Firefox Community Forum

I met the same issue with https://stackoverflow.com/questions/27514404/web-worker-blocked-by-main-thread-in-chrome . It was asked 10 years ago and I learnt that it was fixed in chrome via https://issues.chromium.org/issues/40398809 . Is it a bug for firefox? Is there any way to work around? Thanks.

Since updating Firefox I can no longer connect to known good sites without getting "Did Not Connect: Potential Security Issue".

This includes U.S. government sites! For instance, try connecting to https://covidtests.gov/ .

Why completely block access to the site? Why can't I make exceptions or tell Firefox to accept the risk and continue?

How do I turn this odd feature that dims FF bars when window loses focus? As of look of it only tabbar and toolbar are affected. I couldn't find anything relevant under "about:config". Also some tricks with CSS didn't work for me, maybe because I have custom chromeCSS that brings tabbar under bookmarksbar and applies other customization so that FF window looks like old good FF before they started to put everything on a single line in the bar. Thanks in advance.

The newest version of Firefox now has what seems to be a permanent sidebar on the left side of the screen. This is incredibly inconvenient as 1) I have no need for it or any of the AI stuff and 2) I'm using an older screen that is square and so now web pages are contorted when I view them.

Please remove this bar or let me know how to remove it myself.

Thank you.

What has happened to the "More actions" menu button - the one that normally is in the upper left corner of windows (see the attached image)?

I have just installed a new PC, with Debian 12 and KDE (plasma 5.27.5); the other windows have this menu button, but not Firefox and Thunderbird. Is there a way to get it back, eg by moving the menu bar out of the title bar and back to where it used to be?

Having updated to latest browser version I am continually getting this page

https://www.mozilla.org/en-GB/firefox/133.0/whatsnew/?oldversion=132.0

It is not in my startup URL's I use the default.

I have cleared all browser cache and data with no effect.

Firefox on my 2018 MacBook Pro started having issues downloading all file types after I disconnected Dropbox sync and backup. Each time I try to download a file, a failed message is displayed below the file name and type. The browser was using the downloads folder that was synced with Dropbox. After disconnecting Dropbox, I tried changing the downloads location, but the "Choose" button does not display a window. The result is the same whether the Always ask you where to save files is checked or not.

I have gone through the following steps trying to resolve this issue with no success.

1. I have reset/cleared any configuration setting found using about:config and browser.download.
2. I have launched Firefox in troubleshoot mode and tested downloads with no resolution.
3. I have uninstalled Firefox and installed a fresh copy from mozilla.org with no resolution.
4. I have set the downloads folder in Safari, but this did not provide a resolution. Downloads work as expected in Brave and Safari. The current downloads location is the Downloads directory on my iCloud Drive.

The second screenshot with the error attached in still referencing the Dropbox-connected Downloads folder. No other browsers are using this folder and the Dropbox app has been completely removed from my laptop.

I use Firefox for web development and need to be able to download various files throughout the day, so this has become very frustrating.

Any help is greatly appreciated.

Cheers,

im not very good with tech so ive probably clicked the wrong things, but i cant use my firefox at all anymore. only to search up 'google.com' lol. it opens on the homescreen, but when i want to search anything it always comes out on the screen in the image included. ive been using firefox for a year or so and never had issues. ive tried deleting and reinstalling, restarting my laptop, the whole deal. im on windows 10 but that shouldnt be the issue i imagine. ive asked some friends and they dont understand it either. id love to get some help otherwise i might have to go back to google chrome D:

Yesterday I attempted to set up an account on Hulu. Every time I put in a password, it was rejected. I tried multiple times thinking it was a problem with Hulu. Did not work. So I went to Chrome and was able to set up an account without password being rejected -- I wonder if there is a solution to this as I want to use FF -- thanks.

The list of previously visited sites in firefox windows seems to have shrunk in some recent update of firefox. Now, when I click the address bar I only get 5 options, the first being search with google and the remaining 4 being previously visited sites. Used to be that list was much longer. Is there a way to customize this, or revert it back to where it contains 10+ items?

