Firefox Support Forum

Good afternoon folks I can't watch Netflix on my Firefox browser. Do you know why is there a plug-in what is missing or something? He says the version is not up to date While my Firefox is always up to date, can you help me further. Thanks in advance from Trimmy.

Hi Firefox start to take a lot of CPU depending on how many tabs are opened (that is normal of course especially if with flash contents). What is not normal is that CPU will not be released when tabs are being closed, even with one (blank) tab left opened CPU usage is 40%-85% (depending if other process need CPU). Essentially: once Firefox process obtained 80% of CPU you can close tabs but you are fucked the same, now opening new tabs is a pain! Of course restart fix the issue. Is not a matter of addons or updates, Firefox and system (Windows 10) are updated to last version; I feel is something related with flash contents. Is it possible only me experience this?! Regards

So I was having some trouble a few days ago with a website that automatically re-directed as soon as I landed on it to another page. So I happily went off in the settings and disable the automatic redirect. Now a week or two later I'm sitting here going I can't find the setting anymore? I can't even search for it and have absolutely no results you would think searching for "redirect" in the settings pain would bring it up. it's probably something that got buried in developer tools that I would never be able to turn off/toggle again unless I get lucky with the right extremely memorable and easily accessible incantation in the about : config because that's just all so well documented. Is it a "1" is it a "0" is it a "5" which one disabled / enabled what is the other options do?

Hi,

I brought my computer to Best Buy for some audio issues it was having. They reset my OS and drivers and now I lost all of my Mozilla Firefox bookmarks and passwords. I do not have a recent JSON backup file. How can I recover these?

Thanks.

Error message: E:\Users\Sarah\AppData\Local\Temp\xxxxx.xxx.part could not be saved, because the source file could not be read. Try again later, or contact the server administrator.

I do want to mention upfront that this issue is also affecting Chrome and IE. It's not solely a Firefox issue, but I'm hoping someone here can help me anyways.

• This happens for any filetype, from any source.
• It started happening about a month ago.
• Prior to that, I installed a new motherboard, RAM and processor. I'm fairly certain there was a period between these events in which it worked fine, but I am mentioning it just in case it's relevant.
• If it's a small file and I try repeatedly, it sometimes will eventually download.
• Even if a large file successfully starts downloading, it will eventually fail. It usually fails immediately though.
• I sometimes have success downloading the same file in Chrome, but it also often fails. IE as well.

I have tried the following:

• Used Refresh Firefox
• Cleared download history
• Changed download location
• Reset browser.download values
• Disabled firewalls and antivirus/spyware
• Reinstalled Firefox using Run as Admin (first uninstalled previous version and deleted all program files that I could find, including profiles)
• Cleared cookies and cache
• Ran in safe mode
• Verified Temp folder filepath was valid
• Verified the PART file was created in that path -- it exists until I hit OK on the error message, then it disappears
• Ran Firefox as admin

I think these are outdated methods I only found on non-official sources, but will mention them just in case:

• I found some sources that said to delete Compreg.dat; I could not find this file in the place listed, nor could I find it with a search of the entire drive
• Verified places.sqlite was not set to read-only
• Removed read-only from entire profile folder and subfolders

In Options > Security: 'Block dangerous & deceptive content': true, 'Block dangerous downloads': false

Internet speed test: 58.96 Mbps download; 148.04 Mbps upload. No connection loss.

This problem is absolutely maddening. I'll be so grateful if anyone can help me out!! :( Thank you in advance, I know this was a long read!

How can I change the DNS Server in FireFox to whatever DNS I want and not what Mozilla wants?

For example: Google DNS 8.8.8.8, 8.8.4.4 or, Open DNS 208.67.222.222 · 208.67.220.220

Enabling DNS over HTTPS dose not give me FULL control over this. I should be able to put a DNS IP address in there like in Internet Explore.

Hi,

The version of Firefox 68.9 on Linux CentOS 8.2 has problem playing videos from https://www.udemy.com Testing on macOS and Windows 10 the Udemy Courses are presented fine. I get dark video.

