With Firefox version 63, I have the problem on YouTube and Netflix, if I snap Firefox in a corner (with mouse or WIN + arrow keys) and switch a video to full screen, left and right is still a few pixels square. In addition, the taskbar is in the foreground (can not be fixed). [IMAGE 1]

If not left, right (top or bottom) snapped then it works, if Firefox is maximized too. The error occurs only in Firefox. Exit Explorer.exe and reboot PC does not work. Error exists since update on the first day of release (early October) - version has been withdrawn by MS,

I also installed the version on my laptop and have been updating ever since.

Apparently the error also occurs with some others: https://www.reddit.com/r/Windows10/comments/9lwzmm/fullscreen_broken_in_october_update/ but it has probably not changed.

Useful data: Windows version 1809 build 17763.134 Graphics driver up to date Firefox completely reinstalled (profile, cache & cookies deleted) even without add-ons started. 2 monitors On the laptop (also tested with 2 monitors) no problems.

I am thankful for every help. Error is really annoying.

I've had no problem with previous versions of Firefox. Since installing version 63.0.3, constant problems with crashing, hanging or loading homepage and websites extremely slowly. Sometimes loading of homepage cycles through two or three partial sequences before completing. Have tried all obvious recommended solutions without success, including safe mode, refresh and reinstall. Am using MacBook Pro 10.10.5 and BT as my home page. I use Safari as my other browser and it continues to run without any issues

A while back I started having problems with tabs hanging in Firefox. This happens arbitrarily, in any site, without any user input. It may happen with tabs that have been on the background for a long while or with a brand new tab that I just opened. I'm attaching screenshots for a tab (that was) showing Facebook and one for a new tab without any site loaded. Whenever this happens, there will be a "WebContent" process at 100% CPU. The only solution is for me to kill that process.

I'm seeing this in two different computers, work and home. The usage pattern between these two is quite different, although I do have Firefox sync in both of them. I've tried deleting my profile (rm -rf ~/.mozilla/) but that hasn't helped. I've tried using safe mode and couldn't reproduce the error, but since these crashes happen about twice a day it's hard to say for sure. There are no crash reports in about:crashes.

Any tips to troubleshoot this problem?

$ firefox --version Mozilla Firefox 63.0.3

I was recently experiencing slow load and the spinning wheel and recently disabled hardware acceleration. However, since then, my browser hangs and requires a force quit of Firefox. I'll re-launch FF and restore my session and everything is fine. I'm not exactly sure what settings I can send to you. I have some crash reports, but they are probably because I force close the application.

I've had trouble accessing websites that use a certificate that's signed with the DigiCert Root CA. As an example, if I open up blog.mozilla.org, I get a SEC_ERROR_UNKNOWN_ISSUER.

This is somehow related to my user profile. If I create a new profile, the problem disappears.

I've tried deleting cert*.db in my profile directory to no avail. I checked about:config and I couldn't find any relevant non-default configuration.

To my surprise, if I want to manually set the trust of the certificate in the certificate manager ("Edit Trust"), it tells me that the certificate is trusted. However, if I click on "View Certificate", I get the following error: "Could not verify this certificate because the issuer is unknown."

I don't know much about CAs, but it seems to be surprising how the issuer of a Root CA could be unknown, isn't that the whole point of a Root CA that it does not need to be signed by another certificate?

The more important question: Where in my profile may I have a non-default option that causes Firefox to not trust the DigiCert Global Root CA?

For years I have used Firefox and been able to login to my NatWest Account - suddenly I am no longer able to have this facility. SECURE CONNECTION FAILED - The connection to the server was reset while the page was loading. The page you are trying to view cannot be shown because the authenticity of the received data couldn't be verified. Please contact the owners of the website to inform them of this problem.

I looked on your help site to see if there were others with this challenge and found some comments from some sanctimonious prat to the effect that this should be remedied by the website owner and that eventually the website would no longer be able to be accessed by any other browser such as Chrome, Edge etc. Great, but I need to see my bank accounts online and rather than change banks, I am changing to Edge so that I can. Eventually NatWest may have to change their security but until then I am going to move away from Firefox, and, I know I only contribute a small amount to your "cause" every year but I shall take that away as well - you are too "holier than thou" in your approach to security and take no thought of how its implications affect the user.

