Firefox Community Forum

Hello,

We have set a fixed proxy in Firefox on our employees' notebooks. However, when the notebooks do not have a VPN connection to our network, the proxy cannot be reached. Firefox then disables the proxy after a short time. I found the setting network.proxy.failover_direct under about:config and thought that setting it to false would solve the problem. However, Firefox behaves the same way.

How can I prevent Firefox from accessing the internet except through the specified proxy?

Thank you.

Le titre décrit déjà pas mal ce que je recherche: à propos des épingles de la page d'accueil, c'est pas très clair pour les urls qu'on peut mettre (web, certes mais), je mets par exemple un lien google drive pour l'icône mais à ce moment l'image n'est pas bien centré.. Il faudrait un lien qui affiche telle quelle l'image. Dès que la page ciblée n'est pas uniquement l'image, il y aura des bords ou autres.

Comment faire à ce moment là?

Hi,

I am using Firefox 78.15.0esr (64-bit) on a 16+ year old MacMini with el Capitan. I use it for various low performance use cases like playing music, and for testing the performance of my webapplications on old hardware, using outdated software

Reading the attached message (and followed up information page), I understand that I can still use this version of Firefox. But that all add-ons will be disabled in two months. Which is very upsetting to say the least. Why is a stand-alone add-on that doesn't communicate with an outside server being disabled?

Given that I run an unsupported(?) version of MacOS which I can not upgrade, I won't be able to update Firefox to the version that is being suggested. This means that Mozilla (the party that I've always cheered on for its vision), now remotely limits my access to the internet because of a certificate that they used in the development of the software becomes obsolete. This is a move that I'd expect from Google, Microsoft or Apple, but not from Mozilla.

Could someone with a more technical background explain me how such a certificate is related/integrated in the build of Firefox (78). I mean, why isn't it possible to re-build the project with a newer root certificate, given all of the source files are online: https://archive.mozilla.org/pub/firefox/releases/78.0/ ?

Hello I am presently running OS10.9.5 on a MacMini from 2013 because there are some expensive programs on there that I will lose when I update the OS. I now know I need to do that regardless. My question is: What OS version should I upgrade to for a secure version of Firefox and, MOST IMPORTANTLY... will my Comcast email account and bookmarks be carried into the upgraded Firefox browser? Thanks. a concerned Gary Bellucci

I am a Cacti developer and we are considering switching from FontAwesome Web Fonts to Tabler Web Fonts. However, on Firefox for Windows only, we are having a major slowdown when using the Tabler SVG based webfonts. The page load is first stalled by Firefox apparently loading all the Web Fonts, which would appear normal with any browser (though exceedingly slow on Firefox for some reason).

However, once the page is loaded, when going off tab to another browser tab, and then back to the Firefox tab that includes the Tabler webfonts, there is a 3 second delay before the tab switches. When we enable the performance analyzer, we find that the delay is almost 100% Reflow of the page, even though the page is static as this point (no changes) from the last time it was activated.

We do not have this issue on Firefox for Linux, MS Edge or any other Chromium browser, only Firefox on Windows. I'm using the latest version 134. Should I be opening a bug?

Since updating to the above OS on my Macbook Pro I have not been able to use any screen share functions (e.g. Adobe, MS PowerPoint etc) while using Firefox - all of which worked fine before. I've tried all kinds of suggestions including from this forum but nothing has worked. The site I use most is Konfidens. The only option that comes up when clicking on Share Screen is Use Operating System Settings (see attached screenshot). When you click on it the only option is "share entire screen" which isn't what I need or want. The Konfidens tech support team is looking into this but given the screen share option works fine on Chrome, the problem is evidently with Firefox. I want to stick to Firefox for security reasons but if I cannot resolve this, I will have no option but to move across to another browser. Many thanks in anticipation!
