The 125.0.2 update broke Amazon Prime Video. Firefox refuses to play ANY video, causes website to return a "That shouldn't have happened" error page. Prime Video plays just fine on Safari 16.6.1, macOS 11.7.10. Amazon says just to use Safari, but I want Firefox to work right.

I recently added the "Display Autoplay" extension. I can't seem to figure out how to get the icon to show in the tool bar. See Attached acreen shot. That's assuming that this extension icon can be added to the tool bar. I look forward to anyone's comments. Thanks

After updating the Mozilla browser, two sites related to watching TV movies stopped opening - Apple TV and Canal +. The Apple TV site does not respond at all, Canal + shows an error. Clearing cookies doesn't help. Another browser, Chrome, opens pages normally.

I run Firefox on a Mac. I've saved my gmail login credentials in my Firefox saved passwords. About a month ago I started having a problem where opening the gmail login page no longer autofills my gmail username. I've used Firefox, Gmail, and Mac together for 14 years. This has never been a problem until July 2024.

I can't find an answer in Mozilla Support, Stackoverflow, etc.

Hey all,

Last night I made the mistake of clicking a sketchy link on twitter thinking what it was some meme site( the person who tweeted is someone I know personally so I thought it was safe) once I clicked on it, I wasn’t redirected to the site so I thought it was weird then once I learned that he deleted it because it was compromised. I got scared and I was running scans through Microsoft defender. After the full scan it said that it detected Trojan:HTML/Phish!pz and the affected files where C:\Users\….\Local\Mozilla\Firefox\Profiles\cq0glqqq.default-release\cache2\entries. I deleted my cache a few hours later than I should.

So I reached out to a friend and they told me that it was probably was a false flag and I didn’t need to delete my cache. But I’m nervous that it’s an actual threat and I should do more to ensure my computer is completely safe. Also probably a lot of grammar mistakes I haven’t slept since I got this information.

Hi

OK so I was having some issues with firefox where I had to reinstall it and this did in fact resolve the issues I was having.

Problem I have is this though when I reinstalled it I first backed up my chrome folder which had all my custom CSS to move the tabs to the bottom of the header area and when I then reinstalled FF I then copied the folder back into my profile folder using the More Info under the help menu to make sure I was in fact in the right profile folder.

Problem is the code isn't moving the tabs and I seem to remember some issues with this the last time we had to fix FF that something had changed with the Chrome folders and such.

So what do I need to do to get my tabs back on the bottom again as I hate them up top!

Version: 128.0.3

Thanks!

using firefox version 109 and my internet down load manager no longer works, it works in other browsers but not since updating firefox. not sure if i was successful in posting this request prior to this one so will give it another try. thanks

On certain websites I am getting scrambled text, mostly in headings and titles, not so much in body text. I have followed several tips from other posts like mine, i.e., installed Open Sans font, but that did not do it. I turned off hardware acceleration, and cleared the cache. The only thing that did work was to start Firefox in troubleshooting mode. I only have two add-ons running, Short URL and Dashlane, I doubt they're responsible for this. Any other ideas?

Hi,

This has been brought up before, but not with this exact question (not that I could find, at least).

I understand that cookies cannot be synced across devices, but this is not what I am asking for. Is there a way to make firefox sync the list of exceptions? Meaning, only the specified website URL and its status, not the cookies from these sites.

I noticed today that there's a small blue cube appears at the tip of the mousecursor inside a firefox window , I guess it's some keyboard shortcut I accidentally activated but can't find any info on where to disable

Hello,

Couple of days ago I could not start up Mozilla Firefox due to a corrupted file. Naturally, I was immediately worried about my bookmarks, extensions, browse history...

In the end I re-installed Mozilla Firefox -without removing my old folders on C-drive and in AppData- and was able to recover my old bookmarks and extensions just fine.

However, for my old browse history I am not so sure. I have not found a way to restore those.

Could someone help?

Thank you in advance!

Yesterday, I noticed after I closed and re-opened Firefox, my browsing session was completely gone - all my tabs and windows, my entire browsing history, website sign-in status, all completely gone. I've been troubleshooting since then.

I've noticed that the 'sessionstore-backups' folder in my profile folder is missing. When I open Firefox, this folder is created and Firefox writes some data to it, but Firefox seems to delete the folder as soon as I quit Firefox. Firefox should not be doing this. My Firefox is configured to open previous windows and tabs, and is NOT configured to wipe any browsing data of any kind when it closes.

As a sanity check, I spun up a Windows Sandbox (briefly, it's a clean, isolated Windows environment) and installed Firefox there. I also enabled the option 'Open previous windows and tabs'. Firefox behaves normally - it re-opens the tabs/windows I had open when I quit Firefox. Great, that's what I expect. The trouble starts as soon as I sign in to sync. After signing in to sync, and letting the initial sync process complete, I open a couple of windows and tabs, then quit Firefox. Firefox begins nuking my browsing session again - the 'sessionstore-backups' folder is erased, and next time I start Firefox, all my windows and tabs are missing, and my browsing history is missing.

So, at this point, I'm assuming something in my synced data has become corrupt. I haven't installed any new extensions lately. I haven't changed any of Firefox's settings that would cause this to happen. The only thing I have done differently lately was enable Firefox Sync in LibreWolf and sign in to sync there. It seems like this session-nuking trouble started after I signed in to sync in LibreWolf. I assumed, since LibreWolf is a fork of Firefox, and because there were no warnings or indications the feature was incomplete/unstable/experimental/etc., that it would just work, that it wouldn't cause any issues. But it seems like it has caused issues. I checked LibreWolf's issues tracker for anything related to 'sync', but I didn't see anything noteworthy.

I've been using Firefox and Sync for numerous years without issue. This session-nuking thing started yesterday.

