Diễn đàn hỗ trợ Firefox

I'm using FF on a Mac Mini, Sonoma, and for the last few days FF doesn't open in the same position it was in when I closed it. When I open FF it's about half of the size it was when I closed it. I then drag a corner to the size FF I want, but this is a very new issue.

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?

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?

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.

Samsung Galaxy S24 Ultra running latest Android update and latest Firefox update. I set Firefox as my default browser. I have un-installed all updates for Samsung Internet and removed all permissions for it. Disabling it is greyed out. Some apps that I use have links to websites. Too frequently, when I go to one of those links, the intro screen for Samsung Internet opens. Then, when I look at the settings in Firefox it is no longer set as the default. Then I set Firefox to default and go to my phone settings to see that Firefox is selected as the default. If I open the previously mentioned app and choose the web link, Firefox will open. But somewhere along the way, the default changes back to Samsung Internet and it's a vicious circle. I have posted in a Samsung forum but haven't gotten a reply that solved the problem. Please help. Thanks Mike

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.
