Firefox won't show photos on Yahoo websites. I'm using Windows 10. I can see the first photo of an article but the rest of the article shows blank rectangles. I've researched this online, and I see that more than a few are having this problem. I finally exported my bookmarks and deleted Firefox, using the Programs section of the Control Panel. I followed instructions from a "Sunshare" website. The instructions also said to go to File Explorer > Users > Isumsoft Li and remove a couple of app data files - there is no Isumsoft folder though. I'm also instructed to go to Program Files and remove the Mozilla Firefox folder, and there is no such folder that any of my searches show.

So anyway I deleted and reinstalled Firefox, restarted my PC, and I still have the same problem. I'd definitely like to keep using Firefox because of privacy but I'll have to find another browser if I can't get it to work.

I don't know why the upgrades I've installed won't address this problem, but that's not relevant to this post. Can anyone tell me how to fix this? Greatly appreciate any help here.

Hello

i have been having an issue with my browser where when ever i close it logs me out of all the websites i have been logged in to. i have refreshed it and i have reinstalled it and i still have the same problem and its making it really hard to work. any input is really appreciated.

thank you.

I received a Firefox update message (refresh) last night. Without hesitation, I clicked. I was updated to Firefox 83.0 (32 bit). (FYI-I'm still using Windows 7.) Immediately after, I realized all of my logins and passwords were gone. A "Please enter you primary password to view logins and passwords" banner is at the top of the page. When you hit the login button, the banner disappears. (I'm already logged in.) I'm left with a "no synced logins found" message. I'm always signed into Firefox when I use a browser and save login information. Not to mention, the were there moments before I hit refresh.

Of course, I don't have passwords stored anywhere else and need to access a site sooner rather than later. (whomp, whomp) I've seen "logins.json" and "logins-backup.json" files mentioned in other posts. Is it safe to assume these magic files hold login/password information? If so, where do I upload?

Any help would be greatly appreciated!

I use firefox 83.0 on Ubuntu 20.04. Browser does not play videos on Twitter, Reddit or Netflix. Youtube plays some videos but some videos show error "your browser does not currently recognize any of the video formats available". I cannot find any viable solution. what should I do?

I installed chrome and it plays all the videos. So there must not be any problem in OS.

Hi there!

Firefox 83 for some reason adds a green mask on some pictures on web pages and on some icons in tabs bar. Open picture in new tab does not help. Reinstall firefox does not help. Open picture from local computer gives nothing - green layer and weird colours

