When selecting "Open in Firefox" in the "What do you want to do with this file?" box or on about:preferences and then opening a PDF file on the web, instead of downloading the file to RAM and opening it with its online address, Firefox downloads the PDF to /tmp/mozilla_${USER}0 and opens it from there. This also adds it to the download history. I have set the about:config flag browser.download.start_downloads_in_tmp_dir to true so the files I just open and don't want to permanently download don't clutter my $HOME/Hämtningar (downloads) folder. I tried to first prevent that by selecting the default action to do when tasked to open a PDF, but that didn't fix it, so I set the about:config flag. Unfortunately, setting the default action stopped Firefox from opening a PDF inline without downloading it and I cannot find any option along the lines of "Preview in Firefox" (as described in this support article ).

I use Kubuntu 23.04 with Firefox from mozillateam/ppa apt repository, got update to FF 119 today (package 119.0+build1-0ubuntu0.23.04.1~mt1) and after the update Firefox stopped using system-wide installed fonts (either from /usr/share/fonts or from ~/.local/share/fonts).

So for example fc-list finds Gentium Plus (/usr/share/fonts), Iosevka and Junicode (~/.local/share/fonts) on my system: % fc-list -f '%{family}: %{file}\n' | rg -i 'gentium plus:' Gentium Plus: /usr/share/fonts/truetype/gentiumplus/GentiumPlus-Italic.ttf Gentium Plus: /usr/share/fonts/truetype/gentiumplus/GentiumPlus-BoldItalic.ttf Gentium Plus: /usr/share/fonts/truetype/gentiumplus/GentiumPlus-Bold.ttf Gentium Plus: /usr/share/fonts/truetype/gentiumplus/GentiumPlus-Regular.ttf % fc-list -f '%{family}: %{file}\n' | rg -i 'iosevka:' Iosevka: /home/silmeth/.local/share/fonts/iosevka/iosevka.ttc Iosevka: /home/silmeth/.local/share/fonts/iosevka/iosevka.ttc Iosevka: /home/silmeth/.local/share/fonts/iosevka/iosevka.ttc Iosevka: /home/silmeth/.local/share/fonts/iosevka/iosevka.ttc % fc-list -f '%{family}: %{file}\n' | rg -i 'junicode:' Junicode: /home/silmeth/.local/share/fonts/junicode/otf/Junicode-Bold.otf Junicode: /home/silmeth/.local/share/fonts/junicode/otf/Junicode-Regular.otf Junicode: /home/silmeth/.local/share/fonts/junicode/otf/Junicode-Italic.otf Junicode: /home/silmeth/.local/share/fonts/junicode/otf/Junicode-BoldItalic.otf

but when I try to apply the style `font-family: Gentium Plus`, `font-family: Iosevka`, or `font-family: Junicode` to an element, Firefox doesn’t use those fonts and instead in the element inspector I see Noto Serif is being used instead.

Before the update the appropriate system fonts were being chosen for rendering by Firefox.

I have Firefox 107.0b5 (64-bits) Snap for Ubuntu canonical-002 - 1.0 I use Ubuntu Mainline to update to newer kernels. Never had any problem doing that. I am now on 5.19.15. But when I upgrade to kernel 6 (which is now at 6.0.5) Firefox tabs crash. Reloading doesn't help. Each new tab I open gives the same crash message. I have to restart to get Firefox going again. So I removed kernel 6 and reverted back to kernel 5.19 and have no problems any more. But question, what is the problem between kernel 6 and firefox? Does anybody else experience this problem?

I have no other problems with kernel 6 with other programs or hardware or whatever, only firefox tabs crash...

Firefox beta release: 116.0b6 (64-bit)

On sites such as BBC.com, Youtube.com and Facebook.com I am not getting the normal cookie consent pop-up option which used to automatically show on opening the sites. Other sites are still showing the cookie consent option pop-ups. This means I cannot select if I wish to accept or reject cookies on several sites that used to allow me the option.

