Firefox-Hilfeforum

Can anyone supply updated code for the userChrome.css for restoring Tabs to below Menu bar, Location bar, and Personal Toolbar? The code below was working until I upgraded to 65.0.

/* tabs on bottom */

1. navigator-toolbox toolbar:not(#nav-bar):not(#toolbar-menubar) {-moz-box-ordinal-group:10}
2. TabsToolbar {-moz-box-ordinal-group:1000!important}

Thank you for the help.

edited the title of this thread to include Windows 10 as the operating system the OP posted from

recently i'm having a new problem this time on youtube , despite not having the famous codecs before could still watch old videos , but in those days i'm getting error of browser doesn not recognize video formats also on those old videos ( that basically could watch before ), having this problem from 2/3 days , randomly i can still see a video , but it's starting to happen much , nothing is changed on my pc , no virus , no everything , any way to fix it ? as always i have vista 32 bit and firefox 43 , thank you everyone for any help

Like in the description I can not save the changes I made in the about:config page no matter what I do, I already do an re installation also use the refresh button and delete the preferences file and still the issue remains.

I just updated to Firefox 65 and suddenly my tabs are once again up in the gods. How do I get them down below the bookmarks toolbar and address bar? I've tried Userchrome and followed the 2017 video (which was very lcear by the way) that was recommended in Firefox support but it didn't work and I'm at my wits end. I hate this tabs on top thing and just want to put it back where it belongs. Please help?

Hey all.

As some of you may know from some older questions, I have two machines. One a Windows XP desktop running Firefox 28, as it was the last version I knew that supported Windows XP, and the other a Windows 10 Laptop that is on the current version of Firefox.

Sadly, my post is about the XP version of Firefox tonight. Please don't judge. The computer still runs, so I haven't seen a reason to get rid of it, and I split my time between the two machines.

I'll get right to the point. Up till tonight, Version 28 on Windows XP had worked perfectly with Youtube— Or at least as near to it as the old machine could get— as it typically played every video more or less with no issues via the HTML5 video player that Youtube supposedly uses. However tonight, I have been getting very hit or miss responses on youtube, as the HTML5 player does not always come up, and when it does not, I get an image of static with text saying that my browser is not recognizing any of the available formats. When I check youtube.com/html5, it is showing that it recognizes some of the formats— apparently only two so far, and HTML5 itself isn't even listed among them, though there is a checked box saying that the HTML5 player is used when possible— so I'm just wondering, what the hell happened here? As I said, Up till basically last night, everything worked more or less fine on Youtube, with there being only a handful of times the issue of a video format not being recognized came up. In fact Firefox 28 is still somehow pulling up the classic version of youtube, rather than the new version, which I have no explanation for.

Did Youtube stop supporting HTML5 in favor of a new video format, or is something else going on here?

If there is a later version of Firefox that still worked for Windows XP ( I think I remember someone suggesting that 43 would work, but half of the extensions no longer seem to exist for it that I use, including classic theme restorer— though I think someone at waterfox said they may have archived that extension, however I have no idea how to access or use archived extensions— but any port in a storm at this stage) that supports whatever Youtube is using, that would be welcome information, despite my attachment to version 28. Hell, if I could make sense out of how to set up multiple profiles for Firefox, I'd run the classic 28 and whatever later version might run with whatever Youtube is doing so I wouldn't have to give up my preferred version on this old machine. Again though, sometimes the HTML5 player works, and sometimes it doesn't. So I dunno what the issue is here and if there's a fix I can find for Firefox 28, as it is the last version I knew worked for the older machine.

Thankfully, this issue doesn't come up on the Windows 10 laptop, so this is not repeating itself there, Thankfully. But is there a way to fix this, or am I just stuck with considering Youtube a partial, if not complete loss on the XP machine? It's one of only three sites I even still use the browser for. The other two being fanfiction.net and wikipedia.org

And if there IS a later version of Firefox that still actually works with XP, does anyone have a basic 'here's how even an idiot can fix it so you can run two versions on the same machine' explanation of how to set that up? I am NOT a technical person, and going into excessive detail does me no favors. I just need simple, point by point instructions that are, in effect such that a three year old could read and understand them if there is a way to have two versions of the program running.

Though this does also make me wonder if I can install the browser in my second internal hard drive rather than the primary C drive and still have it work properly.

