Diễn đàn hỗ trợ Firefox

When accessing my site (in attachment to avoid indexing), Firefox blocks with a "Possible security risk" interstitial. DoH requests to the configured https://dns.google/dns-query service work from an external application on the same machine as the browser, but about:networking#dnslookuptool reports the host being unknown.

Ever since Firefox browser updated, my Home (specifically Shortcuts) has been glitching.

They do not show up, no matter how many rows I add or subtract. Web search and Recent activity still works (to an extent) but Shortcuts? Never again. Please fix it ASAP.

The webcam video image is being reversed or being flipped horizontally when using the latest version of Firefox. This is not happening in other browsers. I reset Firefox, but the issue still occurs. Can you advise/fix please?

I experienced problems with Firefox on different Windows 10 clients. The problems are only with Firefox, other browser like Chrome or Edge have no issues. The occasional issues are that Firefox loads the websites either very slow (~ 30 to 60 seconds) or sometimes not at all. At the same time, other browsers like Chrome or Edge load the same websites fast and reliably.

All affected clients have a fully patched Windows 10 with the latest build, up-to-date Firefox versions, recent processors and plenty of RAM and I periodically clean cookies/website-data/cache/history.

What could be the problem and the solution?

I just did the most recent Windows 10 updates:

KB5037768, KB5038350, KB5001716

My version is 22H2 for x64 and .Net 6.0.30

Upon finishing the update and rebooting, Firefox gave me the PR_CONNECT_RESET_ERROR on all websites. Not other browser was having an issue. I've tried all the troubleshooting steps I can find. Is there an error fix based on what I am describing that I can now try?

Thanks!
