I understand the newest version of Firefox offers support for WebP images, which is cool and great... but not when I need to download those images for use on my computer. As an artist I need to be able to save things as .jpg or .png for my art programs (or even preview) to be able to open them. Is there any way to make this an option, or to not default to webp when saving images?

I've also tried changing the extension on the file using the "all files" option but it just corrupts the file and won't open them.

This has just started happening: every time I try to print from a remote website (thetimes.co.uk) I get this message:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

It is not the website, as the request works from Microsoft Edge.

I can't see any changes to the parameters which might have affected this.

Any ideas please?

When I open Firefox I get a message “Do you want to allow this app to make changes to your device?” If I click on Yes everything then proceeds as normal. If I close Firefox and then re-open it, the same thing happens (even as soon as one minute - or less - later). This is recent behaviour (last couple of days) and there has been no known event which might have triggered this. Other browsers (Chrome, Edge) do not exhibit this behaviour. How can I fix this (or do I just switch browsers)? The settings re Compatibility Mode and Run as Administrator are both unchecked.

Thanks for any assistance.

Hi. After updating to 58.0 my system crashed and Firefox was rebooted. However the 15 or so tabs I had open were not restored, and I can't find any file in the Firefox/Mozilla folders on my computer that might contain a record of them (all files are from either after the crash, or the newest ones before that are from early January). Is there a way to restore the session from synced information?
