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?

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

Recently Firefox always has the error "failed to check for update". I have tried restarting my pc and running as admin. I am on windows 10.

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

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.

After doing some reading online, I turned off hardware acceleration which turned the pink flicker black and now effects several sections of the web browser.

I view a lot of pdf documents via firefox, the light gray background makes my eyes and head hurt after prolonged usage. In the past I found a solution on this forum that advised to set pdfjs.viewerCssTheme to "2" in about:config. This set the background of pdf viewer to black/dark gray. This has worked for years until recently when the pdf viewer switched to light mode again (pic 1). I checked the about:config settings for pdfjs.viewerCssTheme but there appears to be no change. I tried restarting the browser, setting the theme to 0 and to 2 again, updating browser. Sadly the theme is still light gray. Is there a way to change it again? The desired outcome is in pic 2. I do NOT want to change the color of the pdf pages themselves.

Just updated a friend's computer from Windows 7 to 10. Installed firefox over previous ESR and now there's no way to remove the search bar from the new tab page. On my W10 system, the search bar isn't there, not sure how or why, but on her's there's no option NOT to show it as there used to be.

I found some VERY old (2014) info on this but doesn't seem to be up to date.

PLEASE give us our options back and stop taking them away, sheesh, getting as bad as Microsoft.

Is there a workaround for this to remove the redundant search bar from the new tab page since you can search from the address bar?

Thanks!

I cannot remove "Your browser is being managed by your organisation" and seems to be stopping the home settings saving. They simply revert back to the default (see image) when I restart Firefox. Not sure what is meant by "your organisation" as I am a personal user, not organisation. I'm the single user of the browser (e.g. just one user on my PC, which is me) and also Admisitrator. Can someone help me remove this. Thanks John

I accidentally pressed a lot of keys on my keyboard and for some reason the default colors of Firefox have changed. I found out that by using Ctrl+Alt+D that I can switch the colors back to normal or to the colors that now appear automatically, but this only works for one tab. If I open a new tab, it shows the weird colors (see images below). I tried looking up specific shortcuts for Firefox considering the shortcut mentioned before (Ctrl+Alt+D) only works on Firefox. But I can't find any shortcut tied to that combination. I'm unsure what to do and how to fix this.

I would appreciate it if someone could tell me how to fix this.

I just got a new computer and had my info transferred. It is probably the latest version of Firefox on the new computer now. On the previous version it seems like Favorites was spelled out toward the top of the page on the left hand side. I see now it is just a star icon. Is there any way to get it the way it used to be? I'm sure I will get used to it the new way, but I still liked it the other way. Thanks
