Firefox Support Forum

I've got FF set for https-only. But sometimes it will tell me no https is available but when I go to the site anyway it is https.

Is this a bug or is this something in my settings?

Using Mozilla Firefox 108.0 for Ubuntu canonical 1.0 on Ubuntu 20.04.

Thanks.

I have deleted my bookmarks with the Bookmark manager, but where are they now? I cannot find them in /trash and all of the *bookmark* files on my laptop are miniscule (like 127 bytes.) The json files are no better, when I imported previous bookmark files they were empty.

I use firefox since I go to college. When I got some problems, I try to check firefox use what to pick folder? I use Manjaro Plasma. I find chrominum use kdialog. But firefox looks not though both use gtk3 as UI

Firefox choose folder got wrong when use a USB HDD

I haven't used my microphone in Firefox in years. I tried today, logged into Google Voice, which tells me it can't access the microphone. I set permissions in Firefox's settings. I turned up all the mic settings in alsamixer. I tried https://mdn.github.io/web-dictaphone/ , recommended in another thread here, and it doesn't record either. I can use the microphone outside X, with sox's rec. I also can't record a new greeting in Google Voice.

Firefox 100.0.2 , Linux, Slackware 64-bit, all packages updated this morning.

When clicking on a link to an .mp4 file, Firefox navigates to a builtin video player, streaming the remote video file. When Firefox is unable to stream or display a file (as is the case with .mkv or .txt for example), it is downloaded instead.

I simply want .mp4 files to be downloaded when I navigate to them. I tried setting `media.mp4.enabled` to `false`, and that worked, but it also disabled most embedded media players.

So, a preface. I rarely used this PC of mine, and thus the Firefox is rarely used as well. When i installed it, i turned on the option 'Open previous windows and tabs'.

Then, once I opened up some kind of offline documentations from Libre Office or Latex, which opened in Firefox. You know, the one where there is no tab appeared, and it just seems like a single pop-up window. I closed it without thinking.

Long enough, i forgot about that and opened up Firefox only to be met with that docs again. Okay, i closed it. But Firefox always started in this kind of pop-up window style ever since (attached). Changing the preference, even deleting the profile doesn't seem to do a thing.

Any recommendation to return Firefox to its original set?

I am experiencing problems when using Duolingo, which is highly interactive.

This same problem was highlighted in Version 95.0.2 from a Windows user. The waveforms on System Monitor/ Resources are the same.

I am using Fedora and have 16GB ram. Have just ordered another 16GB ram, but think this problem is so severe that no amount of ram will fix it.

When entering full screen mode it's only inside selected window. Also affects youtube player. Pictures when in full screen mode (using F11 key): https://imgur.com/a/gp3yqCC

I was using Ctrl+K on some websites to do things like site-specific search, task bars, and so forth, but recently Firefox started capturing it for focusing on the search/address bar (https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly#w_search).

Is there a way to unbind `Ctrl+K` in Firefox?

i am using Firefox Snap version 103.0.2 (64-bit) on Ubuntu 22.04. Whenever I try logging in to twitter, It shows a blank screen after I press login button after entering the password (Image is attached). I can login to other browsers I have installed on my laptop.

I have tried removing cookies of Twitter.com several times and even reinstalled snap version but the issue is still there. Any fixes for this? I can't keep switching browsers just for using twitter.

Hello,

After installing Firefox (103.0.2) on a clean install of Manjaro (21.3.7) Gnome (42.4), I started noticing that mouse hover effects such as highlighted tabs, UI of a video-player appearing etc. are delayed after my PC exits hibernation (I am not sure if that is the only cause and if that really IS the cause). Weirdly enough the select menu I used to answer the "Which topic best describes your question?" question to create this post experiences no delay in highlighting the hovered element. Relaunching Firefox fixes this issue temporarily.

To be clear this is no performance issue since everything except mouse hover related interactions are fluid.

Thanks for helping out

I'm trying to install Firefox on a Chromebook. I've done this successfully before. Using the instructions in the Mozilla page https://support.mozilla.org/en-US/kb/run-firefox-chromeos?utm_source=www.mozilla.org-firefox-browsers-chromebook&utm_medium=referral&utm_campaign=seo#w_installing-the-firefox-desktop-browser-with-flatpak

But the command in the terminal window sudo bash -c "$(curl -fsS https://raw.githubusercontent.com/mozilla/sumo-kb/main/run-firefox-chromeos/install-flatpak.sh)"

Is giving me the error message curl: (22) The requested URL returned error: 404

Any advice would be appreciated! This is a fresh ChromeOS environment since I just did a factory reset so everything should be clean, and with latest OS version.

Thanks

My firefox suddenly became very slow after an update. On each web page I have to wait maybe 10s, and nothing happens, and after that all is ok (really fast). Safe-mode didn't help. Thanks, Piero

I'm currently running Firefox v 112.0.2 on Linux. I've had a theme installed for a while now that I really enjoy. It's a minimalist theme I found on github and then I topped it off with some colors that suite my desktop theme.

The ONLY issue I am having is with the dropdown menus. I can't see any of the list items and I cannot for the life of me figure out where to modify these colors. Searching has only gotten me more confused.

Photo is attached. I'm hoping that changing the text color here is an easy fix. The colors are all fine in other dropdown-ish menus, like bookmark folders for example.

Thanks in advance for any advice.

I am not able to download any kind of file, from any kind of website to my disk. I am able to select open on the download dialog, and this will open the file and save it to the temp directory firefox uses for this function, but this does not save the files to disk/the download folder like I want to. I am unable to "Save image as..." as well, since this is considered a download. There is no record of these downloads even being attempted in the download history.

Related to some personal SVG project files. Which are relative large files (containing lots of generated paths and other data).

On the largest of these files I spotted that some general svg-viewer failed with a "XML parse error: cannot load more than 200.000 XML elements" error message.

The same file, when viewed in Firefox (114~, Linux, Mint), also developed some odd hiccup that did not make sense. Unless ...

Is there a similar limitation active in Firefox ?

- I tried to see if "Inspect>Console" gave some potential related message on this. But spotted nothing out of the ordinary. - Searched developer.mozilla.org for any related svg data. But could not find any. - After ditching some data in the effected file, unrelated to the hiccup part, the hiccup disappeared. Suggesting I did hit some svg limit in Firefox. - File size: ~26.5MB. Number of elements: Other than more than 200.000, unknown at this point. (not sure how to count them at this moment either)

Firefox says I need a video codec to play a video (that is aparently somewhere on the page). It does NOT tell me what video, what video format, or what codec I need. How do I find out what codec I need?

Hi, I have a widescreen monitor and I really like utilizing, well, the width of it. But for the life of me I cannot take out the extension icons from the little jigsaw puzzle. For instance, I'd really like Ublock Origin to be right on the toolbar and not click through the jigsaw icon. I tried setting extensions.unifiedExtensions.enabled flag to false but it did nothing.

The issue appeared about two days ago. On the page https://index.hu/ the left click is not working from firefox. This is the most popular news site in Hungary. I also experienced the issue on other sites.

It is working fine from chrome and chromium. The issue is appeared on linux and windows 10 machines as well.

I tried to clear the cache but it does not help.

Please fix this ASAP or I have to delete your browser.

As you can see from the screenshot I don't have the new tab button (+), I've seen other users had the same problem in the past and the solution was restoring it from the customization page, but I can't find it there neither.
