Hello, Firefox randomly downloaded a file, with seemingly randomly name, that is 0 bytes and in download manager the source is moz-safe-about. It happened when I was accessing a popular wiki site. I opened the file in notepad, it was empty. I put it on virus total and came back negative, as it is an empty file. I've curbed through the support tickets here, using the keyphrase 'moz-safe-about'. I understand this was/is quite a common problem, but it still makes me quite worried and left a sour taste in my mouth, as I haven't understood any of the explanations. I have enabled firefox to ask me whenever it wants to save something (I have no idea why this isnt the default state). Happened on a somewhat fresh, updated win 11 installation. I'm also attaching more information here with a picture. Long story short: should I be worried? Am I overreacting and this is just some sort of a bug that occurred while getting a sites data? Thank you for your time.

So this problem keeps happening to me - I click "upload" on a website and nothing happens. For example, trying to upload photos to my website or upload files to a platform. Frustrating. To work around it I've been using a separate tab of Google chrome but it's such a pain to keep swapping back and forth. Please help!!

Hi I am a longtime user of your browser. I have version 124.0.2(64 bit) installed on three devices. First thing I do on opening it is to click on "about", which normally updates the browser, before I do any browsing. In the last three weeks, however, it has not updated on any of the three devices, rather, it says "Failed to check for updates". I have tried the workarounds suggested at your Help center, and nothing has worked. What gives, may I ask? Thank you

I have Windows 11 and Firefox 124.0.2. Firefox keeps asking to reinstall. I think it is because I keep getting the message that it fails to check for updates. I don't know if I have installed the Microsoft Firefox or the direct Mozilla Firefox downloaded. Maybe that is the problem, but I am not tech savvy. I have used Firefox for many years and like it. I am also too old (83) to deal with these problems. Help!

I have been using Firefox as my primary browser for a very long time. Now, every time I start Firefox, I get a message that the update failed, and that I should manually download the update file and run it. I do so, the update appears to work, and Firefox behaves, until I stop it and restart again. Then I get the same message. I looked online - it appears that others have had this problem, but no clear solution. I am not willing to use Edge, but am beginning to wonder if it is time to leave Firefox. I would appreciate a solution, preferably a reliable one. Thanks, Joe Purvis Email hidden for privacy reasons

WIndows 11 64, AMD processor, 64 GB ram. Connected via ethernet and fiber. NordVPN, and Bitdefender (neither of which has produced any error messages).

About a week ago I started getting these update error messages stating "Update available - Firefox couldn't update automatically. Download the new version". I've also tried clicking "Learn more" on the error message but it's a dead link. Going into the settings for updates I am set to auto update, but when I manually check for updates it says "Failed to check for updates".

The help article on this issue simply tells you to download and manually reinstall Firefox, but I'm having to do this nearly every day. I work in IT myself so I know a "bandaid" workaround when I see one. Is there a solution to this issue?

I have Firefox 124.0.2 running on Windows 11. For some reason, I can't update Firefox. When I manually download the update file, it appears to run Ok, but the version doesn't change. If I go to settings and click on "Check for Updates" is comes back and says Failed to Check for Updates. How do I fix this?

Originally reported on April 11th /questions/1444593: 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

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

After installing Thunderbird i had first download problems for new Firefox Versions. I tested around, installed everything new and found the solution. Somehow the Maintenance Service didn`t work properly on my machine and after deinstalling and restarting i can update firefox again. Problem remains: When trying to install Offline Languages , see picture, i get the message that it does not work. I tried everything possible, including reinstalling and deleting all old profiles (was a lot of work). Any ideas?

I want to keep browser open after closing last tab. I changed the boolean parameter "browser. tabs. closeWindowWithLastTab" to "false" but the browser still closes with closing of last tab.

What else is required ?

I can hear NO AUDIO on ANY webpage, when in Firefox. I have gone through all the suggestions on this page: [https://support.mozilla.org/en-US/kb/what-to-do-if-firefox-wont-play-any-...] but still have the problem.

I have windows 10 pro (64), 22H2 OS build 19045.4170, Windows Feature Experience Pack 1000.19054.1000.0 and latest Firefox (125.0.3) installed on A HP Pavilion Notebook 17 F121DS, Serie 5CD4355YDX. Touch Keyboard (not to be confused with on-screen) opens and closes immediately; sometimes, on the first occurrence, it stays open long enough to be able to click on a text field and then disappears. "On screen keyboard" works fine as does "Touch keyboard" in Edge and Chrome and all other Apps. Since this is a recent occurrence, and a lot of odd changes took place after the last FF update, I have reverted to Firefox 124, after this did not work also did a restore to last Restore Point from April. No change! I have consulted the [1754973] as well as [1750584] , but these did not help me much further. Any suggestions or is there a bug?

I was unable to sign in Qobuz from yesterday. I have been using Firefox ver 115 to play streaming music from Qobuz on my Windows 8.1 PC as its sound quality is better than other browsers. Yesterday, I found nothing happened after clicked the SIGN IN button on Qobuz's login page, however I had no problem using Google Chorme to login.

So I uninstalled/re-installed Firefox, and tried different older/newer versions, still didn't work.

I tried another PC running Windows 10, with Firefox ver 124.0.2, got the problem.

Please fix the problem ASAP, Firefox team. Thanks.

Its purer sound is the main reason I use firefox, instead of other browsers.

So I have an Excel workbook in my onedrive from MS, It was working fine on my firefox browser in my Ubuntu OS, last week it started to delete my cell's information whenever I pressed the enter, tab or arrow keys, I contacted the MS support and they get me to opened the same file on a chrome browser and worked fine... I still want to use my firefox browser but this problem is very annoying, please help me sort it out!!!

I heard that the newest version of Firefox (which I have not upgraded to yet) has a feature that makes it easier to accidentally visit a website whose URL is on the clipboard. I googled to find out how to disable it, and the Featured Snippet said "go to about:config and change clipboard.autocopy to false." Sounded simple, so I did it, but subsequently found out that the article it quotes from is 10 years of age!

My first question, then, is: what does changing "clipboard.autocopy" to false do if it doesn't turn off the brand-new feature?

The second question is, how do I disable the new URL Paste Suggestion feature? Will setting "clipboard.autocopy" disable it? In particular, I want to make sure that the browser does not pre-load or pre-fetch the clipboard URL, and in fact, I wish to pop up a dialog box any time I do "paste and go." People often copy URLs from e-mails to research them before visiting them directly; jumping directly will increase the likelihood of visiting an imposter site.

I'm using Firefox 124.0.2 (64 bit) on Windows, and every few days I get the error about using an older version of Firefox, with Exit or Create New Profile options. I then run "firefox -allow-downgrade" from the command prompt and everything works fine... for a few days, when it happens all over again. This only started happening a couple of weeks ago, but it's getting really annoying. How do I stop it (short of using something like Waterfox or Brave).

When I use the `--search` CLI option, Firefox searches the supplied term in a new window.

I want it to open itself in a new tab instead, so I tried out the following combination of CLI options:

``` $ firefox --new-tab --search "example" ```

Firefox does search for the given term, but it opens itself in a new window instead of a new tab, thus ignoring the `--new-tab` option.

Am I doing something wrong?

With the latest version of Firefox the menu, etc. have a font size that is TOO SMALL. There are many Mozilla posts about this problem.

My wife cannot read them. I can barely read them. If this is not fixed soon, we will switch to another browser.

Can the Firefox code writers fix this?