I use Firefox in a few places, and based on what I saw happen in my Windows Sandbox, this session-nuking issue is going to happen in every Firefox I'm signed in to as soon as it has a chance to sync. Obviously, I do not want this to happen.

What can I do to determine what the issue is? What can I do to check if something in my synced data has become corrupted? What can I do to reverse it? I'm not opposed to completely wiping/resetting my synced data, but I'd rather not if I don't have to. The only thing I would lose sleep over is my bookmarks, but I know I can export them. Are there any debug logs I can enable/look at? Anything I should look for in Event Viewer?

Thanks.

Hi,

On https://replit.com/login, no captcha is visible, and login in says "Your captcha token is invalid. Please refresh the page and try again.."

I tested with LibreWolf 128.0.3-2 and FF 129.0.2.

With Chrome, it works.

I use Firefox web browser, my OS is Windows 10 pro. I am the webmaster for site http://eckankarinoklahoma.org. When I revise and update the website pages, Firefox does not recognize the changes made until I hit the reload (renewal) button to the right of the address. However, when there is no reload button for a page, Firefox never will recognize the changes that have been made until I delete my browsing history. It appears to be read web history pages. I've tried everything, from reloading the page to getting out of the site and returning, etc. to get Firefox to recognize the changes but it will not. Like I said, the only way I can get it to recognize the changes is to delete my history, which is a real pain. The page that doesn't have a reload button is a password protected page. See site mentioned above and click left hand menu item "Members Login here." However, by visiting this page you won't be able to see the problem until you have visited it, and then again after it has been revised. The only revision made to this page is the date in the label asking for the password. The password works fine, it's just that the label never updates and this is important for users to know in which article to find the password. Sorry for the wordiness of this, but I hope you get the idea of the problem.

Any advice returned by Google seems to be obsolete or only worked perhaps in older versions of Firefox. The main idea of using userChrome.css to override the default styles for Reader View does not seem to work. My userChrome.css file does work on other items though (like removing the sidebar width restriction).

Whatever advice I find via Google perhaps cites outdated CSS selectors, but current selectors do not seem to be documented anywhere by Mozilla. Moreover, I cannot find any file on my local drive named aboutReader.css when using find or grep commands in bash, those this file name is alluded to when viewing a page in Reader View and then in turn viewing source on that transformed page.

Moreover, addons that would allow me to change the colors seem to be restricted in Reader View.

It does seem like something has changed in recent Firefox updates but I can't remember when I last saw, for instance, links in dark mode Reader View that were still pink (whereas now they are blue, and impossibly dark to see, especially when you are disabling as much blue light as possible through your operating system). I need a higher contrast color for links in dark mode Reader View so I can actually see them.

I can alternatively use the Tranquility Reader addon and have custom colors, but A) that addon does not work with the Automatic Reader View addon, whereby I can always have various sites appear in some sort of "reader view" whether the native one or Tranquility Reader, and B) hitting refresh when in Reader View will defeat some soft paywalls but this does not work with, e.g., Tranquility Reader, so I still would prefer to be able to custom colors in the native Reader View feature, rather than rely on an addon.

1. Where are the current styles for Reader View even documented? 2. Is overriding them now restricted? 3. Why did the link color change from pink to blue in newer versions of Firefox (this is a terrible accessibility bug)? 4 .Where is the alluded to aboutReader.css stylesheet actually stored on my computer (it doesn't seem to be a file on the filesystem in the Firefox profiles folder, it seems more like it is embedded in the Firefox binary/executable)? 5. Will Firefox settings ever allow us to set colors specifically for Reader View (I don't mean the override settings for all web pages, particularly web pages not being rendered in Reader View ... that setting does not help in Reader View, nor would it be the desired preference for pages not in Reader View)?

Thank you.

Hello, I've been trying to use my Firefox browser for the past week and nothing I do seems to work. Whenever I click the icon on my Windows desktop, it sends me the following Mozilla Crash Report:

We're Sorry

Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts.

To help us diagnose and fix the problem, you can send us a crash report.

I've restarted my computer and tried to change multiple settings, but the same pop up message keeps appearing. I've checked the box that sends the crash to Mozilla and clicked the button that says Restart Firefox, but still nothing. There's also a "Detail" button that provides a bunch of information that I'm not sure how to interpret haha but I can try to copy that if you think it would be helpful.

I would appreciate any help. I'm looking to get a new computer (not sure if that is part of the issue), but I'm really hoping to be able to save the bookmarks I had.

Thank you.

When I'm composing a message there, and copy some text from i.e. that thread page, this thread page, a google search, etc. in the Firefox browser, and try to paste it into my message, nothing happens.

However, If I paste the item elsewhere, i.e. in my test editor, and copy it from there, then I can paste it into the answers.microsoft.com. thread message.

I initially thought this was some Microsoft site restriction, but I don't experience this in Chrome. Not only can I paste into a thread there, but I can copy something on that page and paste it into that Microsoft thread in Firefox.

So I suppose. strictly speaking, this is a pasting problem.

Here's an example of a thread there link text

Hello friends,

As the title of the subject entails, I am trying to disable Firefox's new translation tool, becasue I'm using a 3rd party extension.

I tried to follow the solution on the following support thread ( [https://support.mozilla.org/en-US/que.../1434741#question-reply] ), but it didn't work for me, and I'm still seeing the new translate button.

Is there another way to fix this?

I'm using Firefox 129.0.1 (64bit) for MacOS.

Helo team, I think I hit some key and firefox settings changed. I see squiggly characters in menu options, bookmarks etc.. Web pages load all right. I tried uninstalling/reinstalling. It did not help. Please see attached screenshots. I use a Mac M1 mini.
