I can not press the "Backspace" on YouTube using Firefox, but my keyboard works fine cause in Chrome and Edge it works perfectly, I've already refreshed the tab and still not working. Have any idea of what's going on?

Hi guys i'm new in the forum so i have no idea if anybody else allready had my problem,i've tried to fix it myself but i cant seem to get it done. Yesterday i had a problem with my OS linux,and i had to reinstall the system,while i was pretty sure i had all bookmarks saved in an external HD i went straight to a quick format and reinstall of the OS,after installed all the due system update.

The Problem:

While i was importing the bookmarks.html i stored in external HD i noticed that nothing was being added in the bookmarks of Firefox,so i tried few times just in case i was doing something wrong but still nothing was being added in the bookmarks,so i tried to import the bookmarks on Tor Browser and the same thing happened nothing was imported. So it came to my mind that the .html file could've been damaged. Now i tried many ways to open the file either in command line or text editor i even tried using libreoffice,in the case of text editor,command line such gedit,pico,nano it loaded the file but it was heavily encrypted,in the case of libreoffice shortly after i tried to open the file popped up a message telling me that the file was corrupted and libreoffice couldn't read it and stopped.

I need a solution to either fix the .html file or decrypt it so i can recover the web addresses inside and it would be very bad for me since my bookmarks.html is 3.3Mb large with ALOT of bookmarks inside.

Can anybody tell me how to?

Thank you in advance for any help or suggestion that may help me to retrieve my bookmarks. Ludo.

P.S. OS Linux BackBox 7 up to date along with it latest version of Firefox that update server provides me.

Dear Community,

I have problem with my Firefox version 86.0 (64-bit). I have Windows 10 20H2 64-bit operating system. Firefox can't load some websites. For example I can load https://allegro.pl/ but I have problem sometimes with this website: https://allegro.pl/myaccount/newpayments_incoming.php

If you go there and use F5 key on keyboard (refresh website) sometimes this can't load. On other browser I don't have this issue. This very frustrated me because I can't work. On Windows 10 1909 on older machine (another computer) I don't have this issue with my firefox (this sam 86.0 version). So this is probably problem only with Windows 10 20H2.

Steps to reproduce:

1) Open new tab and go here: https://allegro.pl/myaccount/newpayments_incoming.php 2) Log in to your account for Allegro website (without account you can't load website) 3) When website loads normally you must refresh this website (F5 key on keyboard) few times (you must be patient, sometimes this can take some time) 4) When website can't load or it's load partly you can see that this stops loading when it try connect to analytics.google.com so I think that it is very strange behavior.

On other browsers on Windows 10 20H2 version this website works without issue. Only with Firefox I have a problem. On Windows 10 1909 version on another machine I can't notice this issue. Also on Ubuntu I don't have any problems with this website with firefox.

Can you fix it? I can't work on my computer with Windows 10 20H2 system. I musted to switch to another browsers (Google Chrome, Microsoft Edge). I contacted with owner of the website but this is not the first problem with Firefox on Windows 10 20H2 so you should fix it. I remember that I had some similar problems on another websites but I don't remember what was address for these websites.

Actual results:

Sometimes I can't load this website on Windows 10 20H2 64-bit: https://allegro.pl/myaccount/newpayments_incoming.php

When website can't load or it's load in a part you can see in the bottom of the browser that this stops when it try connect to analytics.google.com so it is very strange behavior.

This can be not problem only with this website.

Expected results:

I should load this website always: https://allegro.pl/myaccount/newpayments_incoming.php

I hope that you can fix it.

The issue's been going on since yesterday, the app will freeze up like it's about to crash, but then it'll just pop back up. It does it repeatedly and nothing I've done has fixed it, from restarting my computer to closing the browser. Its only gotten worse and I haven't been able to find any relevant information on how to fix this.

Hello. If I sign out of this site, then sign back in, I am not asked to re-enter my password. I just have to select my Firefox Account name.

How can I stop this so that if I log out, next time I (or anyone who accesses my PC) try to sign into this page, I will need to supply a password?

Dear Community,

I would like to download this extension: https://addons.mozilla.org/pl/firefox/addon/adblock-plus/ I would like to know how it works. If I will install this extension my firefox will be check hashsum for the files of this extension automatically? Or maybe public key of the organization/company who created Adblock Plus extension? How it is work? Can you tell me? I hope that people from Mozilla now read this and can answer for my question. This is very important for me.

