In Firefox, my instructor and student grade sheet no longer displays the horizontal scroll bar to bring more data extended off to the right of the page into view. I have an image attached where the scroll bar should be present. This begin in May sometime, and I'm not sure how to fix. I have tried re-installing fresh a few times, and removed any custom settings that might have been in place. Any and all help would be VERY appreciated as one of colleagues is super frustrated and I would love to find out an answer for both him and myself.

i own a macbook and have recently switched from chrome to firefox- in my mac settings, it hasnt given firefox the permissions to use my microphone or camera. it doesnt show up the usual list to be able to allow the permissions. i've enabled microphone and camera permissions for the websites i want through firefox, but i cant even unmute myself. i think i need firefox to give me a popup and ask for microphone permissions, but it hasnt done that- and even if it did, i think it would show up in the list for allowing permissions through my mac settings (it shows applications that have requested for microphone access).

Hello, Few days ago I noticed that Firefox started complaining about self-signed certificate issues, although I added my CA certificate to authorities months ago. It worked without any problem, but now I'm unable to open any of my internal sites anymore.

I tried to open a random site in Chrome, but the same issue. So you immediately will say the is in the certificate, but wait. I have few VMs running on Virtualbox, so I decided to test in there. Guess what, no issues at all. I tried in Fedora 25 (the Firefox version is below 100), then tried Windows 100. Both worked. Then I decided to update FF to the latest version, guess what - it broke again =]]

So something has changed, but I really don't have a clue what causes the issue. I attach the screenshot of detailed CA view from Firefox.

hey folks,

since today firefox wont load any websites out of troubleshoot mode. not even settings/ about:config. if i open a page in a new tab it just stays blank and nothing is happening.

in troubleshoot mode i turned off hardware acceleration - nothing changed after restart. i updated the runtime file "Visual Studio 2015, 2017, 2019, and 2022", which is suggested in different help-posts, i deactivated all addons, i created a new profile and also tried an imported one from eralier today - so far nothing has worked.

i also reinstalled firefox with version 99/ version 101 two times, after i cleared %APPDATA%-data.

im also just using windows defender as antivir.

please elp, i'm out of ideas.

Been using Firefox for long time on a Win10 machine. Motherboard failed. Saved the C drive. Question is how to move bookmarks (profile files ?) from the old C drive to the new Win11 computer? I tried moving the profiles over from the old C drive to the new computer but Firefox would not recognize them and shutdown. Restored the Win11 files and Firefox is again happy.

It's quite annoying to try to type a capital F using Shift F but end up with developer mode.

I tried in privacy mode and this still occcurs, so I think it's not something my add-ons do.

Is there any way to disable this feature?

Hi, my Firefox on Win10 doesn't work, I've been forced to go back to Chrome. After a crash in Win10, Firefox doesn't work anymore: it opens, be it launched by me or by other programs, but it just sits there, blank, doing nothing. It is impossible to interact with menus and everything. Task Manager shows two open instances of the browser, using RAM, but the browser doesn't do anything. It doesn't "crash" and it doesn't freeze, it just stays like that. If I quit it and try opening it again the PC tells me it's open already, and Task Manager shows a couple instances staying there after quitting it, as if it stayed stuck. I tried resetting it from the Apps settings of Windows, but nothing happened, I tried uninstalling it and then installing it again, but nothing happened. Restarting the PC a couple of times changed nothing. In the end, I had to go back to Chrome and even put it as default browser because all programs were calling up Firefox which stayed unresponsive. Anybody knows what I should do in a case like this?

I routinely record short screencasts with Kazam, and I can't watch my own videos after posting them on sites like GitHub because Firefox says "Video can't be played because the file is corrupt". Or for example when I upload them to sites like ezgif to convert them to a GIF, which works just fine because, well, the file is not corrupt. Other browsers like Chromium play them just fine.

Apparently the "OpenH264 Video Codec provided by Cisco Systems, Inc" is properly enabled in my system. This has been happening to me for months or years, but only today I decided to open a thread here.

There are two things here:

1. Firefox can't play the file. I'm sure there's some sort of misconfiguration on my side, or bad defaults, or a missing plugin, or similar. 2. Firefox shows a misleading message. The file is not corrupt! The root cause is something else.

Any advice on how to fix the first one?

Hello. I just closed by accident my main window so I restored it, but it apparently lost all the container data and restored all non-pinned tabs to the default container.

Is it normal, is it a bug or is it a yet-to-be feature?

It feels like a bug because pinned tabs (which were not present/open in the secondary window that stayed open when I accidentally closed the main one) where duly opened in their respective containers.

When I add a new bookmarks I can see them in "Recent labels", but not in "Other bookmarks" (the last one in that folder is of the 20th of February 2022), so I can see only my last 10 saved bookmarks from the 02/20/2022 since now. The bookmarks are surely saved, because if I try to delete one fromt the "Recent labels" another one less recent appears, but only in the "Recent labels" folder and not in the "Other bookmarks". So, what I have to do to see my saved bookmarks not present in the "Other bookmarks" folder, but not so recent to be visible in the "Recent labels"? Thank you!

I have a user whose Firefox has stopped working. It will start up, but nothing ever is displayed in the window. The address bar and buttons are all there, but nothing from a web site, just a white page. If I enter a url, or click on a bookmark the refresh button never changed to an 'X', but I can see traffic from her machine going across our firewall. Try to go into setup and it's the same thing. About:config displays nothing. It's all just a blank page. Other browsers seem to work fine.

