Firefox Support Forum

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

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

Longtime FF user (15+ years); just back from a few months of testing another browser and noticed strange labels for Google Contacts in FF125.0.2 (64-bit) (see attached). Any idea what's happening with that?

...and while I'm here, is there a way to choose the digital format for saved screenshots other than .png?

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

Hi, Before Firefox's Version 125.0.1 (64-bit) latest update I could download any file from my safe office environment, behind firewalls, VPN, ... Now despite of unchecking the "Block dangerous downloads" I'm still unable to download files. I have Windows 10 on my laptop.

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Thanks in advance for help, Tibor

My search box disappeared. I know about clicking the 3 horizontal lines, selecting customize and dragging the box. Actually the box is still there on the customize screen, but not in any other tabs.

Dragging a second box does nothing. Refreshing Firefox does nothing. Rebooting does nothing. Firefox 125.0.2

1. Web pages load in gibberish, they aren't legible. 2. Web pages load with neon green blocks. 3. Firefox isn't allowing me to download an entirely new download.

I understand the gibberish could be a font problem but when I use right click for inspection options, I can't find any font info anywhere. Even if I could, what would I do then? Green blocks, have no idea. I used to use Firefox and have just now started again but would prefer a brand clean copy. Mozilla isn't giving me that option. Thanks.

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?

Hello, today firefox has been appearing as a blank icon on my taskbar. I have tried solutions suggested in older posts but it did not help unfortunately. if i try to

1- right click unpin from taskbar the icon shows once more. 2- right click, the icon disappears/becomes blank. 3- click pin to taskbar, the icon remains blank.

attached is the image showing the steps i described above

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?????

Firefox 125.0.1 update breaks all self signed certificates

After the latest auto update I can no longer access any of my management screens on my private network with self signed certificates. This is a real problem. I have attached a couple error screen grabs, but ALL of themn are the same. The information link says there is no workaround!

So how do I recover access? Chrome works just fine ... so it is def. a Firefox problem.

I've just updated to Firefox 125 and now, when I start to type in the URL bar and get my suggestion dropdown of previously visited pages, I no longer can see the actual url for each entry. All I see is the top level name for each entry.

This is not helpful, as I may have perviously visited a number of pages on that site and the information shown does not give me a way to differentiate sufficiently between those pages.

How can I get the exact url displayed on the suggestions dropdown.

How can I get those top level descriptions NOT displayed, so that only the urls are shown?

I use a web application that lists items in a table, which provides a link to download the table as a CSV file. It used to work fine in previous versions of Firefox. However, in the current version, while the file save dialog defaults to a filename that ends in .csv and CSV is selected in the "Save as type:" drop-down, the data in the file that Firefox actually saves is in XML rather than CSV format. I don't know in which version of Firefox this behavior changed, as it's been a couple years since I tried to use this feature. Or I suppose it actually could be a new bug. I do know that when I use the same feature in Microsoft Edge, it saves the CSV file in the correct format, so this behavior seems to be peculiar to Firefox, rather than anything wrong with the web application.

I have Windows 11 and the Firefox 124.0.2 browser. I cannot update to the latest version of Firefox. I receive an error message "Failed to update". I've uninstalled and reinstalled the browser, ran the install utility selecting update, nothing seems to work. Please help

Prior to update 125.0.1 corporate intranet users could download PDF files from our Line of Business applications / Webpages. Today after the latest update the PDF files download but are corrupted. The site was added to the trusted webpage without improvement.

Adobe Acrobat Reader could not open ********.pdf because it is either not a supported file or because the file has been damaged
