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

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

Even after numerous Uninstalls and a Reinstalls I keep getting this error notice when trying to open Firefox...

The application was unable to start correctly (0xc0000022)

I've received my new PC and will be migrating from my old PC (Windows 10) to the new PC with Windows 11.

I use local folders in Thunderbird to keep various projects separate and more easy to manage. I have copied the current Thunderbird profile on to an external hard disk, I have found the location of the local folders and they reflect the structure in the Thunderbird screen I see. Thunderbird has been unstable for a few weeks so I would prefer a clean install but don't want to lose a lot of content that I still need.

1. Is there a way to copy over just the local folders, eg export them, rather than the whole profile? I deliberately haven't cleaned the server recently so that I can get back emails that still are in the in_tray but once they are in local folders they disappear from the Yahoo server. 2. Is there anything else significant I should be aware of before migrating? There is a backup on Mozilla but I prefer a clean install.

Thanks in advance,

Anne

looks like a problem with Firefox as no problem when using a different browser e.g. Opera. Also cannot log onto Nextdoor.co.uk using Facebook to log on. Again works fine on Opera

Any links from rcsearch.ru to aliexpress is broken in firefox, but works in another browsers. For example click any aliexpress link here rcsearch.ru/-c48920.

Concurrent with the most recent automatic windows update (may or may not be the problem), Firefox with duck-duck-go will not go to almost any site. All I get is a spinning icon or a blank page, not even any error messages. This was even true trying to go to this page until I restarted in trouble shooting mode. Until I can get Firefox working again I have been using Chrome with duck-duck-go. Note any search, i.e. 'hotels in Italy' or even 'MSN' do the same: spinning icon or blank page!! Any help would be appreciated. Also I noticed that my bookmarks were missing and there was no bookmarks drop-down on my tools line. I have run malware bytes and it showed clean, same with CCleaner. I have re-installed Firefox; no difference. Please help. and also, any way to find and replace my extensive bookmarks list? I have reduced my privacy to near zero and turned off firewalls and all limits I could find while testing for that. That did not change anything.

Hi,

Occasionally when downloading files on Firefox, they'll freeze completely (often at the very end.) There is no way to pause or cancel the downloads, except to restart Firefox.

When I attempt to restart Firefox, it closes the browser window. However, when I try to reopen it, I get an error message stating that Firefox is running but not responding. The 'Close Firefox' option does nothing, except make the box pop back up a moment later.

I can't kill the Firefox process in Task Manager or Process Explorer, because it says access is denied. I can't kill it using taskkill in command prompt because it says there is no running instance of the task.

The ONLY thing that seems to help is completely restarting the computer, which is getting frustrating to do several times a day.

I can confirm Firefox is up-to-date. Any tips are appreciated, thank you!

I always want the address bar suggestions to start with my bookmarks. Is there a way to control the results? I remember there was something in about:config previously.

I've been having issues with the websites that I commonly go to no longer appear on the autosuggest list. Websites I haven't gone to for ten years appear when I type in a given sequence rather than more common ones. Website that I go to every day no longer appear.

Multiple websites suggest this sequence:

I follow the "clear all.." and nothing changes. How can I start anew and have FF re-learn my url history?

Dear all,

We develop a system on D365 platform. On Chrome enviroment, I click the export option, it will download the excel file, I can open it on Excel. However, I click the export option on FireFox, it will download the excel file but I can't open it on Excel. When I use the notepad to open the file to see the content, I found the file become HTML content. I can see the file on web broswer. I don't know why the file content will be change HTML content when I use the Firefox to download it.

Please help....

As of an hour ago suddenly all of the usual suggestions and autofill with bookmarks in my address bar are wrong and out of order. I didn't close out of or update Firefox, I was just browsing online. I didn't change anything in my settings or have opened that up in days at the minimum. I cannot figure out how to either revert back or tell Firefox to not show me these choices so I can get my old ones.

I'll give an example: When I typed in "ma" it would show me mangadex.com, which I often go to. Now when I do it not only is 5th on the list it shows up and fills in "https://www.manticgames.com/", which I don't have that specific page bookmarked. I have "https://www.manticgames.com/games/kings-of-war/" bookmarked, but not that homepage. But now all of a sudden it is showing me the homepage of that site when I begin to type in "ma".

This is incredibly irritating and I have no idea why it's doing this at me out of nowhere. I don't want about anything showing up besides my bookmarks and specifically only the pages I bookmarked.

There used to be 4 root folders in my bookmarks toolbar on PC: bookmarks toolbar, bookmarks menu, other bookmarks and mobile bookmarks. Recently I noticed the "mobile bookmarks" folder is gone. That is where bookmarks saved in the default folder on mobile were synced. What happened?

After the last update my primary password prompt box is outlined in red. It was never outlined in red before the update. I cannot find any information for this issue. Anyone else experiencing this anomaly (at least it appears to be one since no one has reported it). Thanks

I just installed Firefox v125.0.1 on my new desktop and I am constantly being harassed by Firefox suggesting "tips" to me that I don't want nor did I ask for.

Such as this example below, see screenshot. I am browsing the web and needed to open a new tab, and immediately Firefox thinks it is okay to harass me with something that I OBVIOUSLY already know...... searching google from the address bar.

So now I have to stop what I am doing to click the "Okay, Got It" button to proceed. But, that won't stop Firefox from harassing me with the EXACT same tip in a few minutes from now.....

This isn't the only "tip" it harasses me with. It's just the only one I have managed to get a screenshot of for now.

How do I permanently disable this crap?

I have been using the internet and web browsers for 30ish years now. I'm pretty sure I know how to use an address bar by now Firefox.....

I also don't appreciate being harassed by things at all. Since this does the same "tips" repeatedly and they never stop it is absolutely harassment. Why are you showing me ANY tip more than once?????