In checking about:config, the cookiebanners.service.mode is set to 1, which I believe this the correct setting for enabling the cookies consent pop-up option.

Is there any fix for the cookie consent pop-up not working on certain sites within the EU? I am not using a VPN or pop-up blocker. Tracking protection is set to Standard, cookies and site data are always deleted on closing Firefox and "Do Not Track” signal is set to always. Deleting all installed FF extensions has no effect either.

In other browsers on the same PC, Chrome and Edge, the cookie consent option does still work as it should on the sites mentioned. In Firefox it doesn't.

This is only happening on one PC. My latop has the same FF beta build installed and is not showing this behaviour, it still automatically shows the cookie consent pop-ups when visiting sites such as BBC.com, Youtube.com and Facebook.com.

When I try to log into my website - https://huppbrian.us/tsc-admin - with Firefox Developer 111.0b8 (64-bit), get the following error first time every time... Error: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress. If I try again without making any changes, I'm able to log in fine. I've tried playing with the protections settings, but haven't found the magic pill to fix this yet.

Recently, I've started noticing these quick action tiles in the URL drop-down menu (I've attached a screenshot). There's a help icon to their right, but it just goes to https://support.mozilla.org/en-US/kb/quick-actions-firefox-search-bar?as=u&utm_source=inproduct which is a 404. I found this bugzilla bug, but I'm not 100% sure on how the versioning works (even after consulting Wikipedia). The bugzilla entry mentions it's fixed on 105.0a1. I'm using 105.0b6 of the Developer Edition.

Firefox Developer Edition - Developer Console is killing my productivity. It started opening in Full screen mode about a week ago and will not exit full screen. I have to F12 and exit developer console. This is a major issue because, I work with the console not docked. Docking blocks my productivity. F11 only puts it into some very weird outline mode where all I see is a rectangular grey outline on my full screen. If I click on it, it repaints the console in full screen. There is no option to drag and expand or contract. Nothing. Nada. Please help. This is my primary browser, er -was my primary browser. I'll continue to work around it until my patience is completely exhausted. Almost there now.

Sorry about the terrible markup on the screenshot. It's hard to encircle a big gray full screen empty frame. Thank you.

A required site I need to use for work has a popup dialog box that never works right in Firefox, the popup dialog shows up as a blank box or doesn't popup at all in Firefox. I must print what is supposed to be there in that dialog box. It's been like this for a couple of years now. I've tried everything imaginable and searched high and low for the fix. I have had this particular site set as an exception to popups blocking, and then I also set it to have all popups unblocked. Still doesn't work either way. I have to use the site in Brave instead, and it's the only way I can get what I need done. I used to love Firefox SO much, I used it exclusively. But it has undergone some unpleasant changes recently, such as hiding my open tabs on my iphone. Because of these issues I find myself using other browsers more and more.

I am currently unable to view any file activity or ownership information in Google Drive in a shared folder. I have tried the following troubleshooting steps:

• Quit and reopen firefox
• Relaunched firefox in safe mode/extensions disabled
• Cleared cookies
• Tried in other browsers (works in Librewolf, Brave and Chromium; doesn't work in any Firefox browser (Nightly, beta, standard)

My preferences are set so that "When you open a link, image or media in a new tab, switch to it immediately" is OFF. Therefore most of the time when I Cmd+click on a link, it opens on a new tab that loads in the background. This is what I want.

However, some websites break that behavior. 2 high-profile examples:

• In Google Docs, if a piece of text links to an URL, clicking on the text shows a small window with the URL. Cmd+click on that URL opens it in a new tab, and takes me to that tab.
• In Facebook Messenger, if I Cmd+click on a chat, again the chat opens in a new tab and I'm taken there. Additionally, the original tab activates that chat.

