Firefox Support Forum

I hear that enabling .has() for CSS in about.config in browser level is done for testing purposes. Will it be enabled by default in future? Is there a way to do it in our site programmatically

I'm using Firefox 112 on Windows 10. The toolbar contains icons for several extensions that I don't want to see. I click on the >> menu and then Customize Toolbar. That opens the Overflow Menu. It says, "Drag and drop items here to keep them within reach but out of your toolbar." I try to drag one of those extension icons onto the Overflow Menu. It won't go. The dragged icon picks up a circle with a line through it, indicating that this is not allowed or not working.

How can I use the Overflow Menu as advertised, to remove unwanted extension icons from the toolbar? Or is there a good workaround?

For the last month or so I have had problems with Firefox using too much CPU, too much memory. This is not long after I have restarted. It soon gets so bad that there is a 3-6 second delay in anything I do. At this point I am going to have to stop using FF as it is too disruptive. Cannot place any other system changes.

I have two RHEL 7 hosts, one is supported by me and one is AWS. Firefox is the default program to view an html file, so running gio open <file>.htm should either launch firefox and display the file, or if firefox is already running, it should open the file in a new tab in the running copy of firefox. This works fine on the host supported by me. However on the AWS host, the first file will launch firefox and display, but subsequent files, launched from the same xterm, result in "Firefox is running but not responding...". I have searched and found suggestions about the profiles, so I created a new profile file that is identical to the one that works apart form the names. I found suggestions related to .parentlock, so I tried removing that. That resulted in a new browser being launched and a new .parentlock file being created, so that didn't help. Both hosts are running the same version of firefox, installed using rpm updates. I have tried the MOZ_DBUS_REMOTE and MOZ_NO_REMOTE environment variables, but they didn't help either. I looked in about:config at the various ..newwindow.. options, and those are the same between the two hosts. I did notice that opening a new tab in the browser in AWS takes longer, but I don't know if that is relevant. Any suggestions for how to have the currently running copy of firefox display multiple local html files would be appreciated.

With the latest version 112.0.2 NordPass stopped functioning properly. Will not autofill. This happens on all 3 of my computers 2 are windows 10 and a win 7). Other browsers (Edge. Brave etc) work fine. I have cloned backup of system disks. I booted from a backup drive, which has previous version of the browser. and NordPass works fine. I tried several troubleshooting steps: turned off all other extensions - complete uninstall of NordPass and did an install - lowered security protection - used CCleaner & Privazer to clean system after each step. Any help would be greatly appreciated. Firefox is is my default browser.

Why does Firefox unpin itself from taskbar ? I pin the app to the taskbar then open the browser; when I close the browser, the app unpins from the taskbar. Near as I can tell, Firefox is the only app doing this; all other apps I tried stay pinned after closing.

I accidentally entered the wrong age (5) when setting up my Firefox account using Firefox so now I cannot login on Firefox (only Chrome). I keep getting the message "Cannot create account. You must meet certain age requirements to create a Firefox account." Is there any way around this?

When i use a link to an Excel Workbook stored in a GitHub repo the downloaded file is only 6 Bytes - and consequently rubbish. When I do exactly the same thing with Edge or with FireFox or Edge on another computer the downloaded file is complete. I've cleaned up FireFox but it didn't help.

Hello,

Recently I rebuilt my Widows 11 laptop, which meant that I needed to install Firefox again. I did this and signed into to sync all my add-ons again. The add-ons installed without issue, however the icons for them are not displayed on the tool bar. I can access them using the jigsaw icon, but this is is less inconvenient that accessing the add-on directly.

I then reset Firefox in case it was a glitch and signed in again to allow the sync to reinstall the add-ons. This time only the Privacy Badger icon made it onto the toolbar. Again I can access the add-ons using the jigsaw icon.

I have tried to add the add-ons to the Customise Toolbar setting, but they do not show up in the list of things that can be added.

Firefox version: 112.0.1 (64 bit)

I have attached images to show what is happening. Is there anyway I can force the add-on icons onto the toolbar to make them more accessible?

Thank you

I have no access to all my bookmarks and the damn backup folder is empty, what kind of trash is this, I need this for my work and not even the search history is avalable, no more damn firefox, let me know if there is any way to get back that bookmarks and browser data since I have no way of retrieving any of the cinfidental accesses I need to perform my job

Recently I got a Mac computer and I installed Firefox in it. I can't find "About Firefox" in Application Menu.

How to show it in Application Menu like Windows and Linux?

What configuration setting do I adjust if I want to change the font size of only the tabs and toolbar text, not the text of the window / body (managed with Windows' "Make text bigger" option)? I've made the text of the tabs and toolbar large enough for my taste, yet that same setting make the text for everything else in the browser way too big. I'd rather not download a third-party extension as the solution as that implies third-party data gathering. Thank you.

Using Google with Firefox I type search terms then press 'Return'. Instead of displaying search results Firefox starts a new line in the search terms box. This has only just started....

I'm having a problem sharing websites with others via, for instance, Signal. Telegram, WhatsApp or a social medium. There used to be a share button in the toolbar, but this I cannot find anymore. At some time there were also the three dots in the address bar that dropped down a menu for the page, which included a 'share' option. These dots seem to have vanished. Also I vaguely remember that the "share" function was also in he tab context menu once upon a time. However dropping down that menu does not reveal any "share" function presently. Then there was, if I remember correctly, the possibility to click the File menu at the top of the screen and then click on the Share menu item over there. But also there the "share" function seems to have vanished. I also looked in the settings menu, to find if there is a setting there which switches on or off the sharing function. I could not find such a setting. In short, it seems that I am horribly overlooking the "share" function. Please help me find it. Thanks. (Firefox 112 for Manjaro Linux)
