I need to install PKCS#11 modul on iMac (OS: Ventura 13.7.4) for signature authorization. I try: Settings-> Privacy and Security-> Certificates-> Security devices-> Load-> Modul filename: /Applications/CertiliaMiddleware.app/Contents/pkcs11/libCertiliaPkcs11.dylib , but I get an answer: "Unable to add modul". In order to install a certificate for signing with a card, I was informed that I need to install this modul first, but it doesn't work. What should I do? Thanks, Martina

Version 148 is very slow. When there are 5-10 downloads, other websites won't open. That's why I use version 140. And why are there so many files in the folder - ....profile\storage\permanent\chrome

My son tried to voicemail me on Messenger but it said this browser does not support voicecalling. I have used this in the past, still on Firefox. I used to get note that a call was coming ans option to connect or discard. Now there is no option to connect. What can I do to get this service back?

This has started a few days ago. I'm running Firefox Desktop on Windows 11. Browsing is perfectly normal, until I try to watch a video in full screen mode. It plays normally for a few seconds and then my whole system freezes, with no response to any action except for hard reset. This has never happened to me before, and all other browsers I try do not demonstrate the same problem. Is there any solution other than changing browser permanently?

Firefox has "Open previous windows and tabs" ticked in Settings. I had to force restart MacOS, and upon starting Firefox again my existing windows are invisible. They are shown in the Window menu and when right-clicking the Firefox icon in the MacOS dock, however when I select one of the windows it does not become visible. Command+` does not show the windows either.

I can however open new windows.

I tried renaming xulstore.json per this old article with no effect.

How can I make the existing windows visible again?

I get the message: We're Sorry Firfox had a problem and crashed. We'll try to restore your tabs and windows. To help us diagnose and fix this problem, you can send us a crash report. I sent the crash report multiple times.

I added a screenshot of my MacBook Air info.

When I play YouTube videos in Firefox, they are constantly choppy and slow, even though my internet connection is fine and other browsers (like Chrome) work smoothly. This happens with both HD and lower quality videos. I've already tried clearing cache and disabling extensions, but the issue persists. Please help me fix this.

I am encountering more and more websites with problems they attribute to Firefox. Many of them recommend using Chrome or Edge and some insist upon it or they will no longer support problems. Direct TV will no longer work with Firefox at all and they will not fix it. Several of my other regular websites will work partially, but have pages that simply will not work with Firefox. I have resisted using Chrome or Edge for years but it is getting harder and harder to do as on line systems continue to have problems with Firefox and their only suggestion is to use Chrome (which works when Firefox doesn't). Any ideas/suggestions?

When I play a video in fullscreen and type something, when I typed something in the IME and will press Esc to quit the IME, the whole fullscreen will be quitted. The expected behavior is to quit the IME only, and the fullscreen should be quitted only when there is no IMEs.

The issue has been existing for years.

The last 2 days when I have shut down my computer then restarted, my Firefox profile has disappeared, along with all my bookmarks, passwords etc. I spent several hours yesterday following all the advice here to get everything back, but nothing worked. I had to create a new profile and then import an old passwords file, which I luckily had saved in Excel. This morning when I switched the computer on, the same thing has happened. I cannot even open Firefox without creating a new profile. I get a pop up box (screenshot attached), which shows no profiles, and i have to create a new one to even open Firefox. Every time I close out of Firefox and want to go back in, I am asked to choose a profile. This has never happened before.Before i give up forever on Firefox and go over to another browser, do you have any ideas how i can stop this from happening, and get my original profile, passwords, bookmarks etc back? Thanks.

I reached out and was advised could be something wrong with the software however I believe I have the latest software as i just downloaded the browser today. I am also able to access the same site on my phone and my IPAD not sure why it wont work here.
