Firefox 技術支援討論區

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?

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!

The last Firefox update, 126.0 (64bit), that was installed 2 days ago has caused various website's commentary or forums to not be displayed. For example, Yahoo finance page, attempting to read the "community" section of a particular stock such as Walmart (WMT) nothing is displayed. This happens also on news websites that allow commentary. Google Chrome does display commentary but I don't like using Google.

This is not the first time commentary has not being displayed after an update. Happened a couple of times last year.

The desktop pc is running Windows 11, version 23H2.

Thanks, Frank

ive built a new pc and have a flashing program popup every 10min. upon assistance from a really good pc guy, we've found its a firefox default browser agent with a long code.

its not listed in my scheduled tasks, eyt runs every 10min. only thing close to firefox would be thrunderbird, but iirc, mozilla and thunderbird are not longer the same company. either way. i need this thing to stop running every 10min.

My firefox now freezes when I click in the URL bar. NO solution I have found so far other than task manager -> end task and restart the browser. Occasionally that will work, other times it will immediately freeze again.

Historically I have had a LOT of tabs open, more recently less than 20 tabs. I have never seen the issue before.

Windows 10 22H2 Ryzen 3600 32GB RAM Nvidia RTX 3060 LHR 3 Monitors 2 - 1920x1200, 1 - 1920x1080

What I have tried so far: - reboot - restart firefox - "refresh" firefox - troubleshooting mode - removed all extensions - removed some extensions - reduced tabs down to a few - tried to click in the start page search instead of url bar - turned off hardware acceleration - turned on hardware acceleration - turned off TLS DNS - using only 1 window at a time instead of 2 or 3 - waited for an hour or so and window did not become responsive

None of these solutions fixed the issue. A screenshot would be useless as the window looks fine, but the UI is unresponsive.

I have Firefox on Windows, Linux, and Android. Anytime I use Firefox on a desktop, it sends me to Tornado Alley in Kansas. However, I am not in Kansas, and I don't have dog named Toto either. I am in the Detroit area. If I use other browsers, I don't have this problem. It only happens on desktop computers. On my cell phone it shows the correct location. I have already done the simple troubleshooting measure (for a year now: clearing cache, uninstall, reinstall, etc...) and NOTHING removes me from this Tornado Alley, Kansas location on the Firefox browser. If I use Chrome, Opera, Edge, etc... I don't get this problem. It must be something in the Firefox program.

hello when i write many cell code in google colab and then run all of them when output there and i want to scroll up from last cell code to go to top of page,i have lagging for scroll up in that and this problem just in firefox and in chrome is'nt problem thanks

Greetings, Mozilla Community

I'm contacting you to ask for help with a problem I'm having with Mozilla Firefox when attempting to visit the website https://proroofingcontractorgreenville.com/. The website won't load, and I'm not sure if that's because of a technical glitch, incompatibility with certain browsers, or anything the browser may be obstructing.

Has anyone else had this problem or has advice on how to fix it? I've tried removing extensions and cleaning the cache on my browser, but the issue still exists.

Any advice or tips on how to navigate the website more easily would be much valued. I'm grateful for your support in advance.

Windows 10. Weird glitch.

If I use Wondershare UniConverter's downloader function to download a video, as soon as the download starts, all Firefox open windows close. This is a recent thing, the last couple of weeks or so. I have reinstalled Firefox and UniConverter. The first time I tried it after reinstalling UniConverter, all was well. But the same issue has shown up again. I have tried rebooting my PC to no effect.

Any bright ideas welcome!

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.

I had downloaded a couple of pdfs from google drive via private browsing which were stored in my 'Downloads' folder. But as soon as I closed the window the pdfs were deleted. I had also downloaded a zip file which wasn't deleted.

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.

There seems to be something specific to the Phlearn site and Firefox which prevents videos from auto advancing. They either recommence the just completed video or revert to an earlier one.

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.

Tenho o Win 11 23H2 com Firefox 124.0.1 instalado. Há meses , devo usar o Avast Browser para acessar o Amazon.com.br ou qualquer site do gov.br. Já desinstalei tudo e reinstalei do zero , sem extensões , mas o problema continua. Alguém sabe me ajudar? Desde já agradeço.

in google and in other browsers when you have multiple tabs in a container you have an option to minify all tabs in the container. is there a similar feature for firefox,

thank you!
