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

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)?

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.

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.

I am having a weird issue in Firefox. This issue happens on all websites, in all text entry fields of any kind.

It is like there is another 'ghost box' overlapping each entry field. It is hard to tell in the pics (was hoping I could post a video), but in the first one you can see the cursor is slightly lower than the actual field. If I type, nothing will appear. Then if I click again, a bit higher, I can type into the actual field.

I have never seen this before but it happens on ALL websites. It is a bit frustrating having to re-click all the time. Also, I was getting concerned there might be some keylogger or weird virus on my machine. Any ideas what is wrong here?

I work on kubuntu 20.04 with plasma 5.18.8 desktop environment. I have a QtCurve-based custom application style, which I almost match with css for GTK apps. Firefox has to be an exception by itself! Not only that, but it changes my ability to customize its interface, from time to time and even changes access to such ability, on some updates.

My scrollbar customizations in userChrome.css and userContent.css do not work any more (other CSS changes still work, for menu/addressbar/tabbar/bookmarksbar orderint and tab styling). I had to resort to settings in user.js file, to get a 20px width scrollbar, suitable for my big screen, but... it gets very wide when I increase the focus, on some webpages and becomes very ugly! Furthermore, I cannot make sense of the proper use of "ui.themedScrollbar*" settings and the scrollbar and its slider result in the same color. These are my settings in user.js:

user_pref("widget.content.gtk-theme-override", "backwater"); user_pref("widget.non-native-theme.enabled", false); // Use GTK-3.0 gtk.css: set to false user_pref("toolkit.legacyUserProfileCustomizations.stylesheets", true); // Use userChrome.css & userContent.css: set to true user_pref("widget.gtk.alt-theme.scrollbar_active", true); user_pref("widget.non-native-theme.scrollbar.size.override", 20); // If nothing else works, fix scrollbar width to 20px user_pref("widget.non-native-theme.gtk.scrollbar.round-thumb", false); user_pref("widget.non-native-theme.gtk.scrollbar.thumb-size", 1.0); // originally 0.75 user_pref("widget.non-native-theme.gtk.scrollbar.allow-buttons", true); // it was true, anyway... user_pref("layout.css.cached-scrollbar-styles.enabled", false); user_pref("layout.css.color-mix.enabled", true); user_pref("widget.non-native-theme.scrollbar.style", 4); // wide scrollbar theme: set to 4 user_pref("ui.themedScrollbar", "#bad1f5"); user_pref("ui.themedScrollbarInactive", "#668cc4"); user_pref("ui.themedScrollbarThumb", "#e4e4e4"); user_pref("ui.themedScrollbarThumbHover", "#e4e4e4"); user_pref("ui.themedScrollbarThumbActive", "#668cc4"); user_pref("ui.themedScrollbarThumbInactive", "#bad1f5"); user_pref("browser.dom.window.dump.enabled", false); user_pref("extensions.ui.sitepermission.hidden", false); user_pref("fission.experiment.max-origins.qualified", true);

Either with the "ui.themedScrollbar*" settings or without them (and cleared from the prefs.js file), the scrollbar and its slider result in the same color, unless I (tryingly) click on some place on the scrollbar outside its slider; then I can see the slider, _only_ for the duration of the mouse-down event (which causes up or down page-hight scrolling).

The default, very thin scrollbar, as well as my modified wide scrollbar with invisible slider are both useless to me! I have even tried fx-autoconfig (https://github.com/MrOtherGuy/fx-autoconfig) to make the scrollbar CSS work, but no result. At this point, I am considering switching to another browser, despite the trust I have to mozilla, for my data and privacy.

Many of my bookmarks are corrupted. They point to other websites, not the bookmarked one. Has anyone else had this problem? Is there a fix? Thanks for any info/advice. George

I'm using Ubuntu 18.04. Developer tools kept popping up so I went into about:config & set everything to false. Now an equally annoying tab keeps opening up asking to enable them. I don't just get this hitting F12. Just like before I disabled, this keeps popping up for seemingly no reason. Guess I'm accidentally doing something with the mouse. I don't have a clue how to use developer tools. Wish I could just wipe it out completely.

Each time Firefox updates, the email client changes to the outlook default. The last 2-3 updates, mailto does not appear on the file,settings,applications menu. Nor will it populate if I type it in. I have tried every instruction to no avail. I am a long-time firefox user, non-techie and it is discouraging when things disappear with each update lately. Would appreciate any suggestions. Thanks

Hi,

In the parameters, I chose to let Firefox ask me every time what to do with PDF files. But, when the window pop up and I click "Open with ... Firefox", the browser download and open with Firefox the PDF instead of only showing it in Firefox. When I set the "Open with firefox" by default in the parameters, Firefox will this time directly open the PDF in the browser instead of downloading it.

Are you aware of this bug ? Is there a solution ?

Thank you very much !

On my old (Intel based) MacPro Zoho email works fine. On my new M1 chip MacPro when I first open Zoho, or open an email, the page does not render properly at first (buttons/links don't work etc). After a delay it refreshes and shows properly. The delay depends on how fast my internet is - in the evening it can be a minute or so. Even when the internet is good I still get 2 versions of a page with a pause in between.

I tried on Safari and it works fine - which makes me think this is a Firefox issue.

I have some screen shots but when I click the browse button below I can select a file then it just endlessly shows working. I will have to email these to you separately

Thanks Phil.