Anyway, sorry for the rambling. If anyone could help me address these issues, that would be much appreciated. :)

Firefox Version 63.0 (64-bit) Home build PC, 480GB SSD, 2 x 2TB HD's, 8GB Ram.

I have had problems with streaming Channel 4 TV UK for many years. I could only get it to work on Windows. Recently I have Dumped Window 10 - so slow - updates take all day. I now am using Ubuntu 18.04 LTS (using Linux since 2009)

Channel 4 say they Do Not support Linux ?

I have tried to install Adobe Flash Player, but does not seam to work or download. On Ch 4 web page I pressed Allow, but say that I should install Flash Player !

Please could anyone advice me what I can do, or what I have done wrong.

Regards, Richard.

I have been crashing for a week now, ever since Firefox updated to the latest program. I have tried all the suggestions...Safe Mode and unchecking Hardware Acceleration. It still crashes. It even crashes when I am on my home page trying to read the news. No matter what I'm doing, it crashes. And, of course, I have to start all over again once it does. I must have 40 crash reports since the update. I'm so frustrated that nothing works. Does anyone have any suggestions besides chucking Mozilla and changing my browser to something like Chrome of I Explorer? I've been with Mozilla for 20 years and rather stay with them. Thank you in advance.

Hey all.

I am looking to download the Firefox 52 ESR (at least I believe it's supposed to be 52, I dunno if it's 52.0 or one of the later builds) which is said to still work with Windows XP, in the hopes of getting Youtube working again as version 28 works fine on everything BUT that as mentioned here: https://support.mozilla.org/en-US/questions/1234282 , however I am extremely pressed for space on the Primary drive marked C:, which has me worried about downloading and installing a new version onto my primary internal hard drive. However I have two internal hard drives, C and W. Can the ESR be loaded onto a different internal drive (i.e. the W drive), and if so, will it be considered separate from version 28, which is my current version of the program, effectively allowing me to run both versions if I wish to? I know there is supposed to be a way to set up "profiles", which supposedly allow people to run multiple versions of a browser, but I'm not clear on how to do so as I am not a Tech guy. What I would need are pretty much simple, idiot proof instructions, on how to do this, so that I can either have both versions capable of being run, or at least be able to install the new browser to my second internal drive which has ample space to handle everything that the browser requires, space wise.

At one point with this new firefox headache I managed to get my tabs on bottom but I had to do a refresh in order to get into my outlook email cause of a glitch.

Now I can't manage to get my tabs to go under the address bar. I did the whole chrome folder with the userchrome.css thing but I still cant get my tabs to go below my address bar.

Anyone have any idea what is causing this?

Its driving me up the wall not being able to have the browser how I want it.

I have three addons installed. I can see and use them from the address bar. However if I click tool/addons every category (extension, themes, plugins)is empty. Where did they go?

Firefox 63.0...when shutting down cookies/storage is not being automatically removed. Further, when reviewing the Preferences page, trying to delete cookies from there does not work either.

However, clicking on "History" in the Menu bar and then removing history from there DOES work.

Clearly this is not right.

FYI, I have read many possible solutions and have found nothing that works. I have tried using a fresh Profile and have just done a complete uninstall/re-install and the problem still persists.

I would appreciate a solution to this but it looks like a "bug" to me.

For years I've used a userchrome script to show multiple rows of bookmarks, but it no longer works in Firefox 66!

Does anyone know what's gone wrong, or a way this can be fixed?

I cannot function without multi-row bookmarks! I have over 25,000 bookmarks, all neatly organized into folders across five rows of bookmarks. there's no way I could cram all those categories into one single, solitary row.

It's a shame that Firefox has never seriously supported the bookmark bar. It's always been buggy, ugly, cumbersome to use, and never felt very "solid". The menu also has a tendency to disappear, making it hard to organize and drag bookmarks and folders around.

The search bar setting is set to "Use the address bar for search and navigation", I don't want to use "Add search bar in toolbar", because I don't want to have the extra search field in the top part of the browser, and if I go to customize, and remove it, it just changes the setting back to "Use the address bar for search and navigation".

I've already disabled the default search engine: "Provide search suggestions", and Address Bar: "Browsing history", "Bookmarks", and "Open tabs" options.

I want to be able to type an address in the address bar, without having any kind of auto completion options, but right now when I try to type and address like google for example, it still shows two lines with visit and search options, and it says "search for google with:", then shows icons for a bunch of different search engines.

