So the problem is that Firefox doesn't play any HTML5 content. Weirdly except for Youtube. Youtube works just fine. But every other Website shows errors. Even songsterr.com. I'm using latest Firefox 76.0.1 on a recent Ubuntu 20. 04 LTS installation. Usual troubleshooting like updates doesnt work because "sudo apt-get upgrade" doesn't find any updates. I tried the same websites in the latest version of Chromium and they work perfectly fine. I couldn't find a mistake in the firefox settings or something so I'm confused. Disabling Plugins didn't change anything and turning of tracking protection didn't either. What is the Problem here and how can I solve it?

One feature at www.weather.com (Weather Channel) is their "weather in motion" feature which loads interactive weather radars. For some reason, this is not working on my Firefox browser. It works fine in Chrome and Edge. The weather.com website loads just fine but the radar data (overlay on a map) will not load. IT WORKS FINE IN SAFE MODE. So i tried to disable all of my plug-in's, extensions and hardware acceleration in Firefox in regular mode. Still doesn't work. I created a new profile. Still doesn't work. I disabled the tracker feature in Firefox on that web page. Still doesn't work. I uninstalled and reinstalled Adobe Flash. Still doesn't work. Any ideas???

What happened to the Arial Black font? It suddenly disappeared from the list of fonts that appear in Tools >> Options >> Language and Appearance.

Due to vision problems, I require a bold font. Mozilla has now made it almost impossible for me to use Firefox. Does anyone know of a workaround to this problem?

also, a FYI: Removal of this font violates the Americans With Disabilities law.

Firefox uses system High Contrast text color for websites

Hello, Firefox seems to be using my system's High Contrast text color to render websites. My High Contrast text color is a light grey, to contrast with a dark system background. However, many webpages on the internet have light backgrounds, so when Firefox uses this color, I can't read the text. I already have Options>Language and Appearance>Colors>Override the colors specified by the page set to "Never." This also occurs in a brand new profile with 0 extensions or addons in Safe Mode. I just want Firefox to display webpages "normally", i.e. with black text, without regard to the current system colors.

To reproduce: - Turn on High Contrast - Visit a site such as http://hyperphysics.phy-astr.gsu.edu/hbase/ppois.html - Change system High Contrast text color to any color you wish - Notice that the text on the page also changes to the same color, even with the setting on "Never"

Is there any way I can get Firefox to ignore the system's text color settings? Chrome renders the webpage just fine with black text.

Hi.

I love Firefox specifically because it lets me use Ctrl+Shift+N, i.e. reopen a closed window. I have this one window with several pinned tabs (Facebook etc.) and a few other open tabs (some reseach, YouTube etc.) where I keep things that I need to return to. I essentially NEVER close this window without reopening it, because it has the most important things I need. Sometimes I open a second/third window to work in (I had an online exam the other day, so I opened that and my materials in a separate window, so I can cycle through them more easily).

When I open this second window, sometimes I close my main window (it has quite a few tabs so it slows Firefox down). I then always reopen it using Ctrl+Shift+N and never had a problem. Well, I closed it now (then opened one or two other new windows), but when I wanted to reopen my main window back up, it just refused to. It's gone from "recently closed windows". Interestingly enough, at least two other windows I closed BEFORE it (one from yesterday, that I did unrelated googling in; the other was closed a couple minutes before the main window, it was an emoticon set that pops up from one forum) were possible to reopen, but not my main window. Now I can reopen just 3 windows, and I don't understand where they are (there used to be up to ~10 or so).

I want to know why I was able to reopen windows I closed long ago, but not the most recent one, and whether there is a way to fix this and get the main window back. I have effectively lost ~40 tabs that I had open (some research articles, pinned social media, some stuff I wanted to read etc.) that I can't even reopen unless I find them through my History (and hoo boy, that'd take a while).

Thanks for any info. Have a nice day.


SOLVED - EDIT: The amount of windows that can be reopened can be fixed as mentioned below. Lost window probably cannot be restored, sadly. EDIT 2: Actually it can be restored! See the answer to find out how. Both these lovely people gave me answers to my questions, kudos to both of them.

Inspector element highlight html element wont go away when the mouse no longer hovers

This question is about the developer tools (inspector). Sorry if this is not the right forum. If this is not the right place, please specify where I can ask this question. I have looked around but this seemed like the best place to write this.

