I have found a few pages about address rewriting; how do I disable them all ? - searching single word into google (type "keyw" in about:config to disable it) - hiding http when not using https - trying to add "www" and ".com" around a single word when the word did not resolve

I consider most of them as security issues for various reasons.

And when editting an URL, I want firefox to keep showing the full url as it was invoqued; not add https randomly, or removing http other days. And the more I disable some, the more new ones appear.

Hi. I've noticed similar messages like this after previous Firefox upgrades, but not for the latest.

My Firefox ESR was automatically updated to 78.11 on June 1, 2021. Since then I have not been able to access Amazon Prime. The error says:

Your web browser is missing a digital rights component.

In your web browser’s address bar, type about:addons, press Enter, and then on the left, click Plugins. For the Widevine Content Decryption Module, select Always Activate, and then refresh the video’s page and try watching the video. If the video doesn’t play, go back to Plugins, click the gear icon at the top of the page, and then click Check for Updates. When the plugins have updated, refresh the video’s page, and then try watching the video.

The suggestions get me no where. It is already on "Always Activate" and newer updates are available.

I tried uninstalling and reinstalling a early version, but this does not work either. I get a message at the top saying that "Firefox is installing components needed to plate the audio or video on this page. Please try again later." "Later" is apparently never.

Has any else had this issue? Any suggestions would be appreciated.

I've been using Firefox with Virgin Media's TV Go https://virgintvgo.virginmedia.com/en.html for quite a while without a problem. After the latest update I got the message to update the browser to the latest version and restart. I've tried talking to Virgin about it but been given the runaround by them - surprise. I've tried other browsers, Safari, Chrome, but the quality of the stream is poor compared to what I was getting with Firefox. Has anyone got any ideas? Any hopes?

Thanks

For the last few updates of firefox I haven't been able to restore closed tabs with the regular keyboard shortcut (believe it was ctrl+alt+t and now ctrl+shift+t). The shortcut simply does nothing at all. It is frustrating as sometimes I close a tab by accident and then I have to go through the whole process clicking to find it instead of being able to bring it back up in half the time using the shortcut. I am on firefox 90.0.

I do not use the sync function to keep my bookmarks up to date on separate computers. I have a location on a server that I can access from any of my machines. Usually I import and export to html bookmark file.

I have organized my bookmarks into various folders. When I attempted to update one of my boxes, all the bookmarks were removed from the folders and placed in a huge list in Other Bookmarks. The folder structure did not change, but all the folders were empty.

I tried to use a json file as an alternative, but this also had the same result.

I run Debian Linux on all my machines, if that matters.

What could be the problem?

Thanks in advance.

Hello,

I've had an ongoing problem that I've been ignoring, but today it was hard to ignore. I hope someone can help me.

Some webpages load with code where the buttons should be. I've included a screen shot.

I'm running FF 78.11 on a 2011 MacBook Pro with OSX 10.12.

Steps I've taken to try and fix the problem: - emptied the cache - turned off all privacy extensions independent of one another: ADP, Privacy Badger, Ghostery, Enhanced Tracking Protection and AdGuard - restarted with adons disabled

These steps didn't work.

The pages load with no problems on Chrome and Ghostery Dawn.

What is the problem here, and what can I do to fix it?

Thanks in advance for your help.

Good day, first of all I'd like to appologize because I cant seem to find any dev/support email on the main website mozilla.org so I'd like to request that if possible. This is a long read, partially why I didnt want to discuss this here but alas I have no other choice since contanting anyone from this company was unsuccessful on my part. However, since, as I assume, the devs are hiding for reasons that should be a surprise to nobody, I'd like to point out a few problems that I have encountered with using this browser, or pretty much ANY browser in this day and age.

As you all know, browsers take up a big chunk of memory when loading multiple websites. In fact, I assume that most of you have at least 8G of RAM so you might not notice the things I will be talking about here.

The thing I'd like to talk to someone about, and I really mean someone who might be competent in solving this issue, becouse this isnt only a technical issue, but a user-ignorance-enabled-compliance issue. Recently, I have decided to secure my computer a bit more due to various cyber-threat alerts and whatnot and came across `firejail` which is a neat program to sandbox applications. I then made sure to start firefox through it. Then I went one step futher and decided that the constant swapping from having 4 tabs open and having my computer brought to a screetching halt, was enough of an issue that I finally decided to do something about it. To my surprise, firefox simply, would not start, unless, I gave it at least 2700MB of memory AND 300 (yes 300) subprocesses/forks for it to function. This problem was repated on chromium too, but I wont talk about it since this is the mozilla website. Mind you, I have an old computer with a max of 3,2G of RAM and a humble Core2Duo CPU. 99% of programs do not have any issues with my low specs, except of course, browsers in general. Now before anyone suggest I get a new computer, let me suggest something to you:

