Firefox Community Forum

Hello everybody, I am using Firefox/Zen Browser in Linux and having an issue which bothers me a lot.

I am using Firefox for PDF viewing and was not having this issue in Windows. I don't know why, Firefox changes locations of PDF every time with something temporary rather than it's original place and it makes impossible to see them without reopening it via clicking. Is there any possible solution for it? I am having this issue both in Firefox and Zen.

For the love of God. Effective yesterday, why can I no longer open a new tab in Firefox browser on a Windows laptop? Is this a bug or was it an intentional update to delete the visible 'open a new browser' plus (+) icon, and make it elusive, frustrating, and impossible to open a new tab? I found a workaround (right click and select the new "New Tab to Right" option from the list of drop down options), but this circumvention is mindboggling and inefficient at best. Please help. One of the things I have loved about the Mozilla organization for the last nearly 20 years of using Firefox has been the organization's dedication to make internet browsing simple and safe for users. Replacing the 1 step 'open a new browser' plus (+) icon with a 3 step right click move is the opposite of simple. Please troubleshoot.

I am trying to send an error report for a website to Mozilla. I got to the menu (3 vertical lines in the upper right) but there is no option to send an error report.

I have been using container tabs to juggle my corporate and personal github accounts. Until very recently, clicking a link from another app (email, etc) would start to open a new tab and then pop up a dialog asking me to confirm which container to use (see first attachment).

Unfortunately, now when I click on links it just loads straight to my "OSS github" container, which naturally produces a 404 error because my personal github account doesn't have access to the corporate repo (see second attachment).

At first, I thought I had accidentally clicked the "remember my decision" box. But the confirmation dialog still works if I open a new tab and paste the link in the address bar. It just doesn't work when other apps try to open a link in Firefox.

Is the new behavior intentional? Or did something accidentally break?

I currently can't stream anything, and this keep getting this message: Widevine Content Decryption Module provided by Google Inc. will be installed shortly,but it never installs.

I have a macbook air and am currently running macOS Sequoia version 15.0.1.

I tried uninstalling and reinstalling, removing extensions, clearing cache and data, unchecking and then checking back again the reproduce drm protected content but nothing has worked.

WSJ did some sort of update and now things are broken in the regula browser. I've tried disabling all my extensions, putting multiple sites on the cookies exceptions list and turning off protection in regular mode and it does not work. Private Browsing works out of the box no issues.

The main way to know if you have issues is do you see the stock ticker near the top of the webpage, your name with account info, and some drop down windows. The Live Update sub-websites are broken. I think WSJ on some sites like those thinks I'm not logged in or can't verify I'm logged in.

Its weird. I've had similar things on FireFox before, what is regular mode doing? Why does Private browsing work? Can I somehow "force" the same settings in a regular windows on a per Website basis? This doesn't seem possible at this point.

Hello,

There has been an upgrade of Firefox ESR to version 128.3 on Debian 12 bookworm.

Before the update, I could play videos, now I can't.

I precise I can play videos on Chromium, or with the video players.

I have libavcodec58, libavcodec-extra59, ffmpeg 5.1.6 packages installed.

There is an error in the console: Media resource xxx.webm could not be decoded. Specified “type” attribute of “video/mp4” is not supported. Load of media resource xxx.mp4 failed.

This command seems to indicate the session is X11 and not Wayland: ``` loginctl show-session 1 -p Type Type=x11 ```

I use Zorin OS 17 Pro and Mozilla Firefox for Zorin 1.0 Version 132.0 (64-bit).

Currently I get an error after logging in to gmx.net “Your browser is not supported.

You are trying to log in to your GMX mailbox with an outdated browser. For security reasons, this is not fully possible. We therefore recommend that you use an up-to-date browser. ”

Can you please fix this error?

I've noticed recently that some Unicode characters are not rendering properly on some websites. Specifically the Unicode characters for Mathematical Bold Capitals, though there may be others. I've noticed this issue on Twitch and GitHub. Screenshots for the repository sainnhe/everforest are attached along with the Inspector. Notice the characters do not appear properly on the webpage but are rendered just fine in Inspector. I also attached the screenshot for Unicode Mathematical Bold Capital E.

I am running Firefox version 132.0 on macOS Sequoia 15.0.1. The problem remains in Troubleshoot Mode. The problem does not appear in Chrome or Safari. The problem does not appear on my iPhone or Android tablet.

In posts with similar issues I've seen the suggestion to toggle "Allow pages to choose their own fonts", the issue does not respond to changing this setting (it is on in all the screenshots).

Hi there, since yesterday I'm dealing with numerous functionality issues when I use Mozilla Firefox on my laptop. I've noticed that the last update was on 29/10/2024, so that could be the problem. The problem is that when I browse the tabs are crashing and that happens almost every time I browse after a few minutes (sometimes seconds) and it happens with many different web sites. Since mozilla is the browser that I use most this is making my life real difficult. Thank you in advance, Sotiris

I use Firefox 128.3.1esr in my Debian 12.7 Is there anyway to close last tab without exiting the browser? I mean after closing all tabs, I want Firefox jumps to homepage. Thanks for your help.

I can't watch youtube videos because the player is hidden idk, i just see blank space in the place where the player should be, but in private window youtube works. What happened and what should i do to fix this?

I'm using this shortcut all the time and I recently found out it doesn't work as expected. From the Firefox documentation the ctrl+shift+t should re-open the latest closed tab, but this is not the case for me, it always re-open the latest closed window. Which behave exactly as ctrl+shift+n.

From my short research it's not possible to customize Firefox shortcuts without using an extensions, therefore I also don't know how to verify if the shortcuts have changed just form my browser/configuration.

I had a dedicated Firefox webpage popup yesterday that listed all my open tabs, tab history. I closed it before I noted the address and how I got there. I searched through my browsing history and I don't see it. I have never been able to access that page before. How do I bring it up again?

Thanks!

I have latest version of firefox on my windows 10 dell inspiron 7560 ... I have been using firefox for about 18 years now

system info - i7 - 8GB RAM, windows 10, one 128 GB SSD and other 512GB SSD

Since yesterday, it has been crashing after every 2-5 minutes; in troubleshooter mode as well...

I ran Windows RAM memory test, it turned out to be okay... I ran a Dell hardware test, it informed me that my fan is not working properly; though I doubt its the reason for my Firefox crashing

Below is one of the crashes in text - can someone help please?

On certain websites, I see that the background color of the new tab page replaces the default background color making the content unreadable, example:

If I browser this website: https://typespec.io/docs

Here's what I see (see the firsrt attached screenshot). Now, if I open the same URL in Private browsing, the background color changes too (see the second screeenshot). In the 3rd screenshot I'm adding the reference rendering, that's how I expect this website to render (Edge).

In the screenshot 1 and 2, the background color is exactly the same as the one used by the new tab page when I open a new tab.

Questions: 1) Why is that? 2) Can I change that?

Context: I'm trying to switch to Firefox (from Edge)
