Firefox 技術支援討論區

Hi... I am using the latest version of Firefox (88.0) for my 64 bit Dell laptop. I have checked a few times over a period of weeks in settings, General section, the box marked as - Always check if Firefox is your default browser is checked. Underneath this line I see one line with a smiley icon indicating it is NOT. I have several times gone through the process to make it my default browser and, when checking that it is, it ALWAYS displays as the default browser. So... I have no idea why this line continues to be displayed. Anyone have any thoughts? I can find no info on this issue.. thanks Brian

The ability to edit and customize the headers and footers for printing was one of my main reasons for switching from Chrome to Firefox. Now I can't find where to do this. I don't know if it was a recent update or what but I am using Windows 10 Home. Please help so I don't have to find a new browser.

Why is Firefox blocking Flickr and Tumblr without my permission.

I reinstalled Google Chrome as a proxy and then was able to login but a day later I was blocked again since Firefox is the default browser on my PC. Frustrating to say the least. Firefox does not have carte blanche authority to block sites without consulting these sites' customers first. The URL shield is grey and when I switch it off it has the line through it but still will not load.

Suggestions please?

For days I was noticing that, after exiting sleep mode for at least a couple hours, Firefox would open up with the spinning wheel and would be completely frozen. Frequently I'd have to reboot and re-open in Safe Mode, because it wouldn't force quit. Then I'd disable the plugins when I had it open. But eventually I had to re-activate this plugin in order to stream content. I don't know 100% if this is causing the problem. Is anyone else having issues with this plugin and if so, is there a simple way to fix/debug?

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.

Hello, I have searched the internet for a solution to this, basically what is happening is I'll go about browsing, as you would. then I click on a link, maybe type in the website and it says "Hmm. We’re having trouble finding that site. We can’t connect to the server at (website) If that address is correct, here are three other things you can try: Try again later. Check your network connection. If you are connected but behind a firewall, check that Firefox has permission to access the Web." I did notice it's quite random, most websites work but every 1 in 10 I'd say I get this error, then I refresh the page and it loads.

I've changed my DNS, Removed my firewall, and reset my firefox and none of that worked, please help.

youtube video of it in action:https://www.youtube.com/watch?v=ioKKYKnrniQ

basically it just doesn't load then loads when I refresh it.

Firefox can put a search engine. My primary search engine with future Firefox versions just like I did with DuckDuckJoe I hope for help, this is my search engine link: https://rdivxe.com, thanks

I use FireFox 88.0.1. in Windows 10 (x64, ja-jp), I set it up to open last sessions.

But It doesn't work sometimes.

When FireFox is already closed, and I open files which click URLs in other programs (like a Discord, MS Teams etc.), then FireFox open them and It doesn't restore last session.

So, FireFox was closed -> I reopen the FireFox normally ( OK )

But, FireFox was closed -> I click some URLs or open Files(they are connected with FireFox) -> FireFox REOPEN ( AND MY LAST SESSION GOING SOME WHERE!! )

I don't know this problem occured from me (such as mistake of settings).

I'm wating for your kindly answer.

It's annoying not being able to use my mouse gestures when browsing addons, these forums, etc. since I rely heavily on Gesturefy for physical reasons. I don't much mind not being able to use other addons on these pages, however. Is there any way to fix this?

I note that Amazon are included in your list of "suggested search engines". Amazon is mostly a shop, so why is it allowed an unfair trading opportunity? The solution to this must surely be to allow users to type in the website of their choice? e.g I might want to use the search primarily for books and prefer " https://blackwells.co.uk/bookshop/home"

All. The answers to all the issues with security errors like SEC_ERROR_INADEQUATE_KEY_USAGE end up with "contact the web owner". In many cases for me, these web sites are not internet sites but hardware HTTP servers (e.g. like a system's BMC or iLO) and there is no system administrator to contact. The web sites open up fine in Chrome. There has to be other solutions (like setting an exception) to work around these issues. Eddy
