Firefox 社群討論區

I have ordered some goods online and have been offered the option to track the goods. But I can't, because Firefox thinks the tracking page has a fake certificate.

I can go to the website of the delivery company and it has a box where I can enter the order number. This is ambiguous (more than one supplier uses the company) so it lists the two possibilities. I click on the right one and it is at this stage I get the fake certificate warning. I cannot bypass it, because trying to do so simply brings up the same warning.

I've been in touch with the suppliers. Their customer service desk can track the order with no problem. So where is the problem?

They say they can track it using Firefox on Windows, Android and Mac systems but have no Linux available. I only have two Linux systems here (Ubuntu 22.04 and 20.04), running the latest Firefox on offer (128.0.2 64 bit), both of which throw up the fake certificate problem, but with slightly different certificate dates (within the last 5 weeks), older than the genuine cert. I have pdfs of both the genuine one and one of the fake ones as produced by Firefox.

This is not a show-stopper this time as I can track the order by phone and email, but there is clearly a problem somewhere, either with both the Firefox versions I have or with the certification verification process.

If it's a Firefox issue, I don't know how to let them know.

Recently my PC has died from the hardware crash. So I've bought another PC and installed Firefox. While other browsers seem to nicely sync bookmarks and history from the previous PC, Firefox didn't do that although I have been logged into my Firefox account on both PCs and I can clearly see the other PC in devices using this account. What is the reason for that?

Hello. When opening links from a search, I would like to have them always open in a new tab. How can I set this as a preference in Mozilla / Firefox?

Currently, I always right click and must select "open link in new tab." I see the option in Settings to "always open in new window", but that is not my objective. I would like to open in new tab, so that I retain my original search results in the current tab.

Thank you.

Currently the taskbar icon only offers a few tasks in the context menu, such as open new tab, new window or private new window.

I understand that accessing about:config would allow me some other options, such as recently visited pages. And also allows me to remove those tasks.

I want to add the option to select which profile I open from that menu, instead of opening the default one, then selecting the correct profile in about:profiles that, in turn opens yet another window.

I tried adding a value "browser.taskbar.lists.profiles.enable" and several variations of that command. None worked.

Is there a way to add that option, so when I right-click the icon in the taskbar I can directly select the profile I want to launch?

Firefox would not open so I ran an old installer I had and now I've lost everything. No Bookmarks, no history, no add-ons. is there anyway to get it all back? Is everything in a file somewhere?

I use a ThinkPadNotebook with Windows. While surfing with Firefox, in a careless moment I clicked "allow" at a notification request of a suspicious website (qltuh.check-tl-ver-116-1.com). After this a few other websites opened up rapidly and soon after notification at the bottom right corner of the screen appeared. I immediately went offline and deactivated the corresponding permission for notifications in firefox. In particular, I did not follow any link displayed on the bottom right notifications.

My question is: Did simply granting permission of notification to this webiste create a security risk on my desktop? Or can I rest assured, since I revoked the permission and in the meantime did not follow any links displayed by the notification?

Thanks for help and clarification!

I just want to bring it to your attention, that since my latest Windows 11 updates, Firefox browser has been having browsing issues.

1. Basic or multiple tabs are no longer browsing as before. Pages such as: Instagram, Facebook, LinkedIn, CNN, Microsoft home Page, Google, GoDaddy, and so on.

Please note: I have cleared the Cache and internet history, and this does not make any difference. The issue remains the same.

What is causing this basic browsing issue with this version of Firefox?

Pressing Alt in Firefox in Linux (Ubuntu/Kubuntu/Linux Mint 22.xx) brings up a top menu, which is hugely annoying as I'm always trying to to a window action if I'm pressing Alt.

The suggested solution is to go to about:config and change ui.key.menuAccessKeyFocuses to "false".

But this keeps reverting itself. (Between every other reboot?). Alt will again bring up this menu.

How can I permanently disable this shortcut?

This has been going on for a long time - I, and others, can't copy info from some web sites - - CAN do so with Edge.

Followed the instructions on google to fix but does not fix. And, yes, the box in my settings is checked.
