I'm looking for CSS Coverage in Firefox (Like it is in Google Chrome). I saw a YouTube video from a couple of years ago and there was a way to use CSS coverage at that time, but it looks like Firefox removed it... YouTube video: https://www.youtube.com/watch?v=Qrzf1lsBMMw

Mozilla says "This feature is experimental and is not yet available in Firefox", but I hope there is an option to use it in Developer Edition. (maybe we can activate it in about:config ?) https://developer.mozilla.org/en-US/docs/Tools/CSS_Coverage

In firefox fullscreen, movign the mouse to the top edge, shows the toolbars. I really like this feature, BUT when the toolbars show they push the whole page down, giving a very jarring effect as the whole page jumps down.

Is it possible that the whole doesn't jump when the toolbars show ? The toolbar could just cover the top of the page and go back into hiding as they do.

Would an extension be able to fix this ?

Firefox: all recent versions.

If I am on a website with many links and I use middle-mouse click to open each in a new tab the previous behaviour was that if I middle clicked links 1, 2, 3 then the tabs would be organised from left to right after the current tab in the order 1, 2, 3 but now the order is 3, 2, 1.

What setting do I need to change to get back the old behaviour and why is the browser changing in this way?

Platform: windows 10, using firefox dev edition.

When closing out of Firefox or closing tabs, windows volume mixer entries aren't released. It's mostly just an annoyance, but it makes it so that it is very difficult after some time to control the volume from windows as it's not possible to tell which Volume mixer entry is active.

How do I go into Gmail and edit/add/delete email addresses??? A couple months ago I read online how to do it since there is no icon or anything on the Gmail "Inbox" page any more to allow for additions/corrections. ONline I found a way to do that. I try now and the 'fix' that is offered online is to be sure you have downloaded the current Firefox version, which I just did. (65.0.2) Following online directions of clicking on Gmail in top left hand corner, nothing happens! Clicking on Gmail logo does nothing either! This should NOT be this different to make changes to people's email addresses/groups. I closed out of Firefox and reopened browser and that did nothing either.

Please help!

Thanks, dcseguin

As per the title, I can no longer access Amazon.com after the latest FIrefoc update. As soon as my update completed, I tired to access Amazon.com but to no avail. I get the following error:

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.amazon.com because this website requires a secure connection.

What can you do about it?

www.amazon.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

I can access other sites, including Amazon.ca and other shopping sites. How do I resolve this problem?

Hello,

I've been having issues with Firefox crashing over the past few weeks, increasing in how often. Today, it crashed 6 times with the above report IDs. I tried reading the crash reports but I don't quite understand what's it's telling me. Any advice on how to fix it?

Thanks,

what is C:\Users\Owner\AppData\Local\Mozilla\Firefox\Profiles\wu2w4hwp.default-1511100039413\cache2\entries\

When I use CCleaner it hangs on this address and cleans files followed by massive hex numbers. Takes ages to clean.

Can anyone tell me what this is?

Hi,

Just when life was tripping along nicely and all Yahoo's videos had been prevented from auto-play, along comes the latest version of FF -- Version 66.0 which appears to have thrown AdBlock & AdBlockPlus into turmoil and released their hold on the videos.

Any knowledge about this, or should I be looking elsewhere for the cause?

Best regards,

Ian