Just noticed the book mark banner under the URL line. It is taking up screen space. How do I get rid of it? How did it get displayed? Did some searching but no positive results. Not sure what to search for, definitely not book mark. If I delete the items from the banner are they deleted from my list of book marks. Some of these\book marks I do not remember saving? Where did they come from, some AI search or paid for vendor adds?

I prefer the tabs be below the bookmark bar, and successfully modified the CSS file to do this some time back. Now update 133 has once again pushed them up below the menu bar. What do I have to do to get them back where I want them this time? And why can't you just leave the tab location preference alone when doing updates?

After upgrading to FIREFOX 133 everything became a mess !!

Most pages will RANDOMLY not load and show “Security Connection Failed” message, indicating mostly one of this two errors Error code: PR_END_OF_FILE_ERROR Error code: SSL_ERROR_RX_RECORD_TOO_LONG Additionally and consistently trying to access Amazon makes it think I am a Robot, and shows a page with a Captcha but the images do not load (Image attached) 1Password fails in some pages (Such as CNN), the page shows an error message when userid & password are filled in, rendering it useless. NONE of this happen on previous versions of Firefox or on EDGE with the updated Norton360

I have tried: - Uninstalling, deleting all files and re-installing both Firefox and Norton 360 - Deleting the Firefox profile and starting from zero - Using Firefox without any Extension, it works for a while but then fails (memory overlay issue ?) - Loading a few extensions, again works for a while but then fails. If more trhan 4 or 5 extensions are loaded the problem is immediate (memory overlay issue ?) - Turning off Norton sometimes helps get to a page, and when turning it back on keeps working … Sometimes it does not - - Checked all indicaytions on support article https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect without any luck WHAT TO DO ?

First of all, why are there two Other Bookmarks folders? When I add a new bookmark, my routine is to open Manage Bookmarks, drag the new bookmark to the second (lower) Other bookmarks folder, then choose Sort > Sort by Name. I have also tried A > Z Sort Order. The sorts work within the Manage Bookmarks window, but they are not saved automatically, and I do not see a way to save them manually. Also, if I go to the Other Bookmarks folder on the far right side of the Bookmarks Toolbar, I have to scroll down to the bottom of the list to see my new bookmarks. They are not in ascending alphabetical order the way I want them.

Malwarebytes keeps blocking Mozilla files that seem to originate from it's folder in my laptop as riskware. Is this something I should make exceptions for? Or is it riskware. I'm running Win 11

Hi,

I cannot seem to close a tab, usually the last one I opened, in my browser window. It remains at the upper left hand corner of the browser. Please note the tab in the attached image.

How do I close this window and prevent this behavior again?

Many thanks,

Why does hitting my Home button open another tab? It's irritating and unnecessary. How do I make it stop?

For that matter, Why can't I open a new tab with my home page already open? I want Duckduckgo. You are bullying me into a blank page or a Firefox page. I used to have a choice.

Anybody. I'm ending up with dozens of tabs open because: 1. every time I hit HOME on my work tab, a new tab open up. One after another. It doesn't take long to have dozens of tabs open. Can anybody help me out here?

Hello

I use Firefox 132.0.1 under Fedora 14 Linux. Whenever I click an urls in another application (e.g. Libreoffice, Keepass...) a new tab is opened in Firefox (according to Firefox's settings), but Firefox itself does not pop up in the foreground, it remains in the background. I highly appreciate the setting 'open links in tabs instead of new windows'. But FF only comes to foreground in case I deactivate 'open links in tabs instead of new windows'. How can I prevent FF to stay in the background in case 'open links in tabs instead of new windows' is enabled?

Thank you in advance

Does anyone know where Mozilla wallpapers are stored? I wanted to set a wallpaper from Mozilla's menu as the desktop wallpaper on my laptop. I looked for hidden files and checked the forums, but I can't find them in the given locations e.g. my profile. Maybe these files are masked somehow. I'm looking for particular wallpaper from the abstraction category (screenshot). Can anyone tell me how to find it?
