Firefox Support Forum

Videos from YouTube I've embedded in a couple of web sites will not go fullscreen. I can go full screen on the same videos when on the YouTube site with no problem. On my embedded video the fullscreen control is there in the bottom right corner but I get the message "Full screen unavailable. Learn more." The source of the video is not blocking fullscreen ("allowfullscreen></iframe>" is included in the code), I've checked all my permissions, specifically for the web sites in question even, as well as my Add-Ons (I changed them all to 'Always Ask' in case some new one or update was bugging things up). What am I missing?

Hi all Since I installed FF 70.0 there are no more titles in the title bar. I looked in the Preferences and found nothing. I am running OS X 10.9.5 Mavericks. TIA for your help. Nick

almost every time I use Firefox, as soon as I quit Firefox, the crash reporter message comes up. how can I make this stop happening? Firefox isn't crashing but the crash reporter is working overtime as if it is!

thanks for your help,

Debbie

This has been going on for longer than I should have let it. For the record, I have tried going into Safe Mode but it didn't fix the issue. The crashes that I receive are random. I can be watching a video or I can just be reading something on a forum, regardless the browser crashes. I had a Java Applet plugin that was out of date so I also tried disabling that but I still had the crashes. Any help would be greatly appreciated, here are a couple of my crash reports.

I installed Firefox 59.0.2 tonight, and was alerted that a Trojan Horse was installed with the crash installer app. ClamXav's Clam Sentry alerted me—and yes, the definitions are updated daily.

Link to installer: https://download-installer.cdn.mozilla.net/pub/firefox/releases/59.0.2/mac/en-GB/Firefox%2059.0.2.dmg

Is this a new false-positive? Clam Sentry alerted it as a LIVE virus, so it wouldn't allow me to quarantine it—delete only.

I deleted everything, but pulled this from Console:

It seems like the feature is super bugged and fundamentally flawed. Not only is it halfbaked, but I have very little to no control over how it works. I end up with 40 hidden pages because of my style of browsing. Even using the Simple tab groups gets unnecessarily convoluted. Ive got like 60 hidden tabs in this browser window alone, but they arent displayed logically and you cant tell if they are assigned to another window in STG or what. So, whats the point of it? Why must I, as someone with amply memory and storage, must deal with its illogical behavior?

I am on firefox 25 and oxs 10.9, and all of a sudden for no reason, the 2 finger scrolling stopped working. its not the mac because scrolling works on everything else except for firefox. I don't really know what happened. I've already tried reseting firefox and the scrolling will work for a bit and then suddenly not work anymore. if i restart it, the scroll will work for a bout 5 minutes before disappearing.

Why do I have to select "continue allowing" every time I visit certain sites in order to be able to type into flash based form fields? See attached image for reference to what button I am referring to. Until i hit the "continue allowing" button I can not type into the form fields. I have tried removing and reinstalling flash. refreshing firefox, and clearing cache and cookies, and deleting the permissions.sqlite file. Nothing has worked. This issue just started happening a few days ago. Please let me know what I might be able to do to fix this.

This has to be the most bizarre thing I have ever seen.

There are 2 users on my iMac - myself and my wife.

If I use my account to access a certain internet page on Firefox, then select some text and go to File>Print, I have the option to "Print Selection Only". If I don't select any text, that option is greyed-out. This is how I expect it to work.

However, if my wife uses her account to access the very same internet page on Firefox, then selects the very same text I selected and goes to File>Print, the option to "Print Selection Only" is greyed-out.

I have no trouble selecting text and printing the selection from my account, but my wife cannot do the same from her account on the same computer with the same web pages and the same printer and the same selected text.

What on earth is going on here?

I don't know if its the latest update (65.0.1) that did this to me since I don't know when I last went to the page, but when I go to Add-Ons Manager now, all I see is a blank page (or rather rows of white tiles) rather than a list of my add-ons that I can click on to modify/remove etc.

Any suggestions?

Thanks

Sioe is supposed to display a P_DF or some other text or image format., , Got that message. , ,It links to the Add-on manager, but gives no clue about what plug-in needs to be managed.

And of course I have Acrobat reader, and it's not disabled.

I'm using a Mac, OS 10.7.5. Firefox has worked perfectly on it for years. Today it is just showing a blank screen with just the traffic light buttons in the top left corner. None of the dropdown menus work. he Safe Mode dialogue is also completely blank when I try that. I have tried reuploading Firefox and have deleted the prefs file. Nothing seems to work....

I hear fireworks and "When Johnny Comes Marching Home" on flutes every time I open a new tab. It is jarring, intrusive and totally unwelcome. Why is there and how do I stop it? I am using a MacBook Pro.

Following an update, the order of the Firefox "Window" menu has changed (probably to last z-index before close, rather than the static order I need to keep track of all the windows I need to keep open). Is there a way to determine this order or undo this change?

Over the last two days, my tabs only load when I click on them. Exploring the preferences settings I see that the option "Don't load tabs until selected" has vanished, even though it's still mentioned here on the support pages... Help!

Simple. I had Firefox ESR 52.9, along with some add-ons that will not work in 55+.

I thought I had disabled automatic updates. But to my surprise, I got updated to 60.

I don't like what I am seeing. My system has a standard of dark text (preferably black) on light background (normally white, light gray if not active), and you are basically forcing a dark theme even in the daytime, even if gray on black is hard to read, even if my monitor cannot go up to "bright" in a short space/pixel count.

I don't like the ultra-tiny little icons for the new tab page (I do like being able to see more sites; the old one capped at about 54 sites no matter what settings I chose). I don't like the new "hidden menu" that is appropriate for touch screens that doesn't respond to keyboard (control F2 on Mac, alt-space on Windows).

I don't like the look at some of my add-ons have changed to. I don't run a touchscreen tablets, and I don't want my computer to be forced to use a browser that pretends that it is.

I don't like that the new Firefox basically forces pocket on me. I don't like pocket, I don't trust its terms of service/privacy policy, I don't like that Firefox/Mozilla has chosen to basically make it a first-class citizen even though it doesn't put my interests first and foremost. I don't like that Firefox has basically decided to say "whatever Google does, we will follow". I don't like that Firefox/Mozilla has abandoned its view of "what is best for the browser user", and gone to "whatever is best for the website".

Ideally, I would like to have ESR 52.9, as well as ESR 60.X, side-by-side. I would use 52 for 99% of what I do, and only switch to 60 for those sites that simply will not work at all in 52.

Ideally, the only difference would be the display of the websites. They would share the same history, they would share the same set of bookmarks, etc. There would be no loss of data when I move between one and the other.

I have a Time Machine backup. What do I need to do to get the old Firefox back, and prevent it from instantly auto updating back to the new junk? Including my old add-ons.

I have version 42.0 Firefox on iMac running Maverick OS. It does great on most web sites. But Metromile's web page for Account monthly statement shows weird font or characters and is totally unreadable in fFrefox. I can see it fine with Safari or Chrome. Other pages on Metromile site are fine with Firefox. Your program would not allow me to attach tiff or pdf screenshot file, but I can provide it separately.