Next question is to Adblock Plus extension. I can read this information: "This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing" so my question is why Mozilla don't recommended this extension? This extension now use 6,678,297 people so this is huge count. It is possible that this extension is not safe and these people now use malicious software? Why on dedicated website for this extension I can't see company name? Why this company is not verified by Mozilla? So my sugestion for people from Mozilla is to change this and check this extension or maybe add some information on website for this extension.

So I should install this extension? My friend use this on Google Chrome and he recommended me this software but I don't know if this is exatcly the same version. Maybe Chrome has verified Adblock Plus software and this is safe but Mozilla didn't verified this and this can be dangerous software because this can be not exactly the same version?

Next question is to adblocker. Why Mozilla can't make their own software to block all annoying ads and due to fight with malware? Example Opera browser have own buil-in adblocker. Why firefox can't do this? Maybe people from Mozilla should do this? This can be helpful because if this can be happen I will be not install any 3rd party software for firefox anymore and I will be safe. Maybe I can send somehow this suggestion to people from Firefox?

I hope that you can help me.

Yours faithfully, Peter

The Pop-Up for the radio-player of my favourite radio-station is always too big. When I open it, the lower part of the Pop-Up is hidden by the taskbar. When I try to pull the upper part down, to pull the whole Pop-Up-window into the screen, the upper part suddenly jumps down. With a screen ratio bigger than 100% it can happen the whole Pop-Up disappears below the taskbar. The radio-station writes that it is a problem by Firefox. In Chrome the Pop-Up has the right size. (here the site with the problem https://www.srf.ch/radio-srf-virus/ press on "Jetzt Hören")

Windows 10 Pro 20H2, 64-Bit, Firefox 86.0 64-Bit

How can I replace the crappy Linux home page (using Mint 20.0) and replace it with the traditional Firefox homepage? Firefox and Mozilla have been no help at all, which I feel is pretty sorry support for their users. They know exactly what the problem is and why it exist.

services.sync.prefs.sync.browser.startup.homepage = true already

Please contact me at jlannex@gmail.com if you have a solution.

Hi everyone!

How can I restore a previous version of Firefox on my Galaxy J4+? I tried to follow instructions that started with "in search box type: about:preferences#advanced". That didn't work.

I also opened http://ftp.mozilla.org/pub/firefox/releases/83.0/win32/ I don't know which version I had before this one, in which the search bar is at the bottom. I just figured 83 was far back enough! But the .exe file I downloaded could no be opened by my phone.

Below is the current version: (I hate this version. So sad. Firefox was excellent. But if I can restore a previous version, that would be great.) 86.1.1 (Build #2015794881) AC: 72.0.16, f4aa67a9c GV: 86.0-20210222142601 AS: 67.2.0

Thank you for your help!!! Mabel

Hi Guys 'n Gals, As of today, I am unable to log into the Australian Tax office Business Portal or Business Services (BETA) through MyGov using Firefox browser. I can log in through Edge, no problem to both. I've cleared histories, cache etc on Firefox, and it is up to date. I've logged out, and logged back in. When I attempt to enter the email address to log on to ATO using Firefox, I can type the address as far as ".com". The moment I type ".", I lose the entire address, except for the ".". I don't get to the "com.au" part at all. I've contacted the ATO, they have no updates at all regarding issues with Firefox. We are getting close to Plan C (Sledge Hammer LOL). Any and all help gratefully accepted, I do not like edge....... Thank you Trina

I often find duplicate bookmarks in my folders and with tags. If I have two identical entries and try to delete only one of them, both bookmarks disappear. Why is that, and how do I prevent it fom happening?

I am constantly frustrated by unresponsive pages / script warnings etc using Firefox. This never used to happen on previous builds -- I am using the latest 86.0 -- but these occur so often that I am about to say goodbye to Firefox. This does not happen when I am using Chrome and other browsers.

I have been through all of the suggested steps to deal with these unresponsive script/page issues, and none has worked.

Would appreciate any help on this, but as I say I am about to leave Firefox at this point for Chrome and other browsers.

Thanks in advance...

I use a Logitech MX Master 3 mouse, without any custom Logitech or other mouse software. When I press the mouse's back/forward buttons, instead of navigating back/forward, Firefox enter Scroll Mode (more info here). This is the same behaviour as when pressing the middle mouse button. However, I already have the middle mouse button for that! I want the back/forward buttons on the mouse to navigate back/forward. See the attached image for the back and forward buttons I'm referring to: they're directly under the horizontal scroll wheel.

Is there a way for Firefox to register the back/forward button presses as back/forward navigation commands?
