OK, strange thing I cannot understand. an IDENTICLE URL ( cut and pasted from document ) Chrome gives one result and Firefox gives an abbreviated version of the same result. This is most noticable on Ebay when showing 'new today' items where Chrome shows Items that Firefox does not. And , No, its not a refresh or cache issue. Any ideas, thanks.

Firefox recently offered a choice of having open tabs appear in a sidebar on the left side. This is great but the tabs and sidebar stay visible when engaging the f11 full screen mode. This makes an awkward appearance when trying to view in full screen - such as movies or any other. The address bar at the top is hidden with f11, but the side tabs and their vertical side bar remain visible. I believe Firefox would be more desirable if the f11 key also hid the side bar. This is how Microsoft's Edge browser functions. Can't have a true full screen if the sidebar and tabs remain visible. The full screen functions works well if the sidebar function is turned off in settings but this makes it awkward for a user who wishes to use the sidebar tabs with a full screen mode. Thank you for considering this issue and thank you for your great products. Tom

My Firefox browser window has multiple tabs. I would like to be able to close them individually. The tabs do not have the 'x' symbol on them to be able to close them conventionally. I tried to right-click on the individual tabs, but the drop down menu does not have the option available to close the tab either. I tried rebooting the computer but when I open Firefox again, the same tabs are still there rather than opening up a fresh browser window with only the start tab window. I am using Windows 11 with this computer also. Help!!!

I've been able to sign in to bluemountain.com on my desktop for years, but I can't now. I can sign in on my android phone and tablet.

KINDLY KEEP BROWSER ACTIVE AFTER SWITHCHING OFF THE PC AND WHENEVER I OPEN THE PC MICROSOFT WINDOWS SHOWING SIGN OUT AND SIGNING AGAIN, BY DOING I DID IT BUT NO SOLUTION. IT HAS BEEN HAPPENING FROM FEW DAYS, I DID SYSTEM RESTORE BUT NO SOLUTION WAS FOUND.

More recently, for the past few months maybe, I sometimes get a white menubar when Firefox is in the forefront. Clicking on it will restore the menubar.

Here's a pic

I am using the latest Mac OS, 15.4.1, and it happened with the previous version too.

Thanks for any help.

The iDrive backup app on my synology nas is accessed via a web browser over my local network using an ip address. It has a two step security setup. First to enter Synology credentials and then iDrive's. After entering the iDrive credentials, all I get is a spinning wheel. It is supposed to present a box to enter a validation code, sent to me by email (which I get). The box is never shown.

The process works in Chrome and Edge successfully. I contacted iDrive support and they told me that since it fails only in Firefox, that I should contact the browser vendor.

There is no error message.

I tried clearing my browser cache, restarting Firefox and my computer, none of which helped.

Please can you advise me?
