Firefox Support Forum

Just now, after a massive and catastrophic SUPER-MELTDOWN-crash that arbitrarily decided to absolutely murder my day, ALL my tabs and windows and ALL history of "Recently Closed" tabs and windows is gone!

THIS IS COMPLETELY UNACCEPTABLE!

What is the reason for the existence of a SYNC feature if it isn't to MAKE SURE that a record of open tabs and windows is SECURELY maintained no matter how many times the application crashes, so that AT ALL TIMES, this information is kept INTACT, regardless of the state of the end users device? That is BY FAR the most important part of the sync feature! Are you telling me that there is no backup process of that information?

This is the kind of thing I never expected from you guys at Mozilla. I've been using Firefox for MANY years because I trust what you do. Today that trust has been SEVERELY and BRUTALLY wounded, most likely beyond repair...

I need you to fix this...

I need you to recover that information for me and I need you to make sure that what just happened could never, ever happen again unless God himself caused every digital storage unit on earth to disintegrate.

Since 88.0.1 all Amazon Prime Video content displays this message: "Your browser does not support High-Definition playback due to content restrictions. Please update your browser for the best Prime Video experience".

I've tried turning off vpn, adblocker, and set tracking protection back to 'standard', nothing helps.

I'm on W10 1909 Home which is technically not supported by MS as from this week so I did consider that as a possible (but unlikely) reason for it. However, the content plays fine in MS Edge. The content also plays fine from a laptop running Chrome on 1909 Enterprise (similar build to mine albeit not out of support yet).

I see widevine was updated in 88.0.1 - could this be the issue?

Thanks

I'm on Ubuntu 22.04 which is using the snap package of Firefox.

It seems that I cannot open local files in the /tmp directory. When I place a test.html file there and run `firefox /tmp/test.html`, it returns a file not found error. Why?

I don't have the problem with files in my home directory.

Firefox 87.0 / MacOS, in safe mode, with and without enhanced protection. Mostly after clearing cache. Server is Apache, running WordPress.

Other browsers (Chrome, Opera, IE) have no problems.

Using HTTPS.

Page itself (HTML) loads correctly. The referenced (linked) files do not load, even though they are on the same server.

When I look at the Network Analysis tab, I see that the CSS and JSS files have no return codes, and show 0 Bytes transferred. It does not show the data coming from the cache. A detailed look at the request looks normal, the answer is not available. When I resend the request I get an answer, no problem.

No messages in the console.

It seems to have something to do with the server, when I deactivate certain WP plugins, the problem disappears. Perhaps the problem is worse when the server is slow... cannot prove this.

I am looking for what I can do on the Apache side to fix the problem.

Thanks in advance, Ron

I'm having a number of issues with my Firefox out of nowhere.

1. My mouse will no longer scroll, nor will my keyboard arrows. I must use my touchscreen. 2. I have "new tabs" instead of "new windows" selected, yet if I click anything, it goes to a new window. 3. I cannot close tabs without right clicking. 4. I cannot SWITCH tabs at all. 5. I cannot close Firefox without going to my start bar and right clicking. 6. Firefox seems to be aware something is wrong, opens up in a troubleshooting mode... and then doesn't troubleshoot.

(It is entirely possibly my infant slammed on the keyboard and changed a setting I can't find.)

Hi there,

We use GMail/ Calendar/ Drive for our business. On the official account, I am seeing a continuous - multi-day - situation where my Google Drive won't load when I point my browser to it unless I do at least one refresh after getting to Drive and waiting for my list of folders and documents to show up.

In the mean time, the following error shows upon on the bottom left of my screen - "The server encountered an error. Please try again later." - this has persisted for over 2 weeks when I restarted using Fiefox earlier this month. I do not get this error when using Chrome or Safari.

Today, I am also not able to see the user who last modified a document or a folder last, as you can see in the image below.

Please tell me what I can do to fix this issue.

Thanks, Mahesh

I got a new computer recently and it was already upgraded to windows 11. I downloaded Firefox because it is my main go-to. It worked for a few days then all the sudden, it just stopped loading, if I tried to search something it would just load forever and never show up. Even dev tools would not display, it just was like in a frozen state, I tried downloading the Developer version of the browser, nope! Deleting all program files, Nope! Then when I tried to use edge, smooth as can be. What the heck is going on here?

Hello, I am using a personal PC. So I don't require the Firefox to be managed by an organization. In settings it shows "Your browser is being managed by your organization" . On clicking on it, it says "The Enterprise Policies service is active but there are no policies enabled". I have attached screenshots for the same. Does any one know how to resolve this bug?

The latest example is the button to sign into LinkedIn. It is not working in Firefox, but it does in other browsers. I have other examples just from today. I have used firefox as default for many years. I assume this is a security thing, but these are basic links. I have no add-ons or other complications. Most times, I do not even realize there is a problem, but when I feel something is wrong, I try another browser and it works. Thank you.

Hi,

I have scoured the web and can't seem to find a solution to this. Either firefox doesn't support this feature or I haven't looked enough.

How can you identify the pid of a tab in firefox? There isn't a tab in the task manager that shows this, like with chrome, opera, and edge.

I'd appreciate any help.

Thanks

I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

I've been using my banking site for many years on my desktop computer. Today the site comes up but when I try to log in I get a "404" error message. I tried logging in with Edge and there was no problem. I have deleted all my banking cookies on Mozilla and the result is the same. This is a major problem and I would appreciate any suggestions.

I'm finding that Twitter is not loading in my desktop Firefox browser (89.0.1), and I'm getting the error "failedScript=polyfills". I do use an ad blocker, but it's turned off for Twitter, so I'm not sure how that could be the issue. I'm not having the same issue in Safari. Thanks for any help!

Hello, It has been more than 2-weeks since Firefox cannot access www.google.com issuing the error page : "Did Not Connect: Potential Security Issue", and the following advanced data :

Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for www.google.com. The certificate is only valid for the following names: www.google.com.eg, *.google.com.eg, google.com.eg

Opening firefox is just a blank white screen without borders (screenshot 1) Apparently it seems it didn't hang and it I can determine the location of the URL bar by hover the mouse and can click the location of the close button to close the window This is different from most issues since they can open it in Safe mode I can't even open in safe mode since it also shows a blank white screen (screenshot 2) I already tried uninstall and reinstalling with fresh settings but nothing works

When I now open my firefox browser it will only open in a minimized window located in the upper left corner of my monitor. I then need to click the "minimize window to change to "maximize" and then click it to open the window to a full size screen. As I open new tabs after this they open in full size screen mode. But once I close the browser I have to start all over again. Is this happening because of the new update? Would appreciate your help please. Note: I did not take a full pic of my desktop, just the top portion that includes what I see when I open the browser.

The BBC website believes I am in another country, other than the UK. It currently redirects from bbc.co.uk to bbc.com, with some content no longer being available.

I have checked my IP, and it is currently a UK-based IP address. I do not have any active VPN profiles.

I have refreshed Firefox, deleted profiles, and redownloded but still the issue presists.

This problem is not reflective on any other browsers on the same machine.

Grateful for your help.

This is the BBC's advice, which I have followed - https://www.bbc.co.uk/contact/questions/behind-the-scenes/website-domain-change