Hi there.

After years of not using Firefox, I decided to give it another try and installed it on my 13 inch Mid 2010 MacBook Pro. It's the latest Firefox release (63.0.3) and I notived that it is still a lot slower compared to other browsers. Pages loading slower, videos are choppy, and it also seems to use more power and memory.

So I decided to do some tests not to rely only on my observations, and it seems that I'm right. I'm using the latest Mac Os High Sierra 10.13.6 with SSd drive and 8GB of RAM.

I googled some browser tests, and I found this website: https://browserbench.org and ran all 4 tests available, and compared it to the latest version of Safari (12.0.1), the latest version of Chrome (70.0.3538.102) and here is what I found:

Firefox: Motion Mark: 49.13 Speedmeter: 21.5 Ares-6: 207.57ms JetStream: 62.505

Chrome: Motion Mark: 54.58 Speedmeter: 27.4 Ares-6: 72.39ms JetStream: 62.919

Safari: Motion Mark: 98.79 Speedmeter: 34.5 Ares-6: 58.29ms JetStream: 85.729

As you can see, the Firefox performance is rather poor, and it's been like that on my MacBook since I remember. I thought this new Quantum one will be much better, but I'm very disappointed.

Why is this happening? Why is Firefox so slow? I'd appreciate your thoughts on this.

Best

When trying to go to websites using Firefox,i kept getting a message saying there was a problem with a certificate. So i went to Advanced and clicked on Add Exception. This worked for some websites but not others because some did not have the option to "Add Exception" . I even got the certificate problem with the Firefox and the Wikipedia sites, i think. This problem may have come about because i first started to have a problem a few days ago with a redirect popup when clicking on websites which said to purchase a File Converter. To try to stop this redirect popup, i tried Zemana, then Malwarebytes. After trying Malwarebytes, i think this is when the problem of certificates began. Also, many times a Malwarebytes message came up saying that an outbound trojan had been blocked. Microsoft Edge and Google Chrome did not have the certificate problem, but did have the message about the outbound trojan. I read several articles on the Firefox Support for the certificate problem and the Malwarebytes site about the outbound trojan. But so far the only thing that got rid of the certificate and outbound trojan problems was when i tried Hitman Pro yesterday.

Not just login fields, but in about any text field in Firefox I'll get suggestions based off previous entries into similar fields. See attached image. The problem is that sometime I need to remove entries from this list. Sometimes a password is accidentally typed into the login field, and then it get saved in that list (not good!).

I'd love to just delete entries from a given list, but even if this can't be done I should be able to just nuke all saved entries in all fields. It seems like I've done this before, but when I look at the Firefox controls I cannot find how to do this.

I can look in Tools -> Options and under Privacy & Security there are promising things, but nothing there helps either. I've deleted everything from Saved Logins, but these suggestion lists persist. Autofill Addresses also looked promising, but the few choices there were just real addresses, not logins.

I'd hate to lose all the saved data, but I cannot have passwords visible like this. Thank you!

New setup (new PC), logged in to firefox account, both sides ticked to sync options, add ons and bookmarks. The latter 2 synced, but not the options (ie. layout) and the add-on options totally do not sync. Default firefox setup is super annoying with it's pocket, no direct icon for bookmarks etc etc. Not mentioning custom filters for ublock. So I expected this all will sync but it doesn't. One more thing - any way to sync passwords? Some offline method?

Cheers

Hi, the problem is, there is no way to install a multi-language pack. The extension is downloaded well, but when I write in the language all is mark as wrong written. Since I am tri-language English, Spanish and German, this is a main issue for me. Everything what is not written in English is marked as wrong written. In this moment I am forced to use another browser, it is a pity because I really like Firefox, but the language issue break down the workflow in such way that I can't use it. I hope you can give me a hand.

Have a great day. Karsten