Windows 7 x64, Firefox 83

I have a piece of code which has worked fine since I wrote it almost 20 years ago and which has only been fine tuned as the standards for JavaScript have been refined over those two decades. The functionality is to act when the user stops typing into a textbox for 0.9 seconds, which by trial and error I found was fast enough to act without premature invocation because the user was just typing slowly.

```javascript // in the initialization code element.addEventListener('keydown', onKeyDownName); ... function onKeyDownName(event) {

   if (timer)
       clearTimeout(timer);
   timer   = setTimeout(update, 900);
   alert("nominalIndex.js: onKeyDownName: timer=" + timer)

} // function onKeyDownName

function update() {

   alert("nominalIndex.js: update:");
   // perform the function

} ```

The alerts are only inserted, on my private test site only, to try and debug why this code is no longer working. Each time I type a character I see the alert "nominalIndex.js: onKeyDownName: timer=nnn" but no matter how long I wait I never see the alert "nominalIndex.js: update:". To get the function to work the user must take some other action which causes the function update to be called. There are no messages in the log to explain why the timer isn't popping. How can I debug this?

The code works on Chromium 87.0.4280.88 but doesn't work on FireFox 83.0 build id 20201112153044. I am running Ubuntu Linux 20.04

Firefox blocks a bank account. Bank says it is not their fault. Bank account can be accessed using a different browser. Bank account can also be accessed using Firefox on another computer. Tried to refresh Firefox and gained access to the bank account but it worked only once or twice before Firefox went back to blocking it.

Around midday, today (08 Dec 2020), a tab in Firefox crashed. Afterwards, any open Firefox window or tab would not respond.

I closed all sessions of Firefox, and confirmed all were closed in Task Manager. Then, any attempt to launch Firefox produced a spinning circle for a few moments, and then nothing. I did extensive searching and did all the suggestions I found. Installing/reinstalling did not change anything. I moved my profile to another location, and tried to launch Firefox (without success), and a new profile was not created. The Profile Manager would not launch. Firefox would not launch in Safe-Mode. I uninstalled Firefox and manually removed all folders and ran Ccleaner to clean up the registry. I then reinstalled without success.

I tried to roll back the system to a previous restore point of 03 Dec 2020, but that was unsuccessful; there was a suggestion from Microsoft that my antivirus was preventing the restore from being successful. I disabled BitDefender and tried to restore again, with the same failed result. I ran "sfc /scannow", which found some problems and fixed them. After Rebooting, I discovered that Firefox launched and worked as expected, but then realized that BitDefender was disabled. After enabling BitDefender, Firefox doesn't launch.

I added "c:\Program Files\mozilla firefox\firefox.exe" as an Exclusion in BitDefender, without success.

When trying to roll back the system, the feature to scan for affected programs showed I was using Version 69 of Firefox on 03 Dec 2020.

Did I receive a Firefox update today that caused Firefox to not play well with BitDefender? or is there something else suspected to cause BitDefender to prevent Firefox from launching?

I am running 64-bit Windows 10.

Firefox won't play any video, on any website at all. I get different error messages on different sites, such as: The video playback was aborted due to a corruption problem or because the video used features your browser did not support OR Sorry, we're having trouble with playing this video. I've tried following some of the advice in the forums here, so I cleared the cache and the cookies, I ensured DRM content is enabled, and I unchecked the 'Use hardware acceleration when possible' option under preferences. None of this has made any difference. I also restarted firefox and installed an adobe flash player add on. Still no success. Any advice?

I have tried re entering all my data, user name password etc but still it fails. Tesco "help desk" suggest changing my browser. (Why not reinstall windows at the same time ).. so no help there.

Anyone have a thought as to what I can do?

Hi Folks,

I'm using Firefox as my daily drive Browser, nowadays I start to face a issue, trying to load a page, Binance, when I go to the Site, this one doesn't load at all, bunch of elements stuck during the load with the error message [HTTP/2 403 Forbidden 279ms] (take a look to the attached file).

I clean all the data (Cache and Cookies) in Firefox, but still facing the issues, So, I tried with different Browser, In this case, Chrome, and the page load Properly without any problem.

So, what could be the problem? if anyone have been face the same problem or something similar?

Note: I used before the site without problem.

i am unable to download full web pages such as login pages to web sites. for example, I can download the home screen for online banking but the screen comes up completely blank or missing the usename/password boxes. This condition occured without any changes on my part. The same websites still operate normally on other computers at home. Most website downloads just end up with a blank page and the mouse pointer circling around forever. This is a relatively new PC with no other issues till now.

hello everybody, i have problem when i try to join to a "MEET" conference with my account firefox, it dosn't work at all, from my laptop or my desktop, neither if i login my firefox account from a friend computer using firefox browser... When i try to join a conference, firefox open an new tab, something appears in that tab that seems to join/load the conference tools, but everything desappears in few seconds, the page become all blank and i can hear a sound that probably means that something has gone wrong.

But if i try to join the same meeting from same computer with a different firefox account the join works well, can anybody tell me what is going on?

For the last few weeks, every time I try to download a file, doesn't matter the format, if I chose "open with", it acts like it downloads. However, when you check the downloads, it just reads {filename} - File moved or missing. And it doesn't show up in my downloads folder.

If i select the option to save it first, then i get the downloaded file and can open it.

I've uninstalled Firefox multiple times, reinstalled, tested with both the normal public installer and the enterprise msi installer. I run no extensions or plugins beyond what's there by default. I've deleted the default profile, created a new profile. Tested in safe mode.

Though i can still get what i need, it's a little cumbersome when i have to download a bunch of default reports or files with generic names and clutter my downloads folder.

Some weblinks and websites are being unresponsive in Firefox 83.0. I don't mean that I am getting an error message when I click on them, they are not responding at all.

Anybody else having this issue? It is only some websites and I have confirmed that I can visit them in other browsers. I flushed my cache and that did not fix the issue.

My MacBook Pro is running OS 11.0.1 and using Firefox 83.0. My battery runs down faster than it used to. Apple suggested checking the Activity monitor and I noticed several instances of FirefoxCP Web Content. I have lots of tabs open. Most of them are using <1% of CPU, but one is about 50%. Is there any way to figure out what that is other than shutting down the tabs one at a time and watching the Activity Monitor?

I got this message when clicked on a link within my online banking site after I had logged in. It was followed by a reference to Javascript and the suggestion that additional software may need to be installed. As suggested on forums I restarted Firefox with add-ons disabled (safe mode) but the problem persisted. I have Javascript enabled in Firefox.

I tried in MS Edge and had no problem with this.

Here is the link I am having trouble with: javascript:callAjax('/AUGCB/JBA/mmInit/flow.action','COAAppLayout');

If someone has an idea how to fix this please let me know?

On new laptop with Windows 10, with an external monitor in extended desktop mode, Firefox is opening partially off screen such that the top bar is inaccessible so I cannot drag it back on screen. If I close it and reopen, it will usually be back on screen. How can I fix this?

Perhaps related: tabs are not reopened and Restore Previous Session does not work.

There are no extensions open.

Thank you for assistance.
