Firefox Support Forum

I found some infos but I do not trust myself just deleting the files in question since they ared all over my system. The following I found per malwarebytes which found the pups every day up to now:

PUP.Optional.DefaultSearch is Malwarebytes’ detection name for a family of browser hijackers targeting Chrome, Firefox and Internet Explorer. Symptoms The browsers’ default search engine was changed to one that belonged to the threat-actors. I am german so probably I need your patience in helping me to clean my system resp. Mozilla.

Looking forward Ingrid

Yesterday I went to my history to locate a prior site I had visited. There was only 1 site in history, which of course surprised me, and it was to CapitalOne.com/link accounts. This is my credit card company. I removed Firefox from my Macbook and then re-downloaded Firefox and installed. Nothing has changed. My settings are correct, meaning that I should be able to have sites visited in history, yet only the one site populates, and I've been to a lot of sites today....the credit card/link accounts site is the only site that is in history. You can imagine how nervous I am right now about doing anything on line. I sure hope that someone will help out here.

FFox 92 update today. Menu spacing went to double. No shock there. Found the CSS code below for UserChrome.css and set it up.

EX.

menupopup > menuitem, menupopup > menu {
  padding-block: 4px !important;
}
:root {
  --arrowpanel-menuitem-padding: 4px 8px !important;
}

EX:

menupopup > menuitem, menupopup > menu {
  padding-block: 0px !important;
}
:root {
  --arrowpanel-menuitem-padding: 0px 0px !important;
}

But, it doesn't get any smaller than the above 4/8px set up. Bug? Perhaps there's another CSS setting to be tweaked for V 92? I do not have any other CSS for these items elsewhere in my UserChrome file.

Each morning, when I first cold boot my computer, the moment I open my Firefox browser, I receive numerous (10+) identical error messages from Bitdefender:

Suspicious connection blocked: Feature: Online Threat Prevention

firefox.exe attempted to establish a connection relying on an unmatching security certificate to content-signature-2.cdn.mozilla.net. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one.

Question: Is this ACTUALLY coming from Firefox? If so, please match your security certificates! If that's impossible due to a technical issue, then please email me your confirmation so that I can add an exception to Bitdefender.

Question: If it's not coming from Firefox, please email me, letting me know what additional system information you require so that we can get to the bottom of who/what is masquerading as Firefox while attempting to establish an unauthorized Internet connection from my computer.

HP Envy laptop, Windows 10 OS, latest update.

This has been occurring for several months.

Thank you for your time.

This is the 3rd time I've posted here about crashing in the last month or so. I really do apologize for having to post again but I simply haven’t gotten to a solution. I really need to continue using Firefox as all the other browsers are significantly slower in my experience and I'm in the browser around-the-clock. I’d be willing to pay for customer support from Mozilla but they do not provide any type of support directly as most of you probably know.

Please review this link here to see all the steps I have already taken to troubleshoot the crashes.

I really thought that the crash reports I had would help me pinpoint the issue but it appears as though they’re not very helpful for those who can interpret them. If that’s not the case, I greatly appreciate it if anybody can dig through them to uncover some insights related to why I may be having frequent crashes (I'm willing to pay).

Thank you so much for any help.

I updated my firefox to the latest version : Version 92.0 Now in Bookmarks Toolbar (Show more bookmarks) i have a problem about double Space between bookmarks. This is really really annoying. How can i fix that double space issue?

I tried browser.proton.contextmenus.enabled > false (disables Proton UI of context menus) Did not work for me.

After last update where the bookmarks bar was is now just a message as shown below saying to place bookmarks here but won't display prior ones or let me add new ones. Also, the >> on the right side that showed a dropdown of them is gone.

My problem,using Mint20.2-MATE, with FireFox92, is that FF92 shuts down whenever I minimize FF-i.e., totally down-does NOT appear in taskbar. I know I had the same problem years ago, and it was a simple fix. However, going through the "Help" sections in FF this time was no help. thank you for any suggestions.

I know I am not the first person to complain about this. The spacing/padding between menu items, in particular the Bookmark menu is just ridiculously large. It got even bigger in 92.0!

I rely on Bookmarks heavily and use hundreds. I guess this was done for touch screens? The main interface is still currently the mouse for computers.

I see the only current fix is a using a stylesheet and it seems a bit involved. I have to give it a try. I am pleading with the designers, please give us the option to use compact padding once again. I am not sure why this is being forced on us. I really like Firefox, please don't make me look for another option. Thanks!

