Hi, I am designing a website for viewing photos like pay per view system. When an user push the shortcut CTRL+S, is there a fonctionnality to disable the media storage by permissions for example? I have tried to disable indirectly with keypress event listener but it seems there is a browser privilege for his shortcuts. More, what are the fonctionnalities you provide to help webdesigners to secure their websites? I understand and I agree about the work you make for users against tracking and for confidentiallity on the web. Regards, Thierry Lacouloumere

Hi, I have just created a keyboard for Firefox, the Bislama Dictionary for Firefox. I was wondering if someone could add it to the list of dictionaries. The local name for Bislama is just Bislama. Thanks.

Hi,

Are there any limits (count, area, size, weight) for displaying images on a webpage?

I'm working on a website that should display a large amount of images on one of its pages, however FF displays only part of them. When I downsize their dimensions more of them are displayed, when I use their lower resolution (lighter in weight) versions, more of them are displayed.

I remember, I read somewhere a few years ago that there is a limit for weight of images on a single page, which could be observed for example on a carousel with large amount of slides.

This issue doesn't seem to affect other browsers.

Unfortunately I can't find this nor any other article / post that specifies what are those limits.

Thanks, Z

Hi,

I am having an issue with a website I am developing, which I am only seeing in Firefox. To reproduce please try the following:

1. Go to https://mymummyteacher.com/store and add a product to the cart. 2. Close the tab / browser 3. Go back to https://mymummyteacher.com/store and add a product to the cart. The single product that has been just added is shown, however the Subtotal and Total are showing as if the previously added product is still in there too.

If I do a hard reload (hold down shift), all the other products then appear. So I think this is an issue with caching. I am not seeing it on other browsers. Is this a bug, or is there something I can do to stop it happening?

Thanks

Hi - I have an affiliate marketing business which uses deeplinks to take my visitors to specific product pages on third party websites. These work fine in Google Chrome but on Firefox the deeplink goes to the website homepage only. Does anyone know what I can do about this? thanks Gina

I am having an issue every 5 minutes where firefox will not load any pages it essential makes me stuck on the page. I have to than clear my cache for it to work again only to have the issue again a couple of minutes later. I have refreshed firefox 4 different times, uninstalled 3 times to no but nothing seems to work.

Tenho uma rede com mais de 500 computadores, publico documentos em pdf com bloqueamento de impressão na intranet, o firefox tem o plugin de pdf nativo e esse plugin quebra a segurança configurada do pdf, que no caso foi bloqueada a impressão e no firefox qualquer usuário consegue imprimir. Gostaria de saber como faço para desabilitar o plugin nativo pdf do firefox para todos os usuarios e que não consigam mais ter acesso em mudar a configuração, igual como fazemos com as configurações de proxy, onde fica desabilidado para o usuário a alteração

I use Firefox 97 on a Windows 10 desktop. One of the things I do with it is edit the modules on displayed web pages of a Joomla 3.10.5 site, which I manage. When I try to highlight something - to copy, or cut, or delete - the highlighting is so hard to see that I can't always tell what I've selected. It seems to be a very faint gray. This is especially annoying when I'm trying to edit the code in a module. How can I control how highlighted text is displayed?

Just to encourage you, I've tried the identical edits on my laptop, where I run Microsoft Edge, and the highlighting is perfectly clear. I'd rather stick with Firefox, but if I can't modify the highlighting, I'm going to migrate to Edge.

Hi,

We are working on an Open Source Chrome extension: Digital Assistant Client

I am recording the domnode by converting into json by domJson and saving into server. We can find the same recordednode by comparing the json attributes and matching to the original node on the page. We have one problem here when we search for the nodes sometimes we get similar nodes via json which has same property names. In that case we are trying to match the node position that we have recorded. When we try to match the node position in different screen resolutions, it gives us the wrong node. How do we solve this. My code is as given below

// calculate distance between selected node and matching node getDistance: function (node1, node2) {

  const x = node1.x - node2.x;
  const y = node1.y - node2.y;
  const dist = Math.abs(Math.sqrt(Math.pow(x, 2) + Math.pow(y, 2)));
  return dist;

},

As a developer, I am trying to disable the Password Manager feature in my webapplication across browsers. When I typed some value in input type password mentioned mdn docs and navigsted away it doesnot trigger Save Password. But it is triggering anywhere else like online ide's and all.

