Firefox version: 119.0 (64-bit) OS: Windows 10 Home 64-bit

Hello,

Whenever I open a local HTML file, Firefox tab will crash. This happens if the HTML file size is big (>4MB), smaller file doesn't crash.

I've tried opening the file on Chrome, it doesn't crash and open just fine. So it seems like this is a bug with Firefox.

I've uploaded the HTML file if anyone wants to test: https://www.mediafire.com/file/ipmu7ugrd2vvelr/LICENSES.chromium.html.zip/file

Thanks

Hi, so here's the issue I have: Lets say you have 20 tabs open where the "tab scroller" becomes active and tab#17 has a video, if you enter & exit fullscreen on that tab then tabs #18-20 will slide to the right and go out of sight. This is quite annoying as I'd prefer all tabs on the right to be visible until I manually scroll to the left.

I tried googling for about:config or userChrome.css solutions but couldn't find anything, does anyone have any ideas on how to change this? Thanks.

There is one domain that I get a "server not found" error for even after doing many things to fix it including everything here, https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can#firefox:win10:fx119, checking blocked URLs in the registry, running malware checks, safe mode, reinstalling FF after removing all FF folders from my system.

Before I did a completely clean reinstall, disabling the Open H264 codec (see attached screenshot) would allow me to access the site. But thinking it was needed, I did the clean reinstall. Now disabling it does not allow access to the site.

So far, I have not found any other websites with this problem. It's a .edu domain which happens to be the one I work for! What else can I do?

I tried to watch a youtube livestream today and it failed to play. Non-live videos on youtube are playing, even the same videos watched as VODs after the stream ends, but the livestreams are providing "Your browser can't play this video" errors.

Simultaneously, I'm noticing that some videos on Reddit (such as embedded tiktok videos) are stuck with a circling ring and won't play. At least some of the same videos will play on Tiktok (when I can find them).

ALSO, when I try to watch videos on my Nebula subscription, I'm getting a "This video could not be loaded: 4" error code. ANY video on Nebula.

What the heck gives?!

Why does Firefox cut off the bottom of the score banner on ESPN website? (See screenshot)! This question was asked 5 years ago and was never really answered correctly https://support.mozilla.org/en-US/questions/1189999

(I tried the suggestions made there, but the issue persists), so please don't refer me to that answer.

As you can see, MS Edge has no issue with it, nor does Opera.

Since the last couple updates Firefox is NOT allowing my Password Manager to fill in logins, usually after clearing the cache which I do once a week, at least. Why is that?

Second: Your browser is being managed by your organization. That is not true. There is no organization, there never has been, I'm retired and this is home use desktop running Windows 10 and no one but me has EVER managed Firefox and I've used this browser, though no longer as my default, since it first became available. So why does it think anyone but me controls anything about it?

I'm not very computer savvy but I followed a website a few months ago to edit Firefox so it'd default to dark mode. I think I went in and edited source code? I can't find the instructions anymore but I'd like to revert back to the original setting. How do I do that? I tried to refresh Firefox but it's still coming back with some websites in dark mode and some not. Please advise!

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.

Hello,

Sometimes, when I click an embedded/hyper link within Firefox, say I tried clicking a link provided after I google searched something, the tab itself would hang for 10 seconds before it would begin loading the site. When I say "hang", I mean that the entire tab becomes unresponsive to my clicks, I can't refresh the page, I couldn't change the address bar to a different link (it would allow me to manipulate the address bar, but the browser wouldn't reflect on that change, instead just going to the link I had clicked before the hang after the 10 second delay) and my mouse just stays as one sprite/disappears all together (when on the tab).

I find that this isn't a full browser issue as I can easily just start another tab and try there, but this issue is prevalent in that it randomly hangs any one tab I'm using for 10 seconds, and it's not just with Google.

I've identified that it isn't an extension issue or a different tab being used (tested in troubleshoot mode), nor an accessibility issue (as far as I know). I've disabled both my firewall and antivirus temporarily and it still occurred.

It's gotten in the way of a lot of work and I haven't been able to find anything regarding this exact problem on the support site. I've been dealing with it since my first installation of firefox (a few months ago).

When opening a file from another drive, I get an error: Access to the file was denied

I know this can happen on the Snap version, but I have Firefox installed from a deb!

Hi,

After updating Firefox to 116.0.1 my tabs keep randomly crashing. I get some crash reports *occasionally* - meaning not all crashes produce a crash report - but I'm not sure what to do with them, they seem inconclusive. The last report (not for the last crash, though, which didn't produce any report) is bp-3334b934-58b5-4226-887a-235300231117

I have a Logitech mouse. I've used it with both Brave and Chrome problem without problems highlighting text. But the highlight function doesn't work properly with the mouse in FF.

I can double click and highlight a paragraph. I can highlight a single word with no problem. But when I try to highlight a series of words or a full sentence, I can't. Either it highlights but when I try to Copy the highlight disappears. Or when I drag the mouse to highlight it won't highlight at all.

Since the issue only occurs in Firefox and not other browsers, there has to be something in Firefox that's causing this; or some conflict causing highlighting not to work.

I'd be grateful for any ideas how to fix this. It's driving me crazy.

When I go into fullscreen, by any means (F11 or dedicated button next to zoom settings), only the firefox toolbar disappears. The window taskbar stays there. Issue is not present on other installed browsers.

I tried: - Troubleshoot mode - Tinkering with windows accessibility settings for Firefox - On troubleshoot mode, Individually flipping these configs (+ refresh): - - browser.fullscreen.autohide - - browser.link.open_newwindow.disabled_in_fullscreen - - browser.link.open_newwindow.disabled_in_fullscreen - - widget.windows.fullscreen_remind_taskbar

So I opened firefox today and it updated and after it updated my tabs are now like a 4th of my screen (see screenshot) and also the bookmark bar is now white where I believe it was grey or black before. I am not sure what to do to fix this issue.

Hallo there, somebody knows how I could on my side the log out timeout of any website where I have a login some longer? I am using a forum (ubuntuforums.org) quite often and after only few minutes I am logged out, I have to login again. This is annoying. I would love to manipulate such logins so that the site thinks, I just logged in and does NOT log me out automatically after x minutes or seconds.

Is there such Add-On or setting? I guess its the expiration date of session cookies, isnt it that, where these log outs are calculated? Thanks for hints, I am on Firefox latest (119.0) on Windows and Ubuntu. frank
