Firefox Support Forum

I'm so unhappy now I don't know where to begin.

I was having trouble loading a website (lowes.com), continually getting an "access denied" error message. It occurred to me that I'd read somewhere that if you told Firefox to "forget this site," it might solve the "access denied" problem. I didn't remember how to do this, though, so I searched online and found a site that said that adding the "Remove" button to the Toolbar and clicking it would solve the problem. I dutifully added the "Remove" button, then, before clicking it, I triple-checked that the "Forget the last Five minutes" was selected and not any longer period of time. After all, I didn't want to lose everything!

Well, I did.

I had literally hundreds of tabs that I was working on open — they're all gone. All of my history — years worth — is missing. More things may have been deleted, but, to be honest, I'm afraid to check.

What did I do wrong? Or is the "Remove" button buggy?

And while I believe that everything that's missing now is irretrievably lost, if anyone has a hack to recover anything, I would be so, so grateful if you'd let me know.

Thanks in advance.

P.S. I wrote this post up once, hit "Submit," then, after an interminable period of time, the screen went to a blank page. My original post has never appeared. Is there perhaps something wrong with my Firefox (which has been perfectly fine up until now)?

I used to run Firefox 88.0.1 (64 bit) on a Windows 7 PC. With lots of help from this forum I wrote a userchrome.css file to make several changes to the appearance.

On a new Windows 10 machine I installed the same version of Firefox (since I don't care for the latest one). I added my old profle to the new installation and selected it as the default.

Unfortunately, when I opened the program I was prompted to create a new profile; there didn't seem to be any way around this. So I let it happen and tried simply copying my old chrome folder into it - I thought at least I could make the visual changes even if I couldn't import my bookmarks and so on.

But this didn't work either: when I run the program, none of the expected changes are there.

Presumably I've done something wrong, but what, exactly? I'd be grateful for any thoughts. Ideally, I'd like to use the whole of the old Win7 profile but if that's not possible at least changing the appearance would be pleasant.

Many thanks.

When I open Firefox with a dozen tabs showing, Task Manager typically shows Firefox to be using 1.3% CPU, 715 MB Memory and 0.1 MB/s Disk. However, as soon as I open www.walmart.com in a new tab, Firefox CPU goes up to between 34% to 52%, Memory to 13,900 MB and Disk to 50 to 200 MB/s. If I reboot, it is repeatable. I have an AMD Ryzen 5 3600 with 16 GB. What's going on?

Please tell me what to do to have the magazine work. It used to, but I think that some new thing like Adblock must have changed it and I cannot read the magazine now. Thanks.
