Diễn đàn hỗ trợ Firefox

I updated Firefox and an old version remains on the "show applications" screen. I suspected it might be another profile, so I went to about:profiles and removed it, but it's still there. As I am relatively new to Linux (Ubuntu specifically), I would appreciate some help with this issue.

MacOS FF dev edition 102 When I roll my mouse over a link, in pops up the URL in the bottom left (i.e. status bar as safari calls it) but there's no indication of if the link will show in the current tab or a new tab. in safari, the end of the URL states "in new tab" if that's the case.

Firefox 125.0.1 update breaks all self signed certificates

After the latest auto update I can no longer access any of my management screens on my private network with self signed certificates. This is a real problem. I have attached a couple error screen grabs, but ALL of themn are the same. The information link says there is no workaround!

So how do I recover access? Chrome works just fine ... so it is def. a Firefox problem.

I am wondering if it is at all possible to adjust the settings when pulling a tab into a new window. For example, if I am running Firefox fullscreen I would like the tab that I pull to be opened in windowed form. I noticed that this is typically the case when using Chromium-based browsers, but noticed that on Firefox it stays in the format as the previous window. (if already windowed the pulled tab will also be windowed) is there a way to ensure that the pulled tab will always be windowed?

So, I recently had to have my PC repaired. Before sending it in (which ended in a factory reset) I exported all my saved login data to a .csv file. Now, I already changed the setting to allow it to import from a file, but when I select that specific file for import, and hit the button.... nothing happens.

No passwords imported, no popup like I've seen in so many other posts about this issue, no nothing.

How do I fix this? I need to get it operational ASAP without manually copying every single log in. from the plaintext file.

found a bug with firefox 101.0b5 website https://www.express.co.uk/ it does not display the comments for an article. Works with Microsoft Edge

1. Sites www.applevacations.com / www.cheapcaribbean.com fail to display a city.

2. in the ipfire firewall console, FF doesn't render graphs correctly.

I'm not sure when these broke.

FF 101.0 (64-bit).

Pictures are of FF vs Chrome chrome and MS Edge also work correctly. the 2 pics with more graphs are the same pages @ %50 size.

Since earlier this week my Firefox browser has been turning .jar files from GitLab into .jar.zip files, which prevents them from being used properly until renamed. Attempting to download the same files on Edge or Chrome works correctly, and attempting to download any jar files from other websites (even GitHub) also works correctly. It seems that GitLab is the only website that is affected by this.

Examples of files being affected (they should be downloaded as normal .jar files): 1. https://gitlab.com/Trafalcraft/antiRedstoneClock/uploads/3b3c84814d76810f826c3803eaca1e66/antiRedstoneClock-1.4.1.jar 2. https://gitlab.com/Aristois/ui-installer/-/jobs/2505715157/artifacts/raw/packager/Aristois-Free.jar 3. https://gitlab.com/Aristois/Installer/-/jobs/2495195255/artifacts/raw/packager/free/Installer-2.0.3.jar

I'm using Firefox developer edition (102.0b3), and already tried using private mode, resetting Firefox, and reinstalling. Since I use GitLab as a main source to upload files, many users have also complained the same problem to me, in which all of the users were running Firefox. After they downloaded with a different browser, it worked for them as well.

Hello Firefox Browser developer. When you go to view the video player does not open in full screen. There is a frame left, right, and bottom. It is equally displayed both on YouTube and, for example. In picture-in-picture mode, everything opens correctly. Cleared the cache. Opens fine for the first time. After the second loading of the browser - the frame is formed again. The problem is clearly on my end. Is it possible to install a third party player? Thank you

When I type my website in the bar, firefox puts www in front of it, which causes the warning page: firefox detected a potential security threat and did not continue to www.karinchappell.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

If I remove the www by backspacing it, the page loads correctly.

I've checked the website: "SSL is enabled on your site, and an SSL certificate was detected on your site."

When I've asked around the techies I know, I've been told this is an antiquated way of dealing with it. Please advise.

Please help me.....

Hi! I am hiding the toolbar when browsing web pages to maximize the screen spaces. However, when playing full-screen videos (all HTML5 videos), the lowest part of the video are missing. It seems like that part are squeezed out of the screen. If I uncheck the "hide toolbar" function, it fixed. See the lowest part of the attached image.

I'm using the ff dev edition, 110.0b6, but the bug also happens on my ff 109.0 OS: MacOS 13.2

I installed the Mail Link Enhancer add-on. It works, sort-of. The subject line and other fields included after the ? in the mailto address do not get filled in. Looking at the add-on info, the developer is Nick, but there is no contact info in the More Information section of the add-on profile. The add-on hasn't been updated since 2020, so I'm fairly certain that things changed since then and that's why it isn't working, but I'm no expert.

So I downloaded Firefox and logged in expecting my bookmarks to carry over after I "sync'd" it, however the did not. So I went to my old pc and did the export bookmarks thing and imported it to the new pc.

Now.. I have all my bookmarks and everything appears great. Except whenever I open a link from say my work it opens a Mozilla window that doesn't have my bookmarks. When I try to combine the windows It doesn't let me. I am also scared of losing access to the Mozilla with my bookmarks as I work from home using those. (the desktop shortcut to Mozilla opens the one without all my work)

In the attached screenshot things to note, the bookmark bar available on left isn't there on the right. Additionally in the taskbar (bottom) it shows Mozilla in two distinctly separate icons. When two Mozilla windows are open, they share the same icon on the taskbar, these do not, which leads me to believe I have two incompatible versions existing next to each other.
