with Edge, Chrome or Opera

I purchased a new computer, was finally able to download Firefox. When I go to use it, frigging Microsoft BING come up. How do I fix it? Thank you for your help. Susan

p.s. I am at work, the new computer is at home., The version of Firefox was downloaded yesterday and the operating system is Windows 11

I've had recent security issues and have had a couple actual breaches. Having two accounts so similar to one another caused some unnecessary confusion during a panicked burst of changing passwords. Can we merge them?

I have always been a Firefox user and all of a sudden I cannot get into my MS 365 Sharepoint if I am using Firefox, if I use Edge I can get into the accounts.

I want to use Firefox not big commercial browsers.

The following error keeps happening constantly in Firefox ESR 52.9:

Description Faulting application name: plugin-container.exe, version: 52.9.0.6746, time stamp: 0x5b2bc061 Faulting module name: mozglue.dll, version: 52.9.0.6746, time stamp: 0x5b2bbbde Exception code: 0x80000003 Fault offset: 0x0000fb33 Faulting process id: 0x0x35F8 Faulting application start time: 0x0x1DAA06C630DBB2E Faulting application path: C:\Program Files (x86)\Mozilla Firefox V52.9 ESR\plugin-container.exe Faulting module path: C:\Program Files (x86)\Mozilla Firefox V52.9 ESR\mozglue.dll Report Id: 1e159f0c-62cf-4695-8ef2-861f89c36041 Faulting package full name: Faulting package-relative application ID:

Any ideas what is causing this?

Thanks!

using Win 11, Firefox browser, Google search. subfolders are listed but will not open. Using Bing they do open but I prefer Google. If this is a Google problem or a Win 11 can you steer me in the right direction. Thanks My email is artsiii@aol.com

Well, since I changed to a new computer with Win 11, videos on Facebook don't play right. They are videos that are posted by various people and real entities. They are not smooth. They start to play and immediately pause then jump forward then pause and jump forward. If I copy the link and go to Chrome, paste the link and play the videos, they are normal Never did that on my old computer. Any ideas why the videos don't play normal?

CVE-2024-4367 has been announced several days now with MITRE and CIS. There is also an issue/advisory on the github repo for PDF.js which appears that the fix has been merged into the master commit of PDF.js (https://github.com/advisories/GHSA-wgrm-67xf-hhpq).

The vulnerability is pretty serious and yet there is no Security Advisory from Mozilla on affected versions, etc. (https://www.mozilla.org/en-US/security/advisories/)

Is this normal and I am just being impatient?

I keep getting this msg. will not open pages and will not restore "Gah. Your tab just crashed." I had to use EDGE to contact you will not open in fire fox. Please help. [telephone number] Steve Badaracco

bold textExperienced Firefox browser session freezes a month or two ago. It seemed that some March/April '24 fixes/patches stabilized the app. They are occurring again with increased frequency. What should I do to avoid this problem or switching to another browser? Thx
