Firefox Support Forum

Hello! I love firefox, but latest versions have a feature that disturbs me a lot. I’m using more than one screen with different dimensions. Then I move firefox window from one screen to another, firefox automatically adjust his window size accordingly. Please, tell me, how I can disable that feature? Thank you!

We want to customize the look & feel from firefox. We are using the userChrome.css file.

In the past we used the following entry to hide the menu bar in Firefox:

1. toolbar-menubar

{display: none !important;}

Now on Firefox 78.6 (ESR Release) this works different. The menu bar is hidden but the close Icon (and the minimize/fullscreen Icons) are hidden too.

Is there a way to hide/disable the menu bar but keep these icons/buttons?

In the age of COVID and a switch to more remote work the dependency on online meetings has increased. The company I work for uses Google Apps for Business and has been using Google Meet for a long time, and I've never had any problems with it not working. Recently though, when I join a meeting using Firefox, nobody can hear me and it appears Firefox is not able to access my microphone. Here's what I've done to test:

1. Reviewed Windows 10 settings to make sure microphone input slider is up. 2. Checked other browsers, running Google Meet using Chrome works fine. (Note: everything was working before and I attempted to use Chrome to try out changing backgrounds. It seems like this is when my problems with Firefox began) 3. I've tested my microphone using https://www.onlinemictest.com/ initially it didn't appear to work, but if I tap on my laptop screen near the microphone I see lines showing activity, but it won't pick up voice. Using this same tool in Chrome works as expected. 4. I tested using Private Mode - Same results. 5. I tried clearing the startup cache - same results. 6. I tried using Safe Mode - same results. 7. Refreshed Firefox (using Troubleshooting Information screen (Refresh Firefox...)

I'm at the end of my rope trying to figure out what's going on, and why it only appears to be Firefox that's having a problem. Other apps like Zoom, and recording video using just the webcam on the computer also works fine.

Any help in getting this figured out would be appreciated. I try not to use Chrome if I don't have to, but switching to Chrome so I can join web meetings is a real pain.

I've had "HTTPS-only" turned on since it became available in a recent Firefox update, but its behavior seems very odd. I frequently get the error window that says HTTPS isn't available and gives me the option to cancel or proceed to a non-secure site. But most of the time, the page that opens when I click to proceed is indeed an https page.

Why is the Firefox module seeing these pages as non-https and not just opening them as they are?

Hi,

I'm trying to disable the media popup in windows 10, which appears when you lower your volume or skip a song or anything (see added image). I have a brand new pc and on my old pc i was able to fix this easily by doing this: go to about:config and change this: set media.hardwaremediakeys.enabled from true to false.

I did that now, with my new pc as well. But i just does not work, i restarted my browser and pc after changing it, i set it back to true and back to false again, it just will not work.

I googled this issue, but the only solution i find, is what i exactly the thing i described above, nothing else.

After updating Firefox forgets that I want .pdf files opened with Windows standard application instead of downloading them. Can Firefox be told to remenber my preferance?

Hello there,

I am using Firefox 84.0.3. When I type in the search bar suggestions show up that's ok but I feel a little awkward when I have to press Up/Down arrow to focus items in search suggestion list. Instead want to use the Tab key. If i want to change the search engine i can use Alt + Up/Down arrow.

Thanks.

I tried omnibox with the following code from MDN. When I trying, I temporarily loaded manifest.json from about:debugging. This worked in a normal browser, and typing cs a show a some suggestion.

However, this suggestion feature is not working in private mode. This did not change even if I allowed it to run in a private window. How can I get the omnibox suggestion feature to work in private mode?

Hi, I use FireFox (edit - 82.0.4 from LM repos) for my browser when using Linux Mint (I use it on WIn10 as well but this query is specific to LM). I use ClamAV for virus scanning. ClamAV has found Js.Coinminer.Generic-7132237-0 in /home/username/.mozilla/firefox/puhh983l.default-release/extensions/adblockultimate@adblockultimate.net.xpi I've searched and found some mention that it might be a false positive but nothing confirming that info so far from my searching. What have I done so far: Done a fresh reinstalled of ClamAV following the ClamAV install procedure. Checked ClamAV is up to date by checking log files and latest available on the ClamAV website. Done a fresh install of FireFox Reinstalled add-ons one by one. ClamAV only finds the Coinminer once Adblock ultimate is installed/added. I'd like to keep Adblock ultimate as it does what I want it to do easily and efficiently but am happy to remove it to avoid the coinminer (if it is a problem and not a false positive) Can you help or have any advice. Thanks

Hello.

Flash files stopped being supported on January 12th. I am a user of a site where "mini chat" uses swf files as the sound of a new message. Since firefox does not play these files, is there any option to notify (e.g. beep sound) that a site has tried to play such a file? maybe some kind of addon?

Or is there a way to make swf files work only on this page?

OS: Catalina Model: iMac (27-inch, Late 2013) (tested on Macbook pro 2018 and 2011 too) Firefox: 84.0.2

Expected functionality: First expand the window to full screen using the green window control. The expectation is that the tab and tool bars will eventually hide, however firefox implements this - by sliding up when scrolling or just sliding up and autohiding after a short time. The tab bar should then reappear when the mouse move to the top of the screen.

Functionality Observed: Tab and tool bars never autohide. They are always there. The only way to that they hide is when a video (YouTube, Netflix) fullscreen controls are selected. Otherwise they are there on every page and that is not the expected behavior. Id like every page to autohide the top bars (similar to what all tablet/mobile device browsers do).

Settings verified: browser.fullscreen.authide= true (see image). Hide toolbars is checked (see image).

Issue I have found posted on this do not provide a concise reason as to why this behavior exists when all settings are properly set.

Why is it that Firefox changes the default application for viewing PDFs?

I have several machines with Firefox installed and I have one that constantly changes the default PDF viewer from Windows Default to Save - every single day. Very annoying.

“连”、“设备” are Microsoft YaHei(MSYH), but the others are other fonts which are not on my computer, and although my settings are zh-CN, my language pack is zh-CN, my Default Font is MSYH, the bold characters are JAPANESE STYLE CHINESE CHARACTERS. Maybe it is because in your font-config, ja-JP is former to zh-CN, please fix it.

Hi, I am using Parrot OS and I cant scroll or use any touch gestures on Firefox, it just highlights the text. Chromium however works fine. I would love a fix to this issue. I have tried the steps below, any help greatly appreceated. J

about:config in firefox to set dom.w3c_touch_events.enabled=1 (default is 2). edit /etc/security/pam_env.conf and add MOZ_USE_XINPUT2 DEFAULT=1 reboot and restart firefox

Is there a way to change the default keywords for the bookmarks (*), history (^) and tabs (%) search shortcuts in the address bar?

Is that possible by changing an about:config setting or using an add-on?

In my case, the default keywords are really inconvenient. With a German keyboard, the ^ character does not appear directly after pressing the key a single time. To enter the keyword for history followed by a space into the address bar, I have to press the ^ key and afterwards two times the space bar on my keyboard. Other users might not know the fastest way of doing it and require even more steps (f.e. pressing ^ twice, then deleting one ^ character and pressing the space bar once).

In general, it would be useful to be able to adjust these keywords to the users' own preferences.

Helo there, we use an WebAPP in our company and we used some shortcuts in older FF version for Help-Pages. After Firefox Upgrade ESR 60.2.2 -> Firefox ESR 69; we can no longer access our shortcut keys for ex. Ctrl + Shift + F was used for popup window for help-page -> JS Event

ui.key.contentAccess is set to 4 -> pref("ui.key.contentAccess", 4);

any advice for the new FF version?

Best regards Adam
