F.F. version: 73.01 for linux os: linux mint 19.1

Install and click tab for vue devtool. Font resize(ctrl and +) or (ctrl and -). The menu bar above vue devtool resizes but the viewing area of vue devtool fails resizing. Clicking in vue devtool area does not help. Click outside vue devtool and on the content area. Then resize. Works as expected. Click on inspector tab. Resize, works as expected.

Tested vue devtool resizing on linux chrome. Works as expected.

Hi Guys, Can you explain why FireFox can't upload .js files? Apparently Firefox can't upload either external or internal .js file. Therefore the website rendering is not what it should looks like. I don't know where it's coming from since on Chrome it looks as it should be.

Thank you in advance for your help. Nicolas

Pages start to load then stop

I have a php site that is using a MySQL dB and has a few JavaScript1.2 elements on the page. After updating from Firefox 68 to 74 some of the pages have stopped loading. It starts to connect and I can see the queries running on the database but Firefox gives up before the queries return any values. If I click on a link again after it stops loading it sometimes goes through and finishes loading or downloads a generated file on the second or third try. the amount of time before it gives up seems to vary each time.

I have tried disabling JavaScript to see if that has any effect but it didn’t help. as well as seeing if it was a variable that changed in about:config but haven’t found anything that has made a difference.

I have other computers running older versions and they all load the site like they should and it also works in chromes latest version, safari and IE.


If anyone has any ideas on what could be wrong it would be much appreciated. I have been stuck on this for about a week now with no luck.

I have custom desktop app which can be opened from Web. IE, Edge shows just popup messages that such app is not installed. But FireFox reloads the page with the error (replacing my Web app) and shows The address wasn’t understood (yes, address doesn't exist but why doesn't it show just popup message without this error message)? Is it configurable,any suggestion to remove such reload? Thanks

On many websites FF does not show the saved username like it would show the password. I'm a web developer. How can I make Firefox show the saved username hint? I have seen this working correctly at the Twitter login, for example, but I don't spot any difference. Is Twitter using some JS to make that happen? There was an unsolved question a year ago about this https://support.mozilla.org/en-US/questions/1227914

Hello, I have deployed a new version of my site (internal, sorry) and Firefox keeps caching it although I don't see the reason for it.

This is the info about it in 'about:cache' (I deployed a new version at 10:20):

key: https://[URL-OF-THE-SITE]/ fetch count: 6 last fetched: 2020-05-05 10:17:05 last modified: 2020-05-05 10:23:31 expires: 2020-05-05 11:04:08 Data size: 5758 B Security: This is a secure document.

In the Firefox Developer Tools I always get "5,62KB (raced)" (see attached image) and looking at my server logs, it does actually fetch the page, but it still shows an old version. The content supplied by the server is definitely the new version and other browsers don't seem to have this problem.

Thanks in advance for your help!

Edit: The etag has changed between the two versions.

I'm developing website. In css media query @media (pointer: coarse) is true and @media (pointer: fine) is false. But I'm working on laptop without touchscreen. In attachment there is screenshot from https://developer.mozilla.org/en-US/docs/Web/CSS/@media/pointer It shows what I'm talking about. Only Firefox has this behavior. Ie11, Edge, Chrome working as expected (css media query @media (pointer: coarse) is false and @media (pointer: fine) is true).

So question, why FF behaves this way? is it a bug? Is there is any workaround for Firefox?

I have content security policy headers defined for my site. However, I have nothing defined for script-src. When I load a certain page from my site in Firefox 76.0 I see the following messages in the console:

Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”). 8 utils.js:35:9 Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”). 2 gps.js:231:11 Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”). 4 utils.js:35:9 Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”). gps.js:231:11 Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”). 3 utils.js:35:9

When I load the same page in Chromium, I see no such messages in the console.

Furthermore, there are no utils.js and gps.js scripts in the source of the loaded page. Finally, I see no problems with the display or the functionality of the page. Clearing all the cookies and the caches (local and server) has no impact on this issue. There are many other javascripts on the page, both inline and not, which do not appear to be affected but the existing settings.

So, my questions: 1) Why do these messages appear? 2) Is this an issue that I need to fix or can I safely ignore it? 3) what do the numbers after the script names mean? (gps.js:231:11 utils.js:35:9)

I have a website development system with SSL enabled for testing. The certificate is self-signed but expired. I added a new self-signed certificate. When I load a development website, Firefox issues a Warning: Potential Security Risk Ahead. When I click Advanced, the error is SSL_ERROR_BAD_CERT_DOMAIN, with additional information that the certificate has expired. Clicking Accept Risk and Continue loads an ISP website with network details of attached devices. I have repeatedly cleared Firefox cached and saved data by clearing recent history, followed by clearing everything for all the check boxes on the page. I have examined the certificates in the security settings, view certificates. The expired certificate is listed. After deleting the expired certificate from the list, and loading the development website again, results in the same problem all over again.

I have no problem with Safari or Chrome browsers, only Firefox. Firefox 76.0.1, Mac OS 10.14.6. MAMP based development system, version 5.7 using Apache.

How can I delete the expired certificate so it stays deleted, and make Firefox use the new certificate?

My local webconfig has the redirect to HTTPS rule disabled. So I am going to localhost, at least not with FF Developer or regular FF has the same error.

Works fine on Chrome and Opera.

Hi,

the css animation of the svg:circle looks weird. It seems that the size of the bbox does not follow the size of the circle itself. As a result the circle from time to time is cut at borders. I have not faced this problem with other browsers. The problems seems to appear on Windows 7/10 only. On Mac this looks better.

When I use SVG animation all is fine. https://jsfiddle.net/gex5rL3o/

I was wondering if there way a way to override Firefox's default JS memory limit per tab? Right now, upon reaching about 4-5GB of memory usage, my JS console window reports an our of memory error and dumps my code. I appreciate that this is pretty normal behavior, as 4GB of memory is fairly outlandish for a website. However, for the use case of VR, particularly in physics engine development, it can feel a bit restrictive and even silly when I have 32GB sitting idle - and I could readily double that to 64. However, I know Firefox has a rather extensive about:config section - and I was wondering if anyone knew if one of these variables allowed us to override the internal limits of the browsers memory limitations?

I write web applications for a living, and that means that part of the time I am creating on-the-fly Excel and PDF documents. Often I have to edit the document for some tiny formatting detail (e.g. the borders are too thin, a misspelling, the headers should be bold, etc), restart the application and re-download the new file to check whether it is correct. After I do this 4 or 5 times, Firefox starts caching the files and gives me old versions instead. I've deleted all of the past files from the temp folder manually, and still receive the old file. If I connect to the same program in Chrome, I get my new document, so I know that it's not the application. How to I get Firefox to stop caching download files, period? I don't want to click a button to clear out my whole cache every time I restart the application....

Thanks!
