Firefox Support Forum

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?

After the latest update (Monday) my Lastpass extension icon disappeared from the extension toolbar. It was still listed in the Add-ons and themes page. How do I get it visible again? I've tried to right click the Lasspass icon but "pin it" does not appear. I've deleted the extension, rebooted and reinstalled with no difference.

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.

확장프로그램을 설치했는데, 원래 대로라면 브라우저 상단 주소창 옆 도구 모음에 설치한 확장프로그램의 아이콘이 나타나야 하나 나타나지 않고 있습니다. '도구 모음 사용자 지정'으로 들어가서 직접 추가하려고 해도 추가할 수 있는 아이콘이 나타나지 않습니다. 이 외의 방법으로 사용할 수 있는 방법을 아무것도 찾을 수가 없는데 대체 어디서 어떻게 찾아서 어떻게 사용해야 합니까?

i installed a add-on program however this icon for using is not shown on browser's menu bar. there is not on personal setting, so i cannot find how do myself. wat should i do?

I'm using FF on a Mac Mini, Sonoma, and for the last few days FF doesn't open in the same position it was in when I closed it. When I open FF it's about half of the size it was when I closed it. I then drag a corner to the size FF I want, but this is a very new issue.

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!

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 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.

This is my Mac Monterey. My Windows 10 is in Safe Mode With Networking. The last update will not download. That version is 125.0.3. What's available under Windows updates does not download either. Now I am running my antivirus on my Windows to see if it runs clean. I do not know why I cannot apply these updates.

When I use google meet, I regularly get feedback that I sound far away, despite being at a normal distance from my computer. If I switch to another app, like slack, the issue doesn't present (so it's not an OS level issue). I'm using firefox on m3 macbook pro.

What can I do to fix this issue? Or do I have to stop using firefox?

I recently had to reinstall Windows, as a result of a hard drive issue. This involved reinstalling Firefox from scratch.

As such I had browser.sessionstore.resume_from_crash set to false, but browser.sessionstore.max_resumed_crashes was still set to its default value of 1. The combination resulted in a browser restore after a crash...

This would seem to imply that browser.sessionstore.resume_from_crash has either been deprecated (though that is not mentioned in the knowledgebase article), or it is not being correctly interrogated in the code. Unless I am missing something, and I do not want to go thru the entire config to see what else I might need to set...

If I am reading this wrong, please let me know if there are other entries that need to change from default. In the event of a crash, I want the browser to start with my home pages, NOT restore.

Currently on FF 125.0.3 (64-bit) - and yes, I know there is an update waiting for me to restart my browser yet again...

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.

Hello All,

Since my Firefox browser has many issues these days, I tried to reinstall it but forgot to leave the box next to “Remove My Firefox Personal Data and Customization” unchecked when I proceeded with the installation.

I don't have any manual backup of my Window 11 system or bookmarks / passwords stored on Firefox. And all Firefox folders now have a last-modified time later than the time when I clicked the installation file. Thus, I guess my bookmarks / passwords stored over the past two years are forever gone. But I would like to make sure that it is really the case so that I can move on and start feeling better.

I understand it was completely my careless mistake. But your kind feedback would really, really be appreciated.

Thanks!

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!

Why you create Mozilla account with sync, if I can't use profile which I saved on my old PC. I change my PC and now I can't use my open tabs as needed, I need to open each tab one by one. Why ??? Why I can't use saved profile on my new PC ??????

In Chrome, I can hit CTRL+SHIFT+I to open developer tools, add the Media tab, and go to the Media tab, and I can see the codec and what decoder is being used.

How do I do the same thing in Firefox?

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.
