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.

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

I use Firefox for school on my school laptop and the school desktops, which works fine. At work though, when I visit certain sites, Firefox almost acts like CSS is being disabled. I have taken a screenshot (attached) which shows how our school site looks on my work machine. The URL to the site is this: http://helenacollege.edu/

The only add-ons I'm using are: 1. Adobe Acrobat (currently disabled) 2.Open H264 Video (default Firefox plugin) 3.Widevine Content Decryption Module (default Firefox plugin)

So I don't think the add-ons are a problem. I have tried clearing all cookies, website data, and the cache, all of which hasn't solved the issue. I also get an error message saying the latest Firefox updates can't be downloaded and I need to do a fresh install. I have tried the fresh install, but the issue persists.

when ever I switch from one user to another user, when I come back to the first user Firefox won't let me change Tabs or switch to other open pages. Which can only be solved by quitting Firefox. I can reproduce this behaviour every time. In some instances it is showing the beach ball and has to be 'Force quit'. I can't reproduce this it seems random.

If anyone would like to help a novice - WIN7: I just refreshed FF after attempting to remove malware. (I did NOT perform"system restore") But now (of course), there's even more adware, including very common one that I've encountered previously ("Adpoint"?). (1) Is it possible that the refresh allowed new adware, or? (2) Can anyone point me in the right direction to again attempt to manually delete adware? (I have Malwarebytes, but clearly it has failed to prevent and/or eliminate various adware I'm plagued with) (This attempt to delete adware was a dismal failure because I've obviously allowed new adware; I've done others in the past with the same, or partially-successful results...) Thank you to any kind soul who can render constructive aid!

I've read other posts seemingly related to this and starting in safe mode and blah, blah. This has to be simple. Step one, what? the menu at the extreme right of the page that looks like an equal sign but with 3 bars? (Options, settings, sync, etc). Then what? This is a setting related to adobe and apparently its flash player, but what to do about it is extremely unclear. Background: Attempting to watch streamed content at major media outlet website, nothing abnormal, not gaming, etc. etc. Anecdotally, this worked before, but I can't prove it. This works just fine in IExplorer except for all its slowness and buffering----meaning, once asking to view live content, once finding and clicking at website on the users cable or satellite provider, the above error does not occur and the next screen one is directed to is that requesting user and password for your cable or satellite account. Once entering that data, poof, up pops the live content. So, bottom line, this isn't adobe (because it 'works' with IE), this isn't the device (because it 'works' via other method), this is a setting somewhere in Mozilla. Please advise.

Firefox developers should call out CyberArk for inept programming practices, in that their developers seem to have simply not taken the time to add proper coding to their web-based service to determine the type of web browser and do a proper redirect!

Also, since CyberArk released a recent update, the CyberArk clipboard add-on now doesn't work properly. I know that this is not something for Mozilla to correct, but Mozilla should lean on large companies that do irresponsible things which disable Firefox functionality and then just tell customers to use Chrome instead.

Sincerely, A happy, long-time Firefox user

Today, my Firefox suddenly (just after open browser) show me this page: https://qsurvey.mozilla.com/s3/Avatar-Experiment-P2?...

The URL seems to be owned by Mozilla but I am concerned about whether this page is credible because I often hear about frauds like this.

Do you know other way to confirm the credibility by except checking URL with eyes?

---

For Mozilla's staff: If this survey is yours, how about take survey with advance notice on e-mail, social media, or the pop up of Firefox Home tab? I think this is better for not to perplex the users.

note: I am Japanese, so, if I have some wording mistake on this post, please don't hesitate to tell about that.

Logging in at a hotel, I tried to use Google Chrome. Hotels redirect, and can disrupt browser history. Chrome came on the computer, and usually can keep those disruptions out of my actual work area. But this?!?!

Firefox is my default browser. Despite having Chrome open, it opened Firefox automatically. (By "it", I mean a Dell PC.) Everything hung! By the time I was logged on, my previous work session, 30 or so tabs in 2 windows, was gone. Also gone: Various add ons like Ad Blocker & NoScript. All the add-ons in fact - every last one. I keep a google search slot open on top. (Is that the tookbar?) Anyhow even that disappeared. No telling what else will turn up missing and changed when I dig around in the settings.

Damn!!!
