Firefox Community Forum

This morning I was able to access the website of: https://www.alexander-wallasch.de/ Now, ONE HOUR later I no longer can. You are doing this not for the first time, it happens regularly with websites that do not conform to what you would consider Mainstream! THis is not the sites fault. YOU ARE CENSORING ON PURPOSE: IF YOU WOULD NOT; YOU COULD SIMPLY ADD A BUTTON for every site THAT ALLOWS USERS TO OVERRIDE YOUR OPINIONS: WHY IS THAT NOT HAPPENBING? Why can the user not override your decision? Has anyone ever asked you for "help" like that?

Why the h377 did firefox change the screen shot tool by removing it from the address bar AND delete the center search bar, along with changing the location of all my recent web visit from the along the bottom of the screen? This is annoying and unhelpful to pc users, I need these functions back like they were in order to us your site on my pc. I donot and will never use firefox on my phone. If these functions are gone, then I will have leave as well. Either that or remove the update from my pc and cease ALL further updates.

I couldn't see password management page. To be specific, I click the "password" option in the top right corner lists. Normally it will show all the website that firefox saved, but now I couldn't see anything except frame. I will upload the interfance that I see. this problem happend since an update. And problem contines after several patches. The firefox version that I use is "153.0.3(64-bit)" please help!

when i go to my website on firefox it says "Secure Connection Failed" but it loads fine on safari. i've never seen it do this before. Is this a firefox issue?

full error message: Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Error Code: PR_CONNECT_RESET_ERROR

how do i fix this?

I use a paid for subscription to Gemini AI. It often creates "visuals" for me apparently using JSON code. These do not show up at all. Moreover, the buttoms and other UI controls do not display well in Firefox. Is there a way to fix this?

It is as if Firefox has disappeared from my desktop. I click on the shortcut but nothing happens. It was working fine last night. I have tried uninstalling/reinstalling but still nothing. A window does not even appear.

Moderator note: This question has need edited to add the OS info provided by the OP.

Background: On August 6th morning EST after the August 5 2026 update, attempting to use firefox lead to the window with the "end process" button so I had to close the browser multiple times and then the next time I opened firefox, the bookmarks and history were wiped. I was able to restore using a backup saved on the computer and continue as normal (aside from losing some Cookie Clicker progress, reinstalling Tampermonkey userscripts, and redoing browser extension settings) but now there's an issue with trying to backup firefox data.

Issue: Trying to back up my firefox data leads to a "There was a problem backing up. Try again in a few minutes."

When going to about:config and typing browser.backup.backup-debug-info, I get {"lastBackupAttempt":1786243812,"errorCode":9,"lastRunStep":13}

When looking at Broswer Console, there is an entry saying BackupService: Could not create C:\Users\USERNAME\Documents\Restore Firefox\desktop.ini: NotAllowedError: Could not write to `C:\Users\USERNAME\Documents\Restore Firefox\desktop.ini': failed to open file for writing (NS_ERROR_FILE_ACCESS_DENIED) BackupService.sys.mjs:4116:23 but I don't know how to address that.

Good Day.

I have encountered a problem recently with on particular forum site.

When I attempt to login I receive an error after pressing the submit button. 

The form displays this error "The submitted form was invalid. Try submitting again."

I have been using the site regulary for several years and have never had this problem

The following is what I am using:

    Firefox ver 153.0.1 64 bit
    Windows 10 and/or Windows 10 (yes this is happening on all 3 of my PCs)

The forum site is using phpBB Forum Software. I do not know the version. As stated above they have been using this software for several years.

In trouble shooting this issue I have discovered that if I do the following in the specified order I can login and create and respond to posts and Private Messages. But as soon as I log out I receive the invalid form message until I do the following steps again.

            1) Clear all cookies, temporary cache, site settings, browsing and download history, site settings
               and saved form info.
            2) Shutdown Firefox 
            3) Navigate to my profile with Windows Explorer 
            4) Delete the file cookies.sqlite

I must do this each and every time I access the site.

I am at a loss as to what to do about this. Does Firefox have any error logs or console logs? If so how can I enable them to see if I can get a better idea of what is happening?

Thanks in advance for any help with this.

Hello, I've been using Firefox for years, but last couple months or so - it's been losing Internet connection - I have to stop and restart it and all ok - somtimes for 5 mins - sometimes for 15 or so - but it's doing my head in :) Any help appreciated - Thanks

I'm using Firefox in Windows. I lost all of my bookmarks... never mind how, I think I can prevent it from happening again... and I'm trying to figure out whether there is a way to recover them.

