Hi, recently I setup a home server for my local lan. Through the use of AdGuardHome and Nginx Proxy Manager, I have attempted to redirect websites I wish to avoid (in this case adult websites). The problem is that Firefix gives the error code MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT and won't allow me to create an exception. As an example, i've tried redirecting google.com to duckduckgo.com. I've looked up solutions to this but nothing has helped. Thanks

Firefox Color "New Tab Background Color" reverts to black when theme is changed.

If I'm using "Blue Theme by Valou" and then change the "New Tab Background Color" to a light blue (#b7dff0), the theme changes (when I don't want it to) and the "New Tab Background Color" does indeed change to light blue. Unfortunately, when I re-select "Blue Theme by Valou" by disabling the unwanted theme and enabling "Blue Theme by Valou", the new tab background color reverts to a default slate (nearly black) color -- the light blue background is no longer honored when I open a new tab.

Please let me know if you need more information.

When opening the browser for the first time, my opened (saved) tabs begin to load and then pause as though my entire internet connection is lost. Some will time out, others will just sit there. If I try to go to a new website, I get a connection error that says I have no connection to the internet. This only happens in FF; my other programs are not effected by the drop in connection and the Windows connection manager shows that I'm live the whole time. The connection resumes and all goes back to normal between 20-60 seconds after the initial drop.

This only happens when opening the application for the first time after a reboot but doesn't matter if I just started Windows or wait 5 minutes to open FF. What is going on here? I've been using FF on this computer for 2 years with no issue like this. The issue has remained after a full format/wipe of the Windows 10 and clean slate install of FF.

I am very concerned about a proxy or some kind of man in the middle switch being flipped. It's the same pause in network access that I get when enabling a VPN service. As a note, I do not have a VPN installed at this time.

Any help or advice is welcomed, thank you.

Receiving the following message when trying to log onto well know and compliant crypto website:

403 ERROR The request could not be satisfied. Request blocked. We can't connect to the server for this app or website at this time. There might be too much traffic or a configuration error. Try again later, or contact the app or website owner. If you provide content to customers through CloudFront, you can find steps to troubleshoot and help prevent this error by reviewing the CloudFront documentation.

Never had this problem in recent past, only after updating Firefox to 93 (64-bit) Linux Ubuntu 20.4. I DON'T USE CLOUDFRONT. So what else may be the issue? Thank you.

Hi, I am using the dark mode in firefox which is god sent boon to persons having glaucoma, with dark mode in firefox and dark reader add on. This was going well and after a recent update, I could not find it working. The dark mode is enabled and dark reader was there, but the browsing pages only shows in white. Has firefox changed anything recently to have this issue? If I miss something would the experts say, how to get back my dark browsing experience in all sites. If I find anything not visible in some sites, I used to go the windows properties and change the contrast theme to windows basic blue theme and then switched back to dark theme. this was helping the glaucoma persons very much. please, say how to solve this problem

I have today commissioned a new HP laptop running Windows 10.

I have downloaded Firefox and done a straightforward installation. I have viewed a couple of web pages but notice that when right clicking there is no longer a screenshot facility in the little menu box that appears. Trying Control + Shift + S does not work either.

I am writing this using Firefox 93.0 for Linux Mint on an old Toshiba Satellite and I have the facility - both right click and keyboard.

Has the facility been discontinued in the later version?

Many thanks in advance

Can someone help me fix recent frequent crashes ? This is just yesterday. I tried troubleshooting mode and it didn't happen there, although I didnt give it a long trial. I deleted all extensions, and I reset Firefox. Any ideas?

Hi I know you can just click on a tab and drag it to the left or right to sort out order etc. But I recall in the past, or maybe it was a different browser I'm not sure, but the little down arrow at the top left of the firefox browser that drops down a list of your opened tabs, I recall being able to click on one and move it up and down which is much quicker and easier. Maybe its the bookmarks I'm thinking of that lets you do this. But yes, is there a way to move tabs up and down in that window, or any extentions out there that enable such a feature. Thanks for the help.

There has been a legitimate issue with the bookmarks since the 92.0 update. This applies only to Windows 7 users. The list is very lazy and will actually freeze up. It takes forever to highlight the bookmark you want and the favicons are delayed in populating. Refreshing Firefox doesn't work. Renaming favicons.sqlite and places.sqlite, and those with the -shm and -wal extensions, if existing, doesn't work either. I don't need help from contributors. The following message is to the developers &/or whoever bastardized Firefox since the 92.0 update...


As I stated, this is a Windows 7 issue. The developers should fix this problem for us Windows 7 users. It was them who caused this issue since the 92.0 update. Everything worked perfect until then. Here’s a bright idea for the developers. How about getting this matter fixed, so that us Windows 7 users can have the same functionality as everyone else. Stop screwing around with a million and one updates every year. You people are doing more harm than good. The people running Chrome are a hell of a lot more intelligent. No issues whatsoever with Windows 7! Try that on for size.
