When writing mediaqueries I use em as a unit, not pixels. But the actual screensizes (and rulers and measurements) in Responsive Design Mode are in pixels. So I have to use a pocket calculator to get the corresponding em (pixels / 16) or guess. How can I get direct measurements in ›em‹?

Hi,

In the context of an app using Pixi.js to render markers on a map, we have noticed that Firefox is unable to load SVG images from a data URL, as soon as they have a width/height in percentage.

Switching to a px size fixes the problem.

But what bothers me the most, is that this fails seems to be silent, there is no way to catch the error and bubble it up to the developer. So the image just never loads in our code, which makes the issue extremely difficult to figure.

See more information, and a reproduction with Pixi.js there: https://github.com/pixijs/pixi.js/issues/7473

Hello..............when I open a new Firefox browser tab, I see the heading Top Sites and a selection of eight links, most of them to the websites that I use frequently.

Needing 12 rather than eight, I found the facility to select a second row. But the second row also has eight links and some of them are not wanted.

Please tell me how I can select 12 links and stop at that number. If I right click the three dots in the top right corner of one of the unwanted links and then select Dismiss, another unwanted link replaces it.

I know this is a simple problem but it has defeated me. Please help.

And thank you..................Richard

I use Firefox on iOS and I have correctly set it as my default browser. What is annoying, however, is the fact that when I select a text and I click on "Search on the web", iOS opens Safari and not Firefox. Why does this happen? I want to open Firefox when I click on that button.

Thanks for you reply.

I am trying to use css mix-blend-mode in combination with video. It works on every browser, and every device. BUT it does not work on Mac with firefox browser...

See the codepen For those without a mac, see the screenshot

Does someone know the solution to this problem? I was thinking about adding a fallback support with '@supports (mix-blend-mode: multiply)', but this will always return true in this case because it is supported on firefox...

Thank you for the help and your time.

When using the "Checkout with PayPal" button on websites the PayPal popup window appears however it's impossible to progress to the checkout. When I then use Edge and do my purchase through there, the PayPal popup window allows me to enter my info and then proceed to PayPal with no problem at all.

I have added paypal.com into exclusions for 'Block pop-up windows' and Enhanced Tracking Protection

But, I want to be able to use Firefox! I do not want to be forced into having to use Edge for purchase payments using PayPal. I am not a techie and would like a simple solution w/o having to get into modifying any programming files. S.O.S.

Something happened to Firefox over the weekend-- update or otherwise. Lost all my tabs. Had to uninstall and reinstall. Re-do all my settings. Re-set all my pinned tabs for work. Now I can't get into Asana, a project management tool I use for work daily and have used for years, because of the below security message. I've tried everything I can think of but can't get Firefox to open Asana.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to app.asana.com because this website requires a secure connection.

What can you do about it?

app.asana.com 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.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

Can we maybe add a show once option or similar, in my case I use Tabliss which could also be the culprit -- but it seems to me disabling this notification should be an option or even better, have it actually show once.
