Firefox 技術支援討論區

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.

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

Hi all.

My sync is only sometimes working. I notice that when saving a bookmark and trying to find it on another device. I sometimes have to manually resync it or wait for a few days to get it shown on my other devices. Same with the tab sharing across devices.. In most cases it doesn't work at all..

Here is a current sync-log: https://pastebin.com/TWugtAbm

Whenever I open the find bar while deleting the phrases and words, it shows the one word highlighted or its phrase highlighted on the find bar whenever I reopen after deleting the phrases and words. I need help for this ?

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.

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!!!

I cannot log into my account on www.1688.com. Until recently I could easily log into my account using Firefox browser now it does not work on Firefox anymore I can still login on other browsers like safari and Google Chrome. When I'm trying to login on Safari I put in my account name and password but he just keeps asking for it again and again and doesn't login. What can do about that?

I have delete cookies on, exits firefox for a while, delete cookies option turns off and all cookies are deleted, even ignores exceptions. How to stop firefox from disobeying its master?

I noticed during a firmware download with the file extension .DAT that Firefox removed the extension. The file was not recognizable during an attempted firmware upgrade afterward. This is a new issue occurring sometime in the past several months, since last firmware update. Firefox preferences are set to download .DAT files. No other settings are listed for that file extension. I verified the issue points toward Firefox by checking the download with another web browser which completed the download with the extension.

Hi, I'm trying to clear my cache and site data (in order to update my gmail signature), and each time I clear selected sites - namely gmail which had hundreds of thousands of GB cached - it just comes back. After tyring this 4-5 times, Youtube started having hundred of thousands of GB cached too!! So now, despite managing data an clearing these repeatedly, there's more than when I started. I think I'm stuck in a loop somewhere, please help! thanks in advance

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

Every time I try to login to a different page my firefox crashes.

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.

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.

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.
