Diễn đàn hỗ trợ 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.

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.

My "recovery.jsonlz4" file from a previous install will not reopen my previous session (tabs) after the new installation.

Before deleting my previous installation of Firefox (for a clean install), I did two things: I created a restore point, and I did a backup of my old data.

The data consists of: bookmarks-2024-05-10.json

These folders: C:\Users\[machinename]\AppData\Local C:\Users\[machinename]\AppData\Roaming C:\Computer Files\Mozilla Firefox\distribution C:\Program Data\Mozilla-1de4eexxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Within "Roaming" I have Firefox\Profiles\xxxxxxxx.default-release\sessionstore-backups

In that sessionstore-backup, I have a "recovery.baklz4" (most recent session, I'm guessing) and three others that look like "upgrade.jsonlz4-2024xxxxxxxxxxx

With Firefox closed, I took a copy of "recovery.baklz4" (745 KB) and pasted it into the current sessionstore-backups file, then I changed the file to "recovery.jsonlz4".

I thought that when I reopened Firefox, my previous tabs would appear. They didn't. So, I went to the menu, then to History, and clicked on Recover Previous Session. That didn't do anything either. And it reduced the size of the *.jsonlz4 file from 745 KB to 6 KB.

I'm not sure what I've done wrong. Can you help me out?

Thank you.

When photos, videos, or websites are linked on a FB comment, it used to display a thumbnail preview below the comment. Now it just shows the link. On mobile, the preview appears. So I'm thinking a setting got changed on the desktop version.

Does anyone know what the issue is and how to correct?

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.

Hello, I have the fallowing issue with Firefox and the sound icon on taskbar in Windows 10 22h2, when Firefox is open and I click on the sound icon on the taskbar in Windows 10 22h2 the sound icon does not open, when Firefox is closed the issue is gone.

Any help to fix this issue would be great.

Thanks

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 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.

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

Steps for reproduce:

• Turn ON PC
• Launch Audacious player
• Launch Firefox
• Visit to drupal.org

And I have sound glitches like on radio tuning. From all software, that have sounds: players, browser, messengers. Glitches disappear after restart. I find only 2 sites, that make it: drupal.org and my local bank. With Chrome - no problems.

Without Audacious glitches can be to, but not in 100% of cases.

I've always had my firefox checkmark the "Always ask you where to save files" box. I started to download a file from Envato elements, and firefox asked me where I wanted to put it, so I pointed it to a dropbox folder on my finder level (I'm on a Mac computer). Some pop up showed up that said it didnt like the directory so I hit ok. Then I tried to download again to another location but now firefox won't ask me where i want to download the file to. And instead it just populates a file in the downloads folder called "7gp69ST8.mp4.part" or something similar. If I uncheck "Always ask you where to save files", the whole file downloads just fine to the downloads folder but I dont want that setting, I want the check mark ON so that it asks me each time where to save the file to. But its not asking me any more. So I hit quit on firefox and came back in and the issue persisted. I cleared the cookies and the issue persisted. Please help me fix this.

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