I've tried refreshing, and I've uninstalled and reinstalled, but it didn't fix it. Any ideas?

Thanks.

I'm using 64-bit Linux Mint 20.3 LTS, and the latest version of Firefox from the repositories (101). Suddenly, for no reason I know, my default profile has started crashing immediately on trying to run Firefox. A small window comes up with the error message

XML Parsing Error: not well-formed Location: chrome://browser/content/browser.xhtml

     <button when-cofnection}"secure-cert-user-overridden"="" <="" pre="">

and then a line of ------^ where the ^ indicates between the t and the i of cofnection

Yes, I emphasise that I HAVE copied the error message carefully, including the mismatched bracket pair and the cofnection rather than (I assume) connection

I've managed to get a working version of Firefox by creating a new profile and using that (as in for posting this request for help), and I do have a recent backup of my bookmarks, but it will be a royal PITA if all my logins and passwords have disappeared. I don't want to go any further than this without some guidance, as all the messages I've found detailing how to fix this seem to make the assumption that I'm running Windows.

Can anybody help, please?

I’ve not had much success with my online searches to learn the details about what takes place when Firefox syncs browser information across devices. To keep things simple, assume I interested only in syncing bookmarks and staying within the Firefox environment, i.e., no syncing to another browser. Please note that I am NOT asking for help in setting up Sync on different devices or in how to turn Sync on and off. Rather I am seeking help to understand what “sync” means, that is, the details of the sort of information transfers that take place between individual devices and the Firefox Sync server.

Here’s what I currently understand. After signing in to my Firefox account on Device 1, setting up syncing on that device, specifying that I want only bookmarks to be synced, and turning syncing on, the set of bookmarks on Device 1 is sent to be stored on a Firefox server. After that, whenever one is signed in to the Firefox account on Device 1 and syncing is turned on, any changes to the bookmarks on Device 1 will "automatically" (but I don't know how quickly) end up being reflected in the set of bookmarks stored on the server. Fine so far.

In addition to Device 1 I have another device, Device 2 which has not been set up for Firefox Sync. It has its own set of bookmarks. Some of them are also on Device 1, some are not. I sign into my Firefox account on Device 2 and set up syncing on it. I follow the steps for doing this in https://support.mozilla.org/en-US/kb/how-do-i-set-sync-my-computer, “Connect additional devices to Sync.” I then click Sync Now. OK, now what happens?

1A. Do the bookmarks in Device 2 get added to the bookmarks stored in the Firefox Sync server? 1B. Do the bookmarks NOT in Device 2 get deleted from the bookmarks stored in the Firefox Sync server?

OR

2A. Do the bookmarks stored in the Firefox Sync server get added to the bookmarks in Device 2? 2B. Do the bookmarks NOT stored in the Firefox Sync server get deleted from the bookmarks in Device 2?

After whatever transfers of bookmark between Device 2 and the Firefox Sync server take place, and assuming that I’m still signed in to my Firefox account on Device 1 and that syncing on that device is still turned on, what sort of transfers of bookmarks takes place between the new set of bookmarks stored in the Firefox Sync server and the set of bookmarks already on Device 1?

3A. Do the bookmarks then present in the Firefox Sync server get added to the bookmarks in Device 1? 3B. Do the bookmarks no longer in the Firefox Sync server get deleted from the bookmarks in Device 1?

Finally, what happens to the set of bookmarks in Device 1 and Device 2 if I’m simultaneously signed in to my Firefox account, syncing is turned on in both Devices 1 and 2, and a bookmark is a) added to either device OR b) deleted from either device?

I’m sorry this message is so long, but I’ve wanted to be clear about the things I don’t understand in regard to Firefox Sync. I’d really appreciate what anyone can say to help me clarify these points. Thanks so much.

For the past few weeks I've been receiving numerous firefox crash reports & also when trying to open firefox an error indication that firefox is already open. I've never had this problem with firefox in the past, and have been an avid firefox user for many many years.

This occurred on my old desktop computer which died this week & is also occurring with my brand new, out of the box HP laptop computer (with ALL the windows updates and HP updates installed); The old computer used Windows 10 Pro, the new computer uses Windows 10 Home.

My old computer used just the windows defender for protection, but my new laptop comes with a 1 month trial of McAfee which I am using until the trial expires.

Firefox is (and was) my default web browser. The software and updates for firefox have always come from your official website and in a timely manner.

Could you please look into and resolve this issue?

Thanks so very much for being Mozilla Firefox!

I've been using Firefox almost exclusively for years now, and it's always worked flawlessly - until recently! Now, when I log into my GitHub account, I can no longer edit and commit my changes.

When I click on the "pencil" on a rendered page, I am taken to the "edit page" where I can make my changes (in markdown), preview those changes (rendered in markdown), and then commit those changes. Beginning very recently (within the past few days), the preview tab is no longer functional, and I can no longer commit my changes to the file.

I've verified that GitHub has not changed their interface by logging in from my Chrome browser, and following the exact same procedure used in Firefox everything works as it always has.

I recently upgraded from ver 99 to 100, and now to 101.0.1. I recall clicking a pop-up immediately after the 99-100 upgrade that had something to do with cookies... sorry, I know that's lame, but it's all I can recall now. In any case, I am certain this happened recently.

Please help... I have to use Chrome for a couple of things already (my brokerage account at Vanguard for example), but I despise Google, and want to limit their spying.

Thanks,