I browsed a clothing website for less than 5 minutes by typing in the address and not using any links. Shortly after I receive an email asking if I was still interested in what I was looking at. Does Firefox share my email address with websites I'm visiting? I believe the email is coming from SafeOpt, not the website I visited. I do have "do not track" options selected in Firefox.

In trying to fix a Mozilla VPN problem, I uninstalled and reinstalled Firefox as directed by VPN support. Now Firefox has lost its bookmarks. Can they be recovered? If so, how?

Firefox Browser uprated to 92.0 today. Previously whilst browsing Ad's were showing; today I have no Ad's displayed but have not enabled an Ad Blocker on Firefox. A site I use extensively cannot now be properly viewed; I get a message to turn off Ad Blocker. I have set Enhanced Tracking Protection to 'Off' but am still unable to obtain full functionality, I am using standard Firefox Privacy settings otherwise. I am able to browse the site properly using MS Edge. I have deliberately refrained from using any AD Blocking on my part so as to ensure the site in question can be properly viewed. The only Firefox extension being used is Kaspersky Protection; I get the turn off Ad Blocker message both when Kaspersky Protection is on or off.

When i look at a map embedded in website the cursor disappears and only shows up randomnly or when you stop moving the mouse. This makes using maps in Firefox impossible. Must be related to Firefox - works in Google Chrome Please fix or advise or I have to change webbrowser

Greetings. I have scoured the web and read all the community posts on this robot head, under remote control, and orange stripes in the address bar problem that so many people seem to be having. There are a few answers, but almost all of them use very technical terms that are way above my head and not defined. None of them provide a sequence of steps to fix the problem that a browser novice might be able to follow. Surely there must be a way to fix this or to explain to frustrated users why it is there and not removable. None of my other Firefox browsers have this on other machines.

Is there a series of steps to solve the problem? That would be so helpful especially without undefined terms. Thanks so much. This type of answer will help so many frustrated users (me included of course) :)

FF has been my default for decades primarily because of superior print options. I use Custom Print option to print out pages in larger front, but this no longer seems to work in 92.01. At say 115 custom I lose text to right and bottom of page (both in preview and print to PDF).

Hello,

I really need some help, I don't know if I can still do anything, but at least I'm asking here. Last night, my computer crashed really bad and I went to sleep, today, my Firefox tabs were all gone. I had more than 200 open tabs with stuff to keep in mind, stuff to do later and other things... The weirdest part is that I still had some tabs opened, but it was tabs from 21/012021, how bizarre is that?

I tried everything I could find on here or on other website, but nothing helped. I even tried a recovery of my computer to a week ago, in vain. The only useful thread was this one : https://support.mozilla.org/en-US/questions/1310742

With ShadowExplorer I found two files from the 23/01/2022 in sessionstore-backups : recovery.baklz4 recovery.jsonlz4

But trying the methods from the previous thread never worked. I also tried to just copy my whole profile folder from the 23/01/2022, and again, no result.

I'm stuck now, I really don't want to lose my tabs and I KNOW they're somewhere.

Thanks in advance.

Before I close the Firefox browser i go to Settings>Clear Data> Cookies & Site Data>Cached Web Content. I clear all and the Cached Web Content is lowered to 45kb. History is deleted. There is nothing in Manage Data or Manage Exceptions. The computer is turned off. A day later the computer is turned on and Cached Web Content is 2Mb.

Windows Defender anti-virus malware scan and full scan have been run. The computer is up to date, Win 10 Home, version 21H1, OS build 19043.1237.

Any idea what is causing Cached Web Content to grow from 45kb to 2 Mb when the computer is turned off?

since yr last update i have lost all my tabs, settings, and pinned tabs, what is happening can you help me stabilize this and i can not get any o\lfd them back from history as every time i open firefox, a second window opens and then keep cycling thru all the pasty websites i have visited and i cant stop it

So I've got Proton UI forced on me today in 92.0 update and accordingly had to spend my entire evening trying to repair all of the damage. So far I've managed to fix menu spacing and the way tabs look all while not breaking previous walls of text in userChrome.css meant to fix even older UI problems. Still one thing I failed to find any solutions to is the bookmark drop-down menus color issue. Those menus used to be gray, but now they are all bright white, which to me is super annoying. Any tips on how to fully recolor those?
