Firefox Support Forum

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.

I broke an old computer and have my logins from it on a backup drive in logins.json and key4.db. I can't work out how to transfer these logins to my new computer. I've tried creating a new firefox profile since I am nervous of losing logins that are on my new computer, but then I am totally lost.

Audio was working fine until recently. Now, firefox has no audio playing on any site.

Some sites show "PLAYING" in tab, but others like YouTube don't show that notification. Even with "PLAYING", there is no audio output.

I checked Windows settings and Firefox is set up correct (and the same as it was before it stopped working), see screenshot attached. Otherwise, I restarted Firefox, tried it in troubleshoot mode, and reinstalled Firefox. No changes.

Possible system changes include: Maybe a Firefox update occured and broke the program? I installed the game Civ5 from Steam which required some Windows VS redistributibles installed.

Hi! There are multiple recent threads on this issue, and not one of them has a solution, so I'm asking again. I want to increase the font size of the top header text, specifically the bookmarks toolbar, search bar, and tab titles. The text is too small for me to read. It would also be useful if I could increase the font size for the applications menu (the hamburger drop down menu in the far right of the header).

I do not want to increase the size of anything else, so changing layout.css.devPixelsPerPx is not the solution. I have changed my global zoom settings, and set them specifically to "Zoom text only", but this setting does not effect the bookmarks toolbar or the search bar. Changing the default font size also does not increase the size of this text.

Just to clarify again, these threads are not solutions to my question: https://support.mozilla.org/en-US/questions/1214027 https://support.mozilla.org/en-US/questions/1293358

I have an extension (completely blank) that can't be deinstalled. I am trying to use the "refresh firefox feature" to get rid of it, but the button simply isn't where it should be. The text is german, but none if these Buttons are the one I seek.

Hi all. Did a search but found nothing that helped. Just updated my Fedora 36 workstation and tried to play videos in CNN and MSNBC web sites and get the error message: "Code: 4 | Message: Something went wrong during native playback." I am using the latest Firefox WEB browser. UTube videos are playing fine. Someone has stated on the Fedora forum that they have the same problem but has no problem in Chrome on the same machine. Any ideas? Thanks in advance. Bob BTW, this happened in two machines running Fedora 36 and Firefox 101.0.

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.

Why are google sites (Youtube, Gmail and Search) getting disconnected when all other sites are still connected to the Net? This has been happening since November 2021.

When that happens I close the FF and then immediately open it. Now the google sites work properly.

Never had that problem with other sites.....never!

Why the hell is this happening? Is FF responsible or Google?

So what is the solution?

Lighter fonts (from multiple families, and on multiple websites) are rendered so poorly they are barely legible.

I already tried disabled performance settings, and turning off ClearType in Windows (it barely had any effect)

How do we fix this?

My workflow in Firefox involves 100's of open tabs pertaining to work, personal etc. I regularly bookmark all the abs using the 'bookmark all tabs' feature in the Bookmarks drowdown (or the equivalent 'select all tabs' -> 'bookmark all tabs' by rightclicking on a tab) which offers the option of saving the tabs in a new folder name I specify. As of the last couple of weeks, the option to enter a folder name no longer exists. I've attached a screenshot of the current pop-up when I choose 'bookmark all tabs'.

Perhaps related: this may have started occuring after I upgraded to the latest version (v. 101.0 on MacOs 12.4 on Macbook Pro) or the timing may be a coincidence.

Saving the 100s of bookmarks every week is an essential part of workflow; I've been doiong it for years, and I really need to have this ability back. Please help me debug this.

Thanks!

This question has to do with logging into web sites with an email and a password. Firefox 101.0.1 (64-bit). Windows 10.

On many sites, when I click in the email field, a drop down list of email addresses appears from which I can make a selection using the mouse or up/down arrow keys. Some web sites have as few as two email addresses in the drop down list, others have many more. I recall that one site has about fifteen email addresses in the drop down list.

How can I remove a non-applicable email address from the drop down list?

How can I clear the drop down list of all email addresses?

Thanks.

Firefox allow to disable access to canvas for lowering fingerprinting, it's cool !

But as web developer : i like to ask this access before try to using it,

Something like :

1. Do you alllow canvas ? 2. Show the browser part 3. Wait for user answer 4. It's OK : download PDF done with canvass 5. It's not OK : shown an error to user.

To avoid such situation (see screencast)

i am filling out a pdf form from the canadian government, and it say javascript has been disabled. i need to know how to enable it to complete the form. i am using windows 10.

For some reason, whenever I load a pdf from within Firefox, I get a new tab with the regular toolbar displayed on top of pdf files, but the document itself is completely blank (see attached screenshot). This issue just started today and I assume it was a result of an update, since I don't recall making any changes to my settings (I'm using Firefox 101.0.1 on Ubuntu 20.04).

I've tried opening multiple files from a variety of sites with the same result. All of them open fine using my system's pdf viewer, as well as from within Chromium. I've tried disabling my plugins, putting Firefox into safe mode and resetting all the handlers, to no avail. Any help would be much appreciated.

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?

Firefox version: 101.0 (64 bit) OS: Fedora 36
