Adblock Plus - is it safe? Why Mozilla doesn't recommended it? I used it in the past some years ago but now I am scary about safety

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

Dear Mozilla Community,

I would like to suggest you to make built in adblocker in Firefox. For example Opera have this feature so we don't need install any extension. People from Mozilla read subjects in support.mozilla.org? If not where I can send my suggestion?

P.S. I wanted to install Adblock Plus extension but I am afraid about safety so better option is to make built in adblocker to protect from malware. I think that this can be direction in good way.

Yours faithfully, Piotr

Hi i would like to know how i can change the font size of my Firefox Menu.

i already change the size of the layout whit "layout.css.devPixelsPerPx" but it didn´t change the font size of the tabs or the menu. i did some research and found the userCrome.css technique to change some fonts sizes. i already change the font size of the address bar, PopMenu and tabs. But when it comes to the Main Menu, and bookmarks the font still in the same size. i also try changing the fonts size on preferences but nothing has been working.

i guess there must be a simple command line to add in the userCrome.css file to fix this but i can find it.

if some of you can help me i will appreciate very much.

i am working on a linux machine. thank you very much

Hello everyone,

I'm an avid user of Firefox latest on Manjaro, up to date.

Since yesterday, when I updated from Firefox 87.0-1 to 87.0-2, I have a strange bug using DuckduckGo.

What happens ?

  • When on DuckduckGo result page, clicking a link won't open when using the "Open in another tab" setting
  • I will open the link if that setting is not used
  • I can open it in a new tab with the right-click menu, or by ctrl-clicking it.
  • When hovering above a link, the bottom-left tooltip does show up and the cursor does become a hand, suggesting the link should work. Alas, it doesn't.

What did I try ?

  • I did restart in "safe mode", with all addons disabled.
  • I did reset the cache.
  • I tried testing the same behavior on Google, and it did work as expected.
  • I tried DDG in another browser (Gnome Web/Epiphany), and it worked as expected.

I have yet to notice the same issue with any other website. Any Idea where I should report this minor, but annoying but ?

Thanks & Cheers, -- JAB

I had a system update couple of days ago and since then, the firefox browser suddenly hangs or partially blacks out in certain areas suddenly. It sometimes corrupts the text/data on the toolbars, add-ons, etc.

It happens randomly. When I restart the system it works fine and then it happens again at random instance.

Not sure what is causing this. But this only began since Thursday.

Not sure what to do.

Hi! Glad someone is here to help!

Last week I was signed out of my Hotmail account. Which is now technically Outlook, but I still have a Hotmail email address. I did not sign out. Just came home to discover that I was signed out. I found the main Outlook sign up page, which also had "sign in" on it, which I clicked.

The next thing that showed up was a mostly blank page with the Microsoft squares, my email address, and password filled in in the upper left corner of the page. Underneath it said "next" which I clicked, and nothing happened. I tried to chat with Microsoft about it, and in the end I downloaded Chrome, which instantly let me into my account. I truly don't want to use Chrome. But so far my ability to access my account via Firefox has not been successful. I would be so happy if anyone could help me understand what is gong on, and how to fix it. Thank for reading this!!!!!! ps I have Linux as my operating system. I had someone who knows Linux well come to help me, but he couldn't figure it out either.

Default theme is used.


According to https://www.reddit.com/r/firefox/comments/8k3sq4/firefox_updated_to_6001_and_the_search_box_is_no/ there's something wrong with userchrome.css in the profile but that file should be patched if that's the case.

Why this hasn't been patched since it's introduction in version 60 is beyond me.

When I type in ANY URL, I want exactly that to be loaded. And not anything else.

When I type in mozilla.rog into the address bar, I want firefox to fetch the page mozilla.rog. I want firefox to try, and if it does not exist, I demand to be notified that it does not exist. With an error message. URL not found. Error 404.

But instead, Firefox silently changes mozilla.rog to mozilla.org (and probably any page e.g. from .rog to .org, and from .ocm to .com , and the like) without my permission, and loads this other page I did not type in.

I do NOT and NEVER allow ANY program to alter my commands without notifying me.

so... which about:config setting disables this autocorrection-behavior?

My Mozilla occasionally crashes on various websites but this is rarely a big deal and is usually restored without further problem. However, when trying to access my online banking (Co-operative and Smile) it crashes repeatedly after a few seconds, making these sites unusable. Anyone got any ideas why this specific site is a problem and how to overcome it?

My cookie cache is erased every time firefox closes and I only have Ecosia as an Add on. My security setting was strict but I changed it to standard. This had no effect. I'm not very familiar with Linux so a simple explanation would be appreciated!

Thanks in advance

P.S; The crash reports fail to submit. I don't know if this is related.
