Diễn đàn hỗ trợ Firefox

This has happened to me several times and I've uninstalled and reinstalled Firefox, but then it happens again weeks, months later. It says to contact Mozilla for a correct certificate but how do I do that. There's no instructions on how to do this. Any help you can provide will be greatly appreciated. Thanks so much.

I got an error message when playing a movie that said clear cookies & cache so I did that. The movie played after I did that. Now today I opened a weather link and when I clicked on precipitation it didn't work. I clicked on a One Tab link to youtube and it opened youtube home page, not the specific link with all my history and feed lost. And some youtube videos would not play. I tried to open my Outlook email from one tab, but I just got outlook and had to re-sign in. And then I could not open an email. I had to switch to chrome to open the email. I tried to use trouble shoot safe mode. I was able to play a youtube video, but my extensions were then unavailable in safe mode, so no one tab. I am 75 and not very computer proficient, and I am afraid I will make things worse because I cannot predict the outcome of the steps offered. Mozilla/Firefox updates automatically, so I have the latest version of that and I have macOS Catilina version 10.15.5 Is there anyway to undo this mess? I need help at the most basic possible level. Can the clear cookies & cache be undone? Is my youtube history & feed able to be restored some how? Help please!!!

When I downloader the Firefox I then try tobrowse a company,etc a page comes up withFirefox logo and a line that has Google and the place for the url/ I cannot get the actual browser to open.

Ever since the latest update, the picture-in-picture function stopped working properly. If I activate it, the video will automatically go to full screen, and I need to press the full screen button multiple times to move it down to a small box. I am using Firefox on a Mac laptop.

Firefox stopped opening links in web pages like secondlife:///app/region/Kings%20Stone/224/155/22 ,WHere do I tell Firefox what application to use to handle that kind of a link?

Not highlighting selection to copy or delete so I have no idea where I am. If I cut it does cut what I've tried to highlight on my new iMac--- this issue is firefox related-- works fine in chrome and safari'... I need make this feature work in Firefox-- don't want to move away

For several days, I've been locked out of a banking website I use regularly (Fidelity) using Firefox on two different computers. However, I can access the site using Safari. I'm using an iMac 24 and a Macbook Pro. I've cleared the cache, have turned off the ad blocker for the site, and have an up to date version of Firefox. Thanks in advance for help.

Firefox will not allow my to post comments on Yahoo. I have no issues with Chrome or Safari. I get the following error message: Your comment failed to publish. Retry

Last night I was watching a video series on Amazon and the last episode won't play on my MacBook Pro. I plays on the TV and in Safari. I deleted and reloaded Firefox but the issue remains.

Every time I open a video on a website and try and enter fullscreen mode, it never lets me exit fullscreen mode. Then I have to close the entire window. Also, sometimes I have to refresh the page once or twice to even get in to fullscreen mode. Google is only showing me stuff about Firefox fullscreen mode, NOT fullscreen mode for videos, which is the actual problem.

I also did get the attached message, wasn't forsure if this was apart of the issue?

I have tried to dump the preferences, clear cache, restart, clear history.

Hey there, I was using one of my macs today and it suddenly started updating. It was taking ages and seemingly stalled, so I closed the app.

Now, all our bookmarks and history is gone. Also, the now updated version is not showing my new history etc.

Is there any way to retrieve our original bookmarks, history and passwords?

Regards Peter

Hi there,

About 4 days ago, hotmail suddenly stopped loading on Firefox (though I can still access it on Safari). I've tried clearing my cache and add-ons, etc. I've googled a ton and tried all the things I can find to try, but nothing is working. I am by no means a tech person and so I'm out of ideas and need some help. I know I can use Safari, but I really hate using it and prefer Firefox. Any ideas on what to do? I am using a MacBook Pro - Sonoma 14.4.1

Thank you so much! Jocelyn Pascall

I am using Firefox to interact with Babbel language software. I cannot get Firefox to allow me to use my standalone microphone. I tried all the Firefox recommended fixes, but I cannot make them work. I go to the "Microphone" permission setting. There is nothing listed there and it will "not" allow me to add the Babbel website? What do I need to do to allow my microphone to work with Babbel?

Computer: Apple MAC 27" 2017 model with a 3.8 GHz Quad-Core Intel Core i5 Processor Software: macOS Monterey Version 12.4 Babbel: Latest software application downloded May 26, 2022 Firefox: Downloaded May 30, 2022 Microphone: JOUNIVO Voice Microphone JV-601Pro (Connected to MAC via USB Connector)

Thank You, William A.

How to add the date of the site listed in History.

As it is there is the sidebar: History, then Name, Tags, Location, and Date but the column is empty, no date appears there.