Looking in the profile folder, I see three profiles. One is listed on the about:profiles page, and is identified as the default. The other two aren't listed there at all.

I need to select each of those other two and see whether my bookmarks can be recovered from them. But how. The about:profiles page has a button for creating a new profile, but not for adding an existing profile to the page. Either it's listed there or it's not.

It seems to me that I could create a new profile and make it the default folder, then quit Firefox and replace it with a copy of one of the profiles I want to investigate. However, I lost my bookmarks by doing something similar to that, so I'm wary of doing it again.

Can someone explain what is happening here--why there are three profiles in the default profile's folder but only one list listed, and why there's apparently no provision for making Firefox list the others?

This is not so much as a help request as a suggestion, if someone can forward this along....

I depend on containers since they were introduced. I see now that they can vanish and are not synced nor can they be easily backed up. I have lost customer accounts now because of my dependence on containers. Had I known they could vanish, I would have continued using different profiles.

Please add a warning for those who depend on containers so that they do not end up in my predicament or remove them entirely or at least do not add them by default.

My Firefox sync stopped working after the latest update. Bookmarks are not syncing between my desktop and laptop. I have tried signing out and back in but it still does not work. Any suggestions?

Not 100% sure if the topic is the right one, but here we go - I use a Macbook with Firefox 153.0.3, UK Keyboard (QWERTY) It's about the command + ` (the key in the left upper corner below the esc key, I made the ` bold so it's easier to see)

Sometimes, but only sometimes, the keyboard shortcut command + ` to cycle through open windows in Firefox does not work.

For example, I have two windows open (W1 and W2). If I'm in W1 I can use the command and it will cycle to W2. But using the same shortcut, I can't navigate back to W1. But if I use command+ SHIFT+ ` it works. This changes from day to day, sometimes it's command +` and sometimes it's command+ shift+`

This only affects Firefox, in all other programmes, the shortcut works as it should Can't find rhyme or reason- does anyone have an idea?

Hello, i recently upgraded from a 4k monitor to a dual 4k ultrawide monitor, and have been having visual issues specifically on firefox and no other applications. when firefox is out of focus and i have a different window selected, the text in the firefox window becomes blurry

Hi, I'm having trouble accessing only certain sites via Firefox. I have already cleared my cache/cookies, etc. Firefox is up to date. Proxy settings are set to "Use system proxy settings."

Following links from other sites sometimes (but not always) works, but typing in a URL or search term to the address bar results in an "Unable to connect" notice.

Examples of sites: Working: google.com instagram.com mozilla.org (main site works fine, support.mozilla.org loads only as an unformatted list of links) netflix.com

Not working: usps.com goodreads.com storygraph.com firefox.com duckduckgo.com oregonwalks.org ucla.edu

Thanks for your help!

I can't download some pdfs, notably my bank statements. I CAN download some pdfs. Eg, I can download my car manual (although it's a process of downloading it to my Google Drive). However, trying to download my bank statements, Firefox gives me no options at all, and, indeed, I get an error message. Yet I CAN download my bank statements using Google Chrome! I've carefully checked all my Firefox settings, but nothing seems to address this problem. I've spoken to my bank, and they don't know why I can't download them either. When I try to download the statements, I get a screen saying it can't give me a 'Preview' (see attached screenshot), but there's a 'Download button. When I click that I get a white screen with the 'error' message:

"No API key found in request. request_id: d52e0732a3d10a75b1ec58534845c15c"

(2nd attached screenshot.)

I have asked about this before on this forum, but to no avail.

Hi 🙂 This is a follow-up to https://support.mozilla.org/en-US/questions/1511440.

The problem is this: support.mozilla.org is a site intended for asking support questions, and it is very inconvenient not to be able to use extensions that assist with typing (notably Unicodify and Clippings).

i have 2 suggestions to do:

1) Let the user choose whether to keep extensions enabled (in which case support.mozilla.org is not privileged, the user cannot send "Troubleshooting Information", and there is no security vulnerability), or to send "Troubleshooting Information" (in which case extensions are disabled).

2) Review the design of support.mozilla.org in a way that a subdomain like ffinfos.support.mozilla.org is privileged instead of support.mozilla.org, Firefox sends "Troubleshooting Information" to ffinfos.support.mozilla.org, and extensions are enabled on support.mozilla.org but can never interact with data that Firefox would send to ffinfos.support.mozilla.org.

What do you think about this?
