Firefox won't display background video on my website http://iconx.tech/home-1-8/ while other browsers do it seamlessly. Kindly fix this issue, or I regrettably needs to point out to my audience that webpage has been reported to break on Firefox and advise them to use Chrome or other browser.

Thanks and kind regards.

Windows 11 computer. Since 2 days Firefox and Thunderbird have stopped working. I get a blank browser and a Thunderbird without my emails. All other browsers still work and Firefox also works on my smartphone. I have followed the suggestions on the Support website, but nothing helps. What now?

We have been maintaining a set of tools for Science Olympiad Code Busters (https://toebes.com/codebusters/) that generate and print tests.

When we print the tests using other browsers (Chrome, Edge) we are able to get consistent formatting and output such that the page fits on the sheet of paper and text is rendered cleanly. However, in the past year or so we have received complaints from Firefox users that it doesn't format and print well.

I was able to confirm that it indeed produces less than ideal output with Firefox and spent several hours to reduce the problem to a single self contained file that I have run through the W3c validator to ensure that there is no un-toward HTML.

I've been able to reduce it down to a small example that has everything contained in a single file: https://toebes.com/codebusters/Samples/firefox_toebes_printing_example.html

If you load the file in Firefox and then print, you will notice several issues: 1) The names of participants table ends up wider than the page. 2) The Score table on the first page is off the right hand edge of the page. 3) The header for the second page (Page 1) is on a page by itself 4) The footer for the second page (Page 1) is near the top of the third page 5) The text for the timed question appears too high on the page 6) The text for the timed question is in a slightly larger font such that it wraps early. 7) Similar problems are on the last page, with the header appearing nominally in the correct place 8) The footer for the last page is on a page by itself.

Note that I have experimented with multiple options for the print scale and margins, for purposes of comparison I set the margins to .5" all around and forced the scale to 100% in all three browsers.

Is there some other option or tweaking that I am missing to get this to work properly on Firefox?

If there's an internal scroll bar for something within a website, Ancestry is a good example of this, I've had to stop using Firefox for it entirely now, you can't get to it, because every time you try, the Firefox one pops up over the top of the internal one. I can't work out how to deal with this, there's multiple sites I use regularly that I have to open in a different browser just to use effectively because of this one issue.

Prior to today, on my Edwards Jones site, I could click on market commentary or check on latest CD rates and see results. But today, you have apparently changed the way 'embedded sites work and it traps an error. Right clicking on the link does not work ... So this obviously your latest new and improved feature to protect my security does not work as intended . . . what are you going to do to fix it?

I moved the downloads folder via File Explorer to OneDrive. So now it's like this:

c:\users\[username]\OneDrive\Downloads

But Firefox keeps wanting to save files to the original location:

c:\users\[username]\Downloads

All other apps seem to respect this setting other than Firefox. Any ideas?

FF 128 on Windows 11 23H2.

Updated my Win 11 laptop with latest changes and find the fonts on pages and on tabs is all messed up. I've tried Settings to choose larger size, set defaults to Arial and/or Arial Round .... does not help.

How do I either fix this, or undo this update, or is there a fix coming ASAP??

Hello! Since 9th of july web version of telegram app doesn`t work. Please, help to solve this issue. Mobile version of telegram works fine, as a web version in another browsers, except Mozilla. In attached file you can see how telegram displayed in Mozilla.

Thank you

So, I use Fn + F7 which should stop or play the last active audio source.

Sometimes it works, sometimes it just refuses to work for one site at time, while the others work fine. So, for example, I have site x which plays audio, and site y which played audio some time ago, both windows open. Sometimes medias keys work as supposed, sometimes it doesn't work for site x for no apparent reason while it works for site y, or vice versa.

To get it to work, I have to spam it, move the tab around to the front (sometimes it works, it seems it gets priority, but it could be just coincidence) or completely close the tab and open another one with the same site. Whatever's causing this, it seems to be random, but it seems to be caused the most when having multiple tabs that can play audio, but not exclusively.

I just switched to Firefox and I don't really want to switch back, so it'd be great if any assistance is offered. On my last browser this wasn't the case.

This is what I've tried to solve the problem, but didn't work: - Go to about:preferences and turn off and then back on media.hardwaremediakeys.enabled - Open your Firefox settings (about:preferences); Uncheck Control media via keyboard, headset, or virtual interface. It is at the end of the page; Restart Firefox; Check that setting again

Additional information: - Here's the site that causes me trouble the most (this is a YouTube playlist loader for big playlists): https://youtube-playlist-randomizer.bitbucket.io/ - I use Windows 11

When I log into Tesco, it will not load and says, your browser(firefox) has failed security checks. I am using Norton 360 and run a full scan with no indications. All other apps and icons load using Firefox. Tesco refuses to. I have removed it and re-loaded it several time. I worked well untill yesterday when I did some routine windows updates.