This problem started a couple a month ago in Firefox Developer Edtion after an automatic update (to either v82 or 83, im not sure).

This is what used to be the case, prior to the update: In the developer tools, in the inspector tab. There's an overview of the HTML-tree, and when you hover over an html-element in the tree, the correspondent element in de browser window is highlighted, and when you move your mouse the item will no longer be highlighted, since you're no longer hovering over it in the HTML tree. This is how it has always been.

The situation as it has been for 2 to 4 weeks: After selecting a couple of items in de HTML tree, and maybe editing some CSS, so just after normal use, The selected element will stay highlighted, even though I'm no longer hovering over it in the Inspector window. I added a screenshot to show what I mean. This bug is annoying because when editing CSS, I want to be able to clearly see the changes I mean, but now theyre obstructed by the highlight. Toggling developer tools by pressing F12 twice fixes this obviously, but only for a couple of minutes, and sometimes the problem return immidiatly.

This problem first emerged in Firefox Developer Edition about a month ago after an update. It really messes with my workflow, and I couldnt find a solution. Tee problem emerged on multiple websites (not just the ones a was developing, as you can see in my screenshot it also happens on the mozzila website) and the problem was the same accros multiple computers (all modern windows 10 machinary, owned by me or my collegues). So I stopped using Developer Edition, and switched to using 'regular' Firefox for developing, as regular Firefox did not exibit this bug. But since last week, after regular Firefox also got an update, the bug appears in regular Firefox aswell.

So here I am, an avid Firefox Developer Edition user, desperate for a solution. Ofcourse I already tried everything from reïnstalling, refreshing firefox, everything.

Thanks

I lost over 700 tabs yesterday when FF Crashed. When it was re-opened, I only had one Tab and none of my pinned tabs were there and all the other tabs were gone. All Tabs Helper had all but about 30-40 tabs suspended and I had opened and closed FF many times in the past and it had always reopened the complete list of Tabs with all but the pinned tabs suspended. I really don't want to go into history and tell it to open all the tabs from the last month, this is definitely asking for trouble. I am posting this from EDGE so as not to screw up any chances of a full recovery if possible. Thanks, Ed

I Googled about stopping using Firefox beta and transition to release version but none of the pages I found in this forum talks about an error message about user profile that only gives me the option to Create a New Profile (therefore losing all my add-ons, cookies, settings and everything) or Exit.

I tried manually googling "download Firefox" and downloaded the release version and after installing it, I get the warning message above. This thread here https://support.mozilla.org/en-US/questions/1224888 has a link to the rapid release version but I end up in the same warning message.

Since the beta will necessarily always be a newer version than a release version, how do I transition from beta to a release version but preserve all my settings, add-ons and everything if Firefox will tell me that it won't let me use my existing profile in an older version, the release version?

My motivation to leave the beta version is that Firefox started having a bug since 27-Oct-2020 in Google meetings where either a shared screen or the camera image of the person in a meeting appears very zoomed in in the top left corner so it doesn't show the rest of the image.

It's annoying to have to delete all of that before I can enter the URL I want. How can I get the automatically blank address bar I had before? I use Firefox on a desktop Mac. (Firefox tells me there are thousands of results for this question, but I can't find any of them.) Thanks.

So this is a weird development. All of a sudden, when I try to search with Google, the "settings" and "tools," buttons no longer work, unless I'm doing a search for news. Thus, for example, if I'm trying to find an image that is on a CC license, that's impossible, or if I'm trying to find a how-to piece that's less than five years old, that's also impossible.

Also, when I do search for images, only the first few images are clear. The rest are simple blocks of color.

I don't have the problem with duckduckgo.

I'm running the latest version of firefox on a mac.

Am I doing something stupid? Which is all too likely, I'm afraid :-)

many thanks in advance.

For some reason videos on twitter (& audio posts) don't output any sound thru my speakers when played.

The tab isnt muted, nor is the volume down in windows 10's mixer, in fact the sounds even shows up as playing in windows volume mixer. but nothing comes out

Other websites work just fine! It appears to be only a twitter issue, tried opening new tabs etc & they still dont output sound :(

Works in other browsers like chrome too Any help would be appreciated!
