Firefox Support Forum

i recently lost my computer to destruction. i have a number of files saved by Mozilla backup on a thumbdrive. i have several backup files dating from 2014 all the way until now. after re-installing Firefox on a new computer, i tried MozBackup to restore my old Firefox from the latest file dated a coupla of months ago this year. the files have names like Firefox 16.0.2 (en-US) - 2013-01-05.pcv or .pfc. when i tryt and load it into backup it saysit isn't a valid backup file. how can i get this to work?

For years I’ve had no difficulty accessing online my HSBC bank accounts in UK using Firefox. In recent days they have changed their security access method whereby their site now requests a security number generated on one’s phone using the HSBC App (it used to be a random number from an HSBC supplied handheld device) which then has to be input via my Windows 10 PC to access my data. If I use Microsoft Edge as browser, everything works fine, but when I try Firefox my system just hangs after I’ve put my bank ID into the HSBC opening page (the first security step) and simply never opens the next HSBC page which would ask me to generate the said code on my phone. Seems a browser related problem. Any ideas why Edge works but Firefox does not?

I am trying to use a new HP Spectre laptop which will be my all purpose home computer. I selected Firefox Browser as the default browser but I don't believe it has ever come up as my browser. It is loaded among many other apps (?). I used to call them programs (?). I get Edge, Chrome, Bing, and others, none of which I want or ask for. They just seem to appear randomly.

I download then open many student files each day. PDFs open fine automatically, but never Word files. In the Applications settings dialog, I have tried to choose the file format docx and doc. But neither are recognised as a valid file type. I realise that Microsoft is a bully and Mozilla may be trying to discourage its use, but I and the students are stuck with Word. How come docs and doc are invalid and how can I persuade Firefox to open them?

Thank you

I opened Firefox as usually, but passwords are missing, only logins are available. There is also a file called logins.json-1.corrupt in the profile folder.

Renaming it back to logins.json with restarting the computer does not work.

There are no previous versions of these two files available in the system.

Please let me know how I can recover passwords, may be with a special software.

Thank you!

Hi,Why is download showing up on nearly all sites I go to & HOW do I get rid of it permantently I can close it by hitting the X beside the Download,but it Should not be there Thanks Darryl

Hi, I'm having a problem with my Firefox where it doesn't let me change some of my settings. This is my home PC and I've already tried running Firefox as admin and the settings are still locked. I have reset it many times and haven't installed any extensions. I can't find anything online about this.

I am sending tabs from Firefox mobile to Firefox desktop (Arch Linux) (on a regular base for years). All worked fine. After a new install two weeks ago the Firefox desktop receives the tabs and opens them as supposed. But after a day or three when I open Firefox desktop it opens all previous tabs again together with the newly sent tabs. I deleted the Firefox profile and installed from Firefox sync but the problem occurs. I deleted all devices in sync and added my 2 devices (desktop and mobile) again but it didn't work. Does anybody have a similar problem (and a solution)?

Walmart website no longer works properly with latest Firefox 96.0.2 64-bit. It works properly with Chrome and other browsers. You can log onto the site and search for products but when you try to add a product to the cart nothing happens. You also can't actually go to the cart. Last time I used Walmart was a few weeks ago and everything worked fine!

I read that with version 100 on the Mac there will be some problems with some web pages like my bank can you tell me if this has been fixed or not, if not I don't want to go past version 99. Thanks for all help Michael Whitecotton

firefox updated itself, which normally would be fine, but now there is a PDF icon in place of my normal firefox icon, and I am afraid to use it now. Is it for real?, can I change the icon back to the old firefox one? Please let me know cause I won't use it now until I know for sure that it's ok and get it back as it was. thank you, Linda

The instructions for the Window Titler icon suggest to turn on the Title Bar (with the Firefox icon, usually shows title of active tab, but would presumably show the Window Title if one was assigned). I can't find how to turn it on in version 99.0.1. It's not where the instructions for Window Titler said to look (managing the Menu bar or the Bookmarks bar). Any suggestions?