Hi, got a problem for the last several days - on each visited site Firefox (my guess) is launching a pop up about add-ons for Ad Blocks tham I am using were updated with official national filters for Polish market.

This is super annoying and the pop-up jumps on almost every new site bieng visited (it is visible for ca. 5 seconds). Is there any way to stop it? How can I dissable this feature?

Thanks, r.

I get the message:- Oops... It looks like something is not right

If you are seeing this page it is because your browser has failed some security checks. You may still be able to browse our site to find the feature or store you're looking for.

The Tesco website works OK with Edge on the same machine and Firefox 127.0 on another machine. I think this is a known problem is there a fix/work around?

I've just reinstalled Windows and Firefox browser so how can I get back my Synchronized bookmarks??Are they all lost?Because I sing in and trying ot synch but nothing changes.Thank you.

Hi I have lost all my bookmarks. I bought a new device. On downloading Firefox the the bookmarks toolbar was Google's. Now Firefox on my other devices has the the Google bookmarks toolbar. Help please.

Hey guys. Just bought a new pc with a RTX 4070 ti super GPU. FF is my browser, and when i google i see VSR is supported in FF. But watching videos in FF does not activate RTX VSR, it stays inactive in the Nvidea control panel.

When i use Chrome browser it works as it is supposed to, it says active and i can see the video quality is improved. Is the feature just broken in FF at the moment, or is there some settings i can change in FF to make it work today?

(i checked about:config and gfx.webrender.overlay-vp-super-resolution is set to true)

When I try to open an eMSN link in my Medicare account. It says that" Website will not allow Firefox to display the page if another site has embedded it" I tried right clicking on the eMSN link to open it in a new window but that results on the same message. Thanks for your help.

My PC uses Windowss 11 and I'm on Mozilla. My security programs are Malwarebytes Premium, Windows Defender.Security, and Acronis. There is an Extension called, 'Protect My Choices'. Love It! I have it on all my Browsers. It keeps alot of junk off from my PC. In all my other Browsers, in the Extension details it states "Automatically allow access on the following sites:" I just don't move the button over to on, and the Extension keeps all that junk off from my PC. In Firefox, the above statment and the botton is absent, and all that junk is allowed onto Firefox (Yikes!). I went through Mozilla's Help, Troubleshotting, and Search. I haven't been able to find any clue as to how I can get this Extension to work in Firefox. Any assistance in this matter will be greatly appreciated. Thanks so for your time and consideraton of my sad saga

Hi everyone,

Firefox started becoming extremly slow on certain websites, which I have bookmarked. It goes through periods of that. One it was because of a plug in, other times I would think it was a virus of my internet provider slowing it down. But it became really slow this week, and I started noticing what it says on bottom of left screen when it's loading.

I kept seeing "contacting googleadmanager.com, read.tags.tigcdn.com, contacting highfalutinhoney.com." There were other various ones that have started read.tags, but those were the main ones I thought it was a virus, and kept doing virus scans with Norton, Malwarebytes, and making sure all software and computer, was updated. The only thing that helped was deleting profile in the profile folder on Mozilla and deleting it on my computer, and redoing all settings, with nothing imported.

It hasn't been slow in awhile. The only thing I can think of is I went on google maps, and saved a bookmark of a place on Firefox, and the offending website that was really slow was also bookmarked. Is it possible because I added a google bookmark, it installed on my brower tracking cookies? I set to have the settings to strict for my browser, never remember history, and use duckduckgo for search, except when I went on google maps this week on a private tab and then bookmarked a page from google.

If anyone knows how this happens, I would really appreciate it :} I don't know much about the technical stuff for computers. I'm just a basic user.

Thank you

As of 7/10/2024, I cannot sign in to ATT.com via Firefox. Other web browsers work correctly. The site generates a "902" error (proprietary). In the console, I see a failure to load 2 scripts:

Loading failed for the <script> with source “https://signin.att.com/static/thirdparty/adobe/detm-container-hdr.js”. LrrController:33:2 Loading failed for the <script> with source “https://signin.att.com/static/thirdparty/adobe/detm-container-ftr.js”.

Note that I can click that link in the console and each of those scripts loads. I have tried disabling tracking protection for the site as well as disabling the adblocker.