How about you learn how to fucking do your job? It isn't enough, that the wave of javascript confused web-monkeys fancy themselves as programmers of the modern age, when they need to pull megabytes upon megabytes of javascript code from 10 different sources for their hello-world grade "enterpreneur" landing pages with 10 different popups to even start considering to work on something (jQuery, React, Vue, whatever-else the f*ck you m*rons use) But we also have to deal with programs, that, for some strange reason, thing they require half, if not all the concievable resources of the machine they run on. No wonder that in todays world, people refer to these programs as malware, bloatware or spyware, depending on what the program is sending about you to servers you have no idea about, but you could get an idea if you just intercept the packets firefox is sending for example.

So, after that little went I will let you meditate on the following fact: When I run firefox with the limit of 3GB and 300 max subprocesses and open facebook, it crashes after a few minutes. LinkedIn Survives a little longer. Now that is a fact, you can test it yourself. Here is the code I use to start firefox:

firejail --rlimit-nproc=300 --nice=5 --cpu=0 --rlimit-as=3000m firefox %u

The `nice` part means to treat firefox with very low priority. This is to prevent my computer from hanging or swapping, by opening a few tabs and facebook or linkedin, and that is not a joke. I am aware that placing it so low on the prio list can cause issues but i did that after I had those issues. So no. I wont change it.

And I dont even comment on the flickering and graphical glitches that occur, simply because firefox doesnt have more than 3Gigs of address space! ITS RIDICULOUS! I wont attach any pictures as of yet, but I might in the future if you really want to see webpages just falling apart in front of you. And I mean it. ghosting characters (screen glitching/duplicating) pictures just randomly disappearing based on your mouse position (yes seriously) and then reappearing just when your cursor is in the sweet spot. Sometimes I have to scroll to find the sweet spot to see the pictures.

Now, mind you, this applies to pretty much any browser. I am just re-iterating this point because I want people who actually read this to be clear that this is more of an issue with the coding habbits people came to be accustomed to.

First question I'd like answered, besides how we got to the absolute clusterf*ck that is the modern web, how does a website, take up 3G+ of RAM? why would I need 8G of RAM just to browse the internet, when roughly 10+ years ago, I only needed 2G and that was enough to browse any website with many tabs and flash-powered videogames to run smoothly PLUS a simple 3D videogame rendering on top of that, on an intel pentium 4 or older? And 2g was considered a lot back then (maybe not exactly but you get my point). I hope I am not the only one noticing this trend. Because this is a very concerning trend. Needless to say about the countless problems people experience these days due to cyber attacks and data breaches and whatnot.

Second question is this: Is it possible, for you people at mozilla, to reduce your applications memory footprint? say, down to a few hundred. If not, I want to know why. And really explain it in detail to me, all the programming aspects of it. Because I honestly do not see any reason why a web-browser, should take up more than 1g, and that is being generous.

Third question: Will you, or anyone, ever care about fast and efficient software? You want to support people in poor countries yet you ship THIS? You want to support developing countries, when your software effectively forces them to invest in expensive machines to even browse the web? Don't kid yourselves, you arent helping anyone. If you were selling 4g i5 cpu laptops to your browser alone, I wouldnt be surprised. Because that is the absolute minimum one has to get to "check their emails" RIDICULOUS!

Fourth question: Did you ever think about how people were developing whole video-games with only a few kilobytes of ram and the games, well, worked? Your browser cant live in a low-budget environment. It wont even start. Or are we planing to send children in africa alien-ware laptops so that they can register an email address? "ooh boy it better have the newest GPU GeForce RTX 3080 TURBO X, 128Gs of RAM and i78000 with 10Thz too so that I can play me some FLASH(Unity WebGL) GAMES"

I am done with my complaint, I will be copy-pasting this to chrome developers too. I know you wont do anything about this, because if it really mattered, you would have done something about it already. And you didnt. And you wont.

Have a wonderful day.

We are receiving this message from Ebay when attempting to list a product (see below). Any suggestions how to work around it please? Thank you.


Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to scgi.ebay.co.uk because this website requires a secure connection.

What can you do about it?

scgi.ebay.co.uk has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Folks frequently bemoan that Firefox doesn't have the same Ctrl+Shift+T keyboard shortcut to Restore Previous Sessions that Chromium has (heck, I'm one of them), but I noticed that Ctrl+Shift+N will restore Previously Closed Windows. From a backend perspective, is there a functional difference between these two options? Does using the Restore Previous Sessions button in the History panel behave differently in regards to, I don't know, cookies or something? I'm a little hazy on what a "session" is and why it's important.
