Firefox Support Forum

Had an update for Firefox happen last night and now the Duck Duck Go extension will not work. Just goes search not found?

Here is the error - There was an error displaying the search results. Please try again. When I turn off the extension Firefox runs fine.

I had turned off the extension first and turned back on same issue. Removed extension and reloaded same issue. Restarted router same issue. I have uninstalled Firefox and then reloaded same issue with Duck. Duck Duck Go works in my Edge browser

This is my Mac Monterey. My Windows 10 is in Safe Mode With Networking. The last update will not download. That version is 125.0.3. What's available under Windows updates does not download either. Now I am running my antivirus on my Windows to see if it runs clean. I do not know why I cannot apply these updates.

Suddenly, my login (user name & password) is not working on only one specific website, although it works perfectly with a couple other browsers. The site acts as though the information is not even being submitted-no change in site nor the "Login" button. I'm using the latest version of Firefox on Windows 10 and I have deleted all previous cookies and data, rebooted my PC with no difference in results. Thank you for any information.

Today while using firefox all my open tabs and windows crashed. Due to the situation, I had to restart my computer because everything was stuck. When it restarted I couldn't restore the previous session so I used various methods to restore it but I still can't restore the windows and tabs that were open today. I would like you to restore my session from before the failure today.

Hello! Browser version: 126 OS: Kubuntu 24.04 LTS. How to recreate: Set privacy.resistFingerprinting to true while running Kubuntu 24.04, enter a webpage like Wikipedia.

When I have privacy.resistFingerprinting set to true it breaks websites fonts (see picture). This problem occurred when I upgraded to Kubuntu 24.04 LTS.

I get the following console error that might be of interest: "Request for font "Noto Sans" blocked at visibility level 1 (requires 2)" To fix this, I tried to set the following prefs to 2 without success: user_pref("layout.css.font-visibility.private", 2); user_pref("layout.css.font-visibility.standard", 2); user_pref("layout.css.font-visibility.trackingprotection", 2);

I ran the following command, after trying to find a solution:

for i in $(echo verdana,arial,helvetica,sans-serif | tr ',' ' '); do fc-match $i; done

and I got the following results:

NotoSans-Regular.ttf: "Noto Sans" "Regular" LiberationSans-Regular.ttf: "Liberation Sans" "Regular" NimbusSans-Regular.otf: "Nimbus Sans" "Regular" NotoSans-Regular.ttf: "Noto Sans" "Regular"

Which seems normal to me.

Is there some way to fix this without having to disable privacy.resistFingerprinting?

I just accidentally deleted my account and i just can't remember my password but i don't want to reset my password because my data could be deleted and i have no backups and no other way to get my account back besides resetting my password

After updating to the current version of my OS(listed below) I can no longer drag a tab to detach it from the firefox window. Doing so drags a preview of the tab, but it is never separated from the current window. I can drag it to an already existing window to move tabs from one window to another, but not to create a new window from a single tab.

the email used for FireFox - glennww@cox.net was transferred to Yahoo. I can not seem to download emails sent to this email address into Firefox as I was able to do prior to shifting to Yahoo. I went in and changed the password to the new password and to the new POP server (pop.mail.yahoo.com) but emails can not be retrieved. What am I doing wrong. I deleted the email account glennww@cox.net and tried to re-install as a new account, but it was not accepted. I don't know where to go

Whenever I use the picture in picture feature, it always opens up in a bigger tab instead of the floating PiP. I am unable to adjust the sizing whatsoever. Is there a way to get around that?

For a very long time I have been using Afterpay successfully through Firefox. Since the last update of Firefox a few days ago, Afterpay has been failing to complete transactions. This has occurred on 3 different sites. I contacted Afterpay and it appears everything is fine on their side. This morning, after another failure, I tried the same transaction through Chrome and it was successful. Paypal still works with Firefox without a problem but it seems there is a transaction glitch between Afterpay and this updated version of Firefox.

Earlier I tried to open firefox to go on the net and Bing came up. I uninstalled Firefox and reinstalled and the same happened. Then I deleted the Firefox folder fron the hard drive and then reinstalled Firefox again. This time it opened correctly. I can only assume but don't know, the Bing thing came about through one on the windows 11 updates. How can I stop this from re-occuring or can I? I only ever use Firefox, its just the best, thank you.

PS: I did have Firefox as my default browser but Firefox still became Bing. Lis

Firefox's website appearance settings include a setting to force a light theme, force a dark theme, or to have sites automatically adapt to the theme of the browser. I feel that's not exactly what I want. I don't want the browser's theme to have anything to do with themes of the sites I'm viewing, nor to force light or dark. I think I'd rather just use the site's default, or if not that, set a theme on the site itself. Is there any way for Firefox to just not meddle in a site's theming at all?

I kinda just don't want any connection between the theme of my operating system, the theme of my browser, or either of those and the theme of websites, and none to force a theme on any of the others. I'm not sure why that seems so desirable nowadays, but I don't want it.

Trying to recover from a hard drive crash. Had to buy a new desktop with Windows 11 Pro (looking to be a bad move). I downloaded/updated to Firefox 126.0 (maybe also looking to be a bad move).

Have my last "working" userChrome file (it took me weeks to perfect this to my needs).

I am looking for: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

but there is no "AppData" folder. And there is no existing userChrome.css file, anywhere!

Is the functionality I am looking for a thing of the past?

Is Firefox not completely supported by Windows 11?

If so, what is the last version of Firefox that will still support userChrome.css?

Firefox only offers seven filetypes for handling (open or save the file). How can I enter more, for example what to do with an xlsx file? I want Excel to open the file, not download it.

whenever I am filling out an online form that requires basic info, Firefox prompts the common info that I have input in the past via the Auto-fill feature. Whenever I click on the suggested information, a new settings tab opens and switches my screen view to that tab. This didn't happen prior to the most recent update and has made filling out various forms extremely tedious and frustrating.
