Dear all, How can I import setting from one computer to lots of another computers for firefox setting? For example, I have setup setting as attachments, how can I import to another computer quickly? Thanks a lot.

It usually happens when I loading page or watching video on YouTube/ Bahamut Anime(ani.gamer.com.tw). When it occurs, the video still can play until the video cache empty, and after switching to another and switching back, the page becomes all white except a loading circle at the center. This situation takes about 3~5 minutes. I have tried refresh firefox, and disable all addons.

when I try to open Firefox it says Firefox is already running but is not responding the old Firefox process must be closed to open a new window, i don't know how to do that

My dad did somethink with Avast antivirus(at least he said so) and after that we have no search engine available. If you try to type something in a serch bar you can only open direct links. Default search engine button in the settings does not respond and even following instructions on the site I can't add new search engines. Tried Google, YouTube and DuckDuckGo but to no avail. There is just no option to add new search engine.

P.S. Don't know how to reach russian-speaking support, so screenshots are in russian with some explanations on top.

I have Firefox 78.7.1 on my Mac. For some reason, the Top Sites and Highlights are not displaying on my home Page or on each new Tab. I have tried adding sites and they won't be added. I have restarted Firefox in Safe Mode and in Refresh mode - made no difference. I have made sure all the correct boxes are clicked in Preferences - General, Home and Private/Security. Where to next?

Hi. So I have installed Firefox Nightly on my Windows laptop. The browser refuses to start up after restarting post update. I have already tried uninstalling and reinstalling the browser and even using a whole new profile to eliminate the obvious causes. The behaviour is not predictable. Sometimes it occurs after the first update post installation and sometimes later after 3-4 update cycles but it does happen for certain. If it is of importance, my laptop is locked down by my company's IT admin to prevent software installations. So when I have to install Nightly using the msi, he puts in his password. I am just wondering if that is what is messing with the Mozilla Maintenance Service trying to update the Nightly installation.

I am trying to update the primary email associated with my Firefox account. My primary email is listed as <primary@domain.name>, for example. My secondary email is not assigned. When I try to add <preferred.email@domain.name> to my secondary email, I get the message: "Secondary email must be different than your account email"

I do not see this "account email" listed anywhere. Where do I find it, and how can I change it?

Many thanks, bd89

How do I make my browser display go back to the settings that it had on 2 June 2021? I am very unhappy with the last update which customized my browser. The look is awful compared to the last iteration. I was happy with what it looked like before. Whoever thought that the tabs belong at the very top of the page? This update is very aggravating. What do I change it back to what i had yesterday? I'm running Windows 10, and I think I have Firefox Version 89.0. Thank you.

for my online examination purpose i had checked a system diagonistic test in that when i check the chrome browser its showing there is s speaker but when i search in firefoz its showing its not available
