An e-banking site that worked in Firefox for years no longer works in 145.0 under Ubuntu Studio 24.04.1 This is the help page for the error I am receiving: https://support.mozilla.org/1/firefox/145.0/WINNT/en-US/connection-not-secure However, the error message I received (see attached image) is not listed there. Since the e-banking site hasn't changed in ages, I suspect instead something in one of the recent Firefox updates. The site works fine in Safari under Sequoia 15.5 on a MacBook Air, and I can login in Firefox, so I doubt that there is a problem with the site's security certificate. Since both the MacBook Air and the Ubuntu PC are on the same LAN, I also doubt any network obstruction. I haven't found a wax to get any more detailed error information and would be grateful for tips on how to do so. Meanwhile, I would like to at least change from the standart Firefox release to the ESR veersion, but find no information on how to do so. I have currently set up Firefox to be pulled from the instructions in https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions-recommended under "For Debian Trixie and Newer" How can I switch from my current Firefox under Ubuntu to an ESR release?

I am now receiving this notice for more and more commonly accessed websites. I get the message if I have https only selected or not selected. Currently receiving for Lowes, Home Depot, American Airlines and more. I can go to a Firefox 135.0.1 browser on a separate desktop accessing the internet through the same router and do not have issues. I suspect I have been upgraded by Mozilla into a less functional browser version for whatever reason that Mozilla does this.

I am using Pop OS. Videos are not playing in firefox. In youtube it shows loading infinitly. In reddit all videos become green. I tried playing a downloaded video it also become green. These are only happening in integrated mode. If I use hybrid graphics mode all works good. I attached the about:support page and about:config page.

about:config page link about:support page

These files are taken in integrated graphics mode.

I keep getting sporadic crashes, and sometimes a tab crash (particularly on maps.google.com). I have the latest updates to all my software. What can I do to help prevent these crashes?

A month ago I downloaded Linux Ubuntu 24.04.3 onto my Microsoft Surface Pro. Was never able to get the touch screen to work, but, the printer worked fine. After the recent Firefox update, however, I am unable to print. The preview page does not load. Not tech savvy, here, definitely not an administrator. How do I fix this? Thanks for any help.

Hi all, I remember in older versions of Firefox (within the past 6 months) that pdfs embedded in a page would be a hyperlink that you had to click which would open in another tab. Now pdfs automatically open which is very annoying as it makes it difficult to read, while I found a way to open it in another tab I was wondering if there is a setting I can disable so I can just click on a hyperlink.

Thanks in advance

What version of Firefox actually allows you to add extensions? I'm running the most current version of Tumbleweed that ships with 144.0. Attempts to add extensions just sit there doing nothing until I close the tab. This sort of worked some time ago (I forget the version) but the inability of Firefox to allow add-ons/extensions is getting to be a joke. There are other browsers out there, ya know.

Previous version, if I added a new bookmark, I would be presented with options on Where(Folder) and Tags. This is no longer offered, and bookmarks are just added to unknown within bookmarks Q. What has changed, and how do I get this option back?

FF bug (?) (my own tests), Chrome works as expected, was also gemini ai discussed.:

 Why for the following css rule (new FF):
 header:has(~ noscript) ~ * div[class*="-slider"] {width: calc(var(--number-of-slides) * 100%);}
 the --number-of-slides is defined and visible:
 header:has(~ noscript) ~ * div[class*="-slider"] {--number-of-slides: 1}
 but this one isn't at all:
 header:has(~ noscript:has([value="1"])) ~ * div[class*="-slider"] {--number-of-slides: 1}
 And all remembering that in the noscript there is direct descendant having value="1"

As mentioned it works as expected (so average person naturally may think it sould) well for Chrome - noscript is visible, js disabled, controls are visible. Sophisticated use case of :has() but it sort of "has right" to happen.
