Help -> About "Failed to check for updates."

This has been going on for over a week. I have downloaded and applied the installation program multiple times (>3). The problem persists. What is going on, and how do I fix it? Thanks

In the last couple of days I've been unable to login to my virginmedia accounts using firefox, all other browers work fine, I can enter details no trouble but as soon as I press the blue button on their page nothing happens, cleared cookies and data for virgin but didnt help.

I often like to have 2 browser windows open with multiple tabs going on each window. Recently, however I noticed that whenever I watch a video in full screen mode on one monitor then I switch focus to the second browser window to do other various activities, the video playing on the other monitor will sometimes exit out of full screen mode and continue playing in the original embedded small screen size. So far I've tried disabling all but the most essential extensions, put the theme back to the default mode, made sure my graphics card is fully updated, and even attempted a few setting changes people have recommended for fixing similar issues, but nothing seems to work.

As of right now, the only workaround would be to use the picture in a picture mode and put that to full screen, but that isn't ideal as picture in picture mode is set to be "always on top". I could also use a different browser, like Chome on my second monitor which doesn't seem to cause the video to exit full screen mode, but again, I typically prefer to use firefox for most things online.

Anyway, I'm now out of ideas on what to try to get firefox to behave in the way I want it to.

Hi and thanks for your help. I was playing around with my DMARC settings for my new site and was looking around at who was hosting my WordPress domain for http://ibizignite.com, and Google directed me to GoDaddy. That was wrong. However, in my fooling around, somehow GoDaddy and this associate Westechnologies keeps popping up when I open up my browser after booting up my computer, and I cannot get rid of it. I don't know where to find it, because there is no associated extension anywhere in my extension list.

Here is the address that came up: moz-extension://dfdaa01e-fa7e-4241-8590-a19edb2ec40f/data/blocked/index.html?url=https://www.godaddy.com/forsale/www.westechnologies.com?utm_source=TDFS_BINNS&utm_medium=parkedpages&utm_campaign=x_corp_tdfs-binns_base&traffic_type=TDFS_BINNS&traffic_id=binns&

I tried to use another add-on to block it, and it does, but the darn site keeps appearing every startup after a fresh boot, and neither Westechnologies not GoDaddy appear anywhere in my Zone Map or anywhere else in my registry. Can anyone help me get rid of it please?

When I open the Manage Bookmarks in Firefox I have thousands (not exaggerating) of recently bookmarked items. How to I delete all of them? I think I turned that feature off via the browser.bookmarks.showRecentlyBookmarked. I changed it from True to False I have tried deleting them one by one but it seems like they recreate and I am not making any progress deleting. How do I delete all of them?

Thank you.

The box in Settings > General > Startup > Open previous windows and tabs is still unticked.

Does anyone know what could be causing it and how to fix it?

Thanks :)

I use a public computer that resets itself every night. I want to login to my firefox account so I can receive all my settings, extensions, etc., when I login to sync.

However, when I login to sync, my default search provider remains as Google (the computer's default) and does not change to DuckDuckGo (the settings I previously had synced).

How do I set up sync so that when I login, it pulls all settings, etc., from the cloud, instead of keeping some that were configured locally?

For the last few days the ebay website is very slow when I open it. If I switch to Chrome, ebay's website loads okay. All other websites seem to load through Firefox with no problem. Any ideas???

Hello- I am having a very strange thing when using Firefox. I type and certain letters pop that I have not typed. It is different letters that are affected. it has been the E a number 2 shows instead s a m shows instead. There have been others but I did not make note, My solution is to close firefox and reopen. I have updated to newest version. Do you know why this is happening and a better solution. Also when I go to Chrome the letters do not transpose. HElp Stephana

When I went to watch Tubi TV today I got this error message when I tried to load the video:

"Oops, your web browser is no longer supported. Please upgrade to a modern, fully supported browser."

But only for a few seconds, then it shows

"Sorry, there was a problem loading the video player. Please try to reload the page. If you are using an ad-blocker, please disable it or whitelist tubitv.com If the problem persists, please contact us at tubitv.com/support"

I booted my firefox in safe mode, still get this exact sequence of events. My firefox is up-to-date. Is there a workaround for Tubi blocking content from firefox browsers? Is that what this is? Thank you

Firefox browser problem. When dragging the mouse over text on a webpage to select text I want to copy, some of the selected text and an area of webpage adjacent to the text I'm trying to select is blocked by a box that automatically appears. Sometimes it whites-out a box-shape but usually it's blacks-out. This blocks that part of the page and some of the text I'm trying to select while I'm dragging my mouse and I can't see the mouse while I'm trying to select text within that box. What did I do to cause this and can I change something to make it stop? This is only when using Firefox and I didn't have this issue until October 2023.

Ever since about a week ago, my Firefox just started... bugging. Twitch doesn't work, now Netflix doesn't work, basically anything that plays videos (except for YouTube) doesn't seem to be working.

On Twitch, if a person is live and streaming, upon clicking their stream to view it, it's suddenly offline, even if the chat is going and the "this person is live" notification is there. Netflix gives me a f7351 error. Websites with online media (like free movies on putlocker) have multiple streaming services attached and neither of them works.

I've cleared all cookies, cache, data and history.

This is only concerning Firefox, other web browsers work perfectly.

Extensions on my Firefox are as follows: BetterTTV, Dark Mode, DocsAfterDark, Facebook Container, FrankerFaceZ, I don't care about cookies, Instagram Dark Theme, New XKit, TinEye, Tumblr Saviour. No adblocks, no nothing.

My operating system is Windows 10, 64bit, Firefox is updated to 119.0.1.

Any help would be appreciated as this has been the bane of my existence for a while.

Tabs always start in mute mode. I can turn it on by pressing speaker logo in the tab. The problem is when I shift to a new tab, the previous tab mutes automatically. For example: I listen to YouTube music and want to check my mail. When I shift focus to the new tab the first mutes it self. Any suggestions please. Sincerely Oscar.