I would like to know how it is disabled in MDN docs.

Hello, I'm using Firefox to manage my website but when I open my blog in Firefox my site's layout is not showing like the original one with header menu but showing mobile toggle menu on Desktop, in Chrome it's showing with header menu, I don't know what's the reason behind it, my users also complained about that, can someone open my site in Mozilla to confirm if they are also experiencing it or only me? Screenshot of Mozilla and Chrome is also attached below. Thanks! Here is my blog: https://writions.com/

I need a way to install firefox from command prompt entirely automatically, so that i can include it in a batch script i'm making. I've googled around, but all the tutorials are either for Linux or require you to download the file with another browser.

FF auto-updated to 89.0.1, now a site won't work, would like to RESTORE deleted/cleared COOKIES (?!?!) for that site to see if it will help cuz deleted the cookie for it made things worse! Doesn't work under Private FF session either!!

Specifics: I am the Webmaster of (we use WIX to create/manage it) 12cdrc.org and it is working fine using Edge, Chrome, Brave, but no longer works correctly (since 89.0.1, I think happened late last night early this morning on my system) update. Most of the page loads, but the Calendar and display tweets sub-windows will not load! It will be obvious to all where they should be displaying but are not!

So, I tried removing 12cdrc.org cookies. Things got worse! Now the Login won't work either, where I was logged in as my user for the site prior to that.

I tried a Private window/session, and the Login function does work, the Calendar does show, but the tweets sub-section/window still does not display/function.

Background: This is not the first website to malfunction using Firefox... Previous version updates broke the rescuemichigan.com website (none of the pull-down menu functions work, but work fine on/with Brave, Chrome, Edge)! Also mewe.com acts up using FF at times, but a clear of the mewe.com related cookies and relogin at mewe via FF clears up the issues of things not wanting to display correctly or fully on mewe using FF - which is why I thought clearing 12cdrc.org cookies would help in this case (but did not, again, made the malfunctioning worse)!

This makes little sense. I even tried doing D/L of full 89.0.1 install, didn't help.

I'd like to try and RESTORE COOKIES (last thing I want to do is clear all data/cookies for FF) for 12cdrc.org from manual offload of all my userid appdata folder/sub-folders to an external drive (or perhaps appdata backup to Norton cloud backup done a few weeks ago)! But I do not know where to look. Was about to go to my external drive and do complete file search of "12cdrc*.*" to see what would return when I thought I could search Mozilla/FF Help on "Restore Cookies" but only very old question for very old version of FF showed up and it said "IF STILL NEED HELP ASK NEW QUESTION" so here I am doing so!!!

Again, all sites (12CDRC.org, MeWe.com, and RescueMichigan.com) ALL WORK 100% error/issues free using Brave, Chrome, Edge, so this is FIREFOX SPECIFIC and all these issues have started under/after recent FF updates and/or gotten worse, not fixed/better, under updates/upgrades!!!!

Appreciate any Help... 1) like I said, where the Cookies are hidden that I might then recover them from previous save 2) other suggestions?!?!?!

Hi, I developed a simple Add-on, based on jQuery. Unfortzunately, it seems "ajaxStop()" does consistently not work as expected (at all). Any tips on what to consider to get ajaxStop to succesfully trigger my registered eventhandlers? Thanks

PS off topic: the "developer" area of Mozilla is quite painful to handle and reach. I'm always pushed/forwarded back over here. Also the sophisticated 2way-auth seems a bit overkill for posting on a forum .

Hello, I'm on the way to be a web developer. But, when it comes to add Glassmorphism effect, it seems like firefox doesn't support CSS property called "backdrop-filter". Will there be any support for this in near future?

I am creating a split-flap. It works fine in Chrome, but in firefox, during the second rotation period, it is not smooth as in chrome. How can I fix it?