All of a sudden, my bookmarks ( and other bookmarks) are double spaced. This just happened today and I didn't make any changes. How do I get rid of the double spacing ? Thank you.

Today firsfox just stopped connecting to a wss websocket server. It has always worked fine before today and still works in Chrome.

What happened???

Port is open. Connect when running websocket.org/echo.html in chrome but not in firefox

This page keeps refreshing itself. Clicking the Refresh X stops it:

. . . since I just updated to 78.0.1 (64-bit) . . . ? It looks like a bug to me.

I'm on an older iMac using OS 10.10.5 Yosemite. I can't upgrade due to work.

Currently I'm running Firefox 78.3.1esr (64bit) and I'm having trouble seeing some websites correctly (see attached screenshot for ebay for example). Sites also take a longer time than usual to render.

Is there anything I can do to make Firefox work well again?

Thanks!

Hi! I found a strange thing today. I wanted to open an ftp link and firefox asked me in which app I wanted to open it. Of course I wanted to open it in Firefox, but the only app on list was Internet Explorer. So, I added Firefox to the list, but I couldn't open the link with it, because when I marked Firefox and tried to click "open", nothing happend and the box still appeared. So, I ended up using IE. I'm using Firefox Nightly (81.0a1 atm of encountering this).

Currently, I'm using Firefox 82.0.2 on Fedora 31. Recently, it's started opening most, but not all links in a new window instead of the current one. Not on all sites, but most. As a pair of examples, it opens links to articles on gasbuddy.com in a new window but not on Slashdot, and until a few months ago, it only opened a new window if I right-clicked and selected New Window from the context menu. I'd like to get the old behavior back, as this is quite inconvenient.

Hello. I need help with: `DOMException: The quota has been exceeded.` I'm trying to use IndexedDB. However, the code is requesting persistent storage: `await window.navigator.storage.persist();` (and this is returning true) This website is only storing about 8MB of data and I have a different website storing 200MB of data (userscript) The storage medium still has 140GB available. What quota did I exceed? If this is the wrong place, please direct me to the right place

The Firefox desktop browser is the only one that give me this error Error code: SEC_ERROR_REVOKED_CERTIFICATE I am on a MAC OS using latest version of Mozilla Firefox desktop browser: 82.0.1 (64-bit) Incognito mode, cleared everything, reinstalled the browser and still got the same error. Talked with GoDaddy support and they told me everything is ok on their side. What is going on? Why: Safari, Chrome, Opera, Firefox Mobile (iOS) and so on have no problem loading my pages, but Firefox desktop has?

I looked on my GoDaddy hosting cPanel and the SSL are correctly generated and valid, so I don't understand what is going on with this browser.

Thank you! PS - If this is already answered, please point me to the correct reply.

Today I updated my Firefox Developer Edition to version 89.0b2 and now I just can not look at this browser anymore, "Inspired new tab design" is taking too much space and now became largest and at the same time least information-dense panel in my entire desktop! I searched around the web for a bit in hopes that I will find a theme or an add-on that will revert this particular change but no luck. I really want to revert to old UI look (at least tabs bar), there should be default theme or option to get back to old style. After some investigation I found userChrome.css but don't really want to install it (maybe this is actually the way of doing this kind of styling). Please help me revert UI design to old one.

Read support article about importing username and password info direct from .CSV file. I see at the bottom of that article that if no such option presents (Import from file), I am to ensure that signon.management.page.fileImport.enabled is set to true. I don't see that operator within the listing of configuration options. I can create that operator and set it to true, but that doesn't make the 'import from file' option appear in the three dot drop down menu within the Logins and Passwords page. Has the title or location of the fileImport operator changed, been moved?

When I try to watch a video on WSHH, I get this error VIDEOJS: ERROR: (CODE:4 MEDIA_ERR_SRC_NOT_SUPPORTED) No compatible source was found for this media. I have DuckDuckGo Privacy Essencials installed, and I also have uBlock Origin installed. I disable both extensions but I still see the same error. I'm on Ubuntu 20.04 LTS, and my Firefox version is 77.0.1 (64-bit) canonical - 1.0

I attach the console log.
