Φόρουμ υποστήριξης - Firefox

This has been happening for months now, on multiple devices (I have tried at least 3 different devices), and on multiple networks.

I have read the articles in here, but they just want me to check network configuration which is exactly the same for all browsers.

If I restart firefox it starts working again.

How can I prevent it from breaking randomly? This is the only browser having issues, I'm almost positive is some bug and not a configuration thing, given that it happens under multiple circumstances and devices, while Edge and Chrome simply keep working just fine.

There is no consistent repro I can give, afaik it is just random, at some point Firefox just decides to stop working and I have to restart it. This disrupts my work and browsing activities as I can lose progress on input forms and similar actions.

HI, I have a Mac with El Capitan OS and Firefox 78.15.0esr. Recently I can´t open some websites: ChatGPT, Likendin, TunnelBear, Wester Union, etc. Before everything was working perfect. Please HELP! Thanks friends :) When I try to open this website, nothing happens, nor an error, sometimes in certain website it keeps retrieving and thats it.

Many thanks,

I've been using the Firefox browser, and recently when downloading files with Firefox, sometimes it prompts: .part could not be saved, because the source file could not be read. # see image #1 I'm trying to download file to disk D. But the fail tips is download .part file to disk C. Maybe firefox is using some file cache policy which I don't know. I also checked both two location, my account have read/write access.

I can try to resume the download, and the download progress will increase, but about half a second later it will fail again. If the file is small and my internet speed is fast enough, after several attempts the file will eventually download successfully. # see image #2 I have tried using "private window" or enter "about:profiles" to create/use a new and clean profile, but the issue still persists. # see image #3 I tried using other download tools like "Internet Download Manager", and the download was successful. It's ok for use chrome to download the same file to same disk location. The problem recently emerged, it didn't exist before. At least a month ago, the same computer didn't have this issue. I'm not using parental controls.

I use firefox on fedora 38 and after update firefox about a month ago . i got this error when use private mode ,for thai languge it just error but in normal mode it ok .

After just turning on my computer running Windows 10, I opened Firefox. I open 1 web site and noticed my computer showed a (16) prefix when loading Firefox. I opened the Task Manager and it showed that there were 15 instances of "firefox" running in the background. All showed a UAC Virtulization of "Disabled". But they also showed using 638.8MB of memory. I do not know whether these are necessary files that must run in the background or if the number of files indicates that my system has been hacked and someone else is in my system from outside. Any suggestions as to validity of these files running or how I might confirm that they should be running. I have noticed the number of excessive background files before but the number is never consistent which makes me fear I may have been hacked.

I have an iMac with Sonoma 14.3.1 with Firefox 115.9.1 esr . It is for personal use, not for a business. I just learned that there is another Firefox version (124.0.2) which is not esr....

Which version should I use and why?

If I should use the "normal" version, how do I replace the esr version with the "normal" one ?

Thanks.

I recently got a new computer. Installed firefox onto it. Brought over my profile with all my data and bookmarks. But for the life of me, the page would just sporadically flicker. I tried messing with the settings; performance settings; hardware acceleration. I tried refreshing firefox. But nothing.

I am running the latest updates to Windows 10 Pro x64. One of my monthly bills is paid at

1) https://e.synchronyfinancial.com/

which, in Brave, redirects to

2) https://lowes.syf.com/accounts/login

Inputting either link in Brave gets me to the finish line but the first link above fails in Firefox with the "Secure Connection Failed" message and dumps me at https://www.synchrony.com/accounts/. The second link does the same.

Is there any way to troubleshoot the problem?

I HAVE tried shutting-down Malwarebytes but the result was the same.

This is the only site on which I have encountered this issue. All that I can determine at the moment is that that certificate is from DigiCert and the expiration date is in 2025, i.e., this is not a Symantec cert.

I don't use Google Chrome browser nor do I use MS Edge. After using the Mosaic browser, I switched to Netscape Navigator, then to Mozilla, and, finally to Firefox. I am not looking forward to migrating to another browser. ;-)

I had used and uninstalled Chrome, and others. All I have is FF and ME. Some times when I attempt to open a web page, FF fails and I have to use ME. But other times ME fails and I need to use FF. I recognize that all browsers other than FF are the same or similar basis. So, how can I stick with JUST FF. And not have to keep ME updated or active. Just let ME sit there unused. Why can't FF work with all web sites? Is the problem with them or with FF?

Download files (pdf, xml) don't open in application (acrobat, firefox) since 125.0.1 Firefox version from IBM Power server with Ubuntu :

The message is "Fichier non téléchargé - Risque de sécurité potentiel" that is "No downloaded file, potential security risk" :

When we download a pdf file from the server, the "choice box" allow to . open in the browser or . open in Acrobat or . download on my PC. The opening fails with this message. This is the problem. The download on my PC works and when I open the file from my PC it works also.

We need this function of opening a pdf or xml directly from a server IBM Power with Ubuntu. It was OK for several years until 125.0.1 Firefox version. We had no change on the IBM server.

Can you repair this problem quickly. My PC uses Windows 10

Thank you Patrice Castejon [removed phone#]

Every once in a while, maybe once or twice a week, I'll press Cmd+L to highlight the address bar, type a URL for a new website, and press enter, and instead of going to that new website Firefox just reloads the current page. It seems that this happens exclusively when the current website is gmail.com. (I might be wrong) I can't remember it happening on any other website. This problem has been occurring for me for the past year at least. Any recommendations?

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

How can I get access to my own site again? I have been able to access joycefitch.com for years but today I can no longer access it from Firefox.