I used to use firefox but stopped using it a while ago when they made ridiculous changes to it, and I'd like to use it again, but I don't know how to disable the address bar auto completion settings completely. Is there a way to fix that? Thanks.

The only video that will play is youtube. All others, Fox News, Townhall, Amazon [on product page, not Prime video], etc, do not play. I have done all that is available in the help section, none of it worked. Error "invalid mime type" From CBS OS - Windows XP SP3 Firefox ESR 52.9.0 (32-bit)

Hi, until about a month ago i could play any video on any site , i think firefox was using flashplayer then. Lately i can't play a lot of videos on line it keeps wanting to open them in another tab with VLC player which is time consuming and most inconvenient. i have tried a couple of different versions of flash player and firefox but still the same problem. i am using windows xp sp3. thanks

I accidentally deleted all my saved passwords in Firefox while intending to delete only one password.

I have Firefox version 52, with Windows XP. All of the solutions I have found online so far only apply to later versions of Windows (7 and beyond). I understand that my logins.json file is the one which needs to be restored to its earlier condition, but I cannot find any way to do this in Windows XP.

Immediate help requested. Thank you in advance for your assistance.

After updating from 67.0 to 67.0.1 the amount of space FF uses on my HDD went from 1.6 Gb to 1.3 Gb. Chrome takes up 433 Mb. How can I reduce the size of FF without losing al my passwords and login ingo.

The more tabs I open, the narrower they are to fit in window, right? Right.

But it used to work the way that when I close multiple of them, they stayed the same size for a second or so which meant closing multiple of them in a row was much easier (just click in the same place multiple times), right?

Well, it used to (work that way) because it doesn't anymore. Tabs are resizing instantly which is annoying. Here's my question: is there a setting in about:config that got resetted or something or FF70 doesn't have this function anymore? Thanks!

This is Firefox 52.0.2 32 bit ESR, Solaris 10U13 Sparc, on a 2.75 GHz. quad core Sparc VII Sun M3000 from a Sun Ray 2fs thin client.

ffmpeg, libx264 and libx265 have all been installed from https://www.opencsw.org/get-it/packages/. Flash 11.2 r202 is also installed.

A look at https://www.youtube.com/html5 shows all six boxes under "What does this browser support?" are checked. The box "The HTML5 player is currently used when possible" is also checked.

I can play some videos fine, for example this H264 test page: http://www.html5videoplayer.net/html5video/mp4-h-264-video-test/

(Actually, there's no sound but this is a Sun Ray audio issue, not Firefox).

All three of the test videos here: https://www.quirksmode.org/html5/tests/video.html also play OK (or they did before the author of this page removed the files).

All three test videos on this page also play OK: https://tekeye.uk/html/html5-video-test-page

Some Youtube videos also play fine, like this one: https://www.youtube.com/watch?v=fyuWDANi7Y0 or this one: https://www.youtube.com/watch?v=H77m14Du9O0

The right-click "stats for nerds" shows they use avc1 and mp4a codecs.

But any video that uses vp9 and opus codecs does not play. It just sits there with a spinning circle on a black background forever. And that seems like the vast majority of videos on Youtube.

In fact avc1/opus videos on Youtube also fail to start. This happens even with all FF add-ons disabled.

Oddly on cnbc.com, the small preview window videos play OK but when clicked to full-size, they just give the spinning circle. (I can't tell what format those are).

Is there any way to get these opus videos to play?

(GEES I HAD this whole thing typed, THEN got the prompt to confirm my emai? NOW IT IS ALL GONE? Holding out little hope.)

So fine. RE typing.

Earthcam all went black several weeks ago. Not one will load.

Old OS here, (mountain lion.) So firefox is version 48.0.2, the highest I can go without suffering with Apples later OS versions.

I tried with safari too. (BOTH worked then both stopped at the same time.) I have two computers. The one I'm on now has just had the latest flash update installed, and the latest java. The other has not and both have the same issue.

Tried starting firefox in safe mode with all the adblockers off... same issue.

I even just tried using my phone and got the same black screen.

Could this be something on AT&T's end? Someone posted in their forum that once they get away from home earthcam works. I don't see how, wouldn't a phone still use what ever ATT tower is nearest? Or could this possibly be specific to MY local tower?

Other videos work fine. youtube works fine.

Lastly, if earthcam is flash based, what are they going to do when flash goes away for good by 2020?