Interestingly, in both these cases, I get the right behavior if I right-click on the URL or in the chat and in the contextual menu choose "Open link in new window/tab/container tab": the new tab stays in the background.

So my question is: does anyone know of a way to always make cmd+click behave just like "Open link in new tab", no matter the website?

I'm on Firefox 115b4 on macOS, but this has been like this for years at least.

I'm having an issue with a particular text field. When entering any text into said text field, my CPU will shoot to 100% usage on some cores, hang for a bit and then print the text after a few seconds. I have an Intel 13900k @ 5.5ghz.

I can't provide a link to the text box as it's a WordPress CMS on my local machine. This issue does not present itself on the competitor browser.

A few troubleshooting steps I've taken:

• Re-install Firefox
• New profile
• Disable all extensions
• PC safemode + Firefox safe mode
• Tested dev/nightly/stable (I'm using BETA daily)
• Disabled accel

Hopefully I'm able to have an expert look at my profiler to help determine what the issue is. I'm not knowledgeable in this area unfortunately. https://share.firefox.dev/3s60ISV

Thank you.

Firefox 114b5 does not remember form history. I have tested two different websites.

I have form history enabled - see attached browser_settings.png. Attached is a screenshot of the moz_formhistory table in the formhistory.sqlite file.

What do I need to do to enable form history on all websites?

Hi Today I updated Firefox to version 106.0 and I can't get rid of the "arrow button" from top right (screenshot attached - near the minimize button, I marked it). The function of this button is clear for me - tabs management. But I can manage my tabs without special button for it. I want to remove it. I tried right clicking on it, but the "remove from toolbar" option is unavailable. I tried to customize toolbar, but it won't work either (I can't take it from te toolbar).

How to remove this button?

Hello, I'm currently running firefox developer edition and i'm facing a weird bug: When firefox is started, opening a web url from outside of firefox window does'nt work and display error message: "Firefox is already running but is not responding...". It expects that i close all instance of firefox instead of just opening url in a new tab.

Do you have any idea?

I'm working on version 105.0b2 with two profiles on an ubuntu 22

Discord hyperlinks will no longer open when Firefox Developer Edition is selected as my default browser. They open fine in both Firefox, Microsoft Edge, and Google Chrome when selected as Windows 11's default browser. When selecting my default browser it would show 2 instances of Firefox Dev but after uninstalling then reinstalling it there is only one instance in the default app list. I'm not really sure where to go from here. Maybe this is an issue with the latest version of Dev Edition or is this an issue with my Windows?

Thanks

After updating to Beta 122.0b3 (64-bit), the active tab is now highlighted with a simple white outline instead of the coloring surrounding the address bar. My selected theme has not changed, and the same goes for all of my extensions. I could not find this change in the 122.0b Release Notes.

If this behavior is intentional, is there any option to return to the previous behavior (including in about:config)?

Noticed yesterday but not as prominent, firefox suddenly steals all window focus, trying to do anything in any other window is pushed into firefox no matter if it is minimised or in another workspace. I have tested this in a clean install along with a clean profile. Bitwarden and other windows seem to act weird when they are interacted with.

This all works well and good on b8 and stable. I am using wayland (Ubuntu 22.* default), but xwayland is available.

When Firefox asks if I want to download an update and I agree, soon after that but not right away it stops working - on every new page it says "We need to restart to finish updating" <- This last bit is VERY annoying. Is there a way to keep FF working in such situation? I usually have 3 FF profiles running, about 10-20 tabs each and when it suddenly does this - I can restart them all but when it is suitable for me.

The only solution I can see so far is disabling updates via group policies (which is not well documented, where do i put this policies.json on Fedora? need to google that).

Any other ways to keep updates and FF running until I decide when to restart? Thanks.

I am attempting to build a script (extension) that will open any focused page in Firefox with Microsoft Edge from the context menu. The intention is to utilise the existing microsoft-edge URL Protocol in Windows instead of a native client.