Would love for this feature (named windows) to become a normal part of Firefox. I wouldn't mind having the Title Bar anyway; at the cost of a few pixels, I would have something to grab onto when moving windows around that wouldn't accidentally do something to a tab.

Hi,

i am having a rather weird and persistent issue. When I try to open a specific website, namely www.westend61.de, this Firefox tab crashes, as seen in the provided screenshot. With a normal website this wouldn't bother me so much, but this page is the main page of the company I work for, and therefore I and potential customers must be able to reach it. That being said, this does not necessarily have to be a Firefox problem, the issue could also be on the server side. But the website works on other computers, other operating systems and other browsers. As far as I know, the website works fine, this computer using this browser being the only exception. I worked my way through the Firefox support page:

- checked for newer firefox version - checked for newer compatible MacOS version - checked for newer graphics driver - disabled all firewall, anti virus software - started firefox in Safe Mode - reinstalled firefox & deleted all profile data - disabled hardware acceleration - set webgl.disabled to true - again safe mode

The tab crashes every time. This computer is an old End 2015 iMac running Monterey and the newest Firefox. - More information can be found in the troubleshooting information and the crash report: https://crash-stats.mozilla.org/report/index/bb11e42d-9fc9-4061-b89c-4c6400220503

Thank you very much.

Please tell me what to do to have the magazine work. It used to, but I think that some new thing like Adblock must have changed it and I cannot read the magazine now. Thanks.

I have seen this in some past versions of FF It usually goes away after a few upgrades

Instead of whatever it's supposed to display, you can see that it shows some random characters.

Annoying. I dont even remember what it's actually supposed to show

In the location bar (aka url bar aka address bar), the base domain name ("example.com") is displayed as normal text, whereas everything else in the url is displayed in gray. For example, if the displayed url is https://foo.example.com/bar, the "https://foo." and "/bar" are in gray.

Is it possible to get the whole url displayed as normal text, i.e., black, and avoid this "graying out" of some of it?

In my searches so far, I've found various other customizations for the location bar via userChrome.css, but not this one. Any help appreciated.

I'm using firefox 91.8.0esr (64-bit) as currently packaged for centos7 (x86_64), though presumably this is not system-dependent.

When viewing email on Outlook in Firefox, there now appears a rectangular black box over part of every email. This does not occur when viewing Outlook emails on Chrome or Edge. I thought it might be because of my adblocker (Ublock Origin) so I turned it off, but the black rectangle still covers part of my messages (and I have Ublock on Chrome, too, with no problem viewing Outlook).

The rectangle covers only a portion of the messages. When I scroll the message, the black rectangle remains stationary and the message scrolls behind it, thus revealing the portion previously covered by the black rectangle (a different portion of the message becomes covered).

I tried to take a screenshot to show the black rectangle covering part of the message. Amazingly, even though the black rectangle is there when I take the screenshot, the screenshot itself does not display the black rectangle....instead the message appears in the screenshot without being partially covered by the black rectangle.

Hi, I've recently noticed that Firefox is not using Intel Graphics for hardware video decoding, here are the specifics:

- I tested this on two separate PC - one laptop with dual GPU (an Intel UHD 630 and NVIDIA GTX 1070) and one desktop with dGPU removed (leaving only an Intel UHD 630 by i7-9700K), on both PC I made sure to run Firefox on Intel GPU only. - According to information I gathered online, Intel UHD 630 should support H264 decoding and VP9 decoding without any problem. - I tested videos from Youtube (VP9, non-HDR video) and Twitch (avc/h264 video) - The exact same video, when played on Microsoft Edge (Chromium), uses Intel's hardware decoder without any problem. - On the dual GPU laptop, when being forced to run on NVIDIA's GPU, Firefox correctly uses the NVDEC decoder without any problem. - Both PC uses the latest Intel driver (30.0.101.1191)

I have attached copies from about:support page below.

In Firefox settings, under General -> Performance section, I have left "Use recommended settings" checkbox on.

Could someone help?
